Journal: My Public Key data

Journal by VernonNemitz

This post relates to the preceding "Web of Trust" post. I'm putting my Public Key on the Internet in multiple places, where people can access it and see that it is the same data in those different places --and where, presumably, only I had the ability to post that data in all those places. At this writing the data can be compared at this site and this site, and

Journal: Web of Trust

Journal by VernonNemitz

Think about the number of different sites you typically visit, and the number of sites where you joined to become someone who could post some sort of content. You've probably used different passwords at those sites, which means that, in general, you are the only person who is able to access your accounts at all those sites. Now suppose you fired up a "Pretty Good Privacy" program like "GnuPG", and created a Private Key (that you keep secret) and a Public

Sounds like the start of making each phone module into a nano-computer. Each nano-computer controls only its own module, running a nano-OS. The nano-OS would only need two things: a way to plug in a driver for the particular hardware of the module, and a communications program so all the modules can be coordinated. One particular module would have, as its "driver", the coordination program, producing the overall result with which the end-user interacts.

I tend to agree that other social animals also mostly are not quite so egalitarian. However, the way it is expressed is more about "alpha male" dominance, among animals, while among humans it is more about "social power". On the other hand, we can easily form groups to resist some current Authority figure. When our species emigrated from Africa, for thousands of years human tribes split and went separate ways because of social divisions. After the accessible world was filled with hunter-gatherers, then came more serious inter-tribal competition for resources, and the first battles. Meanwhile, something Robert Heinlein wrote appears to have been valid the entire time [paraphrased here]: "Any government can work if power and responsibility are matched." So the masses of low-status citizens can basically say, "Sure, you can have the social power, but you had better use it to deal with these responsibilities...." That is the advantage seen by those masses of low-status citizens, for themselves: less responsibilities.

One of the simplest ways to lock down a computer is to physically lock it away from access. Originally car-makers did that --you needed physical access to the computer (usually inside locked hood compartment) to do anything to it. Now they have connected it to radio waves. That is the main security hole. Go back to a solid wired-only connection, with the connection point(s) behind locked doors, and a significant chunk of the security problems goes away.

One problem is that the politics has overlooked two important things. First, those power companies build "base load" capacity plus "peak power" capacity. Often the peak-power capacity involves a different and more-expensive source of energy than the base-load capacity. Meanwhile, peak-power capacity is most often needed in the middle of the day (like for running lots of air conditioners). Well, solar power is pretty much ideal for matching the peak-power needs. There could be a legal compromise between customers installing some solar power, enough to handle their peak needs, and customers installing so much solar power they don't need the power company at all. This would save the power companies the investment in those peak-load power plants, while the customers generally simply wouldn't be producing levels of power such that they might want to sell some over the grid. The second important thing is the fact that as population rises, the need for more base-load power keeps going up. The power grid can currently handle the current-base-load plus current-peak-load, and as the overall load increases, the grid needs to be enhanced. Well, again if customers can have solar power adequate to handle their peak needs, then the power companies, by not needing peak-load power plants, can also save on investing in upgrades to the grid for a while. They would only need to do that when the total base-load production rises to equal the current total of base+peak.

If we concentrate on fusion, not fission. Today there are a number of researchers who think that the theoretical problems of fusion have been solved enough that all we need to do is invest money in actual hardware. But the existing entrenched interests keep opposing such investments. Well, that's what THEY say, anyway. But they are certainly right that fusion, when perfected, will be less problematic than fission, especially with regard to wastes.

I'm imagining ten thousand different players exploring in ten thousand different directions, and every time something is procedurally generated, it either needs to be remembered for the next player to come along to that same location, or the generator has to be super-well-done, to reach a given point from ten thousand different directions, and the same landscape/space-scape/whatever gets generated every time.

There seems to me to be a slight error in the original article. Neutrinos have been determined to possess mass. It is only a slight amount of mass, but it precludes them from being able to travel at exactly the speed of light. How close to light-speed do they normally travel? I can't say. But it is reasonable to think that the distance from Supernova 1987A to Earth should have led to a slightly later arrival time, for neutrinos, than if they had actually traveled at light-speed.

The preceding relates to another thing, the quantum-mechanical mechanism for interfering with the actual speed of light. Those pairs of virtual particles that form also have mass. That means, while they temporarily exist, they also cannot be traveling at exactly light-speed; they have to be traveling slightly slower.

Something they might not have taken into account is the "view it again" factor. Sure, the manufacture of DVDs has a significant environmental impact. But when not simply thrown away after being purchased, it means that saving a movie for a few years, and then seeing it again, does not have the same environmental impact it did the first time. It might be interesting to see how many "views" are needed to make owning a DVD a better environmental bargain that streaming its content.

Your code should be more efficient!
