    Then what specific OS?

    network power features like slirp and masquerading

    How were either of these unique to Linux?

    free developer tools for many languages.

    So no different than BSD?

      BSD is not a commercial OS and isn't in competition with Linux.

      Linux brought those things to the consumer desktop. In the 2000's it not only continued to gain functionality but actually gained polish. Today, Linux is at least as polished and pretty as Windows or OSX.

      The only people still using BSD (and honestly most of the "hardcore" distributions of Linux) are people who appreciate difficulty for it's own sake. Unlike windows and OSX you trade no functionality for the polished experience. You simply fall back to manual effort when you need more flexibility than the polished tools provide and most of the time the polished tools break none of it.

      If you have trouble with rpmbuild; yum -y local vs make; make install and therefore choose the old way and break package management thus finding yourself in a dependency hell a year later... that's because you are ignorant, perhaps willfully, and your outdated and unpolished system that gives you no added functionality is what you deserve.

      For myself... I used desktop linux in 98 and have used linux in the server rack since that time. It has taken many forms and flavors for me including LFS for awhile. That was great for learning how everything works under the hood. If you are using anything but a modern user friendly linux on even a 5 yr old desktop and spending more than 2-4 hours configuring and customizing the OS itself on setup (less than windows or OS X) then I have to question your life choices. Unless are learning, why waste time manually doing things the hard way when you can point and click your way to a solid and well configured launch platform for working on the new thing you are learning now? If there is some detail that matters which you can't point and click you way to, why not help improve the polish so you can move on? The point really extends to experienced users of windows and OS X (by which I really mean the latest and greatest edition of OS X in the same way windows is nothing but the latest and greatest NT) as well.

      The OS wars are over. You could make a very good argument that Linux won since it is by far the most heavily deployed OS overall. But really it's more that the war itself become obsolete because open software stacks won. Even if you are using windows outside of certain niche environments most of the software you are using is cross platform OSS and most of your experience takes place in the browser or at least the network. It really makes very little difference what OS you use because no OS actually won and therefore everything has to work everywhere.

      I switched from a linux desktop back to windows for years because working on third party systems constantly meant needing windows only apps and because windows got me from scratch to a working platform more quickly. Meanwhile I continued using linux as my first choice for... everything else. Now I've switched back to find Linux Mint actually provides a smoother, easier, and prettier experience these days on my brand new high end laptop supporting all the recently released hardware out of the box. It was so quick and easy I actually did spent a little time customizing frivolous things like window behavior, desktop effects, and widgets. I'm not sure I want any new innovation on my desktop. Just keep pace and let things grow more stable. Maybe fix the odd clipboard behavior and inconsistency? Middle click paste is a cool concept but not worth the hassle. Finally fix the quirks of kmixer?

      The only thing left was support for the vsphere client. The virtual F5 in my lab ties me to this and the lack of functionality in the web equivalent in newer versions also hampers me here requiring me to virtualize windows. The solution is I'll simply remove both vmware and F5 from my lab. Many enterprises still have these things but that isn't the direction of the future. The future is about the open equivalents that have caught up now on the core functionality you need from these things are easily deployed on any cloud stack giving greater flexibility and automatabil

        If we are talking about the early 90's there was Windows NT 3.1 and OS/2 as well as BSD, SCO Unix and Xenix. Plus there were still Unixes available for several higher end work stations like Sun and Silicon Graphics.

        In technical terms the Windows NT kernel compares very favourably with Linux which was pretty agricultural by the standards of the times. Taking just the example of the thread support, Linux threads were a fiasco for many years.

        Also, who the shit wants to run HP-SUX? I got paid to figure out how to set up IPSEC on it once, holy crap. The documentation was literally backwards.

        Didn't Linux do a lot of those fancy networking tricks before most commercial Unixes? Stuff like packet mangling and IP masquerading? And the free dev tools may have been available for other platforms, but there's a big difference. Most of the time, the official compiler would shit all over gcc. I worked for a company that had the sunspro compiler suite, and of course I got gcc, and anything that would build with sun's compiler would just crap all over a gcc build. Since a lot of the early work on gcc aimed at x86, you didn't get as much benefit from using some vendor's compiler on a PC Unix as you did on those more expensive platforms. So yeah, I had the GNU suite on my Sun machines, but the PC running Linux really changed the industry.

        To be fair, BSD had new stuff, too. But the community was less friendly, the documentation less penetrable (use the source? I wasn't there yet) and the license apparently attracted less contributions.

    There is so much innovation these days that it has transcended the separation-by-OS that used to handily signal where and what kind of changes you could expect. As an example, if you're looking for an experimental graphical terminal emulator [acko.net] it turns out you can use it in Windows and OS X, but not in Linux. But the point is, it's not available on one OS in particular and it's even a virtue now to be cross-platform. There's so much new tech out there and it all happens on a huge variety of platforms. So trying out new tech is just a matter of focusing (for example: system software, graphics software, hardware support, kernel-level new stuff, software in embedded systems, hardware sensors, etc.) and then deciding what the required resources are to dive in on that specific level. What OS or OSes would be best, what packages should you install, and so on.

    Going back to your examples, 3D/VR desktop work has been going on since the 80s at least, and AI before that, and "drastically better performance" has always been on peoples' minds. The GUI mashups even ring a bell, though everything is so scriptable these days that anyone who's doing a GUI mashup would probably be less frustrated just typing it into a reusable script. These aren't new topics, they change over time incrementally, and the only advice I can give is to make sure you are _really_ looking at the high-end tech that you think you are. If you are frustrated with a slow system, did it cost less than $10K? Because that's commodity-level pricing. If you are frustrated with the 3D effects you just enabled on your desktop, did you really research the state of the art? And so on.

    Also, just to nitpick--you say Ubuntu is dumbed-down in "default configuration" but Windows and OS X are dumbed down by default too, aren't they? That's why you have package managers, Ninite, the App Store, etc. Restore your purchases or download a set of things and you're out of the dumbzone.

      Yeah, I don't know why it has been such slow going... back in the naughties I was working with distributed applications... We'd be setting up MOSIX clusters with transparent process migration (it's often faster to migrate the process to the data rather than get the data to the process) and distributed filesystems like CODA (which still aren't much of a commodity, they've just sorta migrated to "the cloud" with crap like Dropbox and Google Drive and MS OneDrive or whatever). I could walk up to any computer or device and access my desktop via VNC and keep working on whatever I was doing just as I had left it.

      In the mean time, it seems like everything was set back 10 years as everything got reinvented for mobile devices. Network speeds for mobile phones were roughly about 10 years behind desktop computing. Screen size and resolution was closer to about 20 years behind, which might explain why phone interfaces today look more like Windows 3.11 than ever.

      Perhaps the biggest difference is in price. Now that smartphones and computers are practically disposable, we've shifted from building highly reliable distributed systems to highly replaceable throwaway systems. Don't get too attached to the idea of a persistent remotely accessible virtual workspace, all your programs (I mean "apps") and interfaces you're accustomed to using will be thrown away during the next release cycle next week anyways.

  • All the leading OS still don't deviate much from traditional kernel design approaches, the main "innovation" i'm interested in for a modern OS is provable reliability... by provable i don't mean empirical and observable reliability (e.g FreeBSD), i mean reliable by design: There are some pretty innovative concepts beyond the basic microkernel concepts in Minix 3, and unlike it's predecessors it's intended to be more than an educational tool.
  • >" Nowadays OSX [MacOS] and [MS-]Windows caught up in these areas"

    Oh really? Perhaps quite a bit in just THOSE few areas which you listed, but in nowhere NEAR all the areas for which many of us continue to choose Linux. It is nice that Linux forced other operating systems to suck less than they used to, however :)

    >"and mainstream distros like Ubuntu dumbed down in default configuration."

    So then use one of the other [superior and yet excellent] Linux distros. I, for one, have never selected to use U

  • I find that Microsoft is really innovating in the user interface department these days.
  • Probably the most 'innovative' in that its approach is very non-tradititional. Seems like a good idea at this time:

      Qubes does integrate security context display into the window manager. That is, at least, some UI innovation the OP may be interested in. It also solves security problems with cut-and-paste between domains.

  • Nothing as far as a distro (or desktop environment) with 3D VR or AI comes to mind but there is innovation in OS going on. Not many have attempted to answer the OP, so here's my list. Others mentioned Qubes, Urbit, and Mirage.io, which reminded me of Nix OS and HaLVM.

    Both innovative and seems daily-driver ready:
    1. Qubes OS - https://www.qubes-os.org/ [qubes-os.org] - Linux distro that runs a Xen hypervisor to contain every app (including Windows ones) away from the desktop environment
    2. Haiku OS - https://www.haiku-os.org [haiku-os.org]
