@PierceLilholt Advanced economies benefit everyone. Industrialisation, invented in Britain and diffusing outwards, basically made the whole world rich.

How will The Moon colonization be perceived by populations that struggle with basic survival on Earth?

They're just throttling, as they've been understandably cautious at signing orders for so many billions in compute. It would be nerve-wracking to write those checks just starting at subscriber math. Token demand is driven by adoption — that'll be the slow part rather than usefulness — but it'll be hard for the vendors to keep up. Eventually the intelligence density per unit of RAM will make it easier.

@space_stations Those are the bad ideas — I left out: 0. Spacesuit welding of I-beams.

This is what i mean when I say we need to right-size our dreams. We can do MUCH more than we are currently doing. But engaging in currently unbuiltable science fiction is an absolute waste of time. Everything I do is buildable and affordable, today.

I lost to someone who believes you can launch this 250,000m3 cylinder with a single Starship. Maybe if it's one ship that launches 10,000 times. FFS.

@space_stations Obviously he'd be better off with a monolithic inflatable than XXL monolithic rigid, but that's not the answer either. What should I do with some better ideas, other than just publish them, btw? Who do you think might commercialise it if I threw the design over the wall to them?

@simonrowland Well anywhere from a little bit less to about three times as much. I think it's possible to do but I'm just see all kinds of problems from the prospect of packing it in a way that doesn't damage it and actually be making it in a way that it holds up with no weak spots

@space_stations Honestly the well-known designs are not optimal. 1. Prefab metal cans with shuttle docking rings 2. Prefab semi-inflatables with shuttle docking rings 3. Self-assembling with magnets (sorry) 4. Panels assembled with lag bolts (better than welding) I have 3 new ones to write up.

@space_stations He also needs a wiring harness including power distribution, solar, heatpipes, regular plumbing, appliances, chairs, etc. If the 'stuff' inside weighs more than your structural design, you're doing quite well. I also don't know what he's doing for cte-matched windows.

@simonrowland It is like carbon fiber Starship. We know how to do it, but it's extremely hard, slow and expensive, which made the difference between something that looked good on paper and something that works.

@signulll I've already switched to just using a MD editor basically.

lol what is the underlying value of suites of software like this if they’re augmented by ai actually creating / editing / understanding the content? go see my post on office 365 which got me some hate dm’s. the underlying canvas for almost everything augmented by ai is going to ~zero primarily because they’re being attacked by dual forces. it’s this (claude) from the top, & infinite competitors from the bottom (cuz ai makes creating niche competitors as easy as apple pie). you have to be short almost every legacy productivity suite at this point.

Fun fact there are people seriously working on X-ray communication for hypersonics (missiles) and reentering vehicles in comm blackout due to the plasma sheath. X-ray passes right through it. Still a very sci fi concept at the moment.

@space_stations All the 'astronauts welding in spacesuits' stuff is a good start, but the best ways to make space habitats are going to be molten foam extrusion, CTE-matched Ni-Fe rebar with molten basalt using surface tension — continuous process stuff like that.

@space_stations No, but over 1M sq feet with < 20 launches, all but one being docking flights for commodities. I have to make a more detailed model but have been optimising the bejesus out of it.

@astrogrant It's all Chinese research, probably for hypersonic re-entry vehicles to threaten to kill westerners with, but happy that it's published.

@astrogrant Starlink requires a hole in the plasma ball you're in — that's super cool. I was trying to figure out how to get the data out of a disposable plasma magnet test article.

@_ZachFoster Are you just admitting that Hezbollah is simply an extension of Iran then?

@JeffGreason @S2SmeX All Long-EZs are cool (their fuel economy partly inspired me to do the PPL training), but that is definitely a cool one in particular.

On the dark side of the moon, a radio telescope could be suspended over a 5km diameter crater. it'd bypass the ionosphere and be shielded from Earth's electromagnetic noise, achieving substantially greater sensitivity. Real Engineering (@TheBrianMcManus): youtu.be/qdJ_gJ_kPEI

Introducing gyaradax 🐉: A JAX solver for local flux-tube gyrokinetics with custom CUDA kernels for acceleration. This entire code was vibecoded by @ggalletti_ and me in a month. Validated against GKW (CPU-only Fortran code) with 10x speedups. Details and code in the replies.
