Venkatesh Srinivas is making vmobj_token and vm_token much more fine-grained. That’s great, but watch out over the next few weeks as this work goes into 2.11. (i.e. don’t upgrade your DragonFly 2.11 unless you are ready for surprises.) Venkatesh has already found some.
Do you have a DragonFly workstation? That you play audio on? Do you have headphones hooked up? Is it using Intel High Definition Audio? (snd_hda) Does connecting the headphones disable the system speaker?
You can probably guess exactly what I’m trying to troubleshoot given the above questions.
Here’s two items I meant to post and for some reason did not:
- Sven Gaerner posted a short description of how he migrated his DragonFly system from a hard disk to a SSD. This may be useful for anyone considering a move. Decent-sized SSDs are reaching low prices these days.
- Tim Bisson posted an update on his work on TRIM support for DragonFly. The code is available now if you’re feeling lucky.
It’s World IPv6 Day. You can go to IPv6 right now with your DragonFly system. If your ISP doesn’t support IPv6, you can try a sixxs or HE tunnel. Also, nag your ISP about it.
The newest issue of the Open Source Business Resource is out, with this being a second issue on Technology Entrepreneurship.
The i386 architecture now supports LAPIC and I/O APIC. If you had weird interrupt problems when installing DragonFly before, now might be a good time to try the latest bleeding-edge version of DragonFly and see if the problem vanished.
Short but good this week.
- I always enjoy seeing other people’s window configs, even if I don’t use them.
- The CCBY license is very similar to the BSD license – and there’s some big institutions using it. That is good news for everyone.
- I linked to telehack before, but I didn’t realize how huge it was. There’s 25,000 virtual hosts in there, recreated from history, complete with realistic user lists. You can ‘hack’ into hosts, or run games and BASIC files. (hammurabi!) It even recreates early USENET. Read the description of what to do – it gets really interesting about halfway down. It’s an Internet Simulation, if ever there was one. (via)
- Remember I posted earlier this week about my results with deduplication? I had about a 7% gain of the disk. As time has gone on and the Hammer reblocker was able to work overnight, I’m now up to a gain of 10%. Neat!
- Also: I got Minecraft working (as a server) on DragonFly. See the comments on my original it’s-almost-working post.
- RAS Syndrome: Recursive Acronym Syndrome Syndrome. For anyone who has typed “GNU”. (via)
BSDTalk has a 17-minute interview with Josh Paetzel about FreeNAS 8. Every time Will Backman makes it to a convention with a tape recorder, we all benefit.
Sepherosa Ziehau’s made it possible for uniprocessor kernels to use the LAPIC and IOAPIC functions on x86_64, which means better timer support, less need to fiddle with configs, and more supported hardware. A win all around! Set hw.lapic_enable=”0″ if there’s trouble. The same changes for i386 are on the way.
The dragonflybsd.org network is going through some network changes; access may be spotty in the next… 24 hours?
The June issue of BSD Magazine is out, with the title being “NanoBSD and Alix”, but there’s plenty more articles in there. DragonFly news is on page 25 – if this month is better for me than last month, I hope to have more in there.
Stéphanie Ouillon has posted extensive details on the Virtio Google Summer of Code project; a few questions are included for anyone who wants to jump in and offer feedback.
I added a Google “+1” button to the site, over on the right. Not that the site really needs it, but it tickles me that they’re using an old (but still in use) meme for this idea. I’d link to places it was used on our own DragonFly mailing lists, but searching for “+1” isn’t working too well.
