The latest @Play column, “A Date With Asuka“, covers an unlicensed Japan-only roguelike in 3D for the Dreamcast. I had to think about that sentence very carefully in order to type it; @Play is seeking out more esoteric roguelike variants than I thought possible.
This article about how to not treat project contributors reminds me: have you contributed to DragonFly? (and I don’t mean as a committer) Make sure your name is on the Team page.
The 2.4 release will attach disk drives by serial number. Matthew Dillon’s written up a quick HOWTO that describes how to use it. The interesting effect, as he notes, is that a drive can be attached in almost any way – a firewire enclosure, directly to the motherboard, through a card, etc. – and the machine will still happily boot without any changes needed.
For those of you running DragonFly 2.3.1 or later, I’ve updated the pkgsrc-2009Q2 packages on avalon.dragonflybsd.org to the latest versions on that branch. If you’re curious to see which were updated, I have a list after the cut:
It’s now possible to set up rules for your dynamic device file system. If this intrigues you, and it should, there’s more details about the rules within the devfsctl(8) man page.
There’s now a counter in the sidebar to this site (look under my email address) that shows how many posts have been made, ever. Not necessarily helpful for you, the reader, but it makes me feel good.
Also, all those posts, back to 2003, are reachable via the archive page.
Simon ‘corecode’ Schubert has removed GCC 3.4 and Kerberos 5/Heimdal from the base system. Kerberos hasn’t been building as part of base for a while, and is available in pkgsrc. It was also the last item that requires GCC 3.4, so buildworlds are little quicker now. (Cross your fingers that GCC 4.2 the current version doesn’t break somehow.)
ÆrieBSD; a fork from OpenBSD. (via) It appears to be GNU-free.
Update: Steven Rosenberg has some further research.
BSD Magazine’s 3 previous issues are all available for download. If you like what you see, please subscribe. (via)
If you have any remaining issues for DragonFly that you want fixed before the 2.4 release in September, link them to the ‘umbrella issue‘ in the bug tracker. It makes them easier to find.
As predicted, size_t and ssize_t is back to normal. (Hasso already noted this in a reply to the original post.)
Matthew Dillon’s made some changes to Hammer that make performance during mixed operations (reading and writing requests at the same time) much faster. This should work for everyone, though AHCI/SILI/SCSI users will notice it more. The new writing system is called ‘BIOQ‘.
www.dragonflybsd.org is now running a newer version of ikiwiki because of me; tell me if you see problems, as they’re probably my fault. Oh, and I cleaned up the developer docs page too.
Matthew Dillon’s made some improvements to Hammer’s read and write processes. To quantize this, he’s tested Hammer and UFS with blogbench and written up the results. The tl;dr summary: UFS performs well until the system cache runs out, and then it halts. Hammer has some overhead from saving all history, but doesn’t stop working under a much heavier load.
DragonFly’s size_t and ssize_t have been modified. This creates more exact warnings of 64-bit problems when building on 32-bit systems. It may cause trouble with pkgsrc, though, so it will be reverted before the release (on 32-bit) if needed.
Be careful if you’re running bleeding-edge DragonFly. A full buildworld is needed because of this.
I’ve got a number of little items, so more roundup:
- How much disruption happened in DragonFly after introducing a dynamic device system? Surprisingly, very little, as most of pkgsrc still builds. Thanks are due to Hasso Tepper for the corrective work.
- _why makes some very perceptive comments.
- Jordan Gordeev’s been working on the very difficult AMD64 port as part of his Summer of Code work. He says thanks for the help, and others reply in kind. Speaking of which, it’s possible to boot 64-bit DragonFly now, though it’s not production-ready.
I’ve always had trouble updating certain pkgsrc packages that happen to also form the basic tools for pkgsrc – pkg_install, bootstrap, etc. Hasso Tepper has very kindly written up a note describing how to update these packages with newer versions of pkgsrc.
The mpt(4) driver has been updated, thanks to Alexander Polakov. This is useful for anyone using LSI Logic hardware for fibre channel disks, for instance.
Vinum’s been changed to work with devfs, with the advantage that drive labels instead of device paths can now be used. There’s some caveats – read the message for details.
audio/cdparanoia, in pkgsrc, had a major update and now doesn’t work on DragonFly. Hasso Tepper could use a hand fixing it – any takers?
