  1. 2:14 Is that Spanish for “/dev/null”?

  2. 4:52 “1.44” ... Q: is that megabytes or mebibytes? A: Neither.

  3. 8:35 Spoiler alert ... . . . . . Keep an eye on the colour of the Mac’s desktop background.

  4. 10:39 Also my experience with CD-RW discs is they were highly unreliable. I used them for a while to transport files between my office and a client’s place (in the days before USB sticks), but I never depended on them for backups. CD-R was the way to go for those.

  5. 11:58 Unfortunately, CD-Text only seems to have very limited character-set support. Unicode? Hahahahaha!!!

  6. 1:44 Blame your OS for the misrepresentation. My OS uses the correct units.

  7. 13:03 Apple were quite keen on PhotoCD. They built support for it into QuickTime and MacOS, so that when you inserted a PhotoCD disc into the drive, it would automount and the images would appear as files (in a range of resolutions) that you could just drag and drop to your hard drive. I still have the CDs that came bundled with my 1993-vintage Mac Centris 650, one of which is the Kodak PhotoCD sampler disc. But yes, I remember asking a Kodak guy at the time why they didn’t just adopt JPEG compression (which was the hot new thing back then). Their format allowed for a range of resolutions to be encoded into the same file, but that didn’t seem to be important at the time, and it seems even less important now.

  8. 15:09 There were some vendors that pushed the envelope even further, with 90-minute discs, at least. But the reliability fell off at that point, so things finally stabilized back at 80 minutes.

  9. 11:19 The aftermarket CD player that I fitted in my previous car would not play discs that had been burned at faster than 8×.

  10. 13:50 Aaah ... “Enhanced CD” ... would that explain it? Prior to that point, CD-ROMs stored their data in what looked to an audio CD player as track 1. There would be a warning label somewhere telling you not to put the disc in an audio player. Or there might be discs with data in track 1 and regular audio in the remaining tracks, where the warning was just not to play track 1. I tried once, and it sounded like a chainsaw was cutting through my speakers ...

  11. 13:34 I think that is an inevitable stage in the evolution of every large corporation. For example, I would say Microsoft is entering that stage now.

  12. Did anybody else buy those CD-R blanks that were made to look like vinyl records? I think they came initially from Verbatim, then a few other vendors copied the idea. You can’t get them any more.

  13. 3:25 “CDs-ROM” -- touché! Great for storing your multi-medium datum base!

  15. 4:31 Commonly (and unfortunately) abbreviated to just “ISO”. Hence “.iso” as the extension for CD image files using this filesystem format. (Sigh...)

  16. 1:06 It is not a silly word! It just takes practice to say: “Mebibyte! Bemibyte! Mebebibyte!” Oh, bugger ...

  17. 15:26 I think the longevity is very highly dependent on the brand. I soon learned to stick to good brands, like Sony, Verbatim and TDK.
