It’s all encrypted in storage. The decryption key is in the secure element / TPM chip, additionally protected by your PIN / password. Shutting it down unloads all encryption keys from memory.
Beware that US customs / immigration / border control can seize your phone and refuse entry.

You can do much better than a ledger with a commitment scheme and transparency log.

No, copyright isn’t relinquished from any of that (not even any effect on damages if you still require players to have bought the game to use the private servers), and trademarks wouldn’t be affected at all if you simply require that 3rd party servers are marked as unofficial
- Comment on The signatures are still coming and it's already making an impact 1 week ago:
Only applicable if they run the servers themselves, not if they let others run their own servers.

And “would leave rights holders liable” is completely false, no game would have offline modes if it did

The Pixel line is comparable to the Samsung S line, you got a budget phone before

OTOH I only have a PS5 because of Sony’s marketing budget, lol (non-slim version included with a Sony phone on contract, so technically also a way for them to clear stock, lmao)
But yeah, I don’t know any people with a recent Xbox here in Sweden. In the original Xbox era and the 360 era I think they had a big lead here, but after that I’ve seen much more Sony represented.

I’ve heard stories of clients giving gifts getting pissed when the wrong person claims them, so it’s risky for not just legal reasons

The judge explicitly did not allow piracy here. Only legally acquired media can be used for training.
- Comment on Meta wins artificial intelligence copyright case in blow to authors 2 weeks ago:
This case didn’t cover the copyright status of outputs. The ruling so far is just about the process of training itself.
IMHO the generative ML companies should be required to build a process tracking the influence of distinct samples on the outputs, and inform users of potential licensing status
Division of liability / licensing responsibility should depend on who contributes what to the prompt / generation. The less it takes for the user to trigger the model to generate an output clearly derived from a protected work, the more liability lies on the model operator. If the user couldn’t have known, they shouldn’t be liable. If the user deliberately used jailbreaks, etc, the user is clearly liable.
But you get a weird edge case when users unknowingly copy prompts containing jailbreaks, though

- Comment on A Completely Natural Conversation in the NYC Reddit 3 weeks ago:
A reminder that “cashback” credit cards are paid for by big fees on transactions which the store pays, forcing them to raise prices. It’s literally anticompetitive

- Comment on The "standard" car charger is usually overkill—but your electrician might not know that [32:26] 3 weeks ago:
The infinitely easier solution is to let the car charger know how much power is available to draw.

I remember this lol
Tldr neural network models are incredibly weird. My best guess is that the combination of common recurring structure with variations based on common rules (joke threads and all) helps the model derive some intuition about how to handle variations of things.
Also reminds me of an even earlier neutral network which got better at playing specific games after being trained on large amounts of text completely unrelated to the game, like encyclopedias or whatever.
- Comment on An alien who sees in the radio part of the light spectrum would probably be blinded by all our wireless communications 5 weeks ago:
Massive singular radio telescopes are used to pick up individual signals from one direction, and can’t do imaging alone.
Sure you can pick up long wave radio with smaller antennas, but not without trade-offs. They often need long coils, and to make up the remaining difference you need to very precisely control electric resonance, and you lose efficiency (you pick up less energy from the radio waves). You definitely can’t do imaging with just one.
Just look at how big NFC and Qi coils are, they can’t practically be made smaller at those wavelengths, or else you lose too much energy!
Massive radio telescope arrays spanning the globe uses the massive distance to create a tiny amount of angular resolution, just enough that with months of processing you can image a black hole a few light years away with some thousands of pixels. Compare to how your phone can run deblur algorithms on a fraction of the power over far more pixels, because the angular resolution makes such a huge difference (blur radius is infinitely smaller)
