What's Hot on Github is a monthly post highlighting interesting projects that are new or updated this month, within the Ruby community that are hosted on Github. Github has become an extremely popular place for Ruby and Rails developers to congregate lately, so I wanted to list some of the new projects, and some of the updated ones, that I have found interesting and that are too small for their own blog post.

This month's picks:

• http://github.com/karmi/marley/ - Marley is minimal blog engine without admin interface written in Sinatra framework
• http://github.com/evilchelu/braid/ - Simple tool to help track Git and SVN vendor branches in a Git repository (had some nice updates recently)
• http://github.com/purzelrakete/blackbook/ - Blackbook automates the nitty-gritty of importing contacts from various services and files and exporting them as VCard, XML, or simple Hash.
• http://github.com/rsl/acts_as_snook/ - ActsAsSnook is a simple and elegant method of handling comment spam that doesn’t rely on CAPTCHAS or Javascript or external web services.
• http://github.com/courtenay/acts_like_git/ - A Rails plugin that uses Git to version ActiveRecord fields, like acts_as_versioned, but a git.
• http://github.com/xaviershay/enki/ - A new Ruby on Rails blogging app
• http://github.com/jnunemaker/httparty/ - Makes it easy to interact with a variety of web services (previously on Ruby Inside).
• http://github.com/maccman/acts_as_recommendable/ - Collaborative filtering for Rails
• http://github.com/hungrymachine/acts_as_routing/ - Support :acts_as in Rails/Merb routing.

A special thanks this month goes to the Rails Rumble team as they made some great suggestions based on what people had used for their applications.
