  • The way it works for power over Ethernet — and I assume USB power delivery must work the same way — is that it does not reduce bandwidth because they run the power and the signal over the same wires at the same time.

    There is a a power injector at one end and a filter at the other end that separate out the high-frequency signal and the DC (no-frequency) power into different wires.

    This is essentially the same thing as they’re already doing for multi-frequency stacking on those same wires (and on fiber) to get the crazy bandwidth in the first place. DC power is just one more low (very very low) frequency running on the same stack.





  • I spent last Spring in Nova Scotia, New Brunswick, and Quebec. Had a blast. Land’s End and the entire Gaspesie peninsula was beautiful. Watching the tides at Hopewell Rocks and walking on the seafloor while the tide was out was wild. Whale watching and eating scallops out of Digby was awesome. All manner of cool things in striking distance of Baddeck. PEI has… um… a surprisingly interesting potato museum. Go for it!

    I can press the entirely local switch and have light.

    Are you sure about that? Is it a local connected smart switch (still fancy electronics, just local) or a plain old power switch?

    If it’s a power switch, and If you turned your lights off by app over the internet, and then the internet went out, then your lights’ ability to come back on when you flick the physical switch depends on somebody having thought about this need and programmed a “oh, the switch was flicked so I better ignore the internet settings” mode.

    And if they did that, it also probably means your lights all turn on after a power outage since the light can’t tell the difference between power outage and light switch flipped off.





  • Anecdotal story: I found on a vacation with no lights and no internet but lots of physical activity it just happened by itself.

    Every night I fell into bed exhausted and slept deeply shortly after sunset. Every night in the middle of the night I woke up to go to the bathroom and wandered around for an hour or two like a Shakespeare character, then fell asleep for another shift until dawn.

    Did not notice any effects besides being well rested from getting plenty of sleep which was unusual for me at the time.






  • Engaging — very much so, at least for me personally

    Performant — mixed story. in cheap cars like my Honda Fit where the alternative is a CV transmission, manual performs way better. In sports cars where the alternative is a dual-clutch, I think the automatics have been beating the manual on the track for a few years now.

    Efficient — I think we lost that battle on all fronts since some years back
