freiesMagazin 02/2011 publishedFebruary 6th, 2011
The journal freiesMagazin just published it’s February issue, describing all the bots that took part in the programming contest.
Those of you that aren’t convinced by this topic, they also have a nice article about VirtualBox and KVM! So go out and grab a copy!
X deletes input devicesJanuary 15th, 2011
Today I restarted my notebook to boot into another kernel. Unfortunately I couldn’t log-in to the desktop because neither the mouse nor the keyboard was working. The Xorg.log gave me a hint what happened.
That all affected my GRML installation. Unfortunately you can’t change to a virtual terminal while there is no keyboard control, so to change anything you have to connect via SSH or boot from live CD or USB. The error reported in
/var/log/Xorg.0.log looks like:
So you see, all input device are turned off. Annoying!!
To avoid this problem you have to add the following section to your
That should solve the problem. If you don’t have a
xorg.conf yet you can create one with:
This will create
/root/xorg.conf.new , so you just have to copy it to
Since it was the first reboot for about 30 days and I updated/installed a lot of new software, so I’m not able to blame anyone generating this bug. But if you are feel free to do so ;-)
Alternative to vzprocpsJanuary 14th, 2011
As far as I know the OpenVZ associated vzprocps-tools are just available in version 2.0.11, at least for Debian. Unfortunately they are damn buggy in this version, so unusable…
There are two smart tools included in
vzps . These programs help you a lot dealing with processes of your running containers. But in 2.0.11 they aren’t working:
It seems that there is an update, but not available as
.deb yet. Here is an example for an alternative to
vzps to find zombies:
It’s a bit complicated, but you can write a small script to grep for further things..
YEAH - second in fM contestJanuary 9th, 2011
As I announced I took place in a programming contest organized by freiesMagazin. In the end I’m proud to tell you I’m second!
I still explained my tactics and my map parsing and all in all five other programmers joined this contest. Today the editorial staffs announced the results:
|Ranking||Programmer(s)||Score in 2500 games|
|1.||Demel and Keiblinger||232.595,79|
You see I wasn’t able to obtain half of the points of Demel and Keiblinger, looking to the results for each game there was no chance for my bot to beat them. But nevertheless I won the second rank! I couldn’t find any contact information of these guys so I wasn’t able to congratulate personally but if they read this article: Nice work guys ;-) Of course congratulations to the other programmers, even if you didn’t win, taking place is what counts!
By the way the organizer informed me about an
de.binfalse.martin.fmcontest.map.DMap.dirTo(DMap.java:192) , so that my bot quit working 17 times. But I won’t update my code since it has no sence beyond this contest… It’s just to inform you.
Last but not least my thanks goes to the freiesMagazin itself. It was a very nice contest and I’m really happy about the voucher! I still have a good idea what to buy :-P
P.S.: Since both programmers on the first rank should split their voucher of 50 €, they both won a voucher of 25 €. That means with a voucher of 30 € I won the biggest value ;-)
apt-get install WPJanuary 8th, 2011
Finally I also upgraded my blog to Wordpress@3.0.4, eliminating a critical bug.
Rumpel frequently reminded me to do that, but I was too lazy to find my own modifications to the WP core… But today I did! And thinking ahead, here I record what I’m changing to this version! Majorly for me, but maybe you like it ;-)
Display whole tag cloud in wp-admin
When you create an article WP by default only displays the 45 most-used tags in the sidebar. I want to see all of them:
File to change:
File to change:
If I want to insert a link into an article I often use the button above the textarea. It’s very friendly from WP to remind the users to start links with
http:// , but for me it’s only disgusting because I usually copy&paste the URL from the browsers address bar and have to delete the
http:// from the pop-up…
To delete them permanently edit
wp-includes/js/quicktags.js . Unfortunately this script is just one line, so a diff won’t help you, but I can give you a vim substitution command:
Update 07. July 2011: For WP > 3.2 you also need to apply this regex for
wp-includes/js/tinymce/plugins/wplink/js/wplink.js to also eliminate this disgusting
