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. sdsc.edu/news/2026/PR2026091…

PySM 3 only builds HEALPix skies, but you can get CAR pixelization output at the smoothing stage with a single SHT, no reproject needed. zonca.dev/posts/2026-10-06-p…

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. zonca.dev/posts/2026-10-03-h…

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. zonca.dev/posts/2026-09-28-s…

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. zonca.dev/posts/2026-09-26-m…

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. zonca.dev/posts/2026-09-26-g… #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). zonca.dev/posts/2026-09-13-a…

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. zonca.dev/posts/2026-09-01-p…

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: zonca.dev/posts/2026-08-12-p… #ChromeOS #AI

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. zonca.dev/posts/2026-07-28-c…

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. zonca.dev/posts/2026-07-20-p…

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. zonca.dev/posts/2026-07-08-j…

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. Apply: ucsd.joinhandshake.com/publi… Details: zonca.dev/posts/2026-06-03-c…

New guide: SDSC's cyberinfrastructure for AI research — Expanse, Voyager, Cosmos, NRP, and NDP. Step-by-step access for each platform. `zonca.dev/posts/2026-05-29-s…` #hpc #ai #sdsc #cyberinfrastructure

healpy 1.20.0b1 beta: harmonic_ud_grade for artifact-safe map downgrading via spherical harmonics zonca.dev/posts/2026-05-29-h… #healpy #HEALPix #CMB

PySM 3.4.5: new HalfDome TSZ model (tsz4), scipy < 1.15 pin removed, Python 3.9 dropped. Upgrade: pip install --upgrade pysm3 zonca.dev/posts/2026-05-28-p… github.com/galsci/pysm #PySM #CMB

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 🧪 zonca.github.io/jupyterlite-… zonca.dev/posts/2026-05-18-j… #Python #Jupyter

New tutorial: Deploy JupyterHub on OpenStack Magnum with OpenTofu. Kubernetes + HTTPS + custom subdomain — fully automated. zonca.dev/posts/2026-04-22-d… #Kubernetes #OpenStack #JupyterHub

Applications close TOMORROW for SDSC HPC and Data Science Summer Institute! 5 days hands-on: Deep Learning, GPU, MPI/OpenMP. Aug 3-7 San Diego. Limited to 45. Full agenda: github.com/sdsc/sdsc-summer-… Register: sdsc.edu/events/202608-HPC-D… #HPC #DataScience #AI

Just published: a notebook comparing SPT-3G D1 CMB power spectra with Planck 2018. Shows where primary acoustic peaks give way to secondary anisotropies at high multipoles. Created with a simple prompt to Sonnet 4.6.
