Really stoked to see @jupyter.org’s first round of community proposals get funded! It was an absolute honor to help set up this initiative! I look forward to seeing this continue in the future blog.jupyter.org/announcing-o...

We recently pushed Jupyter Book 2, which was a breaking change for many of our users! We considered publishing a completely different package (e.g., `jupyter-book2`) but decided against it. Here's a quick rationale why:

And this is how I learned about jupyter-ssh-proxy. Seems handy, and a lot less headache to set up than an actual ssh server into the hub. ✨

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! Read "Themes of Day 1, JupyterCon 2025: Collaboration and Modularity" for details: bids.berkeley.edu/news/themes-...

sad to be missing #jupytercon this week! But small win, recently made my first PR to JupyterHub fancy-profiles to add support for ARM architecture. & now I have JupyterHub running on an NVIDIA DGX Spark (via k3s). Also have CUDA/RAPIDS based image in rocker for python+R envs, rocker/cuda:arm64

One of our team goals last quarter was improving "demonstrable reliability" of our infrastructure - we've learned that making the cloud safe, predictable, and reliable is a key thing our member communities need to make the most use of their hubs

Would love feedback from anybody that follows along with this post series - doing leadership in open source often feels like invisible work, so this is one attempt at making is a bit more visible!
