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


On TailwindCSS: via Simon

Tailwind is growing faster than ever and is bigger than it has ever been
Its revenue is down close to 80%.
75% of the people on our engineering team lost their jobs here yesterday because of the brutal impact AI has had on our business.
“We had 6 months left”
Listen to the founder: “A Morning Walk”
Super insightful video: Tailwind is in DEEP trouble

On Stack Overflow: See video.

SO was founded around 2009, first month had 3,749 questions
December, SO had 3,862 questions asked
Most of its live it had 200,000 questions per month
That is a 53x drop!



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? ;)
