#kani — Public Fediverse posts

56 minutes pinned to a single Apple M1 core running CBMC with the brilliant #kani #rustlang verifier—all to formally prove the floating-point bounds of a one-pole DSP filter. I finally got my Q.E.D., and that feeling never gets old.

The best part? I'm not verifying this codebase to satisfy a tedious compliance checklist. This isn't software engineering; it's purely recreational artwork for the love of aesthetics.

Kivuttomalla on alkanut välipäiväale. Tilasin just Laikalle painepaidan ja viilennysliivin, hinta postituksineen 21 ja risat. Älyttömän halpaa.

Carolyn is also a maintainer of #Kani, the Rust model checker.
She has been so supportive and kind during my struggles with HashMaps and Kani 🥺

Totally agree! Unit tests and usage of #LLMs in that area are a bad combo (both for implementation and tests).

However, I'd like to give you some "food for thought":
What if the LLM was generating code against a (human written) #proof?

See this blog post, where they've written a proof with #Kani, a model checker in #Rust and let the #LLM generate the implementation until the proof passes:

I'm only like 10% into the tutorial, but this language is CRAZY (fun)! :awesome: 😄

I try to learn the fundamentals of it, so I can use the backend of it in #Aeneas... so I can ultimately formally verify my #Rust crate (former attempts with #Creusot and #Kani failed for me).

See part two of toot for a toy example of proving function equivalence

Kotia kävellessä syrämessä läikähti ja naamaan levisi leveä hymy, kun keski-ikäinen pariskunta ulkoillutti kahta kania Fredrika Runeberginpuistossa. Olivat aika isoja pupusia; toinen tummanharmaa, toinen valkea mustin merkein. Niin suloisia! (Mulla oli kaneja varhaisteinistä nuoreen aikuisuuteen).

Perään tuli helpotuksen huokaus - onneksi olin itekseni liikenteessä, #riistaviettinen #Laika olisi voinut tehdä tuosta kohtaamisesta kaikkea muuta kuin suloisan!

Next in our #EverythingOpen Speaker Spotlight we have Tobin Harding who will take us through advanced #testing in @rustlang using tools like #Mutagen and #Kani
