Types And Typeclasses

2026-07-06T14:57:07Z

In some ways typeclasses and types are the Haskell implementation of the idea of “It’s turtles all the way down!” I post this on my blog in the sure and certain knowledge that if I’ve misunderstood something someone will quickly comment and set me straight!

I would consider myself a skeptic when it comes to vibe coding and the use of LLM’s. But credit where it’s due. Gitpod did a good job of slapping together a small, simple Elixir app.

The Essence Of Agility

2025-08-04T16:05:31Z

Doctors Don't Do Side Projects

2025-07-03T13:48:33Z

A few people when discussing side work by developers trot out the argument “No one asks a surgeon if he or she does side work!” This argument is flawed in a few major ways.

If You Laid All The . . .

2025-02-25T16:37:38Z

It’s sometimes helpful to people to have an analogy to help understand the magnitude of something. That is, to get an idea of how much money one is discussing sometimes authors will refer to a line of dollar bills laid end to end and how many times it’d circle the earth at the equator. In that spirit we’d like to give some helpful approximations of the number of various kinds of technical people there are in the world to help people get a grasp of the magnitude.
