Bugs
Getting Started
I recently started experimenting with Ruby on Rails. It's totally awesome. I've also been reading the beta version of Agile Web Development with Rails (errata) which is even more totally awesome.
Useful Utilities
DBVisualizer - I was recently looking for a tool that would allow me to visualise a PostgreSQL database. DBVisualizer does that and much more. This is an extremely useful application and a very good example of what a Java application should look like.
Code
RailsTips/Sessions - Store session information in your PostgreSQL database
RailsTips/FileUpload - Upload files that are stored on the file system instead of in the database
RailsTips/JumpBack - Send the user further back than their previous page
Editors
Emacs with ruby-mode
Usable.
KDevelop
KDevelop in Fedora Core 4 has a very nice Ruby mode. I'm currently using this for my development.
jEdit
jEdit also looks very promising. I haven't used this myself though.
Rails with Google Web Accelerator
According to Google Web Accelerator considered overzealous, there are some problems when Google Web Accelerator (GWA) starts prefetching all kinds of nasty stuff from your web application.
Refer to How to show Google's Web Accelerator the door in Rails for some code to prevent this from happening. Taking the unsafe GETs out of Rails introduces a new way of doing things with HTTP POST. Ruby on Rails Ticket #1269 is where people are working on another fix. More at I don't GET the problem.
Also read Google Web Accelerator: Hey, not so fast - an alert for web app designers.
This problem is discussed in section 16.9 (The Problem With GET Requests) of the Beta2 version of the Rails book.
