Avez vous déjà écrit un code supplémentaire pour recouvrir un besoin future “au cas où” 🤓?

L’over-engineering, est une pratique consistant à développer des solutions excessivement complexes et sophistiquées et qui ne répondent pas forcement aux besoins de l’utilisateur.

Dans le domaine du logiciel, cela se traduit par une focalisation excessive sur la qualité au détriment de la rapidité 🚀.

La sur-ingénierie coûte généralement très cher à l’entreprise :

💸 une augmentation des coûts
⌛ des délais de développement prolongés
🤯 une complexité accrue du système

Pour éviter ce piège ☠️, des exemples et des astuces sont à découvrir dans cette conférence 😉.

Video games are not limited to what the vast majority of people define it to be. Especially as a game developer in a third world country where a lot of development is out sourced. Had the chance to work on so many video games made for purposes other than Entertainment. All kind of serious games in health, education, training and more. Advergames to advertise products and brands and other. I’ll explain to you how I had to go through all of this, before having the opportunity to work on games built for the sake of having fun.

Pendant 3 ans, j’ai exercé en tant qu’UX/UI designer freelance, une aventure pleine de défis cachés et d’enseignements précieux. Dans cette intervention, je partage mon expérience personnelle et les outils qui m’ont aidée à surmonter les obstacles du quotidien : de la gestion des projets à la communication avec les clients, en passant par l’organisation de mon travail. Je détaillerai notamment :

• Les difficultés souvent méconnues du freelancing et comment les aborder efficacement.
• Les outils indispensables pour structurer son activité et gagner en productivité.
• Les leçons que j’aurais aimé connaître dès le début de ma carrière indépendante.

Cette session s’adresse à tous ceux qui souhaitent optimiser leur pratique en freelance, qu’ils soient déjà en activité ou envisagent de se lancer.

In this talk, we’ll explore building full-stack web applications powered by Astro, Astro Actions and Astro DB. We’ll start by discovering the basics of Astro, why and where it’s useful, and how to build a web applications with it. We’ll discover how to use Astro’s new default hybrid rendering mode to add API routes and dynamic server-side rendering to the application. Then we’ll dive into Astro DB, a simple, yet powerful ORM used to communicate between a LibSQL database and your Astro application. Also, Astro 5.0 has been released, we’ll round up the talk by looking at how we can combine all of these features with a powerful headless CMS like React Bricks.

Losing my mother to scleroderma redefined my life. Leaving my corporate career to care for her, I built Koyotec while coding through the night. Now, driven by her memory, I return to university to master machine learning. My goal: a classification model for the early detection of scleroderma, helping medicine know at the early stage. I’m exploring various architectures, likely a hybrid approach leveraging both convolutional neural networks (CNNs) for image analysis of potential skin changes and recurrent neural networks (RNNs) to analyze time-series data from patient records. The model will be trained on a carefully curated dataset, focusing on feature engineering to maximize sensitivity and specificity. This is my legacy, transforming grief into a future of hope.

De nos jours, les navigateurs sont de plus en plus performants et peuvent gérer un volume croissant de données, mais ils ont tout de même leurs limites. Plus le nombre de nœuds dans le DOM augmente, plus il devient difficile pour le navigateur de tout gérer efficacement, ce qui peut rendre l’expérience utilisateur désastreuse.

Dans cette conférence, je vous conterai les aventures d’un développeur front tentant de démêler ces nœuds. À travers un retour d’expérience sur la problématique liée à l’affichage d’un grand volume de données, nous analyserons les solutions mises en place ainsi que leurs limites. (Spoiler: on va parler de virtual list)

Porting video games allows for the discovery of new technologies while having fun. Additionally, it’s an excellent entry point into the world of video game development. This is especially true thanks to WebAssembly, which simplifies the process of porting games to browsers.

During this session, I’ll share my experiences with my first porting project. I’ll explain why I chose to port Doom. Then, I’ll demonstrate, step by step, how I successfully integrated the browser Canvas and AudioContext in JavaScript to achieve rendering that can reach up to 60 fps.

By the end of this conference, you’ll see video game porting in a new light. So, if you’re passionate about video games or wish to explore how WASM contributes to game porting, this session is for you.

Cross-platform frameworks like React Native, Flutter, and Kotlin Multiplatform promise native-like experiences with shared codebases—but how do they actually achieve this? This talk dives into the core mechanisms behind these technologies, exploring how they bridge to native code, compile across platforms, and render UI efficiently. By understanding their inner workings, developers can make informed choices when selecting the right framework for their next project.

J’ai souvent rencontré les mêmes mauvaises pratiques qui transforment peu à peu une application en un véritable cauchemar : fuites de mémoire, requêtes SQL inefficaces, et code difficile à maintenir. dans mon talk, je partagerai avec vous ces erreurs courantes et vous montrerai comment les éviter pour ne pas finir avec une usine à gaz.

Today, in cloud-native projects, an observability stack is systematically in place. There are many such stacks (Elasticstack, Graylog, Grafana…). All those stacks, except for SaaS solutions like Datadog, rely on two solutions for log storage and search: Elasticsearch or Grafana Loki.

Both solutions have their pros and cons: on one hand, Elasticsearch is based on a very powerful search engine (Apache Lucene) but consumes a significant amount of resources to maintain performant indexes. It requires a primary node and replicas, with all data stored on block storage (SSD), which can become excessively expensive. On the other hand, Loki is very fast at ingestion and less costly because it stores logs on object storage but lacks the indexing power of Elasticsearch, making searches often slow and complex.

In this presentation, we’ll present Quickwit which combines the best of both worlds. We’ll explain how it achieves this by rewriting a search engine comparable to Lucene with high performance and leveraging the gains to store indexed data in object storage.

We’ll also see in this presentation that Quickwit can serve as a backend for storing traces via OpenTelemetry and is compatible with Jaeger UI, allowing traces to be stored durably over time.

This presentation will include a demo where Quickwit will ingest logs and traces from a Python application via OTLP/grpc. We’ll showcase dashboards with the Grafana plugin, enabling the correlation of logs and traces

React Native permet aujourd’hui de créer facilement des animations fluides et élégantes, améliorant l’expérience utilisateur et rendant les applications plus attractives. Dans cette conférence, nous explorerons plusieurs types d’animations simples à développer et à intégrer dans vos projets.

A talk exploring the world of 3D, animation, and computer-generated visual design. Attendees will gain insight into what 3D is, its diverse applications, and how it shapes industries. The session will also highlight various opportunities for monetizing 3D skills and turning creativity into income

Global payment systems are intended to connect us all, yet they often overlook the unique challenges faced by people in underserved economies. This talk dives into the creative ways Nigerians navigate and design payment solutions when major platforms fail to address local realities. For freelancers and entrepreneurs from Nigeria and other similar socioeconomic contexts, accessing international clients or services isn’t always straightforward. Traditional payment systems can be restrictive, making it difficult to send or receive funds, and global platforms often lack support for local currencies, banking structures, and reliable access.

I will share insights from my personal experience as a freelancer from Nigeria, covering both the challenges and the ingenious, often community-driven solutions Nigerians have developed to thrive financially. From mobile banking innovations and peer-to-peer transactions to informal digital networks, these strategies reflect a deep cultural and technological adaptability.

By examining how people work around these gaps, this talk will offer practical takeaways for designers and developers aiming to create more flexible and inclusive financial tools. Attendees will gain a deeper understanding of the resilience in these communities and learn how to incorporate similar adaptability, inclusivity, and human-centred thinking into global design solutions for payment systems.

Step into the intriguing world of hackers and uncover the techniques they use to access personal and sensitive information. Explore their methods, understand the risks and learn how to protect yourself in today’s digital landscape.

In more and more projects, we find ourselves needing libraries to share code and features, all while managing different framework versions. At CamelStudio, we encountered this need in one of our projects: developing a Java library compatible with both Java 17 and Java 8.

To address this challenge, we turned to multi-profile artifacts, a solution that allows us to build specific versions tailored to each target environment. Additionally, we set up a GitLab CI pipeline to test and easily generate these various artifacts.

In this talk, I’ll explain how multi-profile artifacts work and how to implement them.

Agenda:

• Introduction to Java artifacts
• Generating a library for Java 17
• Overview of classifiers and multi-profile artifacts
• Building the library with two profiles for compatibility with both Java 17 and Java 8
• Setting up GitLab CI for releasing, packaging, and versioning artifacts

When trying to refactor code, how many times have you traveled back in time unraveling mysteries, revisiting forgotten decisions, and questioning past logic just to make sense of it all? In this talk, we will explore why it matters to improve our code, when it’s time to refactor, best practices to follow, real-world cases , and much more
