Python, django, and JavaScript
I’ve started developing with Python, and it’s quickly become my language of choice for all types of stuff. I’ve written a home automation socket server that exposes several serial RS-232 and RS-485 based home automation devices to the network. I’ve also done quite a bit of data manipulation / parsing with python, massaging data and sticking it into MySQL tables.
For web development, I’ve written one website using Python via Django, just a standard html based site, and I’ve got a plugin for a high-traffic site I’m currently working on with Django that mainly uses out-of-band http transmissions for AJAX. It’s really been more JavaScript programming than Python / Django.
