Deuxième volet de notre série EDA : l'article à la fois chiant et utile. On rentre dans la théorie — patterns (Pub/Sub, Event Sourcing, CQRS), garanties de livraison, gestion des ratés (replay, DLQ) et pièges classiques. Promis, on a essayé de rendre ça digeste.

L’IA agit comme un multiplicateur de vitesse sur les systèmes existants. Elle n’améliore pas mécaniquement les organisations : elle accélère leurs dynamiques, qu’elles soient robustes ou désalignées. Cette accélération révèle les fragilités de l’ingénierie, du produit, du SI et de l’organisation. Le véritable enjeu n’est pas l’adoption de l’IA, mai
On parle souvent de dette technique, de code illisible, de tests manquants. Ces diagnostics sont justes, mais partiels. Ce qui se dégrade en premier dans un système legacy, ce n'est pas le code. C'est la mémoire collective de ceux qui l'ont construit. Et sans elle, même un système propre reste difficile à faire évoluer.

This was originally written and published by Christophe Spy (Director of Engineering, Medium) as an internal Medium Eng post. Desired outcomes (what “good” looks like) 🙏🏻 These are the kinds of changes we want to see if AI is going well at Medium. Less drudgery, more leverage Engineers use AI to remove repetitive, low‑leverage work (e.g. tedious refactors, boilerplate, large…
Authors: Auriane Bonmarchand , Carolina Tealdo & Minh-Quyên NGUYEN In our previous post , we explained the Engineering Program Manager role at Criteo at a high level: EPMs sit at the intersection of business ambition, technical reality, and execution, helping complex cross-team initiatives move from intent to delivery. But if you are considering this role, that high-level description is only…

Author: Diana Cibu Public orators have played a major role in spreading knowledge and driving progress since the early days of oratory in Ancient Greece. I’ve always been fascinated by speakers’ unique ability to catch an entire audience’s attention and how they turn messages into valuable takeaways that stick with you long after their speech is done. If there’s one…

Stop Defaulting to "use client": A Practical Mental Model for React Server Component Architecture
JobTeaserHow thinking in server-first component boundaries can simplify data flow and reduce client JavaScript in Next.js applications. When I first started working with the Next.js App Router, I kept running into the same situation. Components would suddenly break — usually after adding a hook or a click handler. The fix felt obvious: add "use client". But after doing this a…

Excerpt In complex, long-running agentic systems, maintaining alignment and coherent reasoning between agents requires careful design. In this second article of our series, we explore these challenges and the mechanisms we built to keep teams of agents working productively over long time spans. We present a range of complementary techniques that balance the conflicting requirements…

Expedia Group Technology — Engineering A lightweight framework for balancing speed today with agility tomorrow Photo by Benjamín Gremler on Unsplash As engineers, we’re often encouraged to “move fast” — and for good reason. Delivering value quickly is critical. But running fast usually means taking shortcuts: skipping tests, hardcoding a value, bending an abstraction a bit too far. Individually, these…

How we made our filtering 10x cheaper by removing our Bloom Filters Bloom Filters are great tools to make fast and cheap filtering. They also come with plenty of problems and can easily get expensive and cumbersome. We switched to user-based direct database queries, which made our filtering cheaper and easy to maintain. Here’s the full breakdown of that migration.…

The Jobteaser application contains a lot of different relatively independent modules to help universities provide career guidance to students: a job board, a career event management system, a career advice appointment management system… When we decided to migrate our application’s backend from a monolith to a service-oriented architecture, we strived to keep each module as isolated as possible from the…

When it comes to the communication between microservices, there are 2 possible extremes: All-sync: whenever a service needs data from another service, it fetches it via a synchronous API call (REST, gRPC, GraphQL). Service calls service calls service… which tends to evolve into layers of APIs, where each layer has dependencies on the next. All-async: no sync calls between services,…

To Build (an SDK), or not to Build — that is the question! If you are building a SaaS product, you most likely also provide an API for your product.

Software engineering, knowledge work, or most broadly any type of white collar labor is, primarily, the production of our own psychology. Our mental capacity is our means of production. We embody the values of our work. Our identity is tightly bound up with our careers, knowledge, skills, methods, company, and our industry—we are our work. Having our identities bound to…

Application logs are useful for many reasons. They are the primary source of troubleshooting information. Logs are essential to forensics during any rigorous security analysis. Web server logs are often used for analysis in order to gain insight into usage, audience, and trends. Logging Logs are time-ordered streams: there is no beginning or end, but rather an ongoing, collated collection…
Not too long ago, there was a great debate between two sides of the web. The “Responsive” web vs the “m.” web. One pushing for a single codebase that responds to user-context and another pushing for a second, mobile-only approach (typically using a subdomain starting with m.) It’s clear now, the responsive web has won. A Retrospective — Responsive Design…
