Here is a useful little command to get a quick overview over nearby hotspots: iw dev wlan0 scan | grep ‘SSID\|signal\|primary channel’ SSID: 5g_station * primary channel: 36 signal: -42.00 dBm SSID: 2g_station * primary channel: 6 signal: -72.00 dBm iw dev wlan0 scan | grep ‘SSID\|signal\|primary channel’ SSID: 5g_station * primary channel: 36 signal: …
Ah yes – finally – blog post time again :) Since I am currently writing a lot of latex with vim I thought I backup share my ~/.gvimrc on my blog: 1 2 3 4 5 6 7 8 9 :setlocal spell spelllang=en_us " enable spell checking (Ctrl x + s for suggestions) :set wrap …
I started to roll out puppet to manage our servers at work and have to say I am impressed. It really changed the way I think about managing systems and is so much cleaner and easier to understand than the ‘traditional’ way. Just being able to automate often repeated steps like enabling LDAP access or …
For a long time I searched for a way to connect two monitors to an NVIDIA graphic card without using the proprietary nvidia driver (mainly because I wanted to try use OpenBSD and 64bit FreeBSD). Somehow I never read nv’s (the free Xorg driver) man page – until today. And there it is, clear as …
I just stumbled on a very good article by Ken Thompson on computer security: Reflections on Trusting Trust In this article Ken shows how easy it is to alter a compiler to compromise all binaries created with it. Although 24 years old this article is a very interesting read.

Today I configured k3b on FreeBSD. The building from ports works fine (although it took almost all morning. But then again k3b depends on most of KDE ;-)). Turns out all I had to do was to enable the ATAPI/CAM Driver: link
I just started to try out FreeBSD 7.0 (I am very impressed so far) and ran into huge problems installing my favorite window manager ion3 . Apparently the main developer had some trouble with various distribution maintainers and forbade then to ship ion (link). After some try and error (and a pointer in the right …
