  1. USB started so nicely. It was simple, and then they just made a sloppy mess of it, for no good reason. I have to do research on which is the optimal cable for what I'm using it for, every time I buy a new cable. They're seemingly getting a little better with 4.0 but still messing it up.

  2. I think I typically must be buying older (cheaper) devices but I appreciate that nearly all of them get charged with a USB micro B port. The fin type attachers are a real pain as they age though.

  3. Yes, the USB situation is horrible. The Micro and the C look too much alike at a glance.
    Your intro music reminds me of an English TV series, something like "The Secret Life of Machines." Yes, that's it.

  4. have You heard about this, better than floating-point calculations:
    PLSE Seminar Series: John Gustafson, "Next Generation Arithmetic for HPC and AI: An Update"


    UW PLSE Paul G. Allen School of Computer Science and Engineering
    posits and valids (interval numbers), they can/will completely replace floating-point numbers!

  5. Is there any way to test a USB cable determine functionality and data transfer speeds? (I have about a hundred USB cables I have collected over the past 15 years or so.)

  6. Thank you very much for the clarification… It does remain quite the jumble nonetheless. I've just downloaded CristalDiskMark giving the USB ports and its devices a go. I'm on an old MSi all-in-one from 2012, Windows 7. Specs of this machine only say 3.0 and 2.0 ports. Physically they are all type A with 2 blue coded ones, and the rest white. Yet, the WD external hard drive (not an SSD) connected to the USB A with white code is reported as being faster than a flash drive in one of the blue coded USB A… LOL. Yet, the blue coded ports are labeled 3.0… You'd indeed expect the blue ones to perform faster, but clearly not… chuckle.
    Personally, I've given up on all the USB promises… You just can't tell from the looks.

  7. This is the clearest, most concise discussion about USB I have found. Well done. USB, despite being confusing, delivered us from a slew of much worse connectors and standards. Soon, hopefully, the need for a drawer of misc. barrel style power cords will be a thing of the past.
