   Exactly. CGI is just movie magic. And now some real world tech demos are sufficiently advanced to be indistinguishable from CGI/magic.

   The skepticism is warranted for any bleeding edge technology. I wonder if there's another version of a Turing test when a technology can be considered sufficiently advanced when it's indistinguishable from a fake version you'

   In Accelerando [1], humanity becomes a Type II civilization and builds a Matrioshka swarm. But it shines sunlight on Earth by opening up a hole in the swarm so that the sun is visible to Earth. That would allow harnessing almost all of the

   This seems very inefficient due to the high energy cost and the long timescales in the proposal. The long timescales means it would be hard to adapt this method to counteract rapid weather & climate fluctuations. A better option to cont

    I'm fuzzing the math a bit, but assume you have a Saturn V style rocket that can get 100 tons into orbit. And that consists of 50 tons of spaceship and 50 tons of fuel. Then you get something like V_e * ln((50+50)/50) = .69 * V_e

    Nice work. I'm always a fan of custom raytracers since I feel that they're projects that everyone in CS should do once. It's possible to get a raytracer built in a day [1][2], but you can also endlessly expand the project to

    For the HN crowd, it's probably worthwhile to split "STEM" into "high-end engineering" and "normal engineering". The former is suffering from a labor shortage which is why FAANGs and similar companies are
