As preparation for work interviews, I am taking a few weeks to brush up on popular programming languages. I'm a big fan of the code-it-yourself tutorial style of Codedeacademy, so I'll start with the languages they support.

For the first six entries in this series, I will be studying HTML/CSS, Javascript, jQuery, Python, Ruby and PHP (not necessarily in that order). Fair warning, these articles will be rough notes for my own future reference, rather than a reader-friendly tutorial. If you're looking to learn these languages, I'd highly recommend trying Codedeacademy yourself.
