  • Nobody uses that, they use the spec number because that’s what they’ve been taught, and they identify with it more than the incredibly stupid ‘full/high/super/duper/ultramegahyperspeed’ convention which the idiots at the siig decided to break again in 3.2.

    Everybody literally on the planet agrees the system is moronic, you’re literally the only person who dissents, congratulations on that.



  • They’re bad because manufacturers want to pass their usb 2.0 gear as “usb 3.0 compliant”, which it technically is, and their usb 3.0 gear as “usb 3.2” because 3.2 Gen 1x1 is also 5gbps.

    Also the whole alternate mode is awesome, but cheap hub chips don’t bother trying to support it and the only people who do are the laptop ports so they can save $.40 on a separate hdmi port.

    And don’t get me started on all the USB-c chargers that only put out 1.5a because it’s just a normal 7805 on the back end.




  • Well, air-concrete-air is 2 media but 3 transitions. You can re-use the model for the transition which makes the math easier, but you still have to re-do all the math with different numbers, some of which you have to determine by analyzing the transformation the signal channel underwent through the transitions.

    I don’t think it would be an order of magnitude more power for EM trying to go through a transition between air and concrete, it’s not like the wave is actually moving the matter so much as its bouncing into it sometimes, and the change in propagation velocity and group delay coupled with frequency rolloff in the transition, but it adds a ton of noise, mostly as the group delay gives you effective multipath, and especially modern modulation relies on heavily phase measurement (PSK and QAM) which can make everything all really icky when the phase interference is that small, we designed our modulation for large phase interference like multipath reflections, etc, the assumption that going between media would cause the reflected/refracted component to heavily rolloff, which might not be the case here.




  • It’s because it’s a shade too dogwhistley.

    It doesn’t say HOW you clear out that land, maybe you ask them to leave politely, maybe you buy them flowers and take them out for a romantic weekend in Paris then cancel the return flight.

    It’s just too vague to clearly say “slowly strangle them economically while terrorizing them and bulldozing their land out from under them”.

    Hamas’s death to Israel is less subtle in comparison, although it could be construed as a disapproval of the New Zealand All Blacks especially their outside back Israel Dagg. It could even be a contempt of modern existentialist dogma through the painful reminder that, "Death to ‘is real!’
