I'm looking at the following tools to add to my Ruby on Rails tool chain:
RunCodeRun at runcoderun.com
CruiseControl by Thoughtworks
I'm excited by the products talked about at the NewRelic scalability blog. I saw the first episode and am very psyched about bullet by Richard Huang.
Metrics & Monitoring
Can't wait to try out Caliper for Ruby metrics and NewRelic for monitoring
I'm using SVN on a few projects, but I have been in the promised land and can't wait to get back to git, so let's add GitHub to the list.
