Comment Free samples from the drug dealer? (Score 1) 48

Hmm... Well as a correction I don't feel like it goes far enough. It's not to personalize your feeds. It's to addict you and waste as much of your time as possible. The drug dealers are always after fresh victims, along the lines of my mutated Subject.

Many of those books talked about the free data services Facebook pushed in places like Myanmar. If you're tracking the news you already know what can go wrong.

That's the 'black' joke I was looking for along the same lines as FP.

But getting more serious, at risk of dipping my toe into insight, if we were technically ahead of the Chinese companies, then we would be able to figure out the security threats. So I see this sort of thing as mostly surrendering and admitting the Chinese are too dangerous and we have to "run away, run away" (with the usual apology to Monty Python for the abuse of the killer rabbit joke).

Not sure how my next joke works, but there was a time I felt I could trust the Chinese companies more than the American ones because everyone was looking carefully at what the Chinese were doing. Even Huawei quaked before our technical expertise? Now I feel like we can look but we can't see.

Mod parent Funny (and basically the expected joke), but based on recent books about Facebook, I'm not understanding what part of this story is supposed to be news in the sense of "new".

The thing about "opt-out" is that almost no one will bother, but Zuck can always say "It's your own fault for not figuring it out."

If this were really a personal attack, then I'd use his real nickname, but I don't know Zuck from Adam. And if I were an "effective" writer, then I'd be better at coining memes. (Latest idea along such lines versus Rumplicans versus Dumbocrats. Cowardly orange-nosers versus believers in flying elephants.)

Donut Lab's 'Solid-State' Battery Exposed As Regular Li-Ion (electrek.co) 250

A battery researcher's investigation, backed by more than 20 independent experts, claims Donut Lab's much-hyped "solid-state" battery is actually a conventional lithium-ion cell, with voltage curves and expansion data matching high-nickel NCM chemistry rather than the promised sodium-ion solid-state design. Electrek reports the company raised about $25 million from more than 1,300 mostly small investors on claims of 400 Wh/kg energy density, 100,000-cycle life, and 5-minute charging that now appear unsupported. From the report: The investigation consulted over 20 independent battery experts, including Julian Zanau from the Fraunhofer Research Institute, Dr. Yahim San from Justus-Liebig University, Tom Bicha from Leona, and Dr. Yuo Hesca from Seinajoki University of Applied Sciences. Every single one confirmed the tested cell is lithium-ion. There are two key pieces of evidence. First, the voltage curves from VTT testing match high-nickel lithium-ion cells (NCM chemistry). The cell sits at 3.7-3.8 volts at 50% state of charge -- right where lithium-ion cells operate. Sodium-ion cells don't go significantly past 3.5 volts at 50% SOC.

The second piece of evidence is even more damning: VTT's cell expansion data. When a battery charges, ions squeeze into the anode material, causing it to expand in a predictable pattern. A graphite anode produces a distinctive "kink" in the expansion curve around 50-70% state of charge, caused by how ions reorder themselves in graphite's layered structure. The Donut Lab cell shows exactly that kink.

This is critical because sodium ions are physically too large to fit into graphite layers. The graphite anode signature proves the cell uses lithium ions. The investigation puts it well: "it's like we have a slightly noisy fingerprint and a picture of the suspect's face. And yet again, it's a match." The calculated energy density? About 298 Wh/kg -- what you'd expect from a good lithium-ion cell, not the 400 Wh/kg claimed.

The investigation reveals that the battery technology traces back to CT Coatings, a German company with an "eclectic" array of patents -- including inventions for screen-printed paving slabs, menu folders, and warning triangles. CT Coatings promised Nordic Nano and Donut Lab a screen-printed sodium-ion solid-state battery. What it delivered was a lithium-ion pouch cell.

It costs next to nothing to bring on a new customer since there's no widget to make and ship.

Growing marketshare is *the* priority. Give it away for free. Pay people to use it if you must.

Then once they're hooked, start charging licensing fees. Just a little. More for bigger customers. Maybe keep a free tier for personal use. A little times a huge userbase is enormous cashflow for a little bit of nre.

It's great cuz the customer supplies his own platform, pays for training his own people, and even pays for the electricity to run your product on premises.

Now about this building full of expensive and power-hungry silicon needed to deliver the ai hotness...

Comment Compared to MAC logging? (Score 1) 66

Tracking license plates is nothing compared to tracking the MAC identifiers.

That's the joke I was looking for, but considering the current state of today's Slashdot, I wonder how many of today's visitors to the website even know that that own smartphone keeps a list of all the MAC IDs for the Wi-Fi networks it has connected to at some point in the past.

Oh, wait. I only learned about this recently.

But I suspect there are some places like China and the US of Surveillance where they are logging LOTS of MAC data. And now developing the AI systems to analyze it. Why aren't you laughing yet? You think you have a solution approach?

Hmm... Only "insightful" comment in the FP branch? Maybe the moderators have been replaced with genAIs?

(And no Funny anywhere, as expected.)

As regards the story I'm remembering a recent MIT video. Long section about how to make AI work with the course. On the negative side, it recommended an anthropomorphic approach, basically treating the AI as though it were a human collaborator, but with "usage limits" to keep it in a subordinate status. On the positive side, I forgot. Maybe I should ask an AI for help?

I'm feeling increasingly bleak about the future of humanity. We definitely need to change the reference frames of our thinking, but we humans have never been that quick on our wits. In theory I think we could learn how to think about problems at new levels of abstraction that would make the AI tools useful, but in practice the tools are changing faster and faster all the time and we are already past the point where we humans can keep up with them. They have become almighty black boxes, spewing words that appear meaningful while we have no clear idea how the words are being created.

Sam Altman's use of the same words may be more troublesome. He sometimes sounds like he understands the risks there.

Too bad there's no funny here. And the FP branch was disappointing, too. Didn't lead anywhere interesting before I lost interest in following it... Both par scores for Slashdot these years. Almost enough to make a nerd want to invite comments from a genAI: "What is the best joke for this story?"

Comment That's nice (Score 0, Insightful) 74

Hospitals don't have a fountain of money. They purchase malpractice insurance on behalf of their providers and the premiums for that insurance pay for these jury awards.

Insurance companies don't print their own money either. They redistribute the costs of these payouts over their risk pool. And those premium hikes is one of several reasons why your emergency room visit costs 10k if you had to pay for it out of pocket.

The other reason it costs 10k is that enough of these lawsuits and jury awards have forced hospitals into doing medically unnecessary (but expensive) tests for everyone, rather than coming up with some kind of cost-conscious criteria, to cover their bases and their asses so they don't get sued.

Say it with me now: tort reform. The lawyers don't like it, which is how you can tell it's a good idea.
