Uniform access principle Explanation[edit] The problem being addressed by Meyer involves the maintenance of large software projects or software libraries. Sometimes when developing or maintaining software it is necessary, after much code is in place, to change a class or object in a way that transforms what was simply an attribute access into a method call. Shoes! The easiest little GUI toolkit, for Ruby. In case you’ve just arrived: Shoes is a graphics toolkit for writing colorful apps using the Ruby programming language. Ruby is built into Shoes.

How you can learn to program: web development resources As promised many moons ago, I’ll sum up what courses, books, and websites have been most helpful to me, as well as some that I’ve heard great things about within the web development community. A quick note on costs: I learned how to program on a budget, so I can certainly empathize with people who don’t want to break the bank without proof that they can get a job doing this stuff when they’re done studying. Most of the resources I list here are relatively cheap and require only a one-time investment. However, there are a few subscription-based resources that can start to add up if you enroll for a few months.

Understanding Ruby Singleton Classes - Devalot If you learned object oriented programming from one of the more static languages such as C++ or Java, the dynamic nature of Ruby may seem magical and elusive. After running into the syntax dedicated to meta-programming you may have been left scratching your head or at least wondering what’s happening behind the scenes. Singleton classes, not to be confused with the singleton design pattern, can easily be placed into this head scratching category.

late-binding semantics comparison by Antoine Beugnard Abstract. We observe the various interpretations of overriding and overloading in object oriented languages. With the description of an intend, represented as the following UML diagram, we have "naively" implemented in 15 different languages the same piece of code... and obtenained 11 different results. The question is: How will this model behave? A new language signature with Perfect.
