  &quot;so how can CD&apos;s continue to work afterr they&apos;ve been scratched?&quot;<br><br>me: oh boy, you&apos;re in for a treat. So it was late 50&apos;s and there was this guy called Richard Hamming

  &quot;Checksum from hell&quot; is the sickest math-rock band name out there

  Good old Évariste Galois. Came up with all his amazing mathematical theories by the age of 20, at which point he got himself killed in a duel.

  DVDisaster is a piece of software that auguments empty DVD-iso space with error correction codes. I tested it working by intentionally scratching a disk, and it saved me quite a few times later. Awesome extra protection for backup disks.

  Main thing I learnt from this is the definition of &quot;syndrome&quot; lol

  When starting my degree in CS, I got interested in QR codes and their uses of Reed Solomon Encoding. It was the first time I went &quot;Nope&quot; so hard. This bring back nightmares.

  How about another collaboration with 3b1b? He&apos;s been covering error correction a lot lately, and it&apos;d be cool for him to feature again.

  This seriously helps me, even after 35 years I have been arguing with computers.<br>&quot;Checksum from Hell&quot; :-)

  In the 60&apos;s MIT was already deeply involved in computer tech, as was Berkeley. I think CalTech was only a couple of years behind those two as well. And Silicon Valley (although not known by that name yet) was already becoming a distinct high-tech area. Remember one of SV&apos;s most legendary companies, Fairchild Semiconductor, was already founded in 1957. So no, certainly not everybody was at Bell Labs anymore by then.
