ShowIP: Firefox extension to show and query the current IP Address in the statusbar

Thu, 01 Jan 1970 01:00:00 +0100

ShowIP is a Mozilla Firefox extension which shows the IP Address of the current page in the browser's status bar and allows queries to different databases about it when you right click on it. The IP is colored red for an IPv4 address and green for an IPv6 address (hence the name). Since v0.7.8 these colors can be changed in the preferences menu. With a left click one can get information about the hostname of the current page. These queries are fully customizable in the settings dialog. You can also run custom local programs. The extension can be downloaded here: ShowIP 0.8.03

Ever tried the $SUBJECT task with postgresql? It's a bit difficult.

'.htmlspecialchars($c).''; } $mode = (isset($_GET['mode']))?$_GET['mode']:"whois"; $ip = (isset($_GET['ip']))?$_GET['ip']:""; $disc= '

This is an interface to the Linux/Debian/Woody whois(1) program.
For questions, etc. please mail jdittmer@ppp0.net

Please DO NOT ABUSE this interface, especially don\'t do mass lookups. The IPs are logged by the web server.

Linux kernel compile tests

Thu, 01 Jan 1970 01:00:00 +0100

Since a while I'm doing cross compile tests for all supported linux archs. Check out the results here: http://l4x.org/k/.
So far it seems that about half of the in-tree archs are at least sometimes successfully build.

Useful mldonkey scripts

Thu, 01 Jan 1970 01:00:00 +0100

To manage my mldonkey client under Linux I've written two scripts:
The first one ('donkeyrotate.sh') changes mldonkey port numbers and adjusts the iptables rules accordingly. Afterwards mldonkey is restarted.
The second one ('rss2donkey.pl') reads an rss feed and submits new links, which match a set of regular expressions, to mldonkey. Quite useful if run from cron.
There is also a helper script 'mlcmd' which executes its parameters via netcat on mldonkey console and a init script 'donkey'.
If anyone is interested in these, you can fetch them here.

namelen.sh

In a recent discussion on LKML (Link) the question came up how long an average filename is. To answer that, I wrote a small bash script. 94.15 Percent of the filenames in my home directory are shorter than 25 characters. Here is a sample output and the source code.

XFree Xinerama extension hack

Thu, 01 Jan 1970 01:00:00 +0100

When installing my 3 monitor setup I quickly discovered that the native xfree xinerama extension is incompatible with nvidia twinview. You can only have either one. This leads to applications believing I have one 2560x1024 screen and one 1280x1024 screen. If I maximized windows they would always span two screens. Therefore I spent a long time searching for a solution on google, but unfortunately there are a) few people with 3 monitors and b) no one had solved this. So I decided to patch the X server. What I've done so far is to take programs/Xserver/Xext/panoramiX.c and fake the reply like this:
