The future of shoulda
in Ruby added by admin, on 18/6/2010 framework ruby on rails shoulda testing
Shoulda has long been one of our most useful and popular open source projects, and it continues to serve us well as we use it daily. However, there have been some changes over the past year in the way that we use Shoulda, and these changes have led to some decisions about its future. In our post about the Rails 3 roadmap, we briefly covered the changes we made in Shoulda 2.11 as well as our intentions for Shoulda 3. However, we wanted to go over these changes in depth and explain some of our motivation.

in Ruby added by admin, on 12/6/2010 apache2 news passenger

We were the first to implement a working Ruby web app deployment solution that integrates seamlessly in the web server, and all the features that we’ve developed over time – smart spawning and memory reduction, upload buffering, Nginx support, etc – have served us for a long time.

Rake Tasks 101
in Ruby added by admin, on 10/6/2010 framework oo programming rake ruby on rails
I’ve been working with Rake quite a bit on my current project so I thought I’d share some beginner tips. Before I go into Rake, what is it? Rake is a Ruby-based build program. Ruby on Rails uses Rake quite a bit in it’s process. If you’ve worked on a Rails project you’ll used one, some or all of the following: rake db:create, rake gems:unpack, rake db:migrate, and rake test. Now that’s not all of Rail’s Rake tasks, just some common ones.

CSS Star Rating System
in CSS added by admin, on 12/5/2008 examples intermediate style
Recently I had to create a Star Rating system for a client so I thought I'd share with you the techniques I used to accomplish this. If you are not familiar with a Star Rating System, it's simply a method of voting using (usually) 5 stars in a row, which will change colour as you hover over them indicating the level at which to rate something.

A Lightweight Approach to Aspect-Oriented Programming in Python
in Python added by admin, on 21/4/2008 aspect-oriented intermediate
aspects.py library provides means to intercept function calls. Functions and methods (also in Python standard library and third party code) can be wrapped so that when they are called, the wrap is invoked first. Depending on the wrap, the execution of the original function can be omitted, or the function can be called arbitrarily many times. Wraps are able to modify the arguments and the return value of the original function. In the terminology of aspect-oriented programming, the library allows applying advices (wraps) to call join points of methods and functions in around fashion.

Learning Python Programming Language Through Video Lectures
in Python added by admin, on 8/3/2008 beginner tutorials video lectures
One of the upcoming projects I am doing (I will reveal it in one of the next blog post) is going to be written entirely in Python. I have a good understanding of Python but, same as I had with JavaScript, I have little experience doing projects from the ground up in it. Before diving into the project I decided to take a look at a few Python video lectures to learn language idioms and features which I might have not heard of.

Adding Type Checking to Ruby
in Ruby added by admin, on 6/2/2008 intermediate type
What’s the first thing you think of when you consider the Ruby Language? Dynamic types, right? Ruby is famous (infamous?) for its extremely flexible type system, and as a so-called “scripting language”, the core of this mechanism is a lack of type checking. This feature allows for some very concise expressions and a great deal of flexibility, but sometimes makes your code quite a bit harder to understand.

Python as Config Language -- Forget XML and INI files
in Python added by admin, on 12/1/2008 configuration-file
A programming language has all the advantages as a language for encoding parameters. I see why it's rare -- too many programmers have spent too much time with MS's abominable INI files and think it's "normal".
