Re:A 3D fruit fly on macOS desktop powered by the real FlyWire connectome on Wednesday August 19, 2026 @01:44AM (#49357350)

unbelievable amount of coarse graining to get from a real fly to this. same leve of ethical quandary as giving your dog a stuffed bear to tear apart. besides, you should see the things we do to real flies...

cursor input get scripted into loom input to the LC4s which are evidently simulated faithfully enough to drive giant fibers, which is actually how fly escape behavior works. what more could you want

wiki article states "Up to 10,000 TWh/yr of power could be generated from OTEC without affecting the ocean's thermal structure". which converts to about 500GW which... isn't that much

68 years ago we already had fission plants. the engineering side of energy production has been solved since then, it's all political now

Re:NORAD's Cheyenne Mountain Combat Center, C.1966 on Monday October 27, 2025 @02:09AM (#45717876)

not at all realistic, awful movie. somehow even worse than annie jacobsen's book. they would not fire only 2 interceptors, and there is no urgency to retaliate when it is not a decapitation strike

Re:California invests in battery energy storage, leaving rolling black... on Saturday October 25, 2025 @09:24PM (#45708335)

and there was a huge fire at the moss landing plant which left heavy metals and god knows what else raining down onto sensitive marine mammal habitat. kayak up elkhorn slough and you'll encounter dozens of otters, seals... less than a kilometer from the battery plant.

I don't think we're going to be appreciating the environmental consequences of that accident for years. heavy metals don't decay, they'll be there forever.

a pox on david brouwer and his faux environmentalism, and the politics and economic machinations that ever proposed solar and batteries as an alternate to baseload fission plants. (in fact brouwer did his damage long before solar was ever practical, so he has even less ground to stand on)
