hyuijkon AWS switch from gzip to zstd – about 30% reduction in compressed S3 storage

If the customers stored .gz/.zip/... files you could transparently transcompress them to .zstd and back (with an added test of course)

hyuijkon What is quantum field theory and why is it incomplete?

But who says the computer running the simulation must be exact?

We are using a lot of low precision computations in graphics, neural networks, ....

Pi also can't be calculated exactly to infinite precision, yet that doesn't stop us to compute circles and so on.

hyuijkon Three papers highlight results of record yield nuclear fusion shot

My understanding is that one big reason so much money was invested in this lab is because the research has direct applications to nuclear weapon design. It's a dual use lab so to speak. The process they are studying is very similar to what's happening in the core of a thermonuclear bomb.

> Today, research on inertial confinement fusion—the other leading approach—remains largely under the control of US national weapons labs. The military focus has had profound impacts on the development of inertial fusion energy.
