​Building and deploying a model in the browser to do gesture recognition

​This talk demonstrates how to implement live gesture recognition in browsers using machine learning and React, with MediaPipe for hand detection and TensorFlow for classification. We will covers the pipeline from model training to deployment in a browser.

​About Gabriel

​Local-first Has a Branding Problem

​Is "React on the Server, Postgres on the Client" the new normal? Well, probably not for 99% of you. The truth is that local-first software development hasn't really caught on yet. And hearing about Linear and Figma as the de facto references is getting kind of old. Why haven't local-first architectures become more popular? I fundamentally believe that local-first has a branding problem. The term "local-first" itself drives many of us towards an instinctive repulse — "Oh no, not that fad again", or "Why would I even need local-first?".

​In this talk, I'll make my case for why local-first has a branding problem, and how we should be thinking about it (hint: local-first is about much more than local first). I'll walk through some examples with both Zero and ElectricSQL, so we won't end up in a theoretical snoozefest.

​Subject 3 by Nicolas Dubien

​The Tests That Write Themselves (Almost)

​Imagine a world where writing tests doesn't demand years of experience, where considering every edge case is not a requirement, and where expressing your expectations is enough to validate your code. Let's add a glimpse of magic in our tests, let's discover the world of property-based testing!

​Inherited from the functional world, this technique offers a unique approach to validate your code. When applied in conjunction with traditional testing techniques, it becomes a powerful ally in detecting hidden bugs before your users even notice them. Unlike conventional tests, the key isn't to hardcode inputs but to let the framework build them and think about the edge cases for you.

​Let's discover this unique technique together!
