What Hacker News says
3 sourcesFrap: Formal Reasoning About Programs
2 points · Open discussionMy current reading list:
- Fundamental Proof Methods in Computer Science
- Handbook of Practical Logic and Automated Reasoning
- Software Abstractions
- The Little Prover
Yes, currently I have Athena, OCaml, Alloy, ACL2 (via Dr Racket/Dracula) all up and running to work through the exercises in these books. I'm very skeptical anything will come of this, but it interests me and I can see the value.
Hopefully the speaker's next book Formal Reasoning About Programs (https://github.com/achlipala/frap) will be a nice next step, I have Certified Programming with Dependent Types but have not cracked it yet. Also keeping an eye on Verified Functional Algorithms (https://softwarefoundations.cis.upenn.edu/vfa-current/index....).
