Stuff I learned while trying to implement proper error management in Python code.

A small example of a innocent-looking C++ refactoring going terribly wrong and how to fix it.

Introducing tsrc, a tool to manage multiple git repositories and automate GitLab interaction.

Welcome!

This article will be a guided tour of how I use git.

We’ll talk about configuration of git itself, the aliases and scripts I’ve written, and the other tools I work with.

Some tips on how to use and customize vim-ale, an asynchronous lint engine for Neovim and Vim 8

How I failed to make my first contribution to the Python programming language, and what I learned from it.

Last month I wrote about how I rewrote z from scratch after I started using fzf.

10 days later I posted the following toot on Mastodon:

There’s a problem with my implementation: ‘recent’ paths only get priority after they’ve been accessed enough times.

There’s an elegant solution for this, let’s see if you can find it!

There’s a clue on my github repo: https://github.com/dmerejkowsky/dotfiles/branches

Answer on my blog soon.

PS: No spoil, please

Well, it’s time for me to give the answer.

z is a tool that will remember all the directories you are visiting when using your terminal, and then make it possible to jump around those directories quickly.

Let’s try and rewrite this functionality from scratch, maybe we’ll learn a few things this way.

Last month, I heard about fzf for the first time.

Today, it has become one of my favorite tools and I can no longer imagine working on a computer without it installed.

Let me tell you what happened.

TL;DR: Annotations in Python3 are very useful when declaring interfaces using abc metaclass.

If you want to stop reading here, I’m not going to stop you:)

If not, allow me to take you to on a small journey where I explain what all of this is about …
