NFS fixes, too

Justin Sherrill — Mon, 26 Dec 2011 19:36:05 +0000

Since I’m already talking about imports, several changes from FreeBSD and OpenBSD for NFS, plus more original material, have been brought in by Venkatesh Srinivas. Those changes from FreeBSD apparently improve NFS write performance, though I don’t have numbers to show.

Future changes for PF and ALTQ

Justin Sherrill — Sat, 10 Sep 2011 22:55:20 +0000

The recent OpenBSD 5.0 pre-release announcement on undeadly notes that ALTQ is being replaced by new priority settings. This should make it to DragonFly at some point, since pf in DragonFly has been catching up to the current version of pf in OpenBSD, thanks to the efforts of Jan Lentfer…

Lazy Reading for 2011/08/28

Justin Sherrill — Sun, 28 Aug 2011 13:31:11 +0000

This week has taught me one thing for sure: Always make sure your backup generator is working. And over-plan battery capacity. That’s actually two things, but what the heck. I’m tired, for reasons that can probably be inferred! I’m not the only one suffering these problems, it seems.

There is a certain subset of readers here that will find this fascinating: a video of a game postmortem. Specifically, Elite. (via) Needs Flash.
This is as good an article as any I’ve seen describing where the tablet computer market is going, at The Economist.
Remember RetroBSD, mentioned here previously? Here’s some discussion of it.
EuroBSDCon’s 2011 conference is open for registration, but the early bird discount only lasts until the end of August, so jump on it soon if you’re thinking of going. It’s the 10th anniversary of the event!
PHP 5.3 is coming to pkgsrc as default, soon? The PHP 5.2 -> 5.3 transition seems to mess up a lot of code because of some changes in the way things are handled, or at least that’s my experience, so watch out.
Make sure you aren’t running mod_deflate on your Apache 2.x server.
Kristaps Dzonsons, the fellow behind mdocml (which is in DragonFly now and mentioned here before) is working on a mdoc manual. It’s an actual book, with examples. It’s titled “Practical UNIX Manuals: mdoc”, which sounds like part of a series, though I don’t know if there’s anything else. I’d sure like it if there was. (via Undeadly.) Look very closely at the mdoc web page and you will see the markup, too. Neat!
Breakout treated as a musical instrument, in 1983. That’s too glib a summary of this explanation of an old book studying the game Breakout and playing it. Really, read the article, and remember that the book described would just be lost in a sea of ~~blog posts~~ noise today. (via)

Your unrelated comic link of the week: Wonderella. This is the comic that ruined Batman for me. I can’t unthink it.

pcc near 1.0; try on DragonFly?

Justin Sherrill — Thu, 24 Feb 2011 03:57:39 +0000

The pcc compiler is nearing 1.0. (via) This is seen as a gcc alternative, and it’s present in NetBSD/OpenBSD. I recall it didn’t work for DragonFly because of a lack of TLS support… Might be different now, if anyone wants to try. (see prior mentions on the Digest)

Lazy Reading: down memory lane

Justin Sherrill — Sun, 30 Jan 2011 18:50:50 +0000

Entertainment, this week. There’s several items here that will be more entertaining if you’re over 25. Or maybe 35. Get clicking!

If O’Reilly was to publish any of the various parody books out there, it should be this one.
Also, looking for those image links led me to this programming language suggestion. Oh! And that led me to this treat for people who remember Advanced Dungeons and Dragons.
A good game critic talking unabashedly about his love of roguelikes? I am so linking it!
An update on the OpenBSD IPSec backdoor kerfuffle thing.
OK, back to entertainment. A magic number!
Wierd: new NetBSD platform support… from Microsoft.
Huh. Apparently there’s some other meanings for BSD.
Among other things, this article describes some Ruby tests that work so vigorously to make the tests like natural language that they become harder to write. No big story there; I’m sharing my sense of surprise.
BSD: it’s tough. (link fixed) The complaints these people make are valid, though.

NYCBSDCon surplus

Justin Sherrill — Wed, 05 Jan 2011 04:14:48 +0000

Apparently the surplus money from the recent NYCBSDCon is going to each of the BSD projects. Great news! Now, what to do with it…

More pf updates

Justin Sherrill — Thu, 18 Nov 2010 01:18:22 +0000

Jan Lentfer, who apparently has a high tolerance for pain, has now brought the kernel part of pf up to the equivalent of the OpenBSD 4.4 version, available for testing. It’s not yet committed. pfctl’s updated too.

uguru for ABIT for us

Justin Sherrill — Tue, 19 Oct 2010 03:19:36 +0000

Sascha Wildner has added uguru(4), from OpenBSD, to support the microcontroller on ABIT motherboards which report on temperature/fan speed/voltage.

New starting page

Justin Sherrill — Sun, 17 Oct 2010 04:26:55 +0000

Siju George found no equivalent of OpenBSD’s ‘afterboot‘ quick-start page in DragonFly, so he went and created it himself. Go, read.

BSDTalk 200: Kjell Wooding and mg

Justin Sherrill — Wed, 13 Oct 2010 04:02:30 +0000

The 200th (yay!) episode of BSDTalk has 14 minutes of conversation with Kjell Wooding, talking about mg, a sort of teeny emacs included with OpenBSD.

BSDTalk 195: Mike Larkin, ACPI, OpenBSD

Justin Sherrill — Sun, 22 Aug 2010 00:10:31 +0000

BSDTalk has a 19 minute interview with Mike Larkin talking about ACPI and OpenBSD.

Huge packet filter update

Justin Sherrill — Mon, 09 Aug 2010 01:32:37 +0000

Jan Lentfer has updated pf (and pflogd and ftp-proxy) in DragonFly to match what was in OpenBSD 4.1. Why this intermediate step? pf went through a lot of changes after OpenBSD 4.1, so this was easier than jumping right to the current version – which he plans next.

In any case, this was a huge and difficult job, with somewhere around 10,000 lines of code added, and very useful for DragonFly. Jan also managed to keep the DragonFly-specific features working, where “no state” is the default, along with features like fairq.

More mandoc madness

Justin Sherrill — Sat, 17 Jul 2010 01:09:06 +0000

Undeadly has an article up about recent work on mandoc in a mini-hackathon. It’s mentioned in context with OpenBSD in the article, but mandoc is also present in DragonFly, and is a potential groff replacement. (And I think groff is the last item in base requiring C++? I may be wrong.) Plus, as I’ve said before, I like mandoc’s output. It would be nice to use that for our online man pages, for instance.

Messylaneous: Reviews, packaging, installers, etc

Justin Sherrill — Sun, 27 Jun 2010 15:27:39 +0000

Link catchup!

The BSD Certification Group needs reviewers for the BSDA exam objectives. It’s as easy as writing on a wiki.
Undeadly has a lengthy article up about the OpenBSD equivalent of pkgsrc bulk builds, called dbp3. Interesting, because it was constructed on purpose, for that purpose. It’s interesting to me because I have pbulk running all the time, and it’s not as liner a process as I’d like.
The PC-BSD installer is now present in FreeBSD; I think this is based on the same original installer used for DragonFly. Maybe, maybe not, but I’m curious about the feature set if it’s able to displace the venerable and firmly lodged FreeBSD sysinstall.
Off topic: I bought an Android-based phone recently, so this (kinda grody) comment on how Apple handles bad reception for the new iPhone is entertaining.
Really off topic: this man’s conversation about polyhedral dice (Youtube) is strangely compelling. You may or may have needed to play tabletop games previously to really appreciate it. (via)

Mandoc, mdocml, and usage

Justin Sherrill — Sat, 05 Jun 2010 00:29:45 +0000

There’s an interesting article about mandoc and mdocml up on undeadly.org, talking about its history and usage in OpenBSD. It’s present in DragonFly, though it hasn’t been set to replace anything (i.e. groff), yet, that I know of. I do like the mdocml HTML output, and I’d like to see it here.

Potential pf update

Justin Sherrill — Sun, 16 May 2010 03:03:27 +0000

The version of pf in DragonFly is somewhat long in the tooth, but Jan Lentfer’s volunteered himself for the herculanean job of updating it. Go, Jan! Let’s hope this large task is more Nemean than Augean.

Messylaneous for 03/24/2010

Justin Sherrill — Thu, 25 Mar 2010 02:01:29 +0000

In an effort to catch up…

Matthew Dillon made a change to how material in memory is paged out; it may improve things depending on how much paging your system already does.
The AsiaBSDCon OpenBSD papers are online, with mention of video of the presentations.
Use keys for your SSH login, cause this will only get worse.
Ten Shell One-liners. The first one, using your favorite editor on the command line, is one of those things I knew about, but didn’t know to do. (caveat: some Linuxisms)
Want to test a big xorg update for pkgsrc? Of course you do.

Messylaneous for 2009/12/30

Justin Sherrill — Thu, 31 Dec 2009 03:29:05 +0000

It’s New Year’s Eve Eve, and so here are a bunch of links I’ve built up over the past few days.

Hubert Feyrer posted notes on how to mount fixed disks in KDE. This probably works on NetBSD, but I bet it would work on DragonFly too…
pcc is now able to build an OpenBSD i386 kernel. Will it work for other BSDs? I hope so, eventually.
The FreeBSD Foundation is in the last hours of donation for 2009 – give if you get a chance. Did you know they get Bad Code Offsets, like carbon offsets? I did not know such a thing exists, though it makes sense.
Brian Kernighan talking about Elements of Programming Style, in video. (via) Kernighan’s book, “The Practice of Programming“, with Rob Pike, is an excellent read.

Messylaneous for 2009/12/10

Justin Sherrill — Fri, 11 Dec 2009 04:44:37 +0000

I’ve been building this entry up for a while, so some of these entries are newer than others.

From the howling void: OpenSolaris or FreeBSD. I’ll admit I haven’t tried OpenSolaris, but I’m also biased to BSD.
cpdup, originally-on-DragonFly software, has had an update.
This description of the Content Pyramid talks about web content and links, but it could be stretched to open source software. There’s always been an implicit value to being at the top of the pyramid – hence the prestige not always fairly attached to “the commit bit”.
Old computer facts (storage sizes) presented in handy infographic form? Sign me up!
vitunes, a curses-based playlist manager. OpenBSD-specific, but may work on DragonFly. I like the look. (via)
Video4Linux support is being worked on for FreeBSD, as apparently the headers are available without having to accept the GPL. This makes it potentially available to all the BSDs, which is nice.
FreeNAS is moving to Linux, which is a mistake bummer. Except iXsystems stepped in and now FreeNAS is continuing as a FreeBSD-based item. A story that seemed bad but came out well, thanks to iXsystems. (Quick, buy their hardware!)
“If you know of surviving software on 1/2″ tape, paper tape, cards, DECtape, etc. from users groups or computer manufacturers, please contact us. Equipment is available to recover these bits, and in some cases can be brought on-site.” (via)
3 BSD-themed holiday gifts.
what.

hotplugd added

Justin Sherrill — Sat, 05 Dec 2009 01:50:48 +0000

Alexander Polakov has imported OpenBSD’s hotplugd(8). It monitors for hotplug-style events, like disk additions and removals, and executes corresponding scripts to handles those events.
