You know, at the bottom of your stack someone, somewhere, needs to know a subject well enough to implement things from scratch. If what you are doing hasn&#x27;t been done before you can&#x27;t just google or find an open source library. Even if it has been done before often these things are often barely written down.<p>Do you think when Google decided to create the V8 JavaScript JIT they hired a couple of Django programmers and asked them to google &#x27;how to write a JIT&#x27;? Or do you think they specified a certain level of experience in writing JITs on the job advert?
