fgoesbrrron A new quantum algorithm for classical mechanics with an exponential speedup

People were predicting solar eclipses thousands of years ago with no calculators or even a modern understanding of math. Can't be that hard.

fgoesbrrron A new quantum algorithm for classical mechanics with an exponential speedup

> Further, we use this mapping to prove that any problem efficiently solvable by a quantum algorithm can be recast as a problem involving a network of coupled oscillators, albeit exponentially many of them.

Is this a new result, giving that quantum field theory is described in terms of quantum harmonic oscillators?

fgoesbrrron Virtual Machine as a core Android Primitive

I don't know about Android, but AMD CPUs support encrypting regions of physical memory with different keys which are accessible only to one particular VM running, but also not accessible to the host:

AMD Secure Encrypted Virtualization (SEV)

fgoesbrrron Largest tokamak fusion reactor powers up

I thought ITER was the biggest tokamak.

BTW, what is the status of ITER?

fgoesbrrron New theory claims to unite Einstein's gravity with quantum mechanics

They mention 20 years in the article.

fgoesbrrron 10,000TB storage cartridges could become mainstream by 2030

Language is defined by it's usage.

If enough people make one particular "mistake", eventually that mistake becomes the "correct" usage. See "literally" as an example:

fgoesbrrron 10,000TB storage cartridges could become mainstream by 2030

2 million laser beamlets sounds very expensive, depending on how they generate them.

It could be that the "writer" costs $1 mil right now, so might only make sense in a data center.

fgoesbrrron Chrome's next weapon in the War on Ad Blockers: Slower extension updates

They can claim dynamic fetch is "phoning home" and a user privacy danger.

fgoesbrrron A medieval Gothic monastery built using CAD / CAM

I was told we can't build like that anymore.

fgoesbrrron Emacs and the mouse: A modest defense of the rodent

Today mouse is 2 different things: actual mouse or trackpad.

fgoesbrrron Cisco aids Ukraine defense with modified switches to counter Russian attacks

It's about scale and speed, not novel attacks.

Also exploitation. An AI could determine much faster what might be worth stealing reducing mitigation time.

fgoesbrrron At Meta, Underage Users Were an 'Open Secret,' States Say

Sounds like one excellent solution is mandatory ID check on all sites which handle personal information, right?

fgoesbrrron Availability and Use of F-35 Fighter Aircraft: An Update

> Once the skies are clear

The problem in Ukraine is that the ground is not clear (mobile air defense and MANPADS). So neither side is using planes for CAS.

fgoesbrrron Availability and Use of F-35 Fighter Aircraft: An Update

Poland is buying South Korea tanks and artillery. It's also buying US tanks indeed, but your theory seems to imply that it shouldn't buy SK at all.

fgoesbrrron Availability and Use of F-35 Fighter Aircraft: An Update

If you look in Ukraine it's not the "masters of one" planes proving most useful.

fgoesbrrron Availability and Use of F-35 Fighter Aircraft: An Update

It's a complete success.

There is an order backlog of hundreds from various countries, and due to economy of scale the price went down significantly ($200 mil -> $80 mil)

French is upset that EU countries are ordering this instead of an EU made plane.

It's the right plane at the right time (Ukraine war, EU militaries pathetic state)
