Yay!
What will you have: tea or chai? Mapping out all the names for tea around the world. I love etymology and tea, and I know there’s some tea drinkers reading… (via)
Speaking of tea, this London universal tea device sounds awesome. (via)

When is DragonFly 3.2 coming out?
Probably not for a few weeks, at least.
pkgsrc freeze for 2012Q3 starts tomor...
As seen in this pkgsrc-users@ post from Thomas Klausner, the freeze for pkgsrc-2012Q3 starts on Sunday and continues for (probably) two weeks before the release.
NYCBUG, RSS, and SMPng
NYCBUG, the NY BSD user’s group, has an RSS feed for their speaker events, found via Dru Lavigne’s always useful BSD Events twitter. The next event at the start of October is a talk about SMPng in FreeBSD. Given that it was the project that in part led to the creation of DragonFly, I’d like to hear about (Read more...)
Do you have offline Hammer1 slave sys...
If you do, they don’t get cleaned up during the normal ‘hammer cleanup’ nightly routine. Chris Turner has added a way to manually specify them as a cleanup target.
I’m pretty sure in this case ‘offline’ means ‘nothing streaming to it from a master disk’. I think.
A potential new pkgsrc site
If you look at new.pkgsrc.org, you will see what may become a new site. This is apparently a test, so don’t react as if this was the actual site.
Experimental pmap optimizations
Matthew Dillon has created an experiment: shared page table mappings. It’s controlled by a sysctl, since it’s still experimental. The real-world effect is reducing the number of memory faults as a process uses up memory, and decreasing the overall memory usage. The obvious benchmark is Postgres speed; this makes the initial exp [...]
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.
BSDTalk interview with David Gwynne
BSDTalk has posted a 30 minute interview with David Gwynne (dlg@). Topics include RAID drivers, SCSI, and networking.
Listen to the interview here: http://bsdtalk.blogspot.com/2012/09/bsdtalk219-david-gwynne.html
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.
