"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!

last blog post of the year: What would a keyboard optimised for Luxembourgish look like? Now with an actual keyboard! brodrigues.co/posts/2025-1...

I can now have post-specific nix files that provide packages for single blog posts: brodrigues.co/posts/2025-1...

The least believable part of "Miracle on 34th Street" is how quickly the police arrived on the scene when Santa was arrested

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.

Merry Christmas!

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

done!

soon...

time to install nixos on this thing

just compiled my first program for macOS and the .dmg is marked as damage unless I pay Apple 99$ a year? lmao (yes I know I can run xattr -cr path to app but that sucks for the users)

this is the prototype of what I'm working on running on my mac (client) and on my Linux pc (server): seemless pair programming using upterm for shared sessions with automatic dev env setup using nix! Real-time collaboration will be the next milestone before public β testing

Today was my first day as "Senior Vibe Coder" at Cloudflare , I pushed some updates to prod, people should start seeing improvements soon!

Luxembourg used to be safe but now not so much! went to my favourite coffee place and left to go to the bathroom and when I came back someone had installed windows 11 on my laptop!!! stay safe out there

I like to use the chat interfaces wich LLMs and this is the quickest way I found to upload a code base to an LLM before starting a coding session

`treemerge`: github.com/b-rodrigues/... treemerge scans a directory tree, detects all plain-text files, and concatenates them into a single output file with clear per-file headers. It offers a configurable way to assemble large text corpora for supplying contextual input to LLMs.

And it's easy to test out! It's def worth knowing it's an option. The vignettes @brodriguesco.bsky.social wrote are pretty good, too. It might not be for you, but it might be 😁 docs.ropensci.org/rix/referenc...

WHERE IS THE BISCUIT

It's just so easy.

thank you #RStats 🙏

new blog post: Of course, someone has to write imperative code to build reproducible data science pipelines. It doesn’t have to be you. brodrigues.co/posts/2025-1...

NOOOOOOOOOO DON'T START EXPLORING DATA IN A JUPYTER NOTEBOOK!

wanna try the latest R 4.5.2 and bioc 3.22? rix::rix( date = "2025-11-01", r_pkgs = c("dplyr") ) #RStats #Nix

I find Luxembourguish fascinating. This word is constituted of the German "Gesundheit" (health) and the French "Donnée" (data). In French, pluralized words get an 'S' at the end, but in German 'en'. In LB, even though "donnée" comes from FR it gets pluralized as in DE

It's difficult not to act arrogant when you see how #Nix elegantly solves so many problems (comprehensive dependency management and universal binaries to name a few) when you see this being re-solved by other half-baked solutions.

#Nix for Polyglot, Reproducible Data Science Workflows Many thanks for the feedback, I think that this version is now much better: github.com/b-rodrigues/... if you want to read it online instead: b-rodrigues.github.io/rix_paper/ I aim for a submission before the end of the year!

New blog post: Orchestrating Polyglot, Reproducible Data Science with Nix and {rixpress} brodrigues.co/posts/2025-1...

Also available in html format (all with the magic of quarto + github pages) b-rodrigues.github.io/rix_paper/

if someone wants to give feedback on a paper i’ll be submitting soon titled "Nix for Polyglot, Reproducible Data Science Workflows" that’d be greatly appreciated! github.com/b-rodrigues/...

I told claude to review, very critically, a little project I'm doing and he gave me micro-econometrics seminars flashbacks

look how beautiful

This is an example of how Nix can be useful for data analysis: a project that uses @julialang.org #Python and #RStats in which #Nix is used to set up the dev env in a reproducible way, and is also used as build automation tool to orchestrate the codebase b-rodrigues.github.io/rixpress_dem...

compiling the latest @julialang.org from source on #NixOS

This may just be the best CS paper I’ve read this year. Just read the abstract and first para of the intro! The rest of the intro is really wild too, but very very good: dl.acm.org/doi/pdf/10.1...

I think the reason is that file system is the natural predator of the data scientist. At least with jupyterlab, data scientists are able to find where they've saved their files more easily.
