Convert ogv to mkv for WDTV

In order to view videos on the WDTV, it's sometimes necessary to convert the format first.

Get an ffmpeg version that supports x264: HowTo.

Then run something like this:
for i in *.ogv; do ffmpeg -i $i -y -vcodec libx264 -profile baseline -preset slow -crf 20 -threads 0 -acodec libfaac `basename $i .ogv`.mkv; done

Xfce4 (Xubuntu) and color profiles

Similar to gnome-color-manager for Gnome, for Xfce one can use something almost as simple to load a custom ICC color profile: xcalib. Just place an appropriate entry in the "Session and Startup" preferences and everything's fine.

Connection problems with Intel Centrino Advanced-N 6230 and Linksys WRT54G router

Using my new Dell XPS 15 (LX502) with an Intel Centrino Advanced-N 6230 wireless card I couldn't connect to my WRT54G router running the Tomato firmware anymore. Neither WPA nor WPA2 worked, not even WEP. Turns out that I had "Afterburner" mode enabled, which seems to cause problems, as also described here. After disabling this feature in the Tomato interface, everything worked nicely again.
