anthropic.comLLMs are making formal software verification feasible at a much larger scaleClaude formally proved security properties in the compiled code of 123 open-source libraries. Along the way, it found bugs that had eluded detection for years.

Formal verification is the new Borgian map, only instead of being 1:1, “Proofs can be many times larger than the original code … it took two person-years to implement the seL4 operating system kernel, but 20 person-years to formally verify it.” www.anthropic.com/research/for...

I have begun a new creative project & have been reading lots of academic articles to educate myself on the subject, which has had the unintended consequence of reminding me how much I enjoy the deep expertise of peer reviewed writing. People mock the limited audience, but there's real beauty in it.

Historically, registries answered a simple question: “Can I download this package?” Today’s tooling increasingly asks a different question: “Should I and how?” 1/3 redmonk.com/kholterhoff/...

For Part 2 of my @redmonk.com series on why modern software registries are a trust service, I look at hardened container images, where the trust-service model is furthest along. I then trace the same model in extension registries, where the Eclipse Foundation now sells an SLA on Open VSX. 2/3

And @microsoft.com's Visual Studio Marketplace restricts extension use to Microsoft products. I argue the pattern across these markets is the same: the artifact is free, assurance is the product. 3/3
