In T, pipelines are first-class, and it's possible to run R or Python code. Right the pipeline code, with some nodes running #RStats code, and other #Python code.

#rstats 4.5.3 "Reassured Reassurer" scheduled for March 11. Full schedule on developer.r-project.org (or the svn if you're impatient.) This should be the wrap-up release for the 4.5 series.

I think the main issue is that many people, quite reasonably tbf, don't like the default base data.frame print method... But this is easy to override! gist.github.com/grantmcdermo...

The language I'm working on, T, a reproducibility- and pipeline-first DSL for Data Science, has now a basic packaging system. Say hello to `hello_t`, the very first package for T! github.com/b-rodrigues/...

In the large: Mortality in France, 1816-2016.

join me to create the next programming language for data science: powered by #nix, #ocaml and #arrow, heavily inspired by #RStats tidyverse and designed to facilitate collaboration with LLMs!

cuplyr version 0.1.0 is now out! A GPU-accelerated dplyr backend for R, powered by RAPIDS cuDF. Write familiar tidyverse code, execute on GPU. Lazy eval with AST optimization. In my benchmarks 60x faster than dplyr on 50M rows. github.com/bbtheo/cuplyr #rstats #cuda #DataScience

there might be no point in developing yet another programming language in this day and age, but it sure is fun!

join me with your LLMs to make T a reality github.com/b-rodrigues/...

unigd has been removed from CRAN, but jgd might be worth checking (I understand it’s a super early alpha): github.com/grantmcdermo...

The first data science book that has a chapter on monads reproducible-data-science.dev Learn how to build robust #DataScience pipelines with #RStats, #Python , #Julia and #Nix !

Alright, so even just reading Chapter 2 is worth it for anyone interested in using `rix` (*you* should be interested in using `rix`, because it's great). #rstats

The first data science book that has a chapter on monads reproducible-data-science.dev Learn how to build robust #DataScience pipelines with #RStats, #Python , #Julia and #Nix !

Btw, the latest rixpress version now supports Sub-Pipelines! rixpress: reproducible analytical pipelines in #RStats, #Python and #Julia using #Nix as the underlying build tool!

8 minutes from submission to publication, thank you CRAN team

New preprint alert! @felipefv.bsky.social, @brodriguesco.bsky.social and myself try to walk you through how to make your simulation study computationally reproducible. @felipefv.bsky.social did some great work—fun paper to work on. TLDR: Use Nix felipelfv.github.io/Why-risk-it-...

I give talks where I talk about reproducibility with #Nix for #RStats users (mostly researchers), any such user groups of #Python practitioners I could talk to as well?

#RStats📦rix 0.17.4 is out! Major #Python QoL improvements: automatic LD_LIBRARY_PATH setup for easy integration with uv, new py_src_dir for editable-style Python dev in #Nix shells, and smarter cachix detection (no more noise on #NixOS). Plus docs cleanup & cache setup updates

Please people, I beg of you, use Nix!

New #RStats Blog post: From scripts to pipelines in the age of #LLM s brodrigues.co/posts/2026-0...

I sent 200 pull requests using Claude Code and wrote about the experience. It's pretty wild! For dplyr releases, we send a PR any time we break an #rstats package. This release advances a lot of deprecated functions, triggering issues in many old packages! blog.davisvaughan.com/posts/2026-0...

Reproducible Polyglot Data Science still a WIP, but I think there's already quite a lot of useful content. Will stay free forever: reproducible-data-science.dev buy me an espresso to show your support: buymeacoffee.com/brodriguesco

New blog post: Don't fall into the anti-AI hype. antirez.com/news/158

what the recent Tailwind drama showed is that the primary audience for tech books/docs is going to be LLMs now, no one's going to read anymore, not that people read anything before. Just upload a book's PDF and ask for a TLDR. Future tech docs will be written with this in mind

Tired of LLMs hallucinating R/Python function names? pkgctx extracts real API specs from packages — signatures, arguments, examples — into a compact YAML file you can paste into any LLM. Works with CRAN, PyPI, GitHub, or local packages. github.com/b-rodrigues/...

in 2026, take some time to add Nix to your data science toolbox, you won't regret it! Using my packages rix and rixpress is becomes trivial to build completely reproducible data science pipelines!

"Nix for Polyglot, Reproducible Data Science Workflows" read it here b-rodrigues.github.io/rix_paper/

paper submitted, let's see how it goes!

in 2026, try new software!

Luxembourg has three official languages (lb, fr and de) and english is used a lot as well. This is the heatmap of an optimized keyboard layout that tries to shift as few keys as possible, based on the most-used layout in Luxembourg, the CH-FR (or CH-DE) currently for Luxembourg.

I can only recommend getting a second hand m2 macbook (with 16gigs of ram) and installing linux on it. Do so asap, before normies hear that RAM prices are increasing!

and here is why, even though I'm no fan of Apple, I decided to buy a macbook and install nixos on it: even when compiling packages with a 100% load on the CPU, I still have several hours of battery
