Matthew Dillon changed the default keep-policy in DragonFly to:
set keep-policy keep state (pickups, sloppy)
This is to match other BSDs (which? I don’t know) and reduce overhead, according to the commit.

A note for everyone: use Hammer default on a very busy filesystem, and you will eat a lot of disk space since all file changes are recorded. (I’ve done this to myself a few times.) Francois Tigeot has a list of tips on how to keep that from happening.
I am pasting the announcement verbatim because NYCBUG is having some hardware issues with their mailing list archive. It’s interesting for both subject matter and because you get to see the inside of about.com. RSVP soon so you can get in!

Abstract
Time is a funny thing. You can spend it, save it, waste it and kill it,
but you can’t change it and there is never any more or less of it.
Everyone knows what it is and uses it every day but no one can seem to
define it.
In this talk I will provide a brief introduction to time, timekeeping,
and the uses of time information, especially in scientific and technical
areas.
The max number of CPUs on DragonFly just went from 63 to 64. This is really just a side effect of preparation to move up that limit, but I am entertained by the single-digit bump.
Are you running a Hammer filesystem on a low-memory system? You may get some warnings. It’s possible to tweak some settings to accommodate it, or just deal.
I bring the audio and the visual today.
You unrelated comics link of the week: The Imitation Game, the story of Alan Turing, written by Jim Ottaviani and illustrated by Leland Purvis. I have other work by both authors – they are excellent – and Alan Turning should be a name already familiar to you.
This week seems relatively quiet; possibly because school is out and the weather in the northern hemisphere is nice?
Predrag Punosevac noticed that turning on pf was slowing his machine down. Rearranging the rules fixed a lot of it for him. However, Matthew Dillon decided it was time to make pf work concurrently instead of in a single thread, and 24 hours later, it does. Quick, someone benchmark this!
BSDNow 043 talks with Marc Espie of OpenBSD about packaging, goes through updating your BSD system (all of them? I haven’t watched yet), and discusses a number of other links.
If you are upgrading a DragonFly 3.6 system to 3.8, make sure you have the absolute latest version of 3.6 first. A few people have had a crash during install of the new initrd, which leaves the system in an unbootable state.
There’s a fix now in 3.6 from Joris Giovannangeli, so updating 3.6 and then moving to 3.8 will ensure this doesn’t happen. He posted a heads-up notice too.
(Why, yes, that is why shiningsilence.com was down for some hours today… With Matthew Dillon and Sascha Wildner’s help, I was able to copy bits of /boot and /usr from a live CD back on disk and get online again.)
Did you try to install DragonFly relatively recently and it never made it past the bootloader? Apparently there’s a bug in some BIOS when using a smaller USB drive to install. The loader checks multiple places for information, and if it checks somewhere that’s ‘farther’ than the end of the disk (i.e. 6G on a 4G USB key), the machine locks up.
Matthew Dillon and Kyle Davis spent a good number of hours figuring this out today, and Matt committed a fix. So, if you were bit by this problem, try a -LATEST image about 24 hours from now and see if it works.
O’Reilly is running a 50% off special on a variety of books on electronics, with coupon code WKECTRC. I’m posting it now because it only lasts for this week.
Update: another offer just popped up in my email – 50% off various “web performance and operations” books with the code CFVLTY4.
BSDDay 2014 is happening August 9th in Argentina, and the call for talks is out – there’s been DragonFly speakers and visitors there before.
Again, a backlog from last week means this week is fat.
Your unrelated links of the week: My side hobby I never mention here is baking. I looked up a word I didn’t know, found out about an ice cream type I’ve never seen, started reading about odd things to do with eggs and pressure cookers, and now I’m confused by the possibilities. No narrative point here; I just need to get in the kitchen.
I have a backlog from stuff I missed last week while traveling, so we all benefit!
Sepherosa Ziehau implemented a UDP echo response tool, which not surprisingly meant he also had some UDP performance improvements. As he points out in the commit, it makes lockless firewall state tables possible.
BSDNow’s 42nd video is up, with an interview of Bryce Chidester and a tutorial on chaining SSH connections.
The dports binary packages built for DragonFly 3.4 are removed. If you have a 3.4 system, you can build from source, or preferably just upgrade. Note that the 3.4 release images are still out there if needed.
I tagged DragonFly 3.6.3, at Sascha Wildner’s suggestion. Why do that when there’s a 3.8.1 out? This way there’s a version of 3.6 that has all the fixes included, including the recent OpenSSL updates. This ‘final versioning’ should probably be done for every release. I’ll work on final images.
The 3.8.1 tag was planned for tonight; I’m waiting to find out if there needs to be a new set of binary ports for 3.8.1 before I tag.
I tagged DragonFly 3.8.1; you can see a list of the changes in the tag message. New images are built. If you are already running 3.8.0, a normal make src-update and rebuild will get you everything.
