Those would be OCXOs. TXCOs are just temperature compensated.

Funny timing that they are announcing their first product days after Matt Levine highlighted their lack of a public product or direction in the Money Stuff newsletter.

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 an observing on the ground looking at the port side of the aircraft, just as seen in the picture.

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.

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, reintegrating, and re running your acceptance test campaigns. And that is assuming that they damaged a subsystem. Back powering the entire spacecraft could have wrecked your power system and anything connected to it. You'd have to disposition every part of the system that was touched. It's much more involved than just swapping in the spare and sending it.

Marc Reisner's book Cadillac Desert talked about this as far back as 1986.

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 the parent comment doesn't need to use coffee for their caffeine fix if they don't enjoy it.

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 from a GhG perspective to use restive heat, even if it isn't cheaper cost wise. Running your house on a coal heavy grid with long transmission lines? Yeah, gas is probably better in the short to medium term unless you can get a good deal on solar panels and storage.

All of that's kinda moot though since modern heat pumps are insanely effective, relatively cheap to install, and work down to sub-zero Fahrenheit temperatures using only air-source exchangers.

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 meaningfully cold for any amount of time.

"sure, my house's foundation is made of cardboard, but have you considered that the empire state building could also be destroyed in a large enough earthquake?"
