Thunderbird Datumsformat ändern

Ich nutze gerne das JJJJ-MM-TT Format für Daten.

Fix missing API-help in Qt Creator

On Windows the installer installs and registers the Qt API documentation automatically.
On Linux you can install the docs separately and than need to register it manually.

Qt5:
Install qtbase5-doc
Tools -> Options -> Help -> Documentation -> Add…
Add path “/usr/share/qt5/doc/qtwidgets.qch” and if needed the other qch-files from that directory.

Qt4:
Install qt4-docTools -> Options -> Help -> Documentation -> Add…
Add path “/usr/share/qt4/doc/qch/qt.qch” and if needed the other qch-files from that directory.

SSH without password

Auf dem client ssh-keygen -t rsa -b 4096
Dies erzeugt “~/id_dsa” und “~/id_dsa.pub”.\\
Die “~/id_dsa.pub” wird auf dem server and “~/.ssh/authorized_keys” angehängt.
Die Standardlänge beträgt 2048 Bits und es heißt dies wäre ausreichend sicher.
Ich denke 4096 schadet auch nicht.

Skype video on amd64

I had some problems to get Skype video working on my Debian amd64 system.
The problems are grounded in the outdated Skype-Linux-Beta.
They offer some amd64 packages but those are contain i386 libs.
Skype-video still uses Video4Linux1 although Video4Linux2 is available since the 2.5.* kernels!
To get things working you need to use the 32bit v4l1 compatibility library:

sudo apt-get install lib32v4l-0
LD_PRELOAD=/usr/lib32/libv4l/v4l1compat.so skype
