I’m really happy to share that I'll be traveling to Paris to speak at @KernelRecipes in the week after the Open Source Summit Europe. ✈️🇨🇵🗣️🎙️ I’m really excited about this edition, and as always, feel free to say hi if you see me around. 🙂👋🏽🐧 #Linux embeddedor.com/blog/2024/06/2…

That was #kr2024. Another great edition. Feel like it lasts a couple of hours only ( but the fatigue tells me it's not). I'll all miss you till next year. The positive energy received there is a great self-booster. Thanks all for making Kernel Recipes such an amazing event 🙏

This morning I'll lead the largest charity auctions ever made at @KernelRecipes in favor of @larsaodomingos. Thanks @Dell France for the support.
