Wow, I just discovered EEVblog which has awesome video material for electronic geeks. This one will definitely help me choosing a new multimeter + its just fun to watch – stay tuuuned!
oh yeah, I guess I finally got the basic difference between a Transistor and a MOSFET:
Transistor is current driven, a MOSFET via voltage! Thanks to Pete, and his fabulous SparkFun screencasts:

I had the problem of my Mac not going into sleep when external screen is connected and closing the lid. Luckly I came across this advice which indeed, did the trick:
1. Disable external Monitor
2. Type `sudo nvram boot-args=”iog=0×0″`
3. and restart
For the record: Here’s my favorite realworld hack I got once told by my lovley coworker Roel:
How to clean a messy whiteboard.
Remember the situation when one used the wrong pen for the whiteboard and can’t clean it? Just take another pen which can be erased and go over the non erasable parts – suddenly everything gets clean away:
Or in the words of TvLesson:
Take another dry erase marker (preferably darker than the marks that you are trying to remove) and draw on top of the messy marks. Then wipe the marks away with a dry erase eraser or soft cloth.
The new layer of dry erase marker will lift and loosen the underlying marks. It’s simple but may not work for tougher messy marks.
