For sixteen years I talked to the machine. Now I talk to people.

Four real problems, explained by someone who has been on both sides of them.

• The blank checkout page

  Silent failure in e-commerce

• COMP-3: a number that isn't

  Silent failure in COBOL

• A list that hides its own length

  Silent failure in a REST API

• LEFT JOIN: disappearing rows

  Intention and instruction in SQL
