Jfokus VM Tech Summit is an open technical collaboration among language designers, compiler writers, tool builders, runtime engineers, and VM architects. We are sharing our experiences as creators of programming languages. We also welcome non-JVM developers on similar technologies to attend or speak on their runtime, VM, or language of choice. We are dividing the schedule equally between traditional presentations 45 minutes and "workshops". Workshops are informal, facilitated discussion groups among smaller, self-selected participants. They enable "deeper dives" into the subject matter. Space is limited: This summit is organized around a single classroom-style room, to support direct communication between participants.
