Turns out it's possible to violate safety in Rust with Rc and integer overflow:
Rc is unsafe [mostly on 32-bit targets] due to overflow
Rc is unsafe [mostly on 32-bit targets] due to overflow
The reference counts in RcBox are of type usize, and creating a new Rc increments it with regular addition. In optimized code, where overflow checks are removed, it is possible to overflow this count, allowing a use-after-free. In the old world where values supposedly could not be forgotten (without running the destructor) without actually leaking memory, it would be impossible for this to wrap around: doing so requires 2^X Rcs where X is the pointer width, ergo sizeof(Rc) * 2^X bytes, which o...

I've put on my retrocomputing hat today and emailed Symbolics regarding purchasing a license for Genera. I'm hoping it's cheap.

Today's hidden Emacs gem: pressing C-c C-b in an ielm buffer lets you associate it with a buffer, so you can inspect buffer-local variables.

If I want to link to a specific heading on a webpage, I have to open a DOM inspector to find out if there is an ID. Is there no better way?
