The new web­site for our robotic soc­cer team is now online. The main site is based on Joomla (1.5.0-rc3 so far; yes, you won’t believe it, we’re really using a release can­did­ate of Joomla for a pro­duct­ive site!); the blog is still based on Word­Press and will stick with it.

There are still enough lay­out issues and a miss­ing login form. The new web­site now provides a more verb­ose inform­a­tion on our team and robotic soc­cer, though. Due to the lack of a loc­al­izataion plu­gin for Joomla 1.5, the main con­tent is cur­rently only avail­able in Ger­man. The blog is only avail­able in English.

Due to some miss­ing parts of System.Net.NetworkInformation, I’ve writ­ten a (very basic and libc-based) wrap­per to col­lect net­work inter­face address inform­a­tion from the sys­tem. It calls getifaddrs, walks through the ifaddrs struc­ture and cre­ates a man­aged counterpart.

NetworkInterfaceAddress.cs

Even though it may be imple­men­ted way too com­plic­ated or con­fus­ing, it might be use­ful for someone out there.

Update 2009-01-01: Well… first, the down­load didn’t work any­more. Second, there was a bug in the code :) Both short­com­ings are fixed now :)

I worry that I’m illegal as of last night:

As net­work stack changes were intro­duces in linux ker­nel 2.6.21/2.6.22, the vmware mod­ules cur­ren­lty refuse to com­pile. Based on some forum dis­cus­sions, I’ve cre­ates a small patch so that the mod­ules com­pile again.

You can down­load the patch or the vmnet.tar archive here:
vmware-workstation-6.0_linux-kernel-2.6.22.patch
vmnet.tar

Simply apply it to the con­tents of vmnet.tar and recon­fig­ure your vmware. I’ve tested it on an AMD64 plat­form, but not on a IA32 yet!

Update: Fixed a bug in the patch and added a link to vmnet.tar.

After upgrad­ing to Ubuntu Feisty, pam-based pass­word authen­tic­a­tion for Apache (2.2) didn’t work any­more. In the logs I found only some very use­less entries like

[Wed Apr 25 20:36:20 2007] [error] Internal error: pcfg_openfile()
    called with NULL filename
[Wed Apr 25 20:36:20 2007] [error] [client xxx.xxx.xxx.xxx] (9)
    Bad file descriptor: Could not open password file: (null)

After search­ing the web for a while I finally found a solu­tion which works per­fectly for me: Just dis­able all the other authen­tic­a­tion mod­ules using the fol­low­ing directive:
