Lazy Reading for 2011/10/30 →
It’s snowing in the northeast U.S., which makes me happy! Keep going, sky!
Richard Stallman’s requirements when giving talks/lectures. (via) I read this not unreasonable but long list and…
Reduced memory usage →
Francois Tigeot does something very useful: he monitors the resource usage on his systems, and tracks how it changes over time. Because of that, he noticed that the recent VM changes in DragonFly…
DragonFly and jails →
Michael Lucas is building jails on DragonFly, and his story of doing so works pretty well as a how-to guide.
GCC updated →
John Marino’s moved GCC from 4.4.6 to 4.4.7, but you’ll have to see the changelog for details. Except it’s so new it isn’t listed… yet.
Got 10G Ethernet? Here’s an improvement →
Sepherosa Ziehau made some changes that led to a 10% and then 20% gain (don’t know if that was cumulative or separate) in network speed for DragonFly. That’s great! It only has a noticeable…
A new Hammer presentation →
Francois Tigeot recently presented a set of slides about Hammer at a recent Irill conference. PDFs of the slides are available at his site, in English and French.
DragonFly and Postgres and testing too →
DragonFly’s now on the BuildFarm list of Postgres test systems. (via Jan Lentfer in IRC)
BSDDay 2011 in Slovakia →
Did you know that there’s a BSDDay 2011 in Bratislava, Slovakia, on November 5th? Well, I do thanks to a random Google search and now you do too. You and I both need to keep watching BSD Events.
Google Code-In for 2011 →
Google’s running the Code-In project again for 2011, where open source projects mentor 13-17-year-olds on a variety of small projects. DragonFly participated last year and had lots of good work…
The next release and what’s needed →
There’s a rare crash in DragonFly 2.10, where applications would segfault. The system would run find. This is apparently more likely to happen in 2.12, though reports on this vary. It’s real,…
BSD Router Project: 1.0 →
I didn’t know this existed, but there it is: the BSD Router Project is a software router, which just reached version 1.0. (via)
Lazy Reading for 2011/10/16 →
I build this up over the course of the week, so I’m never sure what to put here. Does it matter? The meat is the links.
The Binding of Issac. It’s a roguelike, with shooter elements. It’s also…
Bulk build results for 2011Q3 →
I have some pkgsrc-2011Q3 builds done, for x86_64 and i386. I performed them on DragonFly 2.11, but they should work fine for 2.12/2.13. They’re uploading to the pkgsrc-2011Q3 folder on…
MMC/SD cards now automatically supported →
I did not realize this, but MMC/SD cards are not supported in the default DragonFly kernel. Or at least, they weren’t until now. (also committed to 2.12)
Update: PCI-based MMC/SD readers,…
2.12 release candidates →
They aren’t really release candidates per se, just “images I built from the 2.12 branch”, but they are available for testing.
2.12 right around the corner →
There’s only two commits, already in DragonFly-current, to add to 2.12 before it’s clear of all listed release requirements. And maybe binary package builds… which I’m about 2/3 of the way…
Summer of Code 2011 shirts arriving →
I got mine the other day, and here’s someone else’s.
GEM/KMS warning →
Some newer laptops have Intel integrated video chipsets that require GEM/KMS to work well; they are supported by the vesa driver in X, but performance isn’t great. Johannes Hofmann found this out…
pkgin 0.5 changes →
Among other changes to pkgin 0.5 (available in pkgsrc-wip but not pkgsrc-2011Q3), it now notices if you need a newer pkg_install because you’ve shifted to a more recent quarterly release of…
Lazy Reading for 2011/10/09 →
Getting close to 2.12 release…
Steam and Team Fortress 2 running on a BSD – PC-BSD with an NVIDIA driver, in this case, but it may apply to other cards and other games. Using Wine is always so…
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…
