This weeks’ BSDNow has an interview with Edicarla Andrade & Vinícius Zavam about FreeBSD-powered robots. Yep, robots. There’s other news there too, but it’s not as interesting unless it is about lasers.
Kisumu digital library and DragonFly
There’s a new digital library in Kisumu, Kenya – and it’s running DragonFly for file storage.
Hammer2 major changes
Hammer2 now has inode indexing, which Matthew Dillon was avoiding while trying to create more efficient hardlink support. The result is now with that problem solved, more updates can come in: NFS support, mtime updates, output changes, code removal, and lots of other changes, not all of which I’m even linking.
nvmectl added
If you have a NVMe chipset under DragonFly, you now can use a special utility to retrieve status information: nvmectl. Right now, only ‘info’ is implemented.
garbage[31]: Pirates of the Corebootean
I was traveling and completely missed this, even though it’s on a regular schedule: garbage[31]: Pirates of the Corebootean.
HEADS UP: world reneeds rebuilding
If you are running DragonFly 4.5 (i.e. bleeding edge), Sepherosa Ziehau made an ifnet change that will require a full buildkernel/world if you want things like netstat to keep working.

Reminder: sometimes VESA is better
This is limited to some users of specific Intel video chipsets, but: if you get odd screen artifacts in X, the ‘vesa’ driver may work just fine for you. Or turn acceleration off. Or set ‘drm.i915.enable_execlists=0’ according to zrj on #dragonflybsd.
(Updated to reflect all the answers in the thread and elsewhere.)
BSDNow 147: Release all the things!
BSDNow 147 is available, with an interview of Glen Barber and Peter Wemm. They’re talking about release engineering, as you may have guessed from the title.
Don’t forget tuning(7)
If you didn’t already know about it, you will find this useful: DragonFly has a tuning(7) man page, about getting the best performance from your system. Matthew Dillon recently updated the man page with some tips about SSD setup.
What’s that @@?
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.
DragonFly and Hyper-V
Sepherosa Ziehau needs to run DragonFly under Hyper-V at work, so he’s making improvements .

In Other BSDs for 2016/06/18
If you didn’t already look at it, BSDNow’s summary of BSDCan events is worth going to; it’s complete enough I deliberately left BSDCan links out of here. Undeadly has an OpenBSD-specific summary too.

garbage[30]: Adventures at BSDCan
garbage[30] has BSDCan trip reports, OpenBSD news, and complaints about CVS, among other things. CVS is an easy target but I want to hear it.
When a mouse isn’t a mouse
There are USB devices out there that are sort of like a mouse, as in they work as a pointing device, but they don’t show up as a mouse device. For example, the PowerMate USB Multimedia Controller. It’s possible to pipe the events from this or similar ‘weird’ devices to sysmouse, and use it the way you’d expect, with this fix from user tautology.
BSDNow 146: Music to Beastie’s ears
BSDNow episode 146 is available, with an interview of Hans Petter Selasky about USB and FreeBSD. There’s also a nice collection of links to BSDCan material, including video from the event.
Hammer 2 and CRC
As part of his NVMe work, Matthew Dillon found I/O speed so fast that CRC checking actually got in the way of disk activity. He’s brought in a new CRC algorithm called xxHash. He also brought in Mark Adler’s hardware iscsi_crc32 implementation, but did not add it to Hammer2. There’s some work on read-ahead operations too, to deal with the NVMe throughput.
NYC*BUG Wednesday: HardenedBSD
(Posting earlier than the usual ‘In Other BSDs’ content, because it’s happening tomorrow.)
NYCBUG is meeting tomorrow, June 15 at 18:45 Eastern time. It’ll be at Stone Creek Bar & Lounge, 140 E 27th St. in New York City. The speaker is Shawn Webb, and he’ll be talking about his HardenedBSD work in “Adventures in HardenedBSD”.
