Michael #1: “We must replace uwsgi by something else”

• uWSGI is now in maintenance mode: https://uwsgi-docs.readthedocs.io/en/latest/
  • The project is in maintenance mode (only bugfixes and updates for new languages apis). Do not expect quick answers on github issues and/or pull requests (sorry for that) A big thanks to all of the users and contributors since 2009.
• Reasonable options look like:
  • granian
  • uvicorn
  • hypercorn
  • gunicorn (potentially with uvicorn workers for async)

Brian #2: Let’s build and optimize a Rust extension for Python

• Itamar Turner-Trauring
• Example: algorithm for approximating the number of unique values in a list
• Comparison to non-approximation
  • non-approx is faster but uses way more memory
• Rust version
  • Use Maturin and PyO3
  • Pull in Rust dependencies (rand for random numbers)
• Optimization
  • link-time optimization
  • faster random
  • store hashes only
• Future optimizations
  • change algorithm maybe
  • pass numpy array instead of Python list (I’d like to see that spedup)
