The light curve is not smooth, there is a clear spectrum caused by absorption lines. You find the pattern in the lines that you know to be hydrogen, and measure how much redder it is than it would be without redshift.

by Tuna-Fish 6d ago
Yes, and we are already accounting for it. The objects as seen by us are actually very deep in infrared, when you correct for the redshift to match the key absorbtion lines of hydrogen, they still remain very red.

In SSME, most of the LOX never goes through a preburner. The SSME uses the same kind of fuel-rich combustion chambers for both preburners. This presents a problem for the oxidizer side because any leaking along the shaft between ox pump and

Eh. A lot of materials get their strength from being worked, which 3d printing doesn't do at all.

I'm pretty sure that the heat exchanger is going to end up being one part they have to put back in. Pushing CO2 and H2O (both ices at prop temp) into the tanks just seems so ill-advised to me. The amounts of contamination are small, bu

Backprop has significant costs, if a local solution truly matches its performance, it will be dropped like a hot potato.

> You can do that with backprop too. Nothing says you can't inference on a set of weights at the same time as you produce an updated copy from them. Nothing but economics. Inference requires dramatically more memory, meaning it gets

I have clearly communicated the constraints of use on my site using robots.txt, which is the established standard for communicating things like these. You are expected to fetch it and figure it out. It is not necessary to build walls and lo

I think having a horizon is very useful for the immersion. If flight sims were less of a niche category, I think VR would be mainstream. VR just improves them that much. Sadly, the entire flight sim market is probably insufficient to sustai

Aren't those really easy to explain? EU opposes the Houthis because they are a horrifying slave state that distributes children as sex slaves to their troops. EU opposes Russia because it is a horrifying fascist dictatorship that has r

Rust allows much more aggressive optimization of the reference types than C++. If you have a &T, the compiler can assume that it will not change over the entire lifetime of the reference , and reorder things even past things that a C++

If nxm isn't saying that, I cannot imagine what the point of their comment was? Would you care to explain what you think it was? Why would anyone ever type that comment as a response to the comment above?

You seem to be confused about what organizations do what. ESA neither launches or builds rockets. They are an end-user, and they own the launch infrastructure in Kourou. Both these roles will exist long after Ariane is gone. Arianespace doe

Musk has benefited enormously from public contracts and policy, but all the questionable ones are in Tesla (and especially originally solarcity, but that got folded into Tesla). The government contracts that made SpaceX were all open bid, w

ESA is going to remain on the mission/payload side. ArianeSpace makes sense as a launch services provider handling everything that's not the rocket. ArianeGroup (the company that actually builds the rockets) will just become the F

That's fixed by having the CI server compile the code and run tests, and having it fail the merge and publicly shame the offender in slack when that happens. It's often said that you can't fix behavioral problems with technol

Yes and no. A single chip cannot have it's weights adjusted, once it's out, it is what it is. But also, the model weights are in a single mask rom layer, high up in the metal stack. They could manufacture the die specialized for a

Plenty of people wanted to do the work. Lot of European politicians were desperate to do the work. But it turns out that when a fascist has nukes, there's not much you can do to convince them to not be fascist.

We unfortunately have not found a way to turn our kleptokratic dictatorship neighbor into one. The greatest failure of the past 20 years was the belief that if we open up trade and grow rich together, rational self-interest will lead to lib

Many algorithms can be reasonably converted into matmul. Not many algorithms can be reasonably converted into very low precision matmul. And that's all that these things are going to do.

At this scale, moving from one pointer chase to multiple is almost certainly a huge loss, even if radix tree would save a lot of memory.

Designing a specific model into silicon buys you three orders of magnitude of speed and energy-efficiency. Flexible, software-defined solutions are used today because adaptability is key in an environment where people expect better models

At the basic job of showing a normal 24bpp photo on screen, the differences between the formats are marginal. jxl shines when you want to do anything even a little bit more complex. Support for lots more color formats, including fp ones. Su

Huh? Stennis Space Center is a propulsion research site, it's not usable for orbital launches. There are towns south of it.
