EKOPARTY CTF 2016 - FBI 100
The FBI category is something new that I personally have not seen on a CTF (though in all honesty I did have a rather long break). An FBI task usually is about a service (or server) with a known address in one of the darknet areas of Internet (think: TOR or...

#TIL  I always thought Norton Commander (1986) was the first double-pane+command-line file manager and it set the de facto standard for such file managers.

8 minute CGA demo, showing off 4-channel sound, bitplanes, Copper-bars, sprites, 256+ color plasma, 3D animations, and most importantly - bouncing text and 'greetz'. I think this trounces Microsoft Flight Simulator 1.0 as a litmus test for IBM Personal Computer compatibility.
