OpenBSD - f2k7 @ Vienna

Contributed by robert on from the fsck dept.

Two days ago f2k7, the OpenBSD Filesystem Hackathon, started in Vienna, Austria. 14 developers from the americas and europe have gathered in a building of the university of Vienna to discuss future directions of filesystem related works and actually start on it. This includes work around ffs2 in order to support partitions and filesystems bigger than 1TB, NFS cleanup, and work on improving the buffer cache.

At this hackathon we also have some visiting developers who work on topics not directly related to filesystems like rthreads, 10Gb drivers and SMP.

This hackathon wouldn't have been possible without the generous help of our users. Many of whom donated money or hardware and some of whom even managed to convince some companys to lend us some nice big servers. In particular I'd like to thank Stephan A. Rickauer of FOSS@UZH, Jean-Gerard Pailloncy, Dalco, Dell, GeNUA, LSI, Mobilkom Austria and Transtec.

    Hello guys,

    Nice to hear the next hackathon is running!
    Please don't forget to post some feedback and pictures about the event!

    Happy hacking !!! ;-))

    With FreeBSD having just announced initial support for zfs, is there a chance the kernel hooks for it will be created during this FS hackathon? I admit that I've not yet looked at the support or licensing, but I suspect it would be a good thing for OpenBSD to have.

      Or not. Just looked at FreeBSDs import, and it does have the CDDL license from OpenSolaris. Which makes it mostly incompatible with OpenBSD, I believe.

        You believe correctly, Unless they implement ZFS entirely under BSD or ISC, You can bet they "won't" add support.

        It's not like it's a big loss either ;-)

      While ZFS has some impressive features, it doesn't mean that every OS should port that code.

      Given the strong background of Matthew Dillon, it would be probably wiser to closely follow the HAMMER / ANVIL filesystem development from DragonFlyBSD. Mat chose that way over ZFS for good reasons. And it will be BSD-licensed.

        But it will likely require a lot of random shite from DragonFly if one were to get it working on another system.

          Yes, DragonFlyBSD has now a very clean VFS layer.

          But what's your point? ZFS has been designed for Solaris and relies upon a lot of "random shite" from Solaris.

        Agreed, but when re-inventing the wheel, it's good to have a basis to start from. Granted, the license issues won't permit it to be pulled in.

        I can't seem to find much on it outside of some slightly cryptic email threads.

        Got some resources or similar where I can read up on it?

    Is there some way to get in touch with the people attending f2k7 (when they are doing something else than working... perhaps)?
    I live in Vienna and I'm merely a OpenBSD user, but this sounds interesting.
    I have to admit that I have no idea how a hackathon usually works...

      the hackathon usually goes like this: wake up from drunken stupor, stagger into the code room, start writing code. someone swears loudly, people go over to investigate, questions are asked, ideas are had. more code is written. more questions, more comments, more retorts, more ideas. someone yells about who chose the music. more code too. break time for food. ideas comments and questions abound during food. after food: more code. someone realizes the bar is open, so drink time. beer + developers = ideas about code. swearing about vendors that lie in white papers. stagger back to bed, sleep it off. wake up from drunken stupor, stagger back into the code room, start writing code....


      you get the idea. its very intense, and people are generally working on stuff the entire time.

        But thanks to the others who explained the concept of hackathon to me. I expected something quite like this, but with some additional relaxation time inbetween ;) (after all you're in Vienna^^).

    Why are most of the hackathons in countries other than Canada (where Theo is)? Why not more local like Vancouver, Victoria, Calgary, Edmonton, Toronto, Ottawa, Montreal, Winnipeg, etc?

    Personally, I would love to see other places like Vienna and the other places these hackathons have been held at, but I'm just simply curious.

    What about long distance Video/Audio conference equipment, is that an option for other 'mini-hackathons' too?

      I myself hate the fact the hackathons are never local... But maybe they could at least offer audio/video of such events.

      I'd love to hear the developers talking amongst themselves, about coding.. beer.. etc.

      Pretty pretty please?

            I am sorry if I sound rude. But we developers like being able to work without being distracted by unexpected events or people we don't know.

            There is nothing wrong with having beers or whatever with OpenBSD users when you happen to be visiting their city, but hacking events are intended to be private. (And I can discuss this further around a beer if you'd like to (-: )

            Could you maybe explain this personal hygiene thing? I can't figure it out. My research is below:

            $ man personal hygiene
            man: no entry for personal in the manual.
            man: no entry for hygiene in the manual.

        "Developers work much better when they are physically promiscuous." Hackathon money goes towards hiring them prostitutes for a job well done?
