The web is about to explode with exciting new apps. There’s a beta gem out for the upcoming version 0.13 of Ruby on Rails , which contains helpers methods for some crazy AJAX stuff developed by script.aculo.us.
For example, you can make an auto complete text field with TWO LINES OF CODE. Further, Drag ‘n Drop shopping carts are trivial. This stuff is absolutely nuts.
If you’re not into Ruby on Rails, take a look right now. I’m involved in 4 Ruby on Rails projects right now (2 personal, 2 for profit) and the small amount of time I invested in learning RoR is generating amazing returns :)
UPDATE: Ruby on Rails 0.13 has been released! Go get it now!
