In 2005 I was a sysadmin at the IceCube Neutrino Observatory headquarters in Madison, Wisconsin. Biggest project I worked on was porting RS 485 serial drivers from a legacy unix system to Linux 2.6 and setting up the HP rack servers which we then shipped down to the pole from New Zealand on a C-130 Hercules. Also, I built a data visualization system in python+django which ran over a 1km-long DSL network between the drilling site and the south pole base. Never got to down there myself (my FTE boss did), but it was a fun project for a student and looks good on the resume and all. Did I mention SSH connections over satellite to Antarctica are pretty slow?
