Welcome to the eighth – and final – week of recordings from the Dyalog User Meeting in Belfast!

Dyalog '18 Videos, Week 7
Our stated goal has been to provide variety each week, and I’m happy to say that I have not been able to find any kind of theme in this penultimate set of presentations from Dyalog’18 in Belfast.
