andbbergeron MUNI Heritage Weekend in San Francisco

every weekend is muni heritage weekend while they continue to operate the F as a museum

andbbergeron A 3D fruit fly on macOS desktop powered by the real FlyWire connectome

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...

andbbergeron A 3D fruit fly on macOS desktop powered by the real FlyWire connectome

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

andbbergeron The 11 Types of Washington, DC, Metro Station Architecture (2018)

both to facilitate flying junctions

andbbergeron U.S. science is in chaos

this exists and the chump is howard hughes

andbbergeron There Will Be a Scientific Theory of Deep Learning

https://en.wikipedia.org/wiki/Universal_approximation_theore...

the better question is why does gradient descent work for them

andbbergeron 3.4M Solar Panels

or we could build like 200 more fission plants and rewild all that ethanol land. not really a compelling point in favor of solar land use this factoid...

andbbergeron Live: Artemis II Launch Day Updates

ok sure but are humans a full decade of NSF budget better than robots

andbbergeron ArXiv Declares Independence from Cornell

there is. bioarxiv.

andbbergeron Ask HN: What are your best purchases under $100?

a good mission burrito is like $10 and makes my life better

andbbergeron Kidnapped by Deutsche Bahn

yes the US is laughably corrupt

andbbergeron CATL expects oceanic electric ships in three years

certainly there exist nuclear ships with enough power but I fail to see how you would feasibly tug a train of containerships

andbbergeron Mechanical power generation using Earth's ambient radiation

oops. yes. still not that much though. i mean it's a lot but it's "one more large industrialized country" a lot not "kardashev 2" a lot

> Is this not just a cellular automaton?

andbbergeron Mechanical power generation using Earth's ambient radiation

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

andbbergeron The time has finally come for geothermal energy

they're in big concrete containers rated to withstand everything its fine

andbbergeron Using Antigravity for Statistical Physics in JavaScript

this... is not very good for an hour? i would expect an undergrad to be able to cook this up in an hour

andbbergeron The time has finally come for geothermal energy

that seems fine

andbbergeron The time has finally come for geothermal energy

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

ah yes, direct democracy in california has famously never led to anything bad happening.

andbbergeron California invests in battery energy storage, leaving rolling blackouts behind

farming requires a _lot_ of water.

andbbergeron NORAD’s Cheyenne Mountain Combat Center, c.1966

the movie would be over after 10 minutes if GBI intercepted why would you assume this is an accurate depiction

andbbergeron NORAD’s Cheyenne Mountain Combat Center, c.1966

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

andbbergeron California invests in battery energy storage, leaving rolling blackouts behind

farming with desal water is insane. even with abundant power.

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)

andbbergeron Subway Builder: A realistic subway simulation game

this is just worse NIMBY rails

andbbergeron Ultrasonic Chef's Knife

if you have a nice knife and cut by dragging the knife towards you with tip in contact with the board instead of cutting directly down, food will not stick

andbbergeron Daniel Kleppner, Physicist Who Brought Atomic Clock Precision to GPS, Has Died

JILA is the golden child of the physics dept for reasons no one quite knows. Better facilities, higher stipends, separate events programming, same department!

andbbergeron Daniel Kleppner, Physicist Who Brought Atomic Clock Precision to GPS, Has Died

"The first scientists to succeed, in 1995, were Eric Cornell, Wolfgang Ketterle and Carl Wieman at JILA (formerly known as the Joint Institute for Laboratory Astrophysics), a research institute in Colorado." incredible underhanded dig from the NYT (against the rest of the Boulder physics dept)
