Teeny nit, the sun produces light well into the x-rays (mostly from the corona though). You're probably talking about sunlight making it through the atmosphere.

If you like the art you should try and play Cosmic Osmo! It was my favorite game to play on the Performa PowerPC macs my elementary school had. It’s a very short and silly game made with hypercard. The creators later made Myst using the sam

It’ll be guarded by a fine-grained mutex, so it won’t seg fault. They’re using a performant mutex based on webkit’s wtf::lock.

Fun to see an open source project I contribute to (numpy) used to commit some light fraud.

I find py-spy really useful in python, it would be neat if you integrated with that somehow.

I’m working on adding missing data support for strings as part of adding a UTF-8 variable-width string type to NumPy. Not a general solution but should help with a lot of use-cases. https://numpy.org/neps/nep-0055-strin

It’s a little easier to write idiomatic python bindings for a C/C++ library in Cython IMO, because you’re writing the bindings in a language that’s almost python.

I guess it’s mismatched expectations. IMO the primary use-case is making python wrappers for C/C++ code or converting prototype Python code into a fast C extension for production use by adding types or progressively converting code int

Cython 3 also uses python type annotaions to infer C types now too, so if you add python types you might see surprising cython speedups.

Maybe you'll find the paper I wrote describing unyt ( https://joss.theoj.org/papers/10.21105/joss.00809 ) useful? unyt doesn't have type annotations so if you need that then it's not a good fit.

You might find unyt useful: https://unyt.readthedocs.io Disclaimer: I am the primary unyt maintainer.

I have a watch with lume powered by phosphor-coated tritium vials. I’d better keep it safe from terrorists trying to build dirty bombs.

Glass is much more slippery than a plastic or leather case. I’ve cracked a caseless phone’s screen after it slipped off a slightly off-level table. I always use leather cases now and no longer have the problem of my phone randomly slipping

I think the idea is for cython to move away from generating CPython C API code to generating hpy code in the long run. From the point of view of cython users this won’t make much difference.

CANadian Oil Low Acid, it’s lower in erucic acid than other rapeseed cultivars. In the early 70s there were studies in rats that showed that erucic acid caused heart disease so canola was marketed as being healthier.

Yes, all locally smooth complex functions (e.g. whose real and imaginary parts satisfy the cauchy-riemann equations) are analytic, one of the main reasons complex analysis is way less of a pain than real analysis.
