this insult to author of 'intro to OS abstractions' is worse than all vulgarities in this thread :-(

this link is the 'intro to os abstractions' book https://www.google.com/url?sa=t&rct=j&q=&esrc=s&source=web&cd=&ved=2ahUKEwjyxsD-gcv1AhWDsKQKHYgFBloQFnoECAUQAQ&url=http%3A%2F%2Fdoc.cat-v.org%2Fplan_9%2F9.intro.pdf&usg=AOvVaw3V31IcFr5AdwkH5d_JXrVu
