Comment Hal Finney was Satroshi (Score 4, Interesting) 91

It has been an open secret in the cryptography community that Hal Finney was the designer of BitCoin from the very start. Hal died in 2014. Or at least he was frozen in liquid nitrogen so not talking either way.

Besides being the first person to be involved in BTC who didn't hide behind a pseudonym, Hal published a paper that describes essentially the whole BitCoin scheme two years before BTC was launched. And Hal never once accused Satoshi of stealing his work.

The reason Hal had to hide behind Satoshi is simple: The Harber Stornetta patent didn't expire until about 9 months after BTC launched. That covers the notion of the hash chain. There is absolutely no way anyone working in the field did not know about that patent or its imminent expiry. Hal certainly did because I discussed it with him before BTC was launched.

So the big question is why BTC was launched when it was, why not wait 9 months to have free and clear title? Well, Hal got his terminal ALS diagnosis a few weeks prior: He was a man in a hurry.

Having launched prematurely, Hal had to wait six years after the original expiry of the patent term to avoid a lawsuit over the rights to BTC from Surety. He died before that happened.

Oh and I have absolutely no doubt Hal mined the genesis blocks straight into the bit bucket. The key fingerprint is probably the hash of some English language phrase.

Comment Re:The Inventor of Bitcoin Should Be Worth Billion (Score 1) 92

The real inventor of BitCoin wrote a paper describing the architecture two years earlier under his own name, Hal Finney. He got a terminal diagnosis of ALS a few months before he launched the BitCoin service, the pseudonym being necessary at the time because of the Haber-Stornetta patent on the BlockChain.

No, Hal, did not keep the coins. He invented BitCoin because he was a crank with weird ideas about inflation, not to get rich. Mining the coins and keeping them would have been a betrayal of his principles.

The proof of this is given by the fact that Hal did not in fact get rich from BTC despite being the ''second' person to join the project. Nor did Hal ever complain that Satoshi took the credit for what was very clearly his work. If Hal had been just another person coming along, there would have been every reason to keep the cash.

And we do in fact know Hal ran mining servers from the start and that he ended up in serious financial trouble due to his ALS. The freezing his head thing came from donations.

Craig Wright does seem to be the last of the three early advocates alive but that doesn't make him Satoshi. Wright has never shown the slightest sign of being the sort of person who builds such a thing and in any case, Hal's name is on the much earlier paper.

Comment Linus Torvalds and I both enjoyed the QL (Score 1) 124

(Comment I also added to the register article - but I like /. too :-).

I offered to go with Linus to Sao Paulo zoo once to help him avoid having to meet Lula, the president of Brasil which he really didn't want to do :-). I did so only on the condition he do an interview with me. I was fed up of people asking Linus about Linux, so I only asked him questions about the Sinclair QL, which both he and I enjoyed. Interview is still available on youtube here:

It has to do with the fact that companion dogs (pet dogs) live a lifestyle that is strongly correlated to their owners', so it's important to gather all the info about your lifestyle.

"None of these could have anything to do with dog aging, and therefore this study is not about dog aging, it's about collecting sensitive information about people for some political purpose." is quite a leap of logic there.

'What Kind of Bubble Is AI?' (locusmag.com) 100

"Of course AI is a bubble," argues tech activist/blogger/science fiction author Cory Doctorow.

The real question is what happens when it bursts?

Doctorow examines history — the "irrational exuberance" of the dotcom bubble, 2008's financial derivatives, NFTs, and even cryptocurrency. ("A few programmers were trained in Rust... but otherwise, the residue from crypto is a lot of bad digital art and worse Austrian economics.") So would an AI bubble leave anything useful behind? The largest of these models are incredibly expensive. They're expensive to make, with billions spent acquiring training data, labelling it, and running it through massive computing arrays to turn it into models. Even more important, these models are expensive to run.... Do the potential paying customers for these large models add up to enough money to keep the servers on? That's the 13 trillion dollar question, and the answer is the difference between WorldCom and Enron, or dotcoms and cryptocurrency. Though I don't have a certain answer to this question, I am skeptical.

AI decision support is potentially valuable to practitioners. Accountants might value an AI tool's ability to draft a tax return. Radiologists might value the AI's guess about whether an X-ray suggests a cancerous mass. But with AIs' tendency to "hallucinate" and confabulate, there's an increasing recognition that these AI judgments require a "human in the loop" to carefully review their judgments... There just aren't that many customers for a product that makes their own high-stakes projects betÂter, but more expensive. There are many low-stakes applications — say, selling kids access to a cheap subscription that generates pictures of their RPG characters in action — but they don't pay much. The universe of low-stakes, high-dollar applications for AI is so small that I can't think of anything that belongs in it.

There are some promising avenues, like "federated learning," that hypothetically combine a lot of commodity consumer hardware to replicate some of the features of those big, capital-intensive models from the bubble's beneficiaries. It may be that — as with the interregnum after the dotcom bust — AI practitioners will use their all-expenses-paid education in PyTorch and TensorFlow (AI's answer to Perl and Python) to push the limits on federated learning and small-scale AI models to new places, driven by playfulness, scientific curiosity, and a desire to solve real problems. There will also be a lot more people who understand statistical analysis at scale and how to wrangle large amounts of data. There will be a lot of people who know PyTorch and TensorFlow, too — both of these are "open source" projects, but are effectively controlled by Meta and Google, respectively. Perhaps they'll be wrestled away from their corporate owners, forked and made more broadly applicable, after those corporate behemoths move on from their money-losing Big AI bets.

Our policymakers are putting a lot of energy into thinking about what they'll do if the AI bubble doesn't pop — wrangling about "AI ethics" and "AI safety." But — as with all the previous tech bubbles — very few people are talking about what we'll be able to salvage when the bubble is over.

OK, so to answer my own question, the top three as of now seem to be "The Sandbox", "Axie Infinity" and "Illuvium".

The Sandbox is supposed to be something like Roblox, Axie I already tried and didn't like and Illuvium is supposed to be like an early-access RPG, I think.

Meta's New Rule: If Your Political Ad Uses AI Trickery, You Must Confess (techxplore.com) 110

Press2ToContinue writes: Starting next year, Meta will play the role of a strict schoolteacher for political ads, making them fess up if they've used AI to tweak images or sounds. This new 'honesty policy' will kick in worldwide on Facebook and Instagram, aiming to prevent voters from being duped by digitally doctored candidates or made-up events. Meanwhile, Microsoft is jumping on the integrity bandwagon, rolling out anti-tampering tech and a support squad to shield elections from AI mischief.
