We use PostgreSQL mainly but have a MySQL db and the aforementioned MS Access db. I guess I should mention that the MS Access is just a front end to a MySQL db via a plugin.

We have a mix of php and python for websites, and a mix of python and c for our internal libraries.

I've recently been working on smoothing out our (my) workflow here....been using virtualenv, pip, git via Github, and fabric.

I actually get a chance to use the main 3 OS's. Our servers are all Linux, I do local development on the mac, and I use windows as there is a small MS Access program I maintain for a customer.

At work I alternate between sitting and standing with the following setup pic.twitter.com/bGJqSQRmOW All of my 'work' is done from my mac while standing...if I need to sit I just switch to my windoze (hehe) machine and startup up my vnc to continue working where I was.
