First speaker of the day is @wbauweraerts on moving from fragile to fearless tests. Perfect breakdown on how testing should be used to be able to test and deploy with confidence 💪🏼

Found the only sporty challenge at @Devoxx : “How fast can you throw a baseball ? ⚾️” And I smashed the record with a 113 km/h… and now my arm is all pins and needles, worth it though 🤣

I’ve been saying this for over three years now: Soon we’ll have Netflix-with-Prompts, where you describe what you want to see, and you and your friends and family can even star in it.

the feature i have worked the hardest and most recently on is Cameos, which lets you make videos starring you or your friends i have met multiple people internally at openai after seeing videos of them show up in the app, and it has felt like we already have something in common

Unitree G1 has mastered more quirky skills 🤩 Unitree G1 has learned the "Anti-Gravity" mode: stability is greatly improved under any action sequence, and even if it falls, it can quickly get back up.

The more I read about Posit/Unum number format (as an alternative to IEEE 754 floating point) the more I like it/want it. Deep learning could benefit greatly from its tapered precision around 1.0. And its quire accumulator could reduce a lot of computational error.
