Forget Ryssian involvment in Syria and Libiya!

Not true, food shopping cost in Germany are way less then in the USA and in my dense neighborhood >20.000 people/km² I have 3 supermarkets (also baker, butcher, etc.) within 5 min bicycle ride.

looofooo0on US Streetlights Are Turning Purple

Well we cannot manufacture orange LEDs with good efficiency.

looofooo0on US Streetlights Are Turning Purple

What is the normal sense of the word? I only know the CIE standard observer to define colour and with this it is clearly in the equivalence class of orange.

looofooo0on Start your own Internet Resiliency Club

Well you entering deep level of game theory here. Can you distinguish the decoy from the real and what resources you need to spend (e.g. LoRa device in a home)? How much is the signal that you can deploy decoys worth? Isn't deploying decoys below some noise level of frontline drone activity and the enemy cannot learn nothing? How many shells do you need to destroy a decoy? How certain you are about the destruction?

If it is that easy to become an artillery target, you can use it to your advantage. Randomly place LoRa devices in area near the front (by autonomous or fiber optic drone drop to decrease risk). Switch and off by some random timer and see the enemy deplete its shells and drones.

looofooo0on Maximizing Battery Storage Profits via High-Frequency Intraday Trading

so you're installing a resistive heater? what is the economics of that?

looofooo0on Maximizing Battery Storage Profits via High-Frequency Intraday Trading

500kw is nothing, that is 1/3000 of the nuclear power plant electric output.

Good luck trying to get rid of such an amount of heat anyway near your batteries.

looofooo0on We’re secretly winning the war on cancer

All these things people claim in the comments section seem like not very rigorous. Also, any increase in cancer cases has to be corrected for overweight people in the US.

There is also a lot less toxic chemicals around nowadays such as flame retardants, DDT, lead (petrol), asbestos, PCB etc.

Any statistics on this claim?

looofooo0on Why does Apple make a minority of developers finance the entire App Store?

Sure and if you buy it from somewhere else your Ford refuses to drive with them.

looofooo0on A deep dive into self-improving AI and the Darwin-Gödel Machine

I think they completely misstated in the original paper what they did. It was a tensor decomposition of complex of 4x4 matrices up to the factor 0.5. Which is a nice result, but it is not really anything practical for a computer program doing 4x4 complex matrix multiplication.

looofooo0on When the sun dies, could life survive on the Jupiter ocean moon Europa?

We just build an L1 Solar park for micro g manufacturing of space mined materials.

looofooo0on A deep dive into self-improving AI and the Darwin-Gödel Machine

"Mathematical breakthroughs: Most notably, it discovered an algorithm for multiplying 4x4 complex-valued matrices using just 48 scalar multiplications, surpassing Strassen’s 1969 algorithm"

Again despite all the AI no one found the paper which gives the best bound to this (46):

Lol, poor you.

Why do people take multivitamin any how?

Fun fact: dont eat polar bear liver, you will get vitamin A poisoning.

looofooo0on There Is No Diffie-Hellman but Elliptic Curve Diffie-Hellman

Torvald claimed:

"So that was one of the issues. But one of the issues really was, I knew I needed it to be distributed, but it needed to be really, really stable. And people kind of think that using the SHA-1 hashes was a huge mistake. But to me, SHA-1 hashes were never about the security. It was about finding corruption.

Because we’d actually had some of that during the BitKeeper things, where BitKeeper used CRCs and MD5s, right, but didn’t use it for everything. So one of the early designs for me was absolutely everything was protected by a really good hash."

sha-1 in git was just supposed to catch corruption, it was never intended to be used for security.

looofooo0on Death of Michael Ledeen, maker of the phony case for the invasion of Iraq

Meanwhile, China is outproducing the USA in ships by 1 to 100. Add steel electronic manufacturing, robots, drones, batteries etc. to it and the 'war on terror' actually lost the USA the global dominance

looofooo0on Death of Michael Ledeen, maker of the phony case for the invasion of Iraq

Meanwhile, they outsourced manufacturing to China, which is kind of insane. China builds 100x ships then the US. Add drones, steel, telecommunication, batteries, renewable to it...

looofooo0on Is TfL losing the battle against heat on the Victoria line?

The trains probably push a lot of air around. Wonder whether closing off sections with doors would help to push air out at one point and pull it in at others.

looofooo0on Is TfL losing the battle against heat on the Victoria line?

Even Kelvin is the wrong model. What we need is temperature, humidity and air speed to interfere anything meaningful. ISO 7730 is even more precise. Any meaningful discussion should use the models from there.
