Test results (2026)

All students have to:

• pass two tests:
  • one on the topics tagged with [shell]; this test will take place after the corresponding classes
  • another on the topics tagged with [programming]; this test will take place on the last lab classes
• complete an assignment – write a concurrent code.

The tests will be written on the lab computers, on a dedicated virtual machine. You may (and to answer some of the questions, you must) use the terminal. You are free to use any software available on the machines (e.g., the man command). You must not use the Internet or bring any materials to the test. You may make yourself familiar with the test framework at this example test.
