I know this is old, but if you look at the code in the original DOS, they stole a lot including loadable drivers. There is even a residual variable instance counter as a hook for multi-user.

I think Unix eventually got a GUI but back in the early days it was all text-based

@tylerdean980 Год назад

Home computers didn’t get a gui until the 80’s really, this is a decade older. Just open a Linux terminal and you have an idea of what it was like. Of course, in the very beginning they weren’t using terminals either, it was punch cards

That tree is fantastic!

@GodEmperorSuperStar Год назад

3:00 Eight Edition UNIX (UNIX v8) is in the wrong place on that tree. Rob Pike wrote that the history of UNIX leaves out Bell Labs research UNIX after version 7 as if it never happened. Did you know that Dennis Ritchie wrote symbolic links for UNIX v8 and his code was added to BSD? Did you know that there was a Datakit based network called XUNET that was contemporaneous with the ARPANET and XUNET connected Bell Labs with the University of California at Berkeley (UCB) where BSD came from?

Not only is the mach kernel of Nextstep, Openstep, and macOS, obviously, since macOS version 10 and following came from Nextstep, but macOS IS a Unix operating system, and has been such since certified by The Open Group, who owns the Unix trademark, as far back as 2008 or 2011.

Mac ks , since 10.5, is unix, ie at has been sertified as such by the open group thatare thevuwners of the unix trademark. So osx is more than derived from unix, it 'is Unix, linux however is not. But both oses are posix compliant. And yes indid react to the osx comment before warhing thus entire exelent video my bad)

@rayrai982 4 месяца назад

You eventually explained why whole microsoft windows os crashes once it's file explorer crashes. It's because of dos(disc operating system), microsoft than used msdos(microsoft disk operating system). Whole os orient around file exploration (i mean windows file explorer). While on unix or linux even if you don't have a file explorer like thunar or dolphin your os still works.

MacOS is Unix at core and this is clear when working with a terminal app in Mac. iOS and iPadOS are also based on Darwin which is Apple's unix core. I think MaC is the best OS for those who can't decide between Windows and Linux. It has the best of the both worlds. And Homebrew is a great package manager for Mac.

@HaroldSchranz 11 месяцев назад

Cute summary ... but I guess I've used most of the major (real) UNIXes(and Linuxes) and all the other real OSes (primarily TOPS-10, VMS) ... and quite a few (awful) OSes ... (including Windows/DOS, NOS, KRONOS,...) ... so I have a pretty good overview. Without DEC, we would probably not have UNIX.

So how secure is Unix

@TeXplaiNIT 2 года назад

I’ve heard that it’s more secure than windows due to popularity or rather lack thereof

@tylerdean980 2 года назад

Unix is not available in modern form, best to use Linux or BSD. But it is much more secure than windows because it uses file permissions and has privilege levels that are more granular than windows. And it actually requires a password to install things by default, that alone is what causes 80% of windows infections.

@unwoke1652 Год назад

All online financial transactions are done in BSD due to that OS being much more secure.

Windows is not inspired by UNIX, because Dave Cutler, the father of Windows, came from DEC and VAX / VMS, and is a notorious UNIX hater (and proud of it). VMS is nothing like UNIX at all. There is only one open source, freeware, canonical UNIX operating system directly descended from the original UNIX: illumos, being a fork of OpenSolaris, being an open source version of what was to become Solaris 11, being a direct descendent of AT&T System V Release 4.0 UNIX.

I started my engineering career with Unix. First on Silicon Graphics Indigo 2s, the Sun, then HPs. Then, one company had switched over to MS Windows PCs when I started there and I had no idea how to use a Windows PC. I had had 7 years engineering experience, been to university, couldn't use a Windows PC. 😆 I hate MS Windows to this day; you seem to be always fighting it.

And, this man's chart has FreeBSD thereon, but legally it is not Unix, because it did not pay the $100 000 certification fee to The Open Group. This presenter needs to do a bit more careful research before touting what he knows. He's only partially correct on certain points.

Unix still matters: iOS and MacOS are Unix (BSD Unix). Solaris and other operating systems used in the scientific community are Unix. Video title is correct.

@MrEnyecz 10 месяцев назад

Unix does NOT matter today. Unix went down with the Unix wars and the successor of it is Linux. Linux is the ruling operating system (I know it's not one operating system, but a family based on the same kernel) everywhere, except personal computers, where the ruling is Windows and probably MacOS. There is no Unix, just in history. But in history, there are other important systems like CP/M, which is the system that inspired the DOS->Windows line.

@krunkle5136 8 месяцев назад

Mac OS is Unix based and is even POSIX compliant. Unix used to matter more, but its ideas of simplicity, worse is better, and modularity prevail. It is the world's most successful computer virus.

@tedisrozenfelds7630 6 месяцев назад

But Macintosh is another winner who arose from the Unix wars who dominates personal computer market. And as the author of video showed - actually Bill Gates (thus Windows in a way) also was one of the Unix wars participants, but after trying its stand in Unix like systems decided to create a completely different OS architecture. But we could say that that is also an outcome of Unix wars. So the winners of the Unix wars are all the modern OS giants - Linux, Macintosh and Windows
