Why is Ruby, and Ruby on Rails (1.8.6 One Click Installer, local database) so ruddy slow on Windows? ruby script/server - 30 seconds rake test - 45 seconds etc. Yet, when I pop over to a much slower linux box, it's virtually instantaneous. I've checked everything - no significant CPU processes running, no network issues... and so on...

A user posted a very nice list of problems from Beginner to advanced that should help you get to know a language. One of the problems is to create a phone book, with random phone numbers and random people on the phone book, and a us...

I have a RoR project on my Windows 7 PC. I want to create some Ruby code that I can execute from the cmd.exe command line that manipulates the development database (via database.yml) of the project.

For various reasons I can't use ActiveRecord in this situation. (Note: The above code runs fine on my shared host. A...
I've just upgraded from MRI-1.8.7 to MRI-1.9.1 and heard about this lighthouse ticket which indicates that Ruby 1.9.1 and Rails 2.3.x won't play nicely together when a user enters any kind of non-ASCII standard character (i.e. å é Ã Ø å ल) unless rails is patched. My problem is that I CAN'T reproduce the bug. I've tried everything. I'...

What type of language it is and is there a need to le...

I have a couple of views I'd like to have appear on every view that is rendered, but short of duplicating code or breaking the specifications, I can't seem to find a way to accomplish this.

I am starting on a number of big PHP projects which I need Bug Tracking, Wiki and Subversion integration capabilities for.

I am looking to set up a Redmine server on a Windows virtual machine on my local workstation. (Background in this related question.) I have zero knowledge of Ruby nor Rails, and while Redmine may be the opportunity to dip into those platforms somewhat, my first goal is to get it running as quickly and easily as possible. For that, I am...

Trying to Google around for an a Rails plugin that will allow for throttling the amount of requests a particular resource gets consumed. Django's Piston has some open source code for this.
