commit-sounds – make committing more fun

Friday, December 2nd, 2011

December, release time. I’m currently involved in the release management of three major projects and it’s not always about fun. So lets make it more fun:

FAI: switch from Subversion to Git

Saturday, November 5th, 2011

Revision one in the Subversion repository of the FAI project dates back to the 27th of June 2000. Over the last few months we were discussing the switch to Git. At the last FAI meeting we decided to finally switch to Git and I volunteered to drive the migration. Today I officially did the migration. […]

Rocking Zsh: directory specific shell profiles – Screencast

Saturday, October 8th, 2011

The “Directory specific shell configuration with Zsh” is a rocking feature I use in all my projects when working on the command line. I just created a screencast where I’m showing this feature in action, including its configuration: This embedded video doesn’t work for you? Try heading over to YouTube. Since its my first screencast […]

Open Source Projects using Jenkins

Saturday, August 27th, 2011

For a (german) talk I’ll be giving soon I was interested in a list of open source projects which use Jenkins. Jenkins is a great open source continuous integration server. I was wondering whether such a list exists but since it doesn’t exist yet I created my own and Kohsuke Kawaguchi (creator of Hudson/Jenkins) suggested […]

Saturday, August 27th, 2011

Die Open Source Experts Group Steiermark veranstaltet am 1. September 2011 das Event “20 Jahre Linux” in Graz. Gemeinsam mit Alfred Bach, Jan Kleinert und Klaus Knopper bin ich als Vortragender anzutreffen. Ich würde mich über ein paar bekannte Gesichter im Publikum freuen.

Use of VCS in Debian packages – some stats

Friday, August 19th, 2011

Everyone loves stats, ok well – at least I do. I was doing some research with regards to package maintenance within the Debian distribution and since the results might be interesting for someone else – there we are. On 19th of August 2011 there have been: 16935 unique source packages in Debian/sid 9977 packages with […]

Review: Das Git-Buch

Sunday, August 14th, 2011

Ich habe soeben “Das Git-Buch – Verteilte Versionsverwaltung für Code und Dokumente” von Valentin Haenel und Julius Plenz gelesen. Das deutschsprachige Buch füllt 328 Seiten und konkurriert mit freien Büchern wie dem Git Community Book, Pro Git und Git In the Trenches. Das Inhaltsverzeichnis des Buches sieht wie folgt aus: Einführung und erste Schritte Grundlagen […]

The Zsh Pony

Friday, July 29th, 2011

I was giving a skills exchange session about Zsh at DebConf 11. I wasn’t expected to prepare the session, but since there was no video projector available in the meeting room I started to work on some notes. Looks like I suffer from presentation driven development, so the notes turned out to become bigger than […]

Creating 32bit Debian packages in 64bit environments

Tuesday, July 12th, 2011

i386 systems are dying off and therefore building 32bit Debian packages in 64bit environments is important if you still need packages for i386. For some recent projects I had to set up 64bit-only environments with the need to provide 32bit packages for i386 as well as according i386 Linux kernel packages. 1) Common Debian packages […]

Create virtual disk images using grml-debootstrap

Tuesday, May 31st, 2011

Background: Lars Wirzenius was searching for a tool to create virtual disk images. Turned out I needed something similar to improve the automatic deployment process of a customer’s platform installation. Being the author of the mentioned grml-debootstrap tool I started to work on deploying virtual disk images using grml-debootstrap. As a result I just uploaded […]

Grml 2011.05 – Codename Just Mari

Monday, May 30th, 2011

I’m proud to be able to announce a new stable release of Grml, the Debian based Live system for system administrators. This release is a very special one for me. On the one hand of course because of the special release name “Just Mari”, being dedicated to my lovely wife. But it’s also special because […]


Sunday, May 29th, 2011

4489 days later we did it, on 21st of May Marianne and I got married. Turned out it became a pretty geeky marriage, as Grml 2011.05-rc1 with codename “Just Mari” was released during the ceremony (thanks guys!), I had to solve a nice groom quiz and our event had its own hashtag on twitter. Thanks […]

I am going to DebConf11

Thursday, May 5th, 2011

Grml User Survey 2011 – the results

Thursday, March 17th, 2011

The results of the Grml User Survey 2011 are available. I strongly recommend any open source project to run such a survey. Besides gathering really interesting feedback it’s motivating for developers to read what people think about your product. Interesting facts for Planet Debian readers: With a leading 86% our users are Debian users. Further […]

Booting ISO images from within GRUB2

Friday, January 7th, 2011

You might be aware of GRUB’s loopback option for booting an ISO, I wrote about it in Boot an ISO via Grub2 more than a year ago. A few months ago Goswin von Brederlow came up with this idea: grml functions great as rescue system. So it would be nice to have a boot entry […]

Simple DNS in chroots

Friday, January 7th, 2011

Update: Ulrich ‘mru’ Dangel suggested pdnsd as nice alternative to dnsmasq and Cyril ‘KiBi’ Brulebois pointed out, that it’s not necessary to invoke dnsmasq after fresh installation as it’s running by default then – I adjusted the text accordingly, thanks for the pointers! If /etc/resolv.conf doesn’t provide any nameserver entries glibc[1] will automatically initialize the […]
