Uniform access principle Explanation 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. Shoes wants to fit in. It will change the way it looks for each person’s computer. These screenshots were taken on my computer, but when you run them for yourself they will look just like your other programs.
Piano-ology Lesson Plan, Sitemap, Syllabus This page singles as a lesson plan, doubles as a study guide, triples as a music mastery checklist, and quadruples as a roadmap for navigating the depths of Piano-ology. Enjoy! Course Outline I. Pre-Music Preparation Here you will acquire the attitudes and knowledge that are so essential for becoming an expert learner. Real World Math Overview Our complete set of courses was originally arranged into majors and minors similar to what a student would find at a four-year undergraduate program. The programs below are not currently supported and are presented for student reference only. Please note that these majors and minors include currently unsupported legacy courses for which certificates are no longer available (what is a legacy course?) as well as currently-supported courses.
RubyIdioms - tokland - Ruby conventions and idioms - My personal repository for code and documentation This document shows some Ruby idioms, conventions and patterns, most of them accepted by the community, some of them personal.

Ruby GTK tutorial This is Ruby GTK tutorial. In this tutorial, you will learn the basics of GUI programming with GTK in Ruby language. The tutorial is suitable for beginners and intermediate programmers. Table of contents The GTK is a library for creating graphical user interfaces. 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. If you’re like me when I started, you’ll look at the overflowing abundance of programming information available and wonder why anyone would ever pay money for any of this stuff.

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.
Ian Knot, Ian's Fast Shoelace Knot I tie my shoelaces with my own "Ian Knot", the World's Fastest Shoelace Knot: Make a loop with both ends and simultaneously pull them through each other to form an almost instant knot. Don't confuse this with the very similar looking Two Loop Shoelace Knot - the technique is quite different and much faster. It's a truly revolutionary way to tie your shoelaces!
