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.

What's wrong with these guys? After all, it is a fscking machine! A neuronal network indiscriminately trained with all the BS that mankind produced so far, that does not all all "understand" what a person is talking about, and that simply parrots what has the longest probability vector. Let's face it: Of all LLMs, 4o was one of the worst recently. The way it effusively praised even the most obvious nonsense made 4o virtually useless, especially as a sparring partner for discussing technical ideas. That's why I switched to Claude. But the way it effusively praised even the most obvious nonsense may be the exact reason why people think of it as a partner or safe place. It just told people what they wanted to hear. Probably the worst therapist or friend ever.

I wonder how this affects the further development of GrapheneOS, which by and large runs exclusively on Pixel 8 and 9, at least for the most wanted features.

In fact public key encryption is exactly how Signal or WhatsApp work. Each message you send gets encrypted with the public keys of all recipients. Only they can decrypt it. What the proposed mechanism would effectively do is automatically put law enforcement on BCC.

"Backdoor" and "provide a mechanism to decrypt end-to-end encryption when law enforcement obtains a subpoena" are technically not the correct framing. This is not how public key encryption works.
Rather than that, when such mechanisms are in place, each message is additionally encrypted with the public key of law enforcement before sending so that law enforcement can decrypt such a message with their private key without any further ado. This is as if you send a CC of each message to law enforcement. This is neither a "backdoor" nor "decrypting end-to-end encryption".

I'd be extremely careful with reports from this outlet. Let's talk again when this has been peer reviewed and confirmed by independent research groups.
