what?
http://crappytools.com/pingurlspfft nah, that thing was out of annoyance.
I actually have quite a few things I have done that I am proud of, or at least was the moment it ran for the first time successfully.
I did what could be called a REDICULOUSLY LARGE web log processing project. web based. processed 1-3 gigs of logs per day, hourly. That was insane... and the sense of accomplishment was huge.
my first complete toolset for "other" ventures was pretty fulfilling as well.
My first full shopping cart.
my first bookmarking engine, that people actually used.
though i will say, not a single thing I have done when i was employed ranks up there.
