Een beetje hackersconferentie heeft een hippe badge die meer computer dan identificatiemiddel is. Cybersecuritybijeenkomst OrangeCon wil ook een mini-pc als badge aan bezoekers geven, maar dan wel eentje waarmee je ook na afloop iets kunt. Daarom krijgen bezoekers van de con een ESP32-module die ze later als smarthomecontroller kunnen gebruiken.

Look people, no matter how much we destroy the Earth by polluting it with CO₂, microplastics, PFAS, etc. everywhere, and even if AMOC shuts down and both the Greenland and Antarctic ice sheets melt, the Earth will still be infinitely more habitable than Mars. Mars is a shithole and we're not going.

Always good to talk to Mikko, he's always interesting but this career change was a surprise. That said, with Russia on the border it's a perfectly understandable move. "I do believe anti-drone technology maybe has more importance, and more meaning to it, right now with the war raging on."
