"Welcome to the Advent(2), the Advent calendar of the Operating System Group at the Hamburg University of Technology. Every day of December, we will open a door and find a system call, a concept or an interface of Linux. Behind each door, there is a short article and a small exercise, for which the solution is provided the following day."
Exam on the 25th! :)
And I won't tell you whether the material is required to pass the exam or not!
Some of my students had to idea to implement the solutions in Rust, but this will require a bit more of an effort...
