Hi everyone,

I’m happy to introduce Crank, a library that makes modelling complex stateful logic in Elixir much more enjoyable and maintainable.

Crank draws inspiration from the long evolution of finite state machines acr

Summing up my thoughts about “slop advent.”

The accusation ‘this is slop’—applied to any body of information, be it letters, pixels, or notes—is pure, undiluted argumentum ad hominem.

I’ve posted a couple times about this topic before:

As a slowpoke, I wrote my own take on Clean Code and other dogmas of a Computer Science.

Clean Code doesn't work—not because the principles are wrong, but because the real world is dirty, chaotic,

Mold parses JSON APIs, webhooks, HTTP params and other external input into clean Elixir terms - coerces types, renames keys, checks structure, and returns {:ok, result} or {:error, errors} with traces.

I’ve been wondering for some time now if there is a way to instruct ecto to run all, not yet applied, migrations inside a single transaction.

For example, let’s say I have two migrations:

Hey Bart and all,

I’m not sure if this has been talked about before (I’ve looked but of course I could have missed it) but one of my biggest pain points with working with Hologram is that the full documentation doesn’t live in hexdocs.

I used to manage all of my Elixir stuff with ASDF but I’ve been consulting on a Ruby project and mise seemed to work better there so I made the switch. However, this seems to have broken my Elixir LSPs. I don’t know too much about what’s going on under
