RéseauxSecurité In recent years, the ways that we can deliver HTTP has improved in occasional leaps, from 1.0, 1.1, a big step to 2.0, and now 3.0. One of the biggest obstacles has been TCP, which isn't a great fit for HTTP, but we are stuck with it – or are we? QUIC is a reimagining of TCP that runs over "the other protocol", UDP, giving us yet another step up in performance and security. Discover how it works, and how you can deploy it today.

Attend this session for insights on crafting a domain model tailored to web needs within a hexagonal architecture framework.
Intelligence Artificielle The ascent of machine learning, especially large language models (LLMs), comes with exorbitant infrastructure costs, making it almost unfeasible for individuals to run such programs independently. Amazon, Azure, and Google Cloud dominate with over 60% market share. This concentration challenges the decentralized essence of the internet, potentially impacting innovation, quality, and freedom.
JavaScriptIntelligence Artificielle Prompts are like magic spells, using words to achieve impossible effects but requiring complex rules. AI agents are like a wizard who consults spell book to cast a series of spells.
