Dijkstra monads

Dijkstra monads in monadic computation
Bart Jacobs
CMCS 2014

This paper discusses a monad for predicate transformers (dubbed the Dijkstra monad in an earlier paper by Swamy et al. that is now also on my reading list). This post is an attempt to express a very, very small part of the ideas of the paper in Haskell, to try to make some sense of them.

F# London meetup - FSharpComposableQuery demo

F#unctional Londoners meetup - FSharpComposableQuery demo

I volunteered to give a talk/demo at the F# London meetup yesterday evening which meets at the Skills Matter Exchange.  I gave a high-level overview of what we have been doing with FSharpComposableQuery.  The slides and demo code I used are available here, and there is a video here.  I haven't watched the whole thing and am not sure how comprehensible it (or I) am; I get that weird feeling because my voice sounds different than I think it should and can't watch it very long.  YMMV.

The talk seemed to go over well, and there were 30-40 people.  It was a very friendly atmosphere and I talked afterwards with several people that are familiar with settings where what we have been doing would be useful, so I'm hoping we'll get some feedback from anyone willing to try it out.
