What's to see while around San Fransico and Mountian View/Silicone Valley for a week after the Google Summer of Code Mentors Summit?

Apart from the must-see tourist attractions there should be a lot of places a hacker should visit. ;)

I thought about dropping by at +Noisebridge during their regular thursday "German corner". Feels like the most sensible time of the week to visit. Should reduce the language issue. ;)

...still finding out about the public transport networks there.
I guess I'll get a week-pass for the "San Francisco Municipal Transportation Agency (SFMTA)" as BART doesn't do the important part between SF international airport and Mountian View.
Will stay in SF itself after the summit of cause.
