BAHA · Interactive Essays on the Machinery of Software

Field notes

The archive uses interactive diagrams as part of the explanation rather than as decoration: readers can drag query windows, inspect HNSW insertion and traversal, edit ingest patterns, and compare ranking or storage behavior. Its coverage is unusually systematic, spanning inverted indexes, distributed search, metrics, vector databases, and lifecycle storage. Several essays foreground measurable constraints, including a claimed reduction from 25 to 3.75 bytes per data point and experiments over ten million documents.
