    Those would be OCXOs. TXCOs are just temperature compensated.

    AAL578 flew by Tom's River (Bay Shore area, where the photos were taken) around 20:43 on December 8th which is right when the photos were taking, on a heading that would result in …

    6 and 7. If you squint and lean on a bit of confirmation bias, photo 9 looks like a commercial airliner with the Alaska Airlines livery.

    The photos I've seen posted look very obviously like commercial airliners and helicopters with their navigation lights on. You can even make out the American Airlines livery on the…

    They almost certainly had flight spares but with two weeks until your launch window, there is zero chance you are deintegrating multiple systems, swapping in the spare, reintegrati…

    Absolutely! I enjoy my daily routine and all of the nuances associated with it (whether that's just the result of addiction is a different conversation). I was just suggesting that…

    It sounds like you'd be better served by caffeine pills then. No need to bother with a delivery mechanism you don't enjoy when there are easier solutions out there!

    The UC Health system serves the general public through direct services and their research and teaching functions.

    Efficient doesn't really mean anything without an thorough understanding of the local energy grid. Distributed solar mixed with wind and some gas peakers? Sure, probably better fro…

    That's very much not true about heaters. The most common systems in the US are gas, heat pumps, and oil. Resistive heat is nearly always an emergency backup in places that get mean…

    Pistachios and Almonds use 4x less acreage than Alfalfa, hay, clover, etc. These feed and grazing crops use almost exactly equal acre-feet of water per acre as pistachios and almon…

    For sure! Even Buy-and-dry schemes seem to be struggling with political backlash and those landowners are being fairly compensated in voluntary transactions. It's not going to be p…

    There is plenty of water in the south west, we just use most of it to grow animal feed in the desert. Even worst, much of that water is subsidized by the US Government which allows…

    I'm also not convinced that they're even out of Far-field. That looks like a roughly 5m dish, which at 10GHz is still in the radiating near field at 1km. I wouldn't be surprised if…

    Less that its so common, more that a small percent of people cause all of that pollution. They usually convince themselves they are being environmentally friendly because "I just u…

    The stoves just put off a lot of particulate pollution. Stoves don't completely combust the wood or do so at the wrong temperature which results in much more pollution than burning…
