   Wouldn't a blog be generally simpler and, thus, generally comparatively a better candidate for a "static" site than "a social network application"? The Hacker News pages are "static" -- correct? For my s

   The Hacker News site is (a) "static" or (b) "complex"? A case of irony?

    I believe I get fully what you are saying. At one point, we need a correction: The optimization was to schedule the fleet for FedEx. They were spending big time money on the airplane operations, and a better schedule, saving even 1% of

    So LIGO detects a gravitational wave. Optical telescope data indicates that the wave was generated 10 billion light years away from two neutron stars. So, then, LIGO today affected the two neutron stars 10 billion years ago? Affected the

    About people in math and the more technical parts of computing, I've guessed that poor socialization has played a role. But when my career was okay, it was in computing, and I did well enough in the socialization . Can consider thes

    Simpler than that: For "applied" optimization, much of a career, many applications, f'get about it. I was naive, manipulated, and fooled. Now on the OP, there is a book title with "Applied Optimization", and I&#x2

    Fine. But I'm still not finding the private planes, yachts, mansions, or even houses with wife and children of people with careers in "applied" optimization. Computing, startups, venture capital, lots of careers. "Appl

    The point of the post is that in my long experience there was not much about optimization that in any significant practical career sense was "applied", i.e., no jobs even to keep one from living on the streets, far from a career t
