Async Programming Is Just Inject Time
All I really wanted to do was learn a little bit more about different models for error handling, but then I kept seeing “effects” and “effect systems” mentioned, and after reading about Koka and Effekt I think I’ve been converted.

I enjoy writing code. Let me get that out of the way first. The problem solving, the architecture decisions, the feeling when something clicks into place. That hasn’t changed.

The boredom was palpable and the corn possibly responsible for a slight obsession with orderliness. […]
Where things stand with the Department of War
A statement from Dario Amodei Yesterday (March 4) Anthropic received a letter from the Department of War confirming that we have been designated as a supply chain risk to America’s national security.
