Fancy server setup →
User ‘Zenny’ asked questions about setting up a server similar to ones described in this presentation, except using DragonFly and Hammer. Most of it is possible now, going by the thread.
TRIM arrives for DragonFly →
Tim Bisson’s work on TRIM support has been committed. I don’t know if it will show in 2.12, but it’s off by default so it would seem a safe move.
The last MP step →
There’s only one multiprocessing bottleneck left in DragonFly: vm_token. Matthew Dillon’s working on removing it, and he’s been testing his initial results on a 4-core machine and a 48-core machine,…
Performance curve for DragonFly 2.12 →
Samuel Greear has graphed out the performance of both MySQL and Postgres on DragonFly 2.12 as you add threads. There’s a very nice correlation on performance and number of cores. For comparison,…
2.12 change summary →
The 2.12 branching generated a list of every DragonFly commit since 2.10, grouped by committer. Good to browse through. Try to ignore the part where it shows the measly 4 things I did, with poorly…
DragonFly 2.12 branched →
It’s not the 2.12 release yet – just the initial branch of 2.12. This will become the release version of 2.12 in a few weeks.
pkgsrc-2011Q3 is released →
The latest quarterly release of pkgsrc is out. You can download it via CVS, or update /usr/Makefile to pull down the correct branch. I’ll be building binaries as soon as I can. I like the release…
Lazy Reading for 2011/10/02 →
Yep, fall hits and it’s easier to find links.
DragonFly morphology. The insect, not the operating system, though that would make an interesting diagram.
Stick your pinkie in the corner of your…
A whole lot of VM fixes →
Matthew Dillon and Venkatesh Srinivas have committed several fixes for some elusive problems. If you’ve had an unexplained crash, this may keep it from repeating. If you haven’t had a wierd…

OSBR: now it’s TIM →
The Open Source Business Resource, linked here before, has become the Technology Innovation Management Review, or TIM Review. Conveniently, the editor is named Chris, not Tim, so nobody will get…
Potential job available →
A position opened up for a junior systems administrator at my workplace. You have to be willing to live near Rochester, NY, administrate a mix of Windows and unixy machines, do desktop support, and…
More on DragonFly in production →
Michael W. Lucas is setting up two DragonFly machines, to try out Hammer. I linked to his tweet about this in the last Lazy Reading post, but this is a more in-depth explanation of what he’s…
Pkgsrc freeze for 2011Q3 is extended →
The freeze for the next quarterly release of pkgsrc has been extended another week, to October 2nd. This will push the DragonFly 2.12 release out a ways, too.
Lazy Reading for 2011/09/25 →
This week’s Lazy Reading just built itself up quickly; autumn arrives in the northern hemisphere and suddenly a lot more activity starts going on.
9vx, Plan 9 as a user process. (sorta like a…
2.12 Release issue roundup →
I’ve put together a catch-all ticket for remaining issues to fix before the 2.12 release of DragonFly: Issue 2135. Several of the issues have already been dealt with by Peter Avalos and Sepherosa…
OpenSSh update to 5.9p1 →
Peter Avalos has updated OpenSSH to version 5.9p1. This might be the last thing before the next DragonFly release.
Update on the update: he updated OpenSSL (1.0.0e) and file (5.09) too.
Lazy Reading for 2011/09/18 →
I might have a job open at my workplace soon, for a junior admin/support/network role. (Department is too small for narrowly defined roles…) I’ll post about it here if it happens.
libguestfs,…
TCP changes I think →
From what I can tell, Sepherosa Ziehau’s made some changes where you can control TCP timeout and keepalive timing on a per-tcpcb basis, or at least that’s what I gleaned from the docs. He’s…
Summer of Code and DragonFly, 2011 wrapup →
DragonFly had another good year with Google’s Summer of Code program. We had 6 slots, and 5 passed projects. (Irinia, if you’re reading this – where did you go?) This is our 4th year participating…

The ‘freeze’ period (when bugfixes are the only addition) for pkgsrc will start on September 18th, with the next quarterly release of pkgsrc, 2011Q3, scheduled for the 25th. Think of it as an…
