Codetown ::: a software developer's community
Just started with Ruby on Rails ( Rails 3) and I'm trying to figure out the best I.D.E. Here's what I've found so far:
Eclipse / DLTK - while researching this on the web I came across a number of broken links which was a bad sign and when I did get it installed I wasn't able to debug using it. Ater some more web searches I came across a few posts that said basically the Ruby plug-in had run out of steam and was not being pursued.
JetBrains/RubyMine - this installed and works, so far the *looks* like the best bet. The instant database diagramming looks really cool, do other I.D.E.s support this?
Ecliplse/Aptana - just got this installed, Will try debugging with it soon.
Does anyone have recommendations for their favorite I.D.E.? I don't need anythgin too fancy, as long as I can set a breakpoint and view variables and the call stack I'm happy. And it helps if its a free product.'

Kevin, What have you found out so far with Eclipse/Aptana and JetBrains/RubyMine? Have you experimented with any other IDE's?
With Eclipse/Aptana I *think* I got installed, but the online references that showed how to start a debugging session accessed menu options that were not present so I was unable to use it. So far RubyMine looks the best, it also checks the syntax of of .html.erb ( Embedded RuBy ) files and generates a diagram of your DB tables, highlighting any relationships that look hinky. Worth noting RubyMine costs money, while the others I've looked at are open source and frankly I think the developers for the free plugins ran out of steam. The profit motive at work.
Codetown is a social network. It's got blogs, forums, groups, personal pages and more! You might think of Codetown as a funky camper van with lots of compartments for your stuff and a great multimedia system, too! Best of all, Codetown has room for all of your friends.

A new CNCF report identifies Kubernetes as the primary engine for AI growth, with 82% production adoption. However, technical maturity has outpaced organisational change. Human factors, such as siloed team structures and a lack of cross-functional collaboration, now serve as the leading barriers to successful deployment, making cultural transformation the decisive factor for AI scaling.

Celebrating its 20th anniversary, QCon’s 2026 conferences in London and San Francisco will focus on the engineering realities of agentic AI, resilient architectures, and platform ROI. The programs continue the series' two-decade tradition of practitioner-led content, curated by senior engineers from companies like Zoox, UBS, and LinkedIn.
