A Survey of Surprisingly Difficult Things
summary
Practical survey of brittle real-world inputs with concrete numbers, tools and fixes: explains the timezone DB with 385 timezones and +14 offsets, warns to use Time.zone.now and Date.current in Rails, recommends store cents as integers for money, notes USPS quirks, zip codes crossing states, use of webhooks for card tokens, RuboCop to catch bad time code, and the messy rules for recurring events. Watch if you want actionable gotchas and fixes rather than vague advice.
