The ambiguity of naming
Why naming is hard, and can even be dangerous?

Very good article on the AI hype - AI is most useful in tech, there there are the highest number of, and earliest adopters
If AI was the productivity booster we should see its effects in secondary artefacts (apps released, domains registered, public github repos, video games, etc, etc)

Wrote a small library to play with rendevouz hashing, similar to HCA Healthcare's Project Waterpark from @bryan-hunter.bsky.social , and a visualization in @livebook.dev to show actor placement and replication across the cluster, based on the ID of the patient (or actor) @elixir-lang.org
