Q: RxJava2 Observable backpressure recently I realized that I don't understand how RxJava2 backpressure works.
I made small test and I expect that it should fail with MissingBackpressureException exception:
@Test
public void testBackpressureWillFail() {
Observable.<Integer>create(e -> {
for (int i = 0; i < 10000; i++) {
System.out.println("Emit: " + i);
e.onNext(i);
}
e.onComplete();
})
.subscribeOn(Schedulers.newThread())
.observeOn(Schedulers.computation())
.doOnNext(i -> {
Thread.sleep(100);
System.out.println("Processed:" + i);
})
.blockingSubscribe();
}
System out shows next:
Emit: 0
Emit: 1
Emit: 2
...
Emit: 10000
Processed:0
Processed:1
Processed:2
...
Processed:10000
Why it doesn't produce MissingBackpressureException.
I expect that e.onNext(i); will put item into buffer of ObservableObserveOn and after it's size is greater than static final int BUFFER_SIZE = Math.max(16,Integer.getInteger("rx2.buffer-size",128).intValue());
It should throw MissingBackpressureException which doesn't happen. Does the buffer automatically grow? If not where are items stored?
A: That's because backpressure moved out to Flowableonly with RxJava2, see here.
If you will switch to Flowable with BackpressureStrategy.MISSING you will get the exception.
That also means that in your case you indeed have buffer that automatically grows,
from observerOn docs:
Modifies an ObservableSource to perform its emissions and notifications on a specified Scheduler, asynchronously with an unbounded buffer...

Q: Ansible idempotency issue with unarchive and then modify extracted file In one of the ansible roles we extract some tar.gz file and then we replace one of the extracted files with another one to fix some issue.
The problem is when we run ansible again, ansible is extracting the archive back again since the directory content is changed and naturally marking the task changed and also replaces the file again as expected.
So we have two "changes" now everytime we run the playbook...
How should I handle this issue to keep the operation idempotent?
A: Use exclude option to ignore certain paths, see documentation.
i.e.
- unarchive:
src: https://example.com/example.zip
dest: /usr/local/bin
remote_src: True
exclude: bad.config
creates might also suit you, unarchive step will not be run if specified path already exists on remote machine

Q: how to use directive @push in blade template laravel I need script only on one page. and it should load after jQuery.
I tried in index.blade
<script type="text/javascript" src="{{ URL::asset ('js/jquery.js') }}"></script>
@push('custom-scripts')
<script type="text/javascript" src="{{ URL::asset ('js/custom-scripts.js') }}"></script>
@endpush
and then I should use @stack('custom-scripts') in my view?
A: You just need to make that the opposite way, @push is meant to be in the child view, which is pushing content to the parent @stack directive.
So your index.blade.php should have a:
@stack('custom-scripts')
And your child view:
@push('custom-scripts')
<script type="text/javascript" src="{{ URL::asset ('js/custom-scripts.js') }}"></script>
@endpush
You can also use @parent directive with @section like this:
//index.blade.php
@yield('scripts')
//child.blade.php
@section('scripts')
@parent
<!-- The rest of your scripts -->
@endsection
If you need more info I'd recommend you to check the documentation. Hope this helped you.

A: Using @once might be also helpful for someone to prevent scripts from being executed more than once. You can define your root view to have a fixed place for scripts that should go at the end of the <head> tag and at the end of the <body> tag:
app.blade.php:
<html>
<head>
<title>Website</title>
@stack('head-scripts')
</head>
<body>
<main>@yield('content')</main>
@stack('body-scripts')
</body>
</html>
home.blade.php:
@extends('layouts.app')
@section('content')
<div>Hello World</div>
@push('body-scripts')
@once
<script src="https://unpkg.com/imask"></script>
@endonce
@endpush

Q: Java Money - Smallest Unit of currency I have a downstream service (Stripe) which requires I send currency in the smallest currency unit (zero-decimal currency in their docs). I.e. to charge $1 I would send { "currency": "USD", amount: 100 } and to charge ¥100 I would send { "currency": "YEN", amount: 100 }
My upstream applications do not want to handle the currency in this way and want to use standard currency formats. Is there a means of transforming javax.money.MonetaryAmount into a zero decimal currency format?
Or am I going to have to write the conversions manually?
A: I've seen some people use BigDecimal.
Here it is as a function. Please write some tests for it :) :
public static BigDecimal currencyNoDecimalToDecimal(int amount, String currencyCode) {
Currency currency = Currency.getInstance(currencyCode); // ISO 4217 codes
BigDecimal bigD = BigDecimal.valueOf(amount);
System.out.println("bigD = " + bigD); // bigD = 100
BigDecimal smallD = bigD.movePointLeft(currency.getDefaultFractionDigits());
System.out.println("smallD = " + smallD); // smallD = 1.00
return smallD;
}
public static void main(String[] args) {
int amount = 100;
String currencyCode = "USD";
BigDecimal dollars = currencyNoDecimalToDecimal(amount, currencyCode);
System.out.println("dollars = "+dollars);
}

Q: (React-Native) undefined is not a constructor evaluating 'new FormData()' for the past 2 days I struggled with this problem and can't figure it out.
I don't understand this error. this is my code:
try{
var formData = new FormData();
} catch (error) {
console.error('FormData ERROR', error);
}
and this is the error:
017-06-21 13:49:02.761 [error][tid:com.facebook.React.JavaScript]
'FormData ERROR', { [TypeError: undefined is not a constructor
(evaluating 'new FormData()')] line: 98419, column: 36, sourceURL:
'http://localhost:8081/index.ios.bundle?platform=ios&dev=true&minify=false'
}
Do i have to add support for FormData in ReactNative 0.45.0?
please help
A: I got into this problem as well and that's because I have imported them on top.
If you have done like what I did:
import { FormData } from 'react';
or
import { FormData } from 'react-native';
Just remove "FormData" from your imports and it will work like magic. FormData doesn't have to be imported for it to be working.

Just remove "FormData" from your imports and it will work like magic. FormData doesn't have to be imported for it to be working.
A: The error says that you are FormData is undefined. Since it is not part of react native, you probably have to download it from npm.
npm install --save form-data
Then import it at the top of your file
import FormData from 'form-data';
A: if
import { FormData } from 'react-native';
didn't help then you can try to import directly:
import FormData from 'react-native/Libraries/Network/FormData';
A: I think I got it.
First of all, I found something (don't know from where i had these "tips") in my index.ios.js and removed them
// const _XHR = GLOBAL.originalXMLHttpRequest ?
// GLOBAL.originalXMLHttpRequest :
// GLOBAL.XMLHttpRequest
// XMLHttpRequest = _XHR;
// // FormData = global.originalFormData;
Then I found out that my debugger (Chrome or RNDebugger) messed with my network requests and that was bad for multipart image object. (strange?!)
finally i got it working with this code:
var fdObject = new FormData();
fdObject.append('avatar', {uri: PicturePath, name: 'avatar.jpg', type: 'image/jpg'});
options.method = POST;
options.headers['Content-Type'] = 'multipart/form-data';
options.body = fdObject;
fetch("http://api.com/post-my-image", options);

Q: VirtualBox supR3HardenedMainInitRuntime! error I get this error every time i try to launch VBox, after some researches i found that it maybe because installing vbox.deb placed in other folder not in /opt. (i tried many other solution like reinstalling ...).
could any one propose other solution to me and/or explain to me how do i make my deb install in /opt folder thank you.

A: At first,try
sudo apt-get update
sudo apt-get install --reinstall virtualbox
It may not be helpful,then this may give a hand:
enter link description here
And in the end,you can try to reboot the machine.Is it is not work,then i have no idea.i hope one of them is able to solve you problem.
A: https://www.virtualbox.org/ticket/16759
in my machine
celticmachine:/var/log# ls -ld /usr

celticmachine:/var/log# chown root:root /usr
celticmachine:/var/log# chown root:root /usr/lib
celticmachine:/var/log# virtualbox
And virtualbox started....
(Debian stretch)
A: Had the same issue after upgrading to Ubuntu 18.04. apt install --reinstall virtualbox didn't help, here's what worked for me:
apt purge virtualbox
apt autoclean
apt autoremove
apt install virtualbox
A: This error is not a virtualbox bug, look at this: Ticket #16759
It comes when you install something to /usr manually, and change the permission or ownership of /usr, /usr/lib.
So the solution is just to recover them as they used to be:
sudo chown root:root /usr
sudo chown root:root /usr/lib
sudo chown root:root /usr/lib/virtualbox
sudo chmod 755 /usr/lib
The reference of this answer is here: cannot run virtualbox on ubuntu 16.04
A: My virtualbox failure occurred with the last update made on 16/Mar/2022
usuario-vbox@dell-r730:~$ VBoxHeadless --startvm mysql-vm &
[1] 768281
usuario-vbox@dell-r730:~$ VBoxHeadless: Error -1912 in supR3HardenedMainInitRuntime!
VBoxHeadless: RTR3InitEx failed with rc=-1912
VBoxHeadless: Tip! It may help to reinstall VirtualBox.
^C
[1]+ Exit 1 VBoxHeadless --startvm mysql-vm
...
...
They were not turned off from the virtualbox manager. Only from the inside with
shutdown -h now
I followed the directions above
apt remove virtualbox --purge
apt autoclean
apt autoremove
reboot ...the server so that the latest updated kernel is loaded on March 16 along with the other libraries.
apt install virtualbox
I started the VMs with the commands manually
VBoxHeadless --startvm name1-vm &
VBoxHeadless --startvm name2-vm &
VBoxHeadless --startvm name3-vm &
VBoxHeadless --startvm name4-vm &
VBoxHeadless --startvm name5-vm &
Everything ok was working

Q: router.navigate doesn't work I have tried to redirect the page after getting data successfully deleted. So I put the redirect router.navigate inside of the subscribe of the data section. But it's not working and also I have tried with ngZone also nothing happens. And I want to show the success message also. How can I show that?
without ngZone:
const rid = params['rid'];
this.roleSer.deleteRole(rid).subscribe(
data => { this.router.navigate(['viewroles']) },
error => { error }
);
});

const vrid = this.route.params.subscribe((params: Params) => {
const rid = params['rid'];
this.roleSer.deleteRole(rid).subscribe(
data => { this.zone.run(()=>{
this.router.navigate(['viewroles'])

Q: Declare Field as Parameterized List Using java assist We can declare field like following code.
evalClass.addField(CtField.make("private java.util.List abc;", evalClass));
How can we declare field List<String> abc using java assist?
A: Done little bit research on CtField class. we can set through setGenericSignature.
CtField f = new CtField(pool.get(List.class.getCanonicalName()), "abc", evalClass);
f.setGenericSignature(getGenericSignature(relatedClass));
evalClass.addField(f);
private String getGenericSignature(Class relatedClass) throws BadBytecode {
String fieldSignature = "L" + List.class.getCanonicalName().replace(".", "/") + "<L" + String.class.getCanonicalName().replace(".", "/") + ";>;";
return SignatureAttribute.toClassSignature(fieldSignature).encode();

return SignatureAttribute.toClassSignature(fieldSignature).encode();
}
A: First, generics are not supported by Javassist.
From the Javassist documentation:
Generics
The lower-level API of Javassist fully supports generics introduced by
Java 5. On the other hand, the higher-level API such as CtClass does
not directly support generics. However, this is not a serious problem
for bytecode transformation.
The generics of Java is implemented by the erasure technique. After
compilation, all type parameters are dropped off. For example, suppose
that your source code declares a parameterized type Vector:
Vector<String> v = new Vector<String>();
String s = v.get(0);
The compiled bytecode is equivalent to the following code:
Vector v = new Vector();
String s = (String)v.get(0);
So when you
write a bytecode transformer, you can just drop off all type
parameters. Because the compiler embedded in Javassist does not
support generics, you must insert an explicit type cast at the caller
site if the source code is compiled by Javassist, for example, through
CtMethod.make(). No type cast is necessary if the source code is
compiled by a normal Java compiler such as javac.
So you can basically use the method you wrot in your question in order to add a List without generic specification and that's gonna do the work

Q: FFmpeg: what does the "global_header" flag do? According to the description, it places global headers in extradata instead of every keyframe.
But what's the actual purpose? Is it useful e.g. for streaming?
I guess that the resulting video file will be marginally shorter, but more prone to corruption (no redundancy = file unplayable if main header corrupted or only partially downloaded)?
Or maybe it somehow improves decoding a little bit? As headers are truly global and cannot change from keyframe to keyframe?
Thanks!
A: By extradata FFmpeg means out-of-band, as opposed to in-band. The behavior of the flag is format specific. This is useful for headers that are not expected to change because it reduces the overhead.
Example: for H.264 in MP4 the SPS and PPS are stored in the avcC atom. For the same H.264 stream in let's say MPEG-TS the sequences are repeated in the bitstream.

Q: Apache Arrow Java API Documentation I am looking for useful documentations or examples for the Apache Arrow API. Can anyone point to some useful resources? I was only able to find some blogs and JAVA documentation (which doesn't say much).
From what I read, it is a standard in-memory columnar database for fast analytics. Is it possible to load the data to arrow memory and to manipulate it ?
A: You should use arrow as a middle man between two applications which need to communicate using passing objects.
Arrow isn’t a standalone piece of software but rather a component used
to accelerate analytics within a particular system and to allow
Arrow-enabled systems to exchange data with low overhead.
For example Arrow improves the performance for data movement within a cluster.
See tests for examples.
@Test
public void test() throws Exception {
BufferAllocator allocator = new RootAllocator(Integer.MAX_VALUE);
File testInFile = testFolder.newFile("testIn.arrow");
File testOutFile = testFolder.newFile("testOut.arrow");
writeInput(testInFile, allocator);
String[] args = {"-i", testInFile.getAbsolutePath(), "-o", testOutFile.getAbsolutePath()};
int result = new FileRoundtrip(System.out, System.err).run(args);
assertEquals(0, result);
validateOutput(testOutFile, allocator);
}
Also Apache Parquet uses it. There are conversion examples from/to arrow objects:
MessageType parquet = converter.fromArrow(allTypesArrowSchema).getParquetSchema();
Schema arrow = converter.fromParquet(supportedTypesParquetSchema).getArrowSchema();

Q: how to secure api call from proxy I am working on some app which as API call. while i add proxy in mobile and see response in web debugging tools. I can see my api call parameters and response too.
while in others app I cant see this things and it is secured.
how can i acheive this?
A: Pictures said your API is using non-secure HTTP protocol while others app using HTTPS. The Web API should be performed via HTTPS protocol. HTTPS using SSL/TLS as secure transport layer, it means all data are encrypted before they're online. So, we don't care about any kinds of proxy

Q: Minimize Console at app startup C# I have a Console Application app, I would like to minimize (not hide permanently) the Console when i run the app, is it possible?
also, I am using a timer to run the task every 10 minutes, is it possible to minimize the console every time the app runs?
thanks!
A: The following code should do the trick. Uses Win32 methods to minimize the console window. I am using Console.ReadLine() to prevent the window closing immediately.
internal class Program
{
[DllImport("User32.dll", CallingConvention = CallingConvention.StdCall, SetLastError = true)]
[return: MarshalAs(UnmanagedType.Bool)]
private static extern bool ShowWindow([In] IntPtr hWnd, [In] int nCmdShow);
private static void Main(string[] args)
{
IntPtr handle = Process.GetCurrentProcess().MainWindowHandle;
ShowWindow(handle, 6);
Console.ReadLine();
}
}

Q: Kingfisher 3.0 iOS swift RoundCornerImageProcessor white background This is the code that I am using to set the user image which works great to actually get and set the image. I get a white outline to the picture. Any idea how to make this transparent?
let processor = RoundCornerImageProcessor(cornerRadius: 50)
self.userPhoto.backgroundColor = Colors.accent
self.userPhoto.kf.setImage(with: url, placeholder: UIImage(named: "ic_camera_alt_48pt"), options: [.processor(processor)])
Example with 50
A: The format of the original image doesn't support transparency (i.e. JPEG). You must convert the image to one that does (i.e. PNG) prior to caching.
From the Kingfisher Cheat Sheet:
By default (DefaultCacheSerializer), Kingfisher will respect the input
image format and try to keep it unchanged. However, there are some
exceptions. A common case is that when you using a
RoundCornerImageProcessor, you may always want the alpha channel. If
your original image is jpg, you may want to set the png serializer
instead:
let roundCorner = RoundCornerImageProcessor(cornerRadius: 20)
imageView.kf.setImage(with: url,
options: [.processor(roundCorner),
.cacheSerializer(FormatIndicatedCacheSerializer.png)]
)

Q: I have a .net 4.7 project but I can't add a reference to NetStandard 2.0 i have a project that is a .net 4.7. In the nuget manager, I install the .net standard 2.0 preview in this project, I can see the reference in the solution explorer, but I get an error that DateTime is definied in an assembly that is not referenced, that I have to add the reference to netstandard.dll.
I have added manually the reference to the netstandard.dll that I have in the package folder, but then I get the error that the System.boolean and other type are not definied.
So I would like to know how I could have a .net 4.7 project that use another project that is .net standard.
Thanks.
A: Until the automated tooling is shipped in an update to VS 2017 15.3 preview / .net core tooling 2.0.0 preview2, you need to include the NuGet package NETStandard.Library.NETFramework to get netstandard2.0 support in .NET Framework projects.

Q: Display woocommerce variable product price How to display woocommerce variable price for current active variation on single product page?
I use the code:
<?php
global $product;
if ($product->is_type( 'simple' )) { ?>
<p class="price"><?php echo $product->get_price_html(); ?></p>
<?php } ?>
<?php
if($product->product_type=='variable') {
$available_variations = $product->get_available_variations();
$variation_id=$available_variations[0]['variation_id']; // Getting the variable id of just the 1st product. You can loop $available_variations to get info about each variation.
$variable_product1= new WC_Product_Variation( $variation_id );
$regular_price = $variable_product1 ->regular_price;
$sales_price = $variable_product1 ->sale_price;
echo $regular_price+$sales_price;
}
?>
But it shows only lowest variable price instead of currently selected variation's price.
How can I display the current price for the active variation?
A: <?php
global $product;
if ($product->is_type( 'simple' )) { ?>
<p class="price"><?php echo $product->get_price_html(); ?></p>
<?php } ?>
<?php
if($product->product_type=='variable') {

A: So, you can just modify \your-theme\woocommerce\single-product\sale-flash.php file
Or, your can also use filter.
By the way there is more simple solution:
if ($product->is_type( 'simple' )) {
$sale_price = $product->get_sale_price();
$regular_price = $product->get_regular_price();
}
elseif($product->is_type('variable')){
$sale_price = $product->get_variation_sale_price( 'min', true );
$regular_price = $product->get_variation_regular_price( 'max', true );
}
$discount = round (($sale_price / $regular_price -1 ) * 100);
}

Q: Compute possible combinations of an equation I've got a template of equations template = (a op b) op c where the available operations op are the following: op = ['+', '-', '/', '*'].
What I want to do is to compute all the possible combinations of this equation using the operations op and the parameters a, b and c.
e.g.
(a + b) + c
(a - b) - c
(a * b) * c
(a / b) / c
(a + c) + b
(a - c) + b
(b * a) - c
...
...
...
I had a look at itertools.combinations however I am not quite sure if (or how) I can use this function in this particular context.
A: This does what you want:
import itertools
symbol = ['a', 'b', 'c']
op = ['+', '-', '/', '*']
for symbols in itertools.permutations(symbol):
for ops in itertools.product(op, repeat=2):
print "(%s %s %s) %s %s" % (
symbols[0], ops[0], symbols[1], ops[1], symbols[2])

print "(%s %s %s) %s %s" % (
symbols[0], ops[0], symbols[1], ops[1], symbols[2])
A: You need three things here:
*
*The permutations of your three variable: (a,b,c), (a,c,b), (b,c,a), etc.
*The cartesian product of your operation set with itself: (*, -), (-, +), (+, -), (+, +), etc.
*The cartesian product between the variables permutations and the previous product.
So, using the glorious itertools:
import itertools as it
vars = 'abc'
ops = '+-/*'
vars_permutations = it.permutations(vars)
op_permutations = it.product(ops, repeat=2)
for var, op in it.product(vars_permutations, op_permutations):
print('({} {} {}) {} {}'.format(var[0], op[0], var[1], op[1], var[2]))

Q: Refresh Chrome policies programmatically? I wrote a Chrome extension, that uses local storage.
When I open chrome://policy/ in the browser I can see my extension's data according to the its ID, however, when I change the value manually in the registry it DOES NOT get updated automatically. Instead I have to click on the "Reload policies" button.
My extension uses this data and has to be updated.
How can I refresh chrome policies from my code? (As if the user would click on the "Reload policies" button.)
Thanks!
A: For Windows, even if you're just managing the information in the registry and not via GPO, you force the updates to be reflected in Chrome with:
gpupdate /force

Then I have allowed the font all files by using below code:
add_filter('upload_mimes', 'add_custom_upload_mimes');
function add_custom_upload_mimes($existing_mimes) {
$existing_mimes['otf'] = 'application/x-font-opentype';
$existing_mimes['woff'] = 'application/x-font-woff';
$existing_mimes['ttf'] = 'application/x-font-ttf';
$existing_mimes['svg'] = 'image/svg+xml';
$existing_mimes['eot'] = 'application/vnd.ms-fontobject';
return $existing_mimes;
}
Now all type of font get uploaded but when I upload the .otf font it is showing me the same error.
Please help me to resolve this issue. Thanks In Advance.
A: try using
$existing_mimes['otf'] = 'font/otf';
or
$existing_mimes['otf'] = 'application/font-sfnt';

A: It's been a long time since You made this post. But I'm using a plugin called "WP Add Mime Types".
And as a value in plugin settings (Settings -> Myme Type Settings) I added this: otf = application/x-font-opentype
It's working for me :)
A: Blow is the step to resolved this issue.
Open the wp-config.php file of your WordPress installation and above the line where it says /* That's all, stop editing! Happy blogging. */ add the following code anywhere:
define('ALLOW_UNFILTERED_UPLOADS', true);
reference: https://tribulant.com/blog/wordpress/how-to-fix-sorry-this-file-type-is-not-permitted-for-security-reasons/
A: I have used following code, and it's worked properly.
add_filter('upload_mimes', 'custom_upload_mimes');
function custom_upload_mimes ( $existing_mimes ) {
$existing_mimes['ttf'] = 'application/x-font-ttf';
$existing_mimes['woff'] = 'application/x-font-woff';
$existing_mimes['woff2'] = 'application/x-font-woff2';
$existing_mimes['otf'] = 'application/x-font-otf';
return $existing_mimes;

Q: Php - Getting file size with an url I am trying to get a file size of an image from a remote url, I am trying to this like so:
$remoteUrl = $file->guid;
//remote url example: http://myApp/wp-content/uploads/2017/05/Screen-Shot-2017-05-08-at-10.35.54.png
$fileSize = filesize($remoteUrl);
But, I get:
filesize(): stat failed for
http://myApp/wp-content/uploads/2017/05/Screen-Shot-2017-05-08-at-10.35.54.png
A: You can use HTTP headers to find the size of the object. The PHP function get_headers() can get them:
$headers = get_headers('http://myApp/wp-content/uploads/2017/05/Screen-Shot-2017-05-08-at-10.35.54.png', true);
echo $headers['Content-Length'];
This way you can avoid downloading the entire file. You also have access to all other headers, such as $headers['Content-Type'], which can come in handy if you are dealing with images (documentation).

This way you can avoid downloading the entire file. You also have access to all other headers, such as $headers['Content-Type'], which can come in handy if you are dealing with images (documentation).
A: That error usually means the supplied URL does not return a valid image. When I try to visit http://myapp/wp-content/uploads/2017/05/Screen-Shot-2017-05-08-at-10.35.54.png it does not show an image in my browser. Double check that the returned URL from $file->guid; is correct.
A: You will need to try a different method, the http:// stream wrapper does not support stat() which is needed for the filesize() function.
This question has some options you might use, using curl to make a HEAD request and inspect the Content-Length header.

Q: ERROR Error: No provider for JwtHelper I'm new to Angular2 and i'm using jwthelper to encode the jwt token and extract the details.

Couldn't find a solution for the following error and show me what is incorrect here.
ERROR Error: No provider for JwtHelper!
A: This is because you are trying to inject JwtHelper in the constructor of your component/service. This is done only for providers.
According to using jwthelper in components section, you have to create a new object and use it.
In your service,
constructor(){} //remove from constructor.

Q: How to get ordered type of Map from method Collectors.groupingBy I need to separate list of data into different lists by type, for this purpose I use construction
Map<String,List<Dish>> dishMap = menu.stream()
.collect(Collectors.groupingBy(Dish::getType));
but How can I get LinkedHashMap instead HashMap from method "Collectors.groupingBy". I found some data in javadoc but I can`t get what I must to do with this method:
Map<String,List<Dish>> dishMap = menu.stream().collect(Collectors.groupingBy(
Dish::getType,
LinkedHashMap::new, ????));
what should I place in the third argument in method "groupingBy" to get what I need?

Map<String,List<Dish>> dishMap = menu.stream().collect(Collectors.groupingBy(
Dish::getType,
LinkedHashMap::new, Collectors.toList()));

Q: input[type="submit" i] - What is "i" and this syntax While inspecting an element in Chrome I stumbled across this:
input[type="submit" i]:active
It's part of Chrome's user agent stylesheet. I've been doing web development since 2002 and I've never seen or noticed this before. It doesn't even seem to match what I thought the syntax was. Is this specific to Chrome? Is there W3C documentation on it? Upon trying to mess with it, it didn't seem to be behave any differently than writing this:
input[type="submit"]:active
I've been actively searching the web and have had zero luck finding anything. If anyone knows, I'd appreciate an answer.
P.S. The only thing I could think of is that it meant, "internal," though I simply don't know.

Q: How to show md-error in material select box in angular 2? I am using reactive forms for validation in my angular 2 project. I want to highlight the fields that are invalid when 'submit' is pressed. I have achieved this in input tag by using md-Error but i am not able to do it in md-Select. Can anybody help?
Screenshot: http://i.imgur.com/uOQbwaZ.png
This is an example of md-select that i am using:
<md-select placeholder="Listing Type" formControlName='listingType' required >
<md-option *ngFor="let type of listType" [value]="type">
{{ type }}
</md-option>
</md-select>
This is the md-input that i am using:
<md-input-container class="more-width">
<input mdInput formControlName='price' required placeholder="Price">
<md-error>Please Enter Price</md-error>
</md-input-container>
This is the Validation that i am applying
this.listingForm = this.fb.group({
propertyType: ['', Validators.required]
})
A: You can show the red line below the box, but no error messages as of right now. I think it's a feature that will come soon. Issue on Github

A: you can find a good example of this validating an email address in the angular material documentation here.
A: This error has now been resolved. You just need to place the mat-error outside the mat-select and inside the mat-form-field. Here is an example
<mat-form-field appearance="fill">
<mat-label>Favorite animal</mat-label>
<mat-select [formControl]="animalControl" required>
<mat-option>--</mat-option>
<mat-option *ngFor="let animal of animals" [value]="animal">
{{animal.name}}
</mat-option>
</mat-select>
<mat-error *ngIf="animalControl.hasError('required')">Please choose an
animal</mat-error>
</mat-form-field>

Q: Django widget override template I am new at django.
I want to create a custom widget.
forms.py:
from project.widgets import MultiChoiceFilterWidget
class CustomSearchForm(FacetedSearchForm):
TEST_COLORS = [
u"Blau", u"Rot", u"Gelb"
]
color = forms.MultipleChoiceField(
label=_("Color"), choices=[(x, x) for x in TEST_COLORS],
widget=MultiChoiceFilterWidget, required=False)
widget.py:
class MultiChoiceFilterWidget(forms.widgets.CheckboxSelectMultiple):
template_name = 'project/widgets/filter.html'
option_template_name = 'ptoject/widgets/filter_option.html'
project/widgets/filter.html:
<h1>TEST</h1>
But it doesn't render the new template, instead it still renders the old way.
Can you give me some tips?
A: If you only need to change the templates, redefining a complete widget is tedious for nothing. Since the widget is passed to the field as an instance, you can instanciate the base widget you want to use and change the templates afterward.
class CustomSearchForm(FacetedSearchForm):
TEST_COLORS = [
u"Blau", u"Rot", u"Gelb"
]
color = forms.MultipleChoiceField(
label=_("Color"), choices=[(x, x) for x in TEST_COLORS],
widget=forms.widgets.CheckboxSelectMultiple, required=False)
color.widget.template_name = 'project/widgets/filter.html'
color.widget.option_template_name = 'project/widgets/filter_option.html'
If you need to pass custom data to your templates, then you will have to create a custom widget.

color.widget.option_template_name = 'project/widgets/filter_option.html'
If you need to pass custom data to your templates, then you will have to create a custom widget.
A: You will have to do the below steps to render your new widget template:
1) Add 'django.forms' to your INSTALLED_APPS;
2) Add FORM_RENDERER = 'django.forms.renderers.TemplatesSetting' to your settings.py.
More details : https://docs.djangoproject.com/en/2.0/ref/forms/renderers/#django.forms.renderers.TemplatesSetting
A: Django version < 1.11:
The widget must implement the render method in order to render a different template:
from django.utils.safestring import mark_safe
from django.template.loader import render_to_string
class MultiChoiceFilterWidget(forms.widgets.CheckboxSelectMultiple):
template_name = 'project/widgets/filter.html'
def render(self, data):
...
Do stuff with data
...
return mark_safe(render_to_string(self.template_name))
Django version 1.11:
In the renderer's documentation, we can find the following:
New in Django 1.11:
In older versions, widgets are rendered using Python. All APIs described in this document are new.
And by having a look at the widget source code and specifically on how the Input widget extends the Widget class, we can see that you would only need to customize your widget as follows:
class MultiChoiceFilterWidget(forms.widgets.CheckboxSelectMultiple):
template_name = 'project/widgets/filter.html'
Which is what you have already.

Q: Character after hyphen affects string.compare I would expect "2-" and "22" to always compare the same way, but changing the 3rd character changes the sort order.
string.Compare("2-1","22-", StringComparison.CurrentCulture) //-1
string.Compare("2-2","22-", StringComparison.CurrentCulture) //1
What on earth is happening here?
Our culture is en-US by the way.
A: As per the documentation:
Character sets include ignorable characters. The Compare(String, String, StringComparison) method does not consider such characters when it performs a culture-sensitive comparison. To recognize ignorable characters in your comparison, supply a value of StringComparison.Ordinal or OrdinalIgnoreCase for the comparisonType parameter.
In your case, the hyphen is an ignorable character. In this case it means that the middle hyphen isn't taken into account. That means it actually compares 21 and 22 to 22-, which will evaluate to -1 and 1 respectively.

Q: update or delete on table "x" violates foreign key constraint "fk_rails_5a7b40847a" on table "x" I am building a rails app (5.1.1) that has the equivalent of posts and comments linked to them.
Everything seems to be working just fine but when I try to delete a post that has comments I get this error:

The error seems pretty straight forward but I'm really new to rails and postgresql so I'm looking for some help on that!
A: It depends what you want to do with the post's comments on its deletion. In case you want to delete them on cascade, for example:
post.rb
has_many :comments, dependent: :destroy

DETAIL: Key (id)=(3) is still referenced from table "comments".
: DELETE FROM "posts" WHERE "prototypes"."id" = $1"
The error seems pretty straight forward but I'm really new to rails and postgresql so I'm looking for some help on that!
A: It depends what you want to do with the post's comments on its deletion. In case you want to delete them on cascade, for example:
post.rb
has_many :comments, dependent: :destroy
A: Update the below line in your Post model as below
has_many :comments, dependent: :destroy
You have to mention dependent: :destroy in your Post model. So when any post get to deleted by post.destroy, It deletes the all dependent records of Comment model.
Hope this will resolve your issue
A: It's because you have a constraint in your database.
I presume that the foreign key post_id in table comments must exist in the associated table posts.
That is certainly because you specify the foreign key relation in the migration with rails g model Comment post:references.
You have to specify what to do with associated models on deletion :
class Post < ActiveRecord::Base
has_many :comments, dependent: :destroy # destroy associated comments
end
Then call method post.destroy instead of post.delete on your record
See has_many for other options

Q: Failed to find build tools revision After updating Android studio version to 2.2.2 i face this error for all build tools versions. even i installed some of theme from android studio again but didn't work.
I tried all other tools versions.
Failed to find build tools revision
Update
it works good with classpath 'com.android.tools.build:gradle:2.1.0'
but with gradle:2.2.3 still got error.
A: First, try cleaning and rebuilding your project. You can find Clean project in Build tab.
If it doesn't work, use SDK Manager to install build tools version you want. Match build.gradle file to the version installed. For example, if 26.0.0 version is installed than change your build.gradle file to match the following:
android {
buildToolsVersion "26.0.0"
...
}
Check documentation for more information.
Also, check offical gradle release notes and check if you have correct versions for all programs. Upgrading Android Studio might help.

Q: Google App Engine Deploy Error Code 9 All,
I'm attempting to deploy a Google App Engine. I've gotten as far as this, but I'm not sure how to proceed.
Updating service [default]...
......failed.
ERROR: (gcloud.app.deploy) Error Response: [9] The App Engine service account does not exist for "[my-project]".
It appears that I need to create a service account for the app engine, but I'm not sure what variables it needs.
Thanks!
A: The problem is that I had deleted the "App Engine default service account".
I was able to re-add the account using this page.
On the right side of the page is a tool to "Try the API". For the appsId enter the project to be repaired and then click 'Execute'.
The tool will walk you through a series of steps and at the end repair the project.

Q: Plain Javascript: event.target : Get the next Sibling, & the first Child I have an HTML table and have set up event listeners for each row:
var greyHeadings = document.querySelectorAll(".grey");
console.log(greyHeadings);
greyHeadings.forEach(function(greyHeading){
greyHeading.addEventListener('click', function(e){
displayDescription(e, greyHeading);
});
});
The function which is called ( displayDescription ) is the following one:
function displayDescription(e, greyHeading){
var desc = e.target.parentNode.nextSibling.firstChild;
console.log(desc);
}
It does get me the correct target, but it seems that nextSibiling.firstChild does not work. I need to get to the next row (so, the sibling), and find the first td (so, the first Child), so i can add a active class to it, -in case you're wondering.
I have also created a jsfiddle: https://jsfiddle.net/7vpzLfke/
I am a beginner, so an explanation which is a little bit more detailed would be greatly appreciated!
A: You will have to use nextElementSibling instead of nextSibling, since nextElementSibling always returns an HTML Element. More on that here

Q: How to mock object which create within the test method? I have ContextListener which inject in ServletContext object for work with database. And this DBJoint object create in method which test:
@WebListener
public class ContextListener implements ServletContextListener {
@Override
public void contextInitialized(ServletContextEvent servletContextEvent) {
final ServletContext servletContext =
servletContextEvent.getServletContext();
final DBJoint joint = new DBJointHandler(
"database_scripts", "authentication_database");
servletContext.setAttribute("db", joint);
}
}
For testing servletContext.setAttribute("db", joint); I need DBJoint joint for send in setAttribute.
My test:
@Test
public void whenThen() {
final ServletContextEvent event = mock(ServletContextEvent.class);
final ServletContext context = mock(ServletContext.class);
when(event.getServletContext()).thenReturn(context);
final ContextListener listener = new ContextListener();
listener.contextInitialized(event);
DBJoint joint = ..?// how to mocking this?
verify(context).setAttribute("db", joint);
}
*
*Testing for servletContext.setAttribute("db", joint); is possibly?
*If answer "yes", how.
Thank You.
A: You can mock constructor by using power mock. Try this
DBJointHandler joint = new DBJointHandler("database_scripts", "authentication_database");
try {
PowerMockito.whenNew(DBJointHandler.class).withArguments("database_scripts", "authentication_database").thenReturn(joint);
} catch (Exception e) {
// TODO Auto-generated catch block
e.printStackTrace();

A: First you need to understand that your servletContext object is a mocked object and not a real object. The joint object is real and you don't need to mock.
You can possibly test servletContext.setAttribute("db", joint); using mockito verify
verify(servletContext).setAttribute(eq("db"), any(DBJoint.class));

Q: Java get context url in spring service without HttpServletRequest In my spring webservice I'm trying to get the url of my application like "http://localhost:8080/mycontext".
My service does not contain any HttpServletRequest var, so I can I get it ?
A: You can get the current request via the RequestContextHolder like:
ServletRequestAttributes sra = (ServletRequestAttributes)RequestContextHolder.getRequestAttributes();
HttpServletRequest req = sra.getRequest();
req.getContextPath();
req.getPathInfo();
Or you can just inject it via Spring into your service:
private @Autowired HttpServletRequest request;

Q: Should namelists be avoided in Fortran and if so what is the recommended alternative? I often use the namelist feature for flexible input of parameter lists to FORTRAN programmes, but the other day when searching to remind myself of their use I came across this statement:
It (namelist language extension to f77) has now been included in the Fortran 90 language. However, NAMELIST is a poorly designed feature and should be avoided whenever possible.
I was just wondering
*
*if this is a generally held view?
*if yes, why is this the case?
*what the suggested alternative is for parameter input? (I of course use netcdf for gridded data file input, I'm thinking of run-time parameter settings here).
A: There is no mention of namelist inefficiency and poor design whatsoever in the canonical book of Metcalf et al.: Modern Fortran Explained. https://books.google.com/books?id=V7UVDAAAQBAJ&lpg=PP1&pg=PA197#v=onepage&q=namelist%20I/O&f=false
To the contrary, I believe namelists -- especially with the added enhancements in Fortran 2003 and 2008 -- are quite useful and flexible method of data I/O.

Q: How to make quality gate pass, although new plugins are added? I added two plugins to SonarQube version 6.3.0.19869 (css and web). Now all my projects fail on their quality gate.
How can I get it to pass for the first time? I can't fix all old errors now. I want to fix only new issues.
A: Version 6.3 included functionality to backdate new issues raised on old code by rules that are newly added to your previously applied profile.
However, that functionality still misses some cases (SONAR-8737), and yours appears to be one of them.

However, that functionality still misses some cases (SONAR-8737), and yours appears to be one of them.
A: Go to http://yourserver:port/issues and try to filter out exactly those issues, that you do not want to handle for the moment (probably using the "Language" or "Creation Date" filters are a good start).
Then do a "Bulk Change" (link on top of the page) to get all of these issues out of your project's quality gate.
Depending on your quality gate, this might mean to change the status of the issues from "open" to "confirmed", change their severity, or similar.
Since this approach really depends on the quality gate configuration, it does not work in all cases.

Q: How to send json data in POST request using C# I want to send json data in POST request using C#.
I have tried few ways but facing lot of issues . I need to request using request body as raw json from string and json data from json file.
How can i send request using these two data forms.
Ex: For authentication request body in json --> {"Username":"myusername","Password":"pass"}
For other APIs request body should retrieved from external json file.
A: This works for me.
var httpWebRequest = (HttpWebRequest)WebRequest.Create("http://url");
httpWebRequest.ContentType = "application/json";
httpWebRequest.Method = "POST";
using (var streamWriter = new
StreamWriter(httpWebRequest.GetRequestStream()))
{
string json = new JavaScriptSerializer().Serialize(new
{
Username = "myusername",
Password = "password"
});
streamWriter.Write(json);
}
var httpResponse = (HttpWebResponse)httpWebRequest.GetResponse();
using (var streamReader = new StreamReader(httpResponse.GetResponseStream()))
{
var result = streamReader.ReadToEnd();

A: You can use either HttpClient or RestSharp. Since I do not know what your code is, here is an example using HttpClient:
using (var client = new HttpClient())
{
// This would be the like http://www.uber.com
client.BaseAddress = new Uri("Base Address/URL Address");
// serialize your json using newtonsoft json serializer then add it to the StringContent
var content = new StringContent(YourJson, Encoding.UTF8, "application/json")
// method address would be like api/callUber:SomePort for example
var result = await client.PostAsync("Method Address", content);
string resultContent = await result.Content.ReadAsStringAsync();
}
A: You can do it with HttpWebRequest:
var httpWebRequest = (HttpWebRequest)WebRequest.Create("http://yourUrl");
httpWebRequest.ContentType = "application/json";
httpWebRequest.Method = "POST";
ServicePointManager.SecurityProtocol = SecurityProtocolType.Tls12 | SecurityProtocolType.Tls11 | SecurityProtocolType.Tls;
using (var streamWriter = new StreamWriter(httpWebRequest.GetRequestStream()))
{
string json = new JavaScriptSerializer().Serialize(new
{
Username = "myusername",
Password = "pass"
});
streamWriter.Write(json);
streamWriter.Flush();
streamWriter.Close();
}
var httpResponse = (HttpWebResponse)httpWebRequest.GetResponse();
using (var streamReader = new StreamReader(httpResponse.GetResponseStream()))
{
var result = streamReader.ReadToEnd();

Q: Get the sum which is greater than 0 or less than 0 using MySQL I have a MySQL query that will get the sum of the amount in my column. What I found out is that there are also negative values in my data. I want to separate the sum of positive values and negative values. Can you help me on this?
I tried this query... but its giving me a Invalid use of group function.
Here's my query:
SELECT sum(AMOUNT) from deposit where type = 42 and sum(AMOUNT) > 0
A: I found the solution which was posted by someone earlier but unfortunately he deleted it(i dont know why) Thanks to that person. :)
I tried to consider the Having clause but its giving me a wrong result.
SELECT sum(CASE WHEN AMOUNT > 0 THEN AMOUNT ELSE 0 END) as Positive,
sum(CASE WHEN AMOUNT < 0 THEN AMOUNT ELSE 0 END) as Negative from deposit where type = 42

SELECT sum(CASE WHEN AMOUNT > 0 THEN AMOUNT ELSE 0 END) as Positive,
sum(CASE WHEN AMOUNT < 0 THEN AMOUNT ELSE 0 END) as Negative from deposit where type = 42
A: Whenever you have a condition on an aggregate, use having:
SELECT sum(AMOUNT) from deposit where type = 42 having sum(AMOUNT) > 0
Or if you are only interested in summing the positive values, then don't put the condition on the sum, but on the individual amount:
SELECT sum(AMOUNT) from deposit where type = 42 and amount > 0
A: Use having
SELECT sum(AMOUNT) from deposit where type = 42 and amount > 0 having sum(AMOUNT) > 0
A: You could also use a subselect:
SELECT s FROM (
SELECT SUM(amount) s FROM deposit WHERE type = 42
) R
WHERE s > 0;
See also: https://en.wikipedia.org/wiki/Having_(SQL)
A: For this type of situation we have aggregate functions having in mysql.
1) If you want to get greater than zero;
SELECT sum(AMOUNT) from deposit where type = 42 having sum(AMOUNT) > 0
2) If you want to get less than zero;
SELECT sum(AMOUNT) from deposit where type = 42 having sum(AMOUNT) < 0
If you want both in one result you can use subquery.

Q: ClassCastException after applying PathProperties I'm trying to apply some PathProperties to my Finders but I keep getting this error :
[ClassCastException: java.util.ArrayList cannot be cast to com.avaje.ebean.bean.BeanCollection]
It only happens when I have a List<...> called in my PathProperties like so :
PathProperties pathProperties = PathProperties.parse("(*,historique(*))");
List<Devi> test = Devi.find.apply(pathProperties).findList();
Where my Finder is defined like this :
public static Finder<String,Devi> find = new Finder<String,Devi>(Devi.class);
Here, the object Devi is full of public variables, that I am able to call without any issue (the PathProperties "(*)" works), but when I try to access a List of objects inside this object (here, public List<Histo> historique), it won't work. I tried, and I'm also able to access an object within the object, as long as it's not a List.
I'm kinda lost here, I don't know what I did wrong.
A: According to https://github.com/ebean-orm/ebean/issues/591 , this is a bug triggered by initializing the ArrayList. Without the initialization it will apparently work.

Q: How to make a button redirect to another page in React I have a component which has in its Class.propTypes a function onClick: onClick: PropTypes.func
In another component I'm using this component multiple times to populate a page. Each of these components have a title which when clicked should redirect to another page.
The problem I have is that it doesn't work when I click on it. It does nothing.
This is the render of the main component:
render() {
return (
<Class
title={account.AccountName}
onClick={() => "mySite/accountview?id=" + account.AccountName}
>
</Class>
...
);
}
What should I add to onClick to make it work?
A: You need use React Router.
With Link:
<Link to={`/mySite/accountview?id=${account.AccountName}`}>something</Link>
With onClick:
<button onClick={() => hashHistory.push(`/mySite/accountview?id=${account.AccountName}`)}></button>
You can use hashHistory or browserHistory :D

Q: Visual Studio keep expanding things
*
*I collapse a project in Project Explorer. Save, close Visual Studio, reopen the solution, everything is expanded.
*I collapse a method, or a region, or a comment, or whatever other piece of code. Save, close Visual Studio, reopen the solution, reopen the file, everything is expanded.
*I collapse some XAML. Save, close Visual Studio, reopen the solution, reopen the file, everything is expanded.
At first I was using Visual Studio 2015 and I had not this problem. Then it started behaving this way. Then I uninstalled VS2015, and then installed VS2017.
It keeps doing it. It doesn't happens with all the solutions or projects, by the way, and it's not consistent. In some cases it only expands all projects in the Project Explorer, in other cases it expands everything.
Any idea? What could it be?
A: Do you have check "Track Active Item in Solution Explorer" (Tools -> Options -> Projects and Solutions)?
If it's on, Solution Explorer will expand folders.

Q: Restore marker initial position and zoom level in Leaflet In Leaflet, I am trying to create a function that restores the initial position and zoom level of a layer containing coordinates. The code below
function refresh() {
map.fitBounds(coordLayer.getBounds();
}
centers the marker but is zoomed in to the maxZoom I had set:
var map = L.map('map').setView([lat, lon], 6);
L.tileLayer('http://{s}.tile.openstreetmap.org/{z}/{x}/{y}.png' {
maxZoom: 13,
minZoom: 2,

}).addTo(map);
The default zoom level on page refresh is 6, but I don't know how to create a function that centers the marker at zoom level 6.
A: Found a simple solution after reading the Documentation:
function refresh() {
map.setView([lat, lon], 6);

Q: Call to undefined function sqlsrv_connect() - Troubleshooting System Information
CMS: Wordpress
Web Server: XAMPP
PHP Version: 5.5.30

Goal
Establish MSSQL Database connection using PHP
What has been done
*
*Downloaded SQLSRV Drivers
*Copied files php_pdo_sqlsrv_55_nts.dll and php_pdo_sqlsrv_55_ts.dll to the directory C:\xampp\php\ext
*Added the following lines to the dynamic extensions part in the php.ini file: extension=php_pdo_sqlsrv_55_ts.dll and extension=php_pdo_sqlsrv_55_nts.dll
*Restarted Web Server
*Confirmed sqlsrv is listed in phpinfo()

Add to the php.ini:
extension=php_sqlsrv_55_ts.dll
or
extension=php_sqlsrv_55_nts.dll
Also, you really should be using either the Thread-Safe (_ts.dll) or Non-Thread-Safe (_nts.dll) versions of the driver, not both. I believe that, as you are using an Apache Server, you should be using the Thread-Safe versions. So you php.ini should have:

.then((resp) => resp.json())
.then(function(data) {
return data;
}).catch(function(error) {
console.log(error);// Error :(
});
}
}
export default ApiService;
A: You have async issue: both fetch and setState are async.
loadContent() {
ApiService.getTweets(topic,numberOfElements,offset).then((responseData) => {
console.log("Data is here",responseData); //<---------- HERE
this.setState({
content: responseData
}, () => {
// only now the state was updated
console.log("Data is here", this.state.content);
});
// even the nest line runs to early
console.log("Data is not here",this.state.content);
})
// the next line runs to early
console.log("Data is not here",this.state.content);
}
| Q: React can't set state I'm working in React and trying to fill a ImageGrid with data from a API. There is no problem with getting the data but somehow I cant set my state with the responseData
I can show the data while I get the response from the API but I can't set my state...
componentWillMount()
{
this.state = {
content: ''
};
this.loadContent();
}
loadContent()
{
ApiService.getTweets(topic,numberOfElements,offset).then((responseData) => {
console.log("Data is here",responseData); //<---------- HERE
this.setState({
content: responseData
});
})
console.log("Data is not here",this.state.content); //<---------- HERE
}
Here I get the data:
class ApiService {
static getTweets() {
return fetch("https://MyURL", {
method: 'get'
})
.then((resp) => resp.json())
.then(function(data) {
return data;
}).catch(function(error) {
console.log(error);// Error :(
});
}
}
export default ApiService;
A: You have async issue: both fetch and setState are async.
loadContent() {
ApiService.getTweets(topic,numberOfElements,offset).then((responseData) => {
console.log("Data is here",responseData); //<---------- HERE
this.setState({

}, () => {
// only now the state was updated
console.log("Data is here", this.state.content);
});
// even the nest line runs to early
console.log("Data is not here",this.state.content);
})
// the next line runs to early
console.log("Data is not here",this.state.content);
}
A: You want to use the set state callback as state is not set instantly.
loadContent() {
ApiService.getTweets(topic,numberOfElements,offset).then((responseData) => {
console.log("Data is here",responseData); //<---------- HERE
this.setState({
content: responseData
}, () => {
console.log("Data is here",this.state.content); //<---------- HERE
);
})
}
A: You need to implement componentDidUpdate. Don't rely on the promises to know when your component has updated. React's life-cycle will worry about that after the system has updated. See below.
From that point you can easily do something like
componentDidUpdate(prevProps, prevState) {
if(prevState.content !== this.state.content) {
console.log('I have new content!', this.state.content);
}
}
Also, you can ignore that if statement if you only have one setState() call in your component. So the short version is as follows:
componentDidUpdate(prevProps, prevState) {
console.log('I have new content!', this.state.content);
}

Q: Why do the impression counts on the AdSense app and on the site apps.AdMob.com differ? I am using admob in my app to show advertising. To check the impressions I am using AdSense app and set with my AdMob account.
When I check the impressions count on site apps.admob.com and on app AdSense impression count differ. Its almost double on AdSense app. What is the reason behind that?
A: I am seeing the same behavior.
Adsense report:
Admob report:
It seems that Admob shows adsense when it has no admob ads to show. but still it is a mystery tome why this is not indicated explicitly in the Admob website.

A: For future reference what Adsense calls impressions Admob calls it Requests. Adsense impression is counted for each ad request where at least one ad has begun to download to the user's device. But Adsence doesn't know if the ad really shows. In the other hand Admob knows when ads have been shown, and it is call Admob impression.

Q: How to measure the speed of a python function I usually write codes(functions) on www.codefights.com as a competitor.So speed is one of the important part of the code . How can i measure the speed of a certain code in python language whether it is the lambda function or a def function .
A: You can use it in ipython and use the %time to see the allocation time needed for the execution of the function :
In [1]: def function(a,b):
...: return a+b
...:
In [2]: %time function(1, 2)
CPU times: user 5 µs, sys: 0 ns, total: 5 µs
Wall time: 9.06 µs
Out[2]: 3

Wall time: 9.06 µs
Out[2]: 3
A: I usually rely on the following when I need to measure the execution time of some very specific piece of code:
https://docs.python.org/3/library/time.html
def howLong():
startTime = time.time()
time.sleep(3)
print("Time to wake up, ~3 seconds have passed!")
endTime = time.time()
howMuchTime = endTime - startTime
print(str(howMuchTime) + " sec")
if __name__ == '__main__':
import time
howLong()
Result
Time to wake up, ~3 seconds have passed!
3.013692855834961 sec
A: In 3 Step ;)
Step 1: install line_profiler
pip install line_profiler
Step 2: Add @profile to your code:
from time import sleep
@profile
def so_slow(bar):
sleep(5)
return bar
if __name__ == "__main__":
so_slow(5)
Step 3: Test your code:
kernprof -l -v your_code.py
Result
Wrote profile results to your_code.py.lprof
Timer unit: 1e-06 s
Total time: 5.00283 s
File: your_code.py
Function: so_slow at line 4
Line # Hits Time Per Hit % Time Line Contents
==============================================================
4 @profile
5 def so_slow(bar):
6 1 5002830 5002830.0 100.0 sleep(5)
7 1 2 2.0 0.0 return bar
memory_profiler
You can use memory_profiler too, Install it, add profile and call it:
pip install memory_profiler
python -m memory_profiler your_code.py
Result:
Filename: your_code.py
Line # Mem usage Increment Line Contents
================================================
4 21.289 MiB 0.000 MiB @profile
5 def so_slow(bar):
6 21.289 MiB 0.000 MiB sleep(5)
7 21.289 MiB 0.000 MiB return bar
Update:
You can use objgraph to find memory leak or draw a graph of your code:
from time import sleep
import objgraph
x = [1]
objgraph.show_backrefs([x], filename='sample-backref-graph.png')
def so_slow(bar):
sleep(5)
return bar
if __name__ == "__main__":
so_slow(5)
Result:
Reference : A guide to analyzing Python performance
A: Have a look at the timeit module in pythons standard libaray:
https://docs.python.org/2/library/timeit.html
>>> import timeit
>>> timeit.timeit('"-".join(str(n) for n in range(100))', number=10000)
0.8187260627746582
>>> timeit.timeit('"-".join([str(n) for n in range(100)])', number=10000)
0.7288308143615723
>>> timeit.timeit('"-".join(map(str, range(100)))', number=10000)
0.5858950614929199
To give the timeit module access to functions you define, you can pass a setup parameter which contains an import statement:
def test():
"""Stupid test function"""
L = []
for i in range(100):
L.append(i)
if __name__ == '__main__':
import timeit
print(timeit.timeit("test()", setup="from __main__ import test"))
A: For instance:
import timeit
def a():
return 1+1
print timeit.timeit(a, number=1000000)

Q: check if date column contains all the hours in each year I frequently need to download hourly historic data from a website in the following format
` date A B C
2011/01/01 00:00 100 200 300
2011/01/01 01:00 105 210 330
.....
2012/12/31 23:00 200 400 500'
some issue i'm having is that the online data some times misses couple hours/days per year. I need to check how many and which dates are missing to decide is the data is usable.
I normally just do df.groupby(by = df['date'].dt.yr)['dt'].count() and see if each year has 8760 (8784 for leap years) and check which days are missing manually. I wonder if anyone has had similar problem and knows how to write a piece of code to tell me which year is missing how many hours and which hours are missing.

Q: Alfresco Create User From Filter By taking reference from this post and I am successful in authenticating the user. But this post does not authenticate new users that are not present in alfresco. I have also explored SSOAuthenticationFilter.java to find how alfresco creates user when external authentication subsystem is used but not able figure out how the creation of user takes place in the mentioned subsystem. It would be great if anyone could provide the way to create and authenticate user that are not present in alfresco.
A: Which version of Alfresco do you use ?
Recent version provide a similar function, please take a look to : http://docs.alfresco.com/community/concepts/auth-basics.html
The only thing you need to need is define the header name in your global properties files.
About the new user creation, in Alfresco behaviour it's based on the synchronization.syncWhenMissingPeopleLogIn properties : http://docs.alfresco.com/community/concepts/sync-props.html
When an unknown user try to loggin Alfresco will trigger a synchronization.

Q: Custom Claim with Boolean type I'm using Visual Studio 2015 to create an ASP.NET MVC 5 app. I'm using the Identity framework to add claims to a user after authentication. It's easy enough to add claims based on the built-in ClaimTypes, but I'm having challenges adding a custom claim that's a Boolean.
I've created this static class to hold my custom claim types:
public static class CustomClaimTypes
{
public static readonly string IsEmployee = "http://example.com/claims/isemployee";
}
Then I try to add a custom claim to the ClaimsIdentity object:
userIdentity.AddClaim(new Claim(CustomClaimTypes.IsEmployee, isEmployee));
It gives this error on the line above:
cannot convert from 'bool?' to 'System.Security.Claims.ClaimsIdentity'
All the examples that I'm finding are adding strings. How do you add a bool, int, or other type? Thanks.
A: You can also pass valueType as third parameter.
userIdentity.AddClaim(
new Claim(CustomClaimTypes.IsEmployee,
isEmployee.ToString(),
ClaimValueTypes.Boolean));
so on front end you will get bool type value instead of string.

userIdentity.AddClaim(
new Claim(CustomClaimTypes.IsEmployee,
isEmployee.ToString(),
ClaimValueTypes.Boolean));
so on front end you will get bool type value instead of string.
A: The claims can only be represented as strings. Any numbers, booleans, guids, whatever all have to be strings when added to the claims collection. So ToString() it.
userIdentity.AddClaim(
new Claim(CustomClaimTypes.IsEmployee,
isEmployee.GetValueOrDefault(false).ToString()));
A: To get the correct type you want in the response, you need to overload TokenEndpointResponse
public override Task TokenEndpointResponse(OAuthTokenEndpointResponseContext context)
{
foreach (var item in context.Identity.Claims)
{
object value;
if (item.ValueType.Contains("boolean"))
value = bool.Parse(item.Value);
else
value = item.Value;
context.AdditionalResponseParameters.Add(item.Type, value);
}
return base.TokenEndpointResponse(context);
}
of course after specifying the ClaimValueTypes as mentioned in previous answers, otherwise it will identify all fields as string type.

Q: Rvalue to lvalue conversion? Why it is not possible to convert rvalues to lvalues? It is possible to do a conversion in the opposite direction though. Technically rvalues do have a memory address, isn't it?
A: It is rather straightforward to write a template function unmove(), that does the opposite of std::move():
template<class T> T& unmove(T&& t) { return t; }
Please note that, according to the standard since C++11:
a temporary bound to a reference parameter in a function call exists until the end of the full expression containing that function call: if the function returns a reference, which outlives the full expression, it becomes a dangling reference.
So it is safe to use unmove() within a single full expression, but after the expression has been fully evaluated, the temporaries go away.
My common use for unmove() is to call functions / methods, that return values through references, when I don't need those values.

My common use for unmove() is to call functions / methods, that return values through references, when I don't need those values.
A: You can:
int&& x = 3;
x is now an lvalue. A so called 'rvalue-reference' can bind to a temporary,
but anything with a name is an lvalue, so you need to forward<>() it if you need it's rvalueness back.
Note that by binding a temporary to a rvalue-reference (or a const reference) you extend its lifetime. Technically a cast is possible,
but not recommended, since temporaries have short lifetime, so you
typically get a dangling reference.
A: Correct an anwer above.
int&& x = 3;
x is 'rvalue-reference'. See

Q: New line for ngbpopover text I am using angular 2 and ng bootstrap popover feature. Following is my html. I have infoIconText variable that has some new line \n character. However I am still unable to see the new line when I see the popover text. How can I style the popover text? Any suggestions?
<i class="fa fa-info-circle" ngbPopover="{{infoIconText}}" triggers="mouseenter:mouseleave" aria-hidden="true"></i>
My infoIconText is as follows:
this.infoIconText = "This is line 1." +
"\nThis is line2";
A: I was able to solve this issue by creating a template and referencing that template.
<ng-template #popContent>Line1<br>Line2</ng-template>
<i class="fa fa-info-circle info-icon-background popover-content" [ngbPopover]="popContent" placement="top" triggers="mouseenter:mouseleave" aria-hidden="true"></i>

Q: Angular Firebase Database Querying This is my .ts file
import { Component, OnInit } from '@angular/core';
import { AngularFireDatabase, FirebaseListObservable, FirebaseObjectObservable } from 'angularfire2/database';
@Component({
selector: 'app-candidate-reg-success',
templateUrl: './candidate-reg-success.component.html',

})
export class CandidateRegSuccessComponent implements OnInit {
constructor() {
debugger;
const rootRef=firebase.database.ref();
const mail=rootRef.child('candidates_list').orderByChild('email').equalTo('[email protected]');
console.log(mail);
}
ngOnInit() {
}
}
I am trying to query the user from candidates_list table which has the email address [email protected].
But I am unable to console it. It shows a error like
Property 'ref' does not exist on type 'typeof database'.
Any solution to query angular firebase database?
A: you need to inject the AngularFirebaseData in constructor and change the code and try again
import { Component, OnInit } from '@angular/core';
import { AngularFireDatabase, FirebaseListObservable,
FirebaseObjectObservable } from 'angularfire2/database';
@Component({
selector: 'app-candidate-reg-success',

export class CandidateRegSuccessComponent implements OnInit {
constructor(public db: AngularFireDatabase) {
debugger;
db.list('/candidates_list', ref => ref.orderByChild('email').equalTo('[email protected]'));
}
ngOnInit() {
}}

Q: How to use the Google satellite view as tile in leaflet with R Many questions seem similar to mine, I could not however find a fitting answer for R.
So far, I use the awesome R leaflet (and ggmap) package that way:
library(ggmap)
library(leaflet)
coord <-geocode('New York')
map.city <- leaflet() %>%
addTiles('http://{s}.tile.thunderforest.com/transport/{z}/{x}/{y}.png?apikey=68c4cd328d3b484091812a76fae093fd') %>%
setView(coord$lon, coord$lat, zoom = 11)
But what if I want as a map the Google satellite?
I went through this post
https://stackoverflow.com/questions/9394190/leaflet-map-api-with-google-satellite-layer#=
but don't understand how to use the googleSat function defined there.
A: To use the actual Google Maps (which comes with satellite view) you can use my googleway package
library(googleway)
apiKey <- 'your_api_key'
mapKey <- 'your_map_key'
newYork <- google_geocode(address = "New York", key = apiKey)
google_map(location = as.numeric(newYork$results$geometry$location),
key = mapKey)
The vignette has more examples of what you can do with the maps.

A: If it has to be google satellite imagery you could use the googleway package. If other satellite imagery is ok, you can use "Esri.WorlImagery" with or without "CartoDB.PositronOnlyLabels" in leaflet:
library(ggmap)
library(leaflet)
coord <-geocode('New York')
map.city <- leaflet() %>% addProviderTiles('Esri.WorldImagery') %>%
setView(coord$lon, coord$lat, zoom = 11)
map.city %>% addProviderTiles("CartoDB.PositronOnlyLabels")

Q: named docker volume not updating using docker-compose I'm trying to have one service to build my client side and then share it to the server using a named volume. Every time I do a docker-compose up --build I want the client side to build and update the named volume clientapp:. How do I do that?
docker-compose.yml
version: '2'

WORKDIR /usr/src/app
COPY package.json /usr/src/app
RUN npm install

# builds my application into /client

A: Imagine you shared your src folder like this :
...
volumes:
- ./my_src:/path/to/docker/src
...
What worked for me is to chown the my_src folder :
chown $USER:$USER -R my_src
It turned out some files were created by root and couldn't be modified by docker.
Hope it helps !

A: By definition, a volume is the persistent directories that docker won't touch other than to perform an initial creation when they are empty. If this is your code, it probably shouldn't be a volume.
With that said, you can:
*
*Delete the volume between runs with docker-compose down -v and it will be recreated and initialized on the next docker-compose up -d.
*Change your container startup scripts to copy the files from some other directory in the image to the volume location on startup.
*Get rid of the volume and include the code directly in the image.
I'd recommend the latter.

Q: Docker and Chromium net::ERR_NETWORK_CHANGED I have an AngularJS application that does an ajax call but it results in a chromium error:
net::ERR_NETWORK_CHANGED
I tried to disable any adapters that I don't need. I have multiple ones and multiple dockers containers running.
I disabled ipv6 on each adapter. I don't use any proxy and use default Chromium browser without any addon nor browser profile.
Disabled Wifi interface, only using ethernet.
Any idea how to fix this?
A: I was constantly getting ERR_NETWORK_CHANGED.
This is what finally worked for my current browsers:
Chromium, Opera and FlashPeak Slimjet.
sudo service docker stop
The following actions did not solve my issue:
*
*Checked modem, router, and cables to isolate the issue.
*Disabled IPv6 from my wired Network
*Commands:
sudo sysctl -w net.ipv6.conf.default.disable_ipv6=1
sudo sysctl -w net.ipv6.conf.all.disable_ipv6=1
After I stopped Docker, I am not getting any more console errors.
I hope this can help someone saving hours of annoying troubleshooting.

A: sudo service docker stop
But this is not a solution because I need docker in my daily work.
So I found out that docker networks cause this problem
docker network prune helped me
Or try to delete one by one except of none, bridge, host
A: Based on the original answers, I want to go into more detail what fixed it in my case.
Stopping the docker service sudo service docker stop in my case fixed the issue.
The underlying issue one of my docker-compose setups having restart=always.
Unfortunatly I had a bug causing a container to terminate and restart. This restart caused the network change.
It is determinable by running docker ps and noticing the container restarted.
I fixed the problem and ran docker-compose down for my docker compose setup. Both actions would fix it independently.
Furthermore a Bugreport for chromium exists regarding this issue, but it has the state wontfix.

Q: Python + OpenCV - Copying an image to some directory I would like to copy some images to some directory, rather than cv2.imwrite the images. The reason is that when I use cv2.imwrite in OpenCV, I get images that are larger than the original ones, apart from that I can see that some images are being rotated.
Would that be possible in Python + OpenCV, since I don't want any operation to be made on the original image, which cv2.imwrite seems to be doing?
Thanks.
A: You don't need opencv to do this. You can use the shutil library.
import shutil
shutil.copyfile('path/to/1.jpg', 'new/path/to/1.jpg')
Note that the destination path must specify the filename too. If you don't want this, you can use shutil.copy2 which lets you specify a directory as the destination.
shutil.copy2('path/to/1.jpg', 'new/path/to/dir')

Q: Constexpr for creating objects I'm trying to figure out if there is a performance gain of creating objects with constexpr instead of normally.
Here is the code snippet for constexpr.
class Rect
{
const int a;
const float b;
public:
constexpr Rect(const int a,const float b)
: a(a),b(b){}
};
int main()
{
constexpr Rect rect = Rect(1,2.0f);
}
And without constexpr.
class Rect
{
int a;
float b;
public:
Rect(int a, float b)
: a(a),b(b){}
};
int main()
{
Rect rect = Rect(1,2.0f);
}
I was expecting there will be a lot less code for constexpr since the memory should be initialized at compile-time.
Am I using constexpr properly? And if that is not true, can you use constexpr to create the objects at compile-time and then use them without any runtime overhead?
Thanks!
A: It turned out that I had some headers included which were responsible for the similarity of the code.
The answer is that there is a big difference between both cases.
When compiling without optimizations, there is a substantial difference in the generated code...

Q: Xamarin.Forms: Press back button from code Is there a way in Xamarin.Forms to press the back button from code? I tried to call OnBackButtonPressed and SendBackButtonPressed but this does not work. The OnBackButtonPressed Event is called but the back action does not perform.
Call OnBackButtonPressed:
if (_currentQuestionnaireGroup != null)
await RefreshDataAsync();
else
{
App.QuestionnaireOverviewPage.IsDirty = true;
this.OnBackButtonPressed();
}
Event:
protected override bool OnBackButtonPressed()
{
if (_questionnaireHandler != null)
App.QuestionnaireOverviewPage.IsDirty = true;
return true;
}
A:
Sorry for the poor english
In your Event, change return true; for return base.OnBackButtonPressed();.
When you return true, the action 'back' is canceled at device.

Q: Disable warning "Access can be package-private" for @Transactional methods I have several public methods annotated with @Transactional and IntelliJ shows the warning that they can be package-private or private.
@Transactional
public void doSomething() {
///body
}
Since methods annotated with @Transactional should be public, how can I disable in IntelliJ this inspection/warning only for those methods?
A: Sadly, it isn't possible to make all methods annotated with @Transactional clear the warning, although it is possible to add @SuppressWarnings("WeakerAccess") to make the warning go away.Alternatively, you can disable this inspection altogether in IntelliJ IDEA by going to File→Settings→Editor→Inspections.
In the list show in this view you will want to navigate through the subcategories: Java→Declaration redundancy and uncheck the checkbox called "Declaration access can be weaker" that will be available then. If you wish to disable this for future projects, choose the profile "Default" from the dropdown menu labelled "Profile", otherwise, just do this for "Project Default".

The best solution I have is to bypass cudnn by add in the .theanorc:
[dnn]
enabled = False
but at the price of the decreased computation speed
| Q: Theano 0.10: Can not use cuDNN on context None: cannot compile with cuDNN I just updated theano to 0.10 version with pip:
pip install --no-deps git+https://github.com/Theano/Theano.git#egg=Theano
But it cannot be imported successfully, with the error message as follows:
Can not use cuDNN on context None: cannot compile with cuDNN.
We got this error: c:\users\yl~1\appdata\local\temp\try_flags_jbgv_m.c:4:19:
fatal error: cudnn.h: No such file or directory compilation terminated.
Mapped name None to device cuda: GeForce 940M (0000:01:00.0)
I haven't configured theano to use cudnn. I feel theano should works without it.
My .theanorc is:

Q: Kafka multiple topic consume consumer.subscribe(Pattern.compile(".*"),new ConsumerRebalanceListener() {
@Override
public void onPartitionsRevoked(Collection<TopicPartition> clctn) {
}
@Override
public void onPartitionsAssigned(Collection<TopicPartition> clctn) {
}
});
How to consume all topics with regex in apache/kafka?
I tried above code, but it didn't work.
A: For regex use the following signature
KafkaConsumer.subscribe(Pattern pattern, ConsumerRebalanceListener listener)
E.g. the following code snippet enables the consumer to listen to all topics with prefix my_topics_
ConsumerRebalanceListener listener = new ConsumerRebalanceListener() {
@Override
public void onPartitionsRevoked(Collection<TopicPartition> arg0) {
// Don't need it now.
}
@Override
public void onPartitionsAssigned(Collection<TopicPartition> arg0) {
// Don't need it now.
}
};
pattern = Pattern.compile("my_topics_.*");
kafkaConsumer.subscribe(pattern, listener);

Q: How to reason or make inferences in Neo4j? I created a semantic Graph in Neo4j. Is there any possibility to use an OWL reasoner in Neo4j? Or any inference engine?
Though it has been mentioned here i can't find any solution or API for this.
Thankful for any advice!
A: Maybe you want to see this:
click here
I quoted this from that link:
Your main task if you want to use reasoners over a neo4j database is going to be to suck data out of neo4j, and format it as a set of RDF triples. You can then put those RDF triples into a Jena Model. When you have that jena model in memory, you can use existing jena APIs to use reasoners with that model

A: My research in this area in progress, please watch here to see latest article draft, there is special section Inference on graph.
I'm looking on neo4j -> Prolog -> neo4j approach: (a)-[b]->(c) graph can be expressed as b(a,c) predicate, so export your .db into .pl and query in SWI Prolog for example. But the most complex thing: how to do some (direct) reasoning for backward import into neo4j.
I'm thinking about applying YieldProlog with direct traversal over neo4j db using BOLT prolotocol. I plan to add special mods for Yield method to specially process labels and attributes of graph elements, so my knowledge bases going to be described is neo4j databases by design.
A: If you're looking for practical inference over graph data you should take a look at TypeDB, it has a reasoning engine built in. You can define your reasoning logic using rules in TypeQL.
P.S. I work for Vaticle, the company who builds TypeDB ;)

Q: Wildcard in JsonPath I am parsing a JSON like below:
jobs1: [
{
request: {
body: {
jobID: "79ceeeff-53b9-4645-80bd-95dfca6fe1e9",
...
jobs2: [
{
request: {
body: {
jobID: "60e7c286-f936-4f96-87bc-6bd55f107514",
And looking for a way to use wildcards in the JSON path.
I am using the RestAssured framework in Java. After executing the code like below:
List<String> ids = get("/state/").path("*.request.body.jobID");
System.out.println(ids);
I expect to get:
[79ceeeff-53b9-4645-80bd-95dfca6fe1e9, 60e7c286-f936-4f96-87bc-6bd55f107514]
But instead I get an exception:
java.lang.IllegalArgumentException: Invalid JSON expression:
Script1.groovy: 1: unexpected token: *. @ line 1, column 27.
*.request.body.jobID
^
I have looked through these tutorials, but nothing seemed to work for me:
https://github.com/json-path/JsonPath
http://goessner.net/articles/JsonPath
How do I correctly use the wildcards in JsonPath?
A: GOTO http://jsonpath.herokuapp.com/
And give input like green box in the given image.
Your pattern should be like below
*.[*].request.body.jobID
Your JSON should be like below
{
jobs1: [{

Q: How to handle media queries in HTML emails in Gmail? I send responsive HTML emails with my website, with media queries, but in Gmail / Inbox, max-width in the media query refers to the browser viewport, instead of the HTML email.
So, on every other mail client, my emails switch to mobile display under 600px, in Gmail / Inbox, this comportement is broken.
Do you have a solution to make the media query take as viewport the mail viewport instead of the browser viewport ?
A: *
*Recommended approach: <meta name=viewport content="width=device-width, initial-scale=1">
*Avoid minimum-scale, maximum-scale, user-scalable.

Q: Permanent mount volume via sshfs Sierra I am trying to permanently mount a volume via sshfs on mac. I have tried to follow the instructions in how-to-get-automount-and-sshfs-osxfuse-working-with-yosemite (Although I have Sierra, I couldn't find instructions for it so I thought to give it a try with Yosemite instructions). However I get stuck at this step:
If you do not see mount_sshfs, then you need to do this step. This
is a critical step because it is easily forgotten and may create
headaches. sudo ln -s $(which sshfs) /sbin/mount_sshfs.
Here is the error:

Q: From SKLearn to Keras - What is the difference? I'm trying to go from SKLearn to Keras in order to make specific improvements to my models.
However, I can't get the same performance I had with my SKLearn model :
mlp = MLPClassifier(
solver='adam', activation='relu',
beta_1=0.9, beta_2=0.999, learning_rate='constant',
alpha=0, hidden_layer_sizes=(238,),
max_iter=300
)
dev_score(mlp)
Gives ~0.65 score everytime
Here is my corresponding Keras code :
def build_model(alpha):
level_moreargs = {'kernel_regularizer':l2(alpha), 'kernel_initializer': 'glorot_uniform'}
model = Sequential()
model.add(Dense(units=238, input_dim=X.shape[1], **level_moreargs))
model.add(Activation('relu'))
model.add(Dense(units=class_names.shape[0], **level_moreargs)) # output
model.add(Activation('softmax'))
model.compile(loss=keras.losses.categorical_crossentropy, # like sklearn
optimizer=keras.optimizers.Adam(lr=0.001, beta_1=0.9, beta_2=0.999, epsilon=1e-08, decay=0.0),
metrics=['accuracy'])
return model
k_dnn = KerasClassifier(build_fn=build_model, epochs=300, batch_size=200, validation_data=None, shuffle=True, alpha=0.5, verbose=0)
dev_score(k_dnn)
From looking at the documentation (and digging into SKLearn code), this should correspond exactly to the same thing.
However, I get ~0.5 accuracy when I run this model, which is very bad.
And if I set alpha to 0, SKLearn's score barely changes (0.63), while Keras's goes random from 0.2 to 0.4.
What is the difference between these models ? Why is Keras, although being supposed to be better than SKLearn, outperformed by so far here ? What's my mistake ?
Thanks,

Q: Add active class to child element I am beginner with Vue.js (and bootstrap-vue) and I want to create tabs (like here)
<b-nav class="nav-tabs">
<b-nav-item v-bind:active=true v-bind:class="{ active : tab === 1 }" v-on:click="tab = 1">Link 1</b-nav-item>
<b-nav-item v-bind:class="{ active : tab === 2}" v-on:click="tab = 2">Link 2</b-nav-item>
<b-nav-item v-bind:class="{ active : tab === 3}" v-on:click="tab = 3">Link 3</b-nav-item>
</b-nav>
But when I click on second link it doesn't change active=true (and active=false on first button). I tried
v-on:click:active=true
but it doesn't work. It works fine with tabs, but not with navs (e.g. https://bootstrap-vue.github.io/docs/components/tabs). Any idea?
Added:
Vue code:
import Vue from 'vue';
import BootstrapVue from 'bootstrap-vue'
Vue.use(BootstrapVue);
new Vue({
el: '#app',
data: {
tab: 1
},
});
A: Not familiar with bootstrap-vue, but I just did a bit of toying in their playground, and what you need to bind is the active property, bootstrap takes cares of the styles from that.
In other words, this seems to work:
<b-nav class="nav-tabs">
<b-nav-item :active="tab === 1" @click="tab = 1">Link 1</b-nav-item>
<b-nav-item :active="tab === 2" @click="tab = 2">Link 2</b-nav-item>

A: Not familiar with bootstrap-vue, but I just did a bit of toying in their playground, and what you need to bind is the active property, bootstrap takes cares of the styles from that.
In other words, this seems to work:
<b-nav class="nav-tabs">
<b-nav-item :active="tab === 1" @click="tab = 1">Link 1</b-nav-item>
<b-nav-item :active="tab === 2" @click="tab = 2">Link 2</b-nav-item>
<b-nav-item :active="tab === 3" @click="tab = 3">Link 3</b-nav-item>
</b-nav>
A: First of all you might need to add quotation marks in v-bind:active="true"but here is the general fiddle. I am not using bootstrap-vue component, but it shouldn't be that difficult
A: you can proceed like this
<b-nav class="nav-tabs">
<b-nav-item exact-active-class="active" to="/link-1">Link 1</b-nav-item>
<b-nav-item exact-active-class="active" to="/link-2">Link 2</b-nav-item>
<b-nav-item exact-active-class="active" to="/link-3">Link 3</b-nav-item>
</b-nav>
property exact-active-class: <router-link> prop: Configure the active CSS class applied when the link is active with exact match. Typically you will want to set this to class name 'active'

Q: React-Native: How to increase space between text and underline I have followed styles:
const styles = StyleSheet.create({
title: {
textDecorationLine: 'underline',
textDecorationStyle: 'solid',
textDecorationColor: '#000'
}
});
and it creates the underline for my content into some Text component. But it seems that this underline is too close to the text decorated with it.
Can I increase this distance in some how?
Thank you for helping!
A: *
*Wrap your Text in a View that has a style containing borderBottomWidth: 1 or whatever you want the thickness to be.
*Give your Text a lineHeight to adjust the spacing between the border and the content. If you have multiple lines of text, then using paddingBottom would also work.
Simple as that really. Bear in mind the View border will stretch to include any padding on the View itself.

A: As of now that is not possible in React Native, cause it is also not supported in web apps i.e Css.
Link here
But there is a work around to this.
Create react View wrapper over the Text you want to adjust the underline. And then add borderBottomWidth to View and adjust the distance of underline from Text paddingBottom.
const styles = StyleSheet.create({
viewStyle : {
borderBottomWidth: 10, // whatever width you want of underline
}
title: {
paddingBottom: 4, // Adjust the distance from your text view.
}
});
Add the viewStyle to your parentView.
Hope that helps!
A: According to me, the best possible way to do this is to add a <View /> (without content) after the <Text> and give top-border as you want your underline to be.
For example:
<Text style={{ color: 'blue' }}>Categories</Text>
<View style={{
height: 0, // height is '0' so that the view will not occupy space
width: 100, // as much as you want to 'Stretch' the underline
borderTopColor: 'blue',
borderTopWidth: 2, // 'Thickness' of the underline
marginTop: 15 . // 'Gap' between the content & the underline
}} />
REMEMBER: This will work if the parent of your Text has flexDirection: 'column' (which is default value). But if it has flexDirection: 'row', wrap both the Text & View (i.e. underline) in another view like <View>...</View> so the items will be arranged in a column.

Q: Change behaviour of help text in django form globally I want to take advantage of the default help text in django, but I don't like the way it's handled. I want to have:
<tr><label>djangolab</label><input>djangoinput</input><span>djangohelp></span><span class='onhovershowhelp'>?</span>
The last element is not provided by default. CSS on hover on '?' will change visibility for the help text span from hidden to visible.
I want things to work out of the box so '{{form}}' will display as I want for any model form. So I want globally:
*
*Help text span by default with some attributes(z=1, hidden)
*Add another span to form row.
I don't want to do this for every model form/field etc, use loops in the template and manually build this etc...
A: Got it. Have all forms inherit something like this (that _html_output call is the hidden implementation detail taken directly from django's source code):
import django.forms
class GenericForm(django.forms.ModelForm):
def as_table(self):
return self._html_output(
normal_row='<tr%(html_class_attr)s><th>%(label)s</th><td>%(errors)s%(field)s%(help_text)s</td></tr>',
error_row='<tr><td colspan="2">%s</td></tr>',
row_ender='</td></tr>',
help_text_html='<a class="helptext">?<span>%s</span></a>',
errors_on_separate_row=False)
return html
And some CSS to accompany this:
.helptext {
margin: 5px;
color: blue;
}
a.helptext span {
display:none;
width: 30em;
text-align: justify;
z-index:1;

Q: Docker how to use boolean value on spec.container.env.value Is there a way to pass a boolean value for spec.container.env.value ?
I want to override, with helm, a boolean env variables in a docker parent image (https://github.com/APSL/docker-thumbor) : UPLOAD_ENABLED
I made a simpler test
If you try the following yaml :
apiVersion: v1
kind: Pod
metadata:
name: envar-demo
labels:
purpose: demonstrate-envars
spec:
containers:
- name: envar-demo-container
image: gcr.io/google-samples/node-hello:1.0
env:
- name: DEMO_GREETING
value: true
And try to create it with kubernetes, you got the following error :
kubectl create -f envars.yaml
the error :
error: error validating "envars.yaml": error validating data: expected type string, for field spec.containers[0].env[0].value, got bool; if you choose to ignore these errors, turn validation off with --validate=false
with validate=false
Error from server (BadRequest): error when creating "envars.yaml": Pod in version "v1" cannot be handled as a Pod: [pos 192]: json: expect char '"' but got char 't'
It doesn't work with integer values too

A: Try escaping the value. The below worked for me:

In my example, one is hardcoded, and the other comes from an env var.
env:
- name: MY_BOOLEAN
value: 'true'
- name: MY_BOOLEAN2
value: '${MY_BOOLEAN2_ENV_VAR}'
So basically, I wrap single quotes around everything, just in case.
WARNING: Dont use hyphens in your env var names, that will not work...
A: if you are the helm chart implementer, just quote it
data:
# VNC_ONLY: {{ .Values.vncOnly }} <-- Wrong
VNC_ONLY: "{{ .Values.vncOnly }}" # <-- Correct
A: spec.container.env.value is defined as string. see here:
https://kubernetes.io/docs/api-reference/v1.6/#envvar-v1-core
You'd have to cast/convert/coerse to boolean in your container when using this value
A: From command line you can also use
--set-string
instead of
--set
and you will be able to pass value without escaping
for instance:
--set-string "env.my-setting=False"

Q: O notation of a Loop for(int i = 0; i < n; i++) {
for(int j = 0; j < i; j++) {
O(1);
}
}
here the func is n * (n+1) / 2 but what if the outerloop condition is i < log(n)? I have problems with loops that relates on each other.
A: You just have to count the total number of iterations:
1 + 2 + 3 + .. + n - 1 = n * (n - 1) / 2
as you correctly inferred. When you replace n with log(n), just do the same in the final formula, which then becomes log(n) * (log(n)+1) / 2, or in Big-O notation, O((log(n))^2).

A: If the condition of the outer loop is changed to i < log(n) then the overall complexity of the nested two-loop construct changes from O(n2) to O(log(n)2)
You can show this with a simple substitution k = log(n), because the complexity of the loop in terms of k is O(k2). Reversing the substitution yields O(log(n)2).
A: For nested for loops (when using the O notation, ofc) you can multiply the worst-case scenario of all of them. If the first loop goes to x and you have a nested loop going to i (i being at worst-case x) then you have a run-time complexity of O(x^2)

Q: ModuleNotFoundError: No module named 'tensorflow.tensorboard.tensorboard' There seems to be a problem with recent TensorFlow build. The TensorBoard visualization tool would not run when it is compiled from sources to use with GPU. The error is as follows:

from tensorflow.tensorboard.tensorboard import main
ModuleNotFoundError: No module named 'tensorflow.tensorboard.tensorboard'

Would appreciate any help!

python -m tensorboard.main --logdir=/path/to/logs
A: Okay, I've found a solution that works and also received some explanation from tensorflower on github.
There might be an issue with tensorboard when compiling tensorflow from sources because tensorboard is now removed to a separate repo and is not a part of tensorflow. The tensorflower said the docs will be updated eventually, but I figured a workaround for the impatient (like myself).
Edit tensorboard file inside tensorflow/bin (/home/gpu/anaconda3/envs/tensorflow/bin/tensorboard in my case) and replace
from tensorflow.tensorboard.tensorboard import main
by
from tensorflow.tensorboard.main import *
Now tensorboard should run from console as usual.
A: Tensorboard ships with tensorflow. If you are unable to run using tensorboard command, try below approach. tensorboard.py might have been moved to different directory.
Try searching for tensorboard.py in the tensorbard directory where tensorflow is installed. Go to the path and use following line for visualization:
python tensorboard.py --logdir=path
A: You should priorly launch
pip install tensorflow.tensorboard

Q: How do I access an attribute from a counted resource within another resource? I'm using Terraform to script an AWS build. I'm spinning up a number of instances across multiple availability zones, in this example, 2:
resource "aws_instance" "myinstance" {
count = 2
ami = "${var.myamiid}"
instance_type = "${var.instancetype}"
availability_zone = "${data.aws_availability_zones.all.names[count.index]}"
# other details omitted for brevity
}
I now need to assign an Elastic IP to these instances, so that I can rebuild the instances in the future without their IP address changing. The below shows what I'd like to do:
resource "aws_eip" "elastic_ips" {
count = 2
instance = "${aws_instance.myinstance[count.index].id}"
vpc = true
}
But this errors with:
expected "}" but found "."
I've also tried using lookup:
instance = "${lookup(aws_instance.sbc, count.index).id}"
but that fails with the same error.
How can I go about attaching Elastic IPs to these instances?
A: A bit more playing around and I've found the answer - you can index into the "splat" syntax:
instance = "${aws_instance.myinstance.*.id[count.index]}"

instance = "${aws_instance.myinstance[count.index].id}"
vpc = true
}
But this errors with:
expected "}" but found "."
I've also tried using lookup:
instance = "${lookup(aws_instance.sbc, count.index).id}"
but that fails with the same error.
How can I go about attaching Elastic IPs to these instances?
A: A bit more playing around and I've found the answer - you can index into the "splat" syntax:
instance = "${aws_instance.myinstance.*.id[count.index]}"
A: This works for me,
instance = aws_instance.myinstance.*.id
A: Please go through terraform interpolation - element list index
element(list, index) - Returns a single element from a list at the given index. If the index is greater than the number of elements, this function will wrap using a standard mod algorithm. This function only works on flat lists. Examples:
element(aws_subnet.foo.*.id, count.index)
So in your case, the code will be:
instance = "${element(aws_instance.myinstance.*.id, count.index}"
A: Other answers already pointed out that counted elements must be accessed via indexes. I like to add that I encountered the error
Because aws_instance.some-resource has "count" set, its attributes must be accessed on specific instances.
although I had already fixed that particular line. The error kept showing up, mentioning a line with some code segment that was not even present any longer in my code.
I was able to resolve this by fixing all places where I had not accessed a specific instance (which were also mentioned in other errors). In my case, an output section was not adapted previously. Only then all errors disappeared all of a sudden.
A: try using aws_instance.jserver[count.index].id
e.g. of ec2 instance and volume attachment is
resource "aws_instance" "jserver"{
count=3
}
resource "aws_volume_attachment" "j_ebs_att" {
count = 3
...
instance_id = aws_instance.jserver[count.index].id
}
A: I know you are using older version of terraform but I still want to add just in case someone is struggling with the same issue with terraform 0.12. For terraform version 11 the syntax is totally different from version v12. As you can see it's only the interpolation that should be removed. From your syntax and the various response provided.
version 11:
instance = "${aws_instance.myinstance.*.id[count.index]}"
version 12
instance = aws_instance.myinstance.*.id[count.index]

Q: On click stopPropagation while keeping bootstrap collapse behavior I have a bootstrap list-group-item with a badge as follows:
<a class="list-group-item list-group-item-action" href="#" revision="211147" id="commit0">
<span class="badge collapsed" id="badge0" data-toggle="collapse" data-target="#ul0" >
changed files:1
</span>
<ul class="list-group changed-files-list collapse" id="ul0" aria-expanded="false" style="height: 0px;">
<li class="list-group-item changed-file">
release.groovy
</li>
</ul>
</a>
It contains a collapsed ul that is targeted by the badge.
At the same time, when clicked, the a element is selected(as it is part of a list-group with multiple selection possible).
I try to insert this bit of code:
$('.badge').on('click', function(e){
//$('#'+this.id).click();
e.stopPropagation();
});
so that when clicking on the badge the a element is not selected.
If I use this code the ul element is not being shown. I guess bootstrap uses the on click function and so it has something to do with my function overriding the bootstrap one.
How can I stop propagation while keeping the collapse behavior?
A: I found the solution by using bootstrap's collapse function:
$('.badge').click( function(e){
$('#ul'+this.id.substring(5)).collapse("toggle");
e.stopPropagation();
});

Q: How to execute a MySQL function in a Knex query? I have a BINARY field in my table which I usually grab like this:
SELECT HEX(users.id) AS id FROM users WHERE username = ?
I recently started using Knex because I need to be able to dynamically generate WHERE clauses from objects. Here's what I tried:
knex('users').select('HEX(users.id) AS id)').where(filter);
Here's the query it generates:
select `HEX(users`.`id)` as `id` ....
And then I tried this:
knex('users').select('HEX(`users`.`id`) AS id').where(filter);
And it comes up with this:
select `HEX(``users```.```id``)` as `id` ....
How do I execute HEX() without it being mistaken for a column name?
A: With knex letting to do quoting of identifiers it would look like this:
knex('users').select(knex.raw('HEX(??) AS id', ['users.id'])).where(filter);

Q: Rotated elements overlap each other Is there a way to fix this, when I rotate 2 elements, they overlap each other because the width and height don't swap.
Thank you
https://jsfiddle.net/aez4uc3u/
a {
display: block;
transform: rotate(-90deg);
}
<div>
<a href="#">This is the first link</a>
<a href="#">This is the second link</a>
</div>
A: Rotate the parent.
a {
display: block
}
div {
transform: rotate(-90deg);
}
<div>
<a href="#">This is the first link</a>
<a href="#">This is the second link</a>
</div>
Positioning the div as you might like will take additional transforms and, perhaps, adjusting the transform-origin property.
You shoud also be aware that transform is purely visual. It does not actually affect the positioning or margins of elements.

Q: What's the difference between git stash save and git stash push? When should I use git stash save instead of git stash push and vice-versa?
A: git stash save accepts a single non-option argument — the stash message.
git stash push accepts the message with option -m and accepts a list of files to stash as arguments.
| Q: What's the difference between git stash save and git stash push? When should I use git stash save instead of git stash push and vice-versa?
A: git stash save accepts a single non-option argument — the stash message.
git stash push accepts the message with option -m and accepts a list of files to stash as arguments.
A: Just to be clear, starting Git 2.15/2.16 (Q1 2018), git stash save has been deprecated in favour of git stash push (though git stash save is still available for the time being).
See commit c0c0c82, commit fd2ebf1, commit db37745 (22 Oct 2017) by Thomas Gummerer (tgummerer).
(Merged by Junio C Hamano -- gitster -- in commit 40f1293, 06 Nov 2017)
stash: mark "git stash save" deprecated in the man page
'git stash push' fixes a historical wart in the interface of 'git stash save'.
As 'git stash push' has all functionality of 'git stash save', with a nicer, more consistent user interface deprecate 'git stash save'.
stash: remove now superfluos help for "stash push"
With the 'git stash save' interface, it was easily possible for users to
try to add a message which would start with "-", which 'git stash save'
would interpret as a command line argument, and fail.
For this case we added some extra help on how to create a stash with a message starting with "-".
For 'stash push', messages are passed with the -m flag, avoiding this potential pitfall.
Now only pathspecs starting with "-" would have to be distinguished from command line parameters by using "-- --<pathspec>".
This is fairly common in the git command line interface, and we don't try to guess what the users wanted in the other cases.
Because this way of passing pathspecs is quite common in other git commands, and we don't provide any extra help there, do the same in the error message for 'git stash push'.
With Git 2.18 (Q2 2018), the command line completion (in contrib/) has been taught that "git stash save" has been deprecated ("git stash push" is the preferred spelling in the new world) and does not offer it as a possible
completion candidate when "git stash push" can be.
See commit df70b19, commit 0eb5a4f (19 Apr 2018) by Thomas Gummerer (tgummerer).
(Merged by Junio C Hamano -- gitster -- in commit 79d92b1, 08 May 2018)
completion: make stash -p and alias for stash push -p
We define 'git stash -p' as an alias for 'git stash push -p' in the
manpage. Do the same in the completion script, so all options that
can be given to 'git stash push' are being completed when the user is
using 'git stash -p --<tab>'.
Currently the only additional option the user will get is '--message', but there may be more in the future.
The command line completion script (in contrib/) tried to complete "git stash -p" as if it were "git stash push -p", but it was too aggressive and also affected "git stash show -p", which has been corrected With Git 2.28 (Q3 2020).
See commit fffd0cf (21 May 2020) by Ville Skyttä (scop).
(Merged by Junio C Hamano -- gitster -- in commit a8ecd01, 09 Jun 2020)
completion: don't override given stash subcommand with -p
Signed-off-by: Ville Skyttä
df70b190 ("completion: make stash -p and alias for stash push -p", 2018-04-20, Git v2.18.0-rc0 -- merge listed in batch #5) wanted to make sure "git stash -p <TAB>" offers the same completion as "git stash push -p <TAB>", but it did so by forcing the $subcommand to be "push" whenever then "-p" option is found on the command line.
This harms any subcommand that can take the "-p" option --- even when the subcommand is explicitly given, e.g. "git stash show -p", the code added by the change would overwrite the $subcommand the user gave us.
Fix it by making sure that the defaulting to "push" happens only when there is no $subcommand given yet.
A: The push command is intended to always be used over the save command, as it is more flexible and uses more conventional command line arguments. The save command is deprecated for these reasons.
Replacement
The push option was introduced in 2.13.0 in order to provide the command line arguments in a more conventional way than save does.
The rationale for this change was documented in the commit messages which added the command to Git:
f5727e2:
Introduce a new git stash push verb in addition to git stash save. The
push verb is used to transition from the current command line arguments
to a more conventional way, in which the message is given as an argument
to the -m option.
This allows us to have pathspecs at the end of the command line
arguments like other Git commands do, so that the user can say which
subset of paths to stash (and leave others behind).
c0c0c82:
With the 'git stash save' interface, it was easily possible for users to
try to add a message which would start with "-", which 'git stash save'
would interpret as a command line argument, and fail. […]
For 'stash push', messages are passed with the -m flag, avoiding this
potential pitfall. Now only pathspecs starting with "-" would have to
be distinguished from command line parameters by using
"-- --<pathspec>". This is fairly common in the git command line
interface, and we don't try to guess what the users wanted in the other
cases.
fd2ebf1:
'git stash push' has all functionality of 'git stash save',
with a nicer, more consistent user interface
Deprecation
The save command was officially deprecated in the 2.16.0 release of Git:
"git stash save" has been deprecated in favour of "git stash push".
The deprecation of save is explained in its documentation:
save [-p|--patch] [-S|--staged] [-k|--[no-]keep-index] [-u|--include-untracked] [-a|--all] [-q|--quiet] [<message>]
This option is deprecated in favour of git stash push. It differs from "stash push" in that it cannot take pathspec. Instead, all non-option arguments are concatenated to form the stash message.
Short form
In addition to the standard form of the command, push has a short form whereby "push" is omitted from the stash command. The save command has no such equivalent. Per the documentation:
For quickly making a snapshot, you can omit "push". In this mode, non-option arguments are not allowed to prevent a misspelled subcommand from making an unwanted stash entry. The two exceptions to this are stash -p which acts as alias for stash push -p and pathspec elements, which are allowed after a double hyphen -- for disambiguation.
git stash
git stash -p
Command comparison
From reading through the documentation, I think this should be a fairly complete comparison of the two commands:
push
save
git stash push
git stash save
git stash push -m <message>
git stash save <message> or git stash save -m <message>
git stash push -m <message> (message starting with "-")
git stash save -m <message>
git stash push [--] <pathspec>…
N/A (not possible)
git stash push --pathspec-from-file=<file>
N/A (not possible)
git stash
git stash save
git stash -p
git stash save -p
git stash -- <pathspec>…
N/A (not possible)
As shown in this comparison, the notable changes between save and push are:
*
*A partial stash can be created using pathspecs using push, but not save. The pathspec can be provided either as inline arguments or by using --.
*The message can be provided as an inline argument with save, but must be provided by -m in push

Q: How to import font-awesome in node.js to use in react.js? I am working with node.js and react.js.
I already imported my own css file like so:
import React from 'react';
import Modal from 'react-modal';
import './../App.css';
this works fine, but when I try to add font-awesome like so:
import './src/font-awesome-4.7.0/css/font-awesome.css'
then it doesn't work.
Am I doing something wrong? Or is there maybe another way?
A: Here's how i did it entirely in the front end react side:
*
*Include font awesome inside the <head> tag
<link rel="stylesheet" href="https://maxcdn.bootstrapcdn.com/font-awesome/4.7.0/css/font-awesome.min.css">
*Install react-fontawesome
npm install --save react-fontawesome
*Import the file and use it in your react components
import FontAwesome from 'react-fontawesome';
// ..rest of your code

Q: Pandas skipping lines (stop warnings from showing) I am reading a CSV file in Python this way using Pandas:
data = pd.read_csv('file1.csv', error_bad_lines=False)
I am getting:
Skipping line 6: expected 4 fields, saw 6
How do I stop this warnings from showing up?
A: From the docs:
warn_bad_lines : boolean, default True
If error_bad_lines is False, and warn_bad_lines is True, a warning for
each “bad line” will be output.
So set warn_bad_lines=False
data = pd.read_csv('file1.csv', error_bad_lines=False, warn_bad_lines=False)

Q: Cannot find module 'react/lib/ReactComponentTreeHook' from 'ReactDebugTool.js' I'm trying to get Jest to run a snapshot test of my React app. The versions from my package.json:
"react": "15.6.1",
"react-dom": "15.6.1",
"react-test-renderer": "15.6.1",
I can't get past this error:
● Test suite failed to run

at Resolver.resolveModule (node_modules/jest-resolve/build/index.js:179:17)
at Object.<anonymous> (node_modules/react-test-renderer/lib/ReactDebugTool.js:16:30)
I have tried removing and reinstalling my node_modules dir and I've verified that the path to my component is correct but still get this same error.
My test looks like this:
import React from 'react';
import renderer from 'react-test-renderer';
import { Section } from '../../app/views/containers/section';
it('renders correctly', () => {
const section = renderer.create(
<Section key="1" section="finance"/>
).toJSON();
expect(section).toMatchSnapshot();
});
What am I doing wrong?
A: On 0.47.0
Still had errors with the accepted answer had to do the following:
"react-dom": "^16.0.0-beta.5",
"react-test-renderer": "16.0.0-alpha.12",
enzyme will work with the above changes but any sort of simulation will not, disabled taps until they support.

A: While upgrading to React 16.0.0, I did notice that you do need to upgrade react-dom to 16.0.0 and it works flawless!
A: Ran into the similar problem last week, we have a React-Native project that has recently upgraded to:
"react-native": "0.45.1"
"react": "16.0.0-alpha.12"
"jest": "20.0.4"
"react-test-renderer": "15.5.4"
and then we try to run our Jest tests and we saw the same issue as you mentioned above. Then we realized there is a cutting edge version of the
react-test-renderer and we tried that one out:
"react-test-renderer": "^16.0.0-alpha.12",
And now the issue is no longer there.
A: The package named "storyshots" (link to the old package for reference) is deprecated and replaced by "@storybook/addon-storyshots" at the time of writing (2022), see official documentation

Q: IntelliJ IDEA debugger is too slow to start on macOS IntelliJ IDEA debugger is too slow on my new MacBook Pro 13 inch TouchBar model (late 2016). It has an i5 2.9ghz (6th Gen) and 8 GB ram.
Is there something wrong with processing power or is something else wrong? On my pc (i5 4670k, 8gb) the same version runs fine.
A: Agree with CrazyCoder. There is an easier way for obtaining/modifying hostname instead of using the github repo.
*
*In system preference, click sharing
2. Click edit in the popup window. In my case, the hostname is MacBook.local.
3. sudo vi /etc/hosts

A: You may have a problem with DNS, see the following answer:
git clone https://github.com/thoeni/inetTester
java -jar ./bin/inetTester.jar
Find the hostname that's output from the .jar.
sudo nano /etc/hosts and add these two entries.
127.0.0.1 <output-host-name>.local
::1 <output-host-name>.local
A: I would like to add one more case. If we have a number of method breakpoints, then the Intellij will run extremely slow.

Q: Obtain root directory of multi-module maven project from a Mojo I'm developing a maven plugin, and I need to obtain the root directory of multi-module project.
With mavenProject.getBuild().getDirectory() I can get the path to directory of current module, alright.
So thought I'd try to get root MavenProject, but with getRootProject() defined as below, getRootProject().getBuild().getDirectory() returns "${project.basedir}" (literally that String value... which I don't know how to resolve, and even if I did resolve it it would resolve to current module, which is not what I want).
@Parameter(defaultValue = "${project}", readonly = true)
private MavenProject mavenProject;
// ...
private MavenProject getRootProject() {
MavenProject project = mavenProject;
while (project.getParent() != null) {
project = project.getParent();
}
return project;
}
How do I get (resolved & absolute) path to root module?
A: Thanks to this answer which deals with the same issue from a different perspective (not from a Mojo), I found a solution:
Add the following field to my Mojo:
@Parameter(defaultValue = "${session}", readonly = true)
private MavenSession mavenSession;
Then use it this way:
mavenSession.getExecutionRootDirectory()

Q: Set offset or initial position for a cell in a collection view I want to add some space before the first cell in a collection view, something like an offset, my collection view has a horizontal scroll position.
Here is my current collection view:
It has a leading constraint of 35, what I want is the cell to start at an "x" position of 35 but with the ability to scroll full width like in this:
Is there a way to create that initial offset in a collection view using Swift 3?
A: Swift 5 / Xcode 11
Thanks Alexander Spirichev.
Based on his answer, you can also set the left inset to 35 points programmatically:
let layout = UICollectionViewFlowLayout()
layout.scrollDirection = .horizontal
layout.minimumLineSpacing = 8
layout.sectionInset = UIEdgeInsets(top: 0, left: 35, bottom: 0, right: 0)
collectionView.setCollectionViewLayout(layout, animated: false)

collectionView.setCollectionViewLayout(layout, animated: false)
A: You could just set Section Insets for Collection View Flow Layout without code.
A: You need to set contentInset
- (UIEdgeInsets)collectionView:(UICollectionView *)collectionView layout:(UICollectionViewLayout*)collectionViewLayout insetForSectionAtIndex:(NSInteger)section{
return UIEdgeInsetsMake(top, left, bottom, right);
}
you can see in detail here
A: You can set space before the initial cell in collectionView(_ collectionView: UICollectionView, cellForItemAt indexPath: IndexPath) as follow:
if (indexPath.row == 0 || indexPath.row == 1) {
// Set value according to user requirements
cell.frame.origin.y = 10
}
A: A bit late to the party here, but I came across a couple solutions
The right way (scroll to first cell):
https://coderwall.com/p/e-ajeq/uicollectionview-set-initial-contentoffset
Simple hacky way:
I add in a transparent "spacer" cell to the first item to offset the rest of the cells.
func collectionView(_ collectionView: UICollectionView, cellForItemAt indexPath: IndexPath) -> UICollectionViewCell {
let cell = collectionView.dequeueReusableCell(withReuseIdentifier: "collectionCell", for: indexPath)
if (indexPath.row == 0) {
cell.backgroundColor = UIColor.white
return cell
}
cell.backgroundColor = UIColor.green
return cell
}
func collectionView(_ collectionView: UICollectionView, layout collectionViewLayout: UICollectionViewLayout, sizeForItemAt indexPath: IndexPath) -> CGSize {
if (indexPath.row == 0){
//spacer
return CGSize(width:6, height:50)
}
return CGSize(width: 50, height: 50)
}
A: If you only want the cells in that section to have the padding, then use sectionInset from UICollectionViewFlowLayout as suggested in the other answers.
But from what I can guess you're probably fine with instead setting contentInsets on the collection view itself (inherited from UIScrollView)

Q: Preventing new line in textarea I'm working on a chat feature (using Vue) and am using a textarea for my input so the overflow wraps and is more readable for users writing longer messages. Unfortunately, when the user keys down enter and submits, the cursor moves to a new line before submitting, making the UX feel off. Any ideas for how I could disable the newline on submit using vanilla Javascript? As you can see, I've tried adding a replace() function but to no avail.
My textarea:
<textarea id="btn-input" type="text" class="input-group_input" rows="4"
placeholder="Type your message here..." v-model="body"
@keydown.enter="postReply()">
</textarea>
My submit method:
postReply() {
this.$http.post('/api/chat/' + this.session.id + '/replies', {
body: this.body
}).then((response) => {
this.body.replace(/(\r\n|\n|\r)/gm,'');
this.body = '';
this.replies.unshift(response.data);
}).catch((error) => {
})
},
A: Use @keydown.enter.prevent="postReply". This will prevent the default action of the enter key, which is to created a newline, but still call your method.

Q: Coalescing aggregate of fields in postgres I'm trying to group by a name field, but with a 'coalescing aggregate' of the other values a row might have. Here's the data:
