mikas blog

I am considering to change my writings from english to german in my weblog. But I am not sure whether I should. Any pros and cons?

Due to the fact that I received more and more spammails in my personal inbox in the last few days (even spamassassin and some procmail-rules couldn’t catch them) and because the schema is always the same I created a new procmail-rule:

:0 BD
* http://www.(affiliatedrugs)|(moderndrugstore).biz
{
  :0 fwh
  | formail -i "X-Caught-by: biz-spam"
  :0  
  $MAILDIR/spam_drugstore/
}

Sunday evening/night is spamming-time – but today I am really prepared ;o).

70% of network traffic is produced by IPX! 497 IPX-packets within 3 minutes doing nothing related to networking on the box. Argl!

FreeSBI (version 1.0) is FreeBSD as a live system on CD (like Knoppix). On 2nd March I copied the FreeSBIE-ISO to the TUG-ftp-server and today I plugged in the CD to the CD-ROM of one of the many computers at work ;-)

A windows-like desktop (XFCE) welcomes the user running xinit. The italian menu is a little bit strange ;-) (FreeSBIE is developed by an italian BSD-usergroup called GUFI), but the software works as it should and FreeSBIE is definitely nice for people who want try running a BSD-system.

I am at home again since one hour past midnight. Chemnitzer LinuxTag was really great and together with Thorsten and Jimmy it was fun :-). I’ll write a (german) report in the next few days. Mails, newsgroups, university, work and projects are calling for me ;-)

Update: The (german) CLT2004-Report is online:

2nd Update: Webgallery is online:

CLT 2004 is going to start tomorrow. Today I will go to a “Ausstands-Feier” (some special kind of party ;)) and tommorow we (Jimmy, Thorsten and me) will drive to Chemnitz by car early in the morning. So I should prepare my baggage now :)

Today I tried to check out rrdtool. It’s quite powerful but it’s documentation sucks IMO and using it is quite painful, at least for beginners. I wrote a small shellscript which automatizes some stuff and writes a html-file.

Konq Rellinks is a very nice addon for konqueror, you can use document relations with this plugin in konqueror as in opera and mozilla. Due to that Kevin Krammer is one of the developer of the program he was the one who pointed my to it :-) Have a look at it: screenshot

Today I am really tired. Yesterday I went to bed at around 2 o’clock because of Security Treff Graz. First of all I felt asleep in a very boring softskills-lecture at university, profile-migration on the windows-box (from local to serverside) at work was really ###censored###. The only ray of hope was the lecturer of “control systems I” Nicolaos Dourdoumas who has made a really exciting lecture. Now I will try to go continue on my lectures for GLT04, I hope I don’t sleep in front of my laptop ;o). BTW: On Saturday I am going to drive to Chemnitzer LinuxTag 2004.

Today I installed the dvorak keyboard layout on my happy hacking keyboard, and I am feeling like a small boy who has never seen a keyboard in his life before :-) but I am getting faster and faster. Of course I am using a special Xmodmap. Check out the abcd-dvorak-tutorial (thanks for the URL Thomas Quaritsch!).

As I’ve said some days ago I want to set up ipv6 at home. Now I am running an ipv6-tunnel on my workstation via freenet6.net. I had to change tspc host_type to “router” in /etc/freenet6-client/tspc.conf and due to a bug in the freenet-client I had to restart the tunnel with if_tunnel=sit0 and again with sit1. But now it works like a charme (thanks ak!):

In centericq 4.9.10 german umlauts don’t work for many people, also my box had problems. Now I could figure out (with a hint of Marc Thoben – thx!) the problem. Have a look at my mail to the centericq-mailinglist. Short version: don’t use POSIX for LC/locale-settings but use something like that:

[mika@grml: ~]% locale
LANG=de_AT@euro
LC_CTYPE=de_AT
LC_NUMERIC="de_AT@euro"
LC_TIME="de_AT@euro"
LC_COLLATE="de_AT@euro"

As you might have mentioned I really like the firewire-stuff on linux, today I captured 5GiB of movies – sucessful and on my workstation :). But due to some problems with the dv1394-module (which couldn’t be loaded via insmod after compiling) I wanted to upgrade from kernel 2.6.2 to 2.6.3. I already tried 2.6.3-rc2 but also on 2.6.3 the problem with the e1000-module still exists – my box freezes when there’s traffic on eth0 :-(. But I should move this rant to category linux because all needed stuff works on my 2.6.2, even 3D-support for my ATI Radeon 9600 (benchmark started while watching tv with my WinTV Express):

[mika@grml: ~]% glxgears 
7426 frames in 5.0 seconds = 1485.200 FPS
8916 frames in 5.0 seconds = 1783.200 FPS

No, at home I don’t use KDE 3.2 as a desktop environment due to pekwm is really great ;-), but I configured kicker (the KDE-taskbar) and I really like it because it has some really nice features as kweather (weather reports), klipper (clipboard-manager), kdict (a dictionary, I am using it with dict.tugraz.at), the color picker and the sound-mixer. I found a bug in kweather and reported it. Have a look at my workplace.

As I already wrote firewire works really great with linux. Today I created 124MiB of divx-movies with kino and mencoder:

[mika@tweety: ~/Video]% mencoder -ovc divx4 -o stuff.avi -oac lavc export014.dv

Works like a charme – just the filesize-limit of my system as user mika sucked:

[mika@tweety: ~/Video]% limit | grep filesize
filesize        244MB
[mika@tweety: ~/Video]%

Some days ago I installed KDE 3.2 on the computer of my girlfriend. Today I installed KDE 3.2 on my box at work and I really enjoy it. It’s fast enough for my system, it’s definitive an eye candy, the kicker-applets (klipper, dictionary, knewsticker, kmix, kscd, kweather and so on) are useful, the KDE Wallet Manager seems to be great, Konqueror has much improved Tab-Handling and kontact (the groupware client) seems to be a really good replacement for some “not-so-well-to-use” software (Outlook, Evolution,…). I really enjoy working with KDE 3.2 at office.

Today my brother gave me the digital videocamera from my father and because we would like to create some movies about our cat Rubeo I tried to use the camera with linux. Some weeks ago I bought a firewire-cable and so I connected the camera with my laptop, loaded the kernelmodules dv1394, ohci1394, raw1394, ieee1394 and started a program called kino. And hey – I just works as it should! Not a single problem and even a first try with mencoder works:

[mika@tweety: ~/tmp]% mencoder -ovc lavc -lavcopts vcodec=mpeg4 -o output.avi -nosound ~/mikasvideo.dv
[mika@tweety: ~/tmp]% ls -lah output.avi
-rw-r--r--    1 mika     mika         3,6M 2004-02-25 23:42 output.avi
[mika@tweety: ~/tmp]%

I am absolutely fascinated by it’s simplicity and now I want to improve my knowledge about the possibilties with mencoder :-)
