Writing node modules with voxel.js

This is a short guide that will teach you the workflows that have been figured out by the voxel.js community for writing node modules + sharing them on NPM and Github. It is assumed that you have a basic understanding of JavaScript, github and the command line (if not you can check out an introduction to git and the command line or learn JS basics from JavaScript for Cats)

The voxel-tower repository on github contains all the example code from this guide.

21:58 < dook> Ok so the basic premise is that to make Chrome run javascript fast, they made a JS->C++ compiler called V8

21:58 < dook> It makes JS compile into very fast, efficient code.

Latency numbers every programmer should know

L1 cache reference ......................... 0.5 ns
Branch mispredict ............................ 5 ns
L2 cache reference ........................... 7 ns
Mutex lock/unlock ........................... 25 ns
Main memory reference ...................... 100 ns             
Compress 1K bytes with Zippy ............. 3,000 ns  =   3 µs
Send 2K bytes over 1 Gbps network ....... 20,000 ns  =  20 µs
SSD random read ........................ 150,000 ns  = 150 µs

Read 1 MB sequentially from memory ..... 250,000 ns = 250 µs
