When you have surplus photovoltaic capacity — an increasingly common situation — you could turn it to electrolysis. You still have to pay for the equipment, but it sounds like it could be pretty cheap. It would cut out the cost of mining, a

This is so true, and so wrong. We will look back and see it as outright barbarism. I think we're headed towards a major Constitution revision (or a sequel to the Declaration of Independence) within a couple of generations, and the &quo

Some big auth providers throw in a few extra signals too. Your IP address changes? That might hurry up expiration a little. Your user agent changes? Big red flag. Etc.

And using biometrics is itself a hack to circumvent the vagaries of government ID systems. So you'd be hacking around a hack. It makes me think at some point we'll be back to inventing government-issued IDs. Or um using the ones w
