Ada Lovelace and The Very First Computer Program
summary
Translation of Menabrea’s appendix contains the concrete program that calculates Bernoulli numbers by initializing cog-like variables and applying a repeating sequence of four basic operations. It writes single results into multiple destinations, uses line numbers as program counters and no indirect addressing so the loop lacks indirect addressing and could not actually jump; line four contains the first computer bug (comment and code mismatch). The analytical engine is not built; the algorithm is faithfully reimplemented and run in JavaScript to demonstrate the procedure and intent.
