Do you have an ixbge(4)?
If you are using an Intel 10G Ethernet card with a 82598GB chipset, you’re using ixgbe(4). You may want to set the net.inet.tcp.sosend_agglim sysctl to a value over 12 in certain circumstances, as described by Francois Tigeot.
Some new Hammer features: scoreboards...
These are small, but they make life easier: Hammer now has a scoreboard file, for viewing of mirror-streams running in the background. There’s also a ssh-remote directive, so you can use ssh without enabling an interactive shell, and a HAMMER_RSH environment variable so different remote shells can be used. These are all for Hammer 1.
A lot of scheduler talk
If you ever wanted to read an extensive discussion about the scheduler, today’s your day. Mihai Carabas, who posted the details of a long discussion he had with Matthew Dillon about how the scheduler works. You may recall Mihai’s name from the very successful GSoC scheduler project that recently finished.
(look, a link to the ne [...]
Mailman conversion for DragonFly mail...
All the mailing lists at @dragonflybsd.org have been converted over to Mailman. The old archives are still functioning, and will continue to update until I can find enough old material to retroactively complete the Mailman archives.

Whee!
deadweight, “Find unused CSS selectors by scraping your HTML”. I’ve needed something like this for years. (via)
The same sort of thing for pkgsrc: pkg_leaves. Worth running at least yearly, or at least before any significant pkgsrc upgrade. There’s no point in updating a package you don’t use or need.

Mailman conversion for dragonflybsd.o...
If you’re on any of the dragonflybsd.org mailing lists, I’m converting them over from bestserv to Mailman. I’ve done bugs@, commits@, hammer@, and test@ so far, and I’ll move the old archives over to the same format as soon as I find an actual mbox file with the old messages in it. The remaining lists should be tomor [...]
A whole bunch of installation notes
DragonFly user varialus has created a page on the DragonFly website (it’s a wiki, after all) with all the notes taken from trying installation, etc. There’s far more notes than I expected there, so it’s worth a read.
Porting drivers, for future reference
Much of this new document has been around in other forms for a while, but now, there’s a brief guide on porting drivers to DragonFly in the source tree.
LOPSA call for papers
LOPSA East is happening next May in New Jersey. I haven’t seen mention of this on any BSD list, but there’s definitely Unixy things happening there. The call for papers is out.
BSD Magazine for Sept. 2012
The September issue of BSD Magazine is out, as a free PDF as usual. Visit the site to find out the table of contents.
BSDTalk 219: David Gwynne and OpenBSD
David Gwynne talks for 31 minutes about OpenBSD on BSDTalk 219. Also, Will Backman, the host of BSDTalk is heading to Tbilisi, Georgia next month. Say ‘hi’ if you’re a Georgian.
Some more books to read
This recent question asked on-list about creating your own file system meandered into good reference books. This so far was “The Design and Implementation of the FreeBSD Operating System“, “Modern Operating Systems“, and the paper “Vnodes: An Architecture for Multiple File System Types in Sun UNIX“. Looki [...]
NYCBUG, Adrian Chadd, and teeny tiny ...
Adrian Chadd has apparently been smushing FreeBSD onto MIPS systems for some time, and he’s going to talk about it tomorrow night at the NYCBUG meeting. I’m noting it because I’ve always found it interesting how much can be stripped out of a kernel and userland and still have a functional system.
BSDMag, collected
BSD Magazine has a “Best of 2011″ issue out for purchase; it has updated versions of various articles published over the last year in BSD Magazine. The price is not clear on the website.

I hope you like your links eclectic this week.
DragonFly is a popular project name, but this is unrelated to DragonFly BSD.
Russian Tea HOWTO. I know there’s at least a few vigorous tea-drinkers in DragonFly other than me. The tl;dr version is “make a syrup and dilute”, but it’s more enjoyable to get into the paperp [...]
Do you have a SSD yet?
Because here’s some recommendations on good models, and here’s a way to check SSD health. Seriously, they’re great.
3.0.3 images up
I’ve uploaded DragonFly 3.0.3 disk images, both ISO and IMG. They should start appearing on a mirror site near you in the next 24 hours. This took a while after the tagging, I know, but I wanted to make sure every one of them booted. I didn’t on a previous release, and regretted it.
LSI users, take note
If you have a LSI RAID card, meaning you are using the mfi(4) driver, Sascha Wildner has added /proc/devices to linprocfs, so that LSI’s MegaCLI configuration utility will run.
Is your battery smart?
Sascha Wildner has pushed smart battery support, based on a patch from Dmitry Komissaroff and FreeBSD. He asks people to try it out. It apparently provides for more accurate battery charge level readings?
Postgres benchmarking again
Francois Tigeot benchmarked several different operating systems using Postgres 9.2b3, including DragonFly, and published the results. I have a local copy of the PDF since the attachment didn’t really survive the archiving. Follow the thread for discussion. The Linux results look abnormally high, so it is possible that something diffe [...]
