The Ruby Show

Show Notes

Episode #091. I'm joined again by Dan Benjamin and we have quite a fun time. You may know Dan from his compiling Ruby, Rails, and MySQL guides, cork'd, and most recently Playgrounder. We've got a ton of great content this week and we tried to keep it a bit more brief than last week.

The Rails Envy podcast is brought to you this week by NewRelic. NewRelic provides RPM which is a plugin for rails that allows you to monitor and quickly diagnose problems with your Rails application in real time. Check them out at NewRelic.com.
