      I can't think of anything to say. Of course, the "article" didn't really provide much to talk about.

      Here's the Changelog [netbsd.org]. To summarise, there's a new 1:1 threading implementation, as the previous M:N one was too complex to maintain. Along with this change has come a considerable performance boost and improved scalability, especially on SMP machines. Impressively, most of this work has been down to one developer, Andrew Doran. The second most important change is a switch to Xorg on most platforms. This took so long because NetBSD had a large number of changes in their tree for more obscure platforms - changes that were not integrated back into XFree86 before the Xorg fork. There is also a journaled filesystem that essentially obsoletes the troublesome softdeps. Like ext3 in the Linux world, the new journal features were added to the existing ffs ("fast file system") rather than being an entirely new filesystem. Other changes include a plethora of new device drivers and updated third party applications.

      • Can the 64-bit Fast File System support more than 4TB yet? FFS has been 64-bit for a long time, yet is still stuck at a 32-bit limit of only 4TB with a 2KB frag size.

        Why only 2^31 fragment blocks with the 64-bit FFS? XFS is 64-bit and can support 9 exabytes.

          Soft dependencies were originally written as a FreeBSD feature, and then ported to NetBSD. I don't know how reliable it is on FreeBSD, but it has proved troublesome for some people on NetBSD, and getting to the bottom of it has been problematic since the code is rather complex. There hasn't been much enthusiasm to continue looking into the problems, and that's increasingly the case now that NetBSD has its own journaled filesystem.

      NetBSD is small, stable, and fast as hell. It is not really meant for use on the desktop, though many people do (including me). I mainly use it to build small, single purpose servers that I never want to have to look at again, and it's perfect for it.

      It's also where a lot of neat code sees its first light of day in the *BSD systems; over the years NetBSD has lent parts of its code to the other two BSDs, and therefore (de-facto) to Windows, Linux, and OS X.

      But no, it's probably not going to make you very happy as a desktop operating system.

          THe fact that it's small helps contribute to its speed, I imagine.

          Having not run to NetBSD on a desktop and compared it to linux, I can only guess that it's for similar reasons to why previous linux kernels (2.2, 2.4) were faster than the current one: they weren't primarily being developed by people looking to create a fast server, but hobbiests who's primary metric for "speed" was the responsiveness of the system it's running on. This is great for people who want a responsive, fast system.

      If you have old or somewhat unusual hardware, NetBSD does quite well.

      I have a Sun Ultra 1, circa 1995, that I pulled out of the closet for fun recently. Debian installs on it, but 1) is sluggish, and 2) doesn't support certain hardware. My machine has a PCMCIA adapter in it, and I have an old 802.11b PCMCIA card, so I thought I'd be able to use wireless on this machine.

      Turns out no Linux drivers exist for the PCMCIA adapter, whereas in NetBSD they do. After a kernel recompilation, the Ultra 1 is up and running on the wireless network.

        The main problem is that they're such a hassle to install, compared to a modern Linux distro. Last time I checked it out, NetBSD was worse than FreeBSD in this regard, and probably tied with OpenBSD.

        I installed NetBSD a few weeks ago, and it's not all that bad. It doesn't seem any worse than Debian. Sure, you have what size partitions you want and stuff like that, but if you can't handle that, you probably shouldn't be installing a new operating system.

      Here are some reasons:

      1) Linus "Testing is for someone else" Torvalds isn't running the show, and therefore you're more likely to get a properly tested kernel.
      2) You can download an official kernel and expect for it to not only build using your old configuration, but to not have a previously-working driver not work any longer.
      3) It has nice tools for doing #2, whereas in Linux, 'make oldconfig' has been seemingly abandoned in the name of progress and "let the distros handle it"
      4) Slower, more thorough release cycle which is still aware of "development" and "stable" branches

          You should throw the rubbish in a bin before you start the vax. If you don't, you'll just waste lots of electricity, with the thing running forever and making no progress, because there's a bag stopping the suction.

        • Back when I worked on VMS one of our windows developers trotted up with a VLC. Apparently his friend had bought one at an auction, and assumed he could throw windows on it. Its a shame I didn't know about NetBSD at the time (it would have been in version. 1.* or so).

      What's wrong with virtual machines?
    • But hey, I happened to have the hardware, and since of course it runs NetBSD, it's a learning experience if nothing else.

      As another learning experience you should try finding practically any PC made in the last 7-8 years, get virtualization software set up and do all of that in VMs and learn how to save a bunch of time and electricity.

      • Cool, but where can I get this mythical virtualisation software that allows me to replace a PDP-11 or VAX? Oh, I can't. And no, SIMH doesn't count - it's emulation software, not virtualisation software. Not that either can provide the kind of hardware support that many industrial applications for PDPs and VAX rely on - ever tried sticking a card designed for a PDP backplane into a PC? As for "any PC in the last 7-8 years", the x86 platform only got basic hardware support for virtualisation a couple of years

          Industrial applications? A Niagra or IBM 360?? Hardware virtualization on X86?? Not sure what you're talking about here, but we're talking about somebody installing NetBSD on ancient hardware to play with sendmail. A cheap junk desktop PC will accomplish that a lot more easily.

    I'm a proud NetBSD user for sure. I still use 3.1 on an old HP Omnibook 800ct. It works wonders on that Pentium 133 with 16mb of RAM. Boots in about 30 seconds or so, and WiFi works too. Not only is a great learning tool for aspiring people wanting to learn a good Unix, but it has a lot of good factors that experienced users look for in a good OS. Pretty decent driver support, a super small and quick installation, powerful security, a great list of binary packages, a large /usr/pkgsrc similar to /usr/ports, not to mention an excellent community of developers that are always willing to help a brotha out. Thanks to the dudes on Freenode and the NetBSD mailing lists for all their help. I'm looking forward to this release.

      How sad. No offense meant, but if you are proud about the OS you use, you really, really, really should try to get a life.
