    I bet a lot more people know what 0°C feels like than 0°F. One is freezing point, one is a completely arbitrary temperature which only gets called “the lowest you’ll experience” as a post hoc rationalisation of Fahrenheit. Most people will never experience anything that cold, some people experience colder.

    I even bet more people know what 100°C feels like than 100°F. One is accidentally getting scalded by boiling water, the other is a completely arbitrary temperature which is quite hot but not even the hottest you’ll experience in America.







  • To be clear, absolutely no one has replicated zero resistance, which is the only thing that matters for a superconductor.

    All of the “successful replications” so far have just been tiny flakes of material moving in a magnetic field. No one has even got it to fully levitate, they all stand on one end, which any ferromagnet would do. One video demonstrated that a flake was not attracted to the magnet, which could rule out ferromagnetism. Even assuming that’s true it could still just be diamagnetic - pyrolytic carbon behaves exactly the same way and it’s not a superconductor.





  • What happened was, up until the early 2010s a lot of frontend developers were essentially designers who could write HTML/CSS templates, but not programs. When the industry shifted to client side SPAs they couldn’t follow, so there was a big backlash against the new “complicated” tooling, even though it’s no more complicated than any other domain.

    I always wanted to write a response post, “How it feels to learn JavaScript in 1996”. Because yes, webpack is harder than flat JS files. But you have 1 billion tutorial videos to help you do it, and open source project skeletons to start you off, and Q&A sites to fix your problems for you.

    Some of us learned JS before YouTube or StackOverflow or even W3Schools existed. When I got my first job browsers didn’t even have developer tools! If your code didn’t work you just had to guess why!
