So who is going to start the FOSS smart TV firmware alternative that I can use as a replacement for Samsung firmware? Or do DRM requirements for apps like Netflix make that impossible?
Main complaint with Facebook is how rigid the friendships are. There are people I'm friends with on Facebook that I haven't spoken to in ten years. But it feels weird to delete them. For some reason it feels natural to add everyone you know, even if you've only ever spoken to them for a single evening. To put it another way the edges of the Facebook friend graph don't have weights where the IRL graph does.
Ohm's law is an empirical law that only holds in certain circumstances. A classic exercise is measuring the current and voltage across a lightbulb, plotting it, and measuring the slope of the line. The slope is the impedance. Then you turn up the voltage and watch the line turn into a curve, which is where the law breaks down and doesn't apply anymore. The engineers treat it like a definition and assume linearity over all voltage.
