Totally agree with you on ‘putting stuff away’. Much of the mental effort is trying to organize stuff so it takes space efficiently, and be easy to find it when I need it. If a robot put it away, I don’t really care where. I can just ask

Global cellular operator revenue is approx $1T. They have put their toe in the water with direct-to-cellular support for starlink, and have bought spectrum to improve this. I'm sure they basically want to offer cellular to everyone in

Once in a while I get inspired by a post on HN, but I know I don't have the energy to follow it through. Here's my idea for anyone who thinks they can do something with it: Imagine you are holding in your hand a small glassy sphe

This seems like a good opportunity to share my recent photos from a bookstore in Tokyo… just a crazy number of computer books. Mostly in Japanese language. https://imgur.com/a/Kygj5IM Many of those are not programming

Surely, the question is: how big do the radiators have to be? gemini says that the NVIDIA DGX H100 is 130kg and takes 11kW. It says space-based radiators in the 100kW range are approx 15kg per kW. And space-based solar panels are approx 1kg

It will be used for spatial content, for viewing in Apple Vision Pro headset. In fact you can already turn any photo into spatial content. I’m not sure if it’s using this algorithm or something else. It’s nice to view holiday photos with s

> Access old ideas? Yes. With new perspectives? I wonder if we can mine patent databases for old ideas that never worked out in the past, but now are more useful. Perhaps due to modern machining or newer materials or just new application

Trex makes composite decking planks from recycled shopping bags. Seems like a perfect use for the material. Its durable. It doesn’t have to be sterile or pure. Apparently 100,000 bags will go into a typical deck. https://nextrex

I don't get why everyone keeps talking about the planets aligning. All the planets are pretty much in the same plane. So if you are on one of the planets, all of the others will always be in a line. edit: to those downvoting me, can

Methane derived from co2 and h2o with solar energy is not a fossil fuel. Methane from the ground is a fossil fuel. Casey is going after industry that has a lot of inertia behind methane with a non fossil derived methane.

I see they are going for the high-end market. Seems the right path to me, for now, since they can charge high prices for foie gras without the guilt. We eat beef, chicken, pork, and lamb, because they taste good, and are cheap to make beca

The smaller nuclear reactors used on submarines and aircraft carriers would be of the appropriate size, but they generate electricity using steam turbines. I don't think that would be workable in space. You'd need massive radiat

If a single mission to mars cost $100b, then I would agree with the article that it would probably not be worth it. SpaceX is focused on reducing the cost, and no matter what you think of Elon, you have to agree that spacex focus on reusabi

They used these thicker bags 20+ years ago, then went to the thin ones. Now we all figured out how useless those thin ones are. And we’re back to the thick ones. It’s quite shocking visiting a place with no bag restrictions like Florida or
