| 2025-10-14 07:50:13 +0200 | <dminuoso> | jackdk: Regarding botan bindings, I think any approach focusing on native bindings to a cryptographic library is more healthy both on on a security perspective as well as future proofing. |

| 2025-10-14 07:51:02 +0200 | <dminuoso> | Especially since the crypton(ite) situation demonstrates, that even *if* we have some reliable cryptographic implementation it is dependent on probably just a single person. Having an ecosystem dependent on a bus-factor of 1 is just not healthy for the rest of hackage. |
| 2025-10-14 07:52:05 +0200 | <dminuoso> | Not entirely sure if your comment was hinting at paying the botan person to work on crypton instead for a while. |
| 2025-10-14 07:54:24 +0200 | <jackdk> | dminuoso: I agree with what you have written. I think binding a trusted native implementation is safer in the long run, and I am hopeful we can move the ecosystem onto something like botan one day |
| 2025-10-14 07:55:12 +0200 | <jackdk> | And to be clear, I do not think paying the botan person to shift to crypton would be a good idea |

| 2025-10-14 12:20:08 +0200 | <merijn> | You're relying on the order of type variables as part of the public interface of a library (which basically no library author considers for PVP decisions) and unless the library author explicitly `forall`'s the type variables on every function that's dependent on the whims of GHC |
| 2025-10-14 12:20:20 +0200 | <tomsmeding> | type applications would be more robust if they're allowed only on functions with an explicit type variable ordering |
| 2025-10-14 12:20:29 +0200 | <tomsmeding> | but then nobody would have used it because of the chicken-egg problem |
| 2025-10-14 12:20:44 +0200 | <merijn> | Which is far from hypothetical, since we've already had at least one GHC release where a type system rejiggle changed the order of inferred variables, leading to breakage |

| 2025-10-14 15:56:59 +0200 | <ski> | (and yea, i was reminded of this, by the talk about `Monoid (Map k v)'. if we ignore the multiplication (and subtraction/negation) in the monoid ring, then `k' corresponds to the set of indeterminates (generators) in the "polynomials", and `v' corresponds to the monoid of coefficients) |
| 2025-10-14 15:58:08 +0200 | <tomsmeding> | ski: "not-necessarily-injective" -- ah! right |

| 2025-10-14 16:01:19 +0200 | <ski> | the "formal" here means that when we write a (finite) sum of products of monoid elements and associated coefficients, this is just a suggestive notation for having a function from the monoid elements to the coefficients, with "finite support" (meaning only finitely many monoid elements map to non-zero coefficients) |
| 2025-10-14 16:02:33 +0200 | <ski> | (iirc, in some rings, (ordinary) polynomials can be distinct (having distinct coefficients), while still having the same value at each possible input (being extensionally equal, the corresponding functions to the polynomials being equal)) |

| 2025-10-14 16:09:41 +0200 | <ski> | the direct sum case involves a function, with *finite support*, from the family indices to elements of the corresponding groups (monoids), while for direct product, it's arbitrary such functions. for arbitrary (not necessarily commutative/abelian) groups (monoids), though, the categorical coproduct case (called "free product") becomes a larger object. `g_0 * h * g_1' is no longer equal to `(g_0 * g_1) * h', |
| 2025-10-14 16:09:47 +0200 | <ski> | so you can no longer keep track of a single element per group (monoid)) |

| 2025-10-14 16:12:21 +0200 | <tomsmeding> | feels a bit far-fetched to me, not least because the result "invents new keys" that were not there in the original |

| 2025-10-14 16:13:30 +0200 | <tomsmeding> | yes, the other problem is that the maps get very big this way |

| 2025-10-14 16:13:43 +0200 | <tomsmeding> | that's not usually what you want in practice |
| 2025-10-14 16:14:01 +0200 | <ski> | unless the key monoid is highly non-injective, i guess |
| 2025-10-14 16:14:29 +0200 | <ski> | like, the keys are lists, bags, or sets ? |

| 2025-10-14 17:59:19 +0200 | <[exa]> | Tri: like, you can put literal && in between the conditions, I used a list because it formats nicely if you have many conditions |
| 2025-10-14 17:59:43 +0200 | <geekosaur> | Alternative only requires Applicative, not Monad |
