Supreme leader mad
  • Torvalds just really dislikes C++. He's gone on the record saying that he thinks it's just not a good language. In his own words "C++ is just a waste, there is no design at all, just adding some scum on top of C."

  • Hooooooooooooooooooot
  • Some types of fusion can bypass steam generation and use what's creatively called Direct Energy Conversion. If the fusion products are charged particles they can be passed through a magnetic field to separate them based on charge and collected onto plates. When you look at the electric potential between the plates you've effectively created a voltage, no steam necessary. It's also theoretically possible to do the same with some types of fission products too.

  • Why build megastructures? Just move planets around to make habitable worlds
  • Because planets are terribly inefficient? Their livable area per mass is very low. You could deconstruct a planet and use the materials to make O'Neill cylinders (or similar) that can comfortably hold many orders of magnitude more people. It's also very energy expensive to go up and down the gravity well of a planet, increasing the cost of all space-related industry, shipping and transport. For a interplanetary civilisation that's a huge cost. Artificial habitats have no such problem.

    It's interesting the article focuses so much on Dyson spheres considering they're probably the least practical megastructure. Dyson swarms are a much more practical and accepted concept, hell it's one of the things that astrophysicists are actually looking for out there.

  • What happened?
  • As other people have said, oozing. In addition to their fixes I would suggest looking into sequential printing as a print method to be aware of. Rather than printing two objects layer-by-layer, sequential printing will complete all the layers of one object before starting on the next. This has the major benefit that you get zero oozing or stringing between parts. This can be a lifesaver on materials like PETG that will always string to some extent. The only gotcha is that you have to place the parts further apart on the print bed, as the extruder will collide with any nearby completed parts (Prusa slicer has all of this built in, including alerting you if any collisions would occur). I don't recommend it for every print, but it's a useful tool to have in your toolbox.
