    Don't think there was ever a Top Gun for Virtual Boy.

    Pretty neat and a very nice walkthrough of the code. For localization you might want numbered holes which makes it way more complicated. You can detect if the backing buffer is too…

    Well actually, air molecules (N2, O2) are indistinguishable. This means that they are fundamentally interchangeable with each other and it’s not well defined what ”same” molecules …

    Second this recommendation! It’s a super fun game to learn. It looks impossible to start out but then your brain adapts. It’s like seeing through the matrix.

    The result is only significant to 3.39 sigma. Pretty good chance this is just a random fluctuation that will go away if you look at more galaxies.

    Also first click is never a mine (if there's one where you click it's moved to the top left corner).

    In my high school physics class we measured the pitch between the tracks of a CD using the same principle. You just need a light source with a known wavelength, like a laser. It wa…

    Yes I’m thinking in terms of different frames of reference. Imagine that you’re a tiny ant that lives on the large circle. When you push the small circle around the large circle yo…

    Making code simple is not easy. In your analogy I think the listener should be the junior programmer. Music by Beethoven can be appreciated by many more than just the people who ca…

    Interesting case! You can see it is R/r local revolutions of the small circle. Then you need to add one global revolution from going around the large circle. So R/r + 1. This is of…

    Instead of energy, it should say amplitude(and phase since it’s an inherently complex thing).

    You can use it solve sudokus as well [0]. I find the parallel quite enlightening. [0] https://norvig.com/sudoku.html

    Oskar Stålberg has famously used WFC in Bad North and Townscaper. Here's a nice presentation from him explaining it: https://www.youtube.com/watch?v=0bcZb-SsnrA

    Europe is not uniform in this regard. For example in Sweden almost all houses are built out of wood.

    The OTCA metapixel has 2048x2048 cells and a period of 35328. That's a total of 18.5 GB. And that's not counting the different states depending on neighbors and on-off-transitionin…

    Very smooth. Wonder if there are any optimizations like Hashlife going on? There’s a lot of spatial redundancy to exploit. https://en.wikipedia.org/wiki/Hashlife

    Comment #33771371

    Yes, and in particular the compiler can assume that you stay within the defined behavior. That's what's enabling the optimization in removing the i < 0 check.

    There’s no reason to expect the result of integer overflow to be negative, or any particular value at all. It is undefined. So after checking that x > o there is no way for i (a pr…

    You’re gonna get the same result each time you compile. But if you change _anything_ the results can be completely different. So, I can agree that it’s not a very useful predictabi…

    Comment #33507904

    The situation in C++ is similar. With a particular compiler and with a specific set of compilation flags you can sometimes get predictable behavior even if it's undefined (and some…

    Conway's Game of Life does consider diagonals. Since they start and finish by talking about GoL I think they've made a mistake.
