Statically typed languages like Java and Scala allow us to exclude large classes of programming errors before the first test is run. Unfortunately, these guarantees are limited to the local behavior within a single process, the compiler cannot tell us that we are sending the wrong message to another actor. Therefore distributed computing comes at the cost of having to write large test suites, with timing-dependent non-determinism.
In this presentation we take a peek at the current state of a promising solution to this problem: parameterized ActorRefs plus static effect tracking. With these tools we can instruct the compiler to yell at us when we forget to send a message or send it at the wrong time.
The talk will be in English. After the talk, we will have beer and pizza at the meetup location.
About the location
The entrance is in the middle of the building, at the roofed area near the stairs. Someone will welcome the attendees and guide the way to the elevators. Meetup location is at seventh floor.
