Michael #1: port-killer

A powerful cross-platform port management tool for developers.
Monitor ports, manage Kubernetes port forwards, integrate Cloudflare Tunnels, and kill processes with one click.
Features:
- 🔍 Auto-discovers all listening TCP ports
- ⚡ One-click process termination (graceful + force kill)
- 🔄 Auto-refresh with configurable interval
- 🔎 Search and filter by port number or process name
- ⭐ Favorites for quick access to important ports
- 👁️ Watched ports with notifications
- 📂 Smart categorization (Web Server, Database, Development, System)

Brian #2: How we made Python's packaging library 3x faster

Henry Schreiner
Some very cool graphs demonstrating some benchmark data.
And then details about how various speedups
- each being 2-37% faster
- the total adding up to about 3x speedup, or shaving 2/3 of the time.
These also include nice write-ups about why the speedups were chosen.
If you are trying to speed up part of your system, this would be good article to check out.

Michael #3: AI’s Impact on dev companies

Brian #4: CodSpeed

“CodSpeed integrates into dev and CI workflows to measure performance, detect regressions, and enable actionable optimizations.”
Noticed it while looking through the GitHub workflows for FastAPI
Free for small teams and open-source projects
Easy to integrate with Python by marking tests with @pytest.mark.benchmark
They’ve releases a GitHub action to incorporate benchmarking in CI workflows

Extras

Brian:

Part 2 of Lean TDD released this morning, “Lean TDD Practices”, which has 9 mini chapters.

Michael:

Our Docker build just broke because of the supply chain techniques from last week (that’s a good thing!). Not a real issue, but really did catch an open CVE.
Long passwords are bad now? ;)

Joke: Check out my app!
