Practice SQL on messy real-world analyst cases
What it does
caseSQL is SQL practice for analyst work, not toy syntax drills. Pick an industry path, query realistic Postgres datasets with NULLs, duplicates, refunds, and stakeholder ambiguity, then get graduated feedback from a 5-tier validator.

Hey HN, Henry here from Cactus. We open-sourced Needle, a 26M parameter function-calling (tool use) model. It runs at 6000 tok/s prefill and 1200 tok/s decode on consumer devices. We were always frustrated by the little effort made towards building agentic models that run on budget phones, so we conducted investigations that led to an observation: agentic experiences are built upon tool calling, and massive models are overkill for it. Tool calling is fundamentally retrieval-and-assembly (match query to tool name, extract argument values, emit JSON), not reasoning. Cross-attention…
