Nadav,
As I promised, I shamelessly copied and edited this text. For lack of a
better tool, I placed it on our Wiki. But of course, I did not tell anyone
about it, so feel free to scream and it will be promptly erased, or handled
differently.
Please see:
http://ssdl-wiki.cs.technion.ac.il/wiki/index.php/The_case_for_Linux_for_Computer_Science_Students
Shahar: I know you are reading this. Please grant Nadav Wiki access if he
does not kick you too hard.
HAIFUX: Please do not tell anyone about this page... Not until Nadav
approves it, or whenever.
Nadav: take another warning that I am going to mail some of this text to all
users of the lab - or at least to the group that complained.
Cheers,
Yossi
