[ERT: 2m39s] Filepaths have been a pain in my neck for years. Paths are hard, overused, misused and mostly unsafe. In this post I present a newly released library that serves to make working with paths safer in the common use-case.
[ERT: 1m54s] Boolean blindness has been discussed over and over and over and over again. The conclusion seems to be that always using Boolean values for decisions is a generally bad idea and that using church encoded lambda calculus instead is not much better (and impractical). Here are my two cents on the matter: Use evidence instead of Boolean values.
[ERT: 4m59s] Using arguments, configurations, settings, options or instructions in any language can be a struggle. There are quite a few libraries to solve just this problem and most of them involve either some global state or an object that is carried around through the program. Seeing as neither of these options are feasible and scalable in Haskell (when implemented naively), one has to think twice about how exactly to do it. In this blogpost I propose a general scheme to deal with all of these.
