Rails 3 Cliff Notes, Part 1: getting started
Requires Ruby 1.8.7 or higher, but Ruby 1.9.2 is very stable and you should use it for new projects (unless you deploy on Heroku). Use rvm to remain sane when switching between new and old projects. By creating a .rvmrc file, rvm will automatically switch you [...]

September 18, 2010 - 7:39 am
Blazing Cloud is working on a new iPhone application, called Peer Pressure. The idea is that you get your friends to help you achieve your goals. We’re beta testing it and it is at the point where I feel ready to try a public goal.

Evan Phoenix (@evanphx), lead developer for Rubinius, spoke today at the Golden Gate Ruby Conference about how to effectively run or contribute to an open source project. Awesome talk. Great information that is pretty slow to figure out by osmosis.

I was excited to participate in the ReadWriteWeb Mobile Summit last Friday. Elesterama has a nice write-up of the keynote, which was followed by an unconference led by the fabulous Kaliha Hamlin.

Rails3, RSpec2 and WebMock
May 9, 2010 - 2:32 pm
Yesterday we were deep in the middle of coding using RSpec 2 and Rails 3 and needed to verify that a method made a specific http request. I happily discovered WebMock, which appears to be a next generation FakeWeb. Originally developed by Bartosz Blimke, I was happy to see that Sam Phillips had [...]
