I finally decided to move my gallery to a (more specialised) service provider. Maybe you already noticed the new naming scheme. Even though Menalto Gallery is a great piece of software, I wanted to have an easy-to-use, safe solution that does not require manual software updates or upgrades to be installed. I’m getting lazy, I know :)

So, the new gallery is still reachable via http://phbaer.net/gallery/ but it will be redirected to http://photos.phbaer.net/. Unfortunately, SmugMug offers no secured connections to the user galleries. You will further need to enable JavaScript, just in case you deactivated it.

Please do not be alarmed by the new domain name of missing capabilities of the new service. I hope you still enjoy browsing through my collection and do not hesitate to comment or rate the pictures! :)

Yesterday, I unintentionally deleted the (master) ext4 superblock of one of my (virtual) server’s partitions by accidentally executing

pvcreate <device>

Only some seconds later, I realised that I definitively chose the wrong lvm volume. Some more minutes later, I found out that this can be (partly) reverted by letting e2fsck recreate the master superblock by first going through the information stored in one of the backup superblocks. Their locations can be calculated by mke2fs, given the parametrisation is still known. Given, as in most cases no custom values were used, the list of backup superblocks is revealed by running

mke2fs -n <device>

The -n argument makes e2fsck carry out a dry run only. Finally, the master superblock is restored by issuing

e2fsck -p <backup superblock offset> <device>

Some error messages will be displayed and some corrections will be carried out. In the end, however, I got back a fully functional filesystem with all the data … at least it seems so :)

Even though it’s quite straightforward to realise, I’ve uploaded an algorithm2e module for LyX (> 1.6.0) that adds support for the algorithm2e class (instead of algorithm).

Maybe it’s useful for some of you out there.

Back in 2005, we decided to use Subversion scm for the source code management in the Carpe Noctem project. This decision survived the last four years but based on what we experienced during this time – we even managed to somehow blown up our repositories –, the team decided to switch over to git after the World Championships 2009. We’ll have to see how things work out now and if people manage to come to grips with the new system.

Today, I tried to merge some changes for the new Spica version. As I maintained a separate repository for this purpose, I wasn’t sure about how well git merges these data. Surprisingly, it went just smooth. Only about eight simply conflicts needed to be solved. This resulted in my first lightly more complex git tree. Looks interesting in gitk :)

I just read an article on heise.de that summarises the results of the 13th RoboCup World Championships. With a big surprise I discovered that Gerhard and his team the b-it-bots won the RoboCup @home tournament and became world champion! A really great achievement, my congratulations — no, congratulations from the whole team!

Just like the b-it-bots, the 1. RFC Stuttgart managed to win both, the RoboCup German Open and the World Championships 2009. It was a great match against Tech United! Our congratulations to this great success!
