Create your own QR codes with the Google Charts API


Quick Response Codes a.k.a. QR Codes are appearing everywhere. How do they work? Simply point your smartphone camera with a QR app running to the logo and you will automatically be shown the encoded text or forwarded to a website. With the above QR code you will be redirected to this homepage. If you want to make your own QR code this can be easily done with the Google Charts API. Simply point your browser to https://chart.googleapis.com/chart?chs=150×150&cht=qr&chl=SOME+TEXT+OF+YOUR+OWN&choe=UTF-8 and replace the text with whatever you want. For the QR above I used https://chart.googleapis.com/chart?chs=150×150&cht=qr&chl=http://www.cubewot.de&choe=UTF-8. For spaces use the plus sign. That’s it.

Druckerwarteschlange unter Mac OS X leeren

Wenn unter Mac OS X sich die Druckerwarteschlange nicht leeren lässt hilft folgendes Kommando weiter:

  1. Terminal aufrufen
  2. Eingabe von: cancel -a
  3. Fertig!

Falls es immer noch nicht klappt kann mit „sudo cancel -a“ und anschließend dem Administratorpasswort der Befehl mit erweiterten Rechten wiederholt werden.

Facebook does not get it

There is a subtle difference between „a public“ and „the public“. A public is all of the people on the net that I know and want to share info with, the public is everybody else. Marc Zuckerberg from facebook simply does not get that difference. Wired magazine recently published Facebook’s Gone Rogue. I agree. Facebook zucks.
In a social network I want to be able to choose what and with whom I share infos, Facebook wants to share everything I own with everybody and they want to help me doing that. No thanks. Facebook account deleted.
