Cool success story of Cython

Real Python (@realpython)
A multi-core Python HTTP server (much) faster than Go (spoiler: Cython)

This is handy. It makes perfect sense that Python -- with a little help -- can be compiled down to super-fast code. Hopefully, the Cython world will continue to evolve toward using native Python type hints.

When Cython uses fully-native type hints, it becomes a super-convenient and transparent performance booster.

Without full-native type hints it becomes a place where bugs are injected as part of trying to improve performance.

Python Dependency Management

Freezing Python’s Dependency Hell in 2018

Excellent advice.

Excepot for the "Don't use Anaconda." Yes. It's a big download. Odds are good you'll need most of it. So. Just do it now.

The (miniconda + environment.yml) as an entry point is really good. The "rely on people to actually know and consistently use their best practices" doesn't seem like a problem, it seems like a consequence of an evolving software ecosystem.

Why is Python so slow?

This is brilliant. 

Why is Python so slow? by Anthony Shaw

It covers three aspects of the implementation in a respectable level of detail. Helpful information. Bookmark it to help stop pointless bickering with people who don't understand the value of getting something to run right now vs. getting something that will eventually run and be fast.
