This is just an annual reminder that DShield, the engine behind the SANS Internet Storm Center, was originally coded over the Thanksgiving weekend in 2000 and made life shortly after. Below is an early screenshot (not the earliest one, but the earliest one I am not too embarrassed to post :) ).  The domain was registered a few months before I started coding the site (July 7th, so probably July 4th weekend), but I didn't get around to coding it before. The first "submission agent" was a one-liner shell script grepping logs from Syslog and piping them to sendmail to submit them :). There are not a lot of projects that have survived this long, and well, some of the early code (and certainly design decisions) may still live on today.
