1206

Articles & Threads E2 · source reviewed

A build-first checklist for new Jev API users, linking ten open-source examples across StarCraft control, page decluttering, Wikipedia pathfinding, row-wise PostgreSQL judgment, agent completion gates, PR risk routing, safety guards, prose linting, confidence calibration, and Discord moderation.

JEV · Decision point

Organizes ten existing repositories by concrete decision pattern, helping readers move from having an API key to choosing a reusable engineering blueprint.

Provides a compact curated entry point to ten repositories already indexed by the project radar, spanning game control, data judgment, agent gates, and content moderation.

Ask HN: What do you think of Noul, a new decision primitive?

Hacker News

1213

Articles & Threads E1 · source linked

Discusses whether Noul — a probability-of-true answer — should be treated as a general software primitive rather than a Jev-specific type.

JEV · Decision point

Explores the interface boundary between probability-of-true outputs, threshold policy and conventional booleans.

Places the Noul concept in a broader software-design context.

Build your own Jev (100% local)

Avi Chawla (@_avichawla)

Articles & Threads E2 · article reviewed

A local fixed-choice scoring tutorial using SGLang and an open LLM, from next-token logits to label probabilities and application policy. It is not a release of Jev weights or training.

JEV · Decision point

SGLang /v1/score returns scores in label_token_ids order; apply_softmax normalizes them. Validate label token boundaries and prompt formatting before use.

Useful after learning Choice: distinguish local scoring, structured generation and application policy.
