SSDs aren't just that simple. All of them have at least some SLC area, usually as cache, that's in base 2. But the rest of the SSD can be SLC base 2, MLC base 4, TLC base 8 or even QLC base 16.

And overall it's still base 2 because each SSDs pretend one block of base 4 is just two blocks of base 2, and accordingly they pretend a block of base 16 is just 8 blocks of base 2 storage.

ESS is a product built on top of a precisely tuned synapse with custom additions, but it's still synapse underneath.

NIF can't really ever reach Q>1. All the statements of having reached that only include the energy that reaches the capsule. The energy the lasers actually use is orders of magnitude larger.

This theoretical Q>1, where the plasma emits more radiation than it receives, have been reached by other reactors before.

But while tokamak or stellerator designs need a 2-3× improvement to produce more energy than the entire system needs, the NIF would need a 100-1000× improvement to reach that point, which is wholly unrealistic with our current understanding of physics.

If you actually calculate the maximum speed at which information can travel before causing paradoxes, in some situations it could safely exceed c.

For two observers who are not in motion relative to each other, information could be transmitted instantly, regardless of the distance, without causing a paradox.

The faster the observers are traveling relatively to each other, the slower information would have to travel to avoid causing paradoxes.

More interestingly, this maximum paradox-free speed correlates with the time and space dilation caused by the observers' motion.

From your own reference frame, another person is moving at a speed of v*c. The maximum speed at which you could send a message to that observer, without causing a paradox, looks something like c/sqrt(v) (very simplified).

Sure, it'd be a solution for five minutes until someone delids the secure enclave on the gaming card, extracts the keys, and builds their own open source hw alternative.

High-performance FPGAs are actually relatively cheap if you take apart broken elgato/bmd capture cards, just a pain in the butt to reball and solder them. But possibly the cheapest way to be able to emulate any chip you could want.

Element has the same costs as Signal. So far, Element has been lucky in being able to raise money by selling support contracts to governments or companies using Matrix, but even that isn't enough, which is why Element has been raising money for the Matrix Foundation for almost a year now (with little success).

That just sounds like you need more enforcement against fake subcontracting.

"completely different environment", ah, since when is Lemmy US-only?

He also uses his own http server that in turn queries the ldap server solely for the articles. The rest is compiled into the http server binary.

Tbh, das meme hat mich auch ziemlich gestört.

The big issue I see with YouTube premium (though I'm a paid subscriber) is that the bitrate is still far too low. Vimeo provided much better quality a decade ago for paid users and so do Nebula, Floatplane and all the other competing sites nowadays

There's no provider that's going to be more safe than Hetzner, tbh.

If a provider doesn't comply, you'll just get special services raiding their DCs instead.

And if you switch to a VPS provider, you're even more exposed.

Set up CAA with proper restrictions, enforce CT for your clients and use proper full disk encryption to prevent them from placing implants on your server itself.
