Since Android 3 it is no longer possible to access the phone via USB mount. The reason being that Android puts everything into a single partition. As this single partition is always mounted by Android it is not easy to have two users (Android system and PC user) to write on this single partition. Therefore one needs a separate way to access the whole or parts of the filesystem. One solution is ssh, see ssh and rsync for Android, or MTPFS.
apt-get install mtpfs
mtpfs /mnt/sd # mount
... # use it
fusermount -u /mnt/sd # umount

When the CPU is not properly cooled down, then the PC crashes, see below video.
The solution for this particular case: Upgrade the BIOS.
Today I received a free copy of a student-version of Lexware Financial Office Pro 2015 including a license key. Lexware is a financial accounting software which is easy to use and quite well suited for small German enterprises. I installed wine 1.6.2 on Ubuntu 14.04.2 LTS, which consumed almost half a Gigabyte of hard-disk. Then I tried to install Lexware. This simply didn’t work. Searching in Google and winhq.org delivered similar results. So, in short, if you want or need to install Lexware on Linux, just forget it.
GSI Helmholtz Centre is a heavy ion research centre near Darmstadt. I visited this research facility on the 06-Jul-2015. It takes a couple of months to acquire a visiting day. Here are some impressions. I highly recommend the facility.
