Das Update auf Mac OS X Mountain Lion ist gelaufen: unkompliziert und problemfrei. So soll das sein…

When trying to access a port and Google Chrome gives you
Error 312 (net::ERR_UNSAFE_PORT): Unknown error
there are two ways to fix that problem:

1. Rebuild from chromium sources (yuck!)
2. start chrome with a parameter

For the second solution in Windows you will need to change the Start Menu entry to e.g. „C:\Documents and Settings\User\Local Settings\Application Data\Google\Chrome\Application\chrome.exe –explicitly-allowed-ports=nnnn“ where nnnn is the port that has been blocked.
On the Mac you can either start chrome with the terminal with “
open /Applications/Google\ Chrome.app –args –explicitly-allowed-ports=PORTNUMBER“ or create you own app with Automator

By default Chrome blocks the following ports:

Bei iTunes lassen sich verschachtelte Wiedergabelisten erstellen indem man zusätzlich die „ALT“-Taste drückt. Dann wechselt das Bild vom „+“

zum „…“

Durch Klicken auf „…“ wird dann eine Unterliste erstellt. Mit dieser lassen sich komplexere Synchronisationaufgaben für iPod & Co. lösen.

This thing is really fast. CubeStormer II solves the Rubik’s Cube puzzle faster than the human world record. Four LEGO® Mindstorms NXT sets and a Samsung Galaxy S II on Android do the work.
