@imikotoba @Edent But seeing now that Kobo sells DRM-free eBooks from Tor Publishing and "standard" Adobe DRM from other publishers, so I don't need one of their e-readers, Kobo also looks good.

Woo! It's now official

I'm getting some grant funding to further develop #ActivityBot.

@Edent congratulations! I like what you have done with the AGENTS.md file

I'm going to try and keep a record of all the bugs, errors, and inconsistencies I've reported in #ActivityPub and #Mastodon documentation.

First up, how big are the limits on what you can federate?

Mastodon lists some limits in KB/MB, but others are just raw numbers. That might make sense for an ASCII world - but emoji complicate everything.

https://github.com/mastodon/mastodon/issues/40290

Documentation: Federation size limits don't show units · Issue #40290 · mastodon/mastodon

The FEDERATION document lists various size limits, but doesn't always explain what units they use. For example: mastodon/FEDERATION.md Lines 84 to 90 in 47ac677 | Limited property | Size limit | Consequence of exceeding the limit | | ---...

Next is slightly more trivial - a broken internal link in the Mastodon documentation.

Schema link broken - should be relative · Issue #1947 · mastodon/documentation

The documentation at https://docs.joinmastodon.org/spec/activitypub/#PropertyValue says: As noted above while listing the schema.org @context extensions, Mastodon currently incorrectly expects and maps the term […] However, that link goe...

I think the #RFC9421 HTTP Signature algorithm should be explicitly included in #Mastodon's requests.

Feedback welcome - especially those explaining politely why I'm a wrong about this.

Moving signatures to the standard (RFC 9421)? · Issue #29905 · mastodon/mastodon

Pitch There is now an Internet standard for HTTP signatures, RFC 9421. As far as I know (but I read the last versions of the draft too quickly), they are different from the signatures used by Mastodon. COuld it be a good idea to move to ...

@Edent Currently on vacation so I might misremember, but afair the algorithm is already determined by the key used. So including it would do no harm, but is kind of redundant.

@dave I'm not sure I understand.
The *digest* says what algorithm it uses, but it isn't a given that the same algo will be used for the signature, right?

I can't find another reference to the algorithm in the public key.

Very happy to be told I'm missing something obvious

@Edent RFC9421 only lists a handful of possible algorithms. IIRC if your key is ed25519 only one of them applies, similarly if the key is ecdsa. I think there are two possibilities for RSA keys, but we only support one for legacy reasons and do not plan to encourage future use of RSA so will likely never implement the other. So in practice looking at the key type should be sufficient to determine the algorithm used.
