16. Needle: The benchmark your search engine can't memorize (keenable.ai)

Machines are now the majority of consumers of web content. AI agents will soon be the largest consumers of search. Agents need search because the information required to complete real tasks is often too fresh (”Who won the Dodgers game yesterday”) or too niche (”Can the same GM sensor be used across both 2007 and 2008 Silverado and Sierra platforms?”) to live in model weights or context. But search is not built for agents: every engine, including Keenable, falls short of what

AI agents increasingly rely on search engines to access real-time and niche information, yet current search technologies are not designed to meet their needs. This article highlights the limitations of existing search engines and the implications for AI-driven content consumption.

27. BRIN is 1/4570th the size of a B-tree, until 5% of rows are updated (deepsql.ai)

I co-owned the Zonemaps module at Oracle, and BRIN is the same design in Postgres. It stops pruning long before pg_stats.correlation admits anything is wrong — at correlation 0.921, a 28x collapse. Measured on 10M rows, harness inline.

BRIN’s efficiency in managing data size is highlighted, showing it can significantly reduce the footprint compared to B-trees until a certain update threshold is reached. With insights from an Oracle expert, the article examines the performance implications of using BRIN with large datasets.
