John Perry Barlow’s ‘Principles of Adult Behavior’

  1. Be patient. No matter what.
  2. Don’t badmouth: Assign responsibility, never blame. Say nothing behind another’s back you’d be unwilling to say, in exactly the same tone and language, to his face.
  3. Never assume the motives of others are, to them, less noble than yours are to you.
  4. Expand your sense of the possible.
  5. Don’t trouble yourself with matters you truly cannot change.
  6. Expect no more of anyone than you yourself can deliver.
  7. Tolerate ambiguity.
  8. Laugh at yourself frequently.
  9. Concern yourself with what is right rather than whom is right.
  10. Never forget that, no matter how certain, you might be wrong.
  11. Give up blood sports.
  12. Remember that your life belongs to others as well. Do not endanger it frivolously. And never endanger the life of another.
  13. Never lie to anyone for any reason.
  14. Learn the needs of those around you and respect them.
  15. Avoid the pursuit of happiness. Seek to define your mission and pursue that.
  16. Reduce your use of the first personal pronoun.
  17. Praise at least as often as you disparage.
  18. Never let your errors pass without admission.
  19. Become less suspicious of joy.
  20. Understand humility.
  21. Forgive.
  22. Foster dignity.
  23. Live memorably.
  24. Love yourself.
  25. Endure.

I don’t expect the perfect attainment of these principles. However, I post them as a standard for my conduct as an adult. Should any of my friends or colleagues catch me violating any one of them, bust me.

9 Tools for Detecting B**lsh*t

found at [the marginalian]

  1. Wherever possible there must be independent confirmation of the “facts.”
  2. Encourage substantive debate on the evidence by knowledgeable proponents of all points of view.
  3. Arguments from authority carry little weight — “authorities” have made mistakes in the past. They will do so again in the future. Perhaps a better way to say it is that in science there are no authorities; at most, there are experts.
  4. Spin more than one hypothesis. If there’s something to be explained, think of all the different ways in which it could be explained. Then think of tests by which you might systematically disprove each of the alternatives. What survives, the hypothesis that resists disproof in this Darwinian selection among “multiple working hypotheses,” has a much better chance of being the right answer than if you had simply run with the first idea that caught your fancy.
  5. Try not to get overly attached to a hypothesis just because it’s yours. It’s only a way station in the pursuit of knowledge. Ask yourself why you like the idea. Compare it fairly with the alternatives. See if you can find reasons for rejecting it. If you don’t, others will.
  6. Quantify. If whatever it is you’re explaining has some measure, some numerical quantity attached to it, you’ll be much better able to discriminate among competing hypotheses. What is vague and qualitative is open to many explanations. Of course there are truths to be sought in the many qualitative issues we are obliged to confront, but finding them is more challenging.
  7. If there’s a chain of argument, every link in the chain must work (including the premise) — not just most of them.
  8. Occam’s Razor. This convenient rule-of-thumb urges us when faced with two hypotheses that explain the data equally well to choose the simpler.
  9. Always ask whether the hypothesis can be, at least in principle, falsified. Propositions that are untestable, unfalsifiable are not worth much. Consider the grand idea that our Universe and everything in it is just an elementary particle — an electron, say — in a much bigger Cosmos. But if we can never acquire information from outside our Universe, is not the idea incapable of disproof? You must be able to check assertions out. Inveterate skeptics must be given the chance to follow your reasoning, to duplicate your experiments and see if they get the same result.

SuperSlicer

https://github.com/supermerill/SuperSlicer/releases/tag/2.4.58.3

SuperSlicer takes 3D models (STL, OBJ, AMF) and converts them into G-code instructions for FFF printers or PNG layers for mSLA 3D printers. It’s compatible with any modern printer based on the RepRap toolchain which is running a firmware based on Marlin, Prusa, Klipper, etc.

SuperSlicer is based on PrusaSlicer by Prusa Research. PrusaSlicer is based on Slic3r by Alessandro Ranellucci and the RepRap community.
