Thanks to a reminder from IRC user ‘cgag’, I’ve put an uncompressed ISO image of DragonFly 4.6 up on the main site. It’s linked on the download page, and should be available within 24 hours on the mirrors. If you are buying service from a virtual host provider, and can install an operating system directly from a downloadable URL, this is for you.
“Where is RC1?” you may ask? I tagged the first release candidate some days ago, and this bug was immediately found right after. It was easier to go right to RC2 once a fix was found.
This candidate will probably lead directly to a release version, so if you want to run the release version exactly, wait a few days.
The NYCBUG meeting happening tomorrow night, June 6th, is on the two different BSDs (RetroBSD and LiteBSD) that can run on the super-tiny PIC32 microcontroller. Go if you are near.
The system I had for running a go builder died. I am running out of extra hardware. Is there someone who is using Go and DragonFly and is willing to commit to running a semi-dedicated builder?
There’s a new digital library in Kisumu, Kenya – and it’s running DragonFly for file storage.
Tomohiro Kasumi wrote a lengthy explanation of what “@@” means, in the context of the Hammer file system. It acts as a sort of signifier for each actual Hammer pseudo-file-system, since it’s possible to null-mount these anywhere in DragonFly, under all sorts of names. Don’t trust my summary, though – read his.
BSDNow 143 has the usual roundup of news, plus a conversation with Matthew Macy about graphics improvements in FreeBSD.
We need DragonFly people interviewed, since DragonFly graphics improvements have been leading the pack, so to speak. I’m linking to the Jupiter Broadcasting site again since I don’t see this episode up on the BSDNow site yet.
karu.pruun managed to get xwayland working on DragonFly, and also took notes while doing it. That means you can try it out, too.
BSDNow 142 is out. You might think the title is about Perl, the language, on BSD, but it’s because there’s an interview with FreeBSD developer Alfred Perlstein. I’m sure he gets that a lot. Among the other news on the episode is a note about ordering BSDNow shirts: do it today because it’s the last day they will be available! Also, you can order now and pick it up at BSDCan if you’re going to be there.
(I’m linking to the jupiterbroadcasting site because the bsdnow.tv site isn’t updated as of this writing.)
The May issue of BSD Magazine is available now. There’s articles on ZFS, OpenBSD’s arc4random, an interview of Fernando Rodríguez of KeepCoding, and more. It’s a free PDF download if you didn’t know.
If you are on the Skylake series of processors, and also running xorg on DragonFly, pick ‘uxa’ video acceleration. Andrew Slaughter found this made a significant different in visual quality.
Sepherosa Ziehau posted an extended description of his work with nginx on DragonFly, and the kind of performance he was able to wring out of it. Of special note: he posts all his sysctl changes, which might be useful to anyone else in high-traffic environments, and notes that he was able to saturate a 10Gb link with one DragonFly machine.
Also: a followup comparing interrupt vs. polling performance.
Tomohiro Kusumi has been working on a port of autofs to DragonFly. If you aren’t familiar with it, autofs is an automatic file system mounter, so when you access a network file system at its local mount point, autofs kicks in and makes sure the remote file system is automatically mounted. He has an initial report on his progress, and expects it to be in DragonFly master in the next month.
NYCBUG is meeting tonight, and Thomas Levine will be there to talk about Urchin, a shell-based test framework. The announcement also has future meeting/speaker dates noted.
If you’re on DragonFly, or maybe even if you aren’t, and you are using NFS, here’s some tips on how to wring the best performance out of it.
