When I read the title, I immediately though, I think this is going to be about Brussel sprouts etc. as I just saw a video [0] that mentions the same lineage. The video is part of the series about the evolution of the flagellum, which is really well made.

Stated clearly (0) has recently started a fantastic series about evolution that aims to explain bacterial flagella. It starts from basic principles and aims to answer questions like yours in evolutionary biology.

Maybe you should train an LLM to judge the content /s

More seriously though, I think some sort of curation is unavoidable with such topics. If you get inspired by stack overflow where you have some similar mechanics at work, then I'd say that is not too bad. But of course you risk some people being angry about why their amazing vibe coded app is not being shown. Although the more I think of it, this might be a good thing.

Edit: One more thought just came to my mind. A slight modification to the curation rule, you let everything through, just like now. However, the posts are reviewed and those with enough postive review votes get marked in some shape or form, which allows them to be filtered and/or promoted on the show page.

Additionally i would argue that in every such programm there will be people that abuse the system. Just because gp knows one such person, does not mean that everybody will be doing that.

The article also mentions that overall the program had a positive impact.

Not necessarily, the measurement train my company develops can go up to 100 km/h and measure certain rail features every 5mm at that speed.

Apollo 1 burned quite well unfortunately. But IMHO it makes no sense to compare those things anyways.

That's also what he writes in the article, I.e. LLMs are large language models, so the approach is generally flawed. A sentiment I agree with.

Correct. Usually you need to perform a so called surface protocol after surfacing to show you are still conscious enough. This can be e.g. the removal of your mask, an OK sign and saying "I'm OK". Only if you do that within 15 seconds after surfacing your performance will be valid.

And regarding easy to blackout. Yes and no, I personally avoided it for over 12 years, but then again, I'm no world class athlete and only an enthusiastic hobbyist.

You cant avoid co2 build-up, you can only slow it down, main factor here is relaxation. Particularly your brain needs loads of o2, so if you can keep that calm it helps a lot. Obviously a slow metabolism helps as well, so before big static performances fasting is common.

And regarding co2 tolerance, it is a training effect. With training you can withstand much higher levels of co2 without resulting in panic

To answer your questions:

- A coach / safety will give a signal to the athlete, e.g. pinching of the arm and the athlete will react to it by e.g. lifting a finger.

- Training. You get to know your body and limits very well when training freediving for a longer time. That does not mean that you always avoid blackouts, particularly in competitions they happen but that's what safeties are for. In the end, a free diving competition is one of the safest places to explore your limits.

Why not? Its a big difference whether you go ski jumping in leggings or in a wingsuit. Obviously the difference in reality is less, but the principle stands

Not sure your last statement is necessarily correct, just think of the massive doping in the former soviet union. The prestige gained by countries due to e.g. the Olympics regularly causes people to use illicit means.

I thought the same but after watching the Netflix TdF documentary I would not agree to your statement anymore. Team strategy plays a huge role as e.g. driving in the slipstream saves up to 40% of your energy expenditure.

There is a sport called finswimming which has underwater speed disciplines (apnea or with bottles). But as the name implies it comes with the use of fins.

Nice implementation. I found it very intuitive to find the necessary features like marking a mine or tapping on a number that has all its mines marked to reveal the safe squares.

But it might still be good to put a short description somewhere for people not as familiar with the game.

Ah thanks I missed that. Then it seems there is nearly no damping used.

Would be interesting to know what integrator they use. Verlet schemes can be implemented with very little effort and they don't suffer from this issue (see e.g. the leap frog method). But in general you would nearly always add some sort of damping mechanism, particularly for CG applications.

Not op, just an observation, when you are underwater e.g. diving these things are really loud. Of course jet skis etc are even worse but the latter is not permitted were I go diving. Maybe that's part of the resentment.

I also tend to use my freediving experience for the opposite, when I'm highly stressed I tend to do one or two short (full exhale) breath holds to calm down. This works amazingly quickly and let's me refocus. Note, this will probably not work for untrained individuals.

That is still considered hyperventilation as a freediver, even though you might not feel any symptoms. The suggestions you gave in your previous post are dangerous and should not be done. Please take a proper course to learn about free diving physiology and safety. Otherwise this sport can get dangerous very quickly.
