Episode notes
Effects Package More Than Return Values
- An effect packages return value plus contextual info so operations compose safely and flexibly.
- Bruce Eckel says this extra information lets runtimes manage retries, fallbacks, and concurrency automatically.
Book Turned Into A Podcast On The Road
- James Ward fed a book into an LL model and it produced a short podcast summary while they drove to a conference.
- Eckel found the machine's summary surprisingly mind-blowing and suggested new analogies like bento boxes for monads.
Describe Intent, Let Runtime Decide
- Describing what you want instead of how lets runtimes decide execution timing and parallelism.
- Eckel argues effect systems let you slide in retries, fallbacks, and concurrency without boilerplate.
