  • I think time wasn’t super kind to it. And I don’t remember how clear it was in the movie that Scott’s just not a good dude. My memory of the story is that the core is: Scott is bad. Scott accepts that. Scott starts doing better. But maybe that’s just my headcannon.

    It’s a good lesson though! Just because you were bad doesn’t mean you are bad. You can change. Life isn’t a simplistic video game. It’s a lesson I’ve needed from time to time.






  • I’ve always wondered about Unicode normalization and passwords. I don’t know a ton about it, but I think it’s that things like ö and be represented as one character for the whole thing or two, one for the umlaut and another for o. That means that there are at least two sequences of code points that make the same… Glyph? I forget the word. The thing you see on the screen.

    Anyway, what if you have that ö in your password and one browser/keyboard/os/lovecraftian nightmare makes the mark one way and the other does it the other way? They aren’t the same bytes. So they won’t hash the same and you just can’t tell why. Without digging super deep.

    There are standard ways to normalize the Unicode but I don’t imagine most password systems use them. Maybe it’s some intermediate layer. But I kind of doubt it. Those are complex, evolving standards.

    Oh. And that “evolving” thing might make trouble for password systems. Are these standards backwards compatible in the way they’d need to be for a normalization upgrade not to break any passwords?

    Oh God, what nightmare have I found?
