Array iteration early exit options -- best options are lodash.forEach or Array#some.
/**
* Use `Array#some` when it is convenient to exit on truthy return values
* Use `lodash.forEach` when it is convenient to exit on false (you can cast if necessary with `!!`)
*/
var _ = require('lodash');
var numbers = [1, 2, 3, 4, 5, 6];
console.log('Array#forEach (result not as expected)');

Get a Python subprocess' output without buffering. Normally when you want to get the output of a subprocess in Python you have to wait until the process finishes. This is bad for long running processes. Here's a way to get the output unbuffered (in real-time.)
import contextlib
import subprocess
# Unix, Windows and old Macintosh end-of-line
newlines = ['\n', '\r\n', '\r']
def unbuffered(proc, stream='stdout'):
stream = getattr(proc, stream)
with contextlib.closing(stream):
while True:
out = []

transcode video streams using node.js Streams and avconv (aka ffmpeg)

The avconv utility can be made to work in 'the Unix way' by specifying stdin and/or stdout instead of filenames for the input and output respectively. See: http://libav.org/avconv.html#pipe

Example:

cat input.ts | avconv -i pipe:0 -f mp4 -movflags frag_keyframe pipe:1 | cat > output.mp4

Using node's require('child_process').spawn(), we can pipe streams of video data through avconv's stdin and stdout and thus Stream All The Things.

var fs = require('fs');

Routes

小心地使用 Match(Rails 3 已实现)

Rails 3 提供了 match 方法供我们自定义 routes,然而我们要小心使用它以避免“跨站脚本攻击”(XSS Attack)。比如像这样的 routes:

注:(r3 代表 Rails 3,r4 代表 Rails 4)

Why it was moved

Github gists don't support Pull Requests or any notifications, which made it impossible for me to maintain this (surprisingly popular) gist with fixes, respond to comments and so on. In the interest of maintaining the quality of this resource for others, I've moved it to a proper repo. Cheers!
