  3. It's also called the law of "Uphill Analysis, Downhill Invention" which states "It is much more difficult to guess the internal structure of an entity just by observing its behavior than it is to actually create the structure that leads to that behavior." Been reusing and repeating this one quite a lot, since I saw it mentioned in one of this year's RubyConf keynotes: https://blog.jessitron.com/2019/11/05/keynote-co…

  9. Similarly, if Jessitron (singling her out solely because she wrote a really good blog post today [1]) wants to talk about microservices in clojure, and folks want to keep her out because of her views on women in technology, you are ok with that also?
