Lightning Talks
summary
A rapid sequence of five-minute demos names concrete wins: a citizen‑science site uses images from the Dark Energy Camera and reports 2.5 million users and 250 million classifications; a hackathon app (Hack Club Bank) adds a pending ledger to avoid bounced checks; a password rule change to 12+ chars with mixed cases and symbols stretches brute‑force time to 3000 years; multiple open‑source projects ship — MagnaChat (Rails/Stimulus + OpenAI), mruby on Arduino, an ActiveRecord summarize gem, and a foster‑placement tool that places 500 children.
