Some time ago, Fedora 17 got a Kernel update to 3.5.3-1. Since then, PXE booting virtual machines does not work anymore. It seems that it has not been fixed in the upstream Kernel, but only the 3.5 series of Kernels is affected. A bug has been filed, but no fix is available.

After digging deeper I figured out that someone wrote a driver and published it on github. Later on, I ….Read More
How to transfer files to the Google Nexus 7

The first try was to yum -y install libmtp.x86_64 libmtp-examples.x86_64 and mount the device with fuse: mtpfs /mnt. However, it seems it is not mature enough yet to use it. If you just want to put some sound files on to your device, Amarok works pretty fine. But ….Read More

Retrospection to FOSDEM 2012 Brussels, Belgium
