Resources for programmers and coders

I found these resources helpful while learning how to code:

1. When to use classes? This article explains concepts of class, when to create a class, inheritance, composition and aggregation. It provides a visual approach and goes step-by-step from easy to harder concepts.
2. C# Cheat Sheet: I made a cheat sheet when I was learning C#. It helped me remember common syntax, some important concepts and contains code snippets for a memory refresh.
3. Learn something new: This website has tons of resources ranging from concepts on algorithms to practicing languages such as C# .You are sure to find something new to learn or brush up your skills http://www.codeproject.com/script/Content/SiteMap.aspx
