Audio recordings of the events at BSDCan 2011 are now available, in mp3 form. If the file names aren’t descriptive enough, you can go through the speaker list and match up. (found indirectly via Facebook)
The pkgsrc ‘freeze’ in preparation for the pkgsrc-2011Q2 branch is coming up, starting this Sunday the 19th. This means the quarterly release will be tagged in about 2 weeks, and I’ll probably have binary packages built for DragonFly about a week or so after that.
BSDDay Argentina is starting to look for speakers. The official site doesn’t list 2011 dates yet, but it’ll be in November, in Buenos Aires. (via Damian Vicino) Alex Hornung gave a DragonFly presentation there last year…
There’s still a few packages in pkgsrc that don’t support DESTDIR (e.g. being built by someone other than root). If you want to help out, here’s a list of those 60 packages.
A nice big pile of links this week. Some of these may have cropped other places by now, but oh well.
- An interview with Dennis Richie about inventing Unix. (via) I like that he sounds just absolutely tickled that there’s a version of ‘his’ operating system on his phone.
- A nice article describing Project Euler, for those who want to program; or program more. (via several places)
- Michael Lucas points out something that isn’t new but still needs reinforcement: avoid SSH1.
- Anecdotal evidence that SSD drives fail a lot. On the other hand, the bulk builds I’ve done of pkgsrc have worked the crap out of several SSDs and I haven’t killed a single one.
- Weird things in IPv6 routing. (indirectly via this, via ftigeot on #dragonflybsd IRC)
- Aw, Google’s BSD-specific search page is gone. Not that it was really needed at this point; I hadn’t seen a difference in the search results for some time. There’s more pressing issues.
- The FreeBSD Foundation has a trip report from Sergio Ligregni and from Thomas Abthorpe, from sponsored trips to BSDCan 2011. I’d encourage everyone to make it to a BSD convention – it’s energizing to see others working on BSD, in person.
- I don’t think you really need a guide for this. (via)
- Emacs user at work.
- Totally unrelated: best dubstep video ever.
The Open Source Business Resource magazine is going with a rare unthemed issue in August. So, this is your chance to get published on your own specific business/open source topic! Articles are due by July 10th.
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.
Fresh from BSDCan 2011, an interview with Ingo Schwartze and Kristaps Dzonsons, mostly about mdocml. (Which is already present in DragonFly.)
