In this tutorial talk, I will describe a tight and fruitful relationship between variable-length codes (bases of free submonoids of a free monoid), unambiguous finite automata and semigroups of zero-one matrices. I will concentrate on basic notions that are natural for all three worlds, in particular on completeness and rank. The latter is related to a generalisation of the Černý conjecture, which I will explain along with some other intriguing open problems.
