[OSy] Optional tutorial for OS first assignment

[Petr Tůma]

Hello,

for those interested, we've decided to organize a brief tutorial on what 
the first assignment solution might look like (i.e. we plan to simply go 
through the steps needed to solve the first assignment and comment as we 
go). Please note your interest in the Doodle below (or just ignore this 
if you would not come to such a tutorial):

We'll close the Doodle and announce when (and if) the tutorial will take 
place on Tuesday morning.

Thank you, Petr Tuma
