The most interesting part for me is not the top-end 192 core size, but the small/medium sizes.

Looks like m9g.large is about 9% more expensive than m8g.large on-demand, at least in Vantage’s current data.

If the “up to 25% compute improvement” holds for real web/database workloads, that is a pretty reasonable perf/$ trade. The usual caveat is that small SaaS apps are often bottlenecked on DB, storage, or network long before raw CPU.

Nice example of an algorithm that is simple enough to explain in a few lines, but still changes how you think about floating point errors.

Nice visualization. Putting the cells directly on the sphere makes the nearest-neighbor idea much easier to understand.

On a flat map I always have to ask myself how much of what I’m seeing is geometry and how much is projection distortion
