Debian.Developer->add_member(“mika”)

Thursday, May 28th, 2009

Since 2009-05-28 I’m an official Debian Developer. Thanks to all involved people. Special thanks to Gerfried ‘Rhonda’ Fuchs for being my advocate and a helpful package sponsor, to Alexander ‘formorer’ Wirt for being a helpful package sponsor, to Christoph ‘Myon’ Berg and Bernd ‘bzed’ Zeimetz from the frontdesk and to Marc ‘he’ Brockschmidt for being […]

Boot an ISO via Grub2

Monday, May 25th, 2009

With grub2 you can directly boot an (iso9660) ISO using its loopback option. This is great because it provides another nice rescue scenario – for example when using grml (the Debian based Linux Live-CD for sysadmins). You no longer need to extract kernel and initrd from the ISO to be able to boot it using […]

/proc/partitions und 1024 Bytes

Thursday, May 21st, 2009

Auf der Mailingliste der Linux-User-Group-Graz gab es die Frage, ob man sich darauf verlassen könne, dass die blocks-Einträge in /proc/partitions unter Linux immer eine Größe von 1024 Bytes haben, bzw. wie man das verifizieren kann. Nachdem die Mailingliste aktuell leider kein öffentliches Archiv hat, werfe ich meine Antwort zusätzlich auch hier ein: Ok, zuerst schauen […]

OSDC 2009: done

Monday, May 4th, 2009

Die letzten Wochen waren dank der Grazer Linuxtage sehr stressig. Direkt danach ging es auch noch auf die Open Source Data Center Conference nach Nürnberg. Ich kann mich Kristian Köhntopp und Michael Renner nur anschließen: super war es! Interessante Leute, Gespräche und Vorträge sowie perfekte Organisation seitens des Veranstalters. Die Folien zu meinem Vortrag ‘grml […]

Unix time: 1234567890

Sunday, February 15th, 2009

I hope you know the comics of xkcd and abstrusegoose about Unix time. Unix time? Unix time, or POSIX time, is a system for describing points in time, defined as the number of seconds elapsed since midnight Coordinated Universal Time (UTC) of January 1, 1970, not counting leap seconds. It is widely used not only […]

Tuesday, January 13th, 2009

I got a mail from Linux New Media telling me that they want me as jury member for the Linux New Media Award. The process is simple and for now they just ask me to send my nominations for the following categories: Outstanding Contribution to Open Source / Linux / Free Software Most Linux / […]

Dreambox Flashen

Tuesday, January 6th, 2009

Ein Windows-Tool zum Flashen einer Dreambox DM600PVR zu Verwenden ist klarer Stilbruch. Via TFTP wäre es vertretbar aber umständlich. Das geht viel einfacher wenn man die Dreambox übers LAN erreicht: telnet $IP_OF_DREAMBOX mount -o remount,rw /boot rm /boot/* reboot Im Browser dann auf $IP_OF_DREAMBOX gehen und über den Punkt Firmware-Upgrade das gewünschte nfi-Image hochladen und […]

Apple Tastatur unter Linux – das Problem mit den Funktionstasten

Wednesday, December 31st, 2008

Die Funktionstasten (F1, F2,…) von Apple-Tastaturen erfordern je nach Modell das Drücken der Funktionstaste (fn), um unter Linux wie gewohnt zu funktionieren – wie es der Aufdruck auf der Tastatur auch schon andeutet. Dafür gibt es einen Workaround, Powerbook-Usern wird vielleicht das Stichwort pb_fnmode (/sys/module/hid/parameters/pb_fnmode) was sagen. Das war auf dem USB-Tastatur-Modell MB110D/A und Linux-Kernel […]

mika’s advent calendar – day 24: zsh globbing

Wednesday, December 24th, 2008

The advent calendar started with a Zsh tip, let’s end the advent calendar session with a Zsh tip: globbing. Globbing is like pattern matching. When running ‘ls *.txt’ you’re using globbing. But the globbing feature inside Zsh is much more powerful. Quoting the H-Glob function (“help globbing”) of grml’s Zsh configuration: % H-Glob / directories […]

mika’s advent calendar – day 23: nagios

Tuesday, December 23rd, 2008

Nagios is a well known and established Open Source Monitoring System. It’s flexible, easy to deploy and a tool every sysadmin should know how to deal with. I guess most readers of my blog use or at least know Nagios so I’ll keep this blog entry short. But one tip for sysadmins managing Debian systems: […]

mika’s advent calendar – day 22: patterns in mutt

Monday, December 22nd, 2008

The console mail client mutt has some nice features and I noticed that even some long time users of mutt don’t use some of the most rocking features. What’s definitely worth knowing: patterns. Want to display only mails sent from foo@example.org? Select the limit command to show only messages matching a pattern (bound to ‘l’ […]

mika’s advent calendar – day 21: grml-debootstrap

Sunday, December 21st, 2008

I wrote about FAI for deploying systems a few days ago – but FAI might be too much overhead if you want to install just some few Debian systems and prefer to use a configuration system like puppet instead. Then using grml-debootstrap might be an option for you. As you might know grml is a […]
