Algorithms to live by and why should we care

Talkat RubyConf AU 2019 · on Friday, 2019-02-08· [developer-experience]

Covers concrete algorithms, when they actually help and what numbers matter: binary search halves the search space each guess, the 37% rule for optimal stopping, recursion with base cases, and concrete sorts from bubble to quicksort with tradeoffs in effort versus lookup cost. Shows k nearest neighbors for recommendations using distance math, sketches scheduling heuristics like shortest processing time, and ends with a real-world failure where an airline’s optimization de-prioritises a passenger, arguing for transparency and attention to who an algorithm harms.
