Comment Analog TV history: Sony Trinitron (Score 2) 26

The Sony Trinitron was one of the best consumer-grade color TV display technologies around during the life of its key patents (late 1960s through 1996).

After the patents expired, Sony couldn't charge the premium it could during the patent life. That was the beginning of the end. The switch to newer technologies sealed its fate.

Soon, AI use will be all-but-undetectable if you just look at the output.

Authors/publishers with good reputations or with reputable organizations to vouch for them might be believed when they say "I made this without AI input" but nobody else will. At least not in cases where it matters, like news reports.

Making an account "read only"/"frozen" so you don't get anything NEW in your feed and you can't post anything make sense, but you should be able to see what you've posted before and messages others have specifically sent to you.

Personally, if I ever got the ban-hammer from a company, I'd want a reasonably convenient way to download my history, including messages directed to me or to groups I am (er, was) a part of.

Comment How cell phones cause cancer: mechanism (Score 2) 60

User unlocks cell phone and looks at his feed.
Feed tells him to eat something that will cause cancer, without saying it will cause cancer.
He eats it.
He gets cancer.

"Researcher" does a "controlled study." Pretty much the same results, with a few outlyers just to show it's a "real study" and not a "rigged one."

Logically, cell phones cause cancer and now we know why!

Submission + - China's 'fizzy' method recovers 95% lithium from dead batteries with CO2+H2O (interestingengineering.com)

An anonymous reader writes: Chinese researchers have found a method to extract lithium from used lithium-ion batteries using a mix of carbon dioxide (CO) and water. This process is safer than others that involve harsh acids and harmful chemicals, allowing for the reuse of leftover metals while also capturing carbon dioxide.

The first step is to use CO and water to gently dissolve lithium from the batteries. The CO reacts with water to form carbonic acid, which is a very weak acid, a bit like fizzy water.

This, the researchers explain, is just strong enough to pull lithium out of the battery cathode. This resulted in over 95% lithium recovery, which matches harsh chemical methods.

The second part involves the use of cathodes that contain cobalt, nickel, and manganese. Following the process, instead of discarding them, the new method “upcycles” these materials into useful catalysts.

Those catalysts can be reused in energy and chemical reactions. Throughout the entire process, the CO is permanently locked away too.

This is achieved by some of the CO ending up chemically bound in solid by-products. That means carbon sequestration, not emissions.

Interestingly, unlike traditional methods, the new lithium recovery process is able to run at room temperature and normal pressure. No grinding agents or added leaching chemicals are required, making it safer, cheaper, and easier to scale.

“Conducted under ambient conditions without additional grinding aids or leaching agents, this method minimises environmental impact,” the research team explained.

Comment AI will match 2025 jr. programmers soon (Score 1) 44

Hopefully future jr. programmers will be doing things that 2025 jr. programmers only wish they had time to do.

Remember, in the early days of programmable computers, a programmer turned a math professor's instructions into machine code, which was far "simpler" (by today's standards) than modern "programming."
