  # Class: Vash (Ruby Volatile Hash)
  # Hash that returns values only for a short time.  This is useful as a cache
  # where I/O is involved.  The primary goal of this object is to reduce I/O 
  # access and due to the nature of I/O being slower then memory, you should also
  # see a gain in quicker response times.
  #
  # For example, if Person.first found the first person from the database & cache 
  # was an instance of Vash then the following would only contact the database for
  # the first iteration:

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.

Pagination 101

Article by Faruk Ateş, [originally on KuraFire.net][original] which is currently down

One of the most commonly overlooked and under-refined elements of a website is its pagination controls. In many cases, these are treated as an afterthought. I rarely come across a website that has decent pagination, and it always makes me wonder why so few manage to get it right. After all, I'd say that pagination is pretty easy to get right. Alas, that doesn't seem the case, so after encouragement from Chris Messina on Flickr I decided to write my Pagination 101, hopefully it'll give you some clues as to what makes good pagination.

Before going into analyzing good and bad pagination, I want to explain just what I consider to be pagination: Pagination is any kind of control system that lets the user browse through pages of search results, archives, or any other kind of continued content. Search results are the o
