DragonFlyBSD Team Interviewed

lowks writes "A nice little interview from the ONLamp BSD advocacy page where we get to peer a little into the goings ons and updates as well as plans for DragonFlyBSD. Highlights include the rationale behind DragonFlyBSD and peeks into the current engine as well as goodies planned to be implemented in the future versions. DragonFlyBSD is another flavour of BSD which forked from the FreeBSD 4.x branch not too long ago. It's headed by Matt Dillon, who forged out on his own and started DragonFlyBSD due to technical differences with the FreeBSD team ."

  1. OnLamp -- Hit or Miss by bhima · · Score: 4, Insightful
    It is just me or are the articles on OnLamp very hit or miss. When the are good, like this one, they are very good & when they are bad I can't even finish them!

    Or I suppose it could be that I'm mildly interested in Dragonfly and I think Matt et all have a strong argument in LWKT.

    Hmmm now I wonder what sort of SMP strategy is used in OS X??

      Mac OS X relies on XNU (modified Mach 3.0 + BSD) for SMP. As far as I know, it uses a mutex model (like linux, freebsd, & netbsd).

    Please. There are what, 300 different Linux distros?

    Guess what, different people have different goals and needs. Matt Doollon wanted to implement SMP in a different way than his (then) fellow FreeBSD developers had envisioned. NetBSD guys want to run on every platform out there. OpenBSD is about security.

    Go back to your cave if you have nothing to contribute, but don't tell people what to do with their free time.

  3. New BSD on the block by CustomFort · · Score: 4, Interesting

    It seems like this new DragonFLy BSD project could become very interesting. I have been wondering for a while what their exact purpose was for the split, and I think I like it. Their goal of implementing cleaner and more scalable structures sounds like a worthy one, even if it is a long tem goal.

    Who knows, someday the BSD world might break up lke this:
    OpenBSD is for Routers and firewalls
    NetBSD is for XBox/Toaster/microwave/everything else =P
    FreeBSD is for Servers
    and
    DragonBSD is for SSI Supercomputers or other highly scalable systems.

      This might come as a surprise for you, but all of the BSD are general purpose OS, even though they have different focus. There are quite a few OpenBSD servers out there, just as there are quite a few FreeBSD firewalls and routers, and the same goes for NetBSD. NetBSD has even set the TCP speed record over "the pond".

    They can now tell people: look we have 5 guys running FreeBSD, 5 guys running NetBSD, 5 guys running OpenBSD and 5 guys running DragBSD.

    Since we can safely assume that the *BSD developers are running their own OS, this implies that the 5 developers are very, very productive! So all the thousands of GNU/Linux kernel hackers quite simply can't match the quality, stability and speed of what is done by the 5 (five) *BSD hackers. By the way, the *BSD hackers has to develop userland in addition to kernel work ;-)

    Good News Everyone!
    Turns out that *BSD is stronger than ever!
    According to an Inernetnews article, Netcraft has confirmed that *BSD has "dramatically increased its market penetration over the last year."
    There has been a steady increase in *BSD developers over the past decade.
    There are currently 307 FreeBSD developers as of the 2004 core team election.

    Enjoy!

  6. Why, always...? by agraupe · · Score: 3, Insightful

    Why is it that, for any BSD article, half of the responses are standard, boring, retarded "BSD is dying" posts. I think it is just a bunch of linux evangelists with massive insecurities, just wanting to ensure that linux stays at the top of the heap when it comes to open-source operating systems. Who says that all competition has to come from Microsoft? It's not like they're amazing to begin with. (For the record: I am a happy Linux user. I tried OpenBSD, and found that I didn't like it. This does not stop me from realizing that some people like it more, and that it may be better for some purposes. At the moment, I am considering giving FreeBSD a try. Generally I'm open-minded towards all operating systems. Yes. Even Windows, to a lesser degree)

  7. New BSD Commercial Development Company by Anonymous Coward · · Score: 3, Informative

    It looks like BSD is gaining more market share now that ever before. There is a new company Crescent Anchor with a commercially supported BSD operating system called SilverOS which looks likes its based off of the upcoming release of DragonFly. Http://www.crescentanchor.com

    From reading through the site site the operating system looks very interesting. They already have a large client base, with some very respectable companies listed. I think I'll order a copy and at least give it a try as FreeBSD 4.x is what we use at work and I've noticed the development work on 4.x has slowed down a lot in the past year . SilverOS/DragonFly might be what we start running next. We've already been looking at DragonFly for some time now and if there is a company offering commercial support I can't see a reason not to start using it now.

  8. Re:Technical differences? by bmah · · Score: 2, Insightful

    Matt is still on some of the mailing lists. I've seen him recently (past several days) involved in some very deep technical discussions.

    I personally think that even if Matt had not lost his FreeBSD commit bit, he might have started DragonFly anyways. DF is an excellent vehicle for trying out some new architectural approaches to problems that are just fundamentally different from FreeBSD 5 was/is doing.
