Hi, using OS X 10.5.6 I installed fxruby using $sudo port install rb-fxruby As suggested in the book. It works, my hello world program worked correctly. Now, though, other code that I have written is broken, whenever I try to use any code that relies on a gem, it does not work. When I do $ruby -e "require 'rubygems'" in my code, i...
I'm not going to make this into a Rails vs Framework X discussion, there's plenty of those already. After seriously contemplating what framework I'm going to use for my next deployment, I decided it's very difficult to pass up the out of the box REST exposure Rails gives you for minimal work back. This is something that requires slightly...

A few years ago a friend of mine suggested I learn Ruby. I've since learned PHP and VB.NET but I never got around to Ruby. Where can I start with Ruby? Also, as a side note: What is Ruby primarily used for? How would you describe it in comparison to PHP? Python? VB? EDIT: How can I get it set up on Ubuntu 9.04? Vista or 7 Home Prem?...
I have csv file with 14 columns and I want to sort it in ruby by 6th column then by 2nd and then by 11th column. There is nice method .sort_by but it works only for two columns, doesn't it. And array_of_arrays.sort_by {|e| [e[2], e[0],e[1]],} doesn't work. so let's say in the sample below I want it to be sorted by 3rd,1st,2nd columns ...
I like the rake task structure and rake utilities.. I want to create a script that can do many things, and rake seems the logical choice. I want to know how can I make it look like a regular script: ./myscript.rb cake:bake as opposed to rake -f myscript.rb cake:bake any idea? Of course, rake must still be installed etc.. simply to ...
Argh! Everything has been totally fine, then all of a sudden I started getting this error when I was doing a 'rake db:migrate' And I get the same thing when I try to restart the rails server. rake aborted! undefined method 'form_for' for module `ActionView::Helpers::FormHelper' Confirmation that I'm running a current version: mm-MacBo...
Ok this worked: Student.transaction do if @student.test! y = @student.rooms.first book = Book.find(:first, :conditions => ["room_id = ?", y]) It's strange. I wanted to get the last record not first, yet it thought first was the last and worked. Not sure why. ...

I am using the ruby smpp library to send/receive SMS. Right now we are sending messages to two different servers, using the ruby-smpp library. One of them works perfectly, but the other one sends multiple DELIVRD confirmations for each messages. And by multiple I mean hundreds of confirmations per message in some cases. Does anyone know...

On runtime, my code often come into an undefined method error for the method mate. As far as I can figure, a Person somehow slips through the cracks sometime along the code's exucution, and manages not to have an allele assigned to it. Code (disclaimer, not the best formatted): class Allele attr_accessor :c1, :c2 def initialize(c1...
I've inherited a large pile of Ruby code that's, frankly, close to impossible to understand for a mortal like myself. It's actually Rspec unit test code, but the structure is "highly unusual" to put it nicely. What I'd like to be able to do is run the code, and have the following information logged somewhere: every method that gets i...

Then I call RtlMoveMemory in kernel32.dll to get a copy of the VS_FIXEDFILEINFO struct (see Microsoft documentation: http://msdn.mic...

First I attempted to do the following: jim:~/Desktop/spectest \ [git:master] → rake manifest (in /Users/jim/Desktop/spectest) Cleaning - pkg rm -rf pkg Building Manifest Man...
Within my Rails application, I'd like to generate requests that behave identically to "genuine" HTTP requests. For a somewhat contrived example, suppose I were creating a system that could batch incoming HTTP requests for later processing. The interface for it would be something like: Create a new batch resource via the usual CRUD met...
