Some usefull stuff :
- MPlayer, because Quicktime doesn’t understand all fomats ! (be sure to get the recent version from mplayerhq and not the old one from Sourceforge.)
- VLC, because Quicktime doesn’t understand all fomats and competition is good.
- 7zip best compression.
I found a nice article : MacDevCenter
I picked up MkConsole and Aquamacs (Emacs) Not sure if I will catch up with Emacs … I am hesitating for about 10 years …
There are some good tips about keyboard use too.
