A Step Toward Technology

Wed, 25 Feb 2026 13:00:00 +0100

Growing old in Europe is not just about “having more years.” It also means having to navigate a world where access to rights, healthcare, and social connections increasingly happens through screens.
Technology is no longer background scenery. It has become a daily life tool… but also a factor of exclusion when poorly designed.

I. An ageing society

In France and across Europe, around 22% of the population is aged 65 or over (estimate as of January 1, 2026).

DevOps Cycle or a Misunderstanding of the Role?

Tue, 24 Feb 2026 11:00:00 +0100

Introduction

The term DevOps is frequently used to describe a heterogeneous set of topics: CI/CD, cloud, Kubernetes, security, observability, incident management, cost management, and more. This breadth of meanings creates a recurring confusion: an organization expresses a need for “DevOps” without specifying the expected value, the associated responsibilities, or the target operating model.

The outcome is well known: a succession of urgent periods, followed by automation initiatives, and then a gradual return to the same difficulties. This is often described as the “DevOps cycle.” In many cases, this cycle is not intrinsic to DevOps itself, but rather the indicator of a misunderstanding of the role: DevOps is used as a compensating function (support, firefighting, implicit ownership of production) instead of as a structuring organizational capability.

Upgrading Your Computer Components: Method, Compatibility, Benchmarks… and Mistakes to Avoid

Upgrading Your Computer Components: Method, Compatibility, and Benchmarks

Upgrading your computer hardware often feels like a simple and logical process:
you identify what feels slow, buy a more powerful component, and install it.

In practice, many upgrades:

bring no noticeable performance gain,
introduce compatibility issues,
or simply move the problem elsewhere.

So how should you approach it properly?

AI, Code, and Design: Why the Most Important Thing Hasn’t Changed

Wed, 21 Jan 2026 10:00:00 +0100

I. Introduction

AI-powered coding assistants are now capable of producing:

syntactically valid code,
working code,
and even a certain form of reasoning about code structure.

Faced with this, a legitimate question arises:
do we still need to learn how to code, or is it enough to learn design and leave the rest to AI?

This question lies at the heart of a video titled “The Skill That Separates Good Developers from GREAT Ones” by Emily Bache, which offers a nuanced answer deeply rooted in the fundamentals of software engineering.

Developing with AI: What Changes, What Stays, and What Becomes Critical

Wed, 07 Jan 2026 10:00:00 +0100

I. Introduction

AI-powered coding assistants have profoundly changed developers’ day-to-day work.
They generate working code in seconds, propose complete implementations, and drastically reduce the time spent on repetitive tasks.

This evolution raises a central question:

If code can be produced easily, where does the developer’s value now lie?

To answer it, we must look not at what AI can do, but at what it does not take responsibility for.

“It’s slow”, “it lags”, “it bugs”: but in the end, what does it really mean?

Tue, 30 Dec 2025 10:00:00 +0100

Introduction

In a family, at work, or within a technical team, it is very common to hear: “it’s slow”, “it lags”, or “it bugs”. These expressions are often used interchangeably… wrongly. They mix together problems that actually have nothing to do with each other.

Understanding the difference between these three situations makes it possible to explain what is happening more clearly, to react more quickly, and above all to avoid bad solutions. A performance issue is not solved like a bug, and a bug never disappears just because the machine has been made more powerful.

Writing a Prompt: Technical Guide

Fri, 18 Apr 2025 11:02:00 +0100

I. Understanding What a Prompt Is in LangChain

In LangChain, a prompt is a textual structure designed to guide a language model. A well-constructed prompt includes several key components:

Instruction: What you explicitly ask the model to do.
Context: Additional information to frame the answer.
Input Data: The specific input provided at runtime.
Output Indicator: What kind of output is expected.

This format enables clear, framed, and reproducible queries.
Here’s another example using LangChain in Python with this structure:

Hallucinating with LangChain

Mon, 07 Apr 2025 09:22:00 +0100

I What is a hallucination?

A hallucination refers to a response generated by a language model that is factually incorrect, invented, or misinterprets reality. It can range from a minor inaccuracy to a completely fabricated citation or even a made-up technical or historical claim.

Example:

“Einstein discovered general relativity in 1975.”

That’s incorrect (it was in 1915), but the model might produce this kind of statement if it lacks the proper context or is too confident in its reasoning.

How to Count Tokens Effectively

Tue, 01 Apr 2025 17:52:00 +0100

I. What Is a Token?

A token is a unit of text that the model processes. It could be a full word, part of a word, or even a special character.

Concrete Examples

Text	Number of Tokens
Hello	1
I am a developer	4
Artificial intelligence is fascinating!	5
GPT is a powerful model.	6

Specifics of Tokenization

In English, short words are often 1 token (e.g., "Hello" = 1 token).
In French and other languages, longer words can be split into multiple tokens (e.g., "développeur" or "intelligence" = 2 tokens).
Punctuation also counts as tokens.
Spaces are included with the following word.
Acronyms are usually treated as 1 token.

On average, 100 tokens correspond to roughly 75 words, though this can vary depending on the language and writing style.

What is a Bundle? Understanding the Concept

Mon, 03 Feb 2025 10:00:00 +0100

The term “bundle” is widely used in web development and DevOps. It refers to a grouping of files, resources, or elements to simplify their management and improve performance.

However, a bundle does not have the same meaning everywhere. In this article, we will explore its different uses in three key areas:

Hugo (static site generator)
CSS & JavaScript (front-end development)
DevOps (Docker, Kubernetes, Helm, etc.)

1. Bundle in Hugo: Organizing Files Smartly

In Hugo, a bundle is a folder containing a page and its associated resources (images, JSON files, etc.). There are two types of Page Bundles:

A Brief History of AWS Architectures

Fri, 20 Dec 2024 09:56:41 +0100

I. The Early Days of AWS and Cloud Computing (2002 - 2006)

Context: The Origin of the AWS Project

Before AWS became a cloud giant, Amazon.com (the e-commerce site) had to manage a massive IT infrastructure to support its rapid growth. The company invested in expensive data centers and had to anticipate server capacity for peak traffic periods (such as Black Friday). However, much of this capacity remained unused outside of high-demand periods.
