Re: [Israel.pm] My opinion on the Technion - revision 1.5

shlomi - i think you're a good example for a student that went to the 
wrong faculty.

everything you seem to find interest in, falls under programming. you 
should have gone into the CS faculty instead. you didn't know that in 
advance, i imagine (hardly anyone does) - but i think that once you 
realized this, you should have had the courage to make the switch, 
instead of forcing yourself to continue suffering. even if you have done 
that after 2 years, you could have completed a 3-years BA in CS in the 
same time you studied EE overall (it took you 5 years, right?).

i would have added this to your criticism - to put it in context ;)
