I work on projects that mix computing and physics - I have a pile of experience as a software engineer, but my education, way back in the day, was as an astronomer. And it was research in astronomy that first took me to Chile, where I now live. So I telecommute from Santiago, working with companies in the USA and UK. Currently I'm part of a small team developing software related to geophysics - I guess you could call it a consultancy, but really we're just people that understand what you need and then - importantly! - make it.
Some of my favourite answers:
- Exploring constraint programming
- Converting recursion to iteration with Python generators
- Tiling pipes
- Correlated random numbers
- Matching integer ranges with regexps
In every case I learnt something new, which is what's so good about this site :)
