Happy memories of the days when AT Computing was still housed on the premise of Radboud University and teachings were done by HJT himself. The PDP and a VT100 was just standing there next to him in one of the classrooms.
I used XENIX on the first programming course I went on. It ran on a 386 with 2mb RAM and a 200mb disc. It supported 14 green screen serial terms. When we were all using vi it would slow down a little. This was in the early 90's.
For the part around 4:00 about Moore's Law and our computers 45 years later being a billion times faster, if the speed doubles every 2 years, why isn't it 2 ^ 22.5 instead of 2 ^ 30? Why does he divide 45 by 1.5 first?
45:45 Because while MINIX may have been slightly easier to get hold of than the Lions Book, it still had its own restrictions, which is why Linus decided to create his own.
Nou ik zou die PDP11/45 van meneer Thomassen best willen adopteren en draaiend maken. Hier staan een hele reeks PDP8 en PDP11 machines welke gewoon in werkende staat zijn. (ja dat heeft wel de nodige restauratie uren gekost, want na 50 jaar werkt dat spul niet meer) Maar het materiaal is prima te restaureren en oer degelijk. Geert Rolf (genoemd in deze opname) heeft recent nog Unix V7 op zijn PDP11/55 laten draaien. ( th-cam.com/video/_ya8ztcpDRw/w-d-xo.html ) Een prachtige indrukwekkende machine!
18:27 But even at 800cpi, a 2400-foot tape reel could fit enough that you only needed maybe 4 tapes to back up the whole disk en.wikipedia.org/wiki/9_track_tape .
Thank you for this informative talk. It is Nov 2023 now but information like this is never too old.

Nice Unix beard!
Yeah, this guy is legit. :D
Here's a nickel kid, buy a new computer
unix beard lol
Interesting talk. Thank you.
Brilliant lecture. Much appreciated. You've lived your lecture topic.
Glad it was helpful!

Fascinating talk.
Superb lecture. Thanks
dd's name is an homage to the DD statement in IBM JCL.
Simply incredible! Many thanks for all those details.
17:41 Interesting he mentions the regular 9-track tape reels, but overlooks the DECtape units (those prominent pairs of white rings).
This was Bloody interesting!
bloody paper tapes
I was thinking this guy would blend right in in Australia with his use of the word bloody. Bloody brilliant talk!
29:45 The ones missing from my Xubuntu system: dfw, opr, pfe, prof, rew, tp, tss, typo,. (cdb, db and prof subsumed by other programs.)
The talk is more "From UNIX 1969 to UNIX 1985", isn't it?
38:47 Actually nowadays all the functionality of creat(2) has been subsumed into open(2) with the right flag settings.
For the part around 4:00 about Moore's Law and our computers 45 years later being a billion times faster, if the speed doubles every 2 years, why isn't it 2 ^ 22.5 instead of 2 ^ 30? Why does he divide 45 by 1.5 first?
I believe Moore law doubled the speed every 18 month (1.5 years, hence the divide by 1.5)
Unix remains the most efficient timesharing/multiprocessing operating system ever.
very interesting !
Good stuff
Nice talk...

"Zeroes AND ones? Luxury!.Back then, we had to beat zeroes into ones wi' flat rocks". :-)*
Mooi verhaal!
i always thought it was pronounced zee-nix, not ksee-nix ?
In Dutch, "X" = "ks".
I never heard of that dude.
That's nothing compared to how many people have never heard of you.

Hurry please okay
Imagine the scene... Bill gates selling Unix in road side stall :)
