Episode notes
Name-Space Off-By-One Cost Days
- Pablo Galindo shared a personal bug hunt where an off-by-one handling of a space in his surname blocked access to tax docs.
- He blamed a string-splitting error that required human support to resolve, illustrating fragile input handling.
Free Threading Became Real
- Free threading (PEP 703) shipped in Python 3.14 and allows pure Python programs to scale across CPU cores.
- Community and major projects (NumPy, PyTorch, SciPy, etc.) quickly adopted support, easing ecosystem transition.
Test Pre-Threaded Wheels In CI
- Add pre-threaded Python to your CI matrix so you catch concurrency issues early.
- Use CI Build Wheel to automatically produce pre-threaded wheels for Python 3.14.
