Another ‘quiet’ week – lots of commit activity in the other BSDs, but not a lot to point at directly. PostgreSQL/FreeBSD performance and scalability on a 40-core machine. (PDF link, via) There’s comparison to DragonFly’s results, mentioned here before. DragonFly’s solution of shared page tables is dism [...]
The 44th BSDNow episode is out, with an interview of Craig Rodrigues, a tutorial on creating pre-patched OpenBSD ISOs, and the usual discussion of news items, including DragonFly’s recent pf changes. (I don’t get the pun in the title this time, darnit.)
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! 2014-07-02 - Introduction to Timekeeping, Steven Kreuzer 6:45, about.com (1500 Broadway enter on [...]
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. The History of Mana. (via) Where “Von Neumann architecture” comes from. (via) Futuristic User Interface 16. (video) Floppy table. The storage space is clever. As I’ve said before, every software project grows until it has its own package manager for installing other software. Thi [...]
This week seems relatively quiet; possibly because school is out and the weather in the northern hemisphere is nice? PC-BSD 10.0.0.2, the release, is out. The PC-BSD text installer now supports full-disk encryption. Where KDE is Going, part 1. (via) Another OpenBSD GSoC project summary. procfs in OpenBSD is probably going to be removed (Rea [...]
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 (Rea [...]
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 k [...]
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. Non-classical processor behavior: How doing something can be faster than not doing it. Confusing but interesting. Rudd Canaday’s blog. One of the people behind UNIX, though not as well known. His stories have some very interesting glimpses into early computing. (via) Ergonomic [...]
I have a backlog from stuff I missed last week while traveling, so we all benefit! PC-BSD 10.0.2-RC2 is out. PC-BSD will be at SouthEast LinuxFest. Here’s the roadmap for Lumina, PC-BSD’s new desktop environment. DiscoverBSD’s summary for 2014/06/16. FreeNAS vs. NAS4Free. Didn’t need to be 8 pages. (via) Peter’ [...]
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.
