@caveofjohn They think the world should be a shithole where everyone has $10 in the bank and lives off government assistance in rent controlled apartments.

@caveofjohn @DavidCarrollIr1 The ultra wealthy live by borrowing enormous amounts with their stock as collateral, regardless of it just being a theoretical sum of quantity * last-traded-price.
Why banks and other lines of credit do this is beyond my understanding.

Physics PSA:
I’ve just realized that most people think that because radiative cooling isn’t efficient on earth it isn’t efficient in space.
Radiative cooling is ~10x more efficient in space because there is no warm air to radiate heat TO the radiator.


ApoStructura@ApoStructura
Radiative cooling is pretty efficient, actually.SpaceX has been doing that for years on Starlink. The radiator is even going to be tiny compared to the solar arrays!
English

Oh my, my dunk of JerryRigs is going viral. Well, let's use this as a teaching moment.
First, realize when people say "data centers in space" they aren't talking about lofting up giant Costco sized buildings.
SpaceX and Starcloud are proposing satellites that each have the compute capacity of about one AI rack, or what the guy is pushing in the picture below.
These individual sats won't be connected together in space to run large training jobs, they'll only be used for inference - answering people's questions, running agentic tasks, etc.
So each satellite has relatively tractable power and cooling requirements. There will be a couple of largish solar panels attached to give it 24x7 cheap power (remember that you get like 5x more solar energy per panel in space than on Earth). And a smaller radiator that will radiate away waste heat into the vastness of space.
Both the power and cooling technologies are simple, well tested and cost nothing to operate, unlike power and cooling on earth.
In particular, cooling on earth requires extra power to run powerful water pumps to move fluid all over the place and then to dump the heat into a relatively hot atmosphere.
Yes, space based cooling can only reject heat via radiative cooling, but it is doing it in the vacuum of space at -454 °F (-270 °C, 3 K) versus about 77 °F (25 °C, 298 K) on Earth, so that helps a lot. Point being that cooling in space has only a single upfront cost of building a passive radiator.
But what about the overall cost, you ask? Well, think about all the things you don't need to build now. That rack the guy is pushing around weighs 1,400 pounds mostly because of all the metal required to support everything against Earth's gravity. Things can be built far more flimsy in space since they are in zero gravity.
Also that rack has a bunch of power electronics and fans, neither of which are needed in space. Indeed, that entire building those racks sit in doesn't need to be built. All that fiber cabling isn't needed (lasers in space take the place, no need for cables). Giant utility transformers and a small army of step down transformers and battery packs don't need to be built. The land doesn't need to be bought. The permits don't need to be acquired. The supposedly huge amount of water used doesn't need to be provisioned (it's a tiny amount, but the detractors love to bring it up).
There are in fact giant cost savings going into space.
What about launch costs? That is small as well. Starship is fully reusable. The majority of launch costs are natural gas and liquified oxygen extracted from the air. That's it. Cheap access to space, really cheap I mean, is a huge unlock.
I was initially shaking my head when I first heard about Elon's "crazy" idea of space based compute, but the more you look into it, it is far less crazy and more doable and practical. At least for SpaceX.

@benconrad34 @SuddenLncident "stunt" 🙄. It's perfectly legal where I live, up to 30 km/h
English

@SuddenLncident If you cared about your life, it wouldn't be possible for this to happen. I don't understand how some of them risk it all just for a dumb stunt.

@bailout00 @DJSnM Eh? Most landings are hand flown to the ground. How do you expect the pilots to be proficient?

@smith_johnxxxx @SecessionWA Also it's the libs that have a hardon for selling everything for short term gain.

@SecessionWA We’re not defended now. Albanese has a few boats, some jets in Katherine, some tanks in NT, and some second hand subs that Marles is getting from America. Plus Albanese has let China buy everything here anyway. It’s a joke.

@smith_johnxxxx @SecessionWA Did you forget that it was your fuckwit Scomo that got us into this used sub mess?

@rogmcbrider @SecessionWA Howard started the 4 pronged attack on housing affordability, you fucking moron.
Inflation isn't even at 1/3 of historic levels. 🤷
That's not to say that Labor hasn't been a willing participant, but to blame just them only shows how clueless you are.
English

@SecessionWA Not the Labour government there fucking it up for all of us spend spend spend , $$$ inflation up @ record levels, house prices through the roof it’s all going to end very badly, just remember the GFC in 2008 same shit is happening wake up ! 🔖🤓🤓

@SecessionWA You can't explain yourself without an LLM... You couldn't secede your way out of a paper bag.

@BenjaminDEKR There was a heap of testing at all scales though, so the slide rules aren't as much of a hindrance as you might think (also there was some computer design). Empirical relationships for your structure work well and still form most of the analysis on modern airliners.

@SamaHoole There's clearly something else wrong if 65% of the meat eaters are also protein deficient. It's probably mostly poverty.
English

India is the great natural experiment in plant-based eating, and almost nobody wants to run the numbers on it.
It is the most vegetarian large country on earth, hundreds of millions of people, many vegetarian from birth. Grain at the base, pulses, vegetables, all cooked in vegetable oil: the government Eat Well plate, run as a national experiment for thousands of years.
The result. Around a third of its children are stunted, the largest share of the world's stunted children of any nation. The Indian Dietetic Association reports 84% of the country's vegetarians are protein deficient, against 65% of its meat eaters. And the nation that eats the least meat is the diabetes capital of the world, with over 100 million diabetics.
Before anyone blames poverty, a Journal of Nutrition study found a vegetarian mother predicted stunting across every wealth bracket, rich families included. The diet was carrying its own weight.
Bioavailable iron, zinc, B12 and complete protein build a child's skeleton. Strip them out and it comes out smaller. The animal fat, meanwhile, got swapped for refined grain, sugar and seed oil. India is now the world's biggest vegetable oil importer, per-person intake tripled since 2001.
The diet sold to the West as optimal human nutrition has been run here, at the scale of a billion people, for longer than the West has existed. It did not produce optimal humans. It produced the largest population of stunted, diabetic, protein-starved people on earth.

@DesonOllie $12.50 at rôll’d basically country wide. You go adding things like wagyu and the price is obviously going to jump

@karldlindgren @JohnWil40034141 @HalfwayPost You're an idiot if you haven't noticed that republicans haven't been republicaning for a long time. Small government and fiscal responsibility? NOPE 🤣

This is stupid. If you’re eating solid lean meat it’s basically 100g of protein per 100g. Chicken breast is very lean so there’s really no fat there. Not sure what kind of meat samples you are talking about but meat is protein…not fat…not carbs…so what else would be there in 100 g becides protein
English

Pensaba que la pechuga de pollo era la reina absoluta de la proteína.
La comía casi todos los días.
Hasta que me pregunté:
¿Realmente es el alimento con más proteína que podemos encontrar?
Ranking de alimentos ricos en proteína (por cada 100 g):
10. Lomo de cerdo → 21 g
9. Salmón → 22 g
8. Carne magra de res → 22 g
7. Atún fresco → 23 g
6. Pechuga de pavo → 24 g
5. Pechuga de pollo → 24 g
4. Queso parmesano → 35 g
3. Cacahuates (maní) → 26 g
2. Atún en conserva → 29 g
Y el #1 casi nadie lo consume con frecuencia...

@Scribbles646 @CryptoCyberia Wrong. It's an ITAR restriction and cheap Chinese micro bolometers do 25 fps just fine.
The shortwave infrared that a normal digital camera detects is an order of magnitude different to long wave, and useless for thermal imaging.
English

@CryptoCyberia Higher FPS would require better optics and a larger photosensor, lowering the fps is the digital equivalent of a slower shutter speed, more photons to build each individual image with, both consumer and professional digital cameras can detect infrared if you remove the IR filter.

@StephanSturges The Titan analysis was a static analysis and nothing to do with implosion.

@Will4Planet You're not seeing anything that you weren't seeing at 3m, you're just making AI assume that previous patterns represent what you're seeing now. It's not real data. What a fucking joke. This isn't far removed from smashing the sharpness setting on a tv.
English

Today we announced Planet SuperRes, a breakthrough tech that uses AI to uplevel our PlanetScope near-daily imagery from 3 m to a much sharper 2 m resolution. 🛰️
Really cool things done by our team to make this happen. The model was trained on over 120,000 SkySat and PlanetScope satellite image pairs. We can now see things we couldn’t before -- making small-scale objects and textures visible for analysis.
Better data helps us make better decisions. planet.com/pulse/planet-s…
