Among other changes to pkgin 0.5 (available in pkgsrc-wip but not pkgsrc-2011Q3), it now notices if you need a newer pkg_install because you’ve shifted to a more recent quarterly release of pkgsrc, and grabs the appropriate binary package to fix that. Thanks, iMil!
Getting close to 2.12 release…
- Steam and Team Fortress 2 running on a BSD – PC-BSD with an NVIDIA driver, in this case, but it may apply to other cards and other games. Using Wine is always so intricate, it seems.
- Remember how suddenly a large chunk of Internet traffic was suddenly routed through China, briefly in early 2010? Apparently it’s happened a few more times since then. This article at the Economist talks about that and the SCION project, in an accessible way.
- The 2011 Interactive Fiction Competition has released this year’s entries, and almost all of them can be played online. (via) There goes a few hours of your life. Sorry.
- Speaking of hours, there’s apparently a civil lawsuit that has rendered timezone data unavailable. Here’s a good summation. It’s a frustrating scenario. (via multiple places)
- World’s best introduction to sed.
User ‘Zenny’ asked questions about setting up a server similar to ones described in this presentation, except using DragonFly and Hammer. Most of it is possible now, going by the thread.
Tim Bisson’s work on TRIM support has been committed. I don’t know if it will show in 2.12, but it’s off by default so it would seem a safe move.
There’s only one multiprocessing bottleneck left in DragonFly: vm_token. Matthew Dillon’s working on removing it, and he’s been testing his initial results on a 4-core machine and a 48-core machine, using heavily parallelized buildworlds to test concurrency. He’s posted the results, showing an initial speedup of up to 30%. This definitely isn’t going to make it into 2.12, but it’s looking good already. Keep in mind these are improvements on top of the performance graphed here yesterday.
Technology Innovation Management Review, the replacement for the Open Source Business Resource, has its first issue out. There’s still an open source focus, despite the name change.
Venkatesh Srinivas sent along a graph of his nmalloc testing that shows mysql threading performance on DragonFly, from slightly over a year ago. Both graphs were done on a 4-core system, though I don’t know if the specs are comparable, so the curve is important. Look at the just-posted curve for comparison. That’s how much things have improved.
In fact, here’s a cheesy overlay, cropping the more recent results and laying the old ones on top of it. The black lines are the year-ago performance, and the colored lines are the performance now.
Samuel Greear has graphed out the performance of both MySQL and Postgres on DragonFly 2.12 as you add threads. There’s a very nice correlation on performance and number of cores. For comparison, there’s this old test from 2007 which shows uniprocessor performance to be good but not improved by adding cores. The tests were on completely different hardware, so the actual curve of the graph is the telling point.
As he points out in his post, excellent multiprocessor performance is arriving on DragonFly, without any catastrophic shifts or destabilizing changes.
The 2.12 branching generated a list of every DragonFly commit since 2.10, grouped by committer. Good to browse through. Try to ignore the part where it shows the measly 4 things I did, with poorly constructed commit messages.
You’ll see Steve Jobs memorials all over the place for the next few days, but here’s something that won’t get mentioned much: He probably is responsible for putting UNIX – real, BSD-based UNIX – in the hands of more people than anyone else, ever.
It’s not the 2.12 release yet – just the initial branch of 2.12. This will become the release version of 2.12 in a few weeks.
The latest quarterly release of pkgsrc is out. You can download it via CVS, or update /usr/Makefile to pull down the correct branch. I’ll be building binaries as soon as I can. I like the release announcement style.
Yep, fall hits and it’s easier to find links.
- DragonFly morphology. The insect, not the operating system, though that would make an interesting diagram.
- Stick your pinkie in the corner of your mouth, Dr. Evil style, and say, “One MEEELion TCP connections on BSD!“. (via several retweets)
- Sudo vs. SSH public keys.
- The app store concept is taking over. Not that it’s a totally bad thing! We could implement one for pkgsrc, and should. (via)
- A nice (OpenBSD-centric) walkthrough of routing. (via)
- Ooh, decent disk benchmarks. I wish there were graphs, of course.
- I think this happens to most CS grads; you sit around one day and say to yourself, “Hey, I could write an operating system!” This forum post shows someone getting that idea and then realizing it’s not necessarily the goal he wanted. Why do I link to it? I appreciate the optimism.
- Or you can just build a functioning computer in Minecraft. This sort of thing has been happening for a while – this movie is just a link to the craziest example I’ve seen so far.
Your unrelated link of the week: Scientific Illustration. Not a comic, but still visually interesting.
Did you notice zgrep went missing? Well, it’s available again, thanks to YONETANI Tomokazu.
The Open Source Business Resource, linked here before, has become the Technology Innovation Management Review, or TIM Review. Conveniently, the editor is named Chris, not Tim, so nobody will get confused. It’ll still cover open-source software, but it’ll also
“share the spotlight with topics such as managing innovation, technology entrepreneurship, and economic development”
The first relaunched issue will be out in October.
A position opened up for a junior systems administrator at my workplace. You have to be willing to live near Rochester, NY, administrate a mix of Windows and unixy machines, do desktop support, and network management. (e.g. everything possible) The work environment is neat, informal, and somewhat adverse. I’ll have a job description soon, I hope.
Michael W. Lucas is setting up two DragonFly machines, to try out Hammer. I linked to his tweet about this in the last Lazy Reading post, but this is a more in-depth explanation of what he’s doing. So far, it just works. (as seen on Reddit, too.)
I finished a build of pkgsrc-current on x86_64, with a report on what built. I’ve kicked off a new build, and I expect at least 100 more packages to build thanks to John Marino’s work on pkgsrc and DragonFly.
Want to create getcontext for DragonFly/x86_64? Apparently we need it.
