There are many legitimate reasons to track Elon Musk's flight coordinates, for example to offer him ads more relevant to his interests

I hope no one minds, but I will probably go a bit more technical on Mastodon than on Twitter, since it seems the public here is a bit more specialized. If something is not as clear will do my best to explain either case.

#TikTok sammelt fleißig Telefonnummern und zieht daraus Schlüsse, wer mit wem vernetzt ist. Besonders eindrücklich zeigt das eine Funktion namens „Du bist in den Konten in dieser Person“. Plötzlich taucht im Feed das Vide

Datenschützer*innen warnen davor, die eigenen Kontakte leichtfertig freizugeben. Mein Bericht @netzpolitik_feed mit Einschätzungen von @wchr und @noybeu.

The collapse of a startup leaves implanted medical devices in > 700 people

The unavailability of the proprietary SW needed to recalibrate the devices and maintain its effectiveness, and the draining of batteries, will leave them without treatment and with HW implanted in their bodies

They have to hack their own implants

And it is not an isolated case but a trend

absolutely dying for the color pallet used in #sable, hadn't played this one before, just picked it up this weekend, and it's a total vibe

give it a look https://store.steampowered.com/app/757310/Sable/

(ps: not an ad despite sounding like an ad, a genuine share i swear!)

((pps: if you have any recs of similar games with similar vibes please share!!! abzu, journey, the pathless all come to mind for others))

Quantum tunneling is standard textbook exercise, where a wave packet (representing the probability for a particle to be at a certain position) is able to pass through a potential barrier that classically would stop it. It is always solved (for very good reasons) in the energy domain, while its time evolution is usually neglected.

I'm seeing headlines like "Scientists just made a wormhole to learn more about traversing space and time" in response to this recent Nature paper:
https://doi.org/10.1038/s41586-022-05424-3

In fact, from what I can tell, they ran a computation on a quantum computer that would correspond to a certain quantum field theory if you expanded it from a limited number of quantum bits to an infinite number. And that quantum field theory has a conjectured relationship (duality) to General Relatively in 1+1 dimensional Anti-De Sitter space (which is neither the dimensionality nor geometry of spacetime that we actually inhabit). They did a calculation on the quantum computer that should approximate a quantum teleportation in the field theory, which (if the conjectured duality is true) should correspond to traversing a wormhole.

Now, I think that's an interesting result, but I also think it's being way overhyped to the public, and people are imagining that someone has built a literal wormhole in their lab. I suppose there's a certain symmetry, though, since I have always thought that the name "quantum teleportation" over-hypes that technology and gives laypeople a totally incorrect, Star Trek-y impression of what's happening.

@monotrox99 right! Like if it looks like pain, walks like pain, and you can't tell if it's not, then act like it is

This Universe Today one seems like the most balanced take yet, but basically agrees with (and quotes) Woit. We're talking a simulated wormhole.
