L'IA ne touche que 21 % des tâches, Google l'a mesuré

Google a passé au crible 15 millions d'interactions avec ses outils d'IA pour savoir ce que l'intelligence artificielle fait réellement de nos journées. Sa première étude AI & Economy ATLAS en tire deux mesures qui ne racontent pas la même histoire : Gemini est utilisé dans 68 % des métiers, mais n'intervient que sur 21 % des tâches à l'intérieur de chacun d'eux. Entre les deux, il y a la dist...

I Built a Zero-Knowledge Protocol to Prove a Human Typed This (Not a Bot) — Help Me Try to Break It

AI-generated text is no longer distinguishable from human text. That's not a hot take, it's a measurable fact at this point, and it quietly breaks a lot of the trust assumptions the internet runs on — messaging, marketplaces, escrow, forums. If you can no longer tell what was written by a bot, the obvious next question is: can you tell how it was written? That's the premise behind PoHI (Proof of ...

Important Design Patterns in a Nutshell

When building complex software systems, writing code that simply "works" is not enough. As systems scale and requirements evolve, poorly structured object creation, tight coupling, hardcoded control flows, and static inheritance hierarchies lead to fragile architectures. This comprehensive guide breaks down five essential design patterns—Abstract Factory, Strategy, Adapter, Observer, and Decorat...

AI Governance for Enterprise AI: Why Governance Comes Before the Gateway

Governance decides what AI is allowed to do. The gateway only enforces it. Every technology shift follows the same pattern. A new platform emerges, early adopters rush to experiment, vendors race to ship features, and before long every conference talk is a benchmark chart. Enterprise AI is no different, and one of the fastest growing categories in enterprise infrastructure right now is the AI ga...

I gave the same fabricated answer to RAGAS and DeepEval. One scored it 0.0. The other scored it 1.0

Here's an output from a RAG system asserting a pricing claim it was never given, for a question its context couldn't answer. I ran it past the two most popular LLM-as-judge faithfulness metrics, five times each, judges on gpt-4o at temperature 0 — the setting most favourable to judge stability. RAGAS scored it 0.000. DeepEval scored it 1.000 — in all five repeats — and explained itself: "The sco...

Enterprise State Management: React & Zustand 🐻

The Collapse of React Context State management is the most heavily debated topic in the React ecosystem. For years, Redux was the undisputed king, but its massive boilerplate and steep learning curve led many teams to seek alternatives. When React introduced the Context API, many developers assumed it was the ultimate state management replacement. Unfortunately, in enterprise applications, using ...

Anonymous survey design starts with a data inventory, not a checkbox

“Anonymous” is often implemented as a missing name field. That is a start, but it is not a design method. A survey can omit a name and still connect an answer to an account, invitation token, IP address, cookie, device identifier, tiny team, or revealing free-text detail. The useful engineering question is: Which identity paths does this task actually need, and what happens if we remove each o...

Testing Non-Deterministic LLM Pipelines in CI: A Contract-Based Approach

Most CI pipelines assume a function called with the same input twice returns the same output. That assumption breaks the moment an LLM call enters your test suite. Ask GPT-4 or Claude the same question twice and you can get two different (both correct) answers. Teams shipping LLM-backed features often respond to this by writing almost no tests for the LLM-touching code paths, or by asserting on ex...

I built a small open-source scanner for API-key mistakes in vibe-coded projects

I started this project because vibe coding makes it possible to get an app working before a beginner has learned how secrets, frontend bundles, or Git history behave. A value being in .env does not always mean it stays private. Variables such as VITE_*, NEXT_PUBLIC_*, and REACT_APP_* can reach browser code. And if an API key was committed, deleting it from the current file does not remove it from...
