> My bigger fear is whether Netgear has one or more backdoors exploitable for use by the US government.

With Asus you can use third-party firmware (e.g., Merlin): is that possible with Netgear?


> The looting stage of collapse […]

Remember folks: pillage before you burn.


> Agreed. The market should decide if beef consumption is viable.

Until The Market™, especially in the US, starts dealing with externalities (like climate change), it should not. Something like carbon pricing (per Greenspan and Volcker):

Even Mr. Free Market himself, Milton Friedman, thought a price on pollution was a good idea:

> With one satellite, you won't get a circle on the earths surface, but a sphere.

With one satellite you get a sphere in 3D space, but if you are on a surface (like that of the Earth), that gets translated into circle.

If you are in a plane in the sky (3D space), then you get a spherical 'location fix'.


True. But the GPS receiver doesn't know whether you are on the surface or not (and at what elevation), so it must always assume 3d space, hence a sphere.

Not wrong, but I think most folks are interested in lat-long.

If you have lat-long and place it on a pre-canned map, then it's unlikely that most people will be either underground or in the air, and so whatever the surface elevation of the lat-long on the map is, that's most likely (>99% of the time?) where the person is.

At least from a UX/responsiveness perspective, this is probably a good way to do the math. (In the background get a more accurate 3D fix.)


> Is it though? All languages have the word 'nothing'.

The interpretation of the concept that been different over time. See perhaps The Nothing That Is: A Natural History of Zero by Kaplan:

I think that glass is under-appreciated. Without it we would not have telescopes and microscopes (and all the scientific (and later engineering) that came from them), and later movies and photography—the latter also led to photolithography.

Nevermind the day-to-day quality of life improvements of eye glasses. Also:

Would also need laters: modern communications would be much different if we still had to use copper cable (esp. over long distances), or microwave relays.


Agree; and pair this with the revelations and achievements in optical engineering, lest it go unmentioned.

The lack of Aristotle is surprising:

* https://en.wikipedia.org/wiki/Aristotle

Not only his systemized thinking, but his metaphysics—especially since it got later taken up by Christianity/Catholicism. I doubt we would have gotten to Naturalism (and modern science) without his influence:

* https://old.maa.org/press/periodicals/convergence/mathematic...


I agree. And modern Western science and political thought has followed Aristotle far more than Plato. In particular, the parts of Aristotle's science that got thrown out was the result of following out his empirical method further than he was able to. We have also followed his empirical approach to political philosophy rather than Plato's Republic.

Standford's "An Introduction to Satellite Navigation" course is also instructive (recorded 2014):

I like http://lea.hamradio.si/~s53mv/navsats/theory.html which has a different focus from the Ciechanowski article.

That's a 404 for me, but I think the site moved; this works: http://s53mv.s5tech.net/navsats/theory.html

Huh, weird. Both links work for me
