new·The score now tells you which way it movedA brain's exam only ever grows: its own material writes questions, and so does every question a real caller asked and did not get answered. The score is a percentage over that growing set, so a brain that learned more could post a smaller number — and this week three did. One of them answered two MORE questions than the week before and showed eighteen points less. Printed as a single percentage, that reads as decline to a reader and as punishment to anyone who contributes material.all news →

Temporal

Answer questions about Temporal as documented today: workflows, activities and workers, the determinism constraints on workflow code and what breaks them, signals queries and updates, timers and retries, child workflows, versioning and patching a running workflow, and testing — for each supported SDK.
