It’s really neat to suddenly encounter something done just for DragonFly that you didn’t know was coming: A port of Go to DragonFly. I think these changes are going into the next Go release, or at least I hope so. (More on Go if you haven’t encountered it before.)
Just seen: EdgeBSD, a version of NetBSD with different goals in mind. (Seen on Hacker News)
The mailing list archives for DragonFly (lists.dragonflybsd.org) have been moved to new hardware. (Yay!) The patch that actually shows date in the listings needs to reapplied, cause Mailman is somewhat stale. (Boo!) I applied the patch and I’m regenerating all the archives now. (Yay!) There’s some garbled messages in the archives that cause a bunch of “no subject” partial messages to be dumped at the end. (Boo!) I’ll manually fix them if I can, someday. (Yay?)
Definitely Saturdays for this summary. In other BSDs this week:
- It’s FreeBSD, but it can apply to any BSD where a personal attribution license is used: Julian Elischer’s name comes with every iPhone.
- cxgbe(4) cards can now display their temperature under FreeBSD.
- ciss(4) supports additional HP RAID controllers under FreeBSD.
- Bind has been updated to 9.8.5-P2 in FreeBSD.
- FreeBSD has initial support for the Cubieboard 2.
- FreeBSD now has a USB test program.
- NetBSD supports some additional ZTE modem devices.
- NetBSD has cgram, a substitution-cipher solver. For amusement purposes?
- NetBSD supports the Nuvoton W83795G monitoring device.
- OpenBSD now supports wireless devices using the Ralink RT3060.
Wired has an article up about Jordan Hubbard and his move from Apple to iXsystems. It’s not a bad article, though it doesn’t delve into the why of BSD very much. In any case, iXsystems has been really bulking up lately to be more than a generic hardware provider.
Speaking of which, that blade system going in now for dragonflybsd.org was sold by iXsystems.
Several parts of dragonflybsd.org are moving to a new blade server, so there may be some service interruptions during the transition.
Joris Giovannangeli, one of the Summer of Code students for DragonFly, posted his thoughts on credential descriptors – have a read. He is working on capsicum and DragonFly, so this is a natural thought process.
Every year, people ask “Why can’t writing documentation be part of Summer of Code?” (Not necessarily for DragonFly, but in general) Google has a “Doc Camp”, where a whole lot of documentation gets produced in sprints, and anyone can participate – not just Summer of Code students.
If this sounds interesting to you, your application has to be in by August 7th 9th. (URL and date updated)
Please welcome our newest DragonFly committer: Johannes Hofmann. He earned this by coming up with a significant chunk of DragonFly’s upcoming KMS/915 support, and it’s now easier to just have him work directly than to be constantly committing for him.
Since there’s a newer set of dports binary packages uploaded, I thought I’d spend my weekend upgrading, to catch up.
‘pkg upgrade’
And that was it. Well, not really. I had to dump and restore my Postgres databases, cause of the switch from 9.0 to 9.2 as default. I had to build php5 from source to get the Apache module. Those two things together took longer than the entire download and upgrade of the rest of my system – some ~200 packages?
Sepherosa Ziehau added SO_REUSEPORT to DragonFly. I don’t know how the mechanism works, because he didn’t include a description, but he did include a explanation of just how much it reduces CPU usage during as-high-as-physically-possible network load. He even wrote tools to test it more heavily.
Some of the links this week go pretty in-depth. Enjoy!
- This short story from 1954 might serve as a reason to avoid single system image computing… (via Sascha Wildner)
- Vim and Ctags tips and tricks. (via)
- Psygnosis game box designs. Nostalgia for some, neat art for anyone else. (via)
- 50 years of ASCII, and here’s the table it comes from. Some other neat links there, too. (via)
- Richard Feynman and The Connection Machine. If you like stories about Feynman, who was a very interesting person, you may want to read Feynman, the comic book. I met the writer, Jim Ottaviani, years ago, and he was very energetic about both science and comics. Look up his other work if that sounds interesting – which it should. Here’s a sample from the Feynman book. (via)

Back to the Future: Preserving the History of Video Games. This is right around the corner from me. The game museum is as neat as it sounds (yes, they have games out to play), but the article doesn’t mention that it’s attached to a fantastic and huge kid’s museum.
- Building a Cray at home. Similar to this previously-linked idea. (via)
Your unrelated link(s) of the week: Candy Box and A Dark Room. Both are text-only games, but they use HTML5 for animation. They start minimal, and build up – be patient; there’s a lot of gameplay in there. These minimal games fascinate me. It’s like reading a book, where it goes from just static text to an entire world being built. (somewhat via)
Your bonus unrelated comics link of the week: Jack Kirby double-page spreads. It’s not an exaggeration to say this artwork crackles. (via I forget)
Whoops, I missed this when it happened, but: the freeze for pkgsrc-2013Q2 has started. That new quarterly release is anticipated for the end of the month.
Phoronix has another set of benchmarks that include DragonFly and PC-BSD, along with several Linux distributions. It’s interesting to see, though don’t take them as performance measurements. 7-Zip as a benchmark doesn’t describe much other than the program itself, and the Himeno benchmark results are because of the compiler in use rather than any underlying performance aspect of the operating system – for instance. The DragonFly benchmarks disappear after page 3.
I’ve tagged DragonFly 3.4.2. The major reasons for this point release were fixes for DragonFly under Xen with more than 2 CPUs specified, and for booting x86_64 DragonFly in KVM. The 3.4.2 tagged commit has every detail.
If you’ve already got a working 3.4.1 installation, you don’t need to rush to upgrade; this is mostly for the people affected by the issues listed above. I’m working on 3.4.2 install images; give that some time to complete and upload if you need one.
Rados?aw Szymczyszyn has manged to get support for DragonFly’s bootloader into GRUB. This is part of his Master’s project to make DragonFly multiboot capable, at least for i386.
(I love having new things show up from new people, out of the blue.)
Loïc BLOT posted about his benchmark of several operating systems using KVM and Postgres 9.1. Happily, DragonFly is the fastest, with one exception. Linux/ext4 comes out faster – if you run it with barrier=0, which can be dangerous in a non-battery-backed-up volume.
John Marino managed to update GCC from 4.7.2 to 4.7.3 (4.7 changelog), zlib from 1.2.7 to 1.2.8 (changelog), and awk from 20110810 to 20121220 (can’t find a changelog).
In other update news, Matt Dillon has been working on HAMMER2’s flush sequencing.
Update: tcsh too.
I’ve put the 3.4 release images up on terasaur, a Bittorrent seeding site. Please try pulling them and let me know how it goes. I haven’t torrented many things, so I am unsure how to even verbify “torrent’. Hopefully that sentence and those links work out.
If you’re looking to install DragonFly on a Kimsufi server, and you can read French, this explanation may help you. (via Enjolras on EFNet #dragonflybsd)
