Yes we use proxmox qemu kvm with own own code for what doesn't come out of the box. qemu kvm is just as good as anything out there. Proxmox comes with a lot already included and you can run it for free and get updates for free if you enable the dev repository for proxmox packages while the bare metal host is mostly debian running with an optimized proxmox kernel.

You know Starlink and the ISS are in different orbits right?

You know that as orbits decay the satellites move to lower orbits, right?

Starlink operational orbits are (slightly) higher than the ISS orbit. If they stop being operational, they will move through successively decreasing orbital altitudes, including orbits that intersect the ISS orbit. (But note that "intersecting the ISS orbit" does not necessarily mean "intersecting the ISS".)

Yeah, that's not really a thing in LEO where debris clears itself fairly quickly due to atmospheric drag.

A Kessler event is not precluded from LEO. Give a rogue state a rocket, doesn't even have to be a large one, just capable of launching say 100 pounds of sand or little ball bearings, and place it in a retrograde orbit. and release the payload.

Deliberate antisatellite destruction is something we reasonably ought to worry about, but it is not the same thing as Kessler syndrome.

Comment Deflation [Re: Nothing backs it] (Score 2) 110

I think that deflation is overhyped.

Wow, I've never heard anybody suggest this. Deflation is almost never discussed; it's hard to consider it "overhyped" when nobody thinks about it at all.

There's a reason nobody cares about it these days: deflation simply isn't a problem with government-issued fiat currency. If there's not enough currency in circulation, just print more, problem solved. There are many problems that you can't solve by simply printing more money (or, more accurately, problems of which if you try to solve them by printing more money you create worse difficulties), but deflation is the one case where it works, and as a result, deflation just doesn't happen any more.

I'm afraid the rest of your comments don't address money supply, so they're not really relevant to a discussion of inflation and deflation. Remember, currency is not value in and of itself. It is a medium of exchange. If there's too much currency, the currency loses value, and it becomes useless as a medium of exchange: that's inflation (and, in its worst form, hyperinflation. If there's too little currency, however, the currency becomes overvalued, and stops flowing because people hold it rather than spend it. That only happens in a system in which currency can't be added to the system, but if you have such a system, it fails.

The value of money is determined by the economy that underpins it. That is why the US is hell-bent on ensuring that the dollar remains the currency for international oil trade. That's also why governments can print a little extra money without triggering inflation, if there is economic growth.

In fact, the government has to print more money if there is economic growth. Ideally, the money supply would grow exactly as the economy grows.*

*Unless the velocity of money changes.

And also an inflationary currency is a very bad thing.

I agree with your points completely, but just as a pedantic note, when the value of a currency increases, this is deflation, not inflation. Inflation is when the price of goods, measured in currency, increases. So if the price of currency goes up, that's negative: deflation.

Deflation turns out to be actually very bad, because it means people would rather hold currency than spend it, and that kills the economy. Fortunately, the deflation of bitcoin doesn't kill the economy because people simply use other things as currency.

(William Jennings Bryan's famous "Cross of Gold" speech of 1896 was in some ways about deflation: the supply of gold, which underlaid the dollar back in 1896, couldn't keep up with the growth of the economy, and the fact that the currency was increasing in value was killing farmers.)

Not true anymore, this was very through from java 1 to java 8 although.

and most existing Java 8 code would continue to work unchanged in Java 25.

No, you will almost need refactoring in 95% of cases. I spent quite a bit of time on that.

Sun stopped supporting and providing the javax.* packages and they've been replaced by the jakarta.* packages. Java finally started to remove deprecated packages, classes and methods after java 8 so refactoring is not only a matter of renaming the imports. You will also need to upgrade most of the external libraries you use for that reason and they have their own specific changes too.

In the case of a neutrotic fusion reactor, it's going to produce some radioactive cladding and that's about it. Nothing compared to fission reactors. Once they crack hydrogen->boron fusion it's over!

I love the idea of p-11B fusion, but do keep in mind that a Boron nucleus has five times the charge of a hydrogen (including tritium) nucleus, and hence five times the ignition barrier.

D-T fusion is hard. p-11B fusion is harder.

Solar's price decline by economies-of-scale is a real breakthrough we already have and should be using much more of; something Jimmy Carter should've pushed and invested in because the US is way, way behind but rapidly advancing with multi GW projects here and there.

Not sure what you're referring to here; Jimmy Carter most definitely did push for and invest in solar. Pretty much all of the solar array technology we see today is the outgrowth of the Energy Research and Development Administration (ERDA)'s research program of the late '70s and '80s. Most particularly the Large Silicon Solar Array (LSSA; later Low Cost Solar Array, LSA, and then changed to the Flat Plate Solar Array, FPSA) initiative pushed the movement of research from single cell development to production lines to actual large fields of arrays.
