   I’m 71 and can’t learn any. Typing cryptic commands? I could learn but would forget by the next day. Had the first 128k Mac. Why backslide?

   This is one of the hardest and least productive approaches to investing. Basic skills in general security analysis, knowledge in depth of a number industry sectors, and seat-of-the-pants experience that comes only with real money bets in t

   Everyone is familiar with Russian manipulation and cooperation with Donald Trump; there are arguments about its true extent, efficacy, etc. This was the Chinese version. If you know about back-end semiconductor processing, operating a TFT-L

    And while we’re on the subject, why is cell phone audio so horrible? It is worse than that delivered by the cast metal telephones with rotating dials of my youth.

    We should also note when high credibility scientists work on something for a while and then drop it altogether.

    I think it is fair to assert that if maybe one day it will solve big problems, that it should have solved a little problem already. Quantum mechanics rapidly gained credibility because once its formalism became established, it was easy to s

    You are certainly right. But what I was referring to was CA being linked to physics, but without any tangible link.

    So much money has been wasted on photonics integration. 1.5um is a huge deBroglie wavelength.

    Note that at various times, Feynman and Ed Fredkin became enchanted with cellular automata. We’ve had some significant tries apart from Wolfram.

    “I once built a face recognition system using 350 million images.” Did this make any of you a little queasy?

    You will find, I think, the gradient you allude to, to be inversely proportional to the level of physics that the reviewer has attained. Now this could have “political” implications: people with a lot invested in conventional physics might

    I’ve had more downvotes sharing my opinions about cellular automata on HN than on any other topic, so I won’t make any here. Rather, I’d like to point out that I personally have not seen a single theory, not a single piece of a theory, kno

    Curiously, the most important CURRENT application of magnetic amplifiers was not mentioned. In every excimer laser used for photolithography and thin film panel annealing, and possibly for LASIK, their is a multistage saturable inductor ch

    During stressful times, I’d have agoraphobic attacks in the car. They were pretty terrifying. I’d open all the car windows and blast the radio. But you know what worked much better? Solving math problems in my head.

    In the case of an AM radio, the electrical length is orders of magnitude LONGER than the physical length.

    Yep. Luxury goods are at least half aspirational. Until the shortages, always super buys on BMW’s with 15k in the Miami-Ft. Lauderdale area.
