I live here too. I'm biased, but 1) this place is not full of awesome engineers, it's mostly full of overworked contractors and newbies with eighth grader syndrome. And 2) you can't just walk up to them and ask them to explain everything about their project. That's a huge security issue and if it were true it would be a lot easier to social engineer places today. Not to say that it isn't possible, but this comment pa…

What is "eighth grader syndrome?"

Pretty sure that term doesn't apply here correctly fwiw. My best guess is that it means GP is saying that the devs in SF see themselves as overpowered/magical in their dev abilities. But it seems like a stretch of the meaning of this term as far as I have seen it used.

I'm sure this could be done, today, much more elegantly, flexible e-paper is available without being attached to some heavy clunky PCB, and flexible PCBs are easily do-able, you only need a fairly small/simple mcu and power the whole thing by inductive loops. I reckon you could probably get something close to the size/feel of a credit card, if not more bendy/flexible.

(you might even be able to get away with a tiny capacitance to hold enough power to reset the display to a 'back pattern' when it's removed from the inductive loop 'board', depends on the mcu I guess).

A button to update the card shouldn't be needed, you can detect it via whatever NFC you're using.

I don't know. I think the younger 20-somethings all have this same kind of dream, but the older people get, the more comfortable they seem hiding behind NDAs at FAANGs or staying in "stealth mode." They really don't owe anyone anything. Disclaimer: I'm one of the younger 20-somethings.

You don't "hide behind" NDAs. Either you have one or you don't. Whatever your position is on the NDAs in general, you really shouldn't break one you accepted.

The recent OpenAI non-disparagement agreement ex-employees were forced to sign was itself covered by a non-disclosure agreement. Which current employees thus naturally had no idea about... until they were leaked to the press. Would it really have been better for these not to have been leaked?

If it's in the territory of ex employees being forced to sign something, I don't count that under NDA anymore - it's just sneaky BS. You can twist anything in some evil scheme - that doesn't mean the original thing itself is bad.

The context here is sharing general technical knowledge, not the openai internal backstabbing.

Yu-gi-oh exists though, there are lots of tournaments around the world and even world championships. The game is pretty similar to the one played in the anime, if not the same

If you, exclusively, can control the rarity and issue new cards then it's hardly a decentralized market and there's no reason not do just make it a centralized system.

It's still a decentralized market, it's one with a single issuer, as many buyers as want cards, and as many sellers as wish to sell. Much like, for instance, Magic the Gathering. Not a lot of point in selling rare playing cards when they aren't rare, so sure, you could set up a token contract where anyone can issue as many "cards" with whatever properties they'd like. But that wouldn't produce a fun game. I've person…

I didn't mean people who work at Uber explaining how their load-balancing works. I meant walking up to a super cool music visualization at an outdoor art festival and they guy there happily explaining to me their entire system built out of a node flow diagram implemented on Max but adapted to visual graphics using a plugin called Vsynth. Or going over to a friend's house and seeing their modular synth system and they…

That doesn't seem very bay-specific, any DIYer will happily talk about their project.

I've heard that switching to all of that will add 20-40 seconds of dead time waiting for the display to change, as the NFC transfers power to run the whole procedure. That'd be too long an interaction time with no feedback.

And of course the cost goes way up.

No way, the real Yu-gi-oh is played with hologram projectors and the cards have personalities. Plus the rules aren't ever quite explained.

It sounds like you're very angry about Magic the Gathering.

You should take that up with the Wizards of the Coast. I've never seen the appeal myself.
