My notes from MenderCon 2021, an open space conference on modernizing and improving existing codebases.

In this article you’ll learn how to run your PHPUnit tests whenever a PHP file changes. This is useful if you don’t use an IDE that does this or want to share the results during a pairing session where only one party has access to a PHP execution environment. With the command line tool entr you can watch for changes in a list of files and run a command whenever one of the files changes.

This post shows my step-by-step journey using the Vue composition API in a Vue project that uses Vuex. I started with the question “How can you gradually introduce the composition API without having to rewrite everything?”

“The Legacy of SoCraTes” is a virtual conference with talks on testing and legacy code. You can find all the talks of the 3rd edition in the YouTube playlist for the conference.

This article is a summary of some talks.

In June I attended JS Nation Live, an online conference on JavaScript. I took notes during most of the events and added some opinions and lots of links afterwards.

2019 was the first year I have participated in the Advent of Code challenges, encouraged by my colleague Jan. I wanted to make it an opportunity to learn new programming languages and focus on functional programming. I started with Racket, tried out Elixir and re-wrote the challenges that involved the “intcode computer” in Scala. This post is a review of the programming languages and the event itself.

I participated in the Global Day of Coderetreat, practicing on the Game of Life Kata and heard that some people solved the problem of finding neighboring cells with a Cartesian Product. I did not see their solution, but tried out figure out my own solution. I learned something about JavaScript, functional programming and performance, which I will share in this article.

When I want to check out a GitHub pull request of my colleagues on my local machine, I usually have to open my browser, go to the pull request page on GitHub, copy the branch name, do a git fetch in my terminal, followed by a git checkout, pasting the branch name. Annoyed by this context switch between terminal and browser and all that mouse movement, I devised a way to select the pull request from a list in the terminal, with a checkout when I hit Enter:
