MacRuby

Marcus Crafter just published a very nice article about using CoreImage via RubyCocoa in Rails apps to handle file uploads, instead of the traditional RMagick and ImageScience libraries.

As the title says, the new version of RubyGems, 0.9.5, now includes Leopard support. You can safely update to this version without breaking Leopard’s Ruby configuration. Updating is trivial: $ sudo gem update --system RubyGems 0.9.5 is a great release so far, do not hesitate to upgrade.

Kudos to Paul Ingles for his detailed analysis of Ruby Dtrace probes in Leopard. Among other tidbits, he includes a nice link to the Joyent “D” scripts for Ruby. Thanks, Paul!

Andy Matuschak has a nice roundup on RubyCocoa examples and Leopard documentation.
