Submission + - Plato's final hours recounted in scroll found in Vesuvius ash (theguardian.com)

An anonymous reader writes: Newly deciphered passages from a papyrus scroll that was buried beneath layers of volcanic ash after the AD79 eruption of Mount Vesuvius may have shed light on the final hours of Plato, a key figure in the history of western philosophy.

In a groundbreaking discovery, the ancient scroll was found to contain a previously unknown narrative detailing how the Greek philosopher spent his last evening, describing how he listened to music played on a flute by a Thracian slave girl.

Despite battling a fever and being on the brink of death, Plato – who was known as a disciple of Socrates and a mentor to Aristotle, and who died in Athens around 348BC – retained enough lucidity to critique the musician for her lack of rhythm, the account suggests.

The decoded words also suggest Plato’s burial site was in his designated garden in the Academy of Athens, the world’s first university, which he founded, adjacent to the Mouseion. Previously, it was only known in general terms that he was buried within the academy.

The text also reveals that Plato was sold into slavery on the island of Aegina, possibly as early as 404BC when the Spartans conquered the island, or alternatively in 399BC, shortly after Socrates’ passing.

“Until now it was believed that Plato was sold into slavery in 387BC during his sojourn in Sicily at the court of Dionysius I of Syracuse,” Ranocchia said. “For the first time, we have been able to read sequences of hidden letters from the papyri that were enfolded within multiple layers, stuck to each other over the centuries, through an unrolling process using a mechanical technique that disrupted whole fragments of text.”

Ranocchia said the ability to identify these layers and virtually realign them to their original positions to restore textual continuity represented a significant advance in terms of gathering vast amounts of information.

Comment Re:no different than taking plastic to a landfill (Score 1) 100

'Plastic' encompasses a wide range of materials with a large range of properties. Some break down easily as you found out with your shoes, many do not and can indeed persist in the environment for hundreds of years.

OP is right in that landfill is the best place for most plastic, where it can do little harm. Microplastics are generally created by some sort of mechanical action, such as wearing and laundering of synthetic textiles or the action of the sea on plastic that's been dumped in it. That doesn't happen in landfill.

Submission + - Pentium 5 - A Rare Look Into The CPU That Could Have Been But Never Was (wccftech.com)

alaskana writes: In late 2022 it was revealed that early samples of what was to be the 'Pentium 5' processor, codenamed Tejas and Jayhawk was in development and made it as far as being released to board partners for evaluation. A few of these samples made it (of course) onto Ebay and then — not surprisingly — into the hands of a YouTuber. To be fair, tech site Anandtech arguably got the first scoop on this P4 successor way back in 2004, but that story seemingly never gained much traction at that time.

Intel Prescott CPUs could hit 5GHz+ but had huge power and temperature numbers, but Tejas was expected to clock higher than Prescott — with Intel chasing the huge 10GHz CPU clocks within 10 years between 2000 and 2011 — but it ended up not happening at all."

In what was supposed to be a continuation of the 'GHz is king' days of the early aughts, the Pentium 5 was in spirit a continuation of the 'faster-is-better' philosophy of the P4 architecture, efficiency be damned. Speeds in excess of 7 GHz(!), and a pipeline upwards of 50 stages were rumored to be targeted by Intel, but reality (and physics) reared their ugly heads as always.

Intel engineer Steve Fischer, who was involved with the project, added: "The thing had a pipeline depth of around 50 stages and an expected clock target at one point north of 7 GHz. I call the thing "the Death Star of processors" and half-jokingly reasoned that consumer acceptance of liquid-cooled chassis would not be a big deal." Intel kicked off Project Tejas in 2003, expected in 2004 and later pushed into 2005 after issues forced Intel to redesign the chip. Before the company could do that, the Tejas Project was shelved on May 7, 2004.

In the end efficiency and parallelization was to be the rule of future CPU development, but the fact that Intel had (at least briefly) had planned on taking the P4 paradigm just a wee bit further with a true Pentium 5 is a fascinating look into the past of a future that never was to be for the venerable Pentium line.


Comment Re: Drop the gas, use electric (Score 2) 297

Also switched to induction a few years ago and I disagree. With gas you can clearly see the flame, estimate the amount of heat being produced and adjust accordingly. Induction just had some numbers on a display, and heat output varies with the size of the cookware being used. I'm forever fiddling with the controls on my stove, it's always too much heat or too little.

There's a lot to like about induction; the cleanliness, efficiency and lack of pollution but controllability is much inferior to gas.

Why is nuclear a shitty option? Expensive to build, yes, but it's far more reliable than wind and solar.

The UK has the largest installed base of offshore wind generation in the world but output can and does fall to near zero, sometimes for long periods. Solar in most of Europe goes awol during the winter.

The Germans even have a word for periods of low renewable output: Dunkelflaute. The great Dunkelflaute of August-October 2021 where most of Western Europe was becalmed prompted energy shortages and sky-high wholesale power costs. There was no better demonstration of how vulnerable a grid becomes if it becomes over-reliant on renewables.

Fractions of a cent? Bitcoin fees are usually much higher than that. Gas fees on Ethereum are sometimes into three digits. Then you have to take into account fees for converting from fiat and back again.

There is also no such thing as an 'instant' crypto transfer. If it takes a couple of minutes you're lucky. A congested network means it could take hours as Bitcoin is, and forever will be, limited to 7 transactions a second.

And if you get hacked at any time the money is gone. No central authority able to help you and reverse the transaction. I'm sorry did you mean to send your coins to mfgN7bd46jK8mNnrMemGKdiWBud1YA5xwX instead of mfgN7bd46jK8mNnrMemGKdiWBud1YA5xwY? Money is gone, thanks for playing.

But apart from all that crypto is definitely the 'currency of the future'.

Submission + - Polynonce: A Tale of a Novel ECDSA Attack and Bitcoin Tears (kudelskisecurity.com) 1

Gaglia writes: The Kudelski Security Research Team just published a novel attack on the ECDSA digital signature algorithm. At a first glance, the attack is not catastrophic: As long as the randomness used in generating signatures comes from a secure source (as it should always be the case) then the scheme remains secure. However, what makes this attack dangerous is that even a slight bias in the randomness allows to perform a full key recovery attack (the most serious kind of cryptographic break) by observing just a bunch of public signatures. The authors tested their attack, among other targets, on the full Bitcoin network. Even if they couldn't break any wallets, they found wallets that had been already attacked in similar way in the past. There is an interesting followup investigation tracking these stolen funds, and also a release of open source code to test the attack on different targets.

Five years ago the flagship Nvidia GPU, the 1080 ti, cost around $700. Today's flagship 4090, which has a smaller die than the 1080 ti, is priced at $1700. Mid-range cards have experienced similar price hikes.

There is nothing to justify that other than greed and an effort to maintain the huge margins they enjoyed during the crypto boom. I've always been a PC gamer but it's getting hard to justify when I could buy a console for a third of the cost of a GPU alone.

I only hope Intel continues development of their Arc GPUs and lights a fire under the Nvidia/AMD duopoly.
