Top 20 My wish List
HTML & CSSUX & UI 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. Discover how combining GraalVM Native Image and Micronaut can lead to efficient, highly performant, and optimized applications targeting environments like Kubernetes or serverless platforms. Learn to access an Oracle Autonomous Database (ADB) using the Micronaut framework with Micronaut Data—and how to use Micronaut, AOT, and GraalVM
DevOps In this talk, we will discuss the most common ways software fails and some of the most unusual ways too. I will provide valuable lessons, tips, and advice so you can avoid the same mistakes, reduce the risks, or fail confidently. This talk is for anyone who has ever worked in production and/or responsible for deploying and maintaining software. If you have ever brought down production or are afraid of it, this talk talk is for you.
.NETMobile Learn how to streamline native feature interactions in cross-platform .NET applications. We'll explore how different OSes handle native user features, like iOS FaceID and Android Biometry, and how to decouple them for platform-agnostic functionality. Through a real-world example of managing Biometry APIs, you'll discover how to abstract development without compromising performance or user experience.
AccessibilityTests & Quality Accessibility is vital in web development. This session covers using Cypress and Axe Core for practical testing. Learn to set up these tools, integrate them into CI/CD, and address challenges. Through real examples, you’ll see how to detect and fix accessibility issues early. Attendees will leave with strategies to ensure their web applications meet standards and offer an inclusive user experience.
Architecture & Design PatternsUX & UI In this talk, we will be discussing strategies for integrating new design directions and design systems into existing, legacy products. We will deep dive into strategies such as defining your goals and setting a roadmap, working collaboratively with design teams, the importance of design systems, leveraging technical tools like feature flags and Storybook, and how to overcome technical debt and resistance to change.
Architecture & Design PatternsNetworks In this session, we'll dive into the complexities of error handling in event-driven architectures (EDA). We'll explore how to effectively detect and manage errors in asynchronous systems using choreographed sagas and dead-letter queues. You'll learn practical strategies to address common pitfalls, such as infinite loops and unmonitored DLQs, ensuring your system remains robust and resilient.
Tests & QualityArtificial Intelligence Integrating AI into your application transforms the traditional software development and DevOps lifecycle. Unlike standard code, LLM outputs can vary for the same input, leading to different accuracy levels. This affects both pre-deployment testing and post-deployment monitoring. To achieve and maintain quality, you will learn to apply ML/LLM Ops practices from data science within your software development and DevOps lifecycles.
Artificial IntelligencePython Learn about advanced profanity detection patterns beyond simple keyword search. My session will cover data collection and training of a profanity detection model, and it's integration with live Speech-to-Text AI technologies. We will also look at the challenges around handling live data.
Architecture & Design PatternsPHP Working with APIs? Great! Did you have to solve surprisingly similar issues in different projects? Did project complexity force you to break the established guidelines for structure, filtering, validation, or pagination? How often have your endpoints, versioning, and evolution stood the test of time? Let's talk about the real examples of solutions I implemented in various APIs. Smile at changing requirements thinking - I've got it!
PHP API Platform est un framework permettant de créer très facilement des API REST (hypermedia) et GraphQL très populaire dans l'écosystème Symfony.

Depuis sa version 4, API Platform est également compatible avec Laravel.

Simplicité d'utilisation, respect des standards, documentation d'API automatique extensibilité, support aisé de pattern comme CQRS ou du DDD tactique, API asynchrone...

Faisons un tour d'horizon du framework.
DevOpsJava & JVM languages Do you regularly spend your nights trying to make sense of cryptic error messages? In this example-driven presentation we go through more advanced topics of Observability, and dive into the toolsets available to you to instrument your JVM-based app so that it can tell you what it is doing and why. We will explore how to instrument apps without vendor lock-in using Micrometer, OpenTelemetry, Grafana, OpenZipkin, Prometheus, OpenMetrics, etc.
Architecture & Design Patterns Avez-vous déjà demandé à un architecte: Quel est la meilleure architecture? Ou Quel est la meilleure technologie (storage, hosting, framework, ...)?

Est-ce que vous avez eu la réponse classique: "Ça dépend"?

Dans cette présentation je vous présenterai les outils qui vous permettrons de prendre de bonnes *décisions* sur des *faits* pour solutionner de *réels* problèmes à l'aide de solutions *adaptées* selon les *contraintes*.
Tests & QualitySecurity Do you use JWT access tokens to secure your web API? If you are, are you absolutely certain that your API only accepts access tokens issued by your service?

In this session, I’ll expose some shocking tricks that can bypass improperly configured token validation. You’ll see how easy it can be to fool your API. But don’t worry, I’ll also walk you through how to write tests that ensure your application is protected against these exploits.
Cloud Computing.NET As developers we know what our application needs from the cloud, so we should be the ones creating the cloud infrastructure for the app. Pulumi is an IaC tool that lets you use general purpose coding languages like C#, TypeScript, and others. So in this session we'll look at how to use C# and Pulumi together for writing Infrastructure as Code to create Azure services and then deploy our apps to it.
HTML & CSSJavaScript We've strayed too far from the simplicity and power of HTML forms. It’s time to undo the damage. Once relegated to basic data collection, forms offer a surprising depth of functionality that's being rediscovered by developers and embraced by modern frameworks like Astro, Fresh, Remix, and Next.js.

Let’s rediscover the power of HTML forms and how they should be leveraged in modern web application development.
PHP In this talk I explain how to use Xdebug to get more productive writing PHP code, focussing on the improvements in Xdebug 3.2 and 3.3, and the upcoming 3.4, to make the debugging experience better and easier to set up.

Beyond that, this session also goes through a few complicated scenarios that are harder to debug, and shows solutions to these conundrums. I will also focus on the new features, such as native path mapping.
HTML & CSSJavaScript If your head has spun in the last few years trying to keep up with the latest evolutions of HTML and CSS, you’re not alone. In this talk, we'll dive into the latest HTML and CSS features that are reshaping UI development. Learn how these features are reducing our reliance on JavaScript in the 'front' of the frontend and moving some accessibility concerns, dynamic positioning, robust animations and more to the browser.
Architecture & Design Patterns Systems grow and change over time. You can have intentional design, or accidental design.

In this session we will walk through approaches that leverage product context to keep architecture aligned with the needs of the product. We will look at strategic DDD, C4 modeling, and architecture decision records.

Leave this session with simple techniques that you can apply immediately to start blending product with architecture.
MobileUX & UI Want to take your mobile app to the next level? We'll explore the small but powerful details that elevate apps from good to great. Through real-world examples and code, we'll cover animations, gestures, native APIs, seamless keyboard interactions, and frictionless authentication flows. Whether you're after quick wins or advanced techniques, this session will give you practical tips to enhance your app’s user experience.

PHPUX & UI PHP is traditionally known as a server-side language. But what if you could use PHP to build desktop applications that run on Windows, Linux, and macOS?

This talk will delve into two different solutions to create true cross-platform, desktop apps with PHP. We'll explore NativePHP, a tool that allows developers to build desktop apps using PHP and Electron and show how to integrate WebView directly with PHP using FFI or a custom extension.
Artificial Intelligence In this session, we will explore the process of building single-purpose micro-agents and orchestrating them to form a versatile super agent. This approach leverages the strengths of each micro-agent, which possess their own planning, reflection, and self-critique capabilities, to collectively tackle complex tasks.
HTML & CSSUX & UI Depuis que Flash est mort, CSS et JavaScript reprennent peu à peu le flambeau des animations sur le Web.
Cependant, ces dernières années ont connu de formidables progrès et il est aujourd'hui possible de réaliser des animations CSS à la fois simples, performantes et variées (suivre des tracés, déclencher des animations lors du scroll ou de l'apparition dans la fenêtre, au changement de page, etc.) !
AccessibilityArtificial Intelligence Accessibility is more than just a checklist—it's a web fundamental. However, incorporating AI tools like GitHub Copilot into your workflow presents both new possibilities and unique challenges. In this case study, I’ll share my experience using GitHub Copilot to build accessible web components for Adobe Express.

Startup Whether you're a freelancer or managing a small agency, growing a business in the web industry can be challenging. The lull between projects often tempts many to hastily onboard any potential client that comes your way. One of the biggest mistakes that you can make is to take on just anyone as a client during these discouraging times. This session will uncover effective strategies to filter clients, boost your confidence, and charge more.
Cloud ComputingSecurity Cloud providers have shifted some security concepts out of coding into configuring cloud infrastructure. This makes cloud security an endeavor now worthier of investing time in.

While there are common secure patterns and mechanisms, some provider specifics are what can causes issues.

This session will present a selection of the most security friendly cloud architecture patterns, with highlights on quirks that hinders security.
Artificial Intelligence This talk explores AI's impact on software development, focusing on productivity enhancement.

Containerization helps, but gets you only part of the way there. So we'll dive into tools & techniques to deploy new installations, updates and software releases in a consistent way, showing even thousands of machines can be kept up-to-date by using the right architecture and flow.
DevOpsHuman Intelligence Development has become more complex. Building and running a distributed architecture, ensuring observability, and balancing speed and quality aren’t easy. Just being agile and practicing DevOps to increase productivity doesn't really solve the problem.

Learn how great teams measure and improve the developer experience and create a healthy and joyful engineering culture. Don't focus on productivity; focus on what makes this craft fun for devs.
Tests & QualityUX & UI I am an even-tempered person. But when I use poorly designed software or painfully slow apps, I turn into a monstrous beast. Authenticate AGAIN? I can’t find ANYTHING! ANOTHER ERROR!

Users today are massively frustrated by the sites and apps. They are furious when they can’t quickly do what they want. Yes, they blame us. How do we make products that help users easily accomplish their goals? How do we rage-proof our work? I’ll show you. how.
SecurityUX & UI Most people struggle to access digital products. Basic tasks like sign-up, login, and password recovery frustrate and enrage users. People constantly fail at them. More security can make it harder for people to use our products. We must keep bad actors out, but we also want approachable products. And dev teams struggle with user experience. Teams can lessen user pain and help people get beyond the access barrier. I'll show you how to start.
Java & JVM languagesPerformance Profilers are great tools in your toolbox, like debuggers, when solving problems with your Java application. I'll tell you some of their problems and a technique to cope with them in this talk.

There are many open-source profilers for Java, but they all have problems, I'll show you which and how to deal with them in this talk.
AccessibilityHTML & CSS If you've been building websites for a while you "know" that some things require JS and that's just the way it is. Turns out, spec writers and browser makers both are working hard to find common JS patterns and implementing them in CSS and HTML. Things like accordions, auto-suggest, smooth scrolling, dialogs are all available without JS.

In this talk I walk through common patterns and explain how they can be implemented in CSS and HTML.
JavaScript Yes, you can run multiple threads in JavaScript, using worker threads! This talk will first of all explain how JavaScript feels multi-threaded, but is actually single-threaded. It will discuss in which cases this is a problem, and then delve into the main course: worker threads and how they solve the problem of multiple threads. It will also discuss how to communicate between the threads using atomics, shared memory, and other constructs.
.NETPerformance I ported the game DooM from C to C#. Having to deal with strange file types, alternative ways of (re)allocating memory, data structures being passed around as void* pointers and the likes, it's tempting to use unsafe code in C#. Turns out, that's not needed!

Let's look at how C translates to C#, and how C# adds safeguards to avoid shooting yourself in the foot. Or learn how taking on a crazy project like this can make you a better developer.
Java & JVM languagesTests & Quality Having problems creating a maintainable set of integration tests for your enterprise Java application? With the Testcontainers project, convoluted and complicated integration tests can be a thing of the past!

Artificial Intelligence This session covers how embedding models can retrieve relevant method matches more effectively than traditional search. We’ll explore real-world examples, like migrating identity providers, where we can use embeddings to identify all HTTP authorization headers across libraries. Additionally, we’ll cover how the top-k selection technique improves search speed and accuracy, by leveraging code-as-data models which use Lossless Semantic Trees.
Python Python "batteries included" comes with powerful loop constructs, but knowing how to use them correctly can be tricky. This talk introduces the itertools module, which offers functions designed to make your loops smarter rather than harder.

We'll explore a variety of itertools functions with real-world examples.

By the end of this presentation, you will have a set of itertools functions to create more efficient and powerful loops in Python.
PHPHuman Intelligence Naming is a central issue in computer science. To make code more understandable, a simple solution emerges from the collaboration of domain experts and the source code itself: a dictionary. By leveraging techniques from the linguistics of invented languages, this vocabulary becomes a foundation for constructing words, phrases, and eventually an entire literature. In essence, it entails creating a language specific to the code.
.NETPerformance Entity Framework makes data access in .NET applications as easy as defining some classes, adding a connection string, and writing some LINQ statements. Behind the simple facade, Entity Framework gives us multiple options for tuning our data access and improving performance. In this talk, you will learn how to tune EF Core for better performance and when to avoid it entirely!
JavaScript Native ESM support for Node.js was a chance for the Node.js project to release official support for enhancing the module loading experience, to enable use cases such as on the fly transpilation, module stubbing, support for loading modules from HTTP, and monitoring.

We will look at the architecture of ESM loading in Node.js, and discuss the loader API that supports enhancing it. We will also look into advanced features
Artificial IntelligenceHuman Intelligence Let's think a bit deeper and beyond the scandals with Cambridge Analytica, Facebook, VW- and see how our responsibilities go far beyond just delivering quality software adhering to requirements.

Moral implications, hard choices, ethical dilemmas with the blurred line between right and wrong - I'll share examples and try to make you think of what we can do in practice for leading an ethical professional life having a positive impact to society.
Architecture & Design PatternsPHP Let's take a deep dive in the world of event sourcing, projections and queues and see how a real world app ties these (and much more) together in a Symfony based app that links hundreds of (sometimes online, sometimes offline) computers spread over as many locations together. Not for the faint of heart !
DatabasesPerformance The optimizer is the "brain" of the database, interpreting SQL queries and determining the fastest method of execution. This talk uses the explain command to show how the optimizer interprets queries and determines optimal execution. The talk will assist developers and administrators in understanding how Postgres optimally executes their queries and what steps they can take to understand and perhaps improve its behavior.
Artificial Intelligence Learn about advanced techniques in retrieval-augmented generation (RAG) going beyond simple vector databases. LLMs need guidance!

Let me show you how the simple idea of coding "front-to-back" can reduce complexity, increase security, and help keep your codebase performant and maintainable
DevOpsStartup I will present a case study on implementing low or no-cost solutions for metrics, observability, and logging. Developers will learn how to leverage open-source and cost-effective tools to maintain visibility into their systems, improve debugging, and ensure reliable performance while minimizing costs.
Architecture & Design PatternsJavaScript You may be missing out on what your type system can do for you. And I don’t mean learning TS shenanigans!

I will show you how you can use types to represent your domain in a fine-grained, self-documenting way. We will make impossible states unrepresentable. We will encode business rules without writing a single line of runtime code!

With real-world examples, let’s dig into a more functional approach to modeling your app—without any monad!
Architecture & Design PatternsPHP Everyone and their dog knows and uses object oriented programming. While OOP is very useful, we pretty often focus on getting elaborate class hierarchies, intertwined with inheritance, frameworks, DI, libraries... What if I told you, that lots of these abstractions can be simplified with... plain functions? We won't even need to talk about Functional Programming, just functions! Let's solve a problem by not having it in the first place!
Human Intelligence De nombreux professionnels se retrouvent face à un dilemme : doivent-ils approfondir leur expertise technique ou passer à des rôles de leadership ? Cette session se penche sur la manière dont les développeurs peuvent trouver du sens dans leur carrière, qu'ils aspirent à diriger des équipes ou à rester dans le technique. À travers un atelier introspectif, ils apprendront à élargir leur zone de confort et s’épanouir pleinement, sans FOMO.

In this talk, we’ll explore what GraphQL is, how it works, and how to build GraphQL applications.
This presentation talks about the serious infrastructure cost minimization, the measurable and significant carbon-emission reductions by discussing real use cases of Greenification projects at CGI globally. It will demo examples of Green-Coding and Green IT modernizations, discuss some practical solutions and the proposals of Green Certifications for the Tech industry (similar to EnergyGuide / EnergyStar).
DevOpsSecurity Manage risks associated with your software dependencies through software supply chain security best practices and their automation across all SDLC phases. The growing ecosystem of tools such as in-toto, cosign, guac and grafeas allows us to envision a future where these threats can be addressed by organizations, regardless of their size and means.
We will demonstrate an end-to-end solution using such tools.
.NETPerformance The .NET Garbage Collector (GC) is great. It gives our applications the illusion of having unlimited memory, so we can focus on writing code instead of manually freeing up memory. But how does .NET manage that memory? What are hidden allocations? Are strings evil? What are generations? Frozen and pinned objects? HELP!!

In this talk, we’ll go over the base concepts of .NET memory management.
JavaScript If you want to write custom eslint rules, babel plugins, or other code parsers, you need to use Abstract Syntax Trees (AST). But they are generally scary for developers due to their complexity. In this talk, we will go through a real situation to parse some typescript React code using an AST and the Typescript Compiler API.
.NET Really, I don't know how to write React! I do know server-side ASP.NET Core, HTML and JavaScript. Which is all you'll need to build rich front-ends that feel like they are running client-side. Welcome, HTMX!

You can learn the basics of HTMX within a few minutes, and start using its rich collection of features to build any UI experience - usually a few HTML attributes are enough. In this session, we'll look at how you can get started with both.
PHP My PHP journey started with frustration and doubt. From outdated hosts to clunky frameworks, I questioned my skills. But with Composer, Symfony, and PHP's evolution over the last 15 years, I've overcome these challenges and now proudly embrace PHP as a powerful tool. As PHP got better, I did too: PHP 8 is great, the ecosystem is healthy, no reason to be ashamed anymore :)
Security Un grand modèle de langage (en abrégé LLM) est un type de programme d'intelligence artificielle (IA) capable de reconnaître et de générer du texte.

We’ll examine state-of-the-art object detection techniques like RT-DET and foundational models like SAM2, and explain the concept of grounding. Participants will gain insights into the latest trends.
Tests & QualitySecurity Discover how CodeQL, a powerful static analysis engine, can scan your codebase for vulnerabilities. Learn how to integrate CodeQL into your CI pipeline for automated security checks. We'll compare CodeQL to Semgrep and LLM-based engines, highlighting strengths and weaknesses. Get hands-on experience with CodeQL and take away best practices for implementing it in your development workflow. Improve your code security and reduce risk with CodeQL.
Java & JVM languages Attention: If you love to maintain legacy code than this session is not for you.
You probably know the hassle of maintaining code that was written long time before you entered the project or company. Often the developers who wrote it are not even in the company anymore. So how do you know if the code is still used? This session will give you an idea about what you can do to get rid of dead code.
Imagine being able to create extensible software allowing plugins to be written in nearly any language to execute arbitratry, untrusted code in a safe way. This is now possible thanks to Wasm and the Extism project.

In this talk, we'll write a Wasm plugin with Extism in Javacript, Rust and Go and demonstrate how to effortlessly integrate it into an application written in JavaScript, Python, PHP, Go, Ruby, ... in just a few lines of code!
PHPEcommerce Sylius 2.0 is already with us! This e-commerce framework based on Symfony has already been on the market for a while, and recently it reached a huge new milestone. As a long-time Core Team member, I will present the biggest changes and opportunities this new release brings, for both PHP and Symfony developers interested in E-commerce.
.NET On November 12, 2024 .NET 9 was released. As a part of this new version with 1.5 years of support, the web frameworks ASP.NET Core and Blazor were updated. This session will showcase the major new features that were added, including many live demos. Especially when currently using .NET 8, an upgrade to .NET 9 is optional due to the shorter support window, so you should know whether the new possibilities are worth the migration.
PHP During this presentation, we are going to look at the new features that are going to be introduced in PHP 8.4. Join me to have a look at Property Hooks, Asynchronous Visibility, Improved HTML5 parsing, and many other features.

At the end you will have a good understanding about all the new and exciting features that are part of the PHP 8.4 release
.NET Among the challenges developers face are naming things, cache invalidation, and off-by-one errors. But the one we never talk about is date logic! Date logic is full of fallacies and challenges that we as developers often hand-wave away, only to be bitten later! In this talk, we will explore and explain some of the common fallacies and challenges, such as daylight savings, non-standard timezones, and the challenge of presenting back to the user.
JavaScript We've all got Javascript fatigue. There are new libraries, frameworks, meta-frameworks and even runtimes. Against this backdrop of constant churn is the unlikely hero we all need - HTMX. At the outset, this library looks like a practical joke. But HTMX is a well-thought-out library. We'll understand the basics such as triggers, targets, swaps and indicators. We'll even build highly interactive applications using animations and Server-Sent Events.
Tests & QualityArtificial Intelligence I want to show you the secret weapon I have used for the past year. The GitHub Copilot lets me write full tests quickly, fills the gaps in my knowledge of 3rd party tools, and even writes clear descriptive commit messages. But it is not a "press the button to do it all". You need to guide the AI to do the right thing, which takes experience, but most importantly, you need to decide _what_ you want the AI to do, step by step. Remember: AI is
.NETMobile XAML is great for WinUI-based cross-platform apps… but it’s so hard to debug. In this talk, we’ll look at how to walk around these difficulties by leveraging C# for Markup, and how to use it to translate complex XAML into easily debuggable C# code.
Internet of Things I will introduce the current state of privacy in smart home products, exploring how many devices rely on cloud services that collect and share user data. The presentation will focus on Home Assistant, a local-first, open-source platform that allows you to automate and control your smart home while keeping your data private. Beginners will learn how to build a privacy-focused smart home without compromising on convenience or functionality.
Architecture & Design PatternsCloud Computing Set sail with us as we navigate the complex waters of migrating a critical task queue system, all without causing a single ripple of downtime. This session will explore the reasons why we switched systems, and the strategic use of feature flags and robust observability in ensuring a seamless transition. We share our lessons learned so that you can gain insights that can guide your own system migrations.
