Le Dark Mode (mode d'affichage sombre) est aujourd'hui largement plébiscité, que ce soit sur mobile ou sur écran de bureau, mais concrètement quelles sont les meilleures techniques pour proposer des thèmes de couleur à nos visiteurs ? Dans cette présentation, nous parlerons de modes d'apparence, de couleurs système, de @prefers-color-scheme, de color-scheme, de light-dark() et de @prefers-contrast.
DevOps.NET
.NET Aspire is the brand new framework from Microsoft for opinionated observability and deployment in the cloud. Come see how the pieces fit together, how to upgrade an existing site, and the benefits of OpenTelemetry. You can add as much or as little .NET Aspire to your app, and even use it only in dev.
Cloud Computing
The biggest pain point of moving to the Cloud is… Nope! Not security! It is cost control!
Many organizations fail at this because they have a reactive approach (analyzing invoices at the end of the month and paying the bill) rather than a proactive one (performing predictive analysis and cost estimates continuously).
In this talk, I will show you 10 strategies. You will be surprised to know that they are not all technical.

Architecture & Design Patterns
Let’s dive into the controversial side of tech trends, as not all trends benefit developers. We’ll discuss how some might be misleading despite their prevalence in the industry. Our goal here is to spark meaningful debates and challenge conventional wisdom.
JavaScriptTests & Quality
Refactoring code without tests is risky. But to write tests, you often need to refactor the code first. How do you deal with that paradox?
I will show how to reduce the risk, even when missing tests. We will focus on refactorings I’ve found particularly useful when dealing with legacy codebases. You may know some names but probably don’t know the proper moves. Let me teach you how I do it.
Examples will be in TypeScript.

Architecture & Design Patterns
Changeset evolution is a concept that originated in the Mercurial version control system and has slowly been adapted to git. When working and reviewing a series of commits, it can be helpful to be able to change each individual commit in the series, without adding new commits on top. This produces cleaner history and eases the burden of reviewers during the backs-and-forths of the review process. We'll look at Jujutsu and git range-diff.
DatabasesJava & JVM languages
See a demonstration of how developers can quickly build microservices with Micronaut and GraalVM Native Image.

Tests & QualityPython
Mock objects are a great trick for testing code that cannot be tested any other way. Unfortunately, a lot of developers have interpreted that to mean that mock objects should be used for testing any and all code. This leads to tests that are not very thorough, tightly coupled to the code under test, hard to understand, and hard to modify. I'll discuss some techniques that help you write better tests -- most importantly, fakes and stubs.
