After Hours Programming
Grades 8 – 16. The primary purpose of this website is not just to educate you about a certain language or simply programming. The fact of the matter is that not all web development is programming. Sure, the markup language and the server side processes ultimately render the page for the user to see, but think about the massive websites like,, and Do you think that they just have programmers and maybe a few graphic designers? Absolutely not! They can have hundreds of employees working on the website that haven’t ever written a piece of code. This website is devoted to making you a more well-rounded developer by understanding what these other guys do and, of course, a whole lot of other important coding stuff. Tutorials topics include: HTML, CSS, JavaScript, PHP ColdFusion, Python, SQL, Graphic Design, Information Architecture, Usability, and SEO.

An online code editor that lets people collaborate in real-time. It works in your web browser so no installation is needed. Features include text editor, chat, document history, and syntax highlighting for programming languages. Great for collaborative coding because email and instant messaging do not work well for sharing code. They don't preserve whitespace, the fonts aren't monospaced, the spell check gets in the way, etc. In addition, they don't have a good editor, they're only good for copy and paste. Collabedit has what you need - a good editor, syntax highlighting, real-time collaboration, chat and versioning.

Glossary of Coding Terms for Beginners
Grades K – 12+. Coding tells the computer what to do using a language it understands. There are dozens of different programming languages, but they all share a single foundation. Each language follows a specific set of rules that determines how code should be written, and then uses back-end software to translate it into binary (the computer’s native language). Even if you don’t intend to take on programming yourself, encouraging children to code will be easier if you can speak the same language as them. This glossary is a quick-reference tool to help kids work through their initial coding questions and concerns.
