Current UI text looks blurry in Chrome and Firefox, probably because it's using a font that's optimized for 11px but font-size is scaled to 13.75px.

The first example should have changed the heading to "C++ code" as opposed to "C code" due to the use of `std::unreachable()`. This matches the godbolt link.

Another alternative is to use `__builtin_unreachable()` (not standard, but available in GCC and Clang).

Lesson here is that the subdomain names can be queried due to passive DNS records, and putting stuff that is not supposed to be guessable in subdomain names is a bad idea.

Maybe the pull from a string/leash would affect how the thing flies, kind of like kites.

I like how he built a test stand near 7:22, which solves the motor flying off problem and is probably easier to iterate on. It reminds me of how rockets are tested.

Going for paid membership is a bold move. It's also not obvious who is handling payment information, the terms of service only says payment will be processed by a third party.

GCC still not implementing the standard pragmas reminds me of the old GCC pragma easter egg. This is in cccp.c from gcc 0.9:

    /*
     * the behavior of the #pragma directive is implementation defined.
     * this implementation defines it as follows.
     */
    do_pragma ()
    {
      close (0);
      if (open ("/dev/tty", O_RDONLY) != 0)
        goto nope;
      close (1);
      if (open ("/dev/tty", O_WRONLY) != 1)
        goto nope;
      execl ("/usr/games/hack", "#pragma", 0);
      execl ("/usr/games/rogue", "#pragma", 0);
      execl ("/usr/new/emacs", "-f", "hanoi", "9", "-kill", 0);
      execl ("/usr/local/emacs", "-f", "hanoi", "9", "-kill", 0);
    nope:
      fatal ("You are in a maze of twisty compiler features, all different");
    }

It's gone by gcc 1.21:

    #if 0
    /* This was a fun hack, but #pragma seems to start to be useful.
       By failing to recognize it, we pass it through unchanged to cc1.  */
    ...
    #endif
