"I was asked to "upgrade" a relative's machine from Windows XP to Windows 7, so I figured this was a good time to write-up the experience in case it helps others."

Instead of contributing to the mass of tutorials already written about the subject, I figured I would take the easy useful way out and compose a list of great tutorials on how to accomplish a migration to Git for those who are familiar with SVN. If you have more links, please comment away and I’ll add them in.

Rails 3.0 is a landmark release as it delivers on the Merb/Rails merge promise made in December 2008. Rails 3.0 provides major upgrades to all of the components of Rails, including a complete overhaul of the router and query APIs.

During the last year I've ported a number of gems and Rails apps to Ruby 1.9. I feel it's important we as a community get the transition from 1.8 done and over with as soon as possible so we can get back to doing real work. I suspect that many of you have installed a Ruby 1.9 and that it lingers somewhere on your harddrive without much use. Maybe you're even one of those performance trolls, childishly happy reading articles like The Great Ruby Shootout and then goes back to coding in yesterdays Ruby like it's '99. ;)

Migrations bother me. On one hand, migrations are the best solution we have for the problem of versioning databases. The scope of that problem includes merging schema changes from different developers, applying schema changes to production data, and creating a DRY representation of the schema. But even though migrations is the best solution we have, it still isn’t a very good one.

Check the brainstorming at the end. I love where he's going. Short version: a schema.yml file identified by its SHA1 hash. Migrations are for translating data between versions. Great comments at the end by the smart people in the community.
