Python packaging and distribution
INTERESTS
OPEN SOURCE
interactive and numerical computing
documentation
science (mis)communication with a splash of bad temper
stubble burning
data-driven policymaking (or the lack of it)
- misdirected resources
- vulnerable communities are disproportionately affected
- public trust in scientific institutions erodes
hundreds of packages and libraries compiled using
installable as Pyodide wheels, in the form
numpy-2.3.2-cp313-cp313-pyodide_2025_0_wasm32.whl
reproducible by design 🔒 🗂️
serverless; deployable with static website hosting providers
WebAssembly-powered Jupyter that runs in the brower
a new brand of interactive computing on small data
WASM dashboarding/apps from Jupyter notebooks
Datasette-Lite; uses Pyodide for small data
Data exploration and powerful dashboarding
new stuff with Pyodide
PyArrow
thanks to all our contributors for their hard work!
DuckDB
polars
JavaScript Promise Integration (JSPI) allows usings sync Python code with async JS, allowing Zarr, xarray, and Dask to work on the WebLoop
new packages
WASM standard improvements
to you, the viewer
- consider using in-browser frameworks to build civic tech initiatives for evidence-based environmental storytelling
- a lot of data work does not require HPC workflows, or techniques to manage big data
- WASM can be a first-class format for in-browser scientific workflows
thank you for your time!
please feel free to say hello!
