🎁 Hey, let's give away software for free! Just throw some #HTML, #JavaScript, and a sprinkle of #WebAssembly into the void of the internet, and voilà, you've gifted a ticking time bomb to the world! 🤡 #Pyodide to the rescue, because who doesn't want Python apps running in a browser while you sip margaritas on a beach, free from the corporate yoke of... paying hosting bills. 🌴💸

Pydantic Releases Sandboxed Python Execution Server for AI Agents via Model Context Protocol

The #MCP Run #Python package is an MCP server that allows agents to execute Python code in a secure, sandboxed environment. It uses #Pyodide to run Python code in a #JavaScript environment with Deno, isolating execution from the host system. https://ai.pydantic.dev/mcp/run-python/

An unplanned product of the #IETFHackathon was a new #CoAP tool: https://coap.amsuess.com/view/##coaps+ws://demo.coap.amsuess.com/.well-known/core is now usable as a browser tool to fetch CoAP resources.
It is not pretty, and takes a few seconds to load, but then it's just 150 lines of code, building on aiocoap and #pyodide.

Probando por primera vez #revealjs para presentar la introducción a la programación a mi alumnado de bachillerato. Me ha gustado mucho la extensión drop de #quarto que permite implementar una consola para ejecutar código bien con la instalación en el entorno local o bien con #pyodide si decidiese colgarla online.

Have you explored WebAssembly technologies for teaching? I'd love to hear your experiences with these emerging tools for interactive data science education! #quarto #webr #pyodide #rstats #python #teaching #edtech

In this presentation, I showcase how WebAssembly (WASM) brings interactive coding directly into slide decks using Python (via Pyodide) through quarto-live - the official Posit Quarto WebAssembly backend by George Stagg.

#PyScript now has experimental support for #PygameCE !
Has anyone seen it in the wild?

TIL there is pyodide (https://pyodide.org/).

Well, should I port the FlightBox frontend and the Abelbeck Aviation Checklist to Python? 🤔

Con:
- need to dive into a new framework
- dump JS work so far

Pro:
- back on home ground! 🙂
- simplifies the code base (JS is rather awkward)

#python #pyodide #javascript #avgeek #aviationgeek

This model has me excited, web pages that asynchronously load #Python and #Pyodide for a seamless experience for the user while allowing developers to use Python.

Recently I've been working on getting #polars running in #pyodide. This was a fun one, even requiring patches to LLVM's #wasm writer! Everything has now been upstreamed and earlier this week Pyodide v0.27.0 released, including a Wasm build of Polars usable in the Pyodide REPL, Shinylive and Quarto Live 🎉

A screenshot of a Pyodide REPL executing Polars code:

import polars as pl
import requests
r = requests.get("https://raw.githubusercontent.com/pola-rs/polars/refs/heads/main/examples/datasets/foods2.csv")
pl.read_csv(r.content).group_by("category").mean()

A screenshot of a Quarto Live cell executing Polars code:

import polars as pl
import requests
r = requests.get("https://raw.githubusercontent.com/pola-rs/polars/refs/heads/main/examples/datasets/foods2.csv")
pl.read_csv(r.content).group_by("category").mean()

A screenshot of a Shinylive app using Polars code:

from shiny import App, render, ui
import polars as pl
from pathlib import Path

app_ui = ui.page_fluid(
ui.input_select("cyl", "Select Cylinders", choices=["4", "6", "8"]),
ui.output_data_frame("filtered_data")
)

def server(input, output, session):
df = pl.read_csv(Path(__file__).parent / "mtcars.csv")

@output
@render.data_frame
def filtered_data():
return (df
.filter(pl.col("cyl") == int(input.cyl()))
.select(["mpg", "cyl", "hp"]))

app = App(app_ui, server)

My #AOC day 9 - part 2 takes around 4s to run on local #python installation and 7s on pykernel which is based on #pyodide.

I see people posting in python discord that their solutions take less than a second to run! Seems like I have a lot of optimization left to do.

A couple of days ago, I shared a sneak peek of my latest project: https://fosstodon.org/@saiyalamarty/113388133530826071. Today, I’m excited to announce that we’ve added a waitlist to the landing page!

How about a #Python "Tetris" with #pyodide in your browser with pyp5js?

You know you're in deep when you're debugging by writing LLVM IR by hand. Totally worth it, though.

This requires a custom build of LLVM and rustc to compile right now, but here is a sneak preview of #polars on #pyodide, running under #wasm.

Screenshot. The polars Python package is imported into pyodide, running under WebAssembly. A DataFrame filter example is shown.

#LazyFedi There was a very cool blog post by some of the JupyterLite authors describing the technical hurdles they had to overcome to run Jupyter on Pyodide (things like running a Tornado web server without blocking the main thread etc) but I can't seem to find it... @jtp @ProjectJupyter or anyone, any clue?

#Pyodide is a port of CPython to WebAssembly/Emscripten.

Funny hackathon.

But do you want to invest time & money to dance on top of that ?
