Comment Re: Performance per Watt (Score 1) 65

Why? Search algorithms are enormously efficient and easily parallelizable, and what you can describe can be divided into stages and pipelined as well.

You also don't know all that many people, maybe a hundred, maybe a thousand tops. Even sequentially going through a list of all the external characteristics you know about a thousand people is sheer triviality for a modern computer. The dataset would be small because you're not trawling through petabytes of data but looking through already digested and organized information.

Comment Re:GPU does what? (Score 4, Informative) 65

Everything works better when specifically designed for the application. A CPU can render in software, but a GPU does it better. A GPU may mine crypto well, but an ASIC designed for crypto and nothing else will do a much better job.

AI turns out to have some quite specific needs that GPUs don't ideally satisfy: https://www.youtube.com/watch?...

Clean Jet Fuel Startup Fires Up New Carbon Converter (spokesman.com) 41

Thursday a climate technology startup called Twelve "took a major step toward producing sustainable aviation fuel..." reports Bloomberg, "by launching its commercial-scale carbon transformation unit." Twelve is among the emerging companies working on ways to transform captured CO2 into useful products. In the case of the Berkeley, California-based startup, its nascent technology will be critical to cleaning up one of the hardest-to-decarbonize sectors: aviation. Twelve uses a technique called electrolysis that uses electricity to repurpose carbon dioxide and water into various products. When the electricity is generated from renewables, the process is essentially no-carbon. The company's CO2 electrochemical reactor — called OPUS — will be at the center of its first commercial production plant for sustainable aviation fuel, under construction in Moses Lake and set to be completed this year. The plant will run on hydropower and use CO2 captured from a nearby ethanol plant. That CO2 and water will be fed through OPUS and turned into synthetic gas, the basis of sustainable aviation fuel.

Twelve's airline customers can blend it with traditional jet fuel. The resulting carbon credit can be bought by corporate customers like Microsoft to offset their business travel-related emissions...

Although Twelve's carbon transformation technology can be used to make products ranging from spandex pants to car parts, it pivoted to focus more fully on sustainable aviation fuel after the announcement of tax credits for SAF blending, carbon capture and utilization, and hydrogen production, said Twelve co-founder and Chief Science Officer Etosha Cave. Those tax credits helped the company launch this commercial unit. "Without that, we would not be competitive in terms of being able to get to market at the stage we're at," Cave said.

It's still not cost competitive with traditional jet fuel, the article points out, "but airlines are under increasing pressure from governments and their own net zero commitments to integrate SAF into their fuel mix.

"Twelve would not disclose its cost to make the fuel, though it said it expects prices to go down as its technology scales up and eventually reach parity with traditional jet fuel."

The Internet is less of a wild west than it used to be, but it's still pretty wild.

There's plenty big countries like Russia where the authorities won't care at all about any of your local rules. That may not be fun, but it's a fact. If somebody from Russia runs a scan on you, and then distributes information in Russian forums, there's pretty much nothing you can do about that.

Even less now with the Ukraine situation, where Russia is heavily sanctioned and even less inclined to be friendly to other countries.

You can't.

Even if you could obtain some compliance within a given country, the Internet is international and people from various less liked jurisdictions couldn't care less about what rules you might have.

Once the data is out there, it's out there. You can't ever have any confidence that nobody will notice that a given port is open or a given service is buggy, and that this fact won't spread through various parties, including things like underground forums most people don't know even exist.

The NeXT had two buttons on the mouse but they both acted like a left button. There was a user option defaulting to off to enable the right button. I figured software could ignore this, I was wrong the buttons were made identical deep in the OS. Steve Jobs déconstruit had a hate of multiple buttons.

How do you plan to enforce that? Remember we're talking about state level actors.

1. Buy a bunch of phones in the US
2. Ship to Russia
3. Take apart, hook up probes instead of the camera.
4. Fake the entire environment -- spoof GPS signal, spoof cell tower.
5. Produce whatever signed picture you need, that seems to have been taken elsewhere.

Sure, this takes work, but all the tooling for it is available and it's peanuts to a government, there's even small companies that own such hardware for testing purposes.

How is that supposed to work?

Russia, as much as the current government sucks, still has plenty smart people in it. If you create a signing mechanism and Russia or China want to create chaos by AI fakes, then it won't be that much effort for them to obtain phones, hack them, and sign whatever they please.

Worst case, they take the device apart, and hook up something instead of the sensor to feed the right image to the signing chip.

More likely, they'll find some hole to exploit, or even print whatever they want in high quality, and take a photo of it really carefully.

This kind of thing can't possibly dissuade a serious attacker like a government.

Comment Re:Somebody has too much faith in humanity (Score 2) 68

Bitcoin was supposed to usher in an era of uncontrolled finances where no government could impose rules on your payments and no central bank could control your currency. We can see how well this worked in almost every bloc as bitcoin regulation fills greedy government agendas.

Bitcoin failed even before regulation caught up. This whole dream was held only by a very small amount of people, who got completely overwhelmed by the "get rich quick" crowd as soon as BTC turned from a theoretical thing for nerds to play with to something that could make you tons of $$$.

And that imposed rules even worse than any government. Who elected BTC Core, or the miners? There's like a dozen guys on top of BTC, unelected and unaccountable to anyone, and yet they still get to make decisions about how the network operates.

The design for BTC was fatally flawed from the start, in that for instance it failed to realize that mining would quickly require pools, and pools concentrate power in the hands of the very few.

Comment Re:Part of the early 2000s XML solves everything (Score 3, Informative) 32

XMPP isn't even good XML. It's weirdly annoying.

XMPP absolutely requires an event-based parser, because the entire conversation from start to end is a single XML document that doesn't end until the client disconnects. So you absolutely need a parser that can deal with XML as it comes.

It's also not terribly high performance friendly. There's no clear framing, so the only way to tell where a message ends is to parse XML until you reach the end. You don't get a friendly protocol that tells you "Hey, next message is 520 bytes long", so that you can conveniently allocate a buffer upfront and read the whole thing in one go.

Besides that, it appears that XMPP's dialect deviates somewhat from proper XML, eg, by not allowing anything but UTF8 and forbidding comments. Those may be fairly minor, but they'd be problems early on, meaning you can run into trouble with the wrong XML libraries/code.

Comment Re: NFTs (Score 1) 117

Extremely awful way to live though.

In the ideal NFT-world, everything is a NFT: your movie ticket, your school diploma, your house's deed, your membership in various organizations. The same wallet is also your way to pay for anything and log in anywhere. Your entire identity is connected to this stuff.

So under a model like that every time you interact with almost anything or anyone they find your wallet ID, and obtain the ability to scrutinize what you own, where you've been, what you pay for, how much you earn... This can be used not only to grant access but to treat you as an enemy if you happen to do something that given person/org doesn't like. And they can keep track of you after that forever.

Also this allows random people to send you anything they want, including nasty stuff. And then you can't just delete it, but have to pay to move it somewhere else. But the blockchain still records all of that, so that history is there for anyone to read. And stuff people can send you includes smart contracts which can be used to execute malicious code that steals everything you own. A bit like the good old times of VBS macros spreading by mail, only in this case they can empty your account with zero recourse or possibility of recovery.
