What are some good resources to learn to write very reliable/formally verifiable software? (lemmy.world)

The University of Pennsylvania offers a free series of books called Software Foundations with the following description:

The Software Foundations series is a broad introduction to the mathematical underpinnings of reliable software.

The principal novelty of the series is that every detail is one hundred percent formalized and machine-checked: the entire text of each volume, including the exercises, is literally a "proof script" for the Coq proof assistant.

The series includes Verifiable C, which seems very appealing as a way to avoid some of C's infamous "footguns." I haven't read the series myself, but I might in the future because I like math, logic & programs that do what they're supposed to do.

Are there any materials that would be good as alternatives or complements to this series?

Right, in effect you break down the possible function states along with a more rigorous form of targeted unit testing.

I don’t believe they used coq, but the sel4 Linux kernel is one of the most famous formally verified applications/systems.

The way to beat vulnerabilities is to use formally verified building blocks in my opinion.
