My appreciation for openSUSE breaking random desktop functions with their "KDE Current" releases, without offering a way to go back to the previous working state, is quickly reaching level zero.

Latest victim: Display Configuration broken.

Previous victim: Google Calendar integration.

Dear lazyweb, what happened to Google calender sync in KDE 4.12? After upgrading, Kontact can't sync my Google calenders any more and the connector is gone from the list.

Now, how about you, dear Imgtec?

Quake 3 Arena mit 133 fps -- auf dem Raspberry Pi! Dem freien Grafiktreiber sei Dank. Ich kann mich noch gut erinnern, wie Quake 3 Arena damals mit der Diamond Monster 3D (3dfx Voodoo1) ruckelte wie irre, weil 2 MByte Videospeicher einfach nicht reichten... (mfi) #q3a #raspberrypi

Das wär doch was :-)

Bringing Star Trek to life: LCARS home automation with Arduino and Raspberry Pi

http://adafru.it/b100872

This LCARS home automation from YouTube user boltszmann138 a trekkies dream come true!

…I came to the conclusion that QT works fine for me. There are two programms running:

First, there is “ha_interface” on the raspberry which on the one hand connects to the arduino via usb and provides a tcp server for clients on the other hand. Clients can request sensor values by sending “request:sensortype:sensorid” over a simple QTcpSocket. If the arduino sends an interrupt (for example: reed contact 1 is now open), ha_interface sends a broadcast message like “broadcast:reed1:opened” to all connected clients. Parsing of these commands can easily be done via the QString::split(“:”) function. The biggest problem was: I dont want the clients to poll for the reed contact state, since they change very seldom. On the other hand, I didnt want to miss that event. So I had to find a way how recognize an interrupt (by emitting a signal) in the serial usb connection. This gave me the answer: http://www.webalice.it/fede.tft/seria… (part 5) and http://fedetft.wordpress.com/2010/04/… . Several connected clients can talk to each other via the interface and share for example their local “red alert on” or “system locked” bool variables.
