Time to try IPv6
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.
OSBR: Technology Entrepreneurship (ag...
The newest issue of the Open Source Business Resource is out, with this being a second issue on Technology Entrepreneurship.
i386, LAPIC, IOAPIC
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. ThereR [...]
BSDTalk 205: Josh Paetzel and FreeNAS
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.
Say hello to LAPIC and IOAPIC, single...
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.
dragonflybsd.org renumbering
The dragonflybsd.org network is going through some network changes; access may be spotty in the next… 24 hours?
BSD Magazine: NanoBSD and Alix
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.
Virtio block driver progress
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.
+1 for the site
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.
BSDTalk 204: Ingo Schwartze, Kristaps...
Fresh from BSDCan 2011, an interview with Ingo Schwartze and Kristaps Dzonsons, mostly about mdocml. (Which is already present in DragonFly.)
Trying out deduplication
I moved to DragonFly 2.10 over the past few days, and I tried out deduplication, to see what kind of results I would get. The procedure is outlined below. I’m using /home here as an example, just to reduce the amount of text pasted in.

Whee!
Do you like the Opera browser? Apparently all it takes is a little misspelling to confuse it with a U.S. daytime talk show host. The “Best of Oprah emails to Opera“. (via) Mistaken identity on the Internet is always fun.
Popular free software licenses, described. (via) One of the better, non-polemic descriptions (Re [...]
Another pkgsrc build
This new build is on x86_64, pkgsrc-2011Q1. It’s already uploaded, if you want to update. i386 coming soon. Several packages freeze up during build, so it’s been turning into a manual process.
Minecraft! On DragonFly! Almost!
I managed to build openjdk7 on a DragonFly 2.9 system, and run a Minecraft server… but I can’t connect to it. Anyone want to hazard a guess as to why? I haven’t used Java much in the past few years, so I’m not sure where to troubleshoot.
Other Summer of Code: pkgsrc
One of the Google Summer of Code projects that will be valuable for DragonFly even though it isn’t a DragonFly project: “Add other package formats to pkgsrc”, where pkgsrc can interpret rpm, dpkg, and FreeBSD Ports files. Anyway, the project has a Sourceforge site.
Getting started with disk encryption
I haven’t covered recent disk encryption work evenly, here, so I’ll point at a recent discussion instead. Alex Hornung mentioned a cryptsetup(8) man page that may help, as does any dm-crypt tutorial out there on the Internet. (DragonFly has the same userland tools.) The DragonFly installer will create encrypted disks at instal [...]
Hot-swap and a bad disk
If you follow this thread, it has some discussion on how to handle a multi-disk setup and Hammer. If a disk is going bad, you can try mirroring, though you have to be careful how your pseudo-file systems are set up.
SMP by default
The SMP option is now in the GENERIC kernel config. This means you’ll have a SMP-capable kernel even on an uniprocessor machine, unless you configure a special kernel.
NTFS vs. battlestar
Apparently the mail(1) and battlestar(6) source code caused a problem when checked out onto a NTFS volume. Sascha Wildner fixed it, and Alexander Polakov found an explanation as to why. How long has this problem been around? Well, look at the email addresses at the end of the man page for battlestar(6), for instance, or guess how (Read mo [...]
