Alex Hornung posted a description of the work he’s done so far on a new I/O scheduler, with some details on his ideas on multiple scheduler levels. Feedback is welcomed.
Month: February 2009
RUE Beltelecom has a DragonFly mirror; it includes images, snapshots, and binary packages. It’s already listed on the download page on the DragonFly website, too.
Matthias Schmidt readded the CVS DragonFly template. However, git being git, you have to manually bring it down to your local clone of the repo. Do this with:
git config --add commit.template /usr/src/tools/gittemplate
If you can see YouTube, you can see a 20-minute presentation from a Philip Johnson about his experiences from Google Summer of Code 2008, where he was a mentor for another project. If you aren’t familiar with the Summer of Code project, or think that you might participate as a student, this is a good introduction to the concept.
Incidentally, his wife’s books are good, and wierd, and I read them long before I had any real idea who Rob Pike was, in a wierd bit of synchronicity. Early computer science history would be a good topic for Jim Ottaviani to publish, come to think of it… (also recommended)
For anyone interested in profiling: I posted details on a bulk build of pkgsrc that seem to imply it’s limited by something other than CPU. The ensuing discussion had some ideas on how to speed up the whole process.
I’ve set up another mirror at df.v12.su, on some equipment/space/bandwidth kindly donated by GP Internet.
Freddie Cash has an interesting writeup of how he put together a very capable and cheap backup system using ZFS; this is part of a larger discussion on Hammer, ZFS, performance and solutions.
I’ve updated the website section of the Projects page on the DragonFly website; if you were looking for some things to clear up, some of them are relatively trivial.
As I try to catch up with a large backlog of messages (I was traveling), I’ll note that Sepherosa Ziehau has done a lot of work on network card support and Sascha Wildner on WARNS cleanup; both of them have made so many commits in the last few days I’m just going to throw up my hands and point at the date index for this month’s commits.
DragonFly 2.2 is released! Visit the release page for details. As always, please use a mirror when downloading.
This post on Blog Pseudoaccidentale described, by way of a parable, how many people think, incorrectly, they can’t contribute to open source. (The article says “FreeBSD”, but the rule applies to any open source project) It’s a matter of doing something, no matter how small, consistently.
I’d even use that analogy differently and say, “How do you eat an elephant?” Hint: see title.
(Thanks, Matthias Schmidt, for the link)
From O’Reilly: a love note for UNIX. Today’s the day for it, after all.
The wiki from Summer of Code 2008 has been opened up to the world and is being treated as a general resource for mentors and students, so please consult it if you are thing of being either one of those things.
Also, a FAQ for the 2009 session is together. Applications start in March, so get yourself together…
Update: Dates mentioned here, by me.
There’s an extensive article on “Unix’s Magical Moment” up on the O’Reilly site, with more details about that upcoming 1234567890 epoch time. That moment is probably happening very close to the same time you are reading this.
Matthew Dillon has updated pkg_radd to download based on the uname of the system where it’s run. This means binary downloads can be keyed to the appropriate release, instead of just whatever’s most recent on pkgbox or any of the mirrors.
Matthew Dillon posted another summary of the road to the 2.2 release, scheduled forFebruary 15th. Among other things, this release will be available in a LiveDVD form which looks to be about a gigabyte in size with all the added packages.
The FreeBSD Foundation is looking to give people money to work. (pdf) Specifically, they have USD $30K to give to people wanting to work on FreeBSD subsystems. Fight global recession!
I’ve updated the images page on the DragonFly site. It now has some added wallpaper and DragonFly badges for you to use as needed, and it’s all thumbnailed to make it easier to browse.
I like the smaller font size on the DragonFly website, because it packs in more information, but it throws off the visual balance of the sidebar. How about: http://leaf.dragonflybsd.org/~justin/testblock/ ?
Matthias Schmidt has created a page for DragonFly project ideas, for Google’s Summer of Code 2009. (Nobody’s accepted yet, but we were last year and I’m optimistic we can be again) If you would be available to mentor, add projects you’d enjoy mentoring. If you’ll be an eligible student, give it a read.
Dru Lavigne was at DCBSDCon, and her initial notes mention Robert Luciani’s talk on threading in DragonFly.
@Play has a new column up, this one about “Spelunky”, a tile-based underground exploration game. This game’s new and has been getting some buzz; it’s a sidescroller game that has aspects of roguelike play.
Also, this column is the 50th @Play column and, at the bottom of the page, has a nice list of past articles by topic.
One last build of pkgsrc 2008Q4 is complete on pkgbox.dragonflybsd.org; 2008Q4 packages for 2.2 will be available at time of release.
The epoch time is going to reach 1234567890 near Valentine’s Day, as noticed by Hubert Feyrer. The extreme nerdiness of that moment makes it that much more entertaining.
Thanks to Matthias Schmidt donating some machine time, I have pkgsrc 2008Q4 packages built for a recent DragonFly 2.1 system but labeled 2.2 already built. They’re uploaded to pkgbox.dragonflybsd.org and should be available on a mirror by the time of the 2.2 release.
As Simon ‘corecode’ Schubert notes, DragonFly is now in a ‘Feature Freeze’ for two weeks. Please work on bug fixes in the intervening timeframe, and push them to the ‘master’ branch. Changes for the release will be pushed to the 2.2 release branch. Matthew Dillon has more details.
This has been all over the Intarwebs at this point, but: there’s a good rumor that the next Sidekick phone will be running NetBSD on the inside. Danger, the company that makes the Sidekick, was bought by Microsoft, which makes this a BSD-based phone produced by Microsoft. I never thought I’d type that sequence of words together.
The February issue of the Open Source Business Resource is out, focusing on “Commercialization”.
A post from Matthew Dillon notes that development will go into a ‘mini-freeze’ for two weeks while the 2.2 release is put together, along with news of a DVD release for 2.2 that includes many prebuilt packages, and some Hammer details.
