Interactive tutorials rot fast: login chains change, consoles move buttons, versions drift. CI cannot see any of it.

New post: an orchestrator plus two AI subagents, a browser executor and a docs improver, keep them honest.

New post: I now write slides in Markdown with Marp. Same repo as the docs, readable git diffs, and AI agents can edit them and render PNGs to check every slide.

Clean theme + example deck:

New @SDSC_UCSD article on the 2026 HPC & Data Science Summer Institute that I chair — researchers and educators got hands-on with GPU programming, deep learning, and Python for HPC. https://t.co/W8kBwbUXxq

PySM 3 only builds HEALPix skies, but you can get CAR pixelization output at the smoothing stage with a single SHT, no reproject needed.

healpy 1.20.1 released - the last release with macOS 14 arm64 wheels, before GitHub retires the macOS 14 runner (Nov 2). Includes rotate_alm and lonlat2thetaphi fixes, plus column_units for write_cl. https://t.co/yfbl1lHLn7

Just published a practical primer on software citation. A 7-step workflow for citing software and a 5-step framework for making your own software citeable, from the 2026 Software Citation Workshop at UCSD. https://t.co/LLyRkILk0d

I replaced Trello with GitHub Projects + AI agents for managing my events. All plans, decisions, people, and agreements live in one repo; the agent drafts emails and proposes next actions ("check issues" / "Go") while I approve everything. https://t.co/yvklX8ihhy

Gateways 2027 is coming to San Diego, hosted at SDSC! I'm honored to be its chair. A conference by and for the community: join the program committee, nominate a keynote, or propose a BoF, hack day, or workshop. https://t.co/eoaGqVp5vg #Gateways2027 #ScienceGateways

New tutorial: color-code your AI agent terminal windows so ChromeOS Overview shows which agent is still working (gold) and which is done (green). https://t.co/tSc8tSv6eD

I heavily rewrote my Python for HPC session for the 2026 SDSC Summer Institute. Notebook-first, timed flow: Numba to Dask, then multi-node on two Expanse nodes. A PySM dust kernel shows Numba in a real codebase, plus an optional AI-coding-assistant block. https://t.co/qacxulUVDk

AI agents in Chromebook Linux can generate PDFs, images, and HTML—but opening them in ChromeOS Chrome is awkward. I built a small skill that bridges Crostini with a Python HTTP server + garcon-url-handler.

Guide and code: https://t.co/OrKtGUeNvu

#ChromeOS #AI

[Andrea Zonca @andreazonca]

AI coding agents in Crostini usually launch a separate browser, losing the tabs, cookies, and logins in ChromeOS Chrome.

I built a durable Playwright bridge so any agent can control the existing profile safely.

PySM 3.4.6 is out, with two new FLAMINGO kinetic SZ presets: `ksz5` and `ksz6`. This notebook demonstrates the standard PySM workflow and compares them with WebSky and AGORA at 143 GHz.

I built a minimal blogging skill that delegates post creation to Jules (Google async agent). I dump raw notes + links, it reads AGENTS.md and produces a formatted post. Works for any static site. https://t.co/dXoLd1bsVH

Call for student volunteers! SDSC Summer Institute 2026 needs UCSD undergrads to help with HPC/data science training. Earn CCR credit on your transcript. Basic Linux + Python skills enough.

@_mohansolo Quickly?? That is an understatement. 20 minutes without even coding and flash was gone

Running a Python workshop? You might not need JupyterHub 🐍

JupyterLite runs Python in the browser — no server, no setup. NumPy, SciPy, Pandas, scikit-learn all work via WebAssembly 🧪
