Here’s why nixpkgs is a GitHub repository that contains tens of thousands of Nix expressions used by the Nix package manager to install software. By default, the nix package manager will pull expressions from NixOS/nixpkgs, but when using...

Happy new year! The blog has a new look! Well it’s not that different on the surface. But under the hood, it is quite different indeed! My previous setup was: GitHub to host the code, on each push the build process would get started on Net...

Nix is not only a package manager, but also a build automation tool, and you can use it to build polyglot data science pipelines in a completely reproducible way. For example, suppose that you need to mix Python, R and maybe some others tools for a project (by the way, ...

Simplifies the creation of reproducible data science environments using the ‘Nix’ package manager, as described in Dolstra (2006) . The included ‘rix()’ function generates a complete description of the environment as a ‘default.nix’ file, which can then be built using ‘Nix’. This results in project specific software environments with pinned versions ...

Intro I have this package on CRAN called {chronicler} and last month I got an email from CRAN telling me that building the package was failing, and I had two weeks to fix it. I immediately thought that some dependency that my package d...

I’ve very recently started contributing to the nixpkgs repository of packages, which contains all the packages you can install from the Nix package manager. My contributions are fairly modest: I help fix R packages that need some tweaking to make them successfully build for Nix. Most of these fixes ...

After 5 months of work, Philipp Baumann and myself are happy to announce that our package, {rix} is getting quite close to being in a state we consider “done” (well, at least, for a first release). We plan on submit it first to rOpenSci for review, and later to CRAN. But ...

This is part 8 of a series of blog posts about Nix. Check out the other parts here. TLDR: free and open source software is one of the most important common goods with enormous positive externalities: if you want to help funding it, keep reading! I wanted to quickly discuss about ...

Back in June I self-published a book on Amazon’s Kindle Direct Publishing service and wrote a blog post detailling how you could achieve that using Quarto, which you can read here. The book is about building reproducible analytical pipelines with R. For the purposes of this post I made ...

Now for something completely different than our usual programming: today I’m sharing my thoughts on the latest ZSA mechanical keyboard, the Voyager. First things first: this is in no way shape or form sponsored by ZSA. But Erez, if you’d l...
