DRM is orthagonal to ownership

I never used npp as my code editor but as a secondary program that i kept notes in and would paste text in to manipulate then move back into code editor. It had a rich plugin ecosystem way before that was common. I use Kate for those purposes instead now

I like kate in general but I can’t seem to get it to use semantic highlighting with gopls

The way that rust attempts to prevent this class of error is not by making an implementation of free that is safe to call twice, but by making the compiler refuse to compile programs where free could be called twice on a pointer.

Anyway, use after free doesn’t depend on a double free. It just means that the program frees memory but keeps the pointer (which now points at memory that could contain unrelated data at some future point in time) and if someone trying to exploit the program finds a way to induce the program to read or write to that memory they may be able to access data they are not expected to, or write data to be used by a different part of the program that they shouldn’t be able to

Tampermonkey is one of the few that have already been available
