I had such a good time at JupyterCon. Great to see all those faces in real life that I'd only seen on a screen before. What an awesome community :)
So much activity at #JupyterCon 2025 -> tutorials 🧠, meetups 🤝, talks 🎤! Thankfully, Silas Santini captured some highlights and shared some valuable resources!

Would you prefer that QGIS opened new projects with a reasonable default basemap? Or do you prefer a blank canvas? Why?

It's 2025, and I’ve finally updated my Python setup guide to use uv + venv instead of conda + pip!
Here's my go-to recommendation for uv + venv in Python projects for faster installs, better dependency management: github.com/rasbt/LLMs-f...

By definition, numerical weather models require international data. The atmosphere knows no geopolitical boundaries: any model that begins and ends at its country’s border is unable to generate reliable predictions until after a weather system crosses its boundaries. Which defeats the purpose!

An internal email obtained by WIRED shows that NOAA workers received orders to pause “ALL INTERNATIONAL ENGAGEMENTS.”
