Double Shot #631

Things are very nearly too busy, but there's still time for a few links.

• Rails Quick Tip: Readable Conditional Validation - Useful little bit of code from Michael Bleigh.
• MyGem.configure block - More syntax, this time for gem authors.
• fog - Gem to make it easier to work with cloud services (Amazon and RackSpace so far).
• A successful Git branching model - Nice writeup of use of git in a team situation.
• sinatra-pages - Sinatra extension for view rendering.
