   Every time the discussion of time crystal comes up, a simple analogy can explain what it is. Regular crystal has repeatable structure in space, i.e. its lattice is the same shape over and over again across in space. Time crystal is the kind

   Yes. The GPU only runs machine code. That makes sense. GLSL is compiled by the OpenGL driver. The question becomes is WGSL sitting on top of OpenGL driver and thus requires the OpenGL drivers to support it or with a transpiling to GLSL,

   What's the difference between WGSL and GLSL? Is WGSL a native language understood by the GPU? Or is it a purely Web-level construct and needs translation to GLSL before piped to the GPU?

   Yep, O(n^2) has the problem that no matter how fast you upgrade your hardware it would still lag. Another pet peeve of mine is Civ 6's loading time for a saved game is atrocious. I'm sure there's a O(n^2) loop in there somew

   I've briefly used Mercurial and found it to be slower than Git in large repos. Mercurial has the concept of changeset (similar to Perforce) where the changeset is actually stored, while Git's "changeset" is computed as

   Wifi routers have this notorious problem with the nvram. Sometimes some state in the nvram is corrupted and the routers would stop working. Turning off and on again won't work. A factory-reset to wipe everything out is the only way

   Computer graphics basically follows what math describes (x,y,z) or what is on the screen or blackboard. On the screen, x-axis is left and right; y-axis is up and down. When z-axis was introduced, it just came in and out of the screen. Th

   Wow. I still remember when Amazon started as an online bookstore selling books and people kind of laughed at the idea, and the time Amazon kept losing money and refused to post an earning and people got mad. Amazing long game.

    Because the short ratio is still over 100%. With the clearing house catching up on the settling trades over the weekend, the counterparty risk goes down, allowing the trading platforms to lift the trade restriction, and allowing hordes of

    I've gone through a similar process. The gist of it is that it takes about 6-7 years to recoup the investment, disregarding compound return and opportunity cost. You can think of it as buying a bond that pays back in 6-7 years and th
