Old Unix hack turned landscape photographer with a Mac these days - which I love after years banging my head against brick walls with MS Windows. My StackOverflow heroes are, in no particular order: - for all-round technical prowess and friendly advice - for tirelessly correcting my amateurish attempts with GNU Parallel - for knowing everything about awk and tirelessly correcting my amateurish attempts at awk - for everything bash, awk and sed - for the ability to turn any problem, and any number of pages of Perl into a single, unintellgible-to-humans, concise statement 3-7 lines long, only involving split() , join() , map() and a bunch of mad symbols all of which produces a miles better solution and runs in 1/100th of the time of anything I could ever hope to write - or read! ©
