ankane/the-ultimate-guide-to-ruby-timeouts: :clock4:
An unresponsive service is worse than a down one. It can tie up your entire system if not handled properly. All network requests should have a timeout.

Here’s how to add timeouts for popular Ruby gems. All have been tested. You should avoid Ruby’s Timeout module. The default is no timeout, unless otherwise specified. Enjoy!

donmelton/video_transcoding: Tools to transcode, inspect and convert videos.
Hi, I'm Don Melton. I created these tools to transcode my collection of Blu-ray Discs and DVDs into a smaller, more portable format while remaining high enough quality to be mistaken for the originals.

What makes these tools unique are the ratecontrol systems which achieve those goals.

This package is based on my original collection of Video Transcoding Scripts written in Bash. While still available online, those scripts are no longer in active development. Users are encouraged to install this Ruby Gem instead.

nayafia/lemonade-stand: A handy guide to making $$ in open source
"I do open source work, how do I get paid for it?"

Below I've listed every way I know of that people get paid for open source work, roughly ordered from small to large. Each funding category links to several real examples. (Wherever possible, I've tried to link to a useful article or page instead of just a homepage.)

The categories are not mutually exclusive. For example, a project might have a foundation but also use crowdfunding to raise money. Someone else might do consulting and also have a donation button. Etc. The purpose of this guide is to provide an exhaustive list of all the ways you can get paid, so that you can figure out what works best for you.

How to write a great error message — Medium
The 3 most important things when writing error messages

Don’t abuse alerts for upselling or showing superfluous information. People will stop reading the messages that are actually important.

Don’t just assume people know about the context of a message. They might toggle between apps and see your message days after it happened. Always include enough information for users to make sense of it.

Use a friendly, non-technical, non-threatening tone of voice.

TL;DR Write actionable error messages that laypeople can understand.*

*Not sure if they do? Show them to a non-technical person and ask them to explain it back to you.

Is Your Computer Stable?
Everyone breathes a sigh of relief when their newly built computer boots up for the first time, no matter how many times they've done it before. But booting is only the beginning of the story. Yeah, it boots, great. Color me unimpressed. What we really need to know is whether that computer is stable.

Although commodity computer parts are more reliable every year, and vendors test their parts plenty before they ship them, there's no guarantee all those parts will work reliably together, in your particular environment, under your particular workload. And there's always the possibility, however slim, of getting very, very unlucky with subtly broken components.

Because we're rational scientists, we test stuff in our native environment, and collect data to prove our computer is stable. Right? So after we boot, we test.

JSON API — A specification for building APIs in JSON
If you've ever argued with your team about the way your JSON responses should be formatted, JSON API is your anti-bikeshedding weapon.

By following shared conventions, you can increase productivity, take advantage of generalized tooling, and focus on what matters: your application.

Clients built around JSON API are able to take advantage of its features around efficiently caching responses, sometimes eliminating network requests entirely.

These pages show 8 different sorting algorithms on 4 different initial conditions. These visualizations are intended to:

Show how each algorithm operates.
Show that there is no best sorting algorithm.
Show the advantages and disadvantages of each algorithm.
Show that worse-case asymptotic behavior is not always the deciding factor in choosing an algorithm.
Show that the initial condition (input order and key distribution) affects performance as much as the algorithm choice.

Enough With the Salts: Updates on Secure Password Schemes - Blog - Matasano Security
When it comes to password storage, you’re much better off using a well tested and reviewed system than writing your own. You’ll want that to be something purpose built, rather than relying on fast cryptographic hashes which are especially susceptible to fast guessing and hardware optimization. This means you’ll want to use scrypt, bcrypt, or PBKDF2 (in my order of preference) with an appropriate work factor. If you’re stuck deciding between scrypt and bcrypt, you can pretty much flip a coin and end up with something reasonable.

The God Login
How would God build this login dialog? The answer is, of course, God wouldn't bother to build a login dialog at all. Every user would already be logged into GodApp the second they loaded the page because God knows who they are. Authoritatively, even.

This is obviously impossible for us, because God isn't one of our investors.

But.. how close can we get to the perfect godlike login experience in Discourse? That's a noble and worthy goal.

Caso você seja tributado em uma compra internacional cujo valor seja abaixo de US$ 100, a recomendação é entrar com um pedido de revisão. O site disponibiliza dois modelos de carta (arquivos DOCX), um para compras abaixo de US$ 50 e outro para compras abaixo de US$ 100. Esses documentos devem ser preenchidos e entregues à Receita Federal para que o valor de tributação pago seja reembolsado.

Caso isso não aconteça, a solução é entrar com uma ação no Juizado Especial Federal. Como o valor da causa a inferior a 20 salários mínimos, não é necessária a presença de um advogado. Para entrar com uma ação, é necessário preencher o modelo de documento (arquivo DOCX) que pode ser baixado neste link.
