Ask HN: Email client alternative to Nylas N1? - sreenadh
I am currently using Nylas N1 and I did see some alternatives last month. I decided to try them after I was done trying out N1. Well, now I cannot find the links and I think my browser messed with my bookmarks ;). So, kindly list the alternatives any of you are aware of. I did check all the links on http://alternativeto.net/software/n1/, but no good.
======

If you have feedback about N1, I'd love to hear it! :) You can post here or
always email me directly. (I'm the founder/CEO.)

Hi! I'm looking for alternatives too, mainly for two issues:
1) I can't insert inline images 2) My emails are not being marked as read in
server, so it's a mess when I go to my iPhone...
~~~
MagisDing
Try Canary Mail [http://canarymail.io/](http://canarymail.io/), snappy and
beautiful. And its slack channel is quite robust (not like Nylas, please
forgive me) although there only two people in its development team.

How do you think we could improve the Slack room? We currently have 2253
people there, so it's usually quite busy. It's free to join here:
[http://slack-invite.nylas.com/](http://slack-invite.nylas.com/)
(The mark-as-read issue has been fixed and we're working on shipping support
for sending with inline images. Gmail didn't have this for about the first 6
years.)

Reading through the claims, the requirements for a "beacon" suggest that this
_doesn't_ read on geolocation by IP address. I'm not sure about geolocation by
triangulation from towers that don't specifically transmit information
intended to identify a location.

C64 Keyboard Prototype - erickhill
http://www.breadbox64.com/blog/c64-keyboard-prototype/
======
vardump
Keyboard is pretty amazing for C64 preservation efforts. Perhaps lessons
learned could be applied to other same era systems.
There's one part in C64 that's becoming more and more rare — the amazing SID
sound chip.
I wonder whether it'd be possible to have production runs of truly new 6581
and/or 8580 SID chips. Does someone still have the old masks?
Other chips you could emulate with an FPGA. But SID is partially analog, so
it's special. Some say no two SIDs sound the same.
Btw, recent C64 music demo playing off 1 MB Ocean style (= ROM) cartridge (not
REU):
[https://www.youtube.com/watch?v=7qxxnJVU4jQ](https://www.youtube.com/watch?v=7qxxnJVU4jQ)
[https://www.youtube.com/watch?v=UYAf_awh5XA](https://www.youtube.com/watch?v=UYAf_awh5XA)
Yes, it's real. Not particularly good example of SID though, but still
impressive for 1982/83 technology.
But this one does show off SID; C64 "Cubase", realtime DSP (timestretch,
low/high pass filter, distortion, etc.) pretty amazing:

> Does someone still have the old masks?
You can probably reverse the masks with a microscope with a little elbow
grease. Not trivial by any means, but doable by someone in a garage as a
hobby.
The real question, does a fab that can work with that process still exist?

There’s an ongoing effort to understand the SID here

Those acrylic backing plates are going to crack at some point. The author

Quitting Chrome: Because Google+ - badloginagain
This weekend I made a fairly major change to how I interact with the web- I consciously switched default browsers. Fed up with Google's constant ramming of G+ down my throat, I've decided to hit 'em where it hurts: their marketshare. So I've switched to Firefox, and while noticeably slower, I feel it's a browser I can put more trust into.<p>Google should be employing a strategy of invisible control over how people interact, not forcing a centralized interaction layer on something that is inherently decentralized. They should be quietly creating and controlling channels of communication that I cannot live without. Apply the strategy that grew their search engine to all Google initiatives.<p>Or I will find alternatives.
======
xpose2000
This sounds backwards to me. If anything, you should be quitting Google, the
search engine, rather than their browser. Google can live without you being a
Chrome user, but it hurts them if you switch to Bing or duckduckgo.

lelandbatey
Yes, but switching to Firefox also hurts _me_ a lot less than switching to
Duck Duck Go.

Agreed. I have been using DDG for ~two years. Maybe once or twice a week, I
actually ask DDG to search in google (with awesome "!g" or "!img" bang-
commands). DDG works consistently great, and the new DDG is even better, with
auto-completion, images and video tabs. And I'm using Firefox as well.

Using Google doesn't require an account of any kind, and a Google+ account is
only required for social features such as posting comments or sharing links.
The launch state of Google+ provided an extremely hostile experience due to
policies such as "one social identity per account" and "use a government-
approved non-ethnic name", but these issues were resolved years ago with the
Pages feature.

I dont understand when people find firefox noticeably slower. I wonder if
thats related to OSX.
Regardless, I agree with the move 100%. Thanksfully, while Firefox may not be
the best, its very good/useable for everything.
If ever it isnt good enough anymore and there is no other replacement - this
is when we'll really be cornered
~~~
subsection1h
> _I dont understand when people find firefox noticeably slower._
In my experience, people who think Chrome is faster than Firefox never have
hundreds of tabs open.
I like Chrome and I use it for development, but I use Firefox for general web
browsing because it handles hundreds of tabs much, much better. Not only is
Firefox's performance better, but Firefox extensions such Tree Style Tab and
Session Manager are vastly superior to the tab management extensions that are
available for Chrome. For example, I'm still waiting for a Chrome extension
that supports the basic task of appending the current window to a previously
saved session.
~~~
frik
Browsers that use several child processes (like IE, Chrome, Safari/WebKit2)
are faster, have less latency, crashes involve only one tab and the child
processes run with limited OS priviledges ("sandbox") than browsers with only
one process (Firefox, Safari/WebKit1).
Mozilla is working on a multi-process Firefox, one can activate it with a
hidden flag (it is still not production ready, and it will break several old
plugins).
With multi-process browsers one can have hundreds of tabs open for weeks (if
you have enough RAM like 8+ GB).

It's more complicated than that. For one thing, "have less latency" is often
the opposite: a keypress in a multiprocess browser has to travel from the
user-facing process to the child process, then the effects have to travel
back. In a single-process browser, there is no need to cross that boundary
back and forth. You can see this in action in games for example, where you can
sometimes see more input lag in multiprocess browsers.
Regarding speed, depends how you define it. Definitely multiprocess gives you
responsiveness - one slow tab doesn't slow down the others. But throughput,
not necessarily.
Overall though, multiprocess is a good thing. I'm just saying it isn't a win
across the board, like everything it has downsides.

adamconroy
I've done the same.
I use gmail a lot, I have an Android phone and I was using desktop Chrome for
years. However I started to notice things that worried me, for example I would
be using Chrome on my PC but definitely not logged into Gmail / Google+, then
I would see that my recent google searches from the desktop Chrome would
appear in my recent searches list on Android within seconds. I could somewhat
accept that if I was logged in to Google, but I don't accept that if I am
logged out.
On one hand the functionality is pretty impressive, on the other hand my gut
feeling is they have gone too far.

I don't understand why Chromium isn't a more popular alternative to Google
Chrome. It's the open-source basis of Google Chrome. It runs noticeably faster
than Firefox, while being similarly trustworthy. It's a great browser,
available on all conventional operating systems. What's not to like?
~~~
jmillikin
Chromium doesn't have stable builds, and the official snapshot binaries don't
auto-update. This isn't so bad if you're using an OS with a package manager
such as Debian, but it makes Chromium completely impractical for Windows and
MacOS users.
------
mikeratcliffe
Firefox is faster these days. If you find it slower then you probably have
addons that are slowing things down.
Try disabling your addons and enable them one by one to find the culprit.

I switched from Chrome as my default browser after two years of using it just
two months back. Sometimes Firefox isn't able to render certain websites and
rather spits out the html, but aside from that, I haven't had any issues. I
think it works noticeably faster for me. I use it on both OS X and Windows,
and it works great on both. It is also a lot more customizable and lets me run
my own sync servers.
~~~
adrusi
I find the problem you mention very odd. I've used Firefox for over a year and
have never seen anything like that. Is it possible that you have some
configuration messing it up? Otherwise all I can think of is that the sites
are sending html content with the Content-Type header of "text/plain" and
Chrome is deciding to render it as html based on other clues (which would be
non-standard behavior).

Show HN: Freebie finding site using interesting algorithm - tectonic
A little while ago I built an automated website that finds free stuff while filtering out scams. It works in an interesting way. Most freebie sites on the web contain a mix of real, useful free stuff and scammy affiliate and pyramid schemes. I realized that affiliate links are always unique (because they need to contain an affiliate code) while real freebies have URLs that co-occur across multiple sites at roughly the same time. I wrote a crawler in Perl and MySQL that looks for repeating, off-domain URLs that temporally cluster on multiple free stuff sites. I was surprised and pleased to find that this trick eliminates affiliate links with almost 100% success and tends to find real freebies. I then let users rate freebies and provide category and description information.<p>Here's the result: http://absurdlycool.com<p>Do you folks have suggestions about how I could make the site more useful? I recently worked on a redesign, but I'm a programmer, not a graphic designer :)

detection of my home WiFi network (other than turning off WiFi of course)

When you lose the home Wifi signal, do the 'going out' actions (including turn
off Wifi). When GPS tells you you're back home, do the 'coming in' actions

I can guarantee it will go for more than $500. If not to me for what I bid,
then it will go even higher than what I bid... which is a secret. So no one
bid $502, okay.

My prediction: $50K to $100K
I hope I am right. It's a good cause.
Here's an idea: PG, how about offering a lunch meeting to the HN member who
makes the closest prediction to the winning bid? They would have to post it on
HN and FB or something like that. This serves the purpose of helping advertise
this worthy cause.

Show HN: My dogfooded Bookmarking Site / rss-crawler / ... - NicoJuicy

======
justboxing
Nice work! Looks like HN / Reddit in terms of functionality and layout.
Really impressed that you've built all the features like RSS crawler,
taxonomy, user and role management etc.
------
NicoJuicy
Side note:
I have been low-level dogfeeding this for a couple of years for personal use (
it was a MVP for a company). It's actually quite usefull.
Things i have included:
\- RSS crawler ( depending on the user that submitted it. Eg. TaglyBot is
mostly the one i used for adding RSS-Feeds)
\- Tag Synonyms/Hierarchy/Administration ( that's why i used the A.I. tag)
\- Comments
\- User Management / Role Management
\- Popular /Upvoted tags
\- You can drag tags to the top, to bookmark them for personal use ( if
loggedin)
\- Url modifiers through prefixes or affixes on the url ( Reason:
circomventing paywalls by using the facebook sharer as a prefix, ... -
Companies mostly use this kind of trick for Social Media)
\- Custom js elements depending on a certain tag ( eg. you can add HTML
through using the HTML tag) - yeah, enjoy screwing me :p
\- Those custom JS elements are generated server using the V8 engine ( for SEO
purpose)
\- generic button / link behaviour ( eg. there's a button to "Post to HN" ). I
posted too much on HN for a while as i found it easier to "Bookmark it to
HandlR", add the tags and then press "Post To HN"
\- There's a private mode that only lists your own votes and submitted items (
not sql optimized though, very slow for now)
\- There's a bookmarklet, so you can drag a URL to the bookmarklet. It will
redirect you to the handler site so you can submit it.
\- If you only add a link, it will fetch the <Title> of the remote site ( easy
for fast submitting)
\- Create alternative url's ( eg.
[http://brugge.sapico.me](http://brugge.sapico.me) for crawling the local
news/ activities related to where i live)
\- ...
It's just a side project, but i just improved the sql index for the many-to-
many relationship for Tags/Items and planned to do a Show HN for fun.
Tech related:
\- Plain old Asp.Net MVC with some jquery and mustache ( for the custom html
elements), a V8 engine as custom javascript view engine and a DDD-layered
application.
I mostly use IQueryable instead of Lists though, for ease of programming.
I ( before i submitted it here) also added a cache for 60 seconds ( hug of
death is expected) and a new post doesn't go to the Newest url now ( since it
would be confusing because of the caching).
PS. HN is amazingly simple though
PS 2. The company went for sharepoint a couple of years ago and very recently
they contacted me again :p

Ask HN: I built a referral program for developers, would love feedback - geekjock
Hi everyone,<p>Over the weekend I launched a referral program for my app Pull Reminders (<a href="https://pullreminders.com" rel="nofollow">https://pullreminders.com</a>). Here's a quick summary with two screenshots showing what it looks like: <a href="https://twitter.com/abi/status/1001432164569960451" rel="nofollow">https://twitter.com/abi/status/1001432164569960451</a><p>For some background, Pull Reminders is used by over a thousand developers and has 100+ new developers signing up each week. I've been looking at strategies to reach more potential customers without having to spend money or a ton of time so a referral program seemed like it had potential.<p>There are well-known success stories out there of referral programs designed by consumer products like DropBox, but far fewer for B2B, and almost none that I found which were targeted at developers (DigitalOcean is one).<p>I considered a cash incentive (ie. $25 per converted referral), but developers are well-paid so offering cash seemed like it could actually be a turn off. I considered offering credits, but Pull Reminders is expensed by teams so for an individual on the team this feels like a poor incentive. This eventually led me to the idea of offering free coffee (and tea)–not just regular coffee, but high-end coffee from specialty roasters. It's a generalization but I feel that most developers like coffee, and getting a bag of specialty coffee seems like it could be a fun and novel reward.<p>I have no idea if my approach or design is good so I would love your thoughts and feedback. How can I improve the structure, presentation, or description of my referral program? Is the coffee idea good? Is my copy written well (this was tough – I spent several hours repeatedly tweaking and rewriting)?<p>P.S. Sorry for the long post – I plan on eventually turning my learnings and results into a blog post.
======
tixocloud
Hi there,
Based on your post, I reckon your overarching goal is to acquire more
customers and the tactic you're focused on is a referral program.
But perhaps it might be good to take a step back. Firstly, do you know what
the value of your customers are at the moment and how much will you be willing
to spend per customer?
Referral programs could be a good strategy provided you feel that your
customer also has a potential network to reach out to and you have enough to
incentivize them, which leads back to how much you're willing to spend per
customer.
That being said, have you tested the coffee idea out with your existing
customers? More importantly, have you had a chat with your existing customers
to understand what would get them to refer you to their networks?
The way I'd approach it is to talk to your customers and test out your
strategies (i.e. coffee or otherwise).
Happy to discuss further as I've been involved with designing
loyalty/rewards/switching programs.
------
inputcoffee
It is certainly an interesting problem. I don't know that I have the solution.
I agree with everything you said about the problem around finding a good
reward.
However, coffee drinkers can be picky. It would not motivate me, but then
again I am not sure what would other than the benefit of doing my friend and
the customer a favor.
~~~
geekjock
Thanks for the feedback!
------
jbardnz
Looks really great. As a developer I would be way more motivated by this than
some free credits for my companies account.
How do you handle fulfillment? Seems like it could be a real time suck if it
is manual? Also do you ship internationally?
~~~
geekjock
Thanks for the feedback! Fulfillment - I plan on just manually ordering coffee
to people once per week. If it gets to be too much work that'd be a great
problem to have :)
I do ship internationally, and if for some reason I can't I would send a gift
card instead.
------
saluki
How about an amazon e-gift card based on your plans they get the referral on.
Maybe a minimum of $20, then $50 and $100.
How about a bonus e-gift card every 12 months their signup is a customer.
So if they refer a signup on your $99 plan they get $100 after it is confirmed
and then every 12 months another $100 e-gift card.
I don't drink coffee btw, but I do have an amazon wish list.
~~~
geekjock
I've decided to switch to amazon gift cards!

trcollinson
I don’t drink coffee but I know a ton of people who do. I actually really like

also not supposed to even ask about other mathematician's compartments, right?

Ask HN/PG: Leaderboard acting strange? - johns

======
pg
I just restarted the server. Users are lazily loaded, so the leaderboard will
look odd for a brief period after a restart.
~~~
ivankirigin
The 'submitted' link on the profile basically doesn't work
<http://news.ycombinator.com/submitted?id=pg>
<http://news.ycombinator.com/submitted?id=ivankirigin>
I suppose it is related to the lazy loading?
~~~
pg
Yes, items are lazily loaded too. Responses to http requests get killed after
30 sec, so if the server has to load too much stuff to satisfy a request, it
will die first.
It's always been this way. After the server has been running for a bit it
stops being a problem.
~~~
ivankirigin
Perhaps you should hide features that are likely going to be unavailable if
the server recently restarted.
No need to send users down a rabbit hole, and certainly no need to waste the
cycles on your machine.

frequently from my own profile as an easy way to check up on conversations on

Why I have migrated from Ruby on Rails to Seaside - duck

DanielRibeiro
One of the things that troubles me is that even Seaside's creator (Avi Bryant,
who sold his company to twitter recently) mentioned how this way of doing web
apps is old:
[http://python.mirocommunity.org/video/1186/djangocon-2009-dj...](http://python.mirocommunity.org/video/1186/djangocon-2009-django-

He went overboard and implemented smalltalk in javascript (named clamato):

~~~
jcromartie
That's a great talk, thanks for sharing. It seems like clean separation
between a JavaScript client app and a server-side data/controller layer is the
way forward.
But I'll still content that web development as a whole is broken, because web
dev is a teetering mile-high tower of abstractions and when something leaks,
it tends to trickle all the way down and stink up the whole stack.
------

rbranson
Quite interesting. It does seems most of the advantages of Seaside are from
using the Smalltalk environment. One thing is definitely clear: Ruby needs
much stronger debugging support.
~~~
barmstrong
I use NetBeans to code Ruby and the debugging is great. You can set
breakpoints, step through, set watch variables etc.
I don't have a ton of experience debugging with other languages (prob Java is
the only other one), but what is Ruby missing?
~~~
avibryant
Here's the experience of debugging in Seaside:
1\. You reload a buggy app in the browser.
2\. Oh noes, you hit an error: the browser shows you the stack trace.
3\. At the top of the stack trace, there's a "debug" link: if you click that,
the HTTP request causes your dev environment to pop up a debugger. No response
comes back to the browser yet.
4\. In the debugger, it's as if you had a breakpoint right before the error
occurred: you can walk back through the stack and inspect the state of each
frame, etc.
5\. If you see the problem, you can edit the code - right in the debugger UI -
and hit save. The stack will unwind to whatever frame you are editing the code
in, and restart from the top of that method or block.
6\. As execution continues, the HTTP response finally goes out, and you see
the (newly fixed) web page come into the browser.
As someone noted in another comment: although I was the main developer and
evangelist of Seaside for a while, I no longer use it or contribute to it
(though many others have taken up the torch) but I can't tell you how much I
miss this workflow.
(Edited for formatting)
~~~
cpenner461
From a quick glance this sounds similar to the debugging provided by
paste/pylons? I've only played briefly with pylons so I may be way off
though...
------
mark_l_watson
Although I use Lisp+Ruby+Java for just about everything I do, I do keep an eye
on Squeak and Pharo (hoping for JIT performance someday getting fast like the
commercial VisualWorks product).
I periodically run through a Seaside tutorial - really neat stuff, and very
easy to deploy on Linux servers (I blogged about how to do this several years
ago).
One thing that attracts me to Seaside is that (unfortunately) most of the web
apps I write are low volume sites so I would not have to worry too much about
scaling. I make this same argument for using Rails rather than Java.
~~~
aaronblohowiak
"I make this same argument for using Rails rather than Java." -- JRuby is
pretty cool, no need to choose! It isn't as fast as raw java, but you can
easily swap out the hot paths with java to get additional performance.
~~~
stcredzero
Or, you could pony up for VisualWorks server licences and get even better
performance. (And swap out the hot paths with DLLs implemented in C.)
------
chc
Conceptually, I like Seaside. But I simply can't get past the hideous
abstraction-leaking URL scheme it insists on. They aren't resource locators;
they're session IDs, with all the info stored in the session state. Users
should be able to copy and paste URLs to things. They expect it, and that's
not an unreasonable expectation.
~~~
avibryant
Absolutely true for some apps (and for those apps, in Seaside as in any other
framework you can do the extra work to get bookmarkable URLs). For other apps,
it's nice not to have to worry about this. For example, when did you last
email someone a URL from your Gmail session?
~~~
silentbicycle
That's an excellent example. I've been a bit skeptical about continuation-
based web services, but that makes a lot of sense.
------
nek4life
Interesting but I was constantly distracted by the X bullet points next to the
list items that you liked. Perhaps you could add a class to put checkmark
icons instead when writing an article like this.
------
jcromartie
I'm pitching Seaside as a contender for the platform to build a new app on
tomorrow. I'm completely and utterly sold on it. The experience is really just
unparalleled in the world of software and web development, and I think the
Smalltalk tools it is built on is a huge part of that.
------
kuahyeow
I'm intrigued by Monticello. Is that a source control tool ? Or is it far more
than that. The author seems to alude to Monticello as part of the smalltalk
package.
~~~
cwp
Yes, it's a source control tool. Smalltalk doesn't store source code in text
files, so you can't really use tools like git or svn to version Smalltalk.
Monticello is a DVCS written specifically for versioning Smalltalk code.
------
stcredzero
Is there a current hotbed of Squeak/Pharo/Seaside development? I'm wondering
where I should move in the US?
~~~
mattrepl
There's been an active Smalltalk community in Vancouver, BC. If you want to
stay in the U.S., then Seattle or Portland may work.
------
ghotli
Seaside seems interesting but how is the smalltalk library support? Does it
have a robust way to call libraries in other languages?
~~~
jcromartie
It has FFI, so you can call other libs as long as they are C-compatible.

I agree with near everything in the article, but think even interstitial ads
prove disruptive in a way that I can't get behind. I don't begrudge a game
provider for the use of ads, but think that unobtrusive banner space to be the
most acceptable. Oddly I feel like it goes a long way when ad providers use
language like "thank our sponsors" and have some self-awareness; it's easy to
tell when they've been suckered in by an ad provider to use all their most
annoying API's. Integration of ads that reward you for either clicking or
looking at them are also an interesting idea.

A new model of school in Sweden - Misha_B
http://www.economist.com/node/11535645
======
gahahaha
The experiences that were made from privatizing Swedish schools were:
* generally worse results and increased inequality
* 5 companies dominate the market, and makes huge profits
* Sweden has fallen from 3rd to 19th on the PISA test in reading.
* huge quality differences between schools
* schools have become a "sorting machine" where motivated parents and pupils choose certain schools and avoid other schools.
* The experience from Sweden, and research from OECD shows that more competition in school does not produce better results.

I actually went to Kunskapsskolan as the equivalent of a High School student.
Graduated in 2005. It work out very well for me, the freedom to go about the
curriculum at my own pace suited me perfectly. The experience of going there
was very much like what you would find at a university. The school demanded a
very high level of motivation and discipline. And this makes it problematic,
since quite a lot of students at that age were ill prepared to face that.
I might be hesitant to say that this reform has worked out well for Sweden as
a whole, as I think for-profit entities in charge of public education is a

Definitely the wrong direction, because it can go wrong on so many ways.
Myself I am a victim of for-profit education (well, my spouse is), effectively
locked in by contract at a company for 10+ years more. It sounds so good in
the beginning, but once you finish your studies and you stand in front of that
loong walk...

It's interesting that no mention was made of the Sweden's extremely poor
policies and record with respect to homeschooling. There has been a lot of
press the past few years over the Johansson family (child seized for being
homeschooled) to the Himmelstrand family (severe fines for homeschooling).
Here is a link to an HSLDA collection of other links that specifically address
homeschooling in Sweden (<http://www.hslda.org/hs/international/Sweden/>).

The school system in Sweden is many things (despicable, horrendous, etc etc),
but free market it is not. These private schools don't operate on a free
market - the government supplies the "customers" (students) under penalty of
prison* for the students' parents, for crying out loud.
* Or possibly even worse: a student who doesn't go to school is liable to end up in the clutches of the meddling welfare board.
~~~
olifante
I very much doubt that the Swedish school system can be seriously described as
despicable or horrendous, even if it has fallen from its former glory. Would
you care to elaborate?
~~~
Muzza
All mandatory school systems are despicable and horrendous. The first major
issue is the coercion involved: they control a child's life for 9 years (or
even 12 years in some countries). It's absurd. This alone should be reason
enough to dissolve the entire public school system (and possibly put various
Ministers of Eduction to trial).
The second major issue is that they are a tool the state uses to indoctrinate
children (naive by nature) with whatever the correct values of the day are.
Prussia (where public schooling originated) needed obedient soldiers, modern-
day Sweden needs a large underclass of socialists willing to support various
hare-brained political schemes. The schools reflect this. What happens, for
instance, if you call homosexuality "not normal"[1] in a Swedish school? It
gets you an F in biology and a label as a "homophobe" in the state-run
media[2]. One wonders what happened to students who questioned communism in
the Soviet Union.
See "Deschooling society" by Ivan Illich, "Underground history of the American
school system" by John Taylor Gatto.

Why was "goto fail;" added without any other change to that part of the code? - 0x006A

How could this ever happen? It does not look like a copy & paste error as suggested in other places,
it does not look like refactoring. Was it added intentionally to test something and commited by accident?
Is there any possible non malicious explanation someone could come up with?

matthewmacleod
Stop this nonsense. There are plainly dozens of reasons that this could have
happened accidentally. Literally every single developer has made similar
stupid mistake, and literally every organisation has released stupidly broken
code.
Yes, there should have been code review, static analysis, and testing in place
to prevent that. That'll probably start happening, and you can bet that there
will be serious discussions internally about what happened.
If this was the action of a malicious government agency, then it was horribly
hamfisted execution. It might offer plausible deniability in some sense, but
it's hard to imagine a situation where such an action would be worthwhile,
given the resources at the disposal of any such actor.
~~~
pessimizer
>it's hard to imagine a situation where such an action would be worthwhile,

This needs more defense. I find it hard to imagine a situation where such a
minimal and deniable action with such a massive effect _wouldn 't_ be
worthwhile.
~~~
tptacek
No, it doesn't need a defense. There is no evidence to back up the idea that
the bug was malicious. People that have worked on large C codebases have seen
crazier things than this. _Routinely_.
I understand that Rails developers believe that all the TLS stacks must have
dense rspec test coverage and zero-warnings static analysis passes in their
builds, but that isn't the reality for any TLS stack. These aren't Rails apps
(and, hate to break it to some of you, but your Rails test coverage isn't
doing as much for your security as you'd like to think it is).
This is a nutball conspiracy theory, another example of the tech "community"
eating its own rather than focusing on anything that would help mitigate
state-sponsored surveillance. And it's happening solely in the service of an
"exciting" narrative. The people promoting this bullshit conspiracy theory
are, by and large, doing it because they _want_ it to be true.

1\. It is certain that NSA has some very smart people playing with the sources
of the Apple crypto-modules.
2\. If you're a NSA boss, and some of your experts told you that you can break
SSL in Apple products with adding one line that could be almost certainly
attributed to inconspicuous human error, would you try to make a deal with
Apple?
3\. If you're an Apple boss, and NSA offers you cache (or other benefits, like
competitor intelligence) for adding plausibly deniable bug in your code, would
you turn it down?
There is no direct evidence for this case, sure. There is however ample
evidence in the Snowden docs that this scenario happens too often for this to
be called bullshit conspiracy theory.

Remember how Diaspora was supposed to be the private peer-to-peer encrypted
Facebook but peers private keys could be read or overwritten by anyone on the
Internet? Doesn't your argument suggest "Well we can't rule out the NSA having
a man on the inside trying to undermine their encryption"? Heck, why not go
all the way: the NSA funded Diaspora to bring Facebook to the negotiating
table?
Down this path lies madness. Software has bugs.

Yes, we can't rule that. But we could clearly see that the Diaspora codebase
screamed incompetence. Apple, on the other hand, has some very high quality
products and decades of experience.
Yes, it is quite possible that this is a simple bug. The other option is also
quite possible :)

It's not true that there was no other change in the code -- there was a change
eight lines earlier. It could be a mismerge of the latest upstream code. There
was refactoring nearby, and people can make stupid mistakes while refactoring.
I disagree that there's no "reasonable explanation", and so do most other
people who've looked at it. That doesn't mean it wasn't malicious, but it
means that it has reasonably plausible deniability. (Of course, if you _were_
being malicious, plausible deniability might be important to you.)
~~~
lyngvi
++ on mismerge. The change likely won't impact the output binary - compiler
should issue a warning, which devs might ignore; then the optimizer would
remove it as unreachable.
Perhaps the developer deliberately allowed that mismerge to give himself an
aura of incompetence/sloppiness, enhancing his plausible deniability when it
is discovered that one of his other changes led to an insidious vulnerability.
But more likely it was just an accident - if he were malicious, the effect of
bringing attention to his code would be highly undesirable.

It's not unreachable - it always executes if the if condition is false.

D'oh. That's what I get for not paying attention and looking at the
indentation instead of for braces. Still, my bet's on mismerge first - though
it'd be worth reviewing that committer's other changes.

If you are wondering whether there is a massive conspiracy to make software
weaker and to hijack the work of everyone writing networked software and
construct a massive surveillance apparatus and use it against enemies of
Freedom™ and randomly chosen accidental targets: the answer is _yes_. It has
been demonstrated beyond doubt.
If you're wondering whether this particular code is a consequence of all that:
probably not, but if it were it would prove anything that isn't already known.

A lot of code editors (Xcode doesn't by default, but you can easily configure
it to) have a keyboard shortcut for duplicating the current line. I have
plenty of times accidentally made changes at the wrong place in a file because
I was mistaken about where the cursor was.
The lesson is to always make sure to look at your diffs before you commit your
changes.
~~~

And to have someone else look at your diffs and sign off on them before it's
merged into master.
Google / Chrome does this, and so should everyone else, even more so if
they're dealing with security.
~~~
mistercow
That's a good measure too, although I think with a mistake like this, the
person writing the code might be more likely to spot the mistake than someone
else.
It also makes me wonder if the diff display shouldn't have a specific notation
for duplicated lines, since they are a special case that can easily be
mistaken for a trivial _change_ to a line with the way diffs are typically
shown.

Another person would say, they saw a little bigfoot standing on the river bank

to see a baby bigfoot." [1]
If someone said they saw a bigfoot shopping in Walmart, we could expect to
hear, "That's exactly the sort of a place a bigfoot would shop."
The conspiracy theorists and the honest mistake theorists are both finding

YouTube CEO on Facebook video ambitions: 'They should get back to baby pictures' - smacktoward

YouTube has been an incredible place for building an audience for me. I
started publishing videos in November of last year and growth has been
dramatic (for me at least— my content is pretty niche, I review website
builders): [http://s3.amazonaws.com/sitebuilderreport-

where I had to pay to access my audience. Lame.

She may be right.
Facebook has a lot of problems on its plate right now, but one of the worst
trends has been the poorly thought out march to video. It came from Zuckerberg
(1 and 2) and was repeated by senior FB executives, and then became a mantra
for publishers. Many made large investments in video programming for Facebook,
only to find the money isn't there and Facebook later decided to demote
publisher content (3 and 4).
This is not just large media companies that got burned, I know some smaller
producers who believed the "five years the feed will be all video" baloney and
shifted their efforts accordingly. Some were doing really important work, too,
around causes or local news. What a waste.
Meanwhile, it seems that overall video consumption in Facebook is declining,
and it's the one percent that get the most engagement, regardless of who the
publisher is (5).
I personally would not mind if Facebook turned back the clock 10 years, when
most conversations seemed to be personal and text-based, and the truckloads of
memes, ads, gaming achievements, real and fake news, and videos of cats
playing the piano had yet to be shoved down Facebook's maw and into our feeds.
Old-school text discussions seem to work for HN, why can't it work for
Facebook?

People don't really read in the same way as you might have previously
expected. ("Reading a short blurb or a tweet" is not the same thing.) Can't or
don't want to, I don't know, but they don't. You see the edges of it here, too
--tl;drs on HN posts, sometimes, that are less than a screenful of text. And
people think you're "spending a lot of effort" when you bang out a post about
as long as yours is--and, sometimes, try to frame it as a bad thing.
I tend to think Thomas Pettitt has a point[1].

Facebook isn't going away. However it seems to be coming apart because its
hard to argue that FB improves, rather than burdens, people's lives. Its
simply easier, less distracting and often happier connecting outside FB's
walled garden. For example:
Messenger --> rampant competition from about a dozen apps.
Community --> reported audience declines. From participation fatigue, privacy concerns, and competing sites.
Publishing --> push-back from content providers and publishers who don't wish to be assimilated into the 'borg'.
Payments --> no real competitive offering.
FederatedID/SSO --> rampant competition from Google, LinkedIN, Github, etc.
I really believe Facebook is grossly overvalued as an internet property, much
in the same way MySpace and AOL were in the 'old days'. I also suspect that
Twitter remains undervalued in terms of influence and - importantly - 2nd/3rd
order reach (eg. republishing).
There's something to be said for building products that make people's lives
easier and truly happier, and I'm not sure that FB does either anymore.

IMO that’s probably good for Google because it’s likely going to be a wasted
effort. Even if they built great stuff, I can’t see this being more successful
than something like Google+ or Facebook’s attempts at making an Android

terms of video, I think they may be able to do something similar to what
Snapchat has done, but that’s about it.

My 2c is that for mass consumption, streaming is where the puck is going, not
short-form videos. Kids are watching Minecraft streaming, they're not watching
punks like Logan Paul until they are in their teens, and my guess is as those
younger kids get older, tastes will change and Paul et al will be done. And
even when you think about teens, streamers like Dr Disrespect seem to capture
far more zeitgeist than YouTubers. Is Casey Neistat really a thing anymore?
IMHO Facebook really should be doubling-down on local sharing and improving
that experience, Google Photos is far and away the best photo product for me.
Replicating YouTube won't work, the quality of the platform and the network
effects are too strong. Whether Facebook can do something disruptive like
Twitch I don't know. Maybe IRL streaming of C-list celebrities like Snoop or
Kylie Jenner?

Youtube gets this right and puts the content first, on all endpoints. I see a
youtube video and click it, I get a video.
If I see a facebook link, there are many problems:
\- I don't know if it's a video
\- I don't know if I'll see a login page or if I'll get to the content
\- I don't know if the content is viewable by me because of privacy settings
And then this works the other way - why should I share a video on facebook
when I can't tell if my recipient will be able to see the video? I don't know
if they'll get a login prompt. I don't know if they have the permissions to
see the video.
All this friction doesn't exist with youtube, or at least is extremely
minimal.

Agreed. I'm always weary of clicking on a Facebook video because I don't want
a history of that going on my wall or some other kind of trail. I don't want

in comparison to the rest of the shit that comes with being in the Facebook

Instagram is Facebook's attempt to dethrone YT as the dominant player in the

getting a bit annoying, especially when you can't skip them. If a valid
challenger were to arise, I feel monetisation strategy is where this battle
will be lost or won. The least annoying/intrusive will win every time.

The early automobiles were a joke, so they called it like they saw it. You can
hardly blame people for not seeing where it would lead, often beyond their
professional lives. Take for contrast the reaction of French factory workers
when automated textile production started to come online, or cabbies when
automated fare metering hit.

pythonaut_16
Youtube seems to be one of the more egregious parts of the Google ecosystem.
Like sure Gmail has its problems, but ultimately it is an excellent web based
email system that's hard to beat because it's a great product.
Youtube's main strength seems to be primarily its first mover advantage, and
the fact that building a video hosting site is a rather costly venture.
Neither of those are a very defensive moat against competitors like Amazon and
Facebook

I do not think gmail is an excellent product. For me it's backed by a giant
that guarantees its availability and functionality almost anywhere in the
world (looking at you China). I would use something else in a blink of an eye.

Professional Software Engineer Exam coming in April 2013 - stephen
http://ncees.org/About_NCEES/News/News_Pages/New_PE_Software_exam.php
======
spamizbad
Looks like "How to do Waterfall" (62.5% of the test) with additional coverage
of Security (15%), QA (7.5%), and Engineering process (7.5%), and
Configuration Maintenance (7.5%). There are 80 multiple-choice questions
spread across 2 sessions (4 hours each). Open book.
An overview of the exam:
[http://ncees.org/Documents/Public/Exam%20specifications/PE%2...](http://ncees.org/Documents/Public/Exam%20specifications/PE%20Software%20Apr%202013.pdf)
Not something I'd feel inclined to get unless this somehow became an industry
requirement- which is unlikely - Agile and progressive Software Dev shops are
probably throwing up a little bit in their mouths at this thing. Replace Agile
with "Extreme Programming" and you've got something that looks like it came
straight out of the 90s.
~~~
ntkachov
Really? Just because its structured like waterfall doesn't mean its "how to do
waterfall". I read the req spec and there isn't a thing on here that isn't
valuable information for every engineer no matter what process they use.
Read what it actually covers and the topics they test and tell me there's
something on there that is completely useless.
~~~
spamizbad
Couldn't disagree more. If it looks like a duck, and it quacks like a duck...
I've worked in waterfall shops. Sections I through V are very similar to what
we aspired to do. Look, it's not like this knowledge is worthless. It's just
that what is outlined in these sections is a very thorough but expensive ($$$
and labor) and time-consuming process that that when put into practice often
insulates itself from the business problem at hand. Just because it looks good
_on paper_ does not mean it will look good when you start applying it to the
real world with real people.
I'll say this: If you want to participate in an organization that is
culturally waterfall and practices waterfall this certification will prove
quite valuable. Anywhere else though, and you might give the impression you're
not a good "culture fit" for the organization.
~~~
demian
But "activities" are not "phases". You are always trying to get the
requirements right, the difference is that some people get them while coding,
and others before even start designing.
------
rsl7
I hate it.
The content of that exam is like a list of everything that's wrong with
industry. Those are problems to be fixed, not things to set in concrete as the
way it shall be henceforth.
~~~
AYBABTME
Yes, like requirements, prototyping, user interfaces, minimizing complexity,
profiling and performance, unit-to-usability testing, metrics, refactoring,
performance monitoring...
All that ugly stuff that's wrong with the industry.
~~~
rsl7
Those are problems in the sense that software is a young industry, unlike
other engineering disciplines (or "actual" engineering). We're likely to
abstract away today's issues, whereas matter and physics are more direct,
immediate limitations in engineering disciplines.
We don't have a "software physics".
------
eranation
Yes, because we have too many engineers. It's so hard to choose a good
developer from the hundreds of applicants for each job so we need a 10 year
old obsolete test to filter the good ones out. Talk about waste of money, this
is something I hope is not paid by tax dollars...
------
noarchy
Developers are fortunate that our field has not been swamped by credential
inflation. In other words, we don't even need a degree to do what we do. It is
enough to have a portfolio of solid work and some good references, and high-
paying work can come your way.
The last thing I want to see is for some kind of guild to arise, which could
ultimately lock down the industry (via government requiring licensing, for
instance).
~~~
X-X
While I agree, I think that a large portion of developers want some way to set
themselves apart from the masses - to be recognized as Uber 10X code ninjas.
Those people will never rest till they create their own credentials, whether
it be number of contributions to opensource projects on Github or Coderwall
achievements or a standardized test.
------
eranation
Thinking that taking a multiple choice test will prevent you from causing a
bug that will kill someone is as smart as learning to be a lifeguard from
youtube tutorials.
Organizations that create weapons, spaceships, medical equipment and anything
that can and will kill you if it has any bugs, needs to enforce quality not by
certifying the engineers, but by certifying the organization to follow very
rigid quality criteria. Some companies just have it naturally (perhaps Apple
is a nice example) some companies need a structure (see things like
<http://www.sei.cmu.edu/cmmi/>)
So if this is not for saving lives, then I don't see any purpose in taking or
creating this test.
if you can code, you'll get a job, if your code is bad and has a lot of bugs,
our software cycle is so fast you'll be forced to either improve or switch a
profession. or work on non critical software.
------
tdicola
A software engineering certification exam with no coding seems a little odd.
~~~
demian
That's because in "high brow software engineering", coding is for "workers"
(as in "construction workers").
~~~
barik
Well, the exam for Electrical Engineers doesn't have them build a circuit
either. I assume you're forgetting that you also have to apply to the State
Board, documenting your entire Engineering career, which will be the most
substantial part of the licensing process. I guarantee you that you'll have
plenty of opportunity at this time to demonstrate your programming
experiences.
When individuals ask me for a PE recommendation, I am often reminded in
particular of one of the questions from the PPI2PASS FAQ [1]:
Q: I have been in supervision since graduation. I have never performed a
single calculation.
A: Oops.

despite my disdain for accreditations and certifications, I approve of the
content of the exam. It looks like it covers a lot of ground, in a variety of
subjects.
------
tomkinstinch
What does this mean for people currently working as programmers? Will it be
necessary to study up and get licensed to remain competitive?
~~~
GuiA
It could be necessary to be licensed for government jobs or jobs in large
companies building real time critical systems (ie power grid control software,
avionics, etc). I doubt it'll ever catch on for programming jobs in
mobile/web/etc
~~~
barik
I think it will become necessary for the areas you outline, particularly in
industrial control. Although best practices and standards have been
established for electrical systems and mechanical systems, my observations in
factory control show that the programming components continue to be the most
fragile and buggy. And currently the legislation here lags as well since
software systems are typically __not__ certified, except in certain military
cases.
This isn't something for Web 2.0 programmers, who can carry on as they have
been doing. Instead, it's for folks like myself who have designed the clean-
room door locking logic for the CDC when contamination is detected (see
"Walking Dead" for a grossly exaggerated example of such a system).
~~~
tbranch227
You sound like someone I know. I agree with the above. This cert is definitely
applicable for engineering tasks at my place of business and something I will
probably pursue. It's very beneficial when proposing on harder tasks. Web dev,
which I do as well, generally doesn't reach this level of rigor.
------
ilaksh
I am guessing I could answer enough (how many is enough?) of these 80 multiple
choice questions to pass the exam right now.
But it would be nice to have an idea of what other people think is the most
important information in each topic they mention in that PDF (as far as
passing the exam).
So maybe we should create a wiki where we enter in all of the information
people should understand in order to pass the exam?
I created one on Wikia in case anyone is interested.
<http://softwarepe.wikia.com>
Also, question, would this PE exam be the last step in obtaining a Software
Engineering license, or would it be the only step. If its the last step,
exactly what are the other steps? What group would provide a software
engineering license? Would there be any point in me passing this exam, since I
don't even have a college degree?
~~~
barik
It is the last step. The other steps vary by state, but in general, it
requires that you have at least four years of documented and progressive
experience under the direction of another licensed Engineer. You also need to
have taken the EIT, which is a general Engineering exam that covers all
disciplines, not just computers (brush up on your thermodynamics and concrete
mixing!).
If you do not have an ABET degree, then it is still possible to obtain a PE,
but the requirements generally go from four years to sixteen years of
documented experience.
I may be wrong, I don't think this will be a route for Computer Science. It is
more for those individuals who have been programming under other Engineering
hats ("controls", "electrical", "mechanical") but now have a way to take an
exam that satisfies their actual Engineering work. For instance, I might have
fit more under the hat of Software Engineer (since I did a lot of embedded
programming), but had to take the Electrical Engineering exam instead due to
lack of selection.
~~~
prodigal_erik
Don't engineering licenses usually require a bunch of stuff like fluid
mechanics and metal fatigue which are completely irrelevant for reliable
software? I think we'd be better served with more statistics and denotational
semantics....
~~~
barik
The EIT does, because the first portion is a general Engineering exam. It is
generally at the sophomore level of a four-year University. The PE exam,
however, is related to your discipline, though sometimes tangential questions
may appear (some analog circuits on a digital exam).
------
jboggan
Many years ago when I thought I was going to go into patent law (egads) I
ended up taking the Fundamentals of Engineering exam and passing it as an
Engineer-In-Training. Does this mean I can do four years of software
engineering and then certify as a PE?
~~~
barik
Generally, the PE exam itself is considered one of the least difficult
portions of the process, though it's still stressful for certain disciplines.
The PE exam topics are also generally known to lag reality, regardless of
discipline, and often by a decade. It's also open book and some people bring
entire carts of books, though I find that not to be very effective since you
basically only have six minutes per question.
The major part of the application process is that you will need to work under
the direct supervision of a PE, and have increasing levels of documented
responsibility, which is often harder to satisfy. Depending on the state,
three of the five (minimum) of your recommendations must come from licensed
PEs, who need to be able to certify more about you than simply your character.
Usually when threads like this appear, too much emphasis is placed on the exam
rather than the requirements that allow you to sit for the exam in the first
place. The PE license process is not like a Microsoft or Cisco certification.
It took me a good six months to get all the paperwork ready to apply for the
exam. I minimally studied for the exam itself. Consequently, four years ends
up being more like five or six, in my case, due to less than stellar record
keeping.
------
brownBananas
So this just makes it official, right? Or does this affect people currently
employed as Software Engineers?

rprasad
People on HN seem to be misunderstanding the purpose of this exam. This exam
is not for web programmers, or game programmers, or any "startup"-type
programmers. If what you do can be done iteratively without much problem, this
exam is not for you.
This exam is for people who work on very difficult, very error-sensitive, very
high-end stuff that needs to work from the very start: jet planes, medical
devices, spacevessel systems, etc. You don't get second chances with these
types of systems, so this exam is focused on making sure passers know the gold
standard for how coding is currently done in these areas.

And for an (admittedly dated) example of what can go horribly, horribly wrong

The Elusive Universal Web Bytecode - joubert

It got renamed, then somebody made a backroom deal to borrow the new name for
another totally different language in order to trick people into confusing the
two languages, then the other language became much more popular and widespread
than the one that used to be called Oak, totally taking over the browser, and
making good headway at taking over the server too.

That's me. While I was working at Sun in '90-91 on NeWS, we tried very hard to
convince management to hire him to work on HyperNeWS for TNT, but Sun wouldn't
give us a requisition (because they intended to kill NeWS, not save it). So I
quit Sun and moved out to Glasgow to work with him at the Turing Institute on
HyperLook, and ported SimCity to HyperLook.
HyperNeWS aka HyperLook was like HyperCard implemented with PostScript
programming and graphics, plus networking. In that alternate universe,
PostScript would have been the universal bytecode for the web.

~~~
DonHopkins
You might get a kick out of Sun's proposal for "NFS 3.0" aka "NeFS". The basic
idea was to put a PostScript interpreter in the kernel for extensibly and
efficiently executing distributed and even local file system operations. It
not only cuts down on network transactions for the same reason NeWS and AJAX
does, but even locally you can avoid billions of context switches by executing
"find" and tasks like that in the kernel, for example.
The Network Extensible File System Protocol Specification 2/12/90
[http://www.donhopkins.com/home/nfs3_0.pdf](http://www.donhopkins.com/home/nfs3_0.pdf)
(pages in reverse order)
Introduction
The Network Extensible File System protocol (NeFS) provides transparent remote
access to shared file systems over networks. The NeFS protocol is designed to
be machine, operating system, network architecture, and transport protocol
independent. This document is the draft specification for the protocol. It
will remain in draft form during a period of public review. Italicized
comments in the document are intended to present the rationale behind elements
of the design and to raise questions where there are doubts. Comments and
suggestions on this draft specification are most welcome.
1.1 The Network File System
The Network File System (NFS™) has become a de facto standard distributed file
system. Since it was first made generally available in 1985 it has been
licensed by more than 120 companies. If the NFS protocol has been so
successful why does there need to be NeFS ? Because the NFS protocol has
deficiencies and limitations that become more apparent and troublesome as it
grows older.
1\. Size limitations. The NFS version 2 protocol limits filehandles to 32
bytes, file sizes to the magnitude of a signed 32 bit integer, timestamp
accuracy to 1 second. These and other limits need to be extended to cope with
current and future demands.
2\. Non-idempotent procedures. A significant number of the NFS procedures are
not idempotent. In certain circumstances these procedures can fail
unexpectedly if retried by the client. It is not always clear how the client
should recover from such a failure.
3\. Unix bias. The NFS protocol was designed and first implemented in a Unix
environment. This bias is reflected in the protocol: there is no support for
record-oriented files, file versions or non-Unix file attributes. This bias
must be removed if NFS is to be truly machine and operating system
independent.
4\. No access procedure. Numerous security problems and program anomalies are
attributable to the fact that clients have no facility to ask a server whether
they have permission to carry out certain operations.
5\. No facility to support atomic filesystem operations. For instance the
POSIX O_EXCL flag makes a requirement for exclusive file creation. This cannot
be guaranteed to work via the NFS protocol without the support of an auxiliary
locking service. Similarly there is no way for a client to guarantee that data
written to a file is appended to the current end of the file.
6\. Performance. The NFS version 2 protocol provides a fixed set of operations
between client and server. While a degree of client caching can significantly
reduce the amount of client-server interaction, a level of interaction is
required just to maintain cache consistency and there yet remain many examples
of high client-server interaction that cannot be reduced by caching. The
problem becomes more acute when a client’s set of filesystem operations does
not map cleanly into the set of NFS procedures.
1.2 The Network Extensible File System
NeFS addresses the problems just described. Although a draft specification for
a revised version of the NFS protocol has addressed many of the deficiencies
of NFS version 2, it has not made non-Unix implementations easier, not does it
provide opportunities for performance improvements. Indeed, the extra
complexity introduced by modifications to the NFS protocol makes all
implementations more difficult. A revised NFS protocol does not appear to be
an attractive alternative to the existing protocol.
Although it has features in common with NFS, NeFS is a radical departure from
NFS. The NFS protocol is built according to a Remote Procedure Call model
(RPC) where filesystem operations are mapped across the network as remote
procedure calls. The NeFS protocol abandons this model in favor of an
interpretive model in which the filesystem operations become operators in an
interpreted language. Clients send their requests to the server as programs to
be interpreted. Execution of the request by the server’s interpreter results
in the filesystem operations being invoked and results returned to the client.
Using the interpretive model, filesystem operations can be defined more
simply. Clients can build arbitrarily complex requests from these simple
operations.

> some people don't like some of those things
What does that even mean?
So why did the author throw out LLVM byte code again? It's BSD, it has
bytecode compilers for most platforms browsers exist on (100% vs. 50% speed),
and doesn't rely on a subset of another language. It also doesn't have the
requirement to fall back to vanilla Javascript. As an added bonus, Javascript
could easily compile down to LLVM bytecode.
Seems like the author already preferred their answer and threw out some BS to
"justify" their choice.
JS probably will remain the "byte code of the web", but this article adds
nothing to that trajectory.
~~~
mrec
LLVM's IR makes no stability guarantees - it can change from one release to
the next, with no backward compatibility. That's not ideal for something
you're slinging out to the web.
I believe this is the same reason Khronos defined their own IR (SPIR) instead
of using LLVM's. Needs to be stable.
~~~
CyberDildonics
That is one reason, the other is being easy and fast to process with tools.
------
Rusky
The article makes the argument that existing systems are easier to improve
incrementally, while designing new systems is more work and not guaranteed to
succeed.
The problem is JavaScript-as-bytecode is not especially easy to improve.
Anything you want to add/change that would make it a better bytecode has to be
balanced with the language's use by humans.
The solution to one-VM-to-rule-them-all is not to cram everything into a
higher-level system with lots of assumptions (JavaScript) or to ignore
portability (NaCl, LLVM), but to use a bytecode that's low-level enough to
implement the various assumptions needed by higher layers.
That way both C++ and JavaScript can run at full speed as well as have their
implementations changed (even across websites!) without pushing every change
through the browsers- just like native apps, with the browser providing _only_
cross-platform and security, nothing more.

There are very few cases where human use causes problems. goto is the only one
I can think of. Yet we've gotten loads of great improvements in ES6 to make it
a good compiler target, like float32 and better integer multiplication.

I've pondered this a couple of times. One Ask HN I posted:
[https://news.ycombinator.com/item?id=6773980](https://news.ycombinator.com/item?id=6773980)
A reply to a comment I made on another post says that the CLR and JVM suffer
from GC pauses, which would not be acceptable for web apps.
~~~
fla
GC pauses already occur in most JS engine. They are especially tolerable in a
web app.
------
marcosdumay
I'd settle for a bytecode that supported numbers (instead of only strings),
blocking I/O (in addition to non-blocking), and easy integration with system
(or, in this case browser) utilities.
Javascript happens to have none.
~~~
TazeTSchnitzel
Uh, JS has numbers, blocking IO, and easy integration.
What are you on about?
~~~
marcosdumay
JS implement numbers as strings (has bitten me once).
Last time I looked at, there was no blocking IO at all (there is continuation,
but it does not solve the problem because there isn't any locking mechanism -
yep, I'd like atomic locking at my bytecode too). That's even the main
"selling point" Node.js people throw around as if it was a good thing.
By easy integration I mean the hability of using capabilities available at the
system, but not exported into the language runtime. It can be solved by
something that would let me query the sandbox enviroment for the existence of
a "library" that exports foreign functions, and use it. Also, something that
by the other side lets me write and distribute one such "library" so people
can install them on their browsers let JS use its functionality.
~~~
jdmichal
> JS implement numbers as strings (has bitten me once).
What? JS implements all numbers as 64-bit floating point, which happens to be
able to perfectly represent the 32-bit integer space. It can actually
perfectly represent a 52-bit integer space. See Number.MAX_SAFE_INTEGER [0]
for details.
Now, JS _does_ allow for type coercion between values when using the `==`
operator. Luckily, the `===` operator also exists which eliminates this
effect.
[0] [https://developer.mozilla.org/en-
US/docs/Web/JavaScript/Refe...](https://developer.mozilla.org/en-
US/docs/Web/JavaScript/Reference/Global_Objects/Number/MAX_SAFE_INTEGER)
> Last time I looked at, there was no blocking IO at all.
What does blocking even mean in a single-threaded event-pump context? Does it
mean other events can be processed while the IO executes? Because that's
exactly what an asynchronous AJAX request does. Or does it mean it blocks the
only thread available? Because that's what a synchronous AJAX call does.
Now, if your argument is that JS doesn't have an async / await construct in
order to make asynchronous AJAX look like synchronous AJAX in the code, then
that's in ES7.

Title should be updated to include that this system scans only via IPv4. Doing
such a thing with IPv6 would be a little more surprising. (7.9228163e+28 times
more difficult)
~~~
dsl
There is a false assumption that IPv6 will make mass scanning like this
impossible. In reality you just need to be more clever about it. (Remember way
back when people used "needle in a haystack" security for dial-up systems,
because nobody would ever have the resources to call every phone number in an
area code?)
Link-local multicast (the replacement for ARP) allows tools like alive6 to
very easily enumerate all live v6 addresses on a network. So once a spear
phishing attack is sucessful, you can still scan the entire internal network.
Google hacks like "site:ipv6.*" and passive DNS monitoring allow you to easily
separate used vs allocated/announced subnets on remote networks. IPv6 breaks
in strange ways when you firewall ICMPv6, so ping scanning a subnet has become
much easier.
There was also a great talk (i'll try to dig it up) that talked about
predictable patterns in DHCPv6 implementations, so you can cut down v6 to a
near v4 search space.
The best part of all is that very few security products on the market really
support IPv6 correctly, so I suspect we will see more advanced attacks being
possible because of IPv6 in the coming years than things being stopped.

impossible.
Well, this is an IPv4 brute force search, so technically a IPv6 brute force
search is still impossible.
You are correct though, no one is going scan something that is 99% empty by
brute force.

Here's [1] an example of using Masscan to scan the IPv4 space for shellshock.

gear54rus
I might have missed it while reading the README, but can someone ELI5 why do
we need to randomize our scans?
Can't we just go scan one-after-another IP address? Is this because such scan
can easily be detected by ISP?
~~~
anti-thought
Think of the internet like a tree, where the root is you and all other IPs are
the leaves at the end. IPs close together tend to share more path of the tree
as you attempt to reach them from the root. If you are sending an overwhelming
amount of packets in one direction for too long, you have a higher chance of
harming nodes (i.e. routers) along that path. Randomizing your end goal on the
tree, by definition, equally spreads the packet spray accross the tree.
This is how they can claim: "... it'll only melt your own network. It
randomizes the target IP addresses so that it shouldn't overwhelm any distant
network."
Note "shouldn't", this was probably added due, in part, through use-case. If I
were not scanning the whole Internet, and instead just scan a small section.
Masscan has less of a space to randomize through, which means the tree is
smaller and the shared paths are more frequent.
------
pvnick
How likely is this to be used for anti-piracy efforts? I don't hear much about
en masse copyright enforcement these days, but it seems like the ability to
quickly scan large IP ranges would allow one to periodically (every couple
minutes or so) obtain a list of every single seeded file in the US, at least
for the people not using a VPN.
~~~
Scaevolus
That's not how torrents work. You can't connect to a port on a seeder and get
a list of torrents it's seeding. Even for trackers, you have to request a
specific URL to get a (partial) list of available seeders.
~~~

On the other hand, it is easy to crawl DHT. "Crawling BitTorrent DHTs for Fun
and Profit" (2010) says "We find that we can establish a search engine with
over one million torrents in under two hours using a single desktop PC".

Sorry if I seem naive but, is this even legal? ...

gcommer
I am not a lawyer, but as long as your local laws do not prohibit you from
pinging a given IPv4 address, then I can't imagine any issues. Being
technically legal doens't mean you won't step on some toes though. Everyone
who runs full internet scans has reported getting lots of exclusion requests,
(baseless) legal threats, and even retaliatory DDoS attacks coming back at
their source IPs.
Massscan ships with an exclude list which you would do well to utilize:
[https://github.com/robertdavidgraham/masscan/blob/master/dat...](https://github.com/robertdavidgraham/masscan/blob/master/data/exclude.conf)
If you try to run an internet wide massscan without this list, it will stop
you and give you a warning about how to use the list. You then either manually
override the warning, or use the list.

Meltdown patch reduces mkfile(8) throughput to less than 1/3 on OS X - mpweiher

I have a suspicion that APFS is partly to blame. When I saw benchmarks of APFS
vs. HFS+ [0, 1], it appeared that Apple had managed to transition to a
filesystem that is markedly slower at reads and writes than the 20 year old
one it was replacing.

As I wrote in the article, I already accounted for this. The raw combined
performance degradation was 4x. APFS itself seems to be around 20%. Now that
is somewhat rough, as APFS degradation may itself by non-linear. However,
others have measured the pure APFS costs and they seem to be roughly what I
saw:

This is an utterly pathological test case. mkfile makes a lot of syscalls
which do very little work. Heck you could have made the batch size 1 byte;
that would really show a slowdown!
------
davej
Can someone who is more familiar with Meltdown speculate on this? Is this a
quick fix and is it likely to be optimised over time and become less slow? Or
is this the raw trade-off and current hardware will always suffer slow-downs
to this degree. Can an OS be rearchitected in ways that would mitigate the
performance loss?
~~~
jsheard
> Can an OS be rearchitected in ways that would mitigate the performance loss?
The performance loss comes from extra overhead on syscalls, so it could be
sidestepped by allowing programs to do more work per syscall.
At its simplest that could mean adding more syscalls that perform the same
operation over an arbitrarily long list of inputs (like linux's sendmmsg) but
I would like to see kernels take inspiration from modern graphics APIs that
allow arbitrarily long lists of _arbitrary operations_ to be batched and
executed with a single syscall. GPUs had this stuff figured out years ago.

Bitcoin_McPonzi
Just as a reference point, I didn't see any measurable slowdown on mkfile
(New-Item) throughput on Windows 10 after applying the patch. I suspect this
may be more of a filesystem issue.
I also tried this:
$f = new-object System.IO.FileStream c:\temp\test.dat Create, ReadWrite
$f.SetLength(8GB)
$f.Close()
with no speed difference on a patched and unpached system
~~~
luckydude
So I'm not a Windows expert but I've done file system work. If windows is
reasonably smart it will support files with unallocated blocks. Setting the
length to 8GB is not the same as writing 8GB in any reasonable file system.
I'd retry with a script that actually writes the data.
~~~
cmurf
NTFS and APFS support sparse files, HFS+ does not.
------
raimue
The headline is completely bogus. The author switched both the filesystem from
HFS+ to APFS and the Meltdown patch was applied. This effect cannot be
attributed to just one of them without further testing.
~~~
netgusto
I applied the patched on both my systems (iMac 2013 core i7 on Sierra under
HFS+ that was upgraded to High Sierra for the occasion, and a MacBookPro 2017
already on High Sierra under APFS), and I can confirm that _both_ my systems
are seriously and objectively slowed down, 4 days after the patch now.
From what I could observe, applications taking the most serious hit are
electron based (like VSCode, that went from smooth as silk to mildly sluggish)
and Safari.
Docker on mac has also taken a hit, although I couldn't quantify it
objectively.

I wonder if the inefficiency of the meltdown patches will incentivize cloud
providers to lower the price of large instances that have a high CPU core
count (relative to small instances with low core count).
At the moment, the price of instances goes up linearly relative to CPU core
count - Maybe in part because the performance overhead of virtualizing a
single 32-core machine into 16 2-core machines had been minimal. But now that
the performance overhead of virtualisation is higher (due to isolating the CPU
cores being more expensive), maybe it's more efficient to lease entire CPUs
(with all of their cores) without the patch (and associated overheads).
~~~
tedunangst
If performance is better, why would they charge less instead of more? Why
apply the discount to the more desirable product?
~~~
bobwaycott
My initial guess would be to align pricing with expected performance, which
has now degraded, right? I don’t expect it to happen, but I can see customers
like myself being unhappy with paying—just for example—for an 8-core VPS whose
performance now matches what previously was 4-core performance. So, I don’t
think anyone would expect them to charge less for a higher core count than
lower core count, but adjusting prices downward to match performance wouldn’t
be upsetting.
~~~
jondubois
Yes exactly. To clarify my point; this vulnerability only affects you if
you're sharing a physical machine/CPU with other users (isolated by a
virtualization layer)... So if you choose not to share your physical
machines/CPUs with other users then you are not exposed to that vulnerability
and ideally you also shouldn't need to get these patches and their associated
performance overheads.
Virtualization already has some known minor performance overheads but now
these patches will add even more overheads.
Can cloud providers keep pretending that 4x 2-core virtual instances are as
performant as a single physical 8-core instance?
------
ageofwant
I find it really unhelpful that these 'threads' are being hyped with little
reference to any sort of thread model, reasonable attack vector or
probability. I do not want the kernel on my Arch laptop patched and slowed
down to mitigate against issues that does not reasonably exist in the context
of a laptop user.
By all means patch my browser that runs random js. I'm not in the habit of
downloading and running untrusted binaries - those that do have far greater
problems than Meltdown or spectre already.
Of course I want it patched on AWS, and my bank's backend machines, but you
are now forcing me to continually pay, hour after hour, for insurance against
a thread that I'm happy to not worry about.
Do not steal my cycles to pay for 'security' I do not require.
~~~
megous
Not sure why you're downvoted. It's a perfectly reasonable trade off.
I'll be searching for ways to disable most of these mitigations too after the
dust settles. I rarely run untrusted code, and for that I can probably find a
way to run it securely depending on the perceived threat. A lot of what I do
on my main computer is syscall heavy, and I don't like 25-50% performance hit.
~~~
tzs
You could switch to TempleOS. :-)
Meltdown is a much smaller (but not zero [1]) security risk on TempleOS than
it is on Windows or Unix and Unix-like systems.
[1] At first one might think there is no risk, because TempleOS runs
everything at ring 0 in a single address space so anything that might be
exposed via Meltdown is already wide open. That would be true in the case of
running untrusted binaries. Where Meltdown would still affect TempleOS is in
in the case of trusted binaries being exploited via techniques such as return
oriented programming. Meltdown could make more "gadgets" available in the
binary, increasing the chances that someone could make it read something it
otherwise would not have read.

What are some of the great insights that you got from your heatmaps? - cheekusm
For example, I found that replacing animated user images with real user images in testimonial section has increased the attention span of the testimonial section by 3X. Looking for similar insights?
======
XCSme
Using heatmaps from the [https://usertrack.net](https://usertrack.net) tool on
its own landing page I usually notice:
* What buttons in the header are actually needed/clicked/hovered [https://i.snipboard.io/UShRbI.jpg](https://i.snipboard.io/UShRbI.jpg)
* What non-clickable elements users try to click on (eg. product images, they expect to get a lightbox, but nothing happens)
* If a specific UI element is visible enough and users know it's interactable [https://i.snipboard.io/nJ7AlX.jpg](https://i.snipboard.io/nJ7AlX.jpg)
I personally find the session playbacks a lot more insightful, because
heatmaps don't really tell the whole story, but a session playback can show
you in what order do your users read the page, what are they trying to do,
what are their last actions before they leave your site, etc.

The next stage for Letters is to focus on scalability and extend functionality to make letters sent from our platform more personal, helpful and even entertaining. We'll be adding games that users can send to their loved ones such as Sudoku, Crossword puzzles and even potentially pop-out board games (TBD). Also, we'll be adding different formats for mail, such as Postcards.<p>In the coming months, we'll be planning and developing Connect, which will be the first-ever free platform for sending messages and having video calls with incarcerated people.

out to thank us and describe Ameelio’s impact on their lives:

I live in Australia and my husband is incarcerated in PA, so obviously
communication is a massive part of our relationship, especially in written
format. One factor that most USA residents doesn't have to face, is a monetary
factor of sending snail mail, for me to send a card or letter from here to
him, it's costs me $3.20 AUD, over $2 USD, so Ameelio is such a cost saving
thing for us. I love how informed we are of the status of the letter and that
I can send a pic every single time. It's helped me hold things together for us
as a couple. When the facility was on total lockdown, mail was still getting
thru, but letters I'd sent from early April have only just arrived, yet
letters I sent via Ameelio all arrived within a week (at worst). It gave hubby
peace of mind knowing I was okay out here and that I was thinking of him in
there. WIthout those letters, who knows what his mental health would have been
like. Thank you Ameelio, we both appreciate this wonderful service.

ring road. You can genuinely feel the difference when you take a train into
the city and vice versa.
~~~
quickthrower2
Is that allowing for the time difference between when you get on and get off
the train affecting the temperature?
~~~
gavia1
Absolutely. If you so wish you can take the train at noon and get off at 12:30
where any temperature difference due to the sun should be minimal.
~~~
majewsky
Not terribly relevant to your point, but: Noon is actually a time in the day
where it is still getting warmer. Temperature usually peaks around 16:00 or
17:00 in the summer.
Example:

any idea why? The ground starts releasing accumulated energy or what?

gavia1
It probably reaches saturation at that time of day where it can no longer
absorb anymore heat.

Uhhrrr
From the article: 'If the urban heat island theory is correct then instruments
should have recorded a bigger temperature rise for calm nights than for windy
ones, because wind blows excess heat away from cities and away from the
measuring instruments. There was no difference between the calm and windy
nights, and one study said that "we show that, globally, temperatures over
land have risen as much on windy nights as on calm nights, indicating that the
observed overall warming is not a consequence of urban development."'
This is really surprising to me. Not least because, on a sunny day, SF can go
from pleasant to brutal as soon as a breeze kicks up.

I think it has quite an effect in the summer because the city is cooled by
being near the ocean but the western suburbs get super hot, so a 10 degree
difference might not be unusual at times, for two places about 30km away.

TTIP: Transatlantic Trade and Investment Partnership- a secret deal between US
and EU
~~~
sandstrom
It's correct that much of the details are secret, but I'd stay it's still more
correct to label it as a free-trade agreement than a 'secret deal'.
I think it's insane that negotiations aren't public, and I also disagree with
some of the contents being discussed. But I think it's more objectively
described as a free-trade agreement (in which there are also a lot of good
parts).
~~~
dhimes
That's a fair point, but since we are all pissed off at our governments for
taking liberties with our well-intentioned permission to conduct espionage on
behalf of our well-being, your are extending more benefit-of-the-doubt than a
lot of us are. That's probably to your credit. But I am wary that the 'secret'
stuff has a lot of implications that are only on the edge of what we would
think of as trade agreement- intel sharing and such.
It _could_ , I suppose, be a positive: everybody come clean about the
past(keep that stuff a secret) and then have fair and reasonable limitations
going forward. There was a day when I thought like that... :)

Dwolb
Does anyone know credentials of the people negotiating these deals? Are they

Based on ExpiredLink's comment elsewhere in this thread, it doesn't seem like
the deal is secret at all? Here's the EU page on it:

I said this before, but the closeness of the vote has _nothing_ to do with how
close the vote actually was. Once the whips figure out if a bill is going to
pass or not, they then let people vote however will get them more money.
~~~
bargl
I'm curious how whips work. Do you have anything I could read up on it to
learn more? It makes sense from a certain perspective, but does that mean that
they decided to look into how many people were going to vote no for sure
(which was 217). Then the remaining legislators would get more money if they
voted yes (205) or maybe they voted yes because it was what their constituents
wanted. That's all speculation but it's seriously interesting and very
disturbing.
~~~
diminoten
Once you know a vote isn't going to happen, the voting gets rearranged to look
good. Since the outcome is the same, it doesn't really matter how the outcome
happens, so long as the 'yes' or the 'no' is still a 'yes' or 'no'.
And it's probably one of the least improper things that happens in US
government.
I'd also like to take a moment to explain why this vote doesn't have a chance,
ever, and it's the exact same reason all spending cuts to defense don't
generally go through - all it takes is one bad thing to happen, and suddenly
every single person who voted to reduce defense spending/the NSA budget is at
risk in their district.
It's the easiest attack ad in the world to construct: "My opponent was one of
the people who took away the NSA's power to defend this country, and as a
result we were attacked again!" That's a guaranteed and immediate hit that's
very easy to understand. What's _much_ more complicated is the 'yes' argument.
It's nuanced, confusing, many constituents don't even want it, and in general
a big risk.
The _biggest_ win for members of congress is if no change actually happens,
and yet they still get to have a voting record that shows they're against what
the NSA is doing (exactly how it turned out). Those "yes" votes were probably
pretty damn expensive for the congresspeople who got them, but they'd be HUGE
liabilities if the vote actually passed.
In other words, 'yes' votes were worth more if the 'yes' lost.
~~~
Amadou
While that is all true, it is still worth noting that worst case they still
cared enough to be disingenuous about their voting records.
If they believed that they could just get away with sweeping it under the rug,
they would not even have tried to manipulate the optics of the vote. That's
still a victory in the face of all the propaganda downplaying the importance
of the issue.
~~~

They _are_ getting away with sweeping it under the rug. You're being pandered

The NSA spying program is horrible, yes. And I think it should be halted
immediately. But we need the NSA—they do important things for this country
despite the bad clout they've received because of this one domestic program.
That program is minuscule in size compared to the sum of the important
operations that are conducted in the agency.
I want to make myself clear. I think the domestic intercepts are 100% wrong
and unconstitutional. That needs to stop. But that agency is home to smart
people who do other necessary work to protect us.

~~~
jasonkolb
I'm just trying to get random people to respond. I would refer to gknoy's
comment about how easy surveys are to manipulate, and question whether the
survey you mention was created with a purpose.
I've been working with some research companies lately and one thing which
surprised me was the fact that surveys are often constructed with the sequence
of questions carefully set up to test various messages. Unless you can see the
survey itself, I would question the results.
For example, the question prior to 'How do you feel about the NSA’s accessing
of telephone call records of millions of Americans through secret court
orders' might have been 'Is it important that the NSA’s accessing of telephone
call records of millions of Americans has stopped terrorist attacks?' This
type of question can mightily swing the outcome, so if you don't have access
to the survey you need to ask yourself if the organization putting out the
survey has an agenda...
~~~
rayiner
What do you mean "random people?" What sorts of sites are you posting the
survey to? If people like my mom aren't part of your survey demographic, your
methodology is flawed.
The Washington Post-Pew survey is detailed (through a link) in the article,
specifically this question:
"Q: As you may know, it has been reported that the National Security Agency
has been getting secret court orders to track telephone call records of
MILLIONS of Americans in an effort to investigate terrorism. Would you
consider this access to telephone call records an acceptable or unacceptable
way for the federal government to investigate terrorism?"
58% responded 'acceptable' and 41% responded 'unacceptable'.
~~~
Amadou
FWIW, I think the WAPO-PEW phrasing is slightly biased in favor of the NSA. I
think the following would be more accurate and thus more closer to neutral
(italics indicate changes):
"Q: As you may know, it has been reported that the National Security Agency
has been getting secret court orders to _collect_ telephone call records of
_nearly all American cell phones_ in an effort to investigate terrorism. Would
you consider this _collection of_ telephone call records an acceptable or
unacceptable way for the federal government to investigate terrorism?"
What isn't clear to me is if the phrasing has changed from the survey a month
ago to the most recent survey. If the phrasing (of the entire survey because
cross-question context is important) is not identical then the results just
aren't comparable no matter what biases may or may not be built into the
questions.

Great site. I was able to research and find that Congresswoman Kyrsten Sinema,
serving Arizona's 9th District was cosponsor of the Amash bill but voted
against the amendment, stating that it "has an unintended consequence".
Her press release is full of wonderful contradictions and weasel words:
[http://sinema.house.gov/index.cfm/press-
releases?ID=b23deeab...](http://sinema.house.gov/index.cfm/press-
releases?ID=b23deeab-d42e-4a22-808c-787ef7190761)
From:
“I have very real concerns about the federal government’s action and lack of
transparency regarding the collection and retention of law-abiding Americans’
private information. "
Straight to:
"I believe that we must work toward less intrusive methods to ensure our
security. The broad language we considered today could have limited the
ability of our national security and law enforcement community to prevent the
bombing plot against the New York subway system or to quickly respond to
events like the Boston bombing."
Wrapping it all up with:
"There are other ways than the invasive collection of metadata to ensure the
security of Americans while protecting our precious 4th Amendment rights.”
Ok... so there are other ways, gotcha.... but you don't vote for an amendment
which would have forced the NSA into using / finding other ways. Cool.
Edit: I give her props for responding to my tweet though:

Does anyone find it ironic that the same folks who are anti-libertarian (not
necessarily the HN crowd) and anti-tea party are strident supporters of a tea-
party favorite congressman's amendment. The idea that such a group would rally
around someone who they would not have voted for, seems strange.
I am not sure if I should be proud that a citizenry can see past politics and
rally based on substance, or if they are totally out of touch with how
politics works.

Representatives up for election in 2013 [EDIT: 2014] should be flagged. Ones
in competitive states should be at the top, with donation links for those who
voted Aye. If they voted Nay and their competitor is anti-NSA, their
competitor gets a donation link by the incumbent's name.

> Representatives up for election in 2013 should be flagged.
That's going to be a pretty short list, as regular elections for all seats of
the House of Representatives (and one-third of the seats of the Senate) occur
in every even-numbered year.
The only House elections in 2013 would be special elections, which would
normally be to fill a _vacant_ seat, and thus would not have an incumbent
running.

From their security page:
_We are very secure and make sure to cover many angles to insure your data
can never be compromised. Many often ask what exactly we do to make the data
so secure. Unfortunately, one of the things that makes the site so secure is
that we do not disclose the exact encryption practices._
I just threw up in my mouth a little.
It's also a bit weird that it's apparently two unrelated products in one.
Pinterest and LastPass: two great tastes that taste great together?

justauser
This is quite an eye-opener too...
"How secure is MySocialCloud.com? From day one, it has been our goal to
provide the best security on the web. While we don't expose how we keep
MySocialCloud secure (if we told you, it would be unsecured!), we do ensure
that not even our employees are able to see any of your sensitive data."
One of their videos shows a bookmarket so I'm going to presume they're using
that for somekind of encryption clientside with AES???

richardv
This is ridiculous. I actually started reading with a really positive mind,
but Richard Branson is never going to see any of that $1M.
\- Scott... got the idea when his computer crashed and he lost a spreadsheet
containing all his usernames and passwords.
Using this as a story to explain his startup is awful. So, you are running a
tool to manage passwords, where you previously stored everything in a
spreadsheet? This guy obviously knows a lot about security. Where can I sign
up?
~~~
toyg
That's harsh. I have to say, his pitch resonates with the common man more than
you think. How many people keep their passwords in spreadsheets or other
haphazard ways? Zillions. How many stop and think "mh, what's gonna happen if
I lose this spreadsheet"? Not many -- otherwise they wouldn't store passwords
in spreadsheets to begin with. Scott just reminded them that they'll be
screwed at some point, and he's here to help. I expect part of the reasoning
behind Branson's investment is that the man himself (or some of his minions)
must have had the occasional lost-password-crisis here or there.
Clearly, with a bland but fairly descriptive name like MySocialCloud, they are
not targeting paranoid geeks (the ones who worry about details like "who's
running this service?", and would rather use services going by dorky names
with random missing vowels), they are targeting the common man who stores
passwords in spreadsheets. They are scratching an itch they themselves had,
which is often how you validate your own business plan. I don't see why they
should be ridiculed for it.
(This said, the whole post is just planted marketing of the lowest quality.
Hardly HN-worthy, if you ask me.)
~~~
lelele
> Scott just reminded them that they'll be screwed at some point, and he's
> here to help.
Problem is: he doesn't know how to help, yet people are going to trust him
because they don't know better. I'd bet they are going to store their users'
password on an Excel spreadsheet, but they will take care to backup it often
;-)
There is LastPass already, and they are doing a great job. Competition is
good, but why should we support clueless competitors?
That said, I'd bet MySocialCloud.com will succeed. Worse is better, isn't it?
And now they have lots of money.
------
coderdude
There's a lot of over-the-top hating from the peanut gallery in this thread.
I'll balance it out:
What a ride this must have been so far. They're doing a great job getting
their name out there, that's for sure. An investment from Richard Branson and
a co-founder of Photobucket, plus this article in Yahoo Small Business that is
now trending the HN front page. I hope they're able to take this massive
opportunity they've been given and turn it into a successful business.
------
elmuchoprez
Regardless of whether this is a good idea or not, to say they "turned a tweet
into $1 million" is a bit of a reach.
They saw a tweet advertising an event which Branson would be at, borrowed
several thousands of dollars from their parents to attend the event, and used
that opportunity to get an email address that was capable of reaching Richard
Branson, which they used over a period of time to develop some sort of
relationship with him and another (Murdoch), and through a series of pitches
both in person and remote, they secured initial funding.
~~~
mkramlich
... in a time when investors are desperately seeking anything to throw their
money at that will get good returns. And it's hard to find software engineers.
And, especially to less sophisticated investors, they just know "social" and
"cloud" are the hot hot thing so they want to park some bets in something with
those words involved. Thus... MySocialCloud.com
------
jakeonthemove
I just checked out the service and I don't understand what's with the hate?
It's a Pinterest/Delicious/LastPass mashup, and while I would not trust them
with my passwords (they really should rephrase that explanation, or give a
real overview of their security measures), there are plenty of people who will
(my parents still store their passwords in simple text files :-)).
If they add RSS-reader functionality, I can actually see myself using the site
as a home page!
I believe it's got potential - they'll have to work hard on the marketing and
keeping even or ahead of the competition, though...

Here's a better venture idea based on the experience, "Scott... got the idea

How about designing computers that crash when users try to store usernames and
passwords on them. Users will eventually learn to stop doing that.

Ask HN: Is Stripe going to ban Onlyfans for processing adult content payments? - solaarphunk

TLDR: onlyfans uses multiple payment processors, and presumably shuffles
customers to different ones based on risk. The adult payments likely don't go
through stripe.

Launch HN: Tress (YC W17) – Online community for black women's hairstyles - priscahazel
Tress (<a href="https://www.tressapp.co" rel="nofollow">https://www.tressapp.co</a>) is an online community for black women to discover and share hairstyle inspiration, information and tips.
Women upload photos of their hairstyles and share information about their style. Users can discuss how to replicate the look, which products were used and where to get similar hairstyles.<p>We are 3 software engineers who have built health social networks, mobile apps for farmers in Africa, and worked on marketing consumer
brands like Nike. We started Tress because this is a challenge that personally affects us and because it's a big market that is still relatively untapped by technology.<p>Hair is a big deal for black women. We are constantly changing our hairstyles and spend 9 times more on our hair than any other
demographic. We don't just get a regular cut or color our hair. We get drastic! We go from braids to weaves to cornrows and then to our own
hair and then back again. Size, length, style, color, volume of hair, weaves and extensions all differ each time we change our hairstyle.
And we do that often because of the nature of our hair. To give you an idea, these photos are all of the same woman - <a href="https://www.dropbox.com/s/52ew0d8hsxwx0k4/JodianHairstyles.png?dl=0" rel="nofollow">https://www.dropbox.com/s/52ew0d8hsxwx0k4/JodianHairstyles.p...</a> - It's an image from our YC demo day slides.<p>The process of figuring all this out to actually getting a style done is long and broken. Many women spend a ton of time searching for their next hairstyle, then more time figuring out how to replicate the style via tutorial articles/videos or search for a stylist and so on. Tress aims to be the dedicated platform to fix all of this and connect a community of women who often socialize around their unique hair needs.<p>One thing that excites us as software engineers is exploring how to use computer vision to tell if a user has 4a, 4b or 4c natural hair curl pattern or if a hairstyle is a Senegalese twists or Havana mambo twists. We are equally excited to be gathering hair products data and usage patterns around our hairstyles in such an informal sector that technology has barely gotten started in yet. We dream of things like an API that has all the data about the hair products black women have used in the past 5 years.<p>We're looking forward to answering your questions about Tress and discussing startups, software, and of course hair!

michaelbuckbee
This seems like a tremendously clever idea. To me the most relevant phrase
from the text posted above is: "...and worked on marketing consumer brands
like Nike"
Because I think that's what this really is: the launch of a new premium
consumer brand. Tress is capturing consumers at _exactly_ the right time, they
all have purchase intent and it seems targeted really really well.
They can make serious money recommending local stylists, products, etc. and
then turn around and also sell their own branded products.
This is really far outside of what I'm familiar with, but I look at past
things I scoffed at and that are now worth billions [1] and think this might
have a real shot at getting huge.
It all comes down to execution and work, but a really interesting idea even
now.

Cool!
Sounds like you have many interesting problems, on top of the usual fun
challenges of running a social network+cross platform app. Computer vision,
recommenders for hairstyles, products, stylists, and probably many more. Then
you have usage information about all of those you could use in a bunch of
ways.
And you can monetise with simple, relevant, products ads, or get a commission
off booking a stylist, or collaborate with a booking platform like TresseNoire
(although that's NYC only for now I guess). So that's a lot more options than
many YC backed startups.
A few questions. Feel free to ignore them if there are too many.
It says you're hiring engineers and designers on your website. Care to go to
into more specifics about what kind of positions you're hiring for?
Semi-OT in the "only care about users" YC world, but just curious, what's your
stack?
It says on your website that you're based in Ghana. Do you plan on going back
there after YC, or staying in SV to make it easier to find tech workers+VC
money, or have a foot in both places?

Hi, I'm the Engineering Lead at Tress and we're a lean team of 3. Right now,
we're looking to hire 1 Front End Engineer as we want to launch our web
version for SEO (we realised that Google App Indexing is not enough and we're
missing a lot of SEO opportunities on the web), 1 iOS engineer and 1 UI/UX
designer.
Our top level stack is Ruby on Rails, Postgresql, Redis, AWS, Heroku, Java,
Objective C & Swift.
We initially tested our product in Ghana. But our user base has grown since
and our users are from all over the world with a significant majority from
Africa and the US. We are and will be based in Silicon Valley going forward.
It's a global app and our goal is to have our foot placed globally

Great idea. You mention how much time is spent on looking at/for styles (incl.
members of my family) but I'm not sure everyone here is aware of the average
spend on hair and hair-related products: Mintel estimates the 2016 spend on
black haircare products is about $2.5BB.
Not included in this number (and typically underreported because many services
are rendered in non-official salons) hairstyling services. When family members
go to the 'salon' it often involves many hours and hundred(s) of dollars for a
single visit. Haircare expenditures are a significant budget item - no matter
how wealthy.
I'll pass the app on to my family. Let's see what they say.

Why are you launching here and not on a facebook group dedicated to such
market? There are also instagram micro influencers (less than 10k followers)
you could also leverage...
Not being a hater but launching here seems silly from the POV of marketing.
This seems like something that would get traction rather quickly if pushed in
the right context.
Trust me. Put ads on facebook with your target demographics and search IG for
women of color with a good amount of followers. That stuff works like magic.
Edit:
If you email me I can introduce you to one such group that has a lot of active
users and is led by a black lady. You can pivot from there.

Just realized my comment makes me sound like a huge dick. Not my intention. Im
excited about the product and wish you the best of luck. I do feel strongly

YC startups are launching as "Launch HN" these days, which is a new mechanism
that we intend eventually to replace some of the job ads that appear on the
front page. It's all a work in progress. But we would have invited Tress to
post even apart from that, because it's so off-the-beaten-track for HN, and
that's what keeps things interesting.
You're right that HN isn't the best place to launch consumer products for
customer acquisition, but there are other reasons to launch on HN, such as
discussing ideas, product feedback, and getting on users' radar for future
hiring. No reason not to do all the launches!
p.s. As a local professional in the 'omg that's bad' department I can assure
you that it's always the good users who worry about sounding like a dick :)
Your comment shows how an excess of enthusiasm can sometimes come out the
wrong way temporarily, but explaining it as nicely as you did makes it all ok.

Their address by the way:

I used to live in Ghana. Addresses are landmark-based as nobody knows street

Interesting topic and I can see how this is a daily issue for some, but I
don't get the startup angle. What's the eventual monetization angle? Referrals
for hair stylists? Paid membership to get new lists of or customized styles?
Which of the pictures of the girl (linked to the dropbox share) is closest to
her natural hair? The styles are so varied it's impossible to tell! On the
aesthetic front (obviously IMHO) it's a toss up between Oct 2016 and Dec 2016
for best (though all look very nice!).
~~~
priscahazel
We will monetize through product sales, stylists booking/referrals like you
mentioned and native ads targeted at specific hair types within the black
hair-care community.
With regards to your second question, the closest to her natural hair is the
1st pic (Nov 2016). Hers will be much shorter and will have to be straightened
to look like this. It's surprising that none of the styles show her own hair.
~~~
wehadfun
I would avoid trying to charge for bookings. You will be the victim of
Disintermediation because the stylist will tell give the client their number
and say to not use trees to book.
I would suggest charging stylist to attached their searchable location and
phone numbers to picture of hair styles. In other words charge them for
advertising.

Could you download and check out the app? There are a lot of nuances and

ksenzee
There's way less of a market in other demographics. For example, white women:
we have less interesting hair. There simply aren't as many things we can do
with it, because the structure of the individual hairs is less complex. Plus
we have every women's magazine in the US and Europe assuming our hair is the
"default." I'd say they know exactly what they're doing aiming at their own
demographic.

Steve Wozniak's First Dance on "Dancing with the Stars" - zeedotme

coglethorpe
OK, I'll admit to watching The Woz dance. I think he moved pretty well for a
big guy, but the judges didn't agree with me.
It was great to hear him go on about how he's used to digital things and how
dance is analog, all while his dance partner's eyes glazed over. He's lost 30
pounds while practicing for the competition, so even if he loses the
competition right away, he's got that going for him.
It's also great to see Woz, who apparently doesn't need the money, doing it
just for fun. He stands out from some of the other "celebrities" who really
are just desperate for a paycheck. It was obvious he was having a blast and
his dance partner said he was the nicest man she's ever met.

======
Ndymium
The English Wikipedia page, to me, seems to suggest that the record was played
to explode the mines in a controlled fashion. In fact, according to Finnish
Wikipedia, it was used to scramble the Soviet radio signals to prevent the
mines from exploding, and there was a sort of radio war going on for a while.
This is the specific record that apparently was used:

When I read "mine", I thought of anti-personnel landmines and was confused why
you'd want to radio-trigger those.
These were demolition charges designed to destroy objects like bridges.

Interesting. This is basically an early version of the phone bomb where you
get a burner phone and just call the number of the sim card to blow it up.
Being able to pull that off in the 40's was impressive.
Hard to say what use it has though? Normally a "mine" is something that is
triggered by an event such as a person or vehicle passing. Setting one off
remotely or on a timer isn't useful.
If the mines were used to rig specific infastructure such as railways or
bridges then I can see the use (blow specific bridges at specific points in
time, without having to send saboteurs). I remember practicing bridge
destruction in the army using dozens of tank mines, simply because they were
readily available and easily handled explosives.
~~~
doikor
These were "mines" used to blow up bridges, roads and railroads. The bigger
ones had thousands of kg of explosives. So more like remote demolition over
radio. Idea being that you could destroy the critical infrastructure after
retreating from the area and if you had vision on it when someone was on it
like the first one that killed a couple officers (killed a major who was the
chief lawyer for the Finnish General Staff)
Modern equivalent would be cellphone bombs in roads in Afghanistan/Iraq.

Each mine could be set to a different combination of three trigger

Nice song. Finnish language is part of the Uralic group of languages Finno-
Ugric spoken by Hungarians and Estonians too.
These languages don't belong to Indo-Iranian group like every other language
in Europe.
I like to speculate the language came to northern Europe with Huns who,
according to Procopius (I believe it was him) controlled Scandinavia too and
there are many sagas of Norsemen fighting Huns there, such as Hlöðskviða.
The modern Finns show Nordic genetic, yet the language is Uralic and perhaps
the first Finns were only the ruling class as it was often the case with Huns.
Obviously, there are other more widely accepted theories.

I'm sorry to ruin your imaginations but genetics, linguistics and history are
real sciences concerned with tangible facts. Unlike some political theories
with no right to claim credibility other than calling themselves "modern."
Aryan (term I didn't use) simply means Iranian, regardless of whether nazis
abused the term or not. You may find it useful to know that.
~~~
philangist
I do agree with your more general point but I think we shouldn't dismiss
changes in usages of words over time. Aryan doesn't simply mean Iranian in a
modern western context, just like the swastika isn't just a sign from Buddhism
or Hinduism. Both have strong associations with one of the most defining wars
of the 20th century and the genocidal regime that started said war. That can't
be easily ignored.

Stop building client-side forms - tvararu
https://blog.vararu.org/stop-building-client-side-forms
======
postpawl
It’s probably worth adding a sentence or two to describe when client side
forms are useful?
Once your form becomes very dynamic (“add another”, conditional
fields/choices, 15+ change events), a server side form will end up needing to
duplicate a lot of form rendering logic on both the front-end and the back-
end. The server side template will need to be able to re-render the form on
initial load, when fields are changed, and when the form is submitted with
errors. The front-end will need all the logic to render form fields to avoid
reloading the page constantly.
A mostly client side form doesn’t need to duplicate the form rendering logic
in server side templates or make a request to the server side to re-render the
form based on a choice you selected. I think this can be simpler and provide a
better user experience for really complicated dynamic forms.
It’s a complicated decision that should be based on how dynamic your form is
and how acceptable page refreshes are. Like a lot of things in our industry...
I wish this post showed more nuance rather than bashing a solution that may be
better in some scenarios.
------
nicbou
There's one important detail you forgot: server-side forms make caching more
difficult. It can be a performance bottleneck.
As already pointed out, dynamic parts require client-side logic.
There's also quite a bit of FUD going on in that article. You can write a
client-side form without loading 200kb of libraries. I write mine in vanilla
JS. It really isn't that hard.

Outraged eBay sellers plan boycott - dcurtis

======
iamelgringo
When, oh, when will someone develop a decent competitor to Ebay? The site is
awful and is ripe for a startup to carve away market share. They've already
proven the business model. We know it makes money. I know the boys at
auctomatic are doing their best to help out, but what's needed is a full on
competitor.
I mean, really. How hard is it to offer a couple of decent looking templates
for people to make their own site, to that it isn't such an eyesore? How hard
is it to implement a better form of search and categorization? How hard is it
to develop a form of authentication to cut down on all the fraud that takes
place on Ebay?
The last time I used Ebay or thought it was decent was back in 97-98. The site
hasn't changed much since.
We should have a challenge to see who can develop the best Ebay competitor.
~~~
gruseom
_The last time I used Ebay or thought it was decent was back in 97-98. The
site hasn't changed much since._
Someone who consulted there told me that eBay's codebase was a mess (even by
the usual standards) and that they had some strange processes that made it
worse. If I recall correctly, programmers weren't allowed to work in teams and
were frequently 'rotated' through completely unrelated projects. He told me
some other weird things that I don't remember, but that combined to form an
impression that eBay's culture is really inimical to hackers. That would
explain their technical stagnation. But overwhelming market share gives them
powerful inertia.
~~~
pg
Back in the 1998 at Yahoo we used to hear shocking things about how bad eBay's
systems were. One of the externally visible signs was their policy of having
several hours a week of scheduled downtime. That seemed just inexcusable. Do
they still do that?
I think the reason eBay is so inept is that they were a monopoly almost from
the beginning. So at a stage when other startups (Google for example) had to
work hard to succeed, they were already coasting, at least technically.

Ask HN: the link to the article ``what makes a good teacher'' - plmday
Hi, I still remember that I read a blog article submitted by someone of you talking about ``what makes a good teacher'' alike, but I can not find the article now. I googled the title, but all the results are not the one I read before. Anyone remember the link to the article? Thanks.
