Fuzzy Name Matching in Postgres. Paul Ramsey describes how to implement fuzzy name matching in PostgreSQL using the fuzzystrmatch extension and its levenshtein() and soundex() functions, plus functional indexes to query against indexed soundex first and then apply slower Levenshtein. The same tricks should also work against SQLite using the datasette-jellyfish plugin. # 9:16 pm

Blazing fast CI with pytest-split and GitHub Actions (via) pytest-split is a neat looking variant on the pattern of splitting up a test suite to run different parts of it in parallel on different machines. It involves maintaining a periodically updated JSON file in the repo recording the average runtime of different tests, to enable them to be more fairly divided among test runners. Includes a recipe for running as a matrix in GitHub Actions. # 7:06 pm
