Started playing around with HTML and CSS when I was about 8. Tried JavaScript but it never stuck. Started to learn a bit of Python when I was about 13 and enjoyed it, but never applied it to anything other than some maths. Used some basic ActionScript in Flash animations. Wrote some simple VBA in Excel. Learnt Matlab during my Engineering degree. Now I use Mathematica for my PhD work, Python for fun and useful bits of software for myself, and the occasional bit of PHP and whatever else I need at the time to get something working.
