I think there is a genuine difference in the respect/appreciation for the arts between the two countries. Americans seem far more proud of their ignorance of the arts and in their lack of respect for artists.

I wonder if it might also be related to Japan's stronger laws against slander/libel and lack of fair use. I've seen many cases of harassed Japanese creators being able to drag their abusers into court in ways that seem very alien here

It's probably because high quality 3d is just much more expensive to do. You can easily do all sorts of effects in the constrained environment of a 2d model that take a lot more skill to pull off in 3d.

Plus, ultimately, the anime aesthetic is a 2d thing. It's a lot harder to make a 3d model look good in a 2d art style, as a ton of anime over the years have shown.

Exactly, I was working on a little client for a self-hosted server app. Imgui is a rare mix of fast, lightweight, trivially cross-platform and stable, so I went with it and had the client easily compiling for Windows, Linux and browser, while being trivial to work with.

I have otherwise mostly given up on making GUI applications because I simply don't have time to pick up a bunch of UI toolkits for all the different platforms, pulling a massive dependency into my project and requiring constant maintenance to keep the program working.

New Glenn Update 8 months ago

Did I miss a privately funded, reusable heavy lift rocket coming out of old space in the past 20 years?

New Glenn Update 8 months ago

New Glenn is manufactured with a different philosophy, so Blue can't be Starship levels of cavalier with testing. It would cost way too much to do with their current approach.

The factory tours for the two show this difference. New Glenn production is a lot more classical aerospace in terms of a high tech cleanroom factory being built from the start, versus a rocket that started out being built in tents that is slowly guiding the factory design as the tolerances are sorted out.

I think Blue's philosophy is pretty similar to the old space giants, except for being willing to invest a ton of money into improvements and new technologies without waiting around for the government to give them a blank check first.

Maybe we'll find that the thing limiting aerospace progress wasn't even that old space was afraid to test, but rather that they were simply unwilling to progress on their own initiative.

Of course it's possible for poverty to be a moral failure, but I think the point is to not be so quick to pass judgement on people you barely know.

I think an aspect of a lot of those luckier kids is that they think being told they were lucky invalidates the hard work they feel they did, turning it into a nonsensical contest of comparing apples to oranges.

My siblings have a similar complaint when my Dad essentially implies that they were lucky in having the successes they have had. They do still somewhat understand what he means, but they dislike it because they think he's dismissing the hard work they put in. Of course, they don't see that he applies the same to those experiencing extreme poverty.

It's to have something better than just the bare minimum. I remember seeing similar reports about higher education in remote villages in India, with cellular networks and internet access allowing people to learn without being able to move to somewhere close to sufficiently qualified teachers.

The image on the article talks about making Josephson junctions with it, and the abstract talks about epitaxial superconductor-semiconductor devices.

It feels like the researchers were mainly interested in applicability to Josephson junctions, and the article mixed them up with semiconductor junctions.

They're booked out years in advance only in the sense that bookings are sorted out years before the payload is ready to fly. SpaceX has emphasized that they're capable of swapping out Starlink launches with a commercial payload if needed on short notice.

Their own internet megaconstellation, called Project Kuiper until earlier today when they renamed it to Project Leo.

It's actually the current biggest commercial launch customer, Starlink is internal to SpaceX, but Kuiper/Leo has bought many launches with ULA, SpaceX and Arianespace (and Blue Origin, of course).

He was brought in to fix Blue's culture and try to speed things up, since the former Honeywell guy was taking forever to do anything.

I think it can be safely argued that since the fixes between attempt 1 and 2 happened entirely under him and faster than we're used to seeing from BO, he may have played a role.

I think they meant fields of research. If you do anything in NLP, CV, inverse-problem solving or simulations, things have changed drastically.

Some directly, because LLMs and highly capable general purpose classifiers that might be enough for your use case are just out there, and some because of downstream effects, like GPU-compute being far more common, hardware optimized for tasks like matrix multiplication and mature well-maintained libraries with automatic differentiation capabilities. Plus the emergence of things that mix both classical ML and transformers, like training networks to approximate intermolecular potentials faster than the ab-initio calculation, allowing for accelerating molecular dynamics simulations.

Yeah, that's a very fair point. The persecution of Fauci and anyone associated with bringing the charges against Trump would've also been very predictable targets for pardons.

There's enough of a market for them to exist these days. The issue is that companies want to treat VR headsets as if they're in the same category as phones or even tablets, when really, they're closer to the same category as, say, racing rigs or other highly hobby-specific products.

I wonder if Samsung has secured promises of commitment. IIRC they required Google to commit to improving Android's support for tablets before committing to devices like the Z Fold.

You don't need fusion power to melt ice, to move regolith over habitats for shielding, or to melt rocks to extract and process metals. I have absolutely no idea where you get the notion that it meeds fusion power? Solar power or things like kilopower reactors are a great option for Mars, especially for bootstrapping.

Pretty much everyone is heading in the direction of orbital fuel depots and orbital refueling.We're getting pretty good at launching rockets and docking things in orbit. Prior to Starship, ULA was considering having Vulcan's upper stage have refueling capabilities, but their parent company, Boeing, saw it as a threat to their SLS money and tried to get the associated engineers fired. All HLS proposals involved some sort of refueling and reuse capability, and both accepted proposals involve orbital fuel depots.

The only reason NASA hadn't already been investigating the relevant technologies is that politicians threatened to outright cancel space science funding if NASA so much as mentioned depots (the word was actually censored in documents from NASA about HLS until the relevant senator finally retired).
