From Isaac Sukin Command-line tip: replace a word in all files in a directory:
grep -lr --exclude-dir=".git" -e "oldword" . | xargs sed -i '' -e 's/oldword/newword/g'

Der Fehler scheint nichts mit der CPU Auslastung zu tun zu haben. Um aber genauer einzugrenzen installierte ich das Tool: https://bjango.com/mac/istatmenus/. Was ich herausfand, dass es ziemlich sicher mit der GPU Temperatur zu tun hat. Sobald die GPU Die Temperatur über 100 °C geht, schaltet der Monitor, bzw, eher die Grafikkarte, ab. Neben dem Einsatz von Staubsauger und Druckluftspray installierte ich folgendes Tool: TG Pro. Mit TG Pro kann man manuell oder auch eingestellt den Ventialtor steuern. Es sieht so aus, als ob der Ventilator nur über die CPU Temperatur gesteuert wird. So habe ich in TG Pro eingestellt, dass der Ventilator startet wenn die GPU Temperatur sich erhöht. Und siehe da: Seitdem geht es wieder. Bingo!

As my iMac Retina 27” 2014 with AMD Radeon R9 M295X 4096 MB startet to suddenly switch off the screen, especially while playing a full screen game, I started to look for the cause and a solution.
Thinking it might has to do with temperature I started to research. The black out doesn’t seems to have to do with cpu %. To search further I installed https://bjango.com/mac/istatmenus/ and found out, that the screen turns off when the GPU Die temperatur climbs around 100 °C. So what to do against that? Next was to install TG Pro an App you can use to manually (or automatically) turn on the fan.
And: Bingo! As I started to start the fan and cool down the GPU Die, the iMac stopped shutting down the Screen.

I just published my first Apple TV App. It’s TV Map, an app to look at maps at the TV. As Apple since now didn’t port their Apple maps on Apple TV, I felt that something is missing. The app uses OpenStreetMap as data source and shows 4 different map types. You can navigate with buttons or use the siri remote to drag the map.

Shame on Canon not updating their Selphy printer driver for Mac Yosemite, But there is a solution. Christian Spuller created a Yosemite driver based on the mavericks driver:

Kein Druckertreiber für Canon Selphy unter Yosemite. Lösung.

Found out what the problem was as my Apple TV only showed a black screen when trying to mirror the screen: When transferring from my old iMac AirParrot was transferred too, this App causing the problem.
Solution: Remove driver as described here: http://help.airsquirrels.com/support/articles/1000106969-i-need-to-remove-airparrot-
