We have summer internships y'all! Come work at Posit on the PyData, tidymodels, shiny, or Connect teams: grnh.se/tigz810a3us. You will have an awesome time, learn a ton, and help advance our open source and pro tools 🧰 #rstats #pydata

We’re thrilled to welcome Sara Altman and Simon Couch of the Posit AI Core team to the #positconf 2026 keynote stage! They’ll be sharing a practical, hype-free look at how AI is being thoughtfully integrated into the tools you use every day. ✨ See what’s next for AI in open source: pos.it/conf

Not sure how we went from plain, straightforward words to LinkedIn speak but now you can use Kagi Translate to fit right into that crowd: translate.kagi.com?from=en&to=L...

The flip side of this for enterprise Claude users is getting work done early east coast hours before the west coast wakes up

Humans AI Agents 🤝 CLI tools Coming soon to btw, an #RStats cli tool for agents and humans

Does anybody here use `gh` with 1password and have a good way to let Claude Code use `gh` without constantly needing my fingerprint?

You're doing awesome work and we want to hear your stories! Submit a talk for posit::conf(2026) - Today is the last call for talks!

Until humans get better at writing issues and describing PRs, I’ll happily accept AI-assisted submissions

Not-AI detection: you can tell that I hand-crafted the PR description by the number of times I said "basically"

Can you learn AND offload? Yes. We do it all the time across our days. You just cannot do every single thing at once, and have to think about the structural support for different (sometimes competing) goals. Self-regulation isn't new, but it is a vital skill for developers now.

Registration is LIVE for posit::conf(2026)! Join us in Houston or virtually from Sept 14–16 for workshops, 100+ talks, & a whole lot of data science. ✨ Super Early Bird: Save on in-person tickets until April 10 ✨ Virtual Pass: $99 for a virtual day+livestreams Secure your spot: pos.it/conf

all I want to do is code and make shiny apps

I forgot to share my favorite skill, a slop-catching adversarial code review skill that gives brutal and surgical reviews inspired by @dollspace.gay's sarcasmotron agent. Even Claude said "are you sure you want to be this antagonistic?" when it reviewed the skill text 😂 github.com/posit-dev/sk...

The fact that #rstats packages ship docs *with* the code itself is a super power in the age of AI coding assistants. If you have the package, then you have the docs, and you can use tools like btw to connect those docs to your assistant posit-dev.github.io/btw/referenc...

Getting tired of typing the same workflow prompts over and over in Claude Code, so now I’m just making skills for everything Lower the bar for skills! You can make skills for your favorite workflows or phrases you keep repeating What skills have you made lately? Here are a few of mine

“What we’re hoping to do is develop lots of smaller pieces and somehow satisfy ourselves that they all work individually. This is the running theme through most of my advice.” Lots of great advice in here

"Ten simple rules for teaching data science": arxiv.org/abs/2602.02874 A new preprint by @minecr.bsky.social and myself. We'd love any feedback!

We don't need little AI chatbot assistants in *every app*, but Atlassian's Rovo agent is now the only way I can use Confluence to find anything

Had a great time on @posit.co 's Test Set pod w/ @mchow.com @hadley.nz @wesmckinney.com! We talk about moving between R, SQL, python and the strengths of different analytical tools for diff data tasks. You won't believe what proprietary language gets a shout-out (Stata!) posit.co/thetestset/e...

This is a super cool little app to pick out a palette of colors from a picture. Fun interface but the algorithm is so good

Oops, I started a new project: Skyreader, an RSS reader on the AT Protocol. Share cool articles like it's 2010 and Google Reader would never die. skyreader.app www.disnetdev.com/blog/2026-01...

Whenever I read discourse on AI energy/water use that focuses on the "median query," I can't help but feel misled. Coding agents like Claude Code send hundreds of longer-than-median queries every session, and I run dozens of sessions a day. On my blog: www.simonpcouch.com/blog/2026-01...

Speak at posit::conf(2026) and share your R & Python stories! Accepted speakers get: ✨ Travel & lodging help ✨ Free conference pass ✨ Professional coaching Apply by Feb 6 to join us Sept 14-16 in Houston, TX! Submit here: pos.it/conf-talk-2026 #positconf2026 #rstats #pydata

Soooo if you use #RStats and Claude Code: R console: install.packages("btw") Terminal: claude mcp add -s "user" r-btw -- Rscript -e "btw::btw_mcp_server()" And now Claude Code can answer questions about ANY R package installed on your system.

Happy UTC New Year!! 🎉 🥂

Turn Claude into an expert on writing {testthat} #Rstats 📦 version 3 R tests with the Claude Testing R Packages skill by @posit.co github.com/posit-dev/sk... That repo has other skills including how to use brand.yml with Quarto and Shiny github.com/posit-dev/sk... #GenAI

oh! Also in this release: 4 new tools for common #RStats package dev tasks: running tests, checking test coverage, running R CMD check and rebuilding documentation. These tools are a great way to get Claude Code and Codex to run tests 🧪 without burning tokens 🔥 posit-dev.github.io/btw/referenc...

Happy holidays! 🎄 I snuck in a {btw} release just before CRAN went on vacation for the year. {btw} is an #RStats package full of tools for LLMs, including a new tool for running R code. Here's a quick demo using `btw_app()` to create a quick festive ggplot2 from holiday movie titles. Cheers! 🧑‍🎄

I see a lot of complaints about untested AI slop in pull requests. Submitting those is a dereliction of duty as a software engineer: Your job is to deliver code you have proven to work simonwillison.net/2025/Dec/18/...

For months I've had a pesky message that shows up in my #RStats test logs and today I realized I can figure out exactly where it's coming from with testthat's location reporter Rscript -e 'devtools::test(reporter = "location")' 2>&1 | tee test.log

One of the many reasons AI can't produce good writing is it can't hate its own writing. It can't think to itself "Maybe I'm illiterate" during the writing process. And that's essential

For…reasons, I've been investigating non-US alternatives for some of the services I use. TIL that @BunnyCDN offers a drop-in replacement for Google Fonts: fonts.bunny.net/ Also Bunny itself is a great EU-based alternative to most of what Cloudflare offers.

Offcanvas 1.0.0 for Quarto is now available.

My R+AI Conf talk is now available on YouTube: youtu.be/828KuEORQdg?... I talked about my R package {brandthis} that helps you getting started with theming your quarto outputs and shiny apps by quickly generating brand.yml files and color palettes for R and Python plots #RStats

testthat 3.3.0 out now! This is a massive release with tons of improvements including better failure messages, new expectations, improved snapshotting, new vignettes, and much much more: tidyverse.org/blog/2025/11... Post includes some thoughts on developing an #rstats package with Claude Code.

Dr. Cat Hicks (@grimalkina.bsky.social) gave one of my very favorite keynotes of all time at #positconf this year 🥹 It really made my heart glow, and now that all the conf talks are on YouTube, you can watch it even if you missed conf!! #databs #rstats #python www.youtube.com/watch?v=B-bM...

I've been dipping my toes in package development for #lua, #python, and #bash and #rstats friends -- let me tell you I didn't realize how good we have it with {devtools} , {usethis}, and the rich supportive rstats community

Tomorrow morning! Come by!

If you use AI to write a PR, then *you’re the first reviewer*. And if you’re asked to review unreviewed AI-generated code, here’s a great template for your first review.

Full schedule is live: R+AI 2025 · Nov 12–13 · online Sample session: “Tools for LLMs and Humans who use R” — Garrick Aden-Buie (Posit) How the {btw} package feeds computational context to LLMs for smoother R+AI workflows. Register! rconsortium.github.io/RplusAI_webs... #rstats #AI @posit.co

Happy logical Halloween

This morning my ChatGPT quota was inexplicably exhausted. It took a while but I pieced it together. Voice mode somehow got activated when I went to bed. The bot then engaged in a 10 hour conversation with my snoring dog, answering questions the pup wasn’t asking and praising him for his insight.

R+AI 2025 • Nov 12–13 • Online • Low-cost Skip the hype. See how R + AI works in production! Keynote: Joe Cheng (Posit) on focused, reliable LLMs for data science Actionable R+AI sessions. Students from $25. Register: rconsortium.github.io/RplusAI_webs... #rstats @posit.co @jcheng5.bsky.social

I'm a big fan of this idea! I need to write a blog post on this, but bslib + brand.yml + pkgdown's light switch is a killer combo for branded pkgdown sites with light/dark themes. The {btw} site is a good example posit-dev.github.io/btw/ All the magic is in _pkgdown.yml github.com/posit-dev/bt...

I really appreciate everyone agreeing with me 😆
