That woudl be pretty unrelated. If you use Helium and not Nitrogen, its not due to the critical temp but due to Type I or II supercondutivity.

Tcs of Superconductors have been far above liquid Nitrogen for 30 years

The difference is that if NSA manipulates all hardrives, that would be easier to spot. I know that some organizations actually check the firmaware of devices before they use these.

By the non-buy list of the

If they do do what they did up to now (namely patching some high-profile targets) it wil ltake years before it is discovered and analyzed.

should be that firmware is firmware. Please test rudimentary blocks of computing devices before you produce 100 of millions of a series.

I expect the manufacturer actually does something like a read/write test for typical conditions.

I may even accept or wish to get HDs which are one year behind SOTA, if they were not pushed out of the door in whatever shape the SW is due to a marketing deadline.

For such device i happily would pay more, if the "programmable" fuses are set/burnt.

Sounds reasonable. But the gold is just to bright to be black in any light. At most its is a 50% or so gray.

The interesting thing is however the reminder that different people may see colors differently.

Paint a sphere black, and it gets hotter than a white sphere. Emitting CO2 makes the Atmosphere "black" in the infrared, thus you increae the energy input to the system.

If the local effects have a little bump or not does not matter to the fundamental equation.

Nowadays we use modeling with great success. The models which were used to procude the processors you type on are complex. The planes you fly in are modelled. The controller in the stabilization system in you car was modelled.

Should you severly doubt that for something (globally long >100years, not locally) as simple and an energy conservation equation is not reliable, is suggest that you dont use a plane, dont use a car, and move into the forest.

That is an effect from the picture sensors and optical brighteners (which give white a blue/violet tinge from converting UV to visible). However I am completely mystified as to where anybody sees black. The small horizontal stripes?

I am not worried if humanity survives, but if you look into history, provoking wars was never a good idea.

What happens if, e.g. China falls apart in an uncontrolled fashion, or Russia, or India? Or even the US? limate change is a economic risk on a global scale.

I hope that this does not happen withing my lifetime.

Only question is the speed.

If you change something over 10000years, ok people will move and adapt.

If you change the same thing over 100 or 200 years, you may have a period of an increased numer of wars.

It is just the exposure to unsavory ideas that changes that later for far too many people.

The problem with that is in your email app. My personal experience is that I did need to work about 2 hours (distributed over a year or so) to get GPG integration in Mutt to work right, but it has worked nicely for the last 5 years or so.

Indeed. Moxie is quite good. But he is wrong here: GPG/PGP is about as simple as you can be and still offer strong security. It can be put into wrappers for a little decrease in security and some increase to usability, but that is it. In security, you cannot make a hard task simple. That is not possible without massively decreasing security.The same thing happens when you say learning to read and write is too hard. Sure, speech recognition and synthesis does allow some help, but you will never be able to use a pen or a keyboard, and it does not help you at all with deciding what to write and what the meaning of some text is. This is a hard task as well, and cannot be automatized away.

The fact of the matter is that it takes real effort to learn to use encryption securely and that nothing can be done abut that.

My "not at all" was regarding the mothers blood flowing through the child, which it most decidedly does not as that in many cases would kill the child and possibly the mother. Mothers and their children are not necessarily compatible blood donors.
