I created a company called "Invisible Computers GmbH" to make and sell an e-paper smart display:

You can email the company (aka me) at info@invisible-computers.com

  1. I’m building a better charging optimisation for electric cars.

    It plans multiple days ahead to make the best use of low prices and surplus solar.

    It can use the vehicle api or the charger api to control charging.

  2. This is not a philosophical discussion
  3. It’s scary, but I think most people react rather positively once they understand that you aren’t trying to force them into something, but rather are trying to see if it’s possible to create a positive - sum result for both parties.
  4. I have a backend that connects to the calendar providers and then renders the content for the display.
  5. Talking to local salons is a great next step, i hope you will get some good feedback!
  6. Hey,what do you do sounds interesting. Do you have clients already?
  7. I am still working in my epaper calendars, now making a 10 inch display: https://shop.invisible-computers.com/products/invisible-cale...

    More broadly, I’m working on replacing my day job with something more exciting and impactful.

    I think the most excitement and impact can be found in a startup, so that’s what im trying to get into now!

  8. After an oligarchy, looks like the us is also getting a planned economy now.
  9. I like HN because you can have interesting discussions, and because people usually argue their points.

    I think this is the first time that someone has responded to me in such a mean-spirited way, while providing no substantive response.

    I would prefer if you left this forum.

  10. > say, a 1 to 20 bet that German democracy will itself self-immolate in, say, 15 years.

    I don’t see why it matters where I am located, but if we must talk about Germany then yes, I would say the odds are higher than that actually.

  11. To your last point: I think that the current threat to American democracy is partially caused by a lack of education.

    There is no reason that anti-wokeism had to come with totalitarian tendencies.

  12. I would prefer books to make correct points, such as “education is really important, but some education is not really useful except for signalling”
  13. The thing is that education is important. Some of it is signalling, but not all of it is useless.

    There was a time when most people couldn’t read or do basic algebra and you don’t want to go back to this.

    Even a dumb kid can understand compound interest and absolutely has to in order to thrive in our society.

  14. Children’s intelligence is strongly correlated with parental intelligence, probably due to both nature and nurture.
  15. Btw, I used “you” as a reference to the sovereign democracy society, not the government.
  16. That’s how all dictatorships work.

    Everything is illegal.

    You live by the KING.

  17. Everyone lives and dies by the KING now.
  18. I think we as Europeans would do better if we actually defended against Russia's hybrid warfare.

    I understand all these principled stances and I do support them ethically, but sometimes you have no choice but to choose the lesser evil.

  19. And if you have free speech without exceptions, foreign actors will see it as a weakness and use it to brain rot your society.
  20. Print debugging gives you more of a Birds Eye view on the bug search.

    Stepping through code is more like having your nose on the ground.

    Both have their merits.

  21. The first step for allowing local reasoning is to break your product into independent subdomains that are as independent as possible.

    For a software company, this means crafting the product ownership of your team such that the teams can act as independently as possible.

    This is where most companies already fail.

    Once this has been achieved, you can follow this pattern on smaller and smaller scales down to individual functions in your code.

  22. That’s basically why I called my company “Invisible Computers”.

    And it’s no coincidence that the first product is an epaper calendar :D

  23. Shouldn’t that be clear from considering angle properties?

    EDIT: Yes, I think it’s clear considering that the sum of the non-rectangular angles in a triangle is 90 degrees.

  24. I guess my intuition for vector algebra is much weaker...
  25. The expression immediately follows from

    a ( b+c) = ab + ac.

    I agree it's important that students intuitively feel that

    a ( b+c) = ab + ac

    is true.

    But once we are at that, why would we even bother to teach or "proof" all variations of that expression?

  26. Here is a visual proof for the Pythagorean theorem:

    https://www.dbai.tuwien.ac.at/proj/pf2html/proofs/pythagoras...

    I find this much more "useful" since the Pythagorean theorem isn't immediately intuitive to me.

    As for the proof in the original post, it seems really redundant to me. it follows from a (b+c) = ab + ac.

    And while building intuition for this distributive property of multiplication is extremely essential when teaching maths, I feel that the intuition for why this is true is better built without leaning on geometry.

  27. Millions of people are hooked up to a terminal as well.
