There’s new busdma fixes (see man pages) by Sepherosa Ziehau available in his git repo; these will show up after the 2.2 release.
Month: January 2009
Search on the site
There’s a Xapian-powered search function on www.dragonflybsd.org now; it should be easier now to figure out where I shuffled everything.
DCBSDCon 2009: register now
You’ve got about 24 hours left to register for DCBSDCon 2009, which starts in 6 days. You should go, and pick up a DragonFly LiveDVD, among other things.
Do you really have your data?
Reading this Textfiles article about keeping data in “the Internet cloud” and then this one about Google made me think: if the Internet went away, what data would you lose?
Kill a bug today
There is, as of this writing, 245 bugs listed in the DragonFly bug tracker. Simon ‘corecode’ Schubert and other have been doing an excellent job of fixing/cleaning items listed there, but it can always use more input.
If you’ve posted something to bugs@, it’s in the bug tracker. Please, especially if it was fixed, make sure the ticket is closed.
Re-experience the PDP
University videos on How to Program a PDP-11. Watch and feel relieved at how far technology’s come in terms of convenience.
ssh Surprise
Recently noticed: OpenSSH 5.1, which was imported into DragonFly some time ago, reversed the preferred order for host keys from DSA to RSA, which will give you a changed host key warning when logging into a newly updated DragonFly host. If that bugs you, there’s an easy fix.
DCBSDCon: goodies
The most recent DCBSDCon blog post mentions that there will be FreeBSD and OpenBSD goodies for sale at the conference, plus DragonFly media. That’s me; I’m burning a pile of DVDs with a LiveDVD image of DragonFly 2.1, which should be freely available at the convention.
RSS from the website
There’s RSS (and Atom) feeds available from the DragonFly website now – these feeds cover changes to the site, including the former wiki-only content.
Python 2.1 retiring
Python 2.1 is being retired from pkgsrc. In the relatively unlikely chance that this affects you, speak up on one of the pkgsrc mailing lists.
Virtualbox success
DragonFly has been unable to work on VirtualBox for quite some time due to a timer problem. However, the VirtualBox developers have come up with a patch that fixes it. It’s not in the VirtualBox 2.1.2 release, though I assume it’ll be in the next one after that.
Wanted: hardware with a connection
As Simon ‘corecode’ Schubert posted, DragonFly needs a system with a good amount of CPU and a good amount of bandwidth to do bulk pkgsrc builds. I’ve been doing it in several places and we don’t have the right combination of bandwidth and speed in any of them.
Donation of hardware that can later be placed somewhere with extra bandwidth would be helpful, too.
More UNIX flavor
Matching the UNIX history quiz from a few posts ago, George Rosamond sent along a note about this NYCBUG talk from Issac Levy on “The Real UNIX Tradition”, which is conveniently available in audio form.
New www.dragonflybsd.org
Assuming your DNS has caught up, www.dragonflybsd.org has been updated using ikiwiki to merge the wiki and the regular site.
Everything that was in the wiki is now present in the Documentation area, and can be edited in the same way. Enjoy! Please tell me if you encounter problems, especially as this is my fault.
DCBSDCon: Fracking, registration
Now this is a convention idea I can get behind: DCBSDCon will have a Frack Room, with Quake-series games and bzflag running. Or, you could work with others to collaborate and debug, but let’s be serious here.
Also! There’s two weeks left to register, and three weeks to the event.
Personal history in ~, Unix history in a quiz
There’s an oldest file meme, first seen here, where you find the oldest files in your home directory and figure out where they came from. The page I linked to uses a Linux-specific search, but some other pages have a scripted way to do it that should work on DragonFly.
I also found a link to a Unix History quiz from the same location, with some answers. It’s a tough quiz.
Git talking
Something I’ve been holding onto for a while and only got around to looking at tonight: A Git introduction at a Google TechTalk, via YouTube.
Anecdote: I saw Randal Schwartz, the speaker, at a Perl conference back in… 2000? He was a decent speaker, and I went up after his talk to tell him how I was (successfully) using two programming practices he specifically deprecated during his talk. Not that it was any better an idea because of that…
Lazy Sunday reading
Want to look at old computer museums? There’s a number of them to choose from. (via) While you’re at it: Apple ][ in a browser, now via Java (via).
In the ridiculously rare event that my old-school credentials are ever challenged, I will just point to my store-bought 5.25" floppy of Castle Wolfenstein for the Apple ][, complete with typewritten label.
Son of Linkpile 2009/01/17
- SysV init must die (via) Someone mentioned runit in IRC the other day, I think...
- V7 Unix for x86 (also via) Put on the bellbottoms.
- This blog has been running various sed and awk one-liner demonstrations, among other things; very useful tricks to remember. Go through the history; there’s fun and useful stuff.
New mirror in Bulgaria
OnlineDirect has a new DragonFly mirror up in Bulgaria; it’s hosting the official ISOs at this point.
Linkpile 2009/01/15
- This Coding Horror article talks about garbage collection and happens to mention an entertaining common BSD function in shutdown.c: die_you_gravy_sucking_pig_dog()
- The DCBSDCon Blog has some notes on the facilities – there will be wireless, and Jason Dixon will be giving his “BSD Is Dying” talk, too.
- An hour of Marshall Kirk McKusick’s FreeBSD kernel class (based on his book) is available now on Youtube. (via) Plus, more videos on other open source topics at the FOSSLC. (via)
- This new column on GameSetWatch, The Amateur, titled “Why You Should Pay for Free“, gets into free software (like BSD) from a giveaway gaming point of view (not like BSD). It’s an interesting take.
- ZangbandTK: Confessions of a Dungeon Hack is a new Rock, Paper, Shotgun article about playing a tiled roguelike, and quite enjoyable to read. Check the comments for some interesting links.
Disc burning made better
Matthew Dillon came up with a patch that seems to fix problems with memory alignment when doing tasks like burning optical media. Try it if you’ve had this problem, or wait, as it will probably be committed soon.
DragonFly vs. EeePC 901
For those of you thinking of installing DragonFly on a EeePC 901, Christopher Rawnsley tried, with some booting problems. Simon ‘corecode’ Schubert has an easy fix, however.
2008Q4 packages, sorta
pkgbox.dragonflybsd.org has a set of packages for pkgsrc 2008Q4 on DragonFly 2.0.1. The bulk build was started after the freeze for 2008Q4 but before the actual branch was released, so it’s not exactly the 2008Q4 release, but it’s pretty close. It’ll be updated as soon as the next build completes. Please, use a mirror as soon as they update.
Less cost for sleep
For those going to DCBSDCon but not yet having rooms to sleep in, a cheaper Days Inn has been found a few metro stops away from the convention.
(Hotel costs kept me from making it to NYCBSDCon, for instance.)
Dmitry vs. ACPI
Dmitry Komissaroffis doing a very useful thing and producing code to support more ACPI stuff – specifically, HPET timers, the mysterious Smart Battery, and Asus systems.
SDHC support?
Hasso Tepper is looking for other people with experience and/or interest in porting FreeBSD’s mmc(4) support for SD cards greater than 2G in size. Contact him is that describes you.
pkgsrc-2008Q4 is out
The 2008Q4 release of pkgsrc is out, with a number of improvements: pulseaudio, OpenOffice 3, and perl 5.10, among other things. The announcement mentions using audit-packages and pkgsurvey, too.
There’s a build of pkgsrc from just before the 2008Q4 ‘freeze’ finishing now on pkgbox.dragonflybsd.org; a build will happen soon. Hasso Tepper noted a higher failure rate in package building for that release…
OpenSSL upgrade, versioning removed
Peter Avalos has committed a new version of OpenSSL – 0.9.8j. (New version caused by a recent security issue.) Also, the vendor branches are no longer versioned, since git has made that unneccesary.
Messylaneous for 01/10
I have a number of items that are all going to get posted together:
- Antonio Huete Jimenez has a binary build of pkgsrc 2008Q3 for DragonFly 2.1.
- Michael Neumann has integrated his “USB stick image integration” code; check the commit message for notes.
- Matthias Schmidt has added IPv6 support to dntpd(8).
Knowing NUMA
Some extra reading: Hasso Tepper posted a link to an article talking about non-uniform memory access (NUMA). Any article that can have diagrams labeled ‘hypercubes’ must be worthwhile.
Google Summer of Code 2009: yes
Google’s planning a Summer of Code again for 2009, according to the still-running mailing lists from last year’s SoC event. More will be announced at FOSDEM.
DragonFly may or may not be participating; it’s dependent on the application process same as every year. If you’re a student, start thinking about what to do, now.
Stick installs now possible
Michael Neumann came up with an interesting script that creates a bootable DragonFly USB drive. This makes it possible to boot up and install on a netbook that lacks a normal CDROM, for instance.
DCBSDCon: books, cons, and threading
The DCBSDCon Blog announces the last 3 speakers at DCBSDCon:George Neville-Neil, one of the authors of The Design and Implementation of the FreeBSD Operating System, Ken Caruso of SchmooCon Labs, and our very own Robert Luciani, talking about DragonFly and threading.
January OSBR out
The January issue of the Open Source Business Resource is out. (via) Dru Lavigne posted a list of the contents, earlier.
Broken, then fixed
The bleeding edge version of DragonFly broke for a short while on Tuesday night. It was quickly fixed; I’m linking to it because Simon ‘corecode’ Schubert’s explanation of his fix is interesting.
What’s happening to ISA
Sascha Wildner posted a clarification: ISA and EISA support in any card will be dropped after the 2.2 release is out.
Registration and PIE for DCBSDCon
The hotel discount for DCBSDCon 2009 expires this Friday, so now is a good time to register. Registrations for the convention itself closes at the end of this month.
Also, Kurt Miller will be talking at DCBSDCon about his work in OpenBSD on Position Independent Executables.
C++ and an argument
Michael Neumann brought up the idea of using C++ in kernel programming, which has been suggested before. Reactions were generally negative, but there would be some possibilities.
pkgsrc state as of 2008Q4
Hasso Tepper posted a note detailing some of the troubles with the recently branched 2008Q4 quarterly pkgsrc release. The 2008Q4 release has some issues on DragonFly 2.o, and some recent changes in DragonFly caused issues, though that’s been patched for now. The result of this is that DragonFly has a ‘soft freeze‘ around end- and mid-year release time for the ABI, to keep problems down.
Better password checking
Peter Avalos has added pam_passwdqc, a simple password quality checker (hence the ‘qc’) to DragonFly.
pcc, again
pcc appears to have had some significant updates due to funding; has anyone tried it on DragonFly recently?
@Play: Cause For Incursion
The newest @Play column talks about yet another roguelike I’ve never heard of: Incursion. (Too much Zangband on my part.) Apparently it follows 3rd edition Dungeons and Dragons rules quite carefully, which is different than the usual vague Tolkienish/D&Dish look that most roguelikes keep. Check the supplement at the bottom for some literary history.
Goodbye, ISA
Are you using any ISA-based network cards? Sepherosa Ziehau is planning to remove support very soon after the 2.2 release; speak up if this is a problem. Or, spend a few dollars and buy a card made in the last 10 years.
BSDTalk 169: me
You get to hear me blather on for 22 minutes about this Digest and how important/easy it is to contribute to BSD projects, in BSDTalk 169.
There are no good old times
If you feel frustrated that big (>100G) solid state disk drives are still relatively expensive, well… It has been much worse. (via)
New partitioning tool
Vincent Stemen posted a note about his homemade tool, called ‘partition’. It has some interesting features, though it would require some documentation and cleanup to use in DragonFly, where it could serve as a replacement for fdisk. If anyone’s interested in making that happen, contact Vincent.
age(4) too
Sepherosa Ziehau has also added age(4) support, a network chip common to Asus systems. Load the kernel module and report your results.
UNIX tidbits
Two UNIX-centric items for end-of-week reading: “The History of Unix *dump programs” and “Roll your own toy UNIX-clone OS“. (via)
All Hammer, all the time
Thanks to Matthias Schmidt, the installer now supports Hammer, meaning you can install an all-Hammer DragonFly system. Well, almost.
Recent BSD crosspollination
Michael Neumann has replaced suser(9) with priv(9), taken from FreeBSD, for fine-grained priviledge control.
Sepherosa Ziehau has added OpenBSD’s in_addprefix() and in_scrubprefix() from OpenBSD, which makes it possible to add two addresses within the same subnet to two separate network interfaces. Read his post for a more descriptive synopsis. Hes also made some original fixes.
He’s also added support (from FreeBSD) for the Atheros AR8121/AR8113/AR8114 PCIe ethernet controller, via ale(4), prompted by some Eee PC 1000H issues that were highlighted here before.
Winter BSDA DVD available
The Winter version of the BSDA courseware DVD is now available. Everything on there is available (in parts) for free over the Internet, but paying the USD$40 for the DVD gets you convenience and a way to support bsdcertification.org. (via)
Even more DCBSDCon speakers
I need to note these faster; they’re piling up: the DCBSDCon blog has announced two more speakers for the convention: Richard Bejtlich (of Tao of Security), who will talking about network security monitoring with FreeBSD, and Marco Peereboom, of OpenBSD, who will be talking about epitome.
