Summer collaboration with Heather Miller on Unison distributed programming library

Exciting news! Heather Miller, CMU professor and Scala Center founder, who does very cool research at the intersection of programming languages, FP, and distributed systems, will be a Visiting Researcher with us this summer. Like us, Heather is passionate about finding ways to make distributed programming more compositional. We'll be collaborating together on a library for distributed computing in Unison and some interesting demo application using that library.

People are writing Unison libraries now

I've been pretty busy reviewing pull requests to the Unison base libraries and there's already a lot of useful stuff there. Thanks to everyone who has contributed so far!

This fact got a brief mention in the Strange Loop 2019 talk, but that talk didn't make all the benefits totally clear. This article will attempt to highlight some of the more surprising benefits of Unison's approach.
