Small shout out for Sir Maurice Wilkes, who was involved in some of the earliest stored program concept computers back in the late 40s (designed and built EDSAC in 48/49, and the inventor of microprogramming in the early 50s. Worked in the Computer Lab in Cambridge for years, spent some time in the US, and returned to the lab in the early 2000's. Was still a feature in the labs until not long before his death in 2010, at the grand old age of 97. Would have been around the 60 odd year mark at that stage. I can't speak to how much he was working at that stage, but still a very impressive career and a very impressive individual.

+1 for tig, which is an awesome tool. I tend towards it mostly for walking through commit history, but it also works very nicely for staging files selectively (and is very good for selecting individual hunks in a larger changeset).
