Subsurface
Its dive planning and dive logging software. It’s also the only software I’m aware of that can actually pull the data from my dive computer, which uses some crappy proprietary cable and software. The fact that subsurface exists and is automatically in Linux repositories is what finally allowed me wipe out my aging and barely functioning computer, and revive it with Linux.
Even if you convinced me that PFAS are 100% safe and benign and absolutely never make it from the pan into our food…I’d still support banning them because of how nuclear they are to everybody involved with or living near, wherever they’re manufactured. Seems like a lot of unnecessary risk just for a slightly more convenient non-stick layer.
