The field of data engineering is evolving quickly. This article describes three major trends I see become prominent in the coming years. The role of a data engineer was almost nonexistent ten years ago. But, the need for this particular kind of software engineer has grown. As the field got more mature, the role evolved. The responsibilities of a data engineer vary from one company to another and the role does not evolve at the same pace everywhere. [Read More]
Supply Chain Security Python
TL;DR A new kind of cyber threat has come to light recently: software supply chain attacks. While rare, they have massive impacts, and protecting against them is a rising concern.

It’s easy to feel overwhelmed by the number of things you have to learn. Job descriptions are intimidating and you might end up with this feeling that you are not ready, that there is still so much to learn. [Read More]
5 Advanced Pytest Tricks
We write tests because they help us build confidence in our code. They also help us write clean and maintainable code. Yet, writing tests requires some effort. Fortunately, there are libraries we can leverage. Pytest, for example, comes with a lot of handy features that are often not used. In this article, I will introduce you to 5 of them. Test logging with caplog fixture Sometimes, logging is part of your function and you want to make sure the correct message is logged with the expected logging level. [Read More]
How to write a TCP scanner in Go
In the toolbox of any pen tester, there is an app that allows them to detect open ports on a given server. Thanks to such an app, they can list all network entry points available on the system. These entry points can be open doors for attackers and this is why they need to identify them early in the process. The most famous TCP port scanner is a tool called nmap. [Read More]
Learning Go, first impressions
Over the past couple of weeks, I have been interested in Go. I have been developing mostly in Java and Python for 3 years now and I was keen to learn a new language. As I was looking for a new language to learn, Go caught my attention. Indeed, this language created by Googlers in 2007 has a lot of traction, especially with the rise of cloud-native apps and projects like Kubernetes or CockroachDB that are essentially developed in Go.

K8s security - part 0 - Security Model
Prerequisite You already know Kubernetes architecture, its components and have notions of cybersecurity. Abstract In this introduction of a series devoted to Kubernetes security, we will first see that Kubernetes, although very popular and used by thousands of companies, is very hard to completely protect from attacks espescially if you create and operate your own cluster. Vulnerabilities have been discovered in the past and have sometimes been exploited by attackers. We will explore what makes Kubernetes hard to secure by default and propose a model that represents the layers that need to be secured. [Read More]
