Can you explain why the following occurs in Python? (The culprit is roundoff, but why does it seem like 1.1 is not affected but 1.2 is?)
>>> (1.1 + 1) - 1
1.1
>>> (1.2 + 1) - 1
1.2000000000000002
>>> 1.2 + (1 - 1)
1.2
Try the same with 1.3 and 1.4

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.
