In 2016, snapshot testing felt revolutionary. I promoted it everywhere. Then came the backlash: fragile tests, large snapshots, and mindless change approval. The community wasn't amazed. Yet in 2024, Node.js added native snapshot support. Why? This talk traces snapshot testing's turbulent decade: from Facebook's game-changing release to general rejection, and examines what place snapshots have today. Spoiler: the story isn't as simple as “snapshots bad”. Let's revisit with clearer eyes.

Check out Linear. — As software engineers, what should we know about writing secure code? Johannes Dahse is the VP of Code Security at Sonar and a security expert with 20 years of industry experience. In today’s episode of The Pragmatic Engineer, he joins me to talk about what security teams actually do, what developers should own, and where real-world risk enters modern codebases. We cover dependency risk, software composition analysis, CVEs, dynamic testing, and how everyday development practices affect security outcomes. Johannes also explains where AI meaningfully helps, where it introduces new failure modes, and why understanding the code you write and ship remains the most reliable defense. If you build and ship software, this episode is a practical guide to thinking about code security under real-world engineering constraints. — Timestamps (00:00) Intro (02:31) What is penetration testing?

LaTeX has been the preferred system for writing scientific and mathematical documents for many years, and today it is a key part of a data scientist's tools. This talk provides a brief history of LaTeX, an overview of the concepts, and live demos of some modern tools which have LaTeX integrated - from full document preparation systems, embedding in Python notebooks, to JavaScript libraries for use on the web. The aim of the talk - which requires no expertise - is to give you enough understanding of LaTex concepts that you can more easily use it in future projects if the need arises.

Deux royaumes s’opposent depuis des âges immémoriaux, séparés par une rivalité sans fin. D’un côté, le puissant royaume du Frontend, avec son JavaScript omnipotent, façonnant des interfaces dignes des plus grandes cités elfiques. De l’autre, le robuste empire du Backend, maître incontesté des données, envoyant ses légions de JSON dans une bataille sans merci. Une prophétie murmure le nom d’un artefact légendaire, forgé pour unir ces royaumes ennemis : Inertia js. Découvrirons son véritable pouvoir à travers du code concret et, peut-être, ramènerons enfin la paix dans le royaume du développement web.

NiceGUI is a Python-based web UI framework that enables developers to build interactive web applications without using JavaScript. In this talk, I’ll share how my team used NiceGUI to create an internal A/B testing platform entirely in Python. I’ll discuss the key requirements for the platform, why we chose NiceGUI, and how it helped us design the UI, display results, and integrate with the backend. This session will demonstrate how NiceGUI simplifies development, reduces frontend complexity, and speeds up internal tool creation for Python developers.
