Hi, I'm Clément

I'm a functional programmer working at FretLink. I love discussing about FP, distributed systems and cloud architecture. If you've seen this page pop up in "nearby", let's have a chat!


Functional Programming is often seen as a nice tool for small-scale concerns, not as a tool for application design. However, functional programming comes with interesting tools aimed at solving these boring (or deemed boring) concerns: dependency inversion, observability).A functional solution, called a monad stack, allows to combine all this cross-cutting concerns and behaviours with no magic (or not too much). Let's see how it works and how it relates to the current "Tagless Final" trend

Config files are getting bigger and bigger. Config languages are limited (by design). Using a general purpose language for config looks like a good idea but has severe drawbacks. Dhall is designed to bring flexibility and abstraction to config, while keeping key properties.

The `traverse` function is so pervasive in functional programming that it became a joke: `traverse` is the new `42`. Since it's a bit abstract until you actually encounter it, let's dig a little and review some case where… well, it was _actually_ `traverse`.
