rxvt-unicode and ISO 14755 mode

blog@wilmer.gaast.net (Wilmer van der Gaast) — Thu, 11 Oct 2007 10:22:08 +0200

Now that my (and pretty much every other) machine uses UTF-8 by default, I was pretty much forced to ditch rxvt in favour of rxvt-unicode. Unfortunately the rxvt-unicode authors think attaching some keycap picture insert mode to the Ctrl-Shift key combination (which is easy to hit by accident) would be HANDY. Even handier, it can only be disabled at compile time.

Thanks for nothing guys, I really hope there's at least one person on this planet who agrees that this is handy ... I'm afraid most people who accidentally hit Ctrl-Shift every few minutes don't agree.

So, behold:

CODE:

wilmer@ruby:~/bin$ cat fix-rxvt.sh
#!/bin/sh -ex
cd `mktemp -d /tmp/rxvt.XXXXXX`
apt-get source rxvt-unicode
sudo apt-get build-dep rxvt-unicode
cd rxvt-unicode-*/
perl -pi -e 's/--enable-iso14755/--disable-iso14755/g' debian/rules
dch -n 'ISO 14755/Keycap mode SUCKS!!!'
fakeroot debian/rules binary
sudo dpkg -i ../rxvt-unicode-lite*deb

For all you Debian+rxvt-unicode users out there waiting for this bug to be fixed... :-)

[edit]Added dch command to make sure apt-get doesn't reinstall the original package every time.[/edit]

Intel X.org driver, PAL TV-Out, colours please!

Got a little bit confused by this bug report while trying to get the TV-out on my mainboard working properly. As any European TV, mine wants PAL signals, not NTSC. The bug report gave me the impression that there should be separate PAL/NTSC mode definitions. But in the current driver, this isn't the case anymore.

Instead, they now use RandR properties to maintain this setting. And RandR, at least for properties, seems to be read-only .... soooo, how does it work then???

Well, try something like this:

CODE:

Section "Monitor"
Identifier "TV"
Option "TV Format" "PAL"
EndSection

Took me a whole weekend to find this, but at least it works now, in full colour! This didn't seem to be very well-documented to me, so I hope this post will help. If it doesn't work for you, maybe your TV doesn't understand S-Video. There's a very simple hack to solve that issue too. All you need is two wires, no need to solder anything. :-)

Dear Intel,

Thanks for making Linux drivers for the on-board graphics stuff on my mainboard. Next year, could you please not publish them as a .... .EXE file???

I hate trees!

There are two things in nature here that I don't like. The ever-strong wind that slows me down when I cycle to work ... and trees! I bought this radio-controlled airplane yesterday and went to the park to try it out. The flight went very well thanks to some help from ... well, the wind. The result?

(Try to find it on the big picture, it's not too easy. :-))

Something I really do like here is World Market, though. They actually sell this candy we call "drop" in .nl, and it tastes pretty good:

I just wonder why the German pack says "katjes" instead of "kätzes" or something like that. And there are fishes inside, not cats. They're pretty tasty though, so I don't care.

Work is still going well, my main mission for during my stay here is done. I got two more weeks here before I have to go back to Dublin, so that's well in time. It'll be nice to be back in Europe, at last...

In other news, worked on BitlBee a bit more again in the last few weeks. Worked on the API a bit, so the next time someone says porting Gaim modules to BitlBee is easy, please don't listen. It's a lie. ;-) And there's basic support for Jabber chatrooms now! Just for the non-anonymous ones, unfortunately. (And the majority of Jabber rooms I know of are anonymous.) Will work on that support later, unfortunately it'll be very complicated and hackish.

And this weekend, besides "dropjes", I'm enjoying eye candy from Beryl on Ubunty Feisty. Wobbly windows and all the other stuff. Hey, I wanted some of my OS X eye candy back, okay? ;-)

Oh yes, blog!

Just back from a short trip to Belgrade, and now I'm in the last days of my current job. As I could expect, time is running out, and there's always more to do than I thought, also thanks to having some "bad luck" with the only server with only one hard drive (yes, I know RAID != backup) and broken backup software. Suddenly it turns out that debugfs is not quite the best data recovery tool after all. ;-)

Meanwhile preparations for Dublin started. Looks like I'll go there on the 17th of January already to spend the rest of that week on an introduction tour through the city and another day for looking at some houses that might be good for me.

Meanwhile I didn't have too much time for hacking. The new BitlBee Jabber module isn't completely finished yet, I'm afraid. Would be nice to find some time for it soon...

Oh yes, and the following quote is making me a bit nervous: "All systems administrators have their horror stories. For me, it was setting up a HP Color Bubblejet under Linux using ghostscript before linuxprinting.org was alive. Well that was a piece of cake compared to what I am about to describe in this document."

I know how terrible the Linux printing hell is, so maybe I should go for Maildir after all... ;-) Oh yes, I found that quote in the Cyrus README.Debian, the original source is: "Hosting email for virtual domains using Postfix and Cyrus" (Haim Dimermanas, 2001-08-01)

.deb files are ar archives, but ...

blog@wilmer.gaast.net (Wilmer van der Gaast) — Mon, 06 Nov 2006 22:39:22 +0100

Just to express my frustration of the day a bit. I want the left column to be higher than the right one here. ;-)

From time to time you hear people boasting that they can use standard tools to handle .deb archives. "ar x blablah_0.123-4_z80.deb" and you get two standard tar.gz files to play with. That's indeed convenient, more convenient than rpm2cpio.

However, just try, on a Linux system, to convert those two tarballs (and the debian-binary file, of course) back to a .deb. "ar cr blablah_0.123-4.1_z80.deb debian-binary control.tar.gz data.tar.gz" will do, right? Try to install it using dpkg... Yes, it works! But then, try to put it in your apt repository!

{{ pool/main:
E: This is not a valid DEB archive, missing 'debian-binary' member
E: Errors apply to file 'iso/pool/main/b/base-installer/base-installer_1.42ubuntu12_amd64.udeb'}}

Turns out that there are multiple ar formats and that Debian uses a very simple format and doesn't (fully) support the ar files produced by GNU ar. It's quite confusing that dpkg does support these files while apt does not. Some consistency (or at least packaging a version of ar that is compatible with apt) would be nice, guys.

Anyway, to not be too negative in this post: debian-installer is pretty cool, once you understand the internals a little bit. I just spent a couple of days now on customizing an USB stick installation image, and I think I understand the system at least for a few percents by now. ;-) Have to find the limits of what can be done with preseeding files now. Having fun!

... What ... if anyone reads this? Dunno. :-P
