## ซึ่งการประกาศตัวแปรในภาษาGo นั้น เขียนได้ 2 แบบคือ
- เติมคำว่า `var` ข้างหน้าชื่อตัวแปรพร้อมกับ type ข้างหลังเช่น `var a1 string` นั่นหมายความว่า เราได้สร้างตัวแปรที่ชื่อว่า a1 ที่มี type เป็น string ขึ้นมาแล้วนะ ซึ่งมีค่า zero value คือ empty string
> เอ๊ะ แล้ว zero value มันคืออะไร ?
> zero value ก็คือค่า default ของ type นั้นๆ เมื่อเราประกาศตัวแปรแบบไม่ได้ระบุค่ามันจะมีค่าเป็น default value เสมอ ซึ่ง string มีค่าเป็น "" หรือที่เรียกกันว่า empty, int ก็จะมีค่าเป็น 0, bool มีค่าเป็น false, slice มีค่าเป็น nil อะไรประมาณนี้
กลับมาเรื่องการประกาศตัวแปร ถ้าเราต้องการประกาศตัวแปรพร้อมกับระบุค่าเราก็จะเขียนได้แบบนี้ `var a1 string = "Hello world"` หรือ `var a1 = "Hello world"` ซึ่งแบบหลัง เราไม่ต้องระบุ type ก็ได้ เพราะภาษาGo มันเดาค่าที่คุณระบุเข้าไปได้
- การประกาศตัวแปรอีกแบบ เราเรียกมันว่า `shorthand` ซึ่งเขียนได้แบบนี้คือ `a1 := ""` หรือถ้าอยากระบุค่า ก็แค่เขียนแบบนี้ `a1 := "Hello world"`
## แล้ว 2 แบบนี้มันต่างกันยังไง?
- การประกาศแบบใช้ `var` มันสามารถประกาศนอก function ได้ เป็น `global variable` (ตัวแปรที่ function หรือ package ใดๆ ก็สามารถเรียกใช้ได้) ในขณะที่การประกาศแบบ `shorthand` มันไม่สามารถประกาศนอก function ได้ ต้องเขียนใน function เท่านั้น
- การประกาศแบบใช้ var สามารถที่จะ `ไม่ระบุค่าได้` กล่าวคือ หากคุณประกาศ boolean แบบ `var a1 bool` คุณก็จะได้รับค่า zero value ที่เป็น false เลย ในขณะที่การประกาศแบบ `shorthand` คุณต้องระบุค่าให้มันเสมอ นั่นก็คือ `a1 := false`
เพื่อให้เห็นภาพ ให้คุณลองดูโค้ดนี้ดู
ลองสังเกตุดีๆ จะเห็นว่า ต้วแปร a2 ที่อยู่นอก func main กับ a2 ที่อยู่ใน main ทำไมมันถึงสามารถใช้ชื่อเดียวกันได้ นั่นก็เพราะว่า มันทำงานกันคนละ scope มันคือคนละตัวกัน ถ้าคุณประกาศตัวแปรที่ชื่อ a2 ใน function main คุณจะไม่มีทางใช้ตัวแปร a2 ที่อยู่นอก main ได้ แต่ถ้าหากคุณต้องการใช้ตัวแปร a2 ที่อยู่ข้างนอก main ละ ต้องทำยังไง? คำตอบก็คือดูในรูปนี้
ที่นี่ลองพิจารณาดูรูปข้างล่างนี้ดูว่าทำไมถึง error ล่ะ
> คำตอบก็คือ คอมพิวเตอร์มันอ่านโค้ด มันอ่านจากบนลงล่างมาเรื่อยๆ
> บรรทัดที่ 9 บอกว่า a2 เป็น `int` นะ (จากการระบุค่า 10 เข้าไป) เมื่อมาถึงบรรทัดที่ 10 เราประกาศ `var a3 bool = a2` นั่นหมายความว่า มันจะไปเอาค่าจาก a2 บรรทัดข้างบนล่าสุด นั่นก็คือบรรทัดที่ 9 ใส่ให้กับ a3 ซึ่งมันจะเป็น `var a3 bool = 10` หรือเปล่า?
เปล่า มันไม่สามารถเป็นแบบนั้นได้ เพราะภาษาGo เป็นภาษาที่คุณประกาศ type อะไรมา คุณต้องระบุค่าเข้าไปให้ถูกต้องกับ type ดังนั้นจากตัวอย่างนี้มันเลยระบุไม่ได้ เพราะ a3 เราประกาศเป็น boolean ซึ่งค่าของ boolean คือ `true` กับ `false` ส่วน `10` นั้นเป็นตัวเลข มันเลยเกิด error นั่นเองง
## กลับมาที่ var กับ := แล้วเราจะใช้แบบไหนดีล่ะ? ผมสรุปให้ว่า
```
การประกาศตัวแปรแบบใช้ var นั้น
- เหมาะสำหรับการประกาศตัวแปรในระดับ package
- ใช้เมื่อคุณต้องการระบุชนิดข้อมูลอย่างชัดเจน
- ใช้เมื่อคุณต้องการประกาศตัวแปรโดยไม่ต้องกำหนดค่าเริ่มต้น
```
```
ส่วนการประกาศตัวแปรแบบใช้ := นั้น
- เหมาะสำหรับการประกาศตัวแปรภายในฟังก์ชัน
- สะดวกและรวดเร็วในการเขียนโค้ด โดยไม่ต้องระบุชนิดข้อมูล
- ใช้เมื่อคุณต้องการประกาศและกำหนดค่าเริ่มต้นในบรรทัดเดียว
```
แต่ทั้งนี้ทั้งนั้น มันก็แล้วแต่ความสะดวกของคุณเองแหละ แต่ใช้ให้ถูกหลักมันก็เป็นสิ่งที่ดี :)

Behind every big win, there’s a story of skill, research, and meticulous planning. This blog explores some of the most remarkable **[Big Betting ](https://www.bigbetting.io/)**success stories and delves into the strategies and mindsets that have led to these victories. Whether you're a novice bettor or an experienced one looking for inspiration, these stories highlight how the pros consistently beat the odds.
**The Journey of Successful Bettors**
**The Mindset of a Pro Bettor**
Success in betting starts with the right mindset. Professional bettors approach betting as a business, with a focus on long-term profitability rather than short-term wins. They possess traits such as discipline, patience, and emotional control. Understanding the psychology behind betting and managing one's emotions are crucial aspects that distinguish pros from amateurs.
**Bankroll Management**
One of the fundamental principles that professional bettors adhere to is effective bankroll management. They allocate a specific budget for betting and stick to it, regardless of wins or losses. This disciplined approach helps in minimizing risks and ensuring sustainability. By managing their bankroll wisely, pros can withstand losing streaks and capitalize on winning opportunities without jeopardizing their financial stability.
**Iconic Betting Success Stories**
**Billy Walters: The Legend of Sports Betting**
Billy Walters is arguably one of the most successful sports bettors of all time. Over his 40-year career, Walters achieved a winning percentage of around 57% in sports betting, a remarkable feat considering the industry average. His success is attributed to a combination of extensive research, sophisticated statistical models, and insider information.
Walters’ betting strategy involved identifying inefficiencies in the betting markets and exploiting them. He invested heavily in research and employed a team of experts to analyze data, making informed decisions that often went against popular opinion. Walters’ disciplined approach and willingness to take calculated risks set him apart in the world of sports betting.
**Zeljko Ranogajec: \
The High Roller**
Zeljko Ranogajec, an Australian professional gambler, is known for his extraordinary success in horse racing and various casino games. Starting as a blackjack player, Ranogajec utilized his mathematical prowess to develop card-counting techniques that gave him an edge over the house. His transition to horse racing saw him employing similar analytical skills, using complex algorithms to identify profitable betting opportunities.
Ranogajec’s success is also attributed to his extensive use of syndicates. By pooling resources with other bettors and sharing information, he maximized his chances of winning. His methodical approach and reliance on data-driven strategies have earned him a reputation as one of the most successful bettors in history.
**Haralabos Voulgaris:
The NBA Betting Guru**
Haralabos Voulgaris made a name for himself in the world of NBA betting. His success story began in the early 2000s when he noticed inefficiencies in the betting lines set by sportsbooks. Voulgaris leveraged his deep understanding of basketball and statistical analysis to exploit these inefficiencies, consistently making profitable bets.
Voulgaris' approach involved watching countless hours of game footage, analyzing player tendencies, and developing predictive models. His ability to identify patterns and trends that others overlooked allowed him to stay ahead of the bookmakers. Voulgaris' dedication to research and his analytical mindset were key factors in his betting success.
**Strategies That Lead to Success**
**Research and Analysis**
One common thread among successful bettors is their commitment to research and analysis. Pros spend significant time studying statistics, historical data, and trends to make informed decisions. They utilize various tools and resources, including advanced software and expert opinions, to gain a comprehensive understanding of the betting landscape.
**Value Betting**
Value betting is a strategy where bettors look for odds that are higher than they should be based on their own assessment of the event's probability. By identifying these discrepancies, bettors can place bets that offer a positive expected value. This approach requires a deep understanding of the sport or event and the ability to accurately assess probabilities.
**Diversification**
Successful bettors diversify their bets to spread risk and increase their chances of profitability. Instead of putting all their money on a single bet, they place multiple smaller bets across different events. This strategy helps in managing risk and ensuring that a single loss doesn’t significantly impact their bankroll.
**Staying Informed**
In the fast-paced world of betting, staying informed about the latest developments is crucial. Professional bettors keep themselves updated with news, injuries, weather conditions, and other factors that can influence the outcome of events. This real-time information allows them to make timely and informed betting decisions.
**Lessons from the Pros**
**Patience and Discipline**
Patience and discipline are virtues that every successful bettor possesses. They understand that betting is a long-term game and that short-term losses are part of the process. By maintaining discipline and not chasing losses, they avoid making impulsive decisions that can lead to significant financial setbacks.
**Continual Learning**
The betting landscape is constantly evolving, and successful bettors are always learning and adapting. They invest time in improving their skills, studying new strategies, and staying abreast of industry trends. This continual learning process allows them to stay ahead of the curve and maintain their competitive edge.
**Networking**
Building a network of contacts within the betting community can provide valuable insights and opportunities. Successful bettors often collaborate with others, sharing information and strategies to enhance their betting success. Networking with other professionals can also provide access to insider information and expert opinions.
**Conclusion**
The success stories of professional bettors like Billy Walters, Zeljko Ranogajec, and Haralabos Voulgaris demonstrate that betting is not merely a game of chance but a strategic and calculated endeavor. Their journeys highlight the importance of research, discipline, and a data-driven approach in achieving long-term profitability. By adopting the strategies and mindsets of these pros, aspiring bettors can improve their chances of success and navigate the complex world of betting with confidence.
Betting, when done responsibly, can be a rewarding pursuit. The key is to approach it with the right mindset, equipped with knowledge and strategies that have been proven to work. As these success stories show, with dedication and a methodical approach, it is possible to achieve significant success in the world of **[Big Betting](https://bigbetting.in/)**.

This article aims to compare these three state management libraries, exploring their strengths, weaknesses, and best use cases to help you make an informed decision for your next project.
1. Redux
Overview:
Redux is arguably the most well-known state management library in the React ecosystem. It is based on the principles of Flux architecture and emphasizes a unidirectional data flow.
Strengths:
Predictable State Management: Redux enforces strict rules on how state changes occur, which makes it easier to track changes and debug issues.
Large Ecosystem: Being widely adopted, Redux has a robust ecosystem with numerous middleware options (like redux-thunk and redux-saga) and developer tools.
Community and Documentation: Redux benefits from extensive documentation and a large community, providing ample resources for learning and troubleshooting.
Weaknesses:
Boilerplate Code: Redux is often criticized for the amount of boilerplate code required to set up and manage state, which can make simple tasks feel cumbersome.
Complexity: For small to medium-sized applications, Redux can introduce unnecessary complexity, making it harder to justify its use.
Best Use Cases:
Large-scale applications where state predictability and debugging capabilities are paramount.
Applications with complex state logic that require middleware for side effects management.
2. MobX
Overview:
MobX offers a reactive approach to state management, focusing on simplicity and ease of use. It allows developers to manage state through observables and reactions.
Strengths:
Simplicity and Minimal Boilerplate: MobX is known for its straightforward API and minimal boilerplate, making it quick to set up and use.
Reactivity: MobX automatically tracks state changes and updates components, reducing the need for manual intervention.
Flexibility: MobX can be used with or without React, making it versatile across different frameworks.
Weaknesses:
Less Predictable: While MobX's reactivity is powerful, it can sometimes lead to less predictable state changes compared to the strict unidirectional flow in Redux.
Community and Ecosystem: MobX has a smaller community and ecosystem compared to Redux, which might limit the availability of third-party tools and resources.
Best Use Cases:
Small to medium-sized applications where quick setup and simplicity are desired.
Applications where reactivity and automatic state updates can significantly enhance user experience.
3. Recoil
Overview:
Recoil is a relatively new state management library developed by Facebook. It aims to provide a simple, yet powerful state management solution with a focus on concurrent mode compatibility in React.

Concurrent Mode Compatibility: Recoil is designed to work seamlessly with React's concurrent mode, making it future-proof for upcoming React features.
Minimal Boilerplate: Similar to MobX, Recoil offers an intuitive API with minimal boilerplate, easing the development process.
Atom and Selector Model: Recoil introduces the concept of atoms (state units) and selectors (derived state), providing a flexible and modular state management approach.
Weaknesses:
Maturity: As a newer library, Recoil's ecosystem and community are still growing, which might pose challenges in terms of available resources and support.
Performance Considerations: Depending on the complexity of state interactions, Recoil might require careful management to avoid performance bottlenecks.
Best Use Cases:
React applications aiming to leverage concurrent mode and modern React features.
Projects where a simple, modular approach to state management is preferred, without the overhead of extensive boilerplate.
Conclusion
Choosing the right state management library depends on various factors, including the scale of your application, team familiarity, and specific project requirements.
Redux is ideal for large-scale applications requiring strict state predictability and debugging tools.
MobX excels in small to medium-sized projects where simplicity and reactivity are paramount.

1,912,689 | Paper detailing BitPower Loop’s security | Security Research of BitPower Loop BitPower Loop is a decentralized lending platform based on... | 0 | 2024-07-05T11:42:07 | https://dev.to/asfg_f674197abb5d7428062d/paper-detailing-bitpower-loops-security-3hoa | Security Research of BitPower Loop
BitPower Loop is a decentralized lending platform based on blockchain technology, dedicated to providing users with safe, transparent and efficient financial services. Its core security comes from multi-level technical measures and mechanism design, which ensures the robust operation of the system and the security of user funds. This article will introduce the security of BitPower Loop in detail from five aspects: smart contract security, decentralized management, data and transaction security, fund security and risk control mechanism.
1. Smart Contract Security
Smart contracts are the core components of BitPower Loop, and their codes must undergo strict security audits before deployment. These audits are usually conducted by third-party independent security companies to ensure that there are no vulnerabilities or malicious code in the contract. In addition, the immutability of smart contracts means that once deployed, no one (including the development team) can modify its rules and logic, which fundamentally eliminates the possibility of malicious operations. All operations are automatically executed by smart contracts, avoiding the risk of human intervention and ensuring the fairness and consistency of system operation.
2. Decentralized Management
BitPower Loop eliminates the risks brought by single point failures and central control through decentralized management. The system has no central management agency or owner, and all transactions and operations are jointly verified and recorded by blockchain nodes distributed around the world. This decentralized structure not only improves the system's anti-attack capabilities, but also enhances transparency. Users can publicly view all transaction records, which increases trust in the system.
3. Data and transaction security
BitPower Loop uses advanced encryption technology to protect users' data and transaction information. All data is encrypted during transmission and storage to prevent unauthorized access and data leakage. The consensus mechanism of the blockchain ensures the validity and immutability of each transaction, eliminating the possibility of double payment and forged transactions. In addition, the automated execution of smart contracts also avoids delays and errors caused by human operations, ensuring the real-time and accuracy of transactions.
4. Fund security
The secure storage of user funds is an important feature of BitPower Loop. Funds are stored on the blockchain through smart contracts and maintained by nodes across the entire network. Distributed storage avoids the risk of fund theft caused by centralized storage. In addition, the user's investment returns and shared commissions are automatically allocated to the user's wallet address by the smart contract after the conditions are met, ensuring the timely and accurate arrival of funds.
5. Risk Control Mechanism
BitPower Loop effectively manages lending risks by setting collateral factors and liquidation mechanisms. The collateral factors are independently set according to market liquidity and asset value fluctuations to ensure system stability and lending security. When the value of the borrower's assets falls below a certain threshold, the liquidation mechanism is automatically triggered, ensuring the repayment of the borrower's debt and protecting the interests of the fund provider. In addition, the immutability and automatic execution characteristics of smart contracts further enhance the security and reliability of the system.
Conclusion
BitPower Loop achieves high security and stability through multi-level security measures and mechanism design. Its smart contracts are strictly audited and immutable, decentralized management eliminates single point failure risks, advanced encryption technology protects data and transaction security, distributed storage ensures fund security, and risk control mechanisms manage lending risks. These security features together build a reliable decentralized financial platform that provides users with secure, transparent and efficient financial services.

[Introduction](#intro)
[Requirements](#require)
[Steps on Hosting a Static website on Azure Blob Storage] (#steps)
### Introduction <a name="intro"></a>
A static website is a website whose content is constant. They present the same content to all users and do not use databases or server-side processing. The contents are not generated using server-side scripting languages like PHP, Java, Ruby, Pithon rather they are built using front end languages like HTML, CSS and JavaScript.
Azure blob storage is a type of storage in Azure that store massive amount of unstructured data. Blobs are organized in a container. A container can store unlimited number of them. A container is located in a storage account.
What does it mean to host a website? To host a website also known as web hosting is to make a website available and accessible on the internet. Hosting your content in Azure storage enables you to use serverless architecture. it is a good option when you do not require a server to render your content.
[_back to Contents_](#content)
### Requirements <a name="require"></a>
This guide uses Visual studio code to deploy already built static website to Azure blob storage. Hence, you need to do the following:
- Download and install Visual studio code.
- install extensions like Azure Account and Azure Storage on the Visual Studio Code. The extensions will be used by visual studio code to deploy your static website to Azure Storage.
- Already created static website saved in a folder.

1,912,680 | Automating User Creation and Management with Bash Scripting: A Detailed Guide. | Introduction: Linux, being a multi-user system, empowers administrators to create users... | 0 | 2024-07-05T11:31:25 | https://dev.to/kalio/automating-user-creation-and-management-with-bash-scripting-a-detailed-guide-pmh | devops, sysops, bash, linux | ## Introduction:
Linux, being a multi-user system, empowers administrators to create users and groups, each with specific permissions. When users are assigned to groups, they acquire the group's permissions. Effective user and group management is essential for system administration, from small personal servers to extensive enterprise networks. Streamlining the user creation process is crucial for ensuring security, organization, and efficiency, and Bash scripting provides a powerful means of automating these tasks.
This guide will walk you through creating a Bash script for managing user accounts on a Linux system.
## The problem
Your company has employed many new developers. As a SysOps engineer, it's your responsibility to efficiently manage user accounts and their associated permissions. To streamline this process, you are tasked with writing a Bash script that automates the setup and configuration of new user accounts based on predefined criteria.
-
**User and Group Definition:** Users and their groups are defined in a text file that will be supplied to the script as an argument.
-
**Home Directory Creation:** A dedicated home directory should be created for each user
-
**Secure Password Storage:** User passwords should be stored securely in a file with path `/car/secure/user_passwords.txt`
-
**Logging Actions:** Logs of all actions should be logged to `/var/log/user_management.log` for auditing and troubleshooting purposes.
-
**File Access Control:** Only the owner, in this case root, should be able to access the `user_password.txt file`, ensuring that unauthorised access is prevented.
-
**Error Handling:** Errors should be gracefully handled
## Prerequisites
To begin this tutorial, ensure you have the following:
-
A Linux system with administrative access.
-
Basic familiarity with Linux commands.
## The Script:
The script, `create_user.sh`, automates user account creation, password encryption, group assignment, and logging activities on a Linux system. The goal is to streamline user management and ensure that all actions are securely recorded and auditable. Below is a detailed breakdown of each section of the script, including its purpose and functionality.
**The shebang.**
```
#!/bin/bash
```
This specifies the type of interpreter script will be run with. Since it is a "bash" script, it should be run with the Bourne Again Shell (Bash) interpreter. Also, some commands in the script may not be interpreted correctly outside of Bash.
**Defining File Paths and Variables**
Next, create some environment variables that will hold the text_file.txt, the logs file path (var/log/user_management.log), and password file path (/var/secure/user_passwords.csv).
```
LOG_FILE="/var/log/user_management.log"
PASSWORD_FILE_DIRECTORY="/var/secure"
PASSWORD_FILE="/var/secure/user_passwords.txt"
PASSWORD_ENCRYPTION_KEY="secure-all-things"
USERS_FILE=$1
```
-
`LOG_FILE`: specifies where the log entries will be stored. Logging is crucial for tracking actions and diagnosing issues.
-
`PASSWORD_FILE_DIRECTORY`: defines the directory for storing user passwords securely.
-
`PASSWORD_FILE`: is the file where encrypted passwords will be saved.
-
`PASSWORD_ENCRYPTION_KEY`: is used to encrypt user passwords.
-
`USERS_FILE`: takes the first script argument, which should be the path to a file containing user data.
Next, create this file path and give them the right permission using the command below.
```
touch $LOG_FILE
mkdir -p /var/secure
chmod 700 /var/secure
touch $PASSWORD_FILE
chmod 600 $PASSWORD_FILE
```
Details of the command in the codeblock are:
`touch $LOG_FILE`
-
`touch`: This command is used to create an empty file or update the access and modification times of an existing file.
-
`$LOG_FILE`: This variable holds the path("/var/log/user_management.log") to the log file.
`mkdir -p /var/secure`
-
`mkdir`: This command is used to create directories.
-
`-p`: This option allows the creation of parent directories as needed. If the directory already exists, it will not return an error.
-
`/var/secure`: This is the directory path to be created.
`chmod 700 /var/secure`
-
`chmod`: This command is used to change the permissions of files or directories.
-
`700`: This permission setting means:
-
`7`: The owner has read, write, and execute permissions.
-
`0`: The group has no permissions.
-
`0`: Others have no permissions.
-
`/var/secure`: The directory whose permissions are being modified.
` chmod 600 $PASSWORD_FILE`
-
`chmod`: This command changes the permissions of a file.
-
`600`: This permission setting means:
-
`6`: The owner has read and write permissions.
-
`0`: The group has no permissions.
-
`0`: Others have no permissions.
**Checking for Sudo Privileges**
```
if [ "$(id -u)" != "0" ]; then
echo "This script must be run with sudo. Exiting..."
exit 1
fi
```
This code ensures the script runs with root privileges by checking if the Effective User ID (EUID) is zero. In Linux, an EUID of `0` corresponds to the root user. If the script is not executed with administrative rights, it exits with an error message. This is because the script will perform actions that require elevated privileges, such as creating users and groups, setting passwords, creating files, etc.
**Validating Arguments**
Next to ensure that the script is properly executed with an input file provided as an argument, this conditional check terminates the script if no argument is detected. Using `$#`to represent the number of arguments passed when executing the script, it validates whether no argument ($# equals zero) or more than one argument ($# is greater than or equal to 2) is given. If either condition is met, an error message is displayed, halting the script's execution.
```
if [ $# -eq 0 ]; then
echo "No file path provided."
echo "Usage: $0 <user-data-file-path>"
exit 1
fi
```
Also to verify if the provided file exists. If the file does not exist, the script exits with an error message.
```
if [ ! -e "$USERS_FILE" ]; then
echo "The provided user's data file does not exist: $USERS_FILE"
exit 1
fi
```
**Function Definitions**
Next to ensure reusability and modularity in your code, copy and paste the several utility functions to your code
**Check for Installed Package:**
```
is_package_installed() {
dpkg -s "$1" >/dev/null 2>&1
}
```
This function checks if a package is installed on your machine using `dpkg`. It suppresses output and returns a status code.
**Encrypt Password:**
```
encrypt_password() {
echo "$1" | openssl enc -aes-256-cbc -pbkdf2 -base64 -pass pass:"$2"
}
```
The commnad uses openssl to encrypt a password. The password is encrypted using `AES-256-CBC` and a provided encryption key.
**Set Bash as Default Shell:**
```
set_bash_default_shell() {
local user="$1"
sudo chsh -s /bin/bash "$user"
}
```
This function sets Bash as the default shell for the specified user.
**Installing Required Packages:**
To ensure you have the necessary packages to run the script, add the code-block
```
if ! is_package_installed openssl; then
echo "openssl is not installed. Installing..."
sudo apt-get update
sudo apt-get install -y openssl
fi
if ! is_package_installed pwgen; then
echo "pwgen is not installed. Installing..."
sudo apt-get update
sudo apt-get install -y pwgen
fi
```
with the command above you have defined variables for the file paths corresponding to the log file, password file, and input file. Additionally, you have ensured that the script is being executed with superuser privileges.
The subsequent step involves iterating through each line in the input text file, separating these lines by usernames and groups, and then using the Bash script to create the users and assign them to their respective groups.
To set up these users and groups, incorporate the following commands into your `create_users.sh` script:
```
for line in "${lines[@]}"; do
# Remove leading and trailing whitespaces
line=$(echo "$line" | xargs)
# Split line by ';' and store the second part
IFS=';' read -r user groups <<< "$line"
# Remove leading and trailing whitespaces from the second part
groups=$(echo "$groups" | xargs)
# Create a variable groupsArray that is an array from spliting the groups of each user
IFS=',' read -ra groupsArray <<< "$groups"
# Check if user exists
if id "$user" &>/dev/null; then
echo "User $user already exists. Skipping creation."
continue
fi
# Generate a 6-character password using pwgen
password=$(pwgen -sBv1 6 1)
# Encrypt the password before storing it
encrypted_password=$(encrypt_password "$password" "$PASSWORD_ENCRYPTION_KEY")
# Store the encrypted password in the file
echo "$user:$encrypted_password" >> "$PASSWORD_FILE"
# Create the user with the generated password
sudo useradd -m -p $(openssl passwd -6 "$password") "$user"
# Set Bash as the default shell
set_bash_default_shell "$user"
# loop over each group in the groups array
for group in "${groupsArray[@]}"; do
group=$(echo "$group" | xargs)
# Check if group exists, if not, create it
if ! grep -q "^$group:" /etc/group; then
sudo groupadd "$group"
echo "Created group $group"
fi
# Add user to the group
sudo usermod -aG "$group" "$user"
echo "Added $user to $group"
done
echo "User $user created and password stored securely"
done
```
The command above does the following:
**Iterating Through Lines in the File**
```
for line in "${lines[@]}"; do
```
This command initiates a loop that iterates over each line in the `lines` array. Each element of the array `lines`, representing a line from the input file, is processed one by one and assigned to the `line` variable.
**Removing Leading and Trailing Whitespace**
```
line=$(echo "$line" | xargs)
```
Here, `echo "$line" | xargs` removes any leading and trailing whitespace from the current line. This ensures that any extra spaces at the beginning or end of the line are trimmed off.
**Splitting the Line into User and Groups**
```
IFS=';' read -r user groups <<< "$line"
```
This line splits the `line `variable into two parts based on the ; delimiter. The first part is assigned to `user`, and the second part is assigned to` groups. IFS=';' `sets the Internal Field Separator to ;, which defines how the line is split.
**Trimming Whitespace from Groups**
```
groups=$(echo "$groups" | xargs)
```
This command removes any leading and trailing whitespace from the `groups `variable. This is necessary to ensure that the group names are clean and free from extra spaces.
**Splitting Groups into an Array**
```
IFS=',' read -ra groupsArray <<< "$groups"
```
Here, `IFS=','` sets the Internal Field Separator to `,`. The read `-ra` groupsArray splits the groups string into an array groupsArray based on commas, with each element representing a group.
**Checking if User Already Exists**
```
if id "$user" &>/dev/null; then
echo "User $user already exists. Skipping creation."
continue
fi
```
This block checks if a user with the given `user` name already exists. The `id "$user" &>/dev/null ` command attempts to fetch user details, and if successful (i.e., the user exists), it outputs nothing to `/dev/null`. If the user exists, a message is printed, and the `continue` command skips the rest of the loop for this user and moves to the next iteration.
**Generating a 6-Character Password**
```
password=$(pwgen -sBv1 6 1)
```
This command generates a secure, random 6-character password using the `pwgen ` tool. The `-s ` flag ensures a secure password, `-B ` avoids ambiguous characters, and -v1 specifies the length and quantity (1 password).
**Encrypting the Password**
```
encrypted_password=$(encrypt_password "$password" "$PASSWORD_ENCRYPTION_KEY")
```
This line calls the `encrypt_password` function to encrypt the generated password. The encrypted password is stored in the `encrypted_password `variable. The encryption key used is stored in the `PASSWORD_ENCRYPTION_KEY ` variable.
**Storing the Encrypted Password**
```
echo "$user:$encrypted_password" >> "$PASSWORD_FILE"
```
This command appends the username and encrypted password to the `PASSWORD_FILE.` The ` >>` operator ensures that the data is added to the end of the file without overwriting existing content.
**Creating the User with the Generated Password**
```
sudo useradd -m -p $(openssl passwd -6 "$password") "$user"
```
This line creates a new user with the username stored in user. The `-m` option creates the user's home directory. The password is hashed using `openssl passwd -6` with the generated password, ensuring it is securely stored.
**Setting Bash as the Default Shell**
```
set_bash_default_shell "$user"
```
This function call sets Bash as the default shell for the new user. The `set_bash_default_shell ` function is assumed to be defined elsewhere in the script to change the user's shell to Bash.
**Adding User to Specified Groups**
```
for group in "${groupsArray[@]}"; do
group=$(echo "$group" | xargs)
```
This loop iterates through each group in the groupsArray array. Each group is cleaned of leading and trailing whitespace.
**Checking and Creating Group if Necessary**
```
if ! grep -q "^$group:" /etc/group; then
sudo groupadd "$group"
echo "Created group $group"
fi
```
For each group, this block checks if the group exists in the `/etc/group` file. If not, the `groupadd ` command creates the group, and a confirmation message is printed.
**Adding User to the Group**
```
sudo usermod -aG "$group" "$user"
echo "Added $user to $group"
```
This command adds the user to the specified group using `usermod -aG`. The `-aG` option appends the user to the supplementary group without affecting membership in other groups. A message is printed confirming the addition.
With this, you’ve successfully developed a script that efficiently handles user and group management on your system. You can find the complete script on the [Github Repo](https://github.com/kalio007/auto-user-management)
### Verifying Script Functionality

Firstly, make your script executable, run the command below,
```
chmod +x create_users.sh
```
then, run the script,
```
./create_user.sh ./text_file.txt
```
## In Conclusion
This article details the procedure for automating the creation of users and groups through a script. It incorporates several assumptions and compromises to balance security with usability. As an administrator, you can now leverage this script to streamline user onboarding within your organisation.

1,912,682 | Boosting VS Code Productivity - Custom Labels for React Component Files | Ever felt like you're drowning in a sea of index.ts files? Trust me, I've been there. Working on a... | 0 | 2024-07-05T11:33:48 | https://vanenshi.com/blog/custom-labels-for-react-component-files | vscode, productivity, react |
Ever felt like you're drowning in a sea of `index.ts` files? Trust me, I've been there. Working on a massive React project, I found myself constantly lost in a maze of identical-looking files. But then I stumbled upon a game-changer: VS Code's custom labels feature. Let me tell you how it transformed my coding life.
## The Problem with `index.ts` Overload
Picture this: You're deep in the zone, juggling multiple components, when suddenly you need to find that one specific `index.ts` file. You open the search bar, and bam! A flood of indistinguishable results. Frustrating, right? That's exactly where I was until I discovered the magic of custom labels.
## Enter Custom Labels
So, what's the deal with these custom labels? In a nutshell, they're VS Code's way of letting you personalize how file names appear in your editor tabs and search bar. For us React devs drowning in `index.ts` files, it's like throwing us a lifeline.
## Setting Up Custom Labels Step by Step
### 1. Enable Custom Labels
First, you'll need to enable custom labels in your VS Code settings. Just add this line to your settings.json:
```json
"workbench.editor.customLabels.enabled": true
```
### 2. Define Patterns for `index.ts` Files
Now, here's where the real magic happens. Add this bit to tell VS Code to replace those generic `index.ts` names with their parent directory names:
```json
"workbench.editor.customLabels.patterns": {
"**/index.{ts,js,tsx,jsx}": "${dirname}"
}
```
### 3. Customize for Specific Directories
If you're like me and have a specific folder where all your components live, you can target just that directory:
```json
"workbench.editor.customLabels.patterns": {
"components/*/index.{ts,js,tsx,jsx}": "${dirname}"
}
```
## The Benefits of Custom Labels
1. **Increased Readability**: Instead of a sea of `index.tsx` tabs, you'll see "Button", "Header", and so on. It's like your editor suddenly learned to speak your language!
2. **Efficient Searching**: Searching for specific components became a breeze.
3. **Reduced Mental Load**: No more second-guessing which `index.ts` I was looking at.
So, fellow coders, if you're tired of playing "Where's Waldo?" with your `index.ts` files, give custom labels a shot. It's a small change that packs a big punch in your daily coding life. Trust me, your future self will thank you!

1,909,510 | Linux Automated User Creation - Bash Script | Automating User Creation and Management with a Bash Script Managing users and groups in a Linux... | 0 | 2024-07-03T15:17:31 | https://dev.to/jic/linux-automated-user-creation-bash-script-44hl | Automating User Creation and Management with a Bash Script
Managing users and groups in a Linux environment can be a time-consuming task, especially in larger organizations. Automating this process with a Bash script can save administrators valuable time and reduce the risk of errors. In this article, we'll walk through a script designed to automate the creation of users, assignment of groups, and logging of these actions. We will explain the reasoning behind each step to ensure a clear understanding of how the script functions.
**Script Overview**
The script performs the following tasks:
Generates a random password for each user.
Logs actions and errors.
Reads user and group data from an input file.
Creates users and assigns them to specified groups.
Stores user passwords in a secure file.
**Step-by-Step Explanation**
**Setting Absolute Paths for Files**
```
input_file="/hng/username.txt" # Update with correct path to username.txt
log_file="/var/log/user_management.log"
password_file="/var/secure/user_passwords.txt" # Update with correct secure location
```
We define the paths for the input file, log file, and password file. The input file contains the usernames and groups, the log file records the actions taken by the script, and the password file stores the generated passwords securely.
**Generating Random Passwords**
```
generate_password() {
local password_length=12
local password=$(head /dev/urandom | tr -dc A-Za-z0-9 | head -c $password_length)
echo "$password"
}
```
This function generates a random password of 12 characters using /dev/urandom, a secure random number generator. The password includes uppercase and lowercase letters and digits.
**Logging Messages**
```
log_message() {
local log_timestamp=$(date +'%Y-%m-%d %H:%M:%S')
echo "$log_timestamp - $1" >> "$log_file"
}
```
The log_message function appends a timestamped message to the log file. This helps track the script's actions and any issues that arise.
**Checking for the Input File**
```
if [ ! -f "$input_file" ]; then
log_message "Error: $input_file not found. Exiting script."
exit 1
fi
```
Before proceeding, the script checks if the input file exists. If not, it logs an error message and exits.
**Creating the Log File**
```
if [ ! -f "$log_file" ]; then
sudo touch "$log_file"
sudo chmod 644 "$log_file"
log_message "Log file created: $log_file"
fi
```
If the log file does not exist, the script creates it and sets the appropriate permissions. It then logs that the log file has been created.
**Creating the Password File****
```
if [ ! -f "$password_file" ]; then
sudo touch "$password_file"
sudo chmod 600 "$password_file"
sudo chown root:root "$password_file"
log_message "Password file created: $password_file"
fi
```
Similarly, the script creates the password file if it doesn't exist and sets strict permissions to ensure its security. It logs the creation of the password file.
**Clearing Existing Password File Content**
```
sudo truncate -s 0 "$password_file"
```
The script clears any existing content in the password file to ensure it only contains current data.
**Reading the Input File and Creating Users**
```
while IFS=';' read -r username groups; do
# Trim leading and trailing whitespace from username and groups
username=$(echo "$username" | tr -d '[:space:]')
groups=$(echo "$groups" | tr -d '[:space:]')
# Generate random password
password=$(generate_password)
# Create user with specified groups and set password
sudo useradd -m -s /bin/bash -G "$groups" "$username" >> "$log_file" 2>&1
echo "$username:$password" | sudo chpasswd >> "$log_file" 2>&1
if [ $? -eq 0 ]; then
log_message "User '$username' created with groups: $groups. Password stored in $password_file."
echo "$username,$password" | sudo tee -a "$password_file" > /dev/null
sudo chmod 600 "$password_file"
sudo chown root:root "$password_file"
else
log_message "Failed to create user '$username'."
fi
done < "$input_file"
```
The script reads each line of the input file, which contains usernames and groups separated by a semicolon. It trims any whitespace from the usernames and groups, generates a random password, and attempts to create the user with the specified groups. If the user is successfully created, the password is logged and stored securely. If not, an error message is logged.
**Final Log Message**
```
log_message "User creation process completed."
echo "User creation process completed. Check $log_file for details."
```
_Once all users have been processed, the script logs a completion message and informs the user to check the log file for details._
**Conclusion and Next Steps**
Automating user creation and management with Bash scripting not only streamlines administrative tasks but also enhances system security and operational efficiency in Linux environments. By understanding and customizing the script presented in this article, you can adapt it to meet specific organizational needs and scale your user management processes effectively.

1,912,673 | 🚀 Simplify Your Linux Process Killing with a Fuzzy Process Killer 🚀 | Are you tired of sifting through numerous processes to identify and terminate them by looking up... | 0 | 2024-07-05T11:23:01 | https://dev.to/cschindlbeck/simplify-your-linux-process-killing-with-a-fuzzy-process-killer-3icj | terminal, bash, zsh, linux | Are you tired of sifting through numerous processes to identify and terminate them by looking up their PIDs?
Use this lightweight script function that leverages the power of fzf (a command-line fuzzy finder) to streamline the process of identifying and killing processes. Quickly locate and kill processes without memorizing PIDs!
How does it work?
- Process Listing: It lists all running processes with their PIDs and command names.
- Fuzzy Search: You can then use fzf to quickly filter and find the process you're looking for.

It powers... | 0 | 2024-07-05T11:22:45 | https://dev.to/subham_behera/uncovering-hidden-gems-in-javascript-9bd | javascript, webdev, beginners, programming | JavaScript is one of the most versatile and widely used programming languages in the world. It powers everything from simple websites to complex web applications. While many developers are familiar with its core features, JavaScript also has a plethora of lesser-known, yet incredibly useful, features that can make your code more efficient, elegant, and fun to write. In this blog post, we will explore some of these hidden gems that can take your JavaScript skills to the next level.
## 1. The `??` Nullish Coalescing Operator
The nullish coalescing operator (`??`) is a relatively new addition to JavaScript, introduced in ECMAScript 2020. It provides a way to handle `null` or `undefined` values without falling back on other falsy values like `0` or an empty string.
### Example:
```javascript
const name = null;
const defaultName = "Guest";
console.log(name ?? defaultName); // Output: Guest
```
### Use Case:
This operator is particularly useful when you want to assign default values to variables that may be `null` or `undefined`, but you don't want to override other falsy values.
## 2. The `?.` Optional Chaining Operator
Optional chaining (`?.`) allows you to safely access deeply nested properties of an object without having to check each reference manually.
### Example:
```javascript
const user = {
profile: {
address: {
city: "New York"
}
}
};
console.log(user.profile?.address?.city); // Output: New York
console.log(user.profile?.contact?.email); // Output: undefined
```
### Use Case:
Optional chaining can save you from writing lengthy and error-prone conditional checks when accessing nested properties.
## 3. The `!!` Double Bang Operator
The double bang operator (`!!`) is a quick way to convert a value to its boolean equivalent.
### Example:
```javascript
const isAuthenticated = !!user; // Converts the truthiness of user to a boolean value
console.log(isAuthenticated); // Output: true or false
```
### Use Case:
This operator is handy for ensuring that a value is explicitly converted to `true` or `false` in a concise manner.
## 4. The `?.[]` Optional Chaining with Dynamic Keys
Optional chaining also works with dynamic keys, which can be extremely useful when dealing with objects with dynamic property names.
### Example:
```javascript
const user = {
settings: {
theme: "dark"
}
};
const key = "theme";
console.log(user.settings?.[key]); // Output: dark
console.log(user.settings?.[key]?.background); // Output: undefined
```
### Use Case:
This feature is useful when accessing properties with dynamic keys, ensuring you avoid runtime errors.
## 5. The `Object.fromEntries()` Method
The `Object.fromEntries()` method transforms a list of key-value pairs into an object, which is the inverse operation of `Object.entries()`.
### Example:
```javascript
const entries = [
['name', 'Alice'],
['age', 25]
];
const obj = Object.fromEntries(entries);
console.log(obj); // Output: { name: 'Alice', age: 25 }
```
### Use Case:
This method is great for converting data structures like maps or arrays of pairs into objects.
## 6. The `import()` Function for Dynamic Imports
The `import()` function allows you to dynamically load modules, which can be useful for code splitting and lazy loading in modern JavaScript applications.
### Example:
```javascript
import('./module.js')
.then(module => {
module.doSomething();
})
.catch(err => {
console.error('Error loading module:', err);
});
```
### Use Case:
Dynamic imports are perfect for improving performance by loading code only when it's needed.
## 7. The `Proxy` Object for Meta-Programming
The `Proxy` object enables you to create a proxy for another object, which can intercept and redefine fundamental operations for that object.
### Example:
```javascript
const target = {
message: "Hello, world!"
};
const handler = {
get: (obj, prop) => {
return prop in obj ? obj[prop] : "Property does not exist";
}
};
const proxy = new Proxy(target, handler);
console.log(proxy.message); // Output: Hello, world!
console.log(proxy.nonExistentProperty); // Output: Property does not exist
```
### Use Case:
Proxies are powerful for adding custom behavior to objects, such as validation, logging, or modifying property access.
## 8. The `Reflect` API
The `Reflect` API provides methods for interceptable JavaScript operations. It's used in conjunction with `Proxy` to perform default operations.
### Example:
```javascript
const target = {
message: "Hello, world!"
};
const handler = {
set: (obj, prop, value) => {
if (prop === "message" && typeof value !== "string") {
throw new TypeError("Message must be a string");
}
return Reflect.set(obj, prop, value);
}
};
const proxy = new Proxy(target, handler);
proxy.message = "Hi!"; // Works
proxy.message = 42; // Throws TypeError: Message must be a string
```
### Use Case:
The `Reflect` API is useful for default operations in proxy traps, making your code more readable and less error-prone.
## 9. Tagged Template Literals
Tagged template literals allow you to parse template literals with a function. This can be useful for creating custom string processing functions.
### Example:
```javascript
function highlight(strings, ...values) {
return strings.reduce((result, string, i) => {
return `${result}${string}<span class="highlight">${values[i] || ''}</span>`;
}, '');
}
const name = "JavaScript";
const sentence = highlight`Learning ${name} is fun!`;
console.log(sentence); // Output: Learning <span class="highlight">JavaScript</span> is fun!
```
### Use Case:
Tagged template literals are great for creating custom string formatting and processing functions.
## 10. The `Intl` Object for Internationalization
The `Intl` object provides language-sensitive string comparison, number formatting, and date and time formatting.
### Example:
```javascript
const date = new Date(Date.UTC(2020, 11, 20, 3, 0, 0));
const options = { weekday: 'long', year: 'numeric', month: 'long', day: 'numeric' };
console.log(new Intl.DateTimeFormat('en-US', options).format(date)); // Output: Sunday, December 20, 2020
console.log(new Intl.DateTimeFormat('de-DE', options).format(date)); // Output: Sonntag, 20. Dezember 2020
```
### Use Case:
The `Intl` object is invaluable for applications that need to support multiple languages and locales, providing consistent and accurate formatting.
## Conclusion
JavaScript is full of hidden features that can make your code more powerful, efficient, and elegant. From the nullish coalescing and optional chaining operators to dynamic imports and the `Intl` object, these lesser-known features offer a treasure trove of functionality for developers. By incorporating these gems into your coding toolkit, you can write more expressive, maintainable, and efficient JavaScript.

1,912,537 | Dependency Injection made simple. | Dependency Injection is an intimitating word. But actually the concept is quite simple. Dependency... | 27,962 | 2024-07-05T11:17:54 | https://dev.to/emanuelgustafzon/dependency-injection-made-simple-3d4c | javascript, csharp, interfaces, dependencyinjection | Dependency Injection is an intimitating word. But actually the concept is quite simple.
Dependency Injection is a way of handling `objects` that are `dependent` on `other objects`
We will make an implementation in `JavaScript` and then in `C# with interfaces.`
Let’s start with a simple example of an object being dependent of another object.
```
class DatabaseConnection {
connect() {
console.log("Connected to database");
}
}
class PostsRouter {
get() {
const db = new DatabaseConnection();
db.connect();
console.log("Posts retrieved");
}
}
const posts = new PostsRouter;
posts.get();
```
In the example above the posts router is dependent on the database connection.
BUT there is a problem here. Even though this solution works, it’s not flexible. The code is, as we say tightly coupled.
What if you have two different database connections? One for SQLite and one for MySQL? To change the connection object you need to change the code in the posts route.
That’s when dependency injection comes in.
Dependency injection is basically nothing more than `passing an object` into the `constructor` or `setter` of a `class` that depends on that object.
Let’s try that!
```
class SQLiteConnection {
connect() {
console.log("Connected to SQlite");
}
}
class MySqlConnection {
connect() {
console.log("Connected to MySQL");
}
}
class PostsRouter {
constructor(connection) {
this.connection = connection;
}
get() {
this.connection.connect();
console.log("Posts retrieved");
}
}
const mySql = new MySqlConnection;
const sqlite = new SQLiteConnection;
const mysqlPosts = new PostsRouter(mySql);
const sqlitePosts = new PostsRouter(sqlite);
mysqlPosts.get();
sqlitePosts.get();
```
You see! This makes the code more flexible. The connection object is decoupled from the posts object. You can pass any object to the constructor.
## Benefits
* The code is decoupled and easier to manage.
* The code is easier to test. You can create a mock object and pass it to the post router.
## Interfaces
You might have noticed that our implementation worked fine in JavaScript because we don’t need to think about types.
But many times we work with strongly typed languages like TypeScript, C# and Java.
So the issue is when we send the connection object into the posts object we need to define a type.
That’s why we need interfaces. Interfaces is like classes but there is no implementation of methods or properties it’s just the types.
Let’s implement an interface for the connection objects.
```
interface IDb {
public void connect();
}
```
This is the structure of the connection object. It has a public method called connect and it returns void and has no parameters.
Now the connection classes can inherit from IDb to enforce the same structure.
```
class SQLiteConnection : IDb {
public void connect() {
Console.WriteLine("Connected to SQlite");
}
}
class MySqlConnection : IDb {
public void connect() {
Console.WriteLine("Connected to MySQL");
}
}
```
It’s worth noticing, that a class can inherit multiple interfaces in most languages.
Now we can pass the connection objects in the constructor of the posts route object using IDb as the type.
```
class PostsRouter {
IDb _connection;
public PostsRouter(IDb connection) {
this._connection = connection;
}
public void get() {
this._connection.connect();
Console.WriteLine("Posts retrieved");
}
}
```
I hope this explanation made sense to you!
Here is the full example.
```
using System;
interface IDb {
public void connect();
}
class SQLiteConnection : IDb {
public void connect() {
Console.WriteLine("Connected to SQlite");
}
}
class MySqlConnection : IDb {
public void connect() {
Console.WriteLine("Connected to MySQL");
}
}
class PostsRouter {
IDb _connection;
public PostsRouter(IDb connection) {
this._connection = connection;
}
public void get() {
this._connection.connect();
Console.WriteLine("Posts retrieved");
}
}
class Program {
public static void Main (string[] args) {
IDb sqlConnection = new SQLiteConnection();
IDb mySqlConnection = new MySqlConnection();
PostsRouter posts = new PostsRouter(sqlConnection);
PostsRouter posts2 = new PostsRouter(mySqlConnection);
posts.get();
posts2.get();
}
}
```

This picturesque location could only be Malawi in Africa. However, the abundant sunshine isn't always a blessing. Prolonged dry spells can leave the land and crops parched. This was the reality for William Kamkwamba, a young boy growing up in a remote village in Malawi.**
William had an insatiable hunger for learning and found joy in books, even though English was not his first language. One picture in particular sparked his imagination: a moving illustration of a windmill. This vision planted a seed in his mind. What if he could harness wind power to produce energy, lighting up his village and raising hopes for its residents?
Fearless and determined, William scoured dumps for metal scraps, bicycle parts, and anything else that could help him bring his dream to life. Steeped in newly acquired literacy and a great deal of stubbornness, William assembled a windmill. These structures, built from repurposed materials, became symbols of hope and ingenuity.
William's story is truly inspirational, showcasing human creativity. Imagine what he could have achieved with today’s resources like [Artificial Intelligence (AI)](https://www.techdogs.com/category/ai), which can process vast amounts of information swiftly.
With AI, William’s wind power project could reach unprecedented heights. Here’s how:
- **Brainy Windmill Assistant**: AI could analyze air currents using sophisticated computational techniques, acting as William’s personal windwatcher. This intelligent helper could guide him on the most appropriate sites for maximum wind power, ensuring efficient electricity generation.
- **Power Up the Village**: AI could ensure that every house in the village is electrified. It could optimize the distribution of electricity produced by the windmills so that each resident benefits. No more darkness or discomfort while searching for something at night.
- **Windmill Whisperer**: Like cars, windmills require regular maintenance. AI could assist William by analyzing data and predicting necessary repairs. This would help him maintain the windmills efficiently, ensuring their longevity.
Furthermore, AI tools like user-friendly chatbots could help village dwellers regulate their power consumption and manage bill payments. This would make energy management simple and accessible, reducing chaos and confusion.
AI has the potential to enhance the tangible difference made by windmill construction, ensuring everyone gets clean energy. These are just a few ways AI could supercharge William’s legacy and revolutionize energy management in his village. William Kamkwamba’s story is a beacon of hope, a reminder of human potential when combined with modern technology.

1,912,657 | The Angular Advantage: Simplifying Development with Unidirectional Flow and Presentational Components | Simplifying Angular Applications: Unidirectional Data Flow and Presentational Components Building... | 0 | 2024-07-05T11:07:45 | https://dev.to/jsdevelopermano/the-angular-advantage-simplifying-development-with-unidirectional-flow-and-presentational-components-27g |
**Simplifying Angular Applications: Unidirectional Data Flow and Presentational Components**
Building complex Angular applications can lead to tangled logic and data management headaches. Traditional approaches often involve components manipulating data directly, making it difficult to track changes and maintain a consistent state. Here, we explore two key concepts that can significantly improve your Angular development experience: Unidirectional Data Flow and Presentational Components.
**Unidirectional Data Flow: A Streamlined Approach**
Imagine data flowing through your application like a river. Traditionally, this flow could be chaotic, with data changing hands between components in unpredictable ways. Unidirectional Data Flow introduces a clear path for this "river" of data. Here's how it works:
**User interacts:** A user clicks a button, selects an item, or submits a form.
Component dispatches action: The component responsible for handling the user interaction dispatches an action. Think of an action as a message containing information about the event.
**Store updates state:** A centralized store, managed by NgRx or a similar library, receives the action and updates the application state accordingly.
**Component retrieves data:** The component subscribes to a selector, a function that retrieves specific data slices from the updated state.
**Component updates UI:** Based on the retrieved data, the component updates the user interface (UI) to reflect the changes.
// actions.ts
export const increment = createAction('[Counter] Increment');
export const decrement = createAction('[Counter] Decrement');
// reducer.ts
const initialState = { count: 0 };
export const counterReducer = createReducer(
initialState,
on(increment, (state) => ({ count: state.count + 1 })),
on(decrement, (state) => ({ count: state.count - 1 }))
);
// counter.component.ts
@Component({
selector: 'app-counter',
template: `
<button (click)="dispatchIncrement()">Increment</button>
<button (click)="dispatchDecrement()">Decrement</button>
<p>Count: {{ count$ | async }}</p>
`,
})
export class CounterComponent {
count$ = this.store.select(selectCount);
constructor(private store: Store<AppState>) {}
dispatchIncrement() {
this.store.dispatch(increment());
}
dispatchDecrement() {
this.store.dispatch(decrement());
}
}
This unidirectional flow offers several advantages:
**Predictability:** Since data flows in a single direction, it's easier to understand how changes in one part of the application affect others.
**Debugging:** With a clear path, debugging becomes simpler as you can pinpoint where data manipulations occur.
**Testability:** Unidirectional flow makes components easier to test in isolation, as they rely solely on actions and selectors for data.
**Components as Presentational Layers:** Keeping it Clean
Imagine your components as display cases in a museum. Their primary purpose is to showcase information, not manipulate it directly. By adopting the "presentational component" approach, you achieve this goal:
**Components focus on presentation:** These components handle user interactions and display data, but they don't modify the application state themselves.
Separation of concerns: This separation keeps your code organized and easier to maintain.
**Reusable components:** Presentational components often become reusable across different parts of your application since they don't rely on application-specific logic.
The Synergy of Unidirectional Data Flow and Presentational Components
// user-card.component.ts
@Component({
selector: 'app-user-card',
template: `
<div *ngIf="user">
<h2>{{ user.name }}</h2>
<p>Email: {{ user.email }}</p>
</div>
`,
})
export class UserCardComponent {
@Input() user: User | null = null;
}
Combining these two concepts creates a powerful development approach. Unidirectional data flow ensures predictable state management, while presentational components keep the logic clean and focused. This synergy leads to maintainable, testable, and scalable Angular applications.
**Ready to Streamline Your Development?**
Unidirectional data flow and presentational components represent a paradigm shift in Angular development. By embracing these strategies, you can build more robust and manageable applications, allowing you to focus on what matters most - delivering an exceptional user experience.
**Why Unidirectional Data Flow with NgRx Wins for Large-Scale Angular Applications**
While traditional two-way data binding and service layers with event emitters have their merits, for large-scale Angular applications, unidirectional data flow with NgRx offers several advantages:
**1. Improved Scalability and Maintainability:**
**Complexity Management:** Two-way data binding can become a tangled mess in large applications, making it difficult to track data flow and identify issues. NgRx provides a centralized store, simplifying state management and reducing the risk of bugs.
**Predictable Changes:** Unidirectional data flow ensures predictable state updates, making it easier to reason about how changes in one part of the application affect others. This becomes crucial as the application grows and components become more interconnected.
**2. Enhanced Testability:**
**Isolated Testing:** Components in a unidirectional flow architecture rely solely on actions and selectors to interact with the state. This allows for easier unit testing of components in isolation, as you don't need to mock complex data interactions.
**Debugging Benefits:** Since data changes follow a clear path, debugging becomes more efficient. You can pinpoint where state updates occur and identify the root cause of issues.
**3. Better Performance and Data Consistency:**
**Immutable State:** NgRx promotes immutability, meaning the state store never gets mutated directly. This improves performance and ensures data consistency across the application.
**Performance Optimizations:** NgRx offers features like memoization for selectors, which can improve performance by caching frequently used data slices.
**4. Developer Experience and Team Collaboration:**
**Clear Communication:** Unidirectional data flow fosters a clear understanding of how data flows within the application. This improves communication and collaboration within development teams.
**Reusable Patterns:** NgRx promotes well-defined patterns for actions, reducers, and selectors, making code more reusable and maintainable across different parts of the application.
While service layers with event emitters offer some benefits, they can still lead to complex data flows and tight coupling between components. Unidirectional data flow with NgRx provides a structured and scalable approach to managing application state, especially for large-scale Angular applications. | jsdevelopermano |

Have you ever started watching an online video tutorial and, in the middle of that video, the tutorial becomes boring for you? Or you always tell yourself that this time you’re going to finish an online course, but when you sit down and start learning, it feels like any other tedious task like washing dishes and laundry. And at the end, you find it impossible to stay productive and make progress.
The question is: **“How can I stay motivated when learning to code?”**
That’s when **Atomic Habits** by **James Clear** comes in. If you haven’t heard about this book, you probably aren’t into self-improvement books by any chance. In this book, **James Clear** answers questions like, What is a habit loop? How do I prime my environment to make progress on my goals? and How do I use Dopamine spikes to stick to good habits?
By answering these questions, I will show you how you can build the revolutionary habit of learning programming.
Let’s delve in…
...
Imagine a plane taking off from Los Angeles for New York. Just before takeoff, the pilot changes the flight path by **3.5 degrees**, which is trivial. It is such a small change that nobody in the place can notice anything. When the plane lands, the passengers find themselves doing a sniff test because they are walking on the clean streets of Washington, DC, instead of New York. The point is that very small changes can entirely change the trajectory of our lives. And just like the passengers, we do not see the immediate results of these changes, but in the long run, the combined effect of these tiny changes and the final outcome can be significantly different.
As a novice programmer, you would think that you need to build something revolutionary to make it into the tech industry, but in reality, all you need to do is take small steps toward your goal everyday and you will be there before you even know it.
If you keep scrolling Instagram or watching YouTube, you will be no better programmer than today in one year. Build tiny atomic habits that help you learn programming everyday and you’ll be very close to landing that Software Engineer job in one year, beyond the shadow of a doubt.
Building habits is easy, but sticking to them is where most programmers struggle and can’t stay consistent. When you start to learn programming, you expect to see a linear improvement, but here is what actually happens:
At the beginning, you’ll not see any results. James Clear calls this part of the graph “The valley of disappointment”. This is where most people lose motivation, give up, and go back to their old habits. But in reality, the returns for your efforts are actually delayed. Once you pass this “Disappointment phase”, you’ll feel like a superhuman. Learning a new programming language, building projects, and getting into various jobs will suddenly come naturally to you. And when you look back at the first piece of code you wrote, you’ll definitely laugh at yourself.

## Building Habit
To build a habit, you first need to understand the concepts of the “Habit Loop”. The habit loop contains Cue, Craving, Response, and Reward. That’s the loop that builds any good or bad habit that we repeat over and over again.
Let’s understand the Habit Loop by illustrating a bad habit we all suffer from. Your phone is next to you and vibrates (Cue), you crave to see who the notification is from (Craving), you pick up the phone (Response), you spend at least 30 minutes scrolling Instagram (Reward).
Or imagine that you feel bored with the video tutorial (Cue), you want to see something entertaining (Crave), you pick up the phone (Response), you watched entertaining MrBeast videos for another hour (Reward).
Soon, your brain starts making connections between watching YouTube and getting bored with the tutorial. And you end up building the bad habit of wasting time during your programming sessions.
The same way you can use the same Habit Loop to build decent habits, you can use your own laptop as a Cue to learn programming. James Clear mentions this in his book: You should make your Cue obvious by placing it where it catches your eye every time.
Cue alone cannot be sufficient; you also need to use **Implementation Intentions** to your advantage. **Studies have shown that the main reason most people don’t stick to good habits is not because they lack motivation but because they don’t have clarity about what they want to achieve.** When you say “Tomorrow, I will learn programming”, it’s just a stupid dream that has no clarity. So, instead of just saying that, use the **Habit Stacking** methodology. Next time you decide to learn programming, don’t just say, “I want to learn programming.” Instead, stack it with another task, like, just after brushing my teeth, I’ll sit down and write code for 2 straight hours. This powerful process is called habit stacking.
## The 2 Minute Rule
To build the habit of programming sufficiently, the 2-Minute Rule will get you there. When you set unrealistic goals for yourself, it becomes tough to stay motivated to work on them.
> _Make habit building easy by taking small steps every day._ — James Clear
James Clear recommends starting with only two minutes a day. For example, if you want to build the habit of reading books, you can start by reading for just 2 minutes a day and gradually increase the number of minutes in the process.
The same goes with the programming, you’ll NOT become an expert programmer overnight. Instead of watching the entire 40+ hour course in 2 days, try to get the most out of it by watching a single video of it and then implementing what you’ve learned. By doing so, you’ll prevent frustration and build a long-term habit of learning new things efficiently.

1,912,649 | WatchYourPorts - self-hosted ports inventory | I'm using a lot of self-hosted apps, both at work and in my homelab. Of course, I can't remember all... | 0 | 2024-07-05T10:57:20 | https://dev.to/aceberg/watchyourports-self-hosted-ports-inventory-55ek | showdev, go, network | I'm using a lot of self-hosted apps, both at work and in my homelab. Of course, I can't remember all ports taken by those apps. So, the idea of ports inventory seems reasonable.
**Why**
_Why not just use Portainer or other Docker tool?_
- Not all apps are hosted in `Docker`. Some things must be run as `systemd` services.
- Port may be exposed in `Docker`, but blocked by firewall.
- There may be ports exposed to the world, you are not aware of.
_So, the purposes of WatchYourPorts are:_
1. Inventory
2. Security
3. Monitoring
Monitoring is the last one, because it's not the main purpose of this app. There are already tools for that. `WatchYourPorts` can do simple port scan on timer and export data to `InfluxDB2/Grafana`.
**Details**
- No DB, all config is stored in two `yaml` files.
- All configuration can be done through `ENV` variables, `yaml` or `GUI`.
- `Docker` images for `arm/v6`,`arm/v7`,`arm/arm64`.
- Binary [releases](https://github.com/aceberg/WatchYourPorts/releases) for many platforms.
- Export to `InfluxDB2`, which allows building a `Grafana` dashboard.
- Simple [API](https://github.com/aceberg/watchyourports#api) to get data from `WatchYourPorts`.
**How**
Full installation guide is available in the [README](https://github.com/aceberg/WatchYourPorts) file. The easiest way to try it:
```sh
docker run --name wyp \
-e "TZ=$YourTimeZone" \
-v ~/.dockerdata/WatchYourPorts:/data/WatchYourPorts \
-p 8853:8853 \

### The Role of LLVMpipe in Enhancing GUI Rendering in Virtualized Environments
In the realm of virtualized environments, where direct access to GPU resources can often be limited or non-existent, the importance of efficient software rendering solutions cannot be overstated. One such solution that has gained significant traction is LLVMpipe, a Gallium3D driver designed to utilize the CPU for rendering tasks. This essay explores the benefits and implications of using LLVMpipe for rendering in virtualized environments, shedding light on its operational mechanics and advantages.
#### Understanding LLVMpipe
LLVMpipe is a part of the Gallium3D framework, a flexible and modular architecture for 3D graphics drivers in the Mesa 3D Graphics Library. Unlike traditional graphics drivers that rely on the GPU to handle rendering tasks, LLVMpipe leverages the CPU. This software-based rasterizer translates rendering commands into CPU instructions, which are then executed to produce the desired graphical output. The use of the LLVM (Low-Level Virtual Machine) compiler infrastructure enables LLVMpipe to generate highly optimized machine code tailored to the specific CPU architecture, thereby enhancing performance.
#### Benefits of LLVMpipe in Virtualized Environments
1. **Accessibility and Compatibility**:
In many virtualized environments, direct access to physical GPU resources is either restricted or entirely unavailable. This limitation can hinder the performance of graphically intensive applications. LLVMpipe provides a viable alternative by using the CPU for rendering, ensuring that graphical applications can run smoothly even in the absence of a dedicated GPU. This broadens the range of environments where advanced graphics applications can be deployed.
2. **Performance Optimization**:
Although CPUs are generally less efficient than GPUs at handling parallelized rendering tasks, LLVMpipe mitigates this disadvantage through the use of LLVM's powerful optimization capabilities. By generating machine code that is finely tuned to the specific CPU, LLVMpipe can achieve respectable performance levels. This is particularly beneficial in environments where modern multi-core CPUs are available, as LLVMpipe can distribute rendering tasks across multiple cores.
3. **Enhanced Resource Utilization**:
Virtualized environments often involve multiple virtual machines (VMs) running concurrently on a single physical host. By offloading rendering tasks to the CPU, LLVMpipe allows for better distribution of computational workloads. This can lead to more balanced resource utilization across the host system, preventing any single resource (such as the GPU) from becoming a bottleneck.
4. **Ease of Deployment**:
Implementing GPU pass-through or virtual GPU solutions in a virtualized environment can be complex and hardware-dependent. In contrast, deploying LLVMpipe is straightforward, requiring no special hardware or intricate configuration. This ease of deployment makes it an attractive option for environments where simplicity and reliability are paramount.
#### Practical Applications of LLVMpipe
The practical applications of LLVMpipe extend across various domains:
- **Remote Desktop Services**:
Virtual desktop infrastructure (VDI) solutions can benefit greatly from LLVMpipe. Users accessing graphical desktops remotely can experience improved performance and responsiveness, as rendering tasks are efficiently handled by the server's CPU.
- **Testing and Development**:
Developers working on graphical applications can use LLVMpipe to test their software in environments where direct GPU access is unavailable. This ensures that their applications are robust and capable of running in a variety of deployment scenarios.
- **Cloud Computing**:
In cloud environments, where instances are often virtualized and GPU resources may be shared among multiple users, LLVMpipe offers a way to provide consistent graphical performance without relying on dedicated GPU hardware.
#### Conclusion
LLVMpipe stands as a testament to the ingenuity of software-based solutions in overcoming hardware limitations. By harnessing the power of the CPU for rendering tasks, LLVMpipe opens up new possibilities for graphical applications in virtualized environments. Its accessibility, performance optimization, and ease of deployment make it an invaluable tool for ensuring smooth and efficient GUI rendering where GPU resources are scarce. As virtualized environments continue to evolve and expand, the role of LLVMpipe in enhancing graphical performance is likely to become even more pronounced, underscoring the enduring relevance of software-driven innovation in the field of computer graphics.

1,912,632 | Binary Size in Go Applications: How to Use go-size-analyzer | In the Go community, the size of application binaries is always a hot topic. In the pursuit of... | 0 | 2024-07-05T10:43:06 | https://dev.to/zxilly/binary-size-in-go-applications-how-to-use-go-size-analyzer-hmn | go, programming, productivity, opensource | In the Go community, the size of application binaries is always a hot topic. In the pursuit of extreme performance, every byte counts. Go is known for its simplicity and efficiency, but as projects grow in size, so can the binaries. In this article, I will show you how to use [`go-size-analyzer`](https://github.com/Zxilly/go-size-analyzer) and how to interpret the results.
## Installation
The project is hosted on GitHub. You can visit [https://github.com/Zxilly/go-size-analyzer](https://github.com/Zxilly/go-size-analyzer) to read the full documentation.
`go-size-analyzer` provides precompiled versions which you can download from [GitHub Release](https://github.com/Zxilly/go-size-analyzer/releases). It is also available through some package managers:
- **Homebrew** (MacOS/Linux):
```
brew install go-size-analyzer
```
- **Scoop** (Windows):
```
scoop install go-size-analyzer
```
- **Go Build and Install**:
```
go install github.com/Zxilly/go-size-analyzer/cmd/gsa@latest
```
The compiled version needs to download the required resource files from GitHub at runtime. These files are embedded in the precompiled versions.
## Usage
Run `gsa --version` to ensure `go-size-analyzer` is installed correctly.
Locate the binary you want to analyze. Here, we choose the Linux x86_64 version of CockroachDB.
```
gsa --web cockroach-linux-amd64
```
Wait for the command line to display:
Use your browser to visit `http://localhost:8080`, and you will see:
If this is your project, you can click on the package name on the left to see specific details. Is there a rarely used dependency taking up a lot of space? Has `embed` included extra files?
A simpler way is to check the sections on the right. We can see that the `.debug_*` segments take up a lot of space.
Using `go tool link --help` to view the specific parameters of Go's linker, we find:
```
-s disable symbol table
-strictdups int
sanity check duplicate symbol contents during object file reading (1=warn 2=err).
-tmpdir directory
use directory for temporary files
-v print link trace
-w disable DWARF generation
```
This means using the `-s -w` parameters can remove the `.symtab` and `.debug_*` segments, saving about `40M` of space in this binary.
To pass parameters to the linker during compilation, you can use the `-ldflags` parameter. The complete command would be `go build -ldflags="-s -w"`.
## Summary
In this article, we introduced how to use the `go-size-analyzer` tool to analyze the size of Go application binaries. This tool allows you to visualize the space occupied by different parts of your program and identify areas for optimization. We found that in many cases, the `.debug_*` segments take up a considerable amount of space, and using the `-s -w` parameters of the Go linker can significantly reduce the binary size.
If you find this tool helpful, consider visiting my GitHub repository at <https://github.com/Zxilly/go-size-analyzer> and giving it a star. Your support is very important to me, as it not only motivates me to continue improving this tool but also helps more people discover this useful resource. | zxilly |

Here's a basic implementation of user authentication features (Sign up, Login, Social Media Login, and Password Recovery) using React Native and Firebase. Firebase provides easy-to-use authentication services that integrate well with React Native.
### Step 1: Set Up Firebase
1. **Create a Firebase Project**
- Go to [Firebase Console](https://console.firebase.google.com/)
- Create a new project
- Add an Android/iOS app to your project and follow the setup instructions to get your configuration file (google-services.json for Android and GoogleService-Info.plist for iOS)
2. **Install Firebase in Your React Native Project**
```sh
npm install @react-native-firebase/app @react-native-firebase/auth
```
3. **Configure Firebase**
- For Android: Place `google-services.json` in `android/app/`
- For iOS: Place `GoogleService-Info.plist` in the `ios/` directory
### Step 2: Implement Authentication
#### Firebase Configuration
Create a `firebaseConfig.js` file to initialize Firebase:
```javascript
// src/firebaseConfig.js
import { firebase } from '@react-native-firebase/app';
import '@react-native-firebase/auth';
const firebaseConfig = {
apiKey: 'YOUR_API_KEY',
authDomain: 'YOUR_AUTH_DOMAIN',
projectId: 'YOUR_PROJECT_ID',
storageBucket: 'YOUR_STORAGE_BUCKET',
messagingSenderId: 'YOUR_MESSAGING_SENDER_ID',
appId: 'YOUR_APP_ID',
};
if (!firebase.apps.length) {
firebase.initializeApp(firebaseConfig);
}
export default firebase;
```
#### Sign Up
Create a `SignUpScreen.js` for user registration:
```javascript
// src/screens/SignUpScreen.js
import React, { useState } from 'react';
import { View, TextInput, Button, Text } from 'react-native';
import firebase from '../firebaseConfig';
const SignUpScreen = ({ navigation }) => {
const [email, setEmail] = useState('');
const [password, setPassword] = useState('');
const [error, setError] = useState('');
const handleSignUp = async () => {
try {
await firebase.auth().createUserWithEmailAndPassword(email, password);
navigation.navigate('Login');
} catch (error) {
setError(error.message);
}
};
return (
<View>
<TextInput
placeholder="Email"
value={email}
onChangeText={setEmail}
autoCapitalize="none"
/>
<TextInput
placeholder="Password"
value={password}
onChangeText={setPassword}
secureTextEntry
/>
{error ? <Text>{error}</Text> : null}
<Button title="Sign Up" onPress={handleSignUp} />
</View>
);
};
export default SignUpScreen;
```
#### Login
Create a `LoginScreen.js` for user login:
```javascript
// src/screens/LoginScreen.js
import React, { useState } from 'react';
import { View, TextInput, Button, Text } from 'react-native';
import firebase from '../firebaseConfig';
const LoginScreen = ({ navigation }) => {
const [email, setEmail] = useState('');
const [password, setPassword] = useState('');
const [error, setError] = useState('');
const handleLogin = async () => {
try {
await firebase.auth().signInWithEmailAndPassword(email, password);
navigation.navigate('Home');
} catch (error) {
setError(error.message);
}
};
return (
<View>
<TextInput
placeholder="Email"
value={email}
onChangeText={setEmail}
autoCapitalize="none"
/>
<TextInput
placeholder="Password"
value={password}
onChangeText={setPassword}
secureTextEntry
/>
{error ? <Text>{error}</Text> : null}
<Button title="Login" onPress={handleLogin} />
</View>
);
};
export default LoginScreen;
```
#### Password Recovery
Create a `PasswordRecoveryScreen.js` for password recovery:
```javascript
// src/screens/PasswordRecoveryScreen.js
import React, { useState } from 'react';
import { View, TextInput, Button, Text } from 'react-native';
import firebase from '../firebaseConfig';
const PasswordRecoveryScreen = ({ navigation }) => {
const [email, setEmail] = useState('');
const [message, setMessage] = useState('');
const handlePasswordReset = async () => {
try {
await firebase.auth().sendPasswordResetEmail(email);
setMessage('Password reset email sent!');
} catch (error) {
setMessage(error.message);
}
};
return (
<View>
<TextInput
placeholder="Email"
value={email}
onChangeText={setEmail}
autoCapitalize="none"
/>
<Button title="Reset Password" onPress={handlePasswordReset} />
{message ? <Text>{message}</Text> : null}
</View>
);
};
export default PasswordRecoveryScreen;
```
#### Social Media Login
Set up social media login using OAuth. Here, I'll demonstrate Google login.
1. **Install Required Packages**
```sh
npm install @react-native-google-signin/google-signin
```
2. **Configure Google Sign-In**
Create a `GoogleSignInConfig.js` file to configure Google Sign-In:
```javascript
// src/GoogleSignInConfig.js
import { GoogleSignin } from '@react-native-google-signin/google-signin';
GoogleSignin.configure({
webClientId: 'YOUR_WEB_CLIENT_ID.apps.googleusercontent.com', // From Firebase Console
offlineAccess: false,
});
export default GoogleSignin;
```
3. **Google Login Implementation**
Update your `LoginScreen.js` to include Google login:
```javascript
// src/screens/LoginScreen.js
import React, { useState } from 'react';
import { View, TextInput, Button, Text } from 'react-native';
import firebase from '../firebaseConfig';
import GoogleSignInConfig from '../GoogleSignInConfig';
import { GoogleSignin, statusCodes } from '@react-native-google-signin/google-signin';
const LoginScreen = ({ navigation }) => {
const [email, setEmail] = useState('');
const [password, setPassword] = useState('');
const [error, setError] = useState('');
const handleLogin = async () => {
try {
await firebase.auth().signInWithEmailAndPassword(email, password);
navigation.navigate('Home');
} catch (error) {
setError(error.message);
}
};
const handleGoogleLogin = async () => {
try {
await GoogleSignin.hasPlayServices();
const { idToken } = await GoogleSignin.signIn();
const googleCredential = firebase.auth.GoogleAuthProvider.credential(idToken);
await firebase.auth().signInWithCredential(googleCredential);
navigation.navigate('Home');
} catch (error) {
if (error.code === statusCodes.SIGN_IN_CANCELLED) {
setError('User cancelled the login flow');
} else if (error.code === statusCodes.IN_PROGRESS) {
setError('Signin in progress');
} else if (error.code === statusCodes.PLAY_SERVICES_NOT_AVAILABLE) {
setError('Play services not available or outdated');
} else {
setError(error.message);
}
}
};
return (
<View>
<TextInput
placeholder="Email"
value={email}
onChangeText={setEmail}
autoCapitalize="none"
/>
<TextInput
placeholder="Password"
value={password}
onChangeText={setPassword}
secureTextEntry
/>
{error ? <Text>{error}</Text> : null}
<Button title="Login" onPress={handleLogin} />
<Button title="Login with Google" onPress={handleGoogleLogin} />
</View>
);
};
export default LoginScreen;
```
### Navigation Setup
Make sure you have React Navigation set up to handle screen transitions. Here's an example `App.js`:
```javascript
// App.js
import React from 'react';
import { NavigationContainer } from '@react-navigation/native';
import { createStackNavigator } from '@react-navigation/stack';
import SignUpScreen from './src/screens/SignUpScreen';
import LoginScreen from './src/screens/LoginScreen';
import PasswordRecoveryScreen from './src/screens/PasswordRecoveryScreen';
import HomeScreen from './src/screens/HomeScreen';
const Stack = createStackNavigator();
const App = () => {
return (
<NavigationContainer>
<Stack.Navigator initialRouteName="Login">
<Stack.Screen name="SignUp" component={SignUpScreen} />
<Stack.Screen name="Login" component={LoginScreen} />
<Stack.Screen name="PasswordRecovery" component={PasswordRecoveryScreen} />
<Stack.Screen name="Home" component={HomeScreen} />
</Stack.Navigator>
</NavigationContainer>
);
};
export default App;
```
### Final Steps
- Make sure you have set up the SHA-1 key for Android in the Firebase Console for Google Sign-In.
- Configure your iOS and Android projects according to Firebase and Google Sign-In documentation.
This is a basic implementation of user authentication using Firebase in a React Native app. You can expand upon this by adding more features and improving error handling and user experience.
Implementing flight search and flight details functionalities requires integrating with a flight data provider API. For this example, we'll use a hypothetical flight API. You can adapt this to any real API by following their documentation.
### Step 1: Set Up API Integration
Create a service to handle API requests.
#### FlightService.js
```javascript
// src/services/FlightService.js
import axios from 'axios';
const API_BASE_URL = 'https://api.example.com'; // Replace with actual API URL
const searchFlights = async (params) => {
try {
const response = await axios.get(`${API_BASE_URL}/flights/search`, { params });
return response.data;
} catch (error) {
console.error(error);
throw error;
}
};
export { searchFlights };
```
### Step 2: Implement Flight Search
Create a screen to handle flight search.
#### FlightSearchScreen.js
```javascript
// src/screens/FlightSearchScreen.js
import React, { useState } from 'react';
import { View, TextInput, Button, Text, FlatList, TouchableOpacity } from 'react-native';
import { searchFlights } from '../services/FlightService';
const FlightSearchScreen = ({ navigation }) => {
const [from, setFrom] = useState('');
const [to, setTo] = useState('');
const [date, setDate] = useState('');
const [flights, setFlights] = useState([]);
const [error, setError] = useState('');
const handleSearch = async () => {
try {
const results = await searchFlights({ from, to, date });
setFlights(results);
} catch (error) {
setError('Error fetching flights');
}
};
const renderFlightItem = ({ item }) => (
<TouchableOpacity onPress={() => navigation.navigate('FlightDetails', { flight: item })}>
<View>
<Text>{item.airline}</Text>
<Text>{item.departure_time} - {item.arrival_time}</Text>
<Text>{item.price}</Text>
</View>
</TouchableOpacity>
);
return (
<View>
<TextInput placeholder="From" value={from} onChangeText={setFrom} />
<TextInput placeholder="To" value={to} onChangeText={setTo} />
<TextInput placeholder="Date" value={date} onChangeText={setDate} />
<Button title="Search Flights" onPress={handleSearch} />
{error ? <Text>{error}</Text> : null}
<FlatList
data={flights}
keyExtractor={(item) => item.id}
renderItem={renderFlightItem}
/>
</View>
);
};
export default FlightSearchScreen;
```
### Step 3: Implement Flight Details
Create a screen to display flight details.
#### FlightDetailsScreen.js
```javascript
// src/screens/FlightDetailsScreen.js
import React from 'react';
import { View, Text } from 'react-native';
const FlightDetailsScreen = ({ route }) => {
const { flight } = route.params;
return (
<View>
<Text>Airline: {flight.airline}</Text>
<Text>Departure Time: {flight.departure_time}</Text>
<Text>Arrival Time: {flight.arrival_time}</Text>
<Text>Duration: {flight.duration}</Text>
<Text>Price: {flight.price}</Text>
<Text>Stops: {flight.stops}</Text>
<Text>Baggage Policy: {flight.baggage_policy}</Text>
</View>
);
};
export default FlightDetailsScreen;
```
### Step 4: Navigation Setup
Update your `App.js` to include the new screens.
#### App.js
```javascript
// App.js
import React from 'react';
import { NavigationContainer } from '@react-navigation/native';
import { createStackNavigator } from '@react-navigation/stack';
import FlightSearchScreen from './src/screens/FlightSearchScreen';
import FlightDetailsScreen from './src/screens/FlightDetailsScreen';
const Stack = createStackNavigator();
const App = () => {
return (
<NavigationContainer>
<Stack.Navigator initialRouteName="FlightSearch">
<Stack.Screen name="FlightSearch" component={FlightSearchScreen} />
<Stack.Screen name="FlightDetails" component={FlightDetailsScreen} />
</Stack.Navigator>
</NavigationContainer>
);
};
export default App;
```
### Advanced Search Options
For advanced search options (multi-city, flexible dates), you can extend the `FlightSearchScreen` to include additional input fields and logic for handling those parameters.
#### FlightSearchScreen.js (Extended)
```javascript
// src/screens/FlightSearchScreen.js
import React, { useState } from 'react';
import { View, TextInput, Button, Text, FlatList, TouchableOpacity } from 'react-native';
import { searchFlights } from '../services/FlightService';
const FlightSearchScreen = ({ navigation }) => {
const [from, setFrom] = useState('');
const [to, setTo] = useState('');
const [date, setDate] = useState('');
const [multiCity, setMultiCity] = useState(false);
const [secondLegFrom, setSecondLegFrom] = useState('');
const [secondLegTo, setSecondLegTo] = useState('');
const [secondLegDate, setSecondLegDate] = useState('');
const [flights, setFlights] = useState([]);
const [error, setError] = useState('');
const handleSearch = async () => {
try {
const params = multiCity
? { from, to, date, secondLegFrom, secondLegTo, secondLegDate }
: { from, to, date };
const results = await searchFlights(params);
setFlights(results);
} catch (error) {
setError('Error fetching flights');
}
};
const renderFlightItem = ({ item }) => (
<TouchableOpacity onPress={() => navigation.navigate('FlightDetails', { flight: item })}>
<View>
<Text>{item.airline}</Text>
<Text>{item.departure_time} - {item.arrival_time}</Text>
<Text>{item.price}</Text>
</View>
</TouchableOpacity>
);
return (
<View>
<TextInput placeholder="From" value={from} onChangeText={setFrom} />
<TextInput placeholder="To" value={to} onChangeText={setTo} />
<TextInput placeholder="Date" value={date} onChangeText={setDate} />
{multiCity && (
<>
<TextInput placeholder="Second Leg From" value={secondLegFrom} onChangeText={setSecondLegFrom} />
<TextInput placeholder="Second Leg To" value={secondLegTo} onChangeText={setSecondLegTo} />
<TextInput placeholder="Second Leg Date" value={secondLegDate} onChangeText={setSecondLegDate} />
</>
)}
<Button title="Multi-City" onPress={() => setMultiCity(!multiCity)} />
<Button title="Search Flights" onPress={handleSearch} />
{error ? <Text>{error}</Text> : null}
<FlatList
data={flights}
keyExtractor={(item) => item.id}
renderItem={renderFlightItem}
/>
</View>
);
};
export default FlightSearchScreen;
```
This setup provides a basic structure for searching and displaying flight details in a React Native app. You can further customize it based on your specific requirements and the API documentation you are working with.
Integrating booking and payment functionality involves several steps, including seat selection, adding extras, integrating a payment gateway, and managing payment history and receipts. Here's a step-by-step guide to implement these features:
### Step 1: Set Up API Integration
Create a service to handle booking-related API requests.
#### BookingService.js
```javascript
// src/services/BookingService.js
import axios from 'axios';
const API_BASE_URL = 'https://api.example.com'; // Replace with actual API URL
const selectSeats = async (bookingId, seats) => {
try {
const response = await axios.post(`${API_BASE_URL}/bookings/${bookingId}/seats`, { seats });
return response.data;
} catch (error) {
console.error(error);
throw error;
}
};
const addAddons = async (bookingId, addons) => {
try {
const response = await axios.post(`${API_BASE_URL}/bookings/${bookingId}/addons`, { addons });
return response.data;
} catch (error) {
console.error(error);
throw error;
}
};
const makePayment = async (bookingId, paymentDetails) => {
try {
const response = await axios.post(`${API_BASE_URL}/bookings/${bookingId}/payment`, { paymentDetails });
return response.data;
} catch (error) {
console.error(error);
throw error;
}
};
const getPaymentHistory = async (userId) => {
try {
const response = await axios.get(`${API_BASE_URL}/users/${userId}/payments`);
return response.data;
} catch (error) {
console.error(error);
throw error;
}
};
export { selectSeats, addAddons, makePayment, getPaymentHistory };
```
### Step 2: Implement Booking Screen
Create a screen for selecting seats and adding add-ons.
#### BookingScreen.js
```javascript
// src/screens/BookingScreen.js
import React, { useState } from 'react';
import { View, Text, Button, FlatList, TouchableOpacity } from 'react-native';
import { selectSeats, addAddons } from '../services/BookingService';
const BookingScreen = ({ route, navigation }) => {
const { bookingId } = route.params;
const [seats, setSeats] = useState([]);
const [addons, setAddons] = useState([]);
const [error, setError] = useState('');
const handleSeatSelection = async (selectedSeats) => {
try {
const response = await selectSeats(bookingId, selectedSeats);
setSeats(response.seats);
} catch (error) {
setError('Error selecting seats');
}
};
const handleAddonsSelection = async (selectedAddons) => {
try {
const response = await addAddons(bookingId, selectedAddons);
setAddons(response.addons);
} catch (error) {
setError('Error adding addons');
}
};
const renderSeatItem = ({ item }) => (
<TouchableOpacity onPress={() => handleSeatSelection([item])}>
<View>
<Text>{item.seatNumber}</Text>
</View>
</TouchableOpacity>
);
const renderAddonItem = ({ item }) => (
<TouchableOpacity onPress={() => handleAddonsSelection([item])}>
<View>
<Text>{item.name}</Text>
</View>
</TouchableOpacity>
);
return (
<View>
<Text>Select Seats</Text>
<FlatList
data={/* Fetch seat data */}
keyExtractor={(item) => item.id}
renderItem={renderSeatItem}
/>
<Text>Select Add-ons</Text>
<FlatList
data={/* Fetch addons data */}
keyExtractor={(item) => item.id}
renderItem={renderAddonItem}
/>
{error ? <Text>{error}</Text> : null}
<Button title="Proceed to Payment" onPress={() => navigation.navigate('Payment', { bookingId })} />
</View>
);
};
export default BookingScreen;
```
### Step 3: Implement Payment Screen
Integrate a payment gateway (e.g., Stripe or PayPal). For this example, we'll use a mock payment integration.
#### PaymentScreen.js
```javascript
// src/screens/PaymentScreen.js
import React, { useState } from 'react';
import { View, TextInput, Button, Text } from 'react-native';
import { makePayment } from '../services/BookingService';
const PaymentScreen = ({ route, navigation }) => {
const { bookingId } = route.params;
const [cardNumber, setCardNumber] = useState('');
const [expiryDate, setExpiryDate] = useState('');
const [cvv, setCvv] = useState('');
const [error, setError] = useState('');
const handlePayment = async () => {
try {
const paymentDetails = { cardNumber, expiryDate, cvv };
await makePayment(bookingId, paymentDetails);
navigation.navigate('PaymentHistory');
} catch (error) {
setError('Error processing payment');
}
};
return (
<View>
<TextInput placeholder="Card Number" value={cardNumber} onChangeText={setCardNumber} />
<TextInput placeholder="Expiry Date" value={expiryDate} onChangeText={setExpiryDate} />
<TextInput placeholder="CVV" value={cvv} onChangeText={setCvv} secureTextEntry />
{error ? <Text>{error}</Text> : null}
<Button title="Make Payment" onPress={handlePayment} />
</View>
);
};
export default PaymentScreen;
```
### Step 4: Implement Payment History Screen
Create a screen to display payment history.
#### PaymentHistoryScreen.js
```javascript
// src/screens/PaymentHistoryScreen.js
import React, { useEffect, useState } from 'react';
import { View, Text, FlatList } from 'react-native';
import { getPaymentHistory } from '../services/BookingService';
const PaymentHistoryScreen = ({ route }) => {
const { userId } = route.params;
const [payments, setPayments] = useState([]);
const [error, setError] = useState('');
useEffect(() => {
const fetchPaymentHistory = async () => {
try {
const paymentHistory = await getPaymentHistory(userId);
setPayments(paymentHistory);
} catch (error) {
setError('Error fetching payment history');
}
};
fetchPaymentHistory();
}, [userId]);
const renderPaymentItem = ({ item }) => (
<View>
<Text>Payment ID: {item.id}</Text>
<Text>Amount: {item.amount}</Text>
<Text>Date: {item.date}</Text>
</View>
);
return (
<View>
{error ? <Text>{error}</Text> : null}
<FlatList
data={payments}
keyExtractor={(item) => item.id}
renderItem={renderPaymentItem}
/>
</View>
);
};
export default PaymentHistoryScreen;
```
### Navigation Setup
Update your `App.js` to include the new screens.
#### App.js
```javascript
// App.js
import React from 'react';
import { NavigationContainer } from '@react-navigation/native';
import { createStackNavigator } from '@react-navigation/stack';
import BookingScreen from './src/screens/BookingScreen';
import PaymentScreen from './src/screens/PaymentScreen';
import PaymentHistoryScreen from './src/screens/PaymentHistoryScreen';
import FlightSearchScreen from './src/screens/FlightSearchScreen';
import FlightDetailsScreen from './src/screens/FlightDetailsScreen';
const Stack = createStackNavigator();
const App = () => {
return (
<NavigationContainer>

);
};
export default App;
```
This setup provides a basic structure for booking flights, selecting seats, adding add-ons, making payments, and viewing payment history in a React Native app.
Implementing user profile management and notifications involves several steps. Let's break it down into manageable parts.
### User Profile Management
1. **View and Edit Profile Details**
2. **Save Payment Methods**
3. **View Booking History**
4. **Manage Saved Preferences**
### Step 1: Set Up API Integration
Create a service to handle user profile-related API requests.
#### UserService.js
```javascript
// src/services/UserService.js
import axios from 'axios';
const API_BASE_URL = 'https://api.example.com'; // Replace with actual API URL
const getUserProfile = async (userId) => {
try {
const response = await axios.get(`${API_BASE_URL}/users/${userId}`);
return response.data;
} catch (error) {
console.error(error);
throw error;
}
};
const updateUserProfile = async (userId, profileData) => {
try {
const response = await axios.put(`${API_BASE_URL}/users/${userId}`, profileData);
return response.data;
} catch (error) {
console.error(error);
throw error;
}
};
const savePaymentMethod = async (userId, paymentMethod) => {
try {
const response = await axios.post(`${API_BASE_URL}/users/${userId}/payment-methods`, paymentMethod);
return response.data;
} catch (error) {
console.error(error);
throw error;
}
};
const getBookingHistory = async (userId) => {
try {
const response = await axios.get(`${API_BASE_URL}/users/${userId}/bookings`);
return response.data;
} catch (error) {
console.error(error);
throw error;
}
};
const savePreferences = async (userId, preferences) => {
try {
const response = await axios.post(`${API_BASE_URL}/users/${userId}/preferences`, preferences);
return response.data;
} catch (error) {
console.error(error);
throw error;
}
};
export { getUserProfile, updateUserProfile, savePaymentMethod, getBookingHistory, savePreferences };
```
### Step 2: Implement User Profile Screen
#### UserProfileScreen.js
```javascript
// src/screens/UserProfileScreen.js
import React, { useEffect, useState } from 'react';
import { View, TextInput, Button, Text } from 'react-native';
import { getUserProfile, updateUserProfile, savePreferences } from '../services/UserService';
const UserProfileScreen = ({ route }) => {
const { userId } = route.params;
const [profile, setProfile] = useState({});
const [preferences, setPreferences] = useState({});
const [error, setError] = useState('');
useEffect(() => {
const fetchUserProfile = async () => {
try {
const userProfile = await getUserProfile(userId);
setProfile(userProfile);
} catch (error) {
setError('Error fetching profile');
}
};
fetchUserProfile();
}, [userId]);
const handleUpdateProfile = async () => {
try {
await updateUserProfile(userId, profile);
} catch (error) {
setError('Error updating profile');
}
};
const handleSavePreferences = async () => {
try {
await savePreferences(userId, preferences);
} catch (error) {
setError('Error saving preferences');
}
};
return (
<View>
<TextInput
placeholder="Name"
value={profile.name || ''}
onChangeText={(text) => setProfile({ ...profile, name: text })}
/>
<TextInput
placeholder="Email"
value={profile.email || ''}
onChangeText={(text) => setProfile({ ...profile, email: text })}
/>
<TextInput
placeholder="Preferred Airlines"
value={preferences.preferredAirlines || ''}
onChangeText={(text) => setPreferences({ ...preferences, preferredAirlines: text })}
/>
<TextInput
placeholder="Seating Preferences"
value={preferences.seatingPreferences || ''}
onChangeText={(text) => setPreferences({ ...preferences, seatingPreferences: text })}
/>
{error ? <Text>{error}</Text> : null}
<Button title="Update Profile" onPress={handleUpdateProfile} />
<Button title="Save Preferences" onPress={handleSavePreferences} />
</View>
);
};
export default UserProfileScreen;
```
### Step 3: Implement Payment Methods Screen
#### PaymentMethodsScreen.js
```javascript
// src/screens/PaymentMethodsScreen.js
import React, { useState } from 'react';
import { View, TextInput, Button, Text } from 'react-native';
import { savePaymentMethod } from '../services/UserService';
const PaymentMethodsScreen = ({ route }) => {
const { userId } = route.params;
const [cardNumber, setCardNumber] = useState('');
const [expiryDate, setExpiryDate] = useState('');
const [cvv, setCvv] = useState('');
const [error, setError] = useState('');
const handleSavePaymentMethod = async () => {
try {
const paymentMethod = { cardNumber, expiryDate, cvv };
await savePaymentMethod(userId, paymentMethod);
} catch (error) {
setError('Error saving payment method');
}
};
return (
<View>
<TextInput placeholder="Card Number" value={cardNumber} onChangeText={setCardNumber} />
<TextInput placeholder="Expiry Date" value={expiryDate} onChangeText={setExpiryDate} />
<TextInput placeholder="CVV" value={cvv} onChangeText={setCvv} secureTextEntry />
{error ? <Text>{error}</Text> : null}
<Button title="Save Payment Method" onPress={handleSavePaymentMethod} />
</View>
);
};
export default PaymentMethodsScreen;
```
### Step 4: Implement Booking History Screen
#### BookingHistoryScreen.js
```javascript
// src/screens/BookingHistoryScreen.js
import React, { useEffect, useState } from 'react';
import { View, Text, FlatList } from 'react-native';
import { getBookingHistory } from '../services/UserService';
const BookingHistoryScreen = ({ route }) => {
const { userId } = route.params;
const [bookings, setBookings] = useState([]);
const [error, setError] = useState('');
useEffect(() => {
const fetchBookingHistory = async () => {
try {
const bookingHistory = await getBookingHistory(userId);
setBookings(bookingHistory);
} catch (error) {
setError('Error fetching booking history');
}
};
fetchBookingHistory();
}, [userId]);
const renderBookingItem = ({ item }) => (
<View>
<Text>Booking ID: {item.id}</Text>
<Text>Flight: {item.flightNumber}</Text>
<Text>Date: {item.date}</Text>
<Text>Amount: {item.amount}</Text>
</View>
);
return (
<View>
{error ? <Text>{error}</Text> : null}
<FlatList
data={bookings}
keyExtractor={(item) => item.id}
renderItem={renderBookingItem}
/>
</View>
);
};
export default BookingHistoryScreen;
```
### Step 5: Implement Notifications
Implementing notifications involves setting up push notifications and email notifications.
#### Setup Push Notifications
Use libraries like `react-native-push-notification` for push notifications.
#### Setup Email Notifications
Integrate with an email service provider (e.g., SendGrid) to send email notifications.
### Navigation Setup
Update your `App.js` to include the new screens.
#### App.js
```javascript
// App.js
import React from 'react';
import { NavigationContainer } from '@react-navigation/native';
import { createStackNavigator } from '@react-navigation/stack';
import UserProfileScreen from './src/screens/UserProfileScreen';
import PaymentMethodsScreen from './src/screens/PaymentMethodsScreen';
import BookingHistoryScreen from './src/screens/BookingHistoryScreen';
import FlightSearchScreen from './src/screens/FlightSearchScreen';
import FlightDetailsScreen from './src/screens/FlightDetailsScreen';
import BookingScreen from './src/screens/BookingScreen';
import PaymentScreen from './src/screens/PaymentScreen';
import PaymentHistoryScreen from './src/screens/PaymentHistoryScreen';
const Stack = createStackNavigator();
const App = () => {
return (
<NavigationContainer>
<Stack.Navigator initialRouteName="FlightSearch">
<Stack.Screen name="FlightSearch" component={FlightSearchScreen} />
<Stack.Screen name="FlightDetails" component={FlightDetailsScreen} />
<Stack.Screen name="Booking" component={BookingScreen} />
<Stack.Screen name="Payment" component={PaymentScreen} />
<Stack.Screen name="PaymentHistory" component={PaymentHistoryScreen} />
<Stack.Screen name="UserProfile" component={UserProfileScreen} />
<Stack.Screen name="PaymentMethods" component={PaymentMethodsScreen} />
<Stack.Screen name="BookingHistory" component={BookingHistoryScreen} />
</Stack.Navigator>
</NavigationContainer>
);
};
export default App;
```
This setup provides a basic structure for managing user profiles, payment methods, booking history, and notifications in a React Native app.
To implement flight status tracking and customer support in your React Native app, you'll need to integrate APIs for real-time flight status updates and a service for in-app chat support. Let's go through the steps to implement these features.
### Flight Status Tracking
#### Step 1: Set Up API Integration
Create a service to handle flight status-related API requests.
#### FlightStatusService.js
```javascript
// src/services/FlightStatusService.js
import axios from 'axios';
const API_BASE_URL = 'https://api.flightstatus.com'; // Replace with actual API URL
const getFlightStatus = async (flightNumber) => {
try {
const response = await axios.get(`${API_BASE_URL}/flights/${flightNumber}/status`);
return response.data;
} catch (error) {
console.error(error);
throw error;
}
};
export { getFlightStatus };
```
#### Step 2: Implement Flight Status Screen
Create a screen to display real-time flight status updates.
#### FlightStatusScreen.js
```javascript
// src/screens/FlightStatusScreen.js
import React, { useState } from 'react';
import { View, TextInput, Button, Text } from 'react-native';
import { getFlightStatus } from '../services/FlightStatusService';
const FlightStatusScreen = () => {
const [flightNumber, setFlightNumber] = useState('');
const [flightStatus, setFlightStatus] = useState(null);
const [error, setError] = useState('');
const handleCheckStatus = async () => {
try {
const status = await getFlightStatus(flightNumber);
setFlightStatus(status);
} catch (error) {
setError('Error fetching flight status');
}
};
return (
<View>
<TextInput
placeholder="Enter Flight Number"
value={flightNumber}
onChangeText={setFlightNumber}
/>
<Button title="Check Status" onPress={handleCheckStatus} />
{error ? <Text>{error}</Text> : null}
{flightStatus ? (
<View>
<Text>Flight Number: {flightStatus.flightNumber}</Text>
<Text>Status: {flightStatus.status}</Text>
<Text>Departure Time: {flightStatus.departureTime}</Text>
<Text>Arrival Time: {flightStatus.arrivalTime}</Text>
</View>
) : null}
</View>
);
};
export default FlightStatusScreen;
```
### Notifications for Flight Status
Use a service like Firebase Cloud Messaging (FCM) for push notifications. This requires setting up FCM in your React Native app.
#### Setting Up FCM (Brief Overview)
1. **Install the necessary packages**:
```bash
npm install @react-native-firebase/app @react-native-firebase/messaging
```
2. **Configure Firebase**:
Follow the instructions on the [React Native Firebase documentation](https://rnfirebase.io/) to set up Firebase in your app.
3. **Handle Notifications**:
```javascript
// App.js
import messaging from '@react-native-firebase/messaging';
useEffect(() => {
const unsubscribe = messaging().onMessage(async remoteMessage => {
Alert.alert('A new FCM message arrived!', JSON.stringify(remoteMessage));
});
return unsubscribe;
}, []);
```
### Customer Support
#### Step 1: Integrate In-App Chat Support
Use a service like Firebase Firestore for in-app chat or a third-party service like Zendesk or Intercom.
#### InAppChatService.js (using Firebase Firestore)
```javascript
// src/services/InAppChatService.js
import firestore from '@react-native-firebase/firestore';
const sendMessage = async (chatId, message) => {
try {
await firestore().collection('chats').doc(chatId).collection('messages').add({
text: message,
createdAt: firestore.FieldValue.serverTimestamp(),
});
} catch (error) {
console.error(error);
throw error;
}
};
const getMessages = (chatId, callback) => {
return firestore().collection('chats').doc(chatId).collection('messages')
.orderBy('createdAt', 'desc')
.onSnapshot(callback);
};
export { sendMessage, getMessages };
```
#### Step 2: Implement Chat Screen
Create a screen for in-app chat support.
#### ChatScreen.js
```javascript
// src/screens/ChatScreen.js
import React, { useEffect, useState } from 'react';
import { View, TextInput, Button, FlatList, Text } from 'react-native';
import { sendMessage, getMessages } from '../services/InAppChatService';
const ChatScreen = ({ route }) => {
const { chatId } = route.params;
const [message, setMessage] = useState('');
const [messages, setMessages] = useState([]);
useEffect(() => {
const unsubscribe = getMessages(chatId, (snapshot) => {
const fetchedMessages = snapshot.docs.map(doc => ({ id: doc.id, ...doc.data() }));
setMessages(fetchedMessages);
});
return () => unsubscribe();
}, [chatId]);
const handleSend = async () => {
try {
await sendMessage(chatId, message);
setMessage('');
} catch (error) {
console.error('Error sending message:', error);
}
};
const renderMessage = ({ item }) => (
<View>
<Text>{item.text}</Text>
<Text>{item.createdAt?.toDate().toLocaleString()}</Text>
</View>
);
return (
<View>
<FlatList
data={messages}
keyExtractor={(item) => item.id}
renderItem={renderMessage}
/>
<TextInput
placeholder="Type your message"
value={message}
onChangeText={setMessage}
/>
<Button title="Send" onPress={handleSend} />
</View>
);
};
export default ChatScreen;
```
### Step 3: Customer Service Contact Information
#### CustomerServiceScreen.js
```javascript
// src/screens/CustomerServiceScreen.js
import React from 'react';
import { View, Text } from 'react-native';
const CustomerServiceScreen = () => {
return (
<View>
<Text>Customer Service</Text>
<Text>Email: [email protected]</Text>
<Text>Phone: +1 (800) 123-4567</Text>
</View>
);
};
export default CustomerServiceScreen;
```
### Navigation Setup
Update your `App.js` to include the new screens.
#### App.js
```javascript
// App.js
import React from 'react';
import { NavigationContainer } from '@react-navigation/native';
import { createStackNavigator } from '@react-navigation/stack';
import UserProfileScreen from './src/screens/UserProfileScreen';
import PaymentMethodsScreen from './src/screens/PaymentMethodsScreen';
import BookingHistoryScreen from './src/screens/BookingHistoryScreen';
import FlightSearchScreen from './src/screens/FlightSearchScreen';
import FlightDetailsScreen from './src/screens/FlightDetailsScreen';
import BookingScreen from './src/screens/BookingScreen';
import PaymentScreen from './src/screens/PaymentScreen';
import PaymentHistoryScreen from './src/screens/PaymentHistoryScreen';
import FlightStatusScreen from './src/screens/FlightStatusScreen';
import ChatScreen from './src/screens/ChatScreen';
import CustomerServiceScreen from './src/screens/CustomerServiceScreen';
const Stack = createStackNavigator();
const App = () => {
return (
<NavigationContainer>
<Stack.Navigator initialRouteName="FlightSearch">
<Stack.Screen name="FlightSearch" component={FlightSearchScreen} />
<Stack.Screen name="FlightDetails" component={FlightDetailsScreen} />
<Stack.Screen name="Booking" component={BookingScreen} />
<Stack.Screen name="Payment" component={PaymentScreen} />

Implementing multi-language support, currency conversion, weather forecasts, and offline access in your React Native app requires various integrations and configurations. Let's go through each feature step-by-step.
### Multi-language Support
#### Step 1: Install and Configure i18n
1. **Install `react-i18next` and `i18next`**:
```bash
npm install react-i18next i18next
npm install @react-native-async-storage/async-storage
```
2. **Create `i18n.js`**:
```javascript
// src/i18n.js
import i18n from 'i18next';
import { initReactI18next } from 'react-i18next';
import AsyncStorage from '@react-native-async-storage/async-storage';
import en from './locales/en.json';
import es from './locales/es.json';
const languageDetector = {
type: 'languageDetector',
async: true,
detect: async (callback) => {
const language = await AsyncStorage.getItem('user-language');
callback(language || 'en');
},
init: () => {},
cacheUserLanguage: async (language) => {
await AsyncStorage.setItem('user-language', language);
},
};
i18n
.use(languageDetector)
.use(initReactI18next)
.init({
fallbackLng: 'en',
resources: {
en: { translation: en },
es: { translation: es },
},
interpolation: {
escapeValue: false,
},
});
export default i18n;
```
3. **Create translation files** (`en.json`, `es.json`):
- `src/locales/en.json`:
```json
{
"welcome": "Welcome",
"search": "Search",
"flight_status": "Flight Status",
"profile": "Profile"
}
```
- `src/locales/es.json`:
```json
{
"welcome": "Bienvenido",
"search": "Buscar",
"flight_status": "Estado del vuelo",
"profile": "Perfil"
}
```
4. **Wrap your App with i18next Provider**:
```javascript
// App.js
import React from 'react';
import { NavigationContainer } from '@react-navigation/native';
import { createStackNavigator } from '@react-navigation/stack';
import { I18nextProvider } from 'react-i18next';
import i18n from './src/i18n';
import UserProfileScreen from './src/screens/UserProfileScreen';
import FlightSearchScreen from './src/screens/FlightSearchScreen';
// Other imports...
const Stack = createStackNavigator();
const App = () => {
return (
<I18nextProvider i18n={i18n}>
<NavigationContainer>
<Stack.Navigator initialRouteName="FlightSearch">
<Stack.Screen name="FlightSearch" component={FlightSearchScreen} />
<Stack.Screen name="UserProfile" component={UserProfileScreen} />
{/* Other screens */}
</Stack.Navigator>
</NavigationContainer>
</I18nextProvider>
);
};
export default App;
```
5. **Use Translations in Components**:
```javascript
// src/screens/FlightSearchScreen.js
import React from 'react';
import { View, Text } from 'react-native';
import { useTranslation } from 'react-i18next';
const FlightSearchScreen = () => {
const { t } = useTranslation();
return (
<View>
<Text>{t('welcome')}</Text>
<Text>{t('search')}</Text>
</View>
);
};
export default FlightSearchScreen;
```
### Currency Converter
#### Step 1: Set Up API Integration
Create a service to handle currency conversion-related API requests.
#### CurrencyService.js
```javascript
// src/services/CurrencyService.js
import axios from 'axios';
const API_BASE_URL = 'https://api.currencyapi.com'; // Replace with actual API URL
const getExchangeRate = async (baseCurrency, targetCurrency) => {
try {
const response = await axios.get(`${API_BASE_URL}/latest`, {
params: {
base: baseCurrency,
symbols: targetCurrency,
},
});
return response.data.rates[targetCurrency];
} catch (error) {
console.error(error);
throw error;
}
};
export { getExchangeRate };
```
#### Step 2: Implement Currency Converter
#### CurrencyConverter.js
```javascript
// src/components/CurrencyConverter.js
import React, { useState, useEffect } from 'react';
import { View, Text, TextInput, Picker, Button } from 'react-native';
import { getExchangeRate } from '../services/CurrencyService';
const CurrencyConverter = () => {
const [amount, setAmount] = useState('');
const [convertedAmount, setConvertedAmount] = useState('');
const [baseCurrency, setBaseCurrency] = useState('USD');
const [targetCurrency, setTargetCurrency] = useState('EUR');
const [error, setError] = useState('');
const handleConvert = async () => {
try {
const rate = await getExchangeRate(baseCurrency, targetCurrency);
setConvertedAmount((parseFloat(amount) * rate).toFixed(2));
} catch (error) {
setError('Error fetching exchange rate');
}
};
return (
<View>
<TextInput
placeholder="Amount"
keyboardType="numeric"
value={amount}
onChangeText={setAmount}
/>
<Picker selectedValue={baseCurrency} onValueChange={setBaseCurrency}>
<Picker.Item label="USD" value="USD" />
<Picker.Item label="EUR" value="EUR" />
{/* Add more currencies */}
</Picker>
<Picker selectedValue={targetCurrency} onValueChange={setTargetCurrency}>
<Picker.Item label="EUR" value="EUR" />
<Picker.Item label="USD" value="USD" />
{/* Add more currencies */}
</Picker>
<Button title="Convert" onPress={handleConvert} />
{error ? <Text>{error}</Text> : null}
{convertedAmount ? <Text>Converted Amount: {convertedAmount}</Text> : null}
</View>
);
};
export default CurrencyConverter;
```
### Weather Forecast
#### Step 1: Set Up API Integration
Create a service to handle weather-related API requests.
#### WeatherService.js
```javascript
// src/services/WeatherService.js
import axios from 'axios';

const getWeather = async (city) => {
try {
const response = await axios.get(`${API_BASE_URL}/current.json`, {
params: {
key: 'YOUR_API_KEY',
q: city,
},
});
return response.data;
} catch (error) {
console.error(error);
throw error;
}
};
export { getWeather };
```
#### Step 2: Implement Weather Forecast Component
#### WeatherForecast.js
```javascript
// src/components/WeatherForecast.js
import React, { useState, useEffect } from 'react';
import { View, Text, TextInput, Button } from 'react-native';
import { getWeather } from '../services/WeatherService';
const WeatherForecast = () => {
const [city, setCity] = useState('');
const [weather, setWeather] = useState(null);
const [error, setError] = useState('');
const handleGetWeather = async () => {
try {
const data = await getWeather(city);
setWeather(data);
} catch (error) {
setError('Error fetching weather data');
}
};
return (
<View>
<TextInput
placeholder="Enter City"
value={city}
onChangeText={setCity}
/>
<Button title="Get Weather" onPress={handleGetWeather} />
{error ? <Text>{error}</Text> : null}
{weather ? (
<View>
<Text>Temperature: {weather.current.temp_c}°C</Text>
<Text>Condition: {weather.current.condition.text}</Text>
</View>
) : null}
</View>
);
};
export default WeatherForecast;
```
### Offline Access

1. **Install `@react-native-async-storage/async-storage`**:
```bash
npm install @react-native-async-storage/async-storage
```
#### Step 2: Implement Offline Access for Booking Details
#### OfflineService.js
```javascript
// src/services/OfflineService.js
import AsyncStorage from '@react-native-async-storage/async-storage';
const saveBookingDetails = async (bookingDetails) => {
try {
await AsyncStorage.setItem('bookingDetails', JSON.stringify(bookingDetails));
} catch (error) {
console.error(error);
throw error;
}
};
const getBookingDetails = async () => {
try {
const bookingDetails = await AsyncStorage.getItem('bookingDetails');
return bookingDetails ? JSON.parse(bookingDetails) : null;
} catch (error) {
console.error(error);
throw error;
}
};
export { saveBookingDetails, getBookingDetails };
```
#### Step 3: Implement Offline Booking Details Screen

These lamps combine elegance, functionality, and a touch of retro flair, making them a perfect addition to any contemporary home. In this guide, we'll walk you through everything you need to know to choose the ideal mid-century arc floor lamp for your space.
## 1. Understanding Mid-Century Modern Design
Before diving into the specifics of arc floor lamps, it’s essential to understand the core principles of mid-century modern design:
Simplicity and Functionality: Clean lines, minimal ornamentation, and practical designs.
Integration with Nature: Use natural materials and seamless indoor-outdoor connections.
Organic Forms: Curved lines and asymmetrical shapes that evoke a natural flow.
Bold Use of Color: Pops of bright colors balanced with neutral tones.
## 2. What is an Arc Floor Lamp?
An arc floor lamp is characterized by its long, sweeping arm that extends outwards from a sturdy base, allowing the light to be positioned over a desired area without the need for a table or additional furniture. This design became popular in the mid-20th century and remains a staple in modern interiors.
## 3. Key Features to Consider
When choosing the perfect mid-century arc floor lamp, consider the following features:
### a. Size and Proportions
Height: Ensure the lamp is tall enough to provide overhead lighting without being obtrusive.
Reach: The arc should extend far enough to position the light where needed.
Base: A sturdy base is crucial for stability, especially for taller lamps.
### b. Materials and Finish
Metal: Common in mid-century designs, metals like brass, chrome, and steel offer durability and a sleek appearance.
Wood: Adds warmth and a natural element to the design.
Shade: Typically made from fabric, glass, or metal. Select a tint that goes well with your decor.
### c. Style and Design
Classic vs. Modern: Some arc lamps have a distinctly retro look, while others offer a more contemporary interpretation.
Color: Mid-century designs often feature bold colors. Consider how the lamp’s color will interact with your existing décor.
Details: Look for unique design elements such as exposed bulbs, adjustable arms, or intricate patterns.
## 4. Placement and Functionality
### a. Living Room
Arc floor lamps are ideal for providing overhead lighting in seating areas. Place it near a sofa or armchair to create a cozy reading nook or to highlight a coffee table.
### b. Dining Area
Use an arc lamp to illuminate a dining table, especially in spaces where ceiling lights are not practical. This can create an intimate and stylish dining experience.
### c. Home Office
An arc floor lamp can provide focused task lighting in a home office, helping to reduce eye strain and improve productivity.
## 5. Budget Considerations
Mid-century arc floor lamps come in a range of prices. Determine your budget beforehand and consider the following:
Vintage vs. Reproduction: Authentic vintage lamps may be more expensive but offer unique character. Reproductions can provide the same aesthetic at a lower cost.
Quality and Durability: Higher-priced lamps often feature better materials and construction, ensuring longevity.
## 6. Top Picks for Mid-Century Arc Floor Lamps
Here are some highly recommended mid-century arc floor lamps that combine style and functionality:
### a. Arco Lamp by Flos
An iconic design by Achille and Pier Giacomo Castiglioni, this lamp features a marble base and a stainless steel arc, epitomizing mid-century elegance.
### b. Brightech Sparq Arc LED Floor Lamp
A modern take on the classic design, this lamp offers a minimalist look with an energy-efficient LED light.
### c. Adesso Bowery Arc Lamp
With a sleek, brushed steel finish and a large fabric shade, this lamp blends seamlessly into contemporary interiors.
## 7. Maintenance Tips
To keep your mid-century arc floor lamp looking its best:
Regular Dusting: Prevents buildup on the lamp's surface and shade.
Check Connections: Ensure the electrical connections are secure and safe.
Polish Metal Parts: Use appropriate cleaners to maintain the shine of metal components.
## Conclusion
Choosing the perfect mid-century arc floor lamp involves considering size, materials, style, and placement. By understanding the principles of mid-century design and evaluating your specific needs, you can find a light that not only illuminates your space but also enhances your home's aesthetic. Whether you opt for a vintage classic or a modern reinterpretation, the right arc floor lamp can become a striking focal point in any room.

It... | 0 | 2024-07-05T10:30:37 | https://dev.to/traveltranquilitynepal/peak-climbing-in-nepal-finding-the-best-peaks-4hh2 | peakclimbinginnepal, nepal, peakclimbing, travel | Many adventure seekers dream of visiting Nepal, which is home to the breathtaking Himalayas. It provides unforgettable experiences, ranging from breathtaking scenery to difficult peak climbing. In this blog, I’ll offer some of Nepal’s top **_[climbing peaks](https://www.nepalsocialtreks.com/activities/mountain-expedition/peak-climbing/)_** as well as crucial suggestions to make your Himalayan experience unforgettable. I’ll also include some personal experiences along the road!
**Best Peaks to Climb in Nepal**
**1. Island Peak (Imja Tse)**
Island Peak is one of the most popular hiking destinations in Nepal. It lies at 6,189 meters (20,305 feet) and provides climbers with a breathtaking perspective of Everest and the surrounding peaks. I remember the first time I saw Island Peak; its pointy, snowy summit was both appealing and terrifying. The climb was tough but extremely rewarding.
**2. Mera Peak**
Mera Peak, at 6,476 meters (21,247 ft), is Nepal’s highest trekking peak. It’s ideal for individuals who want to try high-altitude climbing without any technical challenges. The summit offers panoramic views of five of the world’s highest mountains: Everest, Lhotse, Makalu, Cho Oyu, and Kanchenjunga. When I reached the summit of Mera Peak, I felt like I was on top of the world, surrounded by these towering giants.
**3. Lobuche East**
Lobuche East is another impressive summit, towering at 6,119 meters (20,075 ft). It is more difficult than Island and Mera Peaks because to the steeper slopes and rocky terrain. The hike to Lobuche East also passes through the stunning Khumbu region. My hike up Lobuche East was strenuous, but the breathtaking vistas of Everest, Lhotse, and Ama Dablam made every step worthwhile.
**Essential Tips for a Successful Climb**
**1. Physical Preparation**
Climbing in the Himalayas needs a high level of physical fitness. You can prepare by engaging in regular aerobic exercises, strength training, and backpacking. I spent months walking, cycling, and trekking to prepare my body for the challenges of high-altitude climbing.
**2. Acclimatization**
Acclimatization is critical to avoiding altitude sickness. Spend a few days at a lower altitude before moving up. I made sure to follow the golden rule: climb high and sleep low. This allowed my body to gradually adjust to the altitude.
**3. Hire a Guide**
A local guide can make a significant difference. They understand the topography and weather patterns and can help in an emergency. My guide, Pemba, was vital during my climbs, providing assistance, local knowledge, and a pleasant smile even during difficult circumstances.
**4. Pack Smart**
Packing the appropriate equipment is critical. Warm clothing, a nice sleeping bag, durable climbing boots, and a dependable backpack are essential. I also took snacks such as energy bars and dried fruits to keep my energy levels high.
**5. Stay Hydrated and Eat Well**
High altitudes can dehydrate you quickly, so drink plenty of water. Eating well is also important to keep your energy up. I found that drinking ginger tea and eating local meals helped me stay warm and energized.
**6. Respect the Environment**
The Himalayas are beautiful and fragile. Always follow the principles of Leave No Trace. Carry out all your trash, avoid disturbing wildlife, and respect local customs and traditions. During my climbs, I made it a point to minimize my impact and respect the pristine environment.
**Personal Experience: My First Peak Climb in Nepal**
Island Peak was my first climb in Nepal. The journey was difficult, with long days of trekking, freezing nights, and the struggle of thin air. But standing on the summit, gazing out at the sea of snow-capped peaks, I felt a profound sense of accomplishment. The splendor of the Himalayas, the camaraderie with other climbers, and the friendliness of the Nepalese people made it an unforgettable experience.
**Conclusion**
**_[Peak climbing](https://www.nepalsocialtreks.com/activities/mountain-expedition/peak-climbing/)_** in Nepal is a genuinely unique experience. Whether you are a seasoned climber or a beginner, the Himalayas have something for everyone. With the proper preparation, respect for the environment, and a little perseverance, you can conquer these spectacular peaks and make experiences that will last a lifetime. So lace up your boots, pack your backpack, and prepare for the adventure of a lifetime in Nepal! | traveltranquilitynepal |

Here are two common... | 0 | 2024-07-05T10:29:14 | https://dev.to/ndiaga/how-do-i-export-users-from-wordpress-4p6f | `Exporting users from WordPress can be done using plugins or through custom code. Here are two common methods:
Method 1: Using a Plugin
Plugins make the process simple and efficient, even for users with limited technical knowledge.
Recommended Plugin: "Export Users to CSV"
Install the Plugin
Go to your WordPress dashboard.
Navigate to Plugins > Add New.
Search for "Export Users to CSV."
Click Install Now and then Activate.
Export Users
After activating the plugin, go to Users > Export Users to CSV.
Configure the export options as needed (e.g., select user roles, fields to include, etc.).
Click the Export button to download the CSV file containing your user data.
Method 2: Using Custom Code
For more control over the export process, you can use custom code. This method requires access to your WordPress files and some knowledge of PHP.
Step-by-Step Guide
Add Custom Code to Your Theme
Add the following code to your theme’s functions.php file or a custom plugin:
php
Copier le code
function export_users_csv() {
if (isset($_GET['export_users'])) {
$args = array(
'role' => '',
'orderby' => 'user_nicename',
'order' => 'ASC'
);
$users = get_users($args);
$filename = "users_" . date("Y-m-d_H-i", time()) . ".csv";
header("Content-Type: text/csv");
header("Content-Disposition: attachment; filename=$filename");
header("Pragma: no-cache");
header("Expires: 0");
$output = fopen("php://output", "w");
// Column headers
fputcsv($output, array('ID', 'Username', 'Email', 'Display Name', 'First Name', 'Last Name'));
foreach ($users as $user) {
$user_info = array(
$user->ID,
$user->user_login,
$user->user_email,
$user->display_name,
$user->first_name,
$user->last_name
);
fputcsv($output, $user_info);
}
fclose($output);
exit();
}
}
add_action('admin_init', 'export_users_csv');
Trigger the Export
To export the users, add ?export_users=1 to the URL of your WordPress admin dashboard. For example: http://yourwebsite.com/wp-admin/?export_users=1.
This will trigger the export_users_csv function and download a CSV file containing your user data.
Conclusion
Exporting users from WordPress can be done quickly using plugins or custom code. Using the "Export Users to CSV" plugin is the easiest and most user-friendly method, while custom code provides more control and customization options. Choose the method that best suits your needs.
If you need more specialized tools or support for your PrestaShop integration, you can find helpful resources and modules at PrestaTuts.

1,912,613 | perf: private count vs #count | Which one is faster: private count or #count? If you are a JavaScript developer, you might have... | 0 | 2024-07-05T10:28:53 | https://puruvj.dev/blog/js-class-private-vs-ts-private | webdev, javascript, performance, typescript | Which one is faster: `private count` or `#count`?
If you are a JavaScript developer, you might have heard about the concept of private and public properties in JavaScript. JavaScript only had public properties until 2019, until Chrome shipped the [Private Class Fields](https://v8.dev/features/class-fields#private-class-fields) feature.
```ts
class Person {
#name: string;
age: number;
}
```
TypeScript has had public and private properties since forever:
```ts
class Person {
private name: string;
public age: number;
}
```
As you can see, it's not as compact as JS version, but it works well. But what are the differences between the two? How do TypeScript's private properties work?
# TypeScript lies
TypeScript lies to you. The private property is not actually private. **It's invisible, not inaccessible**. TypeScript will mark the property as private, but it can not prevent you from accessing it.
Input:
```ts
class Person {
private name: string;
public age: number;
constructor() {
this.name = 'Harry';
this.age = 17;
}
}
```
JS Output:
```js
'use strict';
class Person {
constructor() {
this.name = 'Harry';
this.age = 17;
}
}
```
Declaration(d.ts) output:
```ts
declare class Person {
private name;
age: number;
constructor();
}
```
There is nothing stopping anyone from accessing `person.name`. Sure there will be red squiggles in the editor, but it can be bypassed.
An excerpt from Harry Potter to understand it better:
> Snape’s eyes were fixed upon the door. His nostrils flared. He was walking slowly toward it, his wand held out in front of him like a weapon.
>
> “Potter,” he breathed, his eyes narrowing, “I know you’re here. You can’t hide forever.”
>
> Snape took another step forward, his free hand outstretched, fingers splayed, as though he could almost sense Harry’s presence through the cloak. Harry held his breath, trying to remain as silent and still as possible while Snape’s hand moved closer and closer, searching the air just inches from his face.
# What is the actual performance difference?
We know TypeScript lies. So what? There is no performance difference. Right? Right???
TLDR: There is no performance difference for ~~most~~ any practical use case. Literally none. Go use JS private properties(#count) over `private count` in TypeScript, it's more robust.
However if you wanna hang around to see how I reached that conclusion and when there **actually is** a performance difference, then you can read on.
## Setting up benchmark
We'll use an extremely simple benchmark to see the performance difference. Plain vanilla JS.
> How are you going to emulate TypeScript private properties in JS?
>
> Easy: TypeScript private properties are just JS public properties. In fact, I also lied to you. This post isn't a difference between `private count vs #count` in JS. It is a difference between public and private properties in JS. Plain and simple.
```ts
class Something {
#a = 1;
#b = 2;
a = 4;
b = 2;
constructor() {
const start_time = performance.now();
for (let i = 0; i < 1_000_000; i++) {
this.#a + this.#b;
}
console.log('Private:', performance.now() - start_time);
{
const start_time = performance.now();
for (let i = 0; i < 1_000_000; i++) {
this.a + this.b;
}
console.log('Public:', performance.now() - start_time);
}
}
}
```
Pretty simple, right? We're just creating a class with two public and two private properties, and then we're timing how long it takes to access them a million times.
Executing this is one line:
```ts
new Something();
```
And this is it. I pasted this directly into Chrome Devtools console, and it gives me this:
```txt
Private: 3.4000000059604645
Public: 2.300000011920929
```
So private property access is 1.47x slower than public property access. That's it. It may seem a lot but don't forget, we're accessing them a million times. If I run it for only 1000 times, then the output is this, most of the time:
```txt
Private: 0
Public: 0
```
It's so fast there's no difference calling it a thousand times, and in most prod apps it will be called just a few times.
### There's more: Caching
The above is the result on first run, means the class instance is created for the first time and Browser hasn't cached the class yet. But what if we run it a few more times and see how cache affects the result?
```ts
new Something(); // Repeat this line 10 times
new Something();
new Something();
new Something();
new Something();
new Something();
new Something();
new Something();
new Something();
new Something();
```
And this is the result:
```txt
Private: 3.7000000029802322
Public: 0.6000000089406967
Private: 0.7000000029802322
Public: 0.699999988079071
Private: 0.800000011920929
Public: 0.5
Private: 0.8999999910593033
Public: 0.5
Private: 0.7999999970197678
Public: 0.5999999940395355
Private: 0.7000000029802322
Public: 0.5999999940395355
Private: 0.7000000029802322
Public: 0.6000000089406967
Private: 0.5999999940395355
Public: 0.6000000089406967
Private: 0.7000000029802322
Public: 0.5
Private: 0.7000000029802322
Public: 0.5
```
The very first time, the browser cached public property access, making it almost 6.2x faster than (correspondingly) private property access. But the rest of the time, public properties are cached well enough such that there are multiple instances of `0.5`.
Private properties are always a bit slower even when cached, in fact most of the time its 1.4-1.5x slower, in line with uncached benchmark above.
I bet this is because browser has to keep track of checks for private properties to deny any external access to them. It's like building a backend. A backend may be cached really really well in Redis, but every request requires checking authentication adds some overhead.
# Conclusion
There is no performance difference for ~~most~~ any practical use case. Literally none. Go use JS private properties(#count) over `private count` in TypeScript, it's more robust.
Peace ☮️

Redis is an in memory data structure store often used as a cache and message broker but can as well be used as a primary database.
Redis is well suited for JWT authentication tokens due to Speed, Scalability, TTL(Time To Live), Session Storage.
I will use own repository to showcase how have I used it and if you want to follow video format you can check out bellow YouTube videos.
https://youtu.be/SQrsDZU_D5k
https://youtu.be/NissLXyZ2Zw
## Introduction
In JWT authentication like mine it makes sense if you have a primary database like PostgreSQL, Mongo or Firebase(like in my example).
Be sure to run command
`go get github.com/redis/go-redis/v9`
Ones installed figure out if you want to run Redis in a Docker Image or PaaS provider like Upstash👇
https://console.upstash.com/login
You can use Docker to run Redis.
> docker run - name recepie -p 6379:6379 -d redis:latest
In a nutshell my frontend is with React but backend is Go with Gin Web Framework main database Firebase and Redis will save userID with AuthToken ones logged in from frontend.
## Architecture & Code
Architecures change based on implementation This is how I have approached it to make it organized.
### Application Configuration
**LoadConfigurations:** Set up initial configurations, including connecting to Firebase and Redis.
```
func (a *Application) LoadConfigurations() error {
ctx := context.Background()
fireClient, err := GetFirestoreClient(ctx)
if err != nil {
return err
}
a.FireClient = fireClient
fireAuth, err := GetAuthClient(ctx)
if err != nil {
return err
}
a.FireAuth = fireAuth
// Redis env variable depending if PaaS server provided if not 6379 port used.
// So basically Docker image.
a.RedisPort = envy.Get("REDIS_SERVER", "localhost:6379")
redisClient, err := RedisConnect(a.RedisPort)
if err != nil {
return err
}
a.RedisClient = redisClient
a.ListenPort = envy.Get("PORT", "8080")
return nil
}
```
**RedisConnect Function:** Connect to Redis, handling both Docker and PaaS setups
```
func redisClientPort(port string, envExists bool) (*redis.Client, error) {
if envExists {
opt, err := redis.ParseURL(port)
if err != nil {
return nil, fmt.Errorf("failed to parse Redis URL: %w", err)
}
return redis.NewClient(opt), nil
}
return redis.NewClient(&redis.Options{
Addr: port,
Password: "",
DB: 0,
}), nil
}
func RedisConnect(port string) (*redis.Client, error) {
_, ok := os.LookupEnv(port)
client, err := redisClientPort(port, ok)
if err != nil {
return nil, fmt.Errorf("failed to ping Redis server: %w", err)
}
ping, err := client.Ping(context.Background()).Result()
if err != nil {
return nil, fmt.Errorf("failed to ping Redis server: %w", err)
}
fmt.Println("Ping response from Redis:", ping)
return client, nil
}
```
**Start Function:** Initialize the Gin router and set up routes and middleware.
```
func Start(a *app.Application) error {
router := gin.New()
router.Use(cors.New(md.CORSMiddleware()))
api.SetCache(router, a.RedisClient)
api.SetRoutes(router, a.FireClient, a.FireAuth, a.RedisClient)
err := router.Run(":" + a.ListenPort)
if err != nil {
return err
}
return nil
}
```
**SetCache Function:** Define endpoints for setting cache and other requests handled by **Firebase**.
```
// api/controller.go
func SetCache(router *gin.Engine, client *redis.Client) {
router.POST("/set-cache", func(c *gin.Context) {
setUserCache(c, client)
})
router.GET("/check-expiration", func(c *gin.Context) {
checkTokenExpiration(c, client)
})
}
func SetRoutes(router *gin.Engine, client *firestore.Client, auth *auth.Client, redisClient *redis.Client) {
router.OPTIONS("/*any", func(c *gin.Context) {
c.Status(http.StatusOK)
})
// In Gin Use means that it's required
router.Use(func(c *gin.Context) {
authToken := getUserCache(c, redisClient)
md.AuthJWT(auth, authToken)(c)
})
router.GET("/", func(c *gin.Context) {
showRecepies(c, client)
})
router.POST("/", func(c *gin.Context) {
addRecepie(c, client)
})
```
In SetRouters we do main requests to alter db data. **AuthJWT **is set by client side on **Firebase **to authenticate any request made to database.
AuthToken is what we will be talking about and it is passed in to AuthJWT to authenticate or deny user of any interaction.
---
Next up is to set up main GET, SET actions including TTL for session management.
```
// models/cache.go
type UserCache struct {
UserID string `redis:"UserID"`
AuthToken string `redis:"AuthToken"`
}
```
The above struct is the only important one to parse incoming data from React. ☝️
### Handling Cache Operations
**Get User Cache:** Retrieve user cache from Redis.
```
// api/cache.go
func getUserCache(ctx *gin.Context, client *redis.Client) string {
userID := ctx.Query("userID")
authToken, err := models.GetUserCacheToken(ctx, client, userID)
if err != nil {
log.Printf("Issues retriving Cached Token %v", err)
return ""
}
return authToken
}
// models/cache.go
func GetUserCacheToken(ctx *gin.Context, client *redis.Client, userID string) (string, error) {
key := fmt.Sprintf("user:%s", userID)
cache, err := client.HGetAll(ctx, key).Result()
if err != nil {
return "", fmt.Errorf("failed to get cache: %v", err)
}
authToken, ok := cache["AuthToken"]
if !ok {
return "", fmt.Errorf("AuthToken not found in cache")
}
return authToken, nil
}
```
**Set User Cache:** Set user cache in Redis with TTL.
```
// api/cache.go
func setUserCache(ctx *gin.Context, client *redis.Client) {
var userCache models.UserCache
err := models.UnmarshallRequestBodyToAPIData(ctx.Request.Body, &userCache)
if err != nil {
ctx.JSON(http.StatusBadRequest, gin.H{
"error": "Unable to parse data",
})
return
}
key := fmt.Sprintf("user:%s", userCache.UserID)
_, notExists := client.HGetAll(ctx, key).Result()
if notExists == nil {
userCache.SetCachedToken(ctx, client, key)
return
}
}
// models/cache.go
func (c *UserCache) SetCachedToken(ctx *gin.Context, client *redis.Client, key string) {
fields := map[string]interface{}{
"UserID": c.UserID,
"AuthToken": c.AuthToken,
}
err := client.HSet(ctx, key, fields).Err()
if err != nil {
log.Printf("Issues setting Cached Token %v", err)
}
client.Expire(ctx, key, 7*24*time.Hour)
}
```
> If you are interested in React section let me know otherwise Github repo will be listed bellow.
> As on React login through Firebase it creates a user with authToken and passes to Go backend if exists ignore otherwise create.
### Check Token Expiration
**Check Token Expiration:** Check if the token has expired.
```
// api/cache.go
func checkTokenExpiration(ctx *gin.Context, client *redis.Client) {
userID := ctx.Query("userID")
key := fmt.Sprintf("user:%s", userID)
ttl, err := client.TTL(ctx, key).Result()
if err != nil {
ctx.JSON(http.StatusInternalServerError, gin.H{
"error": "Failed to get TTL",
})
return
}
expired := ttl <= 0
ctx.JSON(http.StatusOK, expired)
}
```
## Conclusion
This setup provides a robust structure for managing JWT authentication with Redis in a Go application, ensuring efficient session management and token validation. If there are any questions feel free to ask(or ask GPT) my repo you can find bellow.

1,912,611 | Evaluating the Potential Returns of Investing in Cryptocurrency Wallet Development | Blockchain technology’s rapid development has led major financial organizations to invest heavily in... | 0 | 2024-07-05T10:25:47 | https://dev.to/kiararobbinson/evaluating-the-potential-returns-of-investing-in-cryptocurrency-wallet-development-3m6k | cryptocurrency, crypto, blockchain, technology | Blockchain technology’s rapid development has led major financial organizations to invest heavily in its benefits. Startups, enterprises, and even Fortune 500 companies are now deeply involved, and the demand for secure transactions has turned **[cryptocurrency wallet development](https://www.debutinfotech.com/crypto-wallet)** into a booming industry.
With a promising future for crypto trading and the ever-expanding fintech landscape, now is an ideal time to invest in developing a user-friendly crypto product. Through years of providing consultations and fintech software development services, Acropolium has harnessed the power of blockchain and SaaS technology.
Today, we will explain to you how to create a white label crypto wallet app with must-have features to elevate your operation. We will also explore some of our clients’ related success stories and try to estimate the **[crypto wallet development cost](https://www.debutinfotech.com/blog/how-much-does-it-cost-to-develop-a-crypto-wallet)**.
## What are Cryptocurrency Wallet Apps?
A crypto wallet app is software that allows you to manage and transfer cryptocurrency holdings. It is not a physical wallet; rather, it stores the keys to money kept on public blockchain networks.
By acting as virtual middlemen, these apps let users track their cryptocurrency balance and save both their public and private keys in one location. Ownership of stablecoins, NFTs, and other cryptocurrency assets is attributed to the wallet's address upon transfer.
Security is a primary concern in the creation of cryptocurrency wallets, financial SaaS solutions, and **[cryptocurrency exchange](https://www.debutinfotech.com/cryptocurrency-exchange-development)** software since cryptographic keys are essential for confirming user addresses and completing transactions.
## Types Of Crypto Wallets
The variety of options available for developing white label crypto wallets enables you to create a distinctive, scalable product that appeals to your target market. You can release different cryptocurrency wallets onto the market based on users' objectives.
Long-term investors, for example, who intend to hold their money for a long time, could favor wallets with strong security features. On the other hand, active traders could value speed and convenience more.
Crypto wallets are classified as cold, hot, or warm according to how connected they are to the internet.
## Hot Wallets
Hot wallets are software-based wallets that provide more user-friendliness but have slightly worse security than cold wallets.
To access a hot wallet, the user must first download a software program to their device. There are several kinds of hot wallets. They are described below:
- **Desktop wallets** are accessible from the original installation device and can be used on desktop or laptop computers. They provide security against computer virus attacks.
- **Mobile wallets** are similar to desktop equivalents in that they use NFC and QR code scanning to make payments at physical stores easier.
- **Web wallets**, which operate on the cloud and store private keys online for convenience, offer simple access to cryptocurrencies from any browser or mobile device. You can access the keys by establishing a connection with BaaS platforms. They are kept online. But be careful—cloud computing can also be vulnerable to hackers. To avoid this, work with a verified cryptocurrency development business.
## Cold Wallets
With these hardware wallets, you can save your keys offline on a gadget that isn't online. The form factors of several popular cold storage wallets are similar to USB devices. They occasionally arrive in the form of paper wallets printed with your private and public key information on a sheet of paper.
Cold storage is regarded by many cryptocurrency enthusiasts as the greatest choice for safeguarding digital assets. These wallets are thought to be difficult to attack because they are offline. Nevertheless, some are thinking of developing digital cryptocurrency wallets as they can easily misplaced or lost.
## Warm Wallets
Warm wallets combine the extra security of cold wallets with the transaction speed of hot wallets. Transactions can be generated automatically and keys are maintained online, but sending and signing transactions to the blockchain requires human interaction.
When it comes to qualities, different digital asset organizations have different objectives. For example, a cryptocurrency company that trades a lot could choose speed over all else, while an investor who wants to store assets for the long term might value security above all else when it comes to a cold wallet.
## The Rising Demand for Cryptocurrency Wallets
Cryptocurrency wallets are digital tools that allow users to store, manage, and transact their digital assets securely. As more individuals and enterprises recognize the benefits of blockchain technology, the need for reliable and user-friendly wallets has grown. Factors such as the decentralization of finance (DeFi), the emergence of non-fungible tokens (NFTs), and the increasing use of cryptocurrencies for everyday transactions have contributed to this demand surge.
Advanced coin management software is becoming more and more necessary as the worldwide cryptocurrency market expands. A Forbes Advisor study found that 42% of participants stated they invest in cryptocurrencies because it's simpler to get started with an app.
With a predicted 16.5% compound annual growth rate, the cryptocurrency market is expected to rise from $2.49 billion in 2024 to $4.59 billion in 2028. Digital accounting procedures and greater financial transaction transparency are predicted to fuel this expansion.

1,912,610 | Quantum Computers and AI: The Future is Now! | Alright, folks, let’s chat about two of the coolest tech trends that are about to shake things up:... | 0 | 2024-07-05T10:25:43 | https://dev.to/bytevillage/quantum-computers-and-ai-the-future-is-now-53p1 | ai, programming, python, computerscience |
Alright, folks, let’s chat about two of the coolest tech trends that are about to shake things up: quantum computers and artificial intelligence (AI). These powerhouses are like the Batman and Robin of the tech world, promising to crack the toughest problems and make our lives easier in ways we can't even imagine yet. So, buckle up, because we’re diving into how these bad boys are teaming up to create a revolution.
First off, what’s the deal with quantum computers? Imagine your regular computer as a super-fast librarian who can fetch books really quickly but one at a time. Now, picture a quantum computer as a super genius who can read and understand a million books at once. Quantum computers use something called qu-bits, which can be in multiple states simultaneously. This means they can handle insanely complex calculations at warp speed.
Why is this such a big deal? Well, quantum computers can solve problems that would take our current computers ages to crack. Need to figure out the best delivery routes for thousands of trucks? No problem. Want to simulate new drugs or materials? Easy peasy. They’re like having a superhero on your team.
Now, let’s talk about AI. We’re already living with AI every day—think Siri, Alexa, or those Netflix recommendations that know you better than your best friend. AI is all about machines learning from data, spotting patterns, and making decisions. And it’s getting smarter all the time.
Here’s where things get really exciting: when quantum computing and AI team up. Quantum computers can help AI learn faster and handle way more data. Imagine AI that can think on its feet even faster than before, spotting trends and making predictions with super accuracy. This combo could revolutionize everything from healthcare to finance.
For example, in healthcare, AI powered by quantum computing could analyze vast amounts of medical data to find new treatments and predict outbreaks before they happen. In finance, it could optimize investment strategies in ways we can’t even dream of yet. The possibilities are endless.
Sure, we’re not there yet. Quantum computers are still pretty new and can be a bit finicky. We need to iron out some kinks and make them more reliable. Plus, we need to figure out the best ways to integrate quantum computing with existing AI tech. But hey, Rome wasn’t built in a day.
As tech keeps advancing and we get better at harnessing these powerful tools, the future looks incredibly bright. Quantum computers and AI are set to transform industries in ways we’re just starting to understand. It’s like we’re standing on the brink of a new era, and the ride is going to be wild.
_So, stay tuned, folks. The revolution is just getting started, and it’s going to be one heck of an adventure._

1,912,504 | Virtual Columns in GBase 8s: Enhancing Data Operation Flexibility | In database management, we often need to dynamically generate new data columns based on existing... | 0 | 2024-07-05T09:35:43 | https://dev.to/congcong/virtual-columns-in-gbase-8s-enhancing-data-operation-flexibility-48m | database | In database management, we often need to dynamically generate new data columns based on existing data. The virtual column feature in GBase 8s provides an efficient way to meet this requirement. This article will detail the concept, definition, use cases, and related limitations of virtual columns in GBase 8s.
## 1. Definition of Virtual Columns
A virtual column is a data column defined using an expression or function. Logically, the virtual columns of a table have the same syntax as ordinary columns, but the values of virtual columns are not stored on any physical storage medium. Instead, they are calculated during the execution of SQL based on the expression or function defining the virtual column.
### Key Points:
1. Similar to ordinary columns, with no significant difference in use, except that values are calculated using expressions.
2. In the expression of a virtual column, you can include other columns of the same table, constants, SQL functions, and even some user-defined functions.
3. The value of a virtual column can only be seen when queried; unlike ordinary columns, it is not permanently stored on the disk. The value is calculated dynamically based on the expression.
For example:
```sql
create table t1 (id int, month_sal decimal(10,2,total_sal as(month_sal*12));
```
Here, `total_sal` is a virtual column that returns the value of `month_sal * 12`.
## 2. Syntax Explanation
- **column**: The name of the virtual column. The naming rules and constraints are consistent with the ordinary columns in the current version of GBase 8s. It cannot have the same name as other columns in the table and cannot be omitted.
- **datatype**: The data type of the virtual column. It supports the built-in data types of the current version of GBase 8s and can be omitted. If omitted, the data type of the virtual column matches the return type of the expression or function defining the virtual column (large objects, ROW, collections, and SERIAL types are not supported).
- **GENERATED ALWAYS**: Explicit declaration of the virtual column keyword, which can be omitted.
- **AS**: Explicit declaration of the virtual column keyword, which cannot be omitted.
- **column_expression**: The expression or constant used to define the virtual column. The expression can only reference columns in the current table and must have a unique return value. It cannot be omitted or reference other virtual columns.
For example:
```sql
-- Create table sc, where v_source is a virtual column.
CREATE TABLE sc (
stu_id INT PRIMARY KEY,
stu_nm VARCHAR2(50),
course_id INT,
source DECIMAL(10,2),
v_source VARCHAR(30) AS (
CASE
WHEN source < 60 THEN 'Fail'
WHEN source >= 60 THEN 'Pass'
END
) VIRTUAL
);
```
Insert data and then query, you can see that the value of the virtual column is dynamically generated based on the definition.
```sql
INSERT INTO sc (stu_id, stu_nm, course_id, source) VALUES (1, 'Zhang San', 9001, 56);
INSERT INTO sc (stu_id, stu_nm, course_id, source) VALUES (2, 'Li Sisi', 9001, 80);
SELECT * FROM sc;
```
Output:
```
stu_id | stu_nm | course_id | source | v_source
--------|-----------|-----------|--------|----------
1 | Zhang San | 9001 | 56.00 | Fail
2 | Li Sisi | 9001 | 80.00 | Pass
```
### Data Type Usage Restrictions
- Large objects, ROW, custom types, and collections are not supported.
- SERIAL, SERIAL8, and BIGSERIAL are not supported.
### Scope of Expressions
- Only columns in the current table can be referenced, and the expression must have a unique return value.
- Supports single column, constant expressions, conditional expressions, and function expressions.
- Supports user-defined functions and functions defined in PACKAGES.
- Cannot reference other virtual columns.
- Pseudo columns are not supported.
- Aggregate functions, LISTAGG(), and column-to-row functions are not supported.
## 3. Usage of Virtual Columns
### In DDL
- Can be defined in `CREATE TABLE`.
- Can be added via `ALTER TABLE ADD Col`.
- Can be modified via `ALTER TABLE MODIFY Col`.
### Modification Restrictions
- Data type and expression can be modified.
- Columns referenced by the expression cannot be modified.
- Cannot change a virtual column to an ordinary column or vice versa.
- Can be deleted via `ALTER TABLE DROP Col`.
- Cannot delete a column referenced by a virtual column directly; the virtual column must be deleted first.
- Supports comments via `COMMENT`.
- Does not support `DEFAULT` expressions.
- `CREATE AS SELECT` is not supported.
### Constraints and Indexes
| Constraint/Index | GBase 8s | ORACLE |
|---------------------|----------------------------------|---------|
| Primary Key | N | Y |
| Foreign Key | N | Y |
| NOT NULL/NULL | Y | Y |
| CHECK | Y | Y |
| UNIQUE/DISTINCT | N | Y |
| Index | Only supports function index. | Y |
### DML Usage
- `UPDATE` statements on virtual columns are not allowed.
- Can be used in the `WHERE` clause of `UPDATE/DELETE`.
- Supports `INSERT INTO t1 SELECT * FROM t2`.
### DQL Usage
- Cannot be used in `GROUP BY` clauses.
- Other query syntaxes are supported.
## 4. Querying Virtual Column Attributes
### System Tables
- **SYSCOLUMNS**
- `COLATTR` field: new values 256 or 768 indicate virtual columns. 768 if the data type is specified explicitly, 256 otherwise.
```sql
SELECT DISTINCT t.tabname, sysc.colname, sysc.colattr
FROM systables t, syscolumns sysc
WHERE sysc.tabid = t.tabid AND t.tabname = 'sc';
```
Output:
```
tabname | colname | colattr
--------|----------|--------
sc | course_id| 0
sc | source | 0
sc | stu_id | 128
sc | stu_nm | 0
sc | v_source | 768
```
- **SYSDEFAULTSEXPR**
- New `VTCOL` field: indicates whether the column is a virtual column (1) or a default expression (0).
```sql
SELECT t.tabname, d.colno, d.vtcol, d.default
FROM sysdefaultsexpr d, systables t
WHERE d.tabid = t.tabid AND t.tabname = 'sc' AND d.type = 'T';
```
Output:
```
tabname | colno | vtcol | default
--------|-------|-------|--------------------------------
sc | 5 | 1 | CASE WHEN (source < 60.00) THEN
sc | 5 | 1 | 'Fail' WHEN (source >= 60.00)
sc | 5 | 1 | THEN 'Pass' END
```
As an advanced feature of the GBase 8s database, virtual columns provide greater flexibility for data operations. Through this introduction, we have learned about the definition, creation, usage, and related restrictions of virtual columns. We hope this information helps you utilize the virtual column feature more effectively and enhance database management efficiency. | congcong |

Each table represents a different entity, and the relationships between these entities are maintained using keys. The relational model, introduced by E.F. Codd in 1970, uses SQL (Structured Query Language) for defining and manipulating the data.
**Key Concepts**
Tables (Relations): The fundamental structure in a relational database. Each table consists of rows and columns, where rows represent records and columns represent attributes of the entity.
Primary Keys: Unique identifiers for records within a table. A primary key ensures that each record can be uniquely identified.
Foreign Keys: Attributes that create a link between two tables. A foreign key in one table points to a primary key in another table, establishing a relationship between the two tables.
SQL: The standard language for querying and manipulating relational databases. SQL commands include SELECT, INSERT, UPDATE, DELETE, CREATE TABLE, and ALTER TABLE.
**Advantages of Relational Databases**
Data Integrity: The use of primary and foreign keys ensures that data remains consistent and accurate across the database. Constraints and rules can be applied to enforce data integrity.
Flexibility: SQL allows complex queries to be written easily, enabling users to retrieve and manipulate data in various ways.
Scalability: Relational databases can handle large amounts of data and can be scaled vertically by adding more resources to the existing hardware.
Security: Advanced security features such as role-based access control (RBAC) ensure that only authorized users can access or manipulate data.
ACID Properties: Transactions in relational databases adhere to ACID (Atomicity, Consistency, Isolation, Durability) properties, ensuring reliable processing of database transactions.
**Common Relational Database Systems**
MySQL: An open-source relational database management system widely used for web applications.
PostgreSQL: An advanced open-source database known for its robustness and support for advanced SQL features.
Oracle Database: A powerful commercial database known for its advanced features, scalability, and security.
Microsoft SQL Server: A relational database system developed by Microsoft, known for its integration with other Microsoft products and services.
**Applications of Relational Databases**
Enterprise Resource Planning (ERP): Relational databases are used to manage business processes across different departments such as accounting, HR, and supply chain.
Customer Relationship Management (CRM): These systems store and manage customer information, interactions, and sales data.
E-commerce: Online stores use relational databases to manage product inventories, customer orders, and transaction histories.
Healthcare: Relational databases are used to store patient records, medical histories, and treatment plans.
Finance: Banks and financial institutions use relational databases for transaction processing, customer account management, and financial reporting.
**Conclusion**
Relational databases play a crucial role in modern data management, offering robust features for data integrity, security, and flexible querying. They are essential for applications across various industries, from healthcare and finance to e-commerce and enterprise resource planning. | saumya27 |

Many people, when they start developing their multiplayer game think about the... | 0 | 2024-07-05T10:11:35 | https://dev.to/devsdaddy/ways-to-interact-with-the-network-in-unity-with-examples-for-organizing-multiplayer-games-464f | tutorial, networking, unity3d, multiplayer | Hey, everybody. Many people, when they start developing their multiplayer game think about the realization of the network part. In this article I would like to tell you about the main methods of network communication in the framework of client-server relations.
## Introduction
**Unity provides a powerful engine** for creating games and interactive applications, including **multiplayer networks**. The main task in creating a network game is to synchronize data between clients and server, which requires the use of network protocols. There are two main types of network protocols: **TCP and UDP, as well as their hybrid variants**. Let's look at each of them in the context of using them with Unity.
In addition to this, I suggest looking at various off-the-shelf networking solutions, including protocols for communicating between client and server, as well as writing your own socket-based protocol.
**So, Let's get started.**
---
## Basic network protocols
### TCP (Transmission Control Protocol)
**TCP** is a protocol that provides reliable data delivery. It ensures that data is delivered in the correct order and without loss. This is achieved through the use of acknowledgments and retransmissions.
**Advantages of TCP:**
- **Reliability:** guaranteed delivery of data.
- **Order:** data is delivered in the order in which it was sent.
- **Flow control:** controlling the rate at which data is transmitted.
**Disadvantages of TCP:**
- **Delays:** due to the need to confirm delivery.
- **Network load:** greater amount of service information.
### UDP (User Datagram Protocol)
**UDP** is a lighter weight protocol that does not provide reliable and orderly data delivery, but minimizes latency.
**Advantages of UDP:**
- **Less latency:** data is sent without waiting for an acknowledgement.
- **Less load:** less service information.
- **Suitable for real time:** better suited for games and applications that require fast updates (e.g. online shooters).
**UDP disadvantages:**
- **Unreliable:** packets can be lost or duplicated.
- **Lack of order:** packets can arrive in any order.
### WebSockets
**WebSockets** is a protocol designed for two-way communication between a client and a server over a single TCP connection. WebSockets are often used for web applications, but can also be useful for games, especially those that run in a browser.
**Benefits of WebSockets:**
- **Persistent connectivity:** maintains an open connection for two-way data exchange.
- **Ease of use:** integrates easily with web technologies.
**Disadvantages of WebSockets:**
- **TCP dependency:** shares all of its disadvantages.
- **May be redundant** for some types of games.
> For the most part, there are many add-ons and enhancements to the communication protocol for web-socket, for example json-rpc, which we will also cover in this article.
---
## Building client-server architecture in Unity
### Selecting a network library
As a basis for building multiplayer games, you can choose one of the many ready-made solutions for networking, or describe your own protocols for client and server.
**Unity supports several network libraries and services such as:**
- **UNet (deprecated):** the original Unity networking library, now considered deprecated.
- **Mirror:** a popular fork of UNet, actively supported and developed by the community.
- **Photon:** a cloud-based networking service that provides lightweight and powerful networking functionality.
- **Netcode for GameObjects:** a new library from Unity that supports modern approaches to network synchronization.
- **Heroic Nakama:** a large set of open source libraries for networking (also supports hosting in heroic labs cloud).
> Next, let's take a closer look at the advantages and disadvantages of off-the-shelf solutions with code examples for implementing simple networking.
---
## UNet
**UNet** is an obsolete built-in networking library in Unity that provided all the tools needed to create networked games. Although UNet is no longer supported and its use is not recommended for new projects, its legacy is still useful for learning the basic concepts of network gaming in Unity.
**Benefits of UNet:**
- **Integration with Unity:** UNet was built into Unity, making it easy to use and integrate with other engine components.
- **Documentation and examples:** At the time of its relevance, a lot of official and user materials were available, making it easy to learn and develop.
**Disadvantages of UNet:**
- **Obsolescence:** UNet is no longer supported by Unity, and new projects should not use it due to lack of updates and patches.
- **Limited functionality:** Compared to modern network libraries, UNet had limited features and performance.
- **Lack of support for cloud solutions:** UNet did not provide built-in support for cloud services for scalability and usability.
### Example of multiplayer game on UNet
Let's consider a simple example of creating a multiplayer game using UNet.
**Network Manager Setup:**
```csharp
using UnityEngine;
using UnityEngine.Networking;
public class NetworkManagerCustom : NetworkManager
{
public override void OnServerAddPlayer(NetworkConnection conn, short playerControllerId)
{
var player = Instantiate(playerPrefab);
NetworkServer.AddPlayerForConnection(conn, player, playerControllerId);
}
}
```
**Creating a network player:**
```csharp
using UnityEngine;
using UnityEngine.Networking;
public class PlayerController : NetworkBehaviour
{
void Update()
{
if (!isLocalPlayer)
return;
float move = Input.GetAxis("Vertical") * Time.deltaTime * 3.0f;
float turn = Input.GetAxis("Horizontal") * Time.deltaTime * 150.0f;
transform.Translate(0, 0, move);
transform.Rotate(0, turn, 0);
}
}
```
> As you can see, creating a simple solution on UNet is quite localized and fits into the Unity API, however UNet is not currently used in production projects due to its outdated status and limitations.
---
## Mirror
**Mirror** is an actively supported fork of UNet, providing updated and improved features. Mirror has become a popular choice for creating networked games due to its simplicity and powerful features.
**Benefits of Mirror:**
- **Active community:** Mirror has an active community of developers who regularly update and improve the library.
- **UNet compatibility:** Since Mirror is based on UNet, migrating from UNet to Mirror can be relatively easy.
- **WebGL support:** Mirror supports WebGL, allowing for the development of browser-based multiplayer games.
**Disadvantages of Mirror:**
- **Difficulty in customization:** Mirror can take more time to set up and understand compared to other solutions such as Photon.
- **Lack of built-in cloud support:** Like UNet, Mirror does not provide built-in cloud solutions, which can make it difficult to scale.
### Example of a multiplayer game on Mirror
Now, Let's consider a simple example of creating a multiplayer game using **Mirror**. As you can see - there are not many differences from **UNet**, from which **Mirror** emerged
**Network Manager Setup:**
```csharp
using UnityEngine;
using Mirror;
public class NetworkManagerCustom : NetworkManager
{
public override void OnServerAddPlayer(NetworkConnection conn)
{
var player = Instantiate(playerPrefab);
NetworkServer.AddPlayerForConnection(conn, player);
}
}
```
**Creating a network player:**
```csharp
using UnityEngine;
using Mirror;
public class PlayerController : NetworkBehaviour
{
void Update()
{
if (!isLocalPlayer)
return;
float move = Input.GetAxis("Vertical") * Time.deltaTime * 3.0f;
float turn = Input.GetAxis("Horizontal") * Time.deltaTime * 150.0f;
transform.Translate(0, 0, move);
transform.Rotate(0, turn, 0);
}
}
```
As you can already realize, **Mirror** is simply a development of the ideas of the original **UNet** with some improvements and fixes to the shortcomings of the original project. Despite the active love and large community, it is used with caution on large projects.

## Photon
**Photon** is a cloud-based networking service that provides easy and powerful tools for creating networked games. **Photon PUN** (Photon Unity Networking) is a popular library that allows developers to easily integrate networking functionality into their projects.
**Photon Advantages:**
- **Cloud infrastructure:** Photon offers a scalable cloud infrastructure that removes server side worries and simplifies server management.
- **Feature rich:** Photon provides many tools and features such as chat, rooms, matchmaking and data synchronization.
- **Multiple Platform Support:** Photon supports multiple platforms including mobile devices, PCs and consoles.
**Disadvantages of Photon:**
- **Cost:** Using Photon can be expensive, especially for games with a large number of users.
- **Dependency on a third-party service:** Using a third-party cloud service means dependency on its policies, updates, and availability.
### Example of multiplayer game on Photon
So, let's look at a small example for working with networking in Photon. For beginners, it is quite a simple solution combined with a lot of ready-made functionality.
**Setup Photon Manager:**
```csharp
using UnityEngine;
using Photon.Pun;
public class PhotonManager : MonoBehaviourPunCallbacks
{
void Start()
{
PhotonNetwork.ConnectUsingSettings();
}
public override void OnConnectedToMaster()
{
PhotonNetwork.JoinLobby();
}
public override void OnJoinedLobby()
{
PhotonNetwork.JoinRandomRoom();
}
public override void OnJoinRandomFailed(short returnCode, string message)
{
PhotonNetwork.CreateRoom(null, new Photon.Realtime.RoomOptions { MaxPlayers = 4 });
}
public override void OnJoinedRoom()
{
PhotonNetwork.Instantiate("PlayerPrefab", Vector3.zero, Quaternion.identity);
}
}
```
**Creating a network player:**
```csharp
using UnityEngine;
using Photon.Pun;
public class PlayerController : MonoBehaviourPunCallbacks, IPunObservable
{
void Update()
{
if (!photonView.IsMine)
return;
float move = Input.GetAxis("Vertical") * Time.deltaTime * 3.0f;
float turn = Input.GetAxis("Horizontal") * Time.deltaTime * 150.0f;
transform.Translate(0, 0, move);
transform.Rotate(0, turn, 0);
}
public void OnPhotonSerializeView(PhotonStream stream, PhotonMessageInfo info)
{
if (stream.IsWriting)
{
stream.SendNext(transform.position);
stream.SendNext(transform.rotation);
}
else
{
transform.position = (Vector3)stream.ReceiveNext();
transform.rotation = (Quaternion)stream.ReceiveNext();
}
}
}
```
As you can see, the implementation on Photon seems a bit larger than on UNet, but you need to realize that it has more functionality out of the box, allowing you to think less about networking issues.

## Netcode for GameObjects
**Netcode for GameObjects** is a new library from Unity designed for creating modern networked games with support for all modern approaches to synchronization and management of networked objects.
**Benefits of Netcode for GameObjects:**
- **Modern approaches:** Netcode for GameObjects offers modern methods for synchronizing and managing networked objects.
Integration with Unity: As an official Unity solution, Netcode for GameObjects integrates with the latest versions of Unity and its ecosystem.
- **PlayFab support:** Netcode for GameObjects integrates with PlayFab, making it easy to create and manage scalable multiplayer games.
**Disadvantages of Netcode for GameObjects:**
- **New technology:** Being a relatively new library, Netcode for GameObjects may have fewer examples and tutorials compared to more mature solutions.
- **Incomplete documentation:** Documentation and examples may be less extensive compared to Photon or Mirror, which can complicate training and development.
- **Difficulty of transition:** For developers using other network libraries, transitioning to Netcode for GameObjects may require significant effort.
### Example of multiplayer game on Netcode for GameObjects
Now let's look at an equally small example of networking using Netcode for GameObjects
**Creating of Net Manager:**
```csharp
using Unity.Netcode;
using UnityEngine;
public class NetworkManagerCustom : MonoBehaviour
{
void Start()
{
NetworkManager.Singleton.StartHost();
}
}
```
**Creating a network player:**
```csharp
using Unity.Netcode;
using UnityEngine;
public class PlayerController : NetworkBehaviour
{
void Update()
{
if (!IsOwner)
return;
float move = Input.GetAxis("Vertical") * Time.deltaTime * 3.0f;
float turn = Input.GetAxis("Horizontal") * Time.deltaTime * 150.0f;
transform.Translate(0, 0, move);
transform.Rotate(0, turn, 0);
}
}
```
Creating multiplayer games in Unity has become more accessible thanks to various network libraries and services such as **UNet**, **Mirror**, **Photon** and **Netcode for GameObjects**. Each of these libraries has its own features and advantages, allowing developers to choose the most suitable solution for their projects.
> However, this is not the only option and for a deeper understanding of the work, let's look at the option of writing your own network engine and using modern protocols for this.
---
## Build your own UDP-based communication
Next we will try to create a simple client and server for your games based on the UDP protocol. We have talked about its advantages and disadvantages above.
**Building UDP Server:**
```csharp
using System.Net;
using System.Net.Sockets;
using System.Text;
using System.Threading;
public class UdpServer
{
private UdpClient udpServer;
private IPEndPoint clientEndPoint;
public UdpServer(int port)
{
udpServer = new UdpClient(port);
clientEndPoint = new IPEndPoint(IPAddress.Any, 0);
}
public void Start()
{
Thread receiveThread = new Thread(new ThreadStart(ReceiveData));
receiveThread.Start();
}
private void ReceiveData()
{
while (true)
{
byte[] data = udpServer.Receive(ref clientEndPoint);
string message = Encoding.UTF8.GetString(data);
Debug.Log("Received: " + message);
// Say hello from server to client
SendData("Hello from server");
}
}
private void SendData(string message)
{
byte[] data = Encoding.UTF8.GetBytes(message);
udpServer.Send(data, data.Length, clientEndPoint);
}
}
```
**Now, let's build an UDP client:**
```csharp
using System.Net;
using System.Net.Sockets;
using System.Text;
public class UdpClient
{
private UdpClient udpClient;
private IPEndPoint serverEndPoint;
public UdpClient(string serverIp, int serverPort)
{
udpClient = new UdpClient();
serverEndPoint = new IPEndPoint(IPAddress.Parse(serverIp), serverPort);
}
public void SendData(string message)
{
byte[] data = Encoding.UTF8.GetBytes(message);
udpClient.Send(data, data.Length, serverEndPoint);
}
public void ReceiveData()
{
udpClient.BeginReceive(new AsyncCallback(ReceiveCallback), null);
}
private void ReceiveCallback(IAsyncResult ar)
{
byte[] data = udpClient.EndReceive(ar, ref serverEndPoint);
string message = Encoding.UTF8.GetString(data);
Debug.Log("Received: " + message);
// Recieve Processing
ReceiveData();
}
}
```
> Thus we have simply exchanged messages via UDP, but you should realize that in order to build your own network - you will have to lay a lot of functionality, watch for packet loss and use UDP better in cases where we do not care about data loss (for example, for some analytical purposes).
---
## Implementation by the example of WebSockets
One of the most popular ways to build a network is based on **Web Sockets**. Many solutions choose it as a reliable and time-tested TCP-based protocol. In addition, additional solutions to improve communication can be bolted on to it (which we will discuss further), but for now let's look at the basic implementation.
**Creating a WebSocket server (using WebSocketSharp):**
```csharp
using WebSocketSharp.Server;
using WebSocketSharp;
public class WebSocketServer
{
private WebSocketServer wss;
public WebSocketServer(int port)
{
wss = new WebSocketServer(port);
wss.AddWebSocketService<ChatBehavior>("/Chat");
}
public void Start()
{
wss.Start();
}
public void Stop()
{
wss.Stop();
}
}
public class ChatBehavior : WebSocketBehavior
{
protected override void OnMessage(MessageEventArgs e)
{
Send("Hello from server");
}
}
```
**Create a basic WebSocket Client (using WebSocketSharp):**
```csharp
using WebSocketSharp;
public class WebSocketClient
{
private WebSocket ws;
public WebSocketClient(string serverUrl)
{
ws = new WebSocket(serverUrl);
ws.OnMessage += (sender, e) =>
{
Debug.Log("Received: " + e.Data);
};
}
public void Connect()
{
ws.Connect();
}
public void SendData(string message)
{
ws.Send(message);
}
public void Close()
{
ws.Close();
}
}
```
In terms of comparing basic approaches, building a client-server network in Unity requires understanding the different network protocols and choosing the right library or service. **TCP is suitable** for applications that require reliability and data consistency, while **UDP is better suited for games** with high speed requirements and low latency. **WebSockets offer flexibility** for web applications and ease of use.
Depending on the requirements of your project, you can choose the most appropriate protocol and tools to create an efficient and reliable client-server network.
**Now let's take a look at the various add-ons over WebSocket and over protocols to simplify the work of exchanging data between client and server.**
---
## Messaging protocols
**Messaging protocols** serve as a simplification for server and client communication, by which you can send various events to the server and it will in due course do a calculation and give you the result using the same protocol. They are usually built on top of off-the-shelf network protocols like WebSocket, etc.
**Today we'll look at several variations of messaging protocols:**
- **JSON-RPC:** is a simple remote procedure call (RPC) protocol that uses JSON;
- **REST:** is an architectural style that uses standard HTTP methods and can also be used on sockets;
- **gRPC:** high-performance HTTP/2-based remote procedure call protocol;
**And of course, let's try to create our own fast protocol for exchanging messages between client and server.**
---
## JSON RPC
### What is JSON-RPC?
**JSON-RPC** is a simple remote procedure call (RPC) protocol that uses JSON (JavaScript Object Notation) to encode messages. JSON-RPC is lightweight and uncomplicated to implement, making it suitable for a variety of applications, including games.
**Advantages of JSON-RPC:**
- **Simplicity:** JSON-RPC is easy to use and implement.
- **Lightweight:** Using JSON makes messages compact and easy to read.
- **Wide compatibility:** JSON-RPC can be used with any programming language that supports JSON.
**Disadvantages of JSON-RPC:**
- **Limited functionality:** JSON-RPC does not provide features such as connection management or real-time data stream processing.
- **Does not support two-way communication:** JSON-RPC works on a request-response model, which is not always convenient for games that require constant state updates.
### Example of using JSON-RPC in Unity
**Python server using Flask and Flask-JSON-RPC:**
```python
from flask import Flask
from flask_jsonrpc import JSONRPC
app = Flask(__name__)
jsonrpc = JSONRPC(app, '/api')
@jsonrpc.method('App.echo')
def echo(s: str) -> str:
return s
if __name__ == '__main__':
app.run(host='0.0.0.0', port=5000)
```
**Client in Unity using UnityWebRequest:**
```csharp
using UnityEngine;
using UnityEngine.Networking;
using System.Text;
public class JSONRPCClient : MonoBehaviour
{
private const string url = "http://localhost:5000/api";
void Start()
{
StartCoroutine(SendRequest("Hello, JSON-RPC!"));
}
IEnumerator SendRequest(string message)
{
string jsonRequest = "{\"jsonrpc\":\"2.0\",\"method\":\"App.echo\",\"params\":[\"" + message + "\"],\"id\":1}";
byte[] body = Encoding.UTF8.GetBytes(jsonRequest);
using (UnityWebRequest request = new UnityWebRequest(url, "POST"))
{
request.uploadHandler = new UploadHandlerRaw(body);
request.downloadHandler = new DownloadHandlerBuffer();
request.SetRequestHeader("Content-Type", "application/json");
yield return request.SendWebRequest();
if (request.result != UnityWebRequest.Result.Success)
{
Debug.LogError(request.error);
}
else
{
Debug.Log(request.downloadHandler.text);
}
}
}
}
```
> Often JSON-RPC can be an option for exchanging data with an authorization server, or matchmaking, which gives room launch data for your games. It is easy to install, customize, and understand when developing your games.
---
## REST
### What is REST?
**REST (Representational State Transfer)** is an architectural style that uses standard HTTP methods (GET, POST, PUT, DELETE) to communicate between a client and a server. RESTful API is widely used in web applications and can be useful for creating game servers.
**Advantages of REST:**
- **Broad support:** REST uses standard HTTP, making it compatible with most platforms and programming languages.
- **Simplicity:** Easy to implement and understand by using standard HTTP methods.
- **Caching:** HTTP allows responses to be cached, which can improve performance.
**Disadvantages of REST:**
- **Not optimal for real-time:** REST uses a request-response model, which is not always suitable for applications that require constant updates.
- **Data overload:** Each HTTP message can contain redundant headers that increase the amount of data transferred.
> Most often, REST, like JSON-RPC is used for basic exchange with your server's API. It is convenient to get profile data and other data models for meta-game.
### REST Examples
**NodeJS simple server with Express Framework:**
```javascript
const express = require('express');
const app = express();
const port = 3000;
app.use(express.json());
app.post('/echo', (req, res) => {
res.json({ message: req.body.message });
});
app.listen(port, () => {
console.log(`Server listening at http://localhost:${port}`);
});
```
**Unity client with UnityWebRequest:**
```csharp
using UnityEngine;
using UnityEngine.Networking;
using System.Text;
public class RESTClient : MonoBehaviour
{
private const string url = "http://localhost:3000/echo";
void Start()
{
StartCoroutine(SendRequest("Hello, REST!"));
}
IEnumerator SendRequest(string message)
{
string jsonRequest = "{\"message\":\"" + message + "\"}";
byte[] body = Encoding.UTF8.GetBytes(jsonRequest);
using (UnityWebRequest request = new UnityWebRequest(url, "POST"))
{
request.uploadHandler = new UploadHandlerRaw(body);
request.downloadHandler = new DownloadHandlerBuffer();
request.SetRequestHeader("Content-Type", "application/json");
yield return request.SendWebRequest();
if (request.result != UnityWebRequest.Result.Success)
{
Debug.LogError(request.error);
}
else
{
Debug.Log(request.downloadHandler.text);
}
}
}
}
```
---
## gRPC
### What is gRPC?
**gRPC** is a **high-performance remote procedure call protocol** developed by Google. gRPC uses **HTTP/2** for data transport and Protocol Buffers (protobuf) for message serialization, which provides high performance and low latency.
**Benefits of gRPC:**
- **High performance:** The use of HTTP/2 and protobuf ensures fast and efficient data transfer.
- **Multi-language support:** gRPC supports multiple programming languages.
- **Streaming:** Supports real-time data streaming.
**Disadvantages of gRPC:**
- **Complexity:** More difficult to configure and use compared to REST.
- **Need to learn protobuf:** Requires knowledge of Protocol Buffers for message serialization.
### Examples of gRPC usage for Unity Games
**Python server using grpcio:**
```python
import grpc
from concurrent import futures
import time
import echo_pb2
import echo_pb2_grpc
class EchoService(echo_pb2_grpc.EchoServiceServicer):
def Echo(self, request, context):
return echo_pb2.EchoReply(message='Echo: ' + request.message)
def serve():
server = grpc.server(futures.ThreadPoolExecutor(max_workers=10))
echo_pb2_grpc.add_EchoServiceServicer_to_server(EchoService(), server)
server.add_insecure_port('[::]:50051')
server.start()
try:
while True:
time.sleep(86400)
except KeyboardInterrupt:
server.stop(0)
if __name__ == '__main__':
serve()
```
**Client in Unity using gRPC C#:**
```csharp
using UnityEngine;
using Grpc.Core;
using GrpcEcho;
public class GRPCClient : MonoBehaviour
{
private Channel channel;
private EchoService.EchoServiceClient client;
void Start()
{
channel = new Channel("localhost:50051", ChannelCredentials.Insecure);
client = new EchoService.EchoServiceClient(channel);
var reply = client.Echo(new EchoRequest { Message = "Hello, gRPC!" });
Debug.Log("Received: " + reply.Message);
}
void OnDestroy()
{
channel.ShutdownAsync().Wait();
}
}
```
> The choice of messaging protocol for creating networked games in Unity depends on the specific requirements of the project. JSON-RPC and REST are easy to use and implement, but may not be suitable for applications that require real-time data exchange. gRPCs provide low latency and efficient data transfer, but require more complex configuration and connection management. Understanding the features of each protocol will help developers choose the best solution for their game projects.

## Creating your own WebSocket-based binary messaging protocol
**WebSocket** is an excellent protocol for creating games that require real-time communication. It supports two-way communication between client and server over a single **TCP connection**, which provides low latency and efficiency. Next, we'll look at how to create your own **WebSocket-based binary messaging protocol** for games on Unity.
### Why a binary protocol?
**Binary protocols offer several advantages over text-based protocols (e.g. JSON or XML):**
- **Efficiency:** Binary data takes up less space than text-based formats, which reduces the amount of information transferred and speeds up transmission.
- **Performance:** Parsing binary data is typically faster than parsing text formats.
- **Flexibility:** Binary protocols allow for more efficient encoding of different data types (e.g., floating point numbers, integers, fixed-length strings, etc.).
### Binary protocol basics
When creating a binary protocol, it is important to define the **format of messages**. Each message should have a **well-defined structure** so that both client and server can interpret the data correctly.
**A typical message structure might include:**
- **Header:** Information about the message type, data length, and other metadata.
- **Body:** The actual message data.
**Example message structure:**
- **Message Type (1 byte):** Specifies the message type (e.g. 0x01 for player movement, 0x02 for attack, etc.).
- **Data length (2 bytes):** The length of the message body.
- **Message Body (variable length):** Contains data specific to each message type.
### Binary protocol implementation in Unity
First, let's create a **WebSocket server on Node.js** that will receive and process binary messages.
**Server Code:**
```javascript
const WebSocket = require('ws');
const wss = new WebSocket.Server({ port: 8080 });
wss.on('connection', ws => {
ws.on('message', message => {
// Parse Message Type
const messageType = message.readUInt8(0);
switch (messageType) {
case 0x01:
// Handle Player Movement
handlePlayerMove(message);
break;
case 0x02:
// Handle Attack Message
handlePlayerAttack(message);
break;
default:
console.log('Unknown Message Type:', messageType);
}
});
});
function handlePlayerMove(message) {
const playerId = message.readUInt16BE(1);
const posX = message.readFloatBE(3);
const posY = message.readFloatBE(7);
console.log(`The Player ${playerId} moved to (${posX}, ${posY})`);
}
function handlePlayerAttack(message) {
const playerId = message.readUInt16BE(1);
const targetId = message.readUInt16BE(3);
console.log(`Player ${playerId} attacked ${targetId}`);
}
console.log('Server based on WebSocket runned at port 8080');
```
**And don't forget about depedencies:**
```javascript
npm install ws
```
**Now let's create a client in Unity that will send binary messages to the server (Based on WebSocketSharp library):**
```csharp
using UnityEngine;
using WebSocketSharp;
using System;
public class WebSocketClient : MonoBehaviour
{
private WebSocket ws;
void Start()
{
ws = new WebSocket("ws://localhost:8080");
ws.OnMessage += (sender, e) =>
{
Debug.Log("Message Received: " + BitConverter.ToString(e.RawData));
};
ws.Connect();
// Send Movement Data
SendPlayerMove(1, 10.0f, 20.0f);
// Send Attack Data
SendPlayerAttack(1, 2);
}
void OnDestroy()
{
ws.Close();
}
private void SendPlayerMove(int playerId, float posX, float posY)
{
byte[] message = new byte[11];
message[0] = 0x01; // Message Type
BitConverter.GetBytes((ushort)playerId).CopyTo(message, 1);
BitConverter.GetBytes(posX).CopyTo(message, 3);
BitConverter.GetBytes(posY).CopyTo(message, 7);
ws.Send(message);
}
private void SendPlayerAttack(int playerId, int targetId)
{
byte[] message = new byte[5];
message[0] = 0x02; // Message Type
BitConverter.GetBytes((ushort)playerId).CopyTo(message, 1);
BitConverter.GetBytes((ushort)targetId).CopyTo(message, 3);
ws.Send(message);
}
}
```

> Here we covered the basics of binary protocols, their advantages and disadvantages, and gave an example of implementing a server in Node.js and a client in Unity. Using binary messages can significantly reduce overhead and increase the performance of a network game.
## Conclusion
Networking is a complex process that encompasses many nuances to implement. In general, we have covered basic protocols for transport and messaging, and next time we will learn more advanced examples of synchronizing players, data and try to create our own matchmaking.
**And of course thank you for reading the article, I would be happy to discuss your own networking schemas.**

1,912,506 | Automating User and Group Management on Linux with a Bash Script | Hey there! I’m excited to share the details of my Stage 1 task for the HNG DevOps Internship. This... | 0 | 2024-07-05T09:39:44 | https://dev.to/hellowale/automating-user-and-group-management-on-linux-with-a-bash-script-46gl | bash, devops, productivity | Hey there!
I’m excited to share the details of my Stage 1 task for the HNG DevOps Internship. This task involved creating a Bash script to automate the process of user and group management on a Linux system
## Task:
Your company has employed many new developers. As a SysOps engineer, write a bash script called create_users.sh that reads a text file containing the employee’s usernames and group names, where each line is formatted as user; groups.
The script should create users and groups as specified, set up home directories with appropriate permissions and ownership, generate random passwords for the users, and log all actions to /var/log/user_management.log. Additionally, store the generated passwords securely in /var/secure/user_passwords.txt.
Ensure error handling for scenarios like existing users and provide clear documentation and comments within the script.
## Sample Input
```
light; sudo,dev,www-data
idimma; sudo
mayowa; dev,www-data
```
## Solution
The script solves the problem by following these procedures:
Step 1: Reading the Input File
First, we read the input file using a function that adds the users to a global variable called users and the groups to another variable called group_list. It does this simultaneously, allowing the index of each user in users to match their corresponding groups in group_list. We also ensure the user has entered a valid input file before running this.
Here's the code that does all of this:
```
declare -a users
declare -a group_list
# Function to read and parse the input file
read_input_file() {
local filename="$1"
while IFS=';' read -r user groups; do
users+=("$(echo "$user" | xargs)")
group_list+=("$(echo "$groups" | tr -d '[:space:]')")
done < "$filename"
}
# Check for input file argument
if [[ $# -ne 1 ]]; then
echo "Usage: $0 <input_file>"
exit 1
fi
input_file="$1"
echo "Reading input file: $input_file"
read_input_file "$input_file"
```
Step 2: Creating Required Files and Directories
Next, we create the required files and their directories if they don't already exist using this code:
```
log_file="/var/log/user_management.log"
password_file="/var/secure/user_passwords.txt"
# Create log and password files if they do not exist
mkdir -p /var/log /var/secure
touch "$log_file"
touch "$password_file"
chmod 600 "$password_file"
```
Step 3: Creating Users and Groups
At this point, we have a list of the users in users, a list of their corresponding groups in group_list, and all the files we need to store valuable information such as logs and the passwords of the users we created.
Now, we use a for loop to iterate over each user and their corresponding groups with an index. Since we created the users and group_list arrays simultaneously by looping over each line in the file, the user at index 0 in users needs to be added to the groups at index 0 in group_list. So our for loop will look like this:
```
# Process each user
for ((i = 0; i < ${#users[@]}; i++)); do
username="${users[i]}"
user_groups="${group_list[i]}"
if [[ "$username" == "" ]]; then
continue # Skip empty usernames
fi
create_user_with_group "$username"
set_user_password "$username"
add_user_to_groups "$username" "$user_groups"
done
echo "User creation and group assignment completed." | tee -a "$log_file"
```
So username is the user we are working on and user_groups are the groups we are adding them to.
Next, we check if the user exists. If they do, we just continue with the next iteration; else, we create them with this code:
```
# Function to create a user with its personal group
create_user_with_group() {
local username="$1"
if id "$username" &>/dev/null; then
echo "User $username already exists." | tee -a "$log_file"
else
groupadd "$username"
useradd -m -g "$username" -s /bin/bash "$username"
echo "Created user $username with personal group $username." | tee -a "$log_file"
fi
}
```
Step 4: Setting User Password
We set a password for the user by using openssl to generate 12 random base64 characters. We then store the user's password in /var/secure/user_passwords.txt.
These are done using the code below:
```
# Function to set a password for the user
set_user_password() {
local username="$1"
local password=$(openssl rand -base64 12)
echo "$username:$password" | chpasswd
echo "$username,$password" >> "$password_file"
echo "Password for $username set and stored." | tee -a "$log_file"
}
```
Step 5: Adding Users to Groups
Next, we add the user to their groups. We do this by first checking if the group exists. If it doesn't, we create the group and then add the user to the group.
See the code below:
```
# Function to add user to additional groups
add_user_to_groups() {
local username="$1"
IFS=',' read -r -a groups <<< "$2"
for group in "${groups[@]}"; do
if ! getent group "$group" &>/dev/null; then
groupadd "$group"
echo "Group $group created." | tee -a "$log_file"
fi
usermod -aG "$group" "$username"
echo "Added $username to group $group." | tee -a "$log_file"
done
}
```
## Summary
And just like that, all new employees now have user profiles! You can also reuse this script for new employees. Exciting, right?
You will also notice how I appropriately log each event in the log file and gracefully handle failures in each command. So even if we run into unexpected problems in our execution, we not only end the program gracefully, but we also have a log for further investigation.
## Benefits of Automation
- Efficiency: Automates repetitive tasks, freeing up time for more critical activities.
- Consistency: Ensures that user and group configurations are applied uniformly.
- Security: Randomly generated passwords enhance security, and storing them securely minimizes risks.
