VirtualBox: Boot from USB
Hi,
Virtualbox allows to boot from USB. But this feature isn’t exposed to the GUI.
Lets start. First of all determine the physical disk. Open Powershell and query the disks by WMI

Raspberry Pi: eibd with a KNX USB Interface
Hi,
a reader of my post asks me if it possible to connect the eibd bus with a KNX USB Interface instead of the TPUART board. These interfaces are available by several vendors(Siemens, Gira, Merten etc.).
I have no KNX USB Interface for testing and therefore Bastian Herzog did that part and supports me to improve the script. Very special thanks to him. Together we have get this started.
As descripted in the previous post setup your Raspberry Pi with raspbian:

Linux: Switch a idle hard disk into standby mode
Hi,
I have running a debian based multimedia server. The operating systems is installed on a compact flash card (/dev/sda), the data resides on a external USB SATA harddisk (/dev/sdb).
The (Server 🙂 ) Hardware is a Fujitsu Futro A240 ThinClient, with a power consumption of only 7W. I’m using the server for about 2 hours each day, therefore I looked for a method to save power and switch the USB disk to standby mode when its idle for while.
Check first if your hard disk supports the standby mode. Ensure that the disk is idle, otherwise the disk is immediately active again.
Switch to Standby mode
root@debdev:~# hdparm -y /dev/sdb
