I'm super excited to join the folks from @motherduck.com at Data Outpost in November! I'll be speaking about why the investments that make SQL comfortable for humans turn out to be the same ones that make it tractable for an agent 🤖 Check out the details at www.dataoutpost.ai

📦 Introducing shinyreact for R & Python Write your UI natively in React. Shrink your Shiny server to data-only logic. Agent Skills write the React for you. ✨ opensource.posit.co/blog/2026-09... This is the start! Tell us what you build and what breaks. #RStats #Python #Shiny #React

Gave my talk "Can I offer you a nice IDE in this trying time?" at #positconf earlier today and it went well slides here: luisdva.github.io/rstats/posit...

Thrilled to have just presented "Never block, never copy. mirai + mori from Shiny to the cluster" at posit::conf(2026). The slides are available here: shikokuchuo.net/posit2026 mirai: mirai.r-lib.org mori: shikokuchuo.net/mori/ #tidyverse #rshiny #positconf2026

Day 1 of posit::conf was totally rad! 🎸 From AI data agents to @christinezhang.bsky.social's keynote on handling uncertainty (and THE NEEDLE 📈), to an 80s party with big hair! Thanks for the gnarly photo, @travisgerke.bsky.social 🤘 Ready for Day 2! 🚀 #positconf2026

It was a blast presenting on "Teaching Python with Positron" at #positconf2026. @posit.co knows how to do a data science conference. Thanks to my son Joseph for helping me put together some fun, human-made illustrations. lnkd.in/g-Y36kbk

Generative AI makes a confident-looking answer easy. Making the same answer reproducible is the hard part. Analysis should be inspectable: your data, your code, your environment, a record anyone can rerun. Prove it with Posit: https://posit.co/prove-it?utm_source=bluesky&utm_medium=social

We're excited to share commons, an R and Python package that helps data scientists build trustworthy data agents for their organizations! Read more on the @posit.co open source blog: opensource.posit.co/blog/2026-09...
