I don't think a simulation needs to simulate anything real. Eg. if I have a program that runs Conway's game of life, that would be also be a simulation, but there's nothing "real" …

Afaik what makes fusion hard is maintaining the conditions that allow fusion to occur. Because of this, it’s quite safe - if anything goes wrong, it’ll just stop working.

Probably, but the amount would be tiny. ITER is trying to generate 500 megawatt from a half-gram of hydrogen.

This animation was super smooth on even the slowest iPad. The point of it is: they were going to do a skeuomorphic animation, and they put the effort in to do it right. It's a leve…

The page turn animation was truly excellent. I have seen a few other apps/sites try to copy it, some of them did it pretty well. But one detail I’ve never seen anyone else do: the …

It’s a question about ethics, I think it’s implied that legal consequences are not part of the consideration. But even when including possible jail time in your consideration: if y…

I don't think #1 matters, because it runs again once it's in a valid state again. Your test will fail while in an invalid state, but that's to be expected. As the author explained …

This tool doesn't run all the tests, only the ones affected by the code changes since the last run. It figures out which tests to run by initially running all tests, and storing th…

I folded his hydrangea design recently, following a video tutorial[1]. It is amazing. The finished model is a beautiful fractal flower. The folding steps aren’t terribly hard to do…

But the bullet will still hit the plane following you at roughly 1700mph (you could say, the plane will crash into the bullet at that speed, but it‘s the same result), because it‘s…

Do base your believe that Factorio is under-optimised on anything specific? The Factorio devs regularly put out blog posts on the optimisations they have done, like [1][2][3] (and …

Factorio's visuals support that take. I feel bad when the trees next to my coal power plant go brown and then die, and the initially beautiful blue lake next to the spawn point tur…

Touring completeness is about accurately simulating any Turing machine. Not approximately simulating one (what would that even mean?), or simulating just some of them. When we say …

There are efficient ways to compute x^n. Eg. you want to compute x^8. Instead of multiplying x eight times by itself, you can do ((x^2)^2)^2, which is just three multiplications. T…

The plan seems to be to have the gyrotron that generates the drilling beam on the surface, so the electronics don't have to withstand any heat at all. The "only" need to manage to …

The author does not state that people "disagreeing" with crypto are toxic, just that a subset of anti-crypto people are toxic. (Same applies to some pro-crypto people).

If you get past the fancy custom scrolling part of their website, it also mentions flax and switchgrass as other plant species that could be used in "climate solutions".
