NetBeans 6 - the only IDE you need
By David Coldrick on Dec 10, 2007
Yes, I know it was released last week, already. Lots of great documentation, screencasts, more screencasts, and the new edition of the NetBeans magazine. Details on new features are here. Take a look at the Ruby and Rails support! Tor, who incidentally is the guy responsible for the R&R support, has done some excellent demonstration videos. Enjoy!
