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) 245

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.

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?

My father has been locked out of his email account since last month. Multiple calls to support and now a second ticket for support have gone nowhere. They're a bunch of script kiddies repeating the same things over and over and never listening to what is being said.

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.

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?"

Submission + - Another fine identity mess the Google has gotten us into? (creators.google)

shanen writes: Can't find any discussion of "Google for Creators", so here's a submission for ye olde Slashdot. Me thinks the essential idea is sort of good, but the idea of the google controlling it is bad. My version was kind of a public utility website where each person could anchor their identity on the Web, though I was seeing it as a way to protect identity by linking your real identities and allowing for the reporting of impersonation identities. My version of the idea broke down over the lack of a trustworthy host for such a thing.

The google's motivation is much more clear and I sort of applaud them. The google wants to have a kind of choke-point over as many Internet influencers as possible. If your identity is big enough to matter, then the google is offering to give "free" advertising. ONLY if you matter in the ways that google accepts but the real questions are "Why would anyone trust the google that much these years?" and "How is the google planning to monetize the choke-point?"

Congress doesn't have these powers.

Yes, they do. Had you ever read the discussions in the Senate about the amendments, you would have known this very subject came up. Unfortunately, his orange lardness has hidden from public view those historical records, so what I'm about to say goes from my memory.

Essentially, if Congress has the power to enact laws affecting the country, it is up to the Executive and Judicial branches to curb that power. Madison, despite opposition to the General Welfare Clause, admitted late in the life that clause granted Congress a power to legislate on all national problems. His nature of limited government was undercut by that clause, for if the national Congress could enact laws affecting the country, it wasn't a limited government, was it?

Further, as mentioned in the debates, Congress could delegate its authority. It would be inconceivable for Congress to be involved with the minutae of the country, to discuss and debate whether this or that is allowed. Instead, as granted by the Constitution, Congress has delegated its powers to others. Namely, agencies such as the FTC.

It's really hard to find these powers in such a tiny document without decades of legal training.

No it's not. All one need do is read the debates in the Senate to understand the mindset of the Founding Fathers. If you want more, reading a few books about those Founding Fathers would suffice to fill your lack of knowledge.
