Let's be real - most of Python tests are waste of time High-value tests are pure gold. Read about their 7 qualities in my latest post. python-testing.com/python-testing…

Claude Code leaked their source map, effectively giving you a look into the codebase. I immediately went for the one thing that mattered: spinner verbs There are 187

I think I finally understand what an agent is. It's a prompt (or several), skills, and tools. Did I get this right?

Django: One ORM to Rule All Databases #python paulox.net/2025/10/06/dja…

10 Concurrency Concepts you must learn for backend: 0. Thread Safety (race conditions) 1. Locks (Mutex, R/W locks) 2. Optimistic vs pessimistic locking 3. Lock-free/CAS (compare-and-swap) 4. Deadlocks (detection/prevention) 5. Thread pools 6. Futures & async programming 7. Backpressure (producer/consumer) 8. Context switching overhead 9. Event loops vs threads

Clean code is not about naming things perfectly. It’s about: - making intent obvious - reducing cognitive load - helping the next developer (often future you) Readable code scales better than clever code.

With agentic slop, we are trading software reliability for shipping velocity and calling it progress. It isn't. Systems are more fragile than ever, and engineers building them no longer trust their code to hold up in real-world edge cases. I am pro-AI, but this will backfire - big time.

I second this, passionately! better-simple.com/django/2026/03…

Python 3.15's JIT Is Now Back on Track fidget-spinner.github.io/posts/jit-on-t…

I wrote a post on how we tracked down slow imports in our Django app, fixed them by making imports lazy, and added a lint check to prevent regressions. Now I’m waiting for Python 3.15 to make all of this easier! 🚀 blog.pecar.me/speeding-up-dj…
