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 like to send me money you’re more ...

Warning: I highly recommend you read this blog post first, which will explain how to run a pipeline inside Nix in detail. This blog post will assume that you’ve read that one, and it would also help if you’re familiar with Github Actions, if not, read this other ...

This blog post is a copy-paste from this vignette Introduction This vignette will walk you through setting up a development environment with {rix} that can be used to compile Quarto documents into PDFs. We are going to use the Quarto template for the JSS to illustrate the process. The first ...

For this blog post, I also made a youtube video that goes over roughly the same ideas, but the blog post is more detailed as I explain the contents of default.nix files, which I don't do in the video. Watch the video here. This is the fourth post in ...

This is the third post in a series of posts about Nix. Disclaimer: I’m a super beginner with Nix. So this series of blog posts is more akin to notes that I’m taking while learning than a super detailed tutorial. So if you’re a Nix expert and ...

This is the second post in a series of posts about Nix. Disclaimer: I’m a super beginner with Nix. So this series of blog posts is more akin to notes that I’m taking while learning than a super detailed tutorial. So if you’re a Nix expert and ...

This is the first of a (hopefully) series of posts about Nix. Disclaimer: I’m a super beginner with Nix. So this series of blog posts is more akin to notes that I’m taking while learning than a super detailed tutorial. So if you’re a Nix expert and ...

UPDATE: I’ve update this blog post on the 30 of June 2023. I corrected a statement where I said that the _quarto.yml file is where you can choose the version of R to compile the book. That’s wrong, choosing the version of R to compile the book is done ...

Last year I wrote a post about dockerizing {targets}’s pipelines (link to post) and between that blog post and this one, I’ve written a whole book on building reproducible analytical pipelines that you can read here (for free!). In the book I explain how you can build projects ...

I’ve been blogging for 10 years, actually even a bit more than that, my very first blog is not online anymore and if I remember correctly was in French. I think it was around 2010 when I was a Master’s student. Anyways, here are my thoughts on why I think ...

Unfortunately not everyone knows about literate programming so many tables in Word documents are “generated” by hand (generated is really too strong a word) and what very often happens is that these handcrafted tables have typos. Usually it’s totals that are wrong. Checking the totals in these tables by ...

Data scientists, statisticians, analysts, researchers, and many other professionals write a lot of code. Not only do they write a lot of code, but they must also read and review a lot of code as well. They either work in teams and need to review eac...

I’ve been working on an ebook (that you can read over here) made using Quarto. Since I’m also selling a DRM-free Epub and PDF on Leanpub I wanted to share some tips and tricks I’ve learned to generate an Epub that passes epubcheck using Quarto. Quarto is ...

You expect me to read this long ass blog post? If you’re too busy to read this blog post, know that I respect your time. The table below summarizes this blog post: Need Solution I want to start a project and make it reproducible. {renv} and Docker There’s ...

I’ve been working on a way to evaluate how old R code runs on the current version of R, and am now ready to share some results. It all started with this tweet: The problem is that you have to find old code laying around. Some people have found ...

I’ve had some discussions online and in the real world about this blog post and I’d like to restate why containerization is needed for reproducibility, and do so from the lens of functional programming. When setting up a pipeline, wether you’re a fu...

This blog post is a summary of Chapters 9 and 10 of this ebook I wrote for a course The goal is the following: we want to write a pipeline that produces some plots. We want the code to be executed inside a Docker container for reproducibility, and we want this container ...

Open source is a hard requirement for reproducibility. No ifs nor buts. And I’m not only talking about the code you typed for your research paper/report/analysis. I’m talking about the whole ecosystem that you used to type your code. (I won’t be talking about making ...

This blog post is taken from a chapter of my ebook on building reproducible analytical pipelines, which you can read here If you want to follow along, you can start by downloading the data I use here. This is a smaller dataset made from the one yo...

This blog post is divided in two parts: in the first part I’ll show you how to create a Linux Live USB with persistent storage that can be used as development environment, and in the second part I’ll show you the easiest way to set up RStudio and ...
