Will Tesla's camera-only autonomy prove its mettle?

» I'm still not convinced that Tesla's camera-only approach will work well in all situations. According to a quick AI search, Elon doesn't like Lidar based on "cost, complexity, and philosophical disagreement with its necessity". Other manufacturers seem to have no problem with the first two of these and I challenge his last reason. I would have thought that a combination of available technologies would give you the safest options for all circumstances.
True cost of mining Bitcoin

» Should you Bitcoin? Short answer in the past yes, now not so much. I've mentioned Bitcoins in previous articles and modern mining, which is how you get them, has driven up the price of graphics processors in recent times. Can you make any money using your spare GPU cycles on your PC? Answering that question is not as simple you might think, despite what a mining application may tell you. It depends on how powerful your GPU is, what the price of Bitcoin is that week and things like how much you pay for your power because you will be using more. The process works by maximising the power of your GPU, using more electricity than for regular use and keeping your PC hotter than usual 24/7. Mining works by solving complex maths equations for the blockchain which over time takes longer and longer and more processing power.
