Name one that actually boots the Linux kernel, and doesn't just run in user space. (Yes, I am a fan of ZFS, but not the Linux implementation.)

You really should get out more. ZFS on Linux is not to be confused with the ZFS Fuse project. You can boot from a ZoL filesystem. In general ZoL is about as stable, complete, and reliable as any ZFS.

Speed of light in fibre is about two-thirds that of vacuum.

Direct-line distance from New York to Los Angeles: 3940 km
Speed of light in vacuo (= approximate speed of electromagnetic radiation in air): 300,000 km/s
Travel time: 13 ms

If speed in fiber is approximately 67%, then travel time is approximate 150%
Travel time: 20 mS
The route on the surface is very unlikely to be an exactly straight line, so figure maybe 25 ms

Half of the (round-trip) ping time is maybe 80 ms for a good fast end-to-end connection in practice. So we're talking less than 10% of that for difference between fiber and wireless, not taking into account the comparative number of repeaters in each case. Doesn't sound like this hare-brain idea would do anything significant for latency.

So, my ideological transition went from Reagan Republican to Goldwater libertarian to Rothbardian Anarchist.

Personally, I am socially boring, somewhat socially conservative, and evangelically religious. I don't (politically) care what other people do to themselves; as long as they and their government don't do it to me or my family.

I've really given up on government as an entity that can create moral good in the world; it seems that historical attempts to have government play that role have turned out poorly, both for the people involved and the morality being coerced.

I've tried to explain where my head is at so you can try and tailor the message in a way I might understand.

Can you help me understand what the "war on women" rhetoric is about?

Assume that I'm an intelligent person, with degrees in Math and CS, and extensively educated in history, medicine, politics, and economics.

Yet, despite this, I cannot for the life of me understand how people with different ideas came to those ideas via any plausible mental process. It seems to me that there are fallacies all around - why aren't they seeing them?

I want to assume that they are acting with good intentions, but I am unable to debug or understand them and their decision making process.

So, this is a legitimate request for help, and not a thinly veiled attempt to demean or attack someone.

Will you explain what the "war on women" is in a way that will cause me to want to listen? Explain what things are included in this war, and what things aren't.

I mean, my inclination is to throw a flag on the play before it even begins; a political "war on women" appears to suppose that all women should think and want the same things politically, which is self-evidently insulting to women and denies their essential individuality.

For instance, the only people I know personally who are tireless anti-abortion activists (and I know several) are all women. Are they part of the war on women?

I'll stop, and hope you craft a well-intentioned response.

NASA had nothing to do with the microwave oven. Diathermy (therapeatic heating of human tissue by radio waves) was being used in 1930. Westinghouse demonstrated cooking food using short waves in the 1933 Worlds Fair. The cavity magnetron was perfected early in WW2. Percy Spencer noticed a candy bar in his pocket melting when he was working close to an operating radar in 1945. He experimented with heating food in a metal box fed from a magnetron the same year; Raytheon filing a patent for it. Raytheon built he first "Radarange" in 1947. A public vending machine was producing hot dogs in Grand Central Terminal in 1947.

The one thing I want to point out is that you should recognize the name "Cass Sunstein"; he's not some random academic, he was part of the Obama administration, and has a bunch of ideas that you will find either kooky or great, depending on how you align politically:

He's also good about co-opting terms he disagrees with as a way to try and attack intellectual opposition. He calls a bunch of things libertarian that are flagrantly NOT libertarian, for instance.

Someone else covered this but is buried.

Bee colonies do not freeze in the winter. They starve.

We've been keeping bees in North Dakota, which is colder than wherever you are, for 7 years. All 3 of our colonies survived last winter. One is strong enough that we've split it this spring to try and prevent a swarm.

The way that bees operate in winter is amazing. The bees form a sphere, with the queen near its center. They vibrate their wings and bodies to create heat. The bees on the outside of the sphere obviously lose heat the fastest. The bees on the inside stay the warmest. The sphere of vibrating bees constantly turns itself inside out, over and over, so that the cooler outer edge bees return to the warm core and replenish their warmth, while the warm bees from the core circulate out towards the edges after they've recuperated.

This consumes lots of energy (and food).

As the cluster of bees does this, it moves upwards in the hive, consuming stored honey.

When they get to the top of the hive, they stop migrating. If they run out of honey, they die.

We use 2 deep supers and 1 medium honey super to over-winter our bees.

I share those kind of concerns in general. The AOpen MP945 was an example of using an excellently engineered cooling system. There basically was nothing else in the box besides the CPU that made any appreciable heat. Mine was very quiet and never degraded. The NUC from what I've heard has similarly great thermal engineering. But when the cooling system on anything like this degrades or fails, you're going to have to try to find and pay for the expensive custom part. You can't just slap a new commodity fan in there.

Interestingly, my AOpens have held up better than anything else I've had. An endless train of motherboards have succumbed to capacitor failure, but none of my AOpens.

Without a dBa @ distance measurement, with comparisons to other equipment using the same measuring equipment, "quite loud" is not really a useful characterization. Even then the dBa level alone doesn't tell you all you need to know about the acousic objectionability factor. My good old AOpen MP945 with GMA950 graphics (exactly the same size as the good, original Mac Mini) idles and even does useful light work in silence in a quiet residential room with nobody else in the house to make any noise, and without any radio or TV or air conditioner running. Even all out, it is plenty tame, on the good side of laptop noise. The cooling system in a dynamite design.

But my AOpen GP7A with the power hogging NVidia graphics, even sitting idle, periodically roars like a bastard as some random daemon makes a quick tiny demand. When it is really working it sounds like a freight train or jet plane taking off, and oven-like air is rushing out of it.

The NUC takes even less power than the MP945. Certainly the 5i3 is damn quiet. I expect the 5i7 isn't all that noisy. I'm pretty certain it is a damn sight quieter than that GP7A.

Logic is a pretty flower that smells bad.
