Michael #1: Dokku
- An open source PAAS alternative to Heroku.
- Dokku helps you build and manage the lifecycle of applications from building to scaling.
- Powered by Docker, you can install Dokku on any hardware.
- Once it's set up on a host, you can push Heroku-compatible applications to it via Git.
- Rich plug in architecture.
Brian #2: Summary of Major Changes Between Python Versions
- Nicholas Hairs
- Changes between versions & Tools & utilities to help with switching
- Hopefully you’re already at least at 3.8, but come on, 3.11 & 3.12 are so fun!
- Useful things
- pyupgrade can automatically upgrade code base
- (However, I frequently just upgrade and run tests and let my old code be as-is until it bugs me. - Brian)
- black checks pyproject.toml requires-python setting and uses version specific rules.
- Versions (way more highlights listed in the article)
- 3.8
- Assignment expressions := walrus
- f"{variable=}" now works
- 3.9
- Typing has built in generics like dict[], so no more from typing import Dict
- Dict union operator
- Strings can removeprefix and removesuffix
- 3.10
- Structural pattern matching match/case
- Typing: Union using pipe |
- Dataclasses support slots=True and kw_only=True
- 3.11
- tomllib included as a standard TOMP parser
- Exception groups
- Exception Notes add_note()
- Typing: A Self type
- Star unpacking expressions allowed in for statements: for x in *a, *b:
- 3.12
- f-strings can re-use quotes
- Typing: better type parameter syntax
- Typing: @override decorator ensures a method being overridden by a child class actually exists.
Michael #3: How to check Internet Speed via Terminal? speedtest-cli
- Command line interface for testing internet bandwidth using speedtest.net
- Just pipx install speedtest-cli
- Has a Python API too

- Maybe tag it as Not By AI
Extras
Brian:
- If upgrading to pytest 8, be aware that running individual tests with parametrization will result in a reverse order.
- It shouldn’t matter. You shouldn’t be depending on test order.
- But it was surprising to me.
- Issue has been logged
