Why HN links it
HN readers link Galois's blog for formal methods and high-assurance software work, including verification walkthroughs and tool write-ups such as SAW, Copilot, Ivory and c2rust. Many comments cite it as a source.
Summarised by Claude from a sample of 40 HN comments that link here. Each comment is marked recommending, critical or neutral (citing without judging); how this works.
For more than 25 years, Galois has combined mathematical rigor with curious creativity to guarantee trustworthiness in the world’s most critical systems.

I would check out https://pedestrianobservations.com/ for information on other but analogous cost disease. Basically, no, it's not just a meme. American managerial culture (or even Anglosphere at large, as alleged there) really does suck. And no amount of crafty mechanism design gets around the fact that least exploitable system seems to be one where the civil service isn't maimed and the work is done in-house. Basi…

HN discussionGalois has a reputation for being one of the most visible and well-known shops associated with Haskell. I'm curious to see what they can accomplish. A little bit of poking showed this[0] coming up -- I definitely wonder if that's around the same direction they'll be taking. [0] https://galois.com/project/csfv-crowd-sourced-formal-verific...

HN discussionFrom an abstract PL theory POV, Haskell's key innovation over ML was HKTs. It was an experiment at the time, but one that was successful beyond all expectation: I cannot imagine designing a new PL without HKTs. (Note that Rust is also trying to add HKTs, but has been running into difficulties with type-based lifetime tracking IIRC.) Implicits are a generalisation of default arguments (I don't know where they were pi…

HN discussionIf you look around, the problem touted here was that formal verification was done, but independently for two different parts of the standard, in isolation. The layman answer that is formal verification should've been done on those systems after integration. I'm not sure how much that would've helped though, since the proofs for each of those was complex enough. And then actual code written tends to sway far away fro…

HN discussionIt's interesting to compare what Facebook does with how Galois organizes itself. They just published a blog post about how many traditional management functions are handled on a rotating basis—instead of having people who always manage, they have individual researchers and engineers step up to lead efforts on specific projects. This general approach even extends to firm-wide management (via a "Jedi council") and fin…
