Welcome to my "new" blog! I plan to publish articles related to Python, as you’ve probably guessed 🙂 I will cover topics like data science, programming, data, and other things (perhaps a bit less related to Python, but still within the Tech realm).
My posting schedule may be a bit slow, but please be patient!
Common Git mistakes
Do we really need to introduce Git!? It has become the essential version control tool for us developers. When I started as a developer, I used CVS... Arf, not all good memories unfortunately, the swit...
Data formats that survived every trend
In computing, we love new things! I have to admit, sometimes it is a bit excessive ^^ From time to time, we get a new format promising to be simpler, faster, more compact, or more flexible than the pr...
Why does caching create so many bugs?
When trying to optimize an application's performance, one of the first things we think about is setting up a cache. However, it is also an endless source of bugs that are often difficult to reproduce....
The pitfalls of UTF-8 encoding and Unicode
Since my beginnings in the early 2000s, I have hit several encoding problems. In fact, these are the kinds of bugs that can drive a developer crazy! An application works perfectly for months, then a s...
Why do developers spend so much time reading code?
People who aren't familiar with software development often imagine a developer as someone who writes code. They picture someone opening an editor, typing a few lines, running the program, and repeatin...
The languages that promised to replace JavaScript
Since its creation in 1995, JavaScript has often been seen by some as a transitional solution, and several languages have since been presented as possible successors. Several decades later, JavaScript...
How to learn Python quickly: A beginner's guide
Python has been popular for many years. Its simple syntax, versatility, and huge community make it an excellent choice for getting started with programming. Whether you want to build web applications,...
JSONL explained: what it is and when to use it
There's no need to introduce JSON (JavaScript Object Notation) anymore. It has become the de facto standard for exchanging structured data between applications. However, when working with large datase...
VPN: Do you really need one to protect yourself?
Whenever we browse the Internet, we expose our personal data to certain risks. A VPN (Virtual Private Network) is supposed to act as a "digital" shield by hiding our IP address and securing our connec...
Managing technical debt
Technical debt is probably one of developers' biggest concerns (it's my personal pet peeve). It creeps in over time throughout a project: a shortcut taken to meet a deadline, tests postponed until lat...
Common SQL database mistakes
SQL databases are predominant in professional applications, even though NoSQL databases have gained popularity in recent years for some specific use cases. They allow data to be stored, organized, and...
Why do developers spend so much time debugging?
Debugging is part of our everyday life as developers. Even when a project is well designed, tested, and documented, there always comes a time when something does not work as expected. Sometimes, a bug...
Signs that a project is becoming difficult to maintain
At the beginning of a project, everything seems simple. The code is recent, the features are still limited and well organized, and each change seems quick to implement. Then, over the months or years,...
Bugs related to race conditions
Race conditions are among the most frustrating bugs to fix for a developer. The problem is simple to understand: several operations can execute in parallel or be interleaved, and the result depends on...
What makes an API pleasant for developers to use?
An API can be technically correct while still being frustrating to use. Two APIs can offer almost exactly the same features, but we generally prefer the one that is easier to understand, test, integra...
What developers need from cloud ecosystems
Developers are increasingly relying on cloud ecosystems instead of traditional infrastructure. Applications must support users across multiple environments, integrate with a wide range of services, an...

Artificial Intelligence: The next technological revolution after the Internet?
The creation of the Internet at the end of the last century revolutionized our lives (for better or worse, depending on one's perspective…). But it didn't happen overnight; it took decades to profoundly transform our societies after its invention. Artificial intelligence seems to be following a similar trajectory. Often overestimated in the short term—just look […]

Essential Python libraries for Data Science
When you're a developer looking to dive into data science, you immediately think of Python ^^ (Okay, maybe I'm a bit biased haha). It’s fair to say that Python remains the undisputed star of the field, with a massive and rich ecosystem!In this article, we’ll take a tour of the must-know Python libraries, organized by […]
