Right, but you don't want to live with the fear of a random bit flip when working with compilers 😭

Better to keep cheating...

@lkundrak compilers are also confusing, but at least (we assume) their behaviors are deterministic, unlike electrons and holes :D

There are a few remaining things I want to learn while I'm still an undergraduate:
Compilers, Electronic Circuit and VLSI

The latter two are tough and confusing...

OK, here's a take for you:

PDFs are not a document format. Instead, as they encapsulate an executable (postscript) and a set of resources that are accessed in a sandboxed environment, they constitute a container.

This is what I've been developing at Purdue: detecting where the last reference to a memory was lost, aiming to help fix memory leaks. It's written on top of the LLVM compiler infrastructure.

It's still in development as an out-of-tree project and needs some more work :)
However, I believe this could help in resolving memory leaks.

Good bye Purdue University!

It has been so intense, now suffering from jet lag and getting back to real life.
