os class for placements prepration

just a surprise class for me. i was not prepared at all. just did some bc there. anyway it went fine. it was mainly unix oriented.

static (.a) vs shated (.so) library . how do i create a shared library ? find out. create a mailing list or df for placements prepration. i am not sitting for placements, but learning all these things is good. hmmm.

today i and nir are setting up dns at 36.10. good hmmm...

ok bye!!!
