Well, this seems as good a time as any to post that I am seeking PhD students to join my research group in Regina, Canada.

I work on making dependently typed programming languages easier to use...

Reposted my “Outlining typechecking / Feeding the lambda calculus its own tail" type theory posts to my website, using the cohost web component tool.

Playing around with #dependenttypes and started writing a (currently pretty silly) #singletons library port for #purescript - https://forge.id1.in/aj/purescript-singletons/

#haskell #functionalprogramming

The other episode was on #DependentTypes in computer programming, intuitionism in #philmath, philosophical questions concerning #evolution, and #pseudorandom number generators.

We build on folklore around spaces and pattern matching to formalize how sheaves and Grothendieck topologies can model dependent matching

Overview: Hacker News debated the utility & necessity of dependent types in programming & theorem proving. Discussion covered pros/cons vs. alternatives, ease of use, performance, community support, and adoption challenges. #DependentTypes 1/6

Has anyone ever used #dependenttypes for anything practical? I'm struggling to find a use case that's not track the length of an array
