In this episode of Destination Linux, we explore a Bluetooth mesh chat app for doomsday scenarios, discussing its decentralized communication. We address community feedback on Wayland and X11 compatibility issues for NVIDIA users and introduce an open-source gaming project enhancing Linux performance with lossless scaling. We also highlight Ploopy’s customizable dial for creative workflows and talk about SpeechNote, a privacy-focused offline speech-to-text application. All of this and more on this episode of Destination Linux.
