Most people are familiar with conventional cubical six-sided dice, but there are also polyhedral versions like the 20-sided dice used in ancient Rome and to play Dungeons and Dragons. Researchers have figured out how to design dice with even more exotic shapes, like a kitten, a dragon, or an armadillo. And they are "fair" dice: Experiments with 3D-printed versions produced

How much slower is random access, really?

by Sam Estep, 2025-06-23 You may know that, because your computer has different caches (L1, L2, L3...), and memory operations operate on cache lines of about 64 bytes each, you should write programs that exhibit locality to get maximum performance. L1 L1 L1 L1 L1 L1 L2 L2 L2 L2 L2 L2 L3 RAM (Disk not shown, of course.) But how well do you understand this idea? For instance, let's say you have an array of floating-point numbers, and an array of all the indices of the first array. You have a p
