Will Wilson of FoundationDB explains how the team tested their distributed database using deterministic simulation. By running the whole system in a simulator with injected faults and reproducible seeds, they could find rare concurrency and network bugs.

Gary Bernhardt's RubyConf 2012 talk on testing in isolation without mocking everything. It goes through behavior versus data, mutation versus immutability, and how a functional core with an imperative shell yields natural isolation and parallelism.

Michael Hendricks of PriceCharting shares tricks and pain points from running Prolog in production for 18 months at Strange Loop. It argues Prolog is a productive modern language beyond logic puzzles, and includes a demo of changing code mid-execution.

Deviant Ollam, head of a physical penetration testing team, presents tactics for getting into buildings, from bypassing door levers with a wire to defeating bank doors. He argues that physical security is often surprisingly weak.

Technology Connections gives first impressions of using an Onyx Boox Max2 e-ink tablet for productivity, including using it as an external display. He shows what the device can and cannot do.

A three-minute clip of Steve Jobs arguing that great products come from people who care about content rather than process. He says process-focused people take over and cause decline, citing IBM as an example.

Veritasium tells how Kodak film was fogged by radioactive fallout from the first atomic tests, letting the company detect nuclear testing before anyone announced it. The video also covers the deal to keep it quiet and how fallout contaminated packaging.
