I got all your latest books from Amazon. You are amazing I got the whole collection of the latest edditons. My favourite is the computer network book and Minix book . You are the BEST.
I remember buying his book, running MINIX off floppies on an IBM PC. oh, why didn't I ask on usenet of someone wanted to build a kernel with me based on MINIX :-D
Remember how Johan Stevenson (together with Jost) ported Minix to the Atari-ST. The first and only time I saw Johan struggle for days (maybe weeks) with 1 particular problem with the kernel implementation. Of course in the end he solved it.
I wonder what his thoughts that intel running his os as a backdoor in intel me. Maybe anyone knows any conference? I can't find any at least in youtube.
BSD might not have sold to AT&T. It was a project; albeit indirectly perhaps, of UC Berkeley and the California Board of Regents. Even then, they might have decided to fight AT&T since BSD had evolved quite separately from AT&T SysVR3 (or whatever version they were up to at that point in time).
Yeah, so he's rightly bashing AT&T, but the fact is that if he had chosen to put his own creation (Minix) under an OSS license from the beginning, Linux might never have taken off and it might be Minix instead of Linux that would be running all those smartphones and servers today. So he should be bashing himself too, even if just a little bit.
Olaf Klischat Why should he bash himself? MINIX was strictly designed as a teaching tool at a time when the latest UNIX systems could not be used for such purposes. Not placing MINIX under GPL or one of its compatible licenses was a virtue since it allowed the codebase to be kept under control so it could be useful to students. The problem for Tanenbaum was there wasnt an affordable UNIX system at the time. MINIX - being a low cost UNIX-like system attracted a lot of attention for its affordability which meant that people came to it wanting a full UNIX system, and got the ugly end of the stick when they realized that was never the purpose of MINIX, and Tanenbaum rejected a lot of suggestions for the sake of keeping the code simple and able to run on machines his students could afford. He actually refers to this in the Linux is obsolete debate when he says Linux will keep people who who BSD UNIX away from MINIX.
@@ScottThorpe Why? Because now he wants to make money with Minix. Clearly he made it open source too late and now in his own words "is trying to appeal to a niche market". He made a huge mistake not open sourcing Minix when he had a chance and he will die regretting it.
@@onufrybonekip3717 meanwhile MINIX runs inside of quite literally every Intel processor made in the last few years :P I don't think he regrets anything.
Minix wasn't nearly as locked down as other systems, as the source code was available for the price of a book. Of course it was way before the open source movement that he was operating in, and he's seen that BSD licences have a lot of good to them, which is why he changed his mind. I do think Linux is bloated, especially for things like smart TV's where you almost certainly don't need floppy disk and 40 different file systems support in the kernel itself. For android phones, sure, but they have gigs of RAM and a half dozen cores.
BSD was still under the AT&T license at the time Tanenbaum wrote MINIX (1987). "Until then, all versions of BSD incorporated proprietary AT&T Unix code and were, therefore, subject to an AT&T software license. Source code licenses had become very expensive and several outside parties had expressed interest in a separate release of the networking code, which had been developed entirely outside AT&T and would not be subject to the licensing requirement. This led to Networking Release 1 (Net/1), which was made available to non-licensees of AT&T code and was freely redistributable under the terms of the BSD license. It was released in June 1989." en.wikipedia.org/wiki/History_of_the_Berkeley_Software_Distribution#4.3BSD
The management ignored and gave away what was being done at Xerox PARC. They showed Apple (who were doing similar work, but not so ambitious), and Jobs said "What are you guys doing here, you could rule the world with this technology". Most of the Xerox PARC people left Xerox to go down the road to Apple to actually build products.
Speaking about bean counters: If Tanenbaum would have made his software free, Minix would have taken the world by storm instead of Linux. The software architecture of Minix is superior to that of the early linux distros. At the time I could not comprehend, that he did not put minix under a free license. It was just unbelievable.
Tanenbaum wanted to make MINIX free software, but Prentice-Hall refused to allow it. It isn't fair to say that this was done for his own profit; it was done because the publisher refused to have it any other way.
@@kovoc1 He could have marketed his book without the software and published the software independently. It is normal that book companies protect their IP.
@@michaelkaercher The source code of MINIX is integral to how 'Operating Systems: Design and Implementation' is structured; I have doubts as to if Prentice-Hall would have been willing to allow Tanenbaum to retain his copyright on it. Regardless, the idea of Tanenbaum and VU Amsterdam being able to supply the massive demand that MINIX elicited seems unlikely. I suppose that he could have published MINIX on USENET, but that would not have succeeded in getting MINIX in the hands of everyone who wanted it. I think that Tanenbaum made the right choice--and that this choice was not motivated by profit. His goal was to get MINIX in the hands of as many students as possible, and I think he accomplished that goal in spite of the circumstances.
I understand his thinking but this is not like if this wouldn't be there there wouldn't be that kind of thing. It would just be something else. There's plenty of clever ppl
Andrew always makes me laugh with his pointless remarks. If there were no Minix or Linux, there would be some other open-source system around. Most likely the army of Linux programmers would join the GNU/Hurd project, or something similar...
Dejan Lekic The problem was that GNU had been in development for about 8 years and Hurd still did not show any signs of materialising (RMS spent three years thinking that Mach could be used and Hurd did not boot until 1994 -by which Linux was starting to become a significant commercial force) and there was the AT&T lawsuit with FreeBSD. Linux happened to be at the right place at the right time and rightfully won where other OS's had failed.
It just sounds too good to me to not play a much larger role in the operating system market. If the kernel is also written in Rust, then it should probably be the most stable little technical masterpiece, which unfortunately has played far too small a role so far.

Hey man, you might be at the wrong adres to post your comment. I believe you might have the MINIX 3 operating system and the mini computer mixed up. They're both veeeeeery different things :)
I Say MINIX, because You P1Gs Understand It to Be Secure. So, I have to Talk your Language for you To Understand. Believe it Or Not, Kesaria Kernel was about Security Not Speed. Intel Makes 3 to 5 GHz CPU's. CPU's are Fast Enough. We Need to Make Security, Was My Idea. ALL, Operating Systems Want to Be Secure. They don't do it at the Cost of Performance.

He explains why microkernel is better. Lack of this architecture is a severe weakness in Linux.

Wow. If Robert hadn't of heard about interrupt 15, then I'd probably be using FreeBSD. Cool.
hey people is there is a chance to convert monolithic kernel to micro kernel?
The man is a god.
No, just a member of a tribe that claim to be chosen by their god.
why did he not use BSD for teaching instead of writing his own (Minix) ?
He learnt so much from writing his own OS. Since he put every line of code in it himself, he can teach it the best.

Because BSD are monolithic kernels.
There was no freely available BSD until 1992 (386BSD, the basis of all current BSDs today).
True boss.
Wow! Just, wow!

What was the "something Xerox did"?
Xerox mostly ignored graphical interfaces with icons, windows, and mice, even when they had it right in front of them. See Xerox Alto.
The management ignored and gave away what was being done at Xerox PARC. They showed Apple (who were doing similar work, but not so ambitious), and Jobs said "What are you guys doing here, you could rule the world with this technology". Most of the Xerox PARC people left Xerox to go down the road to Apple to actually build products.

Nope, BSD was licensed to only some US universities. It wasn't freely available.
