"Yes, it is. It's amazing how quickly it has destroyed dev, sec, ops, management, company missions and priorities, regulations, information literacy, and civil society, making everyone more vulnerable."

bert hubert 🇺🇦🇪🇺🇺🇦

Only answer if you have direct and personal experience please. Is there ANY way on IOS (NOT ON ANDROID) to get Signal to help you clean its massive storage? I've manually tried to delete some large things but it is not helping. It is using 11GB and I can't do a thing anymore. Help?

Hello Mastodon!

Since this is my first post, I thought I'd share some incredibly niche C++ trivia / pedantry:

For an enum whose enumerators all have the value 0, C++ asks us to imagine a hypothetical integer type with minimal width that can represent 0 (https://eel.is/c++draft/dcl.enum#8.sentence-2). This means we must consider the case where the width is 0. For an unsigned integer type, this gives a range of representable values of [0, 0], and that's the type we pick. But before we can determine that that's minimal, we must also consider a signed integer type with a width of 0, for which we get a range of representable values of [-½, -½]! (https://eel.is/c++draft/basic.fundamental#1.sentence-5) Conveniently that range does not include 0, so we discover that we must use an unsigned integer type to determine the range of values of the enumeration. (We also rule out an unsigned integer type of negative width as that would have a range of values 0 to -½ (inclusive) or smaller, which I think we can reasonably conclude is an empty range despite the parenthetical.)

In any case: if you ever wondered whether a zero-bit signed integer type in C++ can represent only the value 0 or only the value -1, now you know: no, it can represent only the value -½. Truly a marvelous compromise.

Follow me for more brilliant insights like this one :)
