Hello, government! →
I noticed some slowness when reaching this server, this morning. Logging in, there was no heavy CPU or swap usage. Looking at netstat, I saw the reason: the Department of Homeland Security was…

More REDO →
That didn’t take long: Matthew Dillon has an update on his REDO work; he’s about halfway there. His summary includes instructions on how to test this new work, including ways to change how Hammer…
Huge cleanup for games →
Recently, Sascha Wildner committed a huge number of changes to the various games, bringing them in line with what’s on NetBSD and style(9). This was all put together by Ulrich Spoerlein.
I draw…
Interest in tmpfs, again →
Antonio Huete Jimenez wants to find anyone working on tmpfs for DragonFly; his post about it summarizes the work so far. He’s interested in working on it, in any case.
Hammer REDO and other storage notes →
Matthew Dillon declared his intention to have REDO working for Hammer very soon. This will improve speed by lowering the number of fsync()s needed in a given period of time to flush data to disk.
BSDTalk 184: Matthew Dillon and DragonFly →
Why, BSDTalk 184 is our very own Matthew Dillon talking about all the recent changes in DragonFly, for a good half-hour! I’ve listened to about half of it so far… I hadn’t realized the…
OpenSSL and also DNSSEC →
Jan Lentfer’s posted the steps to test OpenSSL encryption – I link to them because it’s interesting to see the steps spelled out.
Jan’s also posted a patch to enable DNSSEC support throughout…
Fix for common libc problem →
There’s a recent libc vulnerability that appears to be present in every BSD and Linux flavor. (Nearly every? There’s a lot…) Antonio Huete Jimenez committed the fix, with instructions on how to
Hammer downgrade and upgrade bug →
Thomas Nikolajsen experienced firsthand a bug where downgrading a Hammer PFS master to a slave and then later making it a master again lost all data. Lucky him… The problem’s now fixed.
Too much ram: it’s possible →
I’ve always said you can’t be too rich, too thin, or have too much RAM. (I’m paraphrasing a quote from the Dutchess of Windsor.) However, maybe you can have too much RAM. Recent changes by Matthew…
vr(4) driver fixup →
Jan Lentfer noticed a lot of errors with his vr(4) card under load. Matthew Dillon suggested some reasons/fixes, and then made a commit that may fix it. Please test if you have an older…
dragonflybsd.org fixed →
There were some errors with the dragonflybsd.org domain, which are now fixed. This includes some issues in NNTP access to the discussion groups, which is why I don’t have a link for this.
MPSAFE details →
In response to a question about fine-grained vs. coarse locking, Matthew Dillon detailed the locking types used by DragonFly and the remaining work left to make the system able to function…
Bleeding edge made less sharp →
As previously noted, some of Matthew Dillon’s work was potentially destabilizing. The “danger period” (I saw no issues reported) is over.
cryptodev support added →
Jan Lentfer has added cryptodev support in openssl. What does that mean? It means that separate encryption hardware can be used to offload the computation needed to encrypt data for OpenSSL….
Update for spamassassin →
This has been bouncing around other news outlets, but I’ll mention it here: There’s an out of data SpamAssassin rule that can potentially mark mail as spam because of the 2010 date. A mail to…
OSBR: Success factors →
The January issue of the Open Source Business Resource is out, with the topic being “success factors”. Many of the articles focus on participation, and it’s an interesting read. February’s theme…

Messylaneous for 2009/12/30 →
It’s New Year’s Eve Eve, and so here are a bunch of links I’ve built up over the past few days.
Hubert Feyrer posted notes on how to mount fixed disks in KDE. This probably works on NetBSD, but…
4k disk sector support →
Newer disks are moving to 4KB sectors (more info), instead of the 512-byte sectors that have been in use for… decades? There’s been some recent discussion on how to support this, for…
