I am spoiled — I get to work with a brilliant bunch of students and colleagues. They’ve been doing some really amazing research recently, and I’m happy to report that they’re getting some of the recognition they deserve:

I’ve blogged about all these projects before, and since most of them are in their initial stages I fully expect there will be more to report in future.  Meanwhile, it’s nice to see these folks getting recognized for their work, and it will be interesting to get some feedback at the conferences.

Congrats, folks!

It’s been about 6 years now that we’ve been working on declarative programming for distributed systems — starting with routing protocols, then network overlays, query optimizers, sensor network stacks, and more recently scalable analytics and consensus protocols.

Through that time, we’ve struggled to find a useful middle ground between the pure logic roots of classical declarative languages like Datalog, and the practical needs of real systems managing state across networks. Our compromises over the years allowed us to move forward, build real things, and learn many lessons. But they also led to some semantic confusion — as noted in papers by colleagues at Max Planck and AT&T.

Well, no more. We recently released a tech report on Dedalus, a formal logic language that can serve as a clean foundation for declarative programming going forward.  The Dedalus work is fairly theoretical, but having tackled it we’re in a strong position to define an approachable and appealing language that will let programmers get their work done in distributed environments. That’s the goal of our Bloom language.

The key insight in Dedalus is roughly this:

Time is essential; space is a detail.
