Comment Re: How stupid do you have to be? (Score 2) 143

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.

Comment A partner? A safe place? A soul? (Score 2) 61

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.

Comment Not a "backdoor" or cracking encryption (Score 2) 32

"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".

Comment Who writes such headlines (Score 3, Interesting) 69

When I read about this finding 2 weeks ago, I couldn't help asking myself "who writes such headlines". It it completely bogus. In space, by definition, there is no preferred up or down, left or right, front or back, clockwise or counterclockwise. These notions are always relative to the observer. OK, in this case it's us. But they are never absolute, which is why that makes no sense. Rotation of a body is mathematically defined by its rotation vector. If you look at a rotating body and the rotation vector points at you, you see the body rotating CCW, and CW otherwise. This is what other commenters refer to as the right-hand rule. If you bend the fingers of your right hand and point the thumb at you, the fingers point in CCW direction. What the article says is that it appears that most galaxies within the sample seem to have a rotation vector which has a radial component pointing away from us, which you can easily visualize by pointing the thumb slightly away from you. But the notion of CW or CCW is entirely bogus in this example because it depends on your aspect angle. If we were to watch a galaxy rotating "CW" from the other side, it would be seen rotating CCW. It appears the author of this article does not trust his readers with this spatial imagination, and everyone else copied the headline without thinking. And while we're at it - the doppler shift does not make a galaxy appear brighter or dimmer. Instead, the part of a rotating body moving towards us (or rather, the part whose motion vector has a radial component pointing towards us) will be blue shifted, the other part red. This is how we can determine the rotation of a galaxy to begin with. Duh. Anyway - the finding, if statistically confirmed, would be interesting enough without this fuzzy clickbait. However, one would have to check if a potential preferred direction coincides with the anisotropy that has been known for long for the cosmic microwave background. Everything else (we're inside a black hole etc.) is theoretical astrophysics speculation which can hardly ever confirmed by actual observations.
