4·19 hours ago10 times as much as gold
To -make-, yep. As the article pointed out, there’s a lot of Amercium in waste dumps where old smoke detectors … and anyone can make it. Five times the half-life means it can power much longer missions.

Firefox@lemmy.ml•Introducing AI, the Firefox way: A look at what we're working on and how you can help shape it | The Mozilla BlogEnglish
2·5 days agoI’m already seeing sites telling how to block FF’s AI baby steps … which I discovered were already present in the FF I use. https://equk.co.uk/2025/10/28/firefox-forcing-llm-features/
Who knows how badly they’ll mess themselves up by not being -completely tranparent- about this stuff and -not- making it really easy to disable. It’s still possible to download older versions of FF to fall back on … in case they lose their minds.

Maybe there’s something better than civilizations (not that we’ve ever had one yet) and they figured that out and are too blissed to listen.

20·15 days agoYep, I noticed that, you’re right. And that’s near-miraculous efficiency. The maker’s website sez: “YASA also estimates that its all-important continuous power will be in the region of 350kW-400kW (469bhp-536bhp).” It also sez: "To achieve a 750kW short-term peak rating and a density of 59kW/kg … " Devi’ls in the details … The image on the ‘superblondie’ page shows A LOT of cooling built into whatever metal that is: https://supercarblondie.com/wp-content/uploads/YASA-tiny-electric-motor.webp

81·17 days agoIt was a decent summary, I was replying when you pulled it. Analog has its strengths (the first computers were analog, but electronics was much cruder 70 years ago) and it is def. a better fit for neural nets. Bound to happen.

51·17 days agoNice thorough commentary. The LiveScience article did a better job of describing it for people with no background in this stuff.
The original computers were analog. They were fast, but electronics was -so crude- at the time, it had to evolve a lot … and has in the last half-century.
The Moon never gets more than 5.14 degrees away from the path of the Sun (called the ecliptic).
In the northern hemispherre summer, your side of the Earth is tilted TOWARD the ecliptic during the day (23.4° at most), and AWAY from it at night.
In the northern hemispherre winter, it’s the other way around, because the Earth’s at the place in its orbit which is tilted (23.4° at most) AWAY from the Sun during the day. It can take a long time to get this all sorted out … If you’ve got a globe and light bulb, that helps …
but the Moon’s path is ALWAYS near that of the Sun.

Wouldn’t it be great if all your docs were stored out in the cloud? Just think, you wouldn’t need a hard drive! And someone else could guard them for you, like, say, Deputy Dan. http://descope.kwwhitaker.com/wallofscience.html

















Good point on the lubricants, but given the potential profits, it’s already being worked on. https://www.nyelubricants.com/space
