GitHub OAuth Busy Developer's Guide

This is a quick guide to OAuth2 support in GitHub for developers. This is still experimental and could change at any moment. This Gist will serve as a living document until it becomes finalized at Develop.GitHub.com.

OAuth2 is a protocol that lets external apps request authorization to private details in your GitHub account without getting your password. All developers need to register their application before getting started.

;;Using the Cassowary constraint solver from ClojureScript
;;This demo shows using multimethods for readable constraint syntax using +, -, and =.
;;Output is a row of circles with random radii spaced so that the space between their boundaries is uniform.

Please note: THIS ARTICLE IS NOT WRITTEN BY THE GITHUB TEAM or in any way associated with them. It's simply hosted as a Gist because the markdown formatting is excellent and far clearer than anything I could manage on my personal Tumblr at peternixey.com.

# Demo of Gaussian process regression with R
# James Keirstead
# 5 April 2012

# Chapter 2 of Rasmussen and Williams's book `Gaussian Processes
# for Machine Learning' provides a detailed explanation of the
# math for Gaussian process regression.  It doesn't provide
# much in the way of code though.  This Gist is a brief demo
# of the basic elements of Gaussian process regression, as
# described on pages 13 to 16.

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
