This was #VizChitra2026! 2 days, 600+ community members, Bengaluru & online. Our first sold-out conference! Thank you for showing up, sharing so openly, and making VizChitra a little bigger, a little warmer, and a lot better than we had initially dreamed. Until next time! 💙

Thanks for the shoutout on the podcast, @trudeau.dev! I built marimo-tutorials (with contributors) early on to show off @marimo.io's features across a bunch of domains. Later helped spearhead marimo-learn too, which is now a community-driven project with notebooks on all sorts of topics.

Episode #301: Running Python Locally in a Sandbox – The Real Python Podcast

How do you avoid the risk of running a Python application locally that could be malicious, break your code, or leak private data? How can you create a sandboxed local environment using WASM and…

We’re bringing @scipy.in to Noida this August alongside Rust Delhi and the CFP is officially open!! If you are working anywhere near the intersection of Rust and Python for science or data, check out the links in the post below to speak or attend.

Thought we were inactive? Far from it!! We’re hosting a meetup on Scientific Computing in Rust & Python on Aug 22 in Noida, co-organized with Rust Delhi and sponsored by the Rust Foundation! 📝 CFP Open: scipy.in/sci-py-rs/ 🎟️ RSVP: www.meetup.com/rustdelhi/ev... (1/3)

The CFP for the Documentation & Technical Writing Devroom at FOSSUnited's IndiaFOSS 2026 is open! Last year, the FOSS in Science devroom helped kickstart the @scipy.in community. We’re hoping this devroom can do something similar for @writethedocs.bsky.social India. Link in the thread 🧵

Co-organized the Apache kafka Chennai meetup yesterday (hosted by the @confluent.io folks) and gave a talk on @cocoindex.bsky.social's new Kafka connector. Full recap + slides in the replies, go check them out!!

Visited @iitmadras.bsky.social for ChennaiFOSS 2026. Managed to spot some deer and blackbucks on the way in, which was a definite highlight!! Spent most of the day at the @scipy.in booth catching up with the FOSSEE team and others... Blog post: haleshot.github.io/posts/chennaifoss-2026-experience/

Was in Bangalore last weekend for @github.com Constellation. Saw an early preview of the revamped landing page & @mvkaran.bsky.social had some cool livecoding demos! Also got to ask GitHub's COO about AI-generated PRs flooding the open source ecosystem. Detailed Blog post in the thread...

Spoke at OpenSourceDay in Gandhinagar on community building during my time at @marimo.io (touching on user engagement, sharing examples, and teaching in public). Wrote my reflections from the talk (and event on the whole) here: haleshot.github.io/posts/osd-20...

Wrapped up the previous weekend at @wikimediafoundation.org's Developer Skill Development Program India, running a technical writing workshop and learning from folks building tools for Indic-language communities. haleshot.github.io/posts/wikime...

Spent the weekend at PyConfHyd representing @scipyindia.bsky.social; met familiar faces, had some really good conversations around the booth, and enjoyed catching up with folks. Also really enjoyed Parul pandey's keynote. Wrote a blog post about the experience: haleshot.github.io/posts/pyconf...

We wrapped up our first joint meetup with BangPypers last Saturday in Bengaluru; hosted at Amadeus Software Labs. Full writeups from both sides: 📝 SciPy India: scipy-india.github.io/blogs.html?i... 📝 BangPypers: bangalore.pythonindia.org/blog/2026/02...

We're excited to partner with FOSS United for FOSS Hack 2026!! It's India's largest FOSS hackathon, running March 1-31, hybrid, bringing together students, professionals, and open-source communities to contribute across code, design, documentation, hardware, etc. #opensource #hackathons #foss

Been wanting to get @scipyindia.bsky.social and BangPypers in the same room for a while. Last saturday, it finally happened! Three talks, 2 lightning talks and getting people excited to contribute / volunteer. That's why we keep pushing for offline meetups :)

An anecdote from building in the open: someone sees your work on @github.com, reaches out with a need, you build for it, they test the branch (not even after it's on main) and confirm it solves their problem. That direct feedback loop is genuinely fulfilling!

Kicking off 2026 with Rust Delhi Meetup #12, and what a way to start. Thanks to Guinnes Singh for accepting my talk proposal & being a great host throughout. I presented on building incremental data pipelines with @cocoindex.bsky.social, a framework I've been contributing towards. (1/n)

CocoIndex made to #1 Github trending global in Rust - data transformation engine. Grateful to the Rust open source community and all the amazing Rustaceans for the support 💛 #rustlang #github #opensource
