The solar constant is roughly 1361 Watts per square meter. The mirror is 60x60 feet or A_mirror = 335 mÂ. The target area is about 3 miles wide or 5.8 km (assuming a square) or A_target = 5.8 mn mÂ. The mirror will be tilted at 45 degrees give or take, so we need to take the cosine of 45 degrees = 0.7071 into account. The earth's atmosphere has a transparency of estimated 80 percent in clear weather conditions. Taken together, the energy flux on the ground will be solar constant x A_mirror / A_target x 0.7071 x 0.8 which is approximately 0.45 watts per square meter. What in the world does anybody think it is good for - except burning investor money?

This report is about the effects of global warming, and we're suddenly in a debate about race and religion. What's wrong with some people?

Same like preparing food. Many people never learned or forgot how to prepare meals from scratch (from their basic ingredients) since the food industry came up with preprocessed industry food. They make a fortune while making everyone depends on their products, in particular those who cannot afford e.g. organic food. AI is the preprocessed food (literally!) of software development. And not only software development. If AI companies have their way, manyâ"or even allâ"aspects of life will be affected. They promise a better life with more spare time because machines take over the boring tasks, and what do we do with the additional spare time? Hang out in "social" media?

I also see plenty of wind turbines and solar parks in Denmark, things "nobody" does in the world.

So they don't make pizza any more, and pizza sales drops? Who could have guessed!

Thanks to simple math and physics, it can't possibly work. The solar constant is roughly 1.362 kW/m. A 10x10 m mirror will capture about 136 kW at optimal conditions. Light is reflected down at an angle of about 45 degrees, so you've got to account for this by multiplying with the cosine of 45 degrees, which is approximately 0.7. So that's 96,307 W overall, which are then scaled to an area of about 200,000 m, which is 0.49 W/m or about 500 mW/m. For 4 minutes. I guess it is cheaper to connect an old NiCd battery to the solar panel instead.

Excellent idea for creatures who are used to sleeping at night. I hope someone stops this insane idea.

What if Trump asked Bytedance to collect and provide more data of US users (kids) and Bytedance said no?

It would be nice if Altium Designer finally worked with Wine again. Does anyone know if there is something in the works on the Wine side? (Yes I know, there's Kicad and such. But Altium has some features that Kicad does not, and are cumbersome to implement. I can't, for starters.)

You can get a RP2040 and RP2350 based board e.g. from Adafruit.

All you theoretically need is adding a state-provided additional key you encrypt against. That is, formally speaking, not a backdoor, but a normal function in public key encryption, e.g. when sending messages to multiple recipients using PGP.

Excellent stuff, and a good read for people who studied PQC. Given that in the next few weeks or months, PQC-capable (ML-KEM and ML-DSA enabled) releases of OpenSSL and OpenSSH will be rolled out in most if not all Linux distros, likely in MacOS and hopefully in the mobile variants as well, and hoping that server admins will swiftly upgrade, quantum computing supported decryption may actually be over before it even starts. (No idea what Microsoft is doing but they cannot risk adversary triggered downgrades either.) Except for those cold case encrypted harddisks using less than 256 bits of key length (i.e., weaker than AES256) and all the "harvest now, decrypt later" recordings by the likes of the NSA. This stuff is lost as soon as QCs with more than, say, 4000 error corrected qubits are available. May quantum decoherence slow this process down a bit.

This must have been common knowledge for many years now.

The business model is not stupid. Potential buyers are. The speed cap to 160 km/h remains, and the few additional HP are next to unnoticeable in real-world situations. But the battery will drain faster.

Volkswagen currently offers this only in the UK, so they are probably testing the market for more penis enlargements.
