Nice! I learned Matlab to do nonlinear optimization of GPS data to solve for fault locking depths and slip rates, and then a year or two later learned Python to do run FEMs of thermochronology data (also to get fault slip rates) on Amazon's servers in parallel. (Matlab was not really up to that task.) None of that was to impress my advisor exactly, but it worked...
