When HBO's Silicon Valley became real: Not Hotdog, the Weissman score and tabs versus spaces

14 questions · by Quizbun

HBO's Silicon Valley hired tech consultants so its jokes would hold up, and a few of those jokes escaped into the real world: a compression metric a Stanford professor invented for the show, a hotdog-detecting app you could actually install, and a fake Google that the real Google linked to. Each Question starts from a scene and asks what happened next in real life. The Explanations cover the real tech behind the jokes: transfer learning, class imbalance, and why a score built on logarithms depends on your stopwatch.
