Will wait for an update on Debian GNU/Hurd.

  The arch hurd team recently posted a message saying they were in stealth mode, very busy with their lives but not idle, I hope this will give them thirst to come back on a new release.

Why, GNU, Why did you have to make a kernel? Ok, I get that the GNU has always wanted to make an OS that they can get credit for (GNU/Linux folks, I'm looking at you), but still. I suppose that they can make the case for making a non-monolithic kernel, but that doesn't seem necessary to me. I feel like all the years of dev work on HURD could have been better spent on other projects, but it's not my time :( Thoughts?

  There are heaps of open source projects that do the same thing. Count the text editors, window managers, game emulators, audio players, the list goes on forever. This is the _second_ kernel in the same kind of space.

    First, actually. :-)

  Thoughts? Competition makes everybody better in the long run. Also, sometimes things are just ahead of their time, and don't "come into their own" until later. It's still entirely possible that Hurd will prove to be very important and useful for some class of application(s). I feel like all the years of dev work on HURD could have been better spent on other projects, but it's not my time Exactly. The people working on it chose to work on it, and none of us have any standing to tell them that they were wrong for doing so.
- vezzy-fnord 13y ago
  Because a kernel is an essential part of a complete operating system. So that they can get credit? I don't think the GNU Project had anything to do with achieving reputation, but rather to spread an ideal of free software. Hurd development has been pretty sporadic in general. Just look at GNU's project catalogue: it's vast. That said, if Stallman hadn't egotistically intervened into Bushnell's original plan to adopt the 4.4BSD kernel, the Hurd could have stood a chance. But no development is a waste.

  Why not? There's always room for improvement. Beats another JS app framework.

  It was very detrimental for the project, but it's a key part of the research/thinking/design. If you watch Hurd demos, you'll quickly see how moving bits outside the kernel gives a lot of freedom to the users. In terms of ideas and performance. Samuel Thibault 2011 (fragile) demo included mounting an iso image from a ftp in a matter of seconds. This pops from the OS design.

  I feel like all the years of dev work on HURD could have been better spent on other projects, but it's not my time For many years, it's been the effort of a handful of volunteers. Lots of GNU development has continued aside from HURD, so it's not as if HURD development has been a significant drain on getting any other useful work done. http://www.gnu.org/software/hurd/faq/how_many_developers.html http://www.gnu.org/software/hurd/faq/how_many_developers.htm...

  Thanks for all the answers. I can understand why people are making HURD, but I'll stick to Linux for now :P.

  Not GNU projects but relevant and different kernels / operating systems: http://www.barrelfish.org/ http://www.barrelfish.org/ https://github.com/xomboverlord/xomb https://github.com/xomboverlord/xomb http://www.returninfinity.com/baremetal.html http://www.returninfinity.com/baremetal.html http://en.wikipedia.org/wiki/SeL4 http://en.wikipedia.org/wiki/SeL4 I don't consider any of these to be a waste of time in the least; some move quicker than others but ultimately every one of these projects is advancing the state of the art and we may one day see the fruit of this difficult type of work (building kernels from scratch).
  - axaxs 13y ago
    Don't forget templeos...as trippy as it is.
    - symisc_devel 13y ago
      Absolutely, TempleOS is an amazing piece of work including its programming language (Holy C).
      - axaxs 13y ago
        Completely agreed. I wonder if it will ever 'leave' his hands, as it really is a nice language, a well thought out C improvement (for the uninitiated - http://www.templeos.org/Wb/Doc/HolyC.html http://www.templeos.org/Wb/Doc/HolyC.html ). I'm very versed with who the creator is, and his personality, but honestly think he may be one of the smartest people in the field. It's a shame more people don't take him seriously(and to their point, I don't always blame them).
        supergauntlet 13y ago
        People tend to not take crazy people seriously. That's kinda sad because the guy is indeed one of the smartest people in the field. I just hope he gets some help and is able to work his issues out.

  It's not wasted. I've seen the design concepts of HURD as an inspiration for other projects and people experimented with them. Even I got some (dumbed down) ideas that I didn't limit to software. Sometimes I think there's some similarity to the SOA approach (pretty everything's a server/service), just that HURD had the ideas earlier. But that might be a too high-level view now.

  For one, recall that the HURD project was started before Linux. At the time, there was no free Unix-like kernel they could work on; the rest of GNU had been developed on proprietary kernels. > I feel like all the years of dev work on HURD could have been better spent on other projects, but it's not my time :( I don't really think it's nearly as many developer years as you think. HURD isn't that big a project; it's a few people, working on what they want to work on. Most of the actual development effort goes into the Linux kernel. There's room for more than one free kernel out there. Heck, there's room for a lot. There are still people using and developing FreeBSD, NetBSD, OpenBSD, DragonflyBSD, Darwin, Haiku, ReactOS, and more.
  - ChuckMcM 13y ago
    This. If you read RMS' announcement for GNU [1] it had to have a kernel because in 1983 there wasn't a kernel. And an "operating system" was defined as its kernel, its compiler, and the tools around that and using it in day to day work. So it starts first on a compiler, then to basic libraries, and then to a kernel. I applaud the team for continuing on the path set forth in that announcement.

  As someone else mentioned, the HURD was started before Linux existed back when micro-kernels was all the rage in academia. Stallman said that by using the mach-kernel they hoped to get finished faster, as it turned out this was a big mistake which he acknowledged as his own and as soon as Linux took off they started focusing on improving the GNU toolchain in conjunction with Linux. The Hurd is still in development today because there are people who like working on it during their spare-time, just like all the other alternative kernel/os projects out there.
- zanny 13y ago
  I'd argue that from the perspective of an operating system vetting security, a good microkernel implementation with userspace drivers would be a great win. Even when you can vet the entire linux code base (for the most part) and use only the free drivers, you still have multiple attack vectors available to possibly get code running in kernel space. Which is bad. A lot of people (myself included) probably don't think Linux is the last kernel to rule them all, ever. It doesn't distribute itself well, it is quite large, and its speed is derived from its massive developer staff. Simplifying your kernel doesn't really matter when it has hundreds of active contributors, but what about in a hundred years when all the current Linux devs are gone, and you have to try to get new generations to adopt the code base and maintain it?
hereonbusiness 13y ago
I'm actually curios, is this used in production on a mid/large scale anywhere ? First hand experiences?

  If someone answers this in the positive (which I doubt), I'd like to tack on the further question "what was so amazing about this software that made you start using it long enough ago, while it was so far in its very slow to come to fruition infancy, that by the time the software reached 0.5 you already had a large scale deployment" ;P.
luckydude 13y ago
OK, I'll nerd out here for a second. I knew some of the QNX guys, work:~ call qnx Dan Hildebrandt (QNX) 613-591-0931 x204 (RIP 1998) That's me using my phone database. Dan was one of the few people who were allowed to touch the QNX core. It was tiny, it knew that the "micro" in microkernel meant small. The entire kernel fit in a 4K instruction cache. The whole thing. Hello people! Micro means small. For the people out there that understand operating system design, these guys got it. And they managed to make a distributed kernel that worked. I worked on an 80286 (yup) with ~10 users logged in and working. I'll give more details if anyone cares. All that said, please allow me to vent about Mach. I know nothing about hurd. Mach was CMU project and it was what happens when you let a bunch of people who know nothing about the real world write wack on an OS (and a VM system). It was happening at the same time I was getting a decent education from Uwisc. So it took me a while to catch up. I caught up after having worked on a Unix port. I learned a lot, as would any of you in the same situation. Practice != theory. I went back to grad school to get a PhD and ran into a class where they were pushing Mach and I listened for 15 minutes and then I just couldn't take it any more and stood up and said "it doesn't work like that". The prof and I went back and forth for a few minutes and then I took over the class and taught it. Blah, blah, blah, I haven't really made the case against mach. I have wife and kids waiting on me, I can come back and try and do better. My view of mach is that it added nothing to the body of OS work. BSD did - they added networking. Sun did - they added VM. QNX did - they added a microkernel. Mach - they added marketing in my opinion and nothing else.
- luckydude 13y ago
  Going to bed but I hope some of the other nerdy OS guys chime in. I suspect they feel the same. What would be interesting is not a post about how GNU is going to do what has already been done but instead how they are going to do something that hasn't been done. In one dimension, free vs paid, GNU has won and won big. That's not quite right. Open source has won and won big. Not fair to let the FSF get all the credit (believe me I can go on and on about that). But in another dimension, innovation, building something the world has not yet seen? Hmm. I'd be very impressed to see that announcement from the FSF. That would be awesome.
