Don Quixote would be proud of how hard turnip is tilting at windmills...

I get the man dislikes them because he thinks they're ugly and mess up his golf course views or something.. but my gods we are living in the most stupid timeline

I would not normally really make "political" posts on /. but this isn't politics it's a cult of stupidity.

Something like this needs density. If there's not enough people using it, then the per use cost will be far too much to make it economically viable. That makes cities much more attractive to startups like this. Of course there you have airspace issues with large buildings, so the true sweet spot may be relatively dense but very high income suburbs. But it sure as heck won't be rural.

I came here to look for this and add it if I didn't find it.

Lunar "soil" is essentially neutral, just needs some additives. Conversely, Martian "soil" is actually poisonous. Additives alone aren't sufficient to get things to grow in it, you need to remove the poisonous parts first.

Net: It's easier to grow plants in lunar rather than Martian "soil".

Thanks for your questions, Freenet caches data but it isn’t meant to be a long-term storage network. It’s better to think of it as a communication system. Data persists as long as at least one node remains subscribed to it. If nobody subscribes (including the author), it will eventually disappear from the network. So yes, if only your node subscribes then the data will only exist there and won’t be available when your machine is offline. But if other nodes subscribe it will be replicated automatically and remain available even if your node goes offline.

Submission + - Thorny issue plaguing lithium-ion batteries laid bare in new study (phys.org)

alternative_right writes: Lithium dendrites, i.e. tiny crystalline thorns that grow off of lithium-ion battery anodes during charging, have been a persistent challenge for the world's most widely used form of energy storage. "Dendrites can penetrate the battery's separator, causing catastrophic short circuits and safety hazards," said Qing Ai, a former research scientist at Rice University who is a first author on a new study published in Science that reports for the first time exactly how these tricky structures behave inside batteries. "Despite decades of study, the fundamental nanomechanical properties of lithium dendrites remained a mystery—until now."

Submission + - New Freenet Network Launches With River Group Chat (freenet.org)

Sanity writes: Freenet’s new generation peer-to-peer network is now operational, along with the first application built on the network: a decentralized group chat system called River.

The new version is a complete redesign of the original project, focusing on real-time decentralized applications rather than static content distribution. Applications run as WebAssembly-based contracts across a small-world peer network, allowing software to operate directly on the network without centralized infrastructure.

An introductory video demonstrating the system is available on YouTube.

Slashdot previously covered the reboot of Freenet in 2023 in this article.

Submission + - Executives say AI boosts productivity but the real gain is just 16 minutes per w (nerds.xyz)

BrianFagioli writes: A new study suggests the productivity boost from artificial intelligence may be far smaller than executives claim. According to research cited in Foxitâ(TM)s State of Document Intelligence report, while 89 percent of executives and 79 percent of end users say AI tools make them feel more productive, the actual time savings shrink dramatically once people account for reviewing and validating AI-generated output.

The survey of 1,000 desk-based workers and 400 executives in the United States and United Kingdom found executives believe AI saves them about 4.6 hours per week, but they spend roughly 4 hours and 20 minutes verifying those results. End users reported a similar pattern, estimating 3.6 hours saved but 3 hours and 50 minutes spent reviewing AI work. Once that âoeverification burdenâ is factored in, executives gain just 16 minutes per week, while end users actually lose about 14 minutes.

Comment "bright as a full moon" (Score 3, Insightful) 80

You can stare at the full moon all night if you like, because the albedo of the moon has filtered most of the light including the UV band that naturally passes through our own atmosphere. The three mile circle illuminated by a mirror would bounce a significantly higher amount of UV than the moon's albedo. If you treat the 60ft reflector as an analog to a pinhole in a pinhole camera, the circular area on the Earth surface would be a rough projection of the image of the sun.

(1) I wonder how they calculate the UV exposure for the observer on the surface within the illumination area.

(2) I wonder if you'd be able to detect places in a coherent projection where sunspots or coronal ejections are reflected through the "pinhole" effect of this arrangement.
