@labarba it has also sparked an interesting discussion among proponents of the language: https://fortran-lang.discourse.group/t/an-evaluation-of-risks-associated-with-relying-on-fortran-for-mission-critical-codes-for-the-next-15-years/5644
Janet VertesiWell, if today is any indication there’s one thing SpaceX can do that NASA definitely can’t: Have a massive and much-hyped spacecraft blow up spectacularly after launch and then the camera pans to everyone applauding wildly and saying, “Wow, what a great test, we learned so much!” instead of “Wow, how dangerous and irresponsible, NASA has lost its touch, we can’t trust them, maybe should give all its money to some upstart company.”

I think it's interesting to talk about floating point's "safe zone" (things you can do with floating point that are Completely 100% Fine Actually) because I think sometimes folks see that floating point is weird and kind of... overreact and treat it as a Magical Thing that could unexpectedly break at any time.
“there are only 2^64 floating point numbers, of course they’re weird, it’s a miracle that it even works at all” was such a big a-ha moment for me the first time someone pointed this out to me

@b0rk how computers see numbers?
trying to figure out a title for this "how your CPU represents integers and floating point numbers" zine
so far the best idea is "inside the machine: integers and floating point" but that's not great
is there a site like https://float.exposed for utf-8? Like where you paste in a UTF-8 string and see how it's broken up into Unicode code points?
