Latency Numbers Every Programmer Should Know
Latency Comparison Numbers (~2012)
----------------------------------
L1 cache reference 0.5 ns
Branch mispredict 5 ns
L2 cache reference 7 ns 14x L1 cache
Mutex lock/unlock 25 ns
Main memory reference 100 ns 20x L2 cache, 200x L1 cache
Compress 1K bytes with Zippy 3,000 ns 3 us
Send 1K bytes over 1 Gbps network 10,000 ns 10 us
Read 4K randomly from SSD* 150,000 ns 150 us ~1GB/sec SSD
var cluster = require('cluster');
var PORT = +process.env.PORT || 1337;

An example and explanation of how to use lifetimes and borrowing to avoid copying, while maintaining safety.
extern mod extra;
use extra::json::*;
/*
* This function manages to do absolutely no copying, which is pretty cool.
*
* "What are all those `'r`s?" you ask. Well, they're liftime parameters. They
* indicate how long something lasts (before it's freed). They can't change how
* long something lives for, they only allow you to tell the compiler stuff it

The introduction to Reactive Programming you've been missing
# Hello, and welcome to makefile basics.
#
# You will learn why `make` is so great, and why, despite its "weird" syntax,
# it is actually a highly expressive, efficient, and powerful way to build
# programs.
#
# Once you're done here, go to
# http://www.gnu.org/software/make/manual/make.html
# to learn SOOOO much more.

ESLint Reset - A starter .eslintrc file that resets all rules to off and includes a description of what each rule does. From here, enable the rules that you care about by changing the 0 to a 1 or 2. 1 means warning (will not affect exit code) and 2 means error (will affect exit code).
{
// http://eslint.org/docs/rules/
"ecmaFeatures": {
"binaryLiterals": false, // enable binary literals
"blockBindings": false, // enable let and const (aka block bindings)
"defaultParams": false, // enable default function parameters
"forOf": false, // enable for-of loops
"generators": false, // enable generators
"objectLiteralComputedProperties": false, // enable computed object literal property names

Publishing an NPM package

Here's what I do when I publish an NPM package.

1: Make sure you're up to date

I always like to check what's going on in a repo before I do anything:
