Here is my (very simple) version of 99 Bottles of Beer on the Wall in Ruby. I the only fancy thing I am doing is “while”. I don’t like the fact that the song is duplicated to handle one bottle, so I will eventually change that. I have a couple of ideas, [...]

May 15th, 2008 No Comments
I’ve noticed that Twitter has been going down quite a bit lately. I have heard that the Twitter people are looking into switching from Ruby on Rails to something else.

UC Berkeley Ruby on Rails 1-Day Course
May 10th, 2008 1 Comment
I found a one day Ruby on Rails course from UC Berkeley on YouTube. I haven’t watched the videos yet, but hopefully they will help improve my understanding of Ruby and Rails. With any luck, they won’t be 1 hour rickrolls.

Ruby Course – Lesson 1
May 6th, 2008 1 Comment

Modulus (Modulo) in Ruby
May 5th, 2008 3 Comments
I found the modulus operator in Ruby to be quite different than Java. I think it worked the same way in Python, but I can’t remember.
I found a relatively easy way to figure this out for negative numbers:
When the second operand is positive:-12 % 4 = 0-11 % 4 = 1-10 % 4 = 2-9 [...]

Rails
March 17th, 2008 No Comments
Today I went through the Developing Rails Applications on Mac OS X Leopard tutorial. The tutorial from Apple was much easier to digest than some of the other ones out there. Yikes. I’m not afraid of terminal, but I started to get extremely confused when many of the tutorials I found were [...]
