This month I’ve learned about the Mikado method, a great way to work with legacy code safely.

Essentially, through some small iterative steps, you will be able to explore the legacy codebase and assess what should be done to add new functionality.

This approach could also be used during an Exploratory Refactoring; neat, eh?

During one engagement I had to work massively with certificates, keystores, PKIs, HSM, etc. and at that time I needed an introduction to all these concepts so I started looking around when I finally found this article. It is a very comprehensive article about PKIs, how the certificate’s world works and it’s worth a read once in your life to at least understand what’s going on under the hood of your browser and how certificates protect your privacy.

Learning a new language can be cumbersome for many reasons and looking for a way to do it efficiently I discovered that practising TDD helps me to do it, faster.

My colleague Marco Garogalo pointed me out to a website called TDD Buddy where you can find a nice katas collection that you can solve using TDD.

I decided to spend some time trying to learn Rust solving those katas, how is it going? I actually completed 2 katas with just the Rust doc and TDD. 🎉

Every time I have to refactor, it forces me to dig deeper into the Rust world, it forces me to use proper structures or rust functions.

I can literally see my understanding evolving over time, making small controlled changes to my codebase focusing only on what matters, safely.

Thank you for reading this issue ✨
