I wrote about the designing the perfect type signature syntax in Ruby.

Why do we do this ourselves? We are feeding the rich with our knowledge without any benefits in return. Instead, they make content hard to read, hard to search, hard to edit, and hard to follow. And hire algorithms to throw trash into our feeds. More: dudulski.pl/2025/10/15/f...

Nine years old and still so relevant - my classic blog post on getting out of the survival mode: no-kill-switch.ghost.io/fly-you-fool... Quoting Roy Osherove: >80% of dev teams never get out of it. Let that sink in for a moment.

My heuristic for using GenAI--use it in ways that cause more thoughts to go through my head, not fewer. For example, I had Claude give me an extended tutorial on eigenvalues, a topic I had been avoiding.
