Apparently a new paper is supposed to come out from the original authors about the production method [0]. So it really is unclear whether everybody generates the same material.

It's a shame that these papers were published before they were polished by the authors.

No it's about the renaming of Twitter.

You can check out Tech Ingredients video [0] on the same topic, which will give an answer to your question. It is: Yes, it is better than regular white paint

Nice method, what infill do you need for that to work? 100% or is less possible?

There's some more info on steam [0] about the release.

TL/DR: 30 $, Legend mode for sure, Arena and Classic mode maybe or a few weeks after. More updates (graphics, Mac & Linux support) a bit later. Adventure mode will follow.

The big issue with intersections of convex objects is that there might be infinitely many intersection points (two cubes lying on top of each other). This creates a multitude of numerical issues. I worked on this topic extensively for a DEM software where you need to calculate a lot of these interactions with extremely high precision (overlaps between objects are usually < 1% of the bounding radius) and since it's not computer graphics but engineering you really need stability and performance. That was a real tough challenge involving lots of identifying limiting scenarios during large simulations but it works quite nicely now [0].

While I do not follow these discussions I'd argue that the advent of drones plays a major role in that. Additionally as long as our space tec remains as primitives we are quite boring as a civilisation

TechIngredients on YT [0] also has a ongoing series about how to set up your own jet engine.

Check out the video by Scott Manley, he explains quite a bit: https://www.youtube.com/watch?v=0FWO1Pvbhq4

Fair enough, I misinterpreted GPs post. He and you are obviously correct.

There's no drifting there. What you are seeing is gravitational lensing. The light of (most likely a galaxy) is bent around another galaxy or star which distorts its appearance. Also this means it can potentially show up multiple times on the image (e.g. opposite side w.r.t. the lensing object)

Well if you look at todays economy what do companies require? Fast and faster is the way. The schools are here to produce fast workers. There's hardly a day a year where you can sit down and work on a project without time pressure.

The topic reminded me of some fun wave tank videos like this one: https://www.youtube.com/watch?v=4384y5ZRRIs

Well from experience the interface is conferences and papers. On conferences you get to know the latest stuff that is going on and the implementation details can be found in papers.

What needs to be said though is that reimplementing something from a paper is near impossible. I had to do that a couple of times and I was only fully successful if the paper was accompanied by some open source code as there always are tiny little edge cases or initialization details that won't be covered in the paper.

Of course my statement wasn't meant to be absolute. I come from an engineering background. I am not surprised that in a medical setting the situation is somewhat different, after all I guess the stakes there are higher. If your CFD code does not perform well, who cares. If your analysis of some medication is crap, chances somebody cares is going to be much higher.

Also from experience, it helps if universities have closer ties to industry. As an industrial player you can't work with software that does not deliver reproducible results.

Well I think the best way would be for RSEs to maintain a project and PhDs should then contribute to that project via pull requests. RSEs can then point towards proper coding styles, test development, etc.

That would ensure that the contributions of the PhDs does not get lost and they learn how to properly contribute to a project.

There is simply no incentive for science to do proper software engineering. It does not directly produce papers or money, so nobody does it. I've seen it several times in my own career in several countries.

PhDs having their own version of the code, incompatible with the one of the Postdoc sitting opposite of them. Each slaving away at their niche project but nobody there to bring it all together. This particular university had really great code and they thought they could sell it. But they did not even use git and when I gave a presentation there about it, I was met with absolute rejection. They don't have an idea on how much effort it takes to maintain a commercial code, unit tests, customer support etc.

I'm now working at a company that produces simulation software spun out from university. Fantastic job and we do all of those things mentioned above. But obviously my paper output has been near zero even though we sometimes do cutting edge research.

I wish I had a solution to the problem as so much grant money is wasted that produces a paper or two and the corresponding software for that just goes to digital nirvana, it's a real shame.

Most likely they imaged Sagitarius A* the black hole at the center of our milky way and will present this image.

Source? Several raptors have been fired for long duration and even multiple times. If the chambers would melt that should not be possible.

Of course RUDs of engines happened but they were the exception and not the norm.

Indeed. Another aspect that could cause quite a disruption is cheaper access to space. With Starship coming to life, launching heavy and large stuff for very little money should enable previously "impossible" space telescopes (be they electromagnetic, neutrino or gravitational wave based).

Musks goal is to Marke humanity multiplanetary. If he just wanted to milk the space cow Starship would not be necessary.

Thanks for that, this looks indeed like a fantastic educational game (previous discussion [0]). Seems there is a similar game to building "computers" [1] as well.

Merry Christmas! Frohe Weihnachten from Austria!

Its not only the mixture, its also the pressure at which those gases are coming into your bloodstream. If you breathe compressed air you get the bends. As freediver you don't have much in terms of volume of compressed air, same for animals of course.

Scott Manley did a great video on the probe and its approach: https://www.youtube.com/watch?v=1Sj9cjwFhQY

While I don't have any hard evidence to back up my claims, I would tend say no. Reason being is that we are mammals and some mammals live in the ocean like seals. Their bodies have the same reaction to diving than ours [0] and it certainly does them no harm. Sure they are more efficient and better adapted, but the underlying physiological principles are the same.

Considering this article is actually very good, I am sure they have heard of him. While he is absolutely impressive and one of my favourite divers, the pure numbers speak for Alexey.

While a blackout sounds horrific and certainly requires an immediate response, it's not necessarily bad. Afaik there are no studies about it, but I would guess a blackout does not result in any long lasting injuries. In the end a blackout is the bodies response to keep you alive just a little longer by focusing on the absolute minimum it takes to do so.

The safety protocols have also evolved over times. Nicks death for example has triggered a rewrite of the rules that would require a medical examination after a blackout or if you cough up blood. This examination can result in a ban from further competing for the next days for example.

Of course it's not a safe sport, it's an extreme sport in an extreme environment. But lots has been learned in the past decades, as it is still a rather "new" sport and if exercised correctly it is rather safe. Also the article just talks about a competition. Most freediving happens either in training or when people do it recreationally. While accidents happen there as well, these are mostly about the lack of safety divers, that's why the first rule of freediving is, never dive alone.

Finally, on your last paragraph, freediving does change your day to day life, at least from my experience. I just do it recreationally, so I'm far from these depths and times Alexey and the others achieve, but the mental control you learn can be applied in many situations.

I just skimmed the video so my TL;DR might not capture everything he said.

Basically, he advocates a new license that he wants to develop that basically improves remuneration for open source developers. Use case: A "Post Open" software is used by a company, then this company has to pay a certain percentage (1 to 10%) of their revenue to the "Post Open" software. If it is using multiple "Post Open" packages this percentage is divided among them (according to usage).

Software in this scheme will be allowed to be modified, redistributed etc. and it will also contain a public API that defines the boundaries of the program (so it's not about linking anymore).

I hope that captures the key points.
