  1. TIL why jpeg vs jpg

    In DOS systems, a filename extension was a different part of the name stored in a different field that can only be 3 characters. You still see this legacy today in Microsoft's .NET software, where most system calls that use the word 'filename' in their name don't really mean the whole filename. They mean just the part without the extension.

  2. TIL the first webcam

    The Trojan Room coffee pot was a coffee machine located in the Computer Laboratory of the University of Cambridge, England. Created in 1991 by Quentin Stafford-Fraser and Paul Jardetzky, it was migrated from their laboratory network to the web in 1993 becoming the world's first webcam.

  7. TIL about why Node was invented

  8. TIL a junior dev who programmed a World Heroes Genesis by himself

    Yeah, World Heroes (even the original) wasn't anything to write home about. I had to squeeze 82M into a 16M cartridge. The source code was in assembly with absolutely no documentation. There were no testers. There was no one to help me port the artwork.
