This is a very short article to share Swirly, a Command Line Interface-based tool to learn python (or any python package) interactively. ...

I have a template of a document written as an org file. I have to edit some fields in that file to be able to generate different versions of that document for different people. I export it as a text file to give the feel of a document written with an old-school software and printed with a dot matrix printer. Finally I convert the produced document to PDF. ...

I recently faced the following problem: I had a PDF document created by merging several other documents, many of them containing multiple pages. I needed to display the page numbers in the document. Latex and pdftk to the rescue! ...

In this blog post, I want to show how I configured mu4e to read my Gmail accounts in Emacs. ...

I work with many RMarkdown files structured within a hierarchy of directories. I needed to render these files to PDF and then use Ghostscript to merge them. This article explains the two small shell scripts I used for the task. ...

It was very easy to configure Elfeed in Emacs to have all the blogs and news from the sites I like, together in Emacs. In this short article, I share how I configured the Elfeed package with the RSS feeds of some of the blogs I enjoy reading. This is important for me because I often spend time filtering through a lot of content that I am not interested in on forums like lemmy.ml or reddit.com.

There are some operations with pandas that I often forget. This site exists exactly for that: to remind me how to perform these tasks. In this post, I’ll cover some very basic pandas operations that I often forget, including dropping columns, reordering columns, and changing the names of columns. ...

Dates and date-time objects are some of the most challenging data types to work with. They can come in a variety of formats (long live ISO 8601!), may have different time zones, and introduce considerable complexity as a result. ...

In legal documents in Spanish language it is often necessary to include the “value in words” of a number—for example, $2400 (dos mil cuatrocientos pesos). I created the package spanish2 to automate this task. If you are curious to learn more about this package, please keep reading. If you’d like to install it or view its code, you can access its GitHub repository. Writing this package inspired this article about how to write an R package using Emacs and ESS (Emacs Speaks Statistics). You might want to check it out! ...
