@benpate@mastodon.social talking about the toggle button in bandwagon to share stuff to Bluesky, and how others should make AP integration as simple.

@benpate@mastodon.social preparing for the next talk

I went to get a cup of coffee and came back to @garbados@hey.hagelb.org talking about how we don't need more toilet spikes.

I was told that I should just watch the recording

@matt@writing.exchange showing the difference in non-Note support then (pre-2025), and now (2026)

@matt@writing.exchange's demo account is going more viral than expected. > 1k views and 9 boosts. @fedicon@pen.writefree.ly

@evan@cosocial.ca "if the Fediverse is about connecting people to people, then Ostatus is part of the Fediverse. However usage has been dropping off.

...

Philosophically yes, practically, heading towards no"

@liaizon@social.wake.st

@evan@cosocial.ca explaining that "the fediverse is quiet" is a bug, not a feature.

Good thing we have a solution for it

AP devs, fixing AP paper cuts one at a time

In response to the question "what should the Fediverse not be?"

@ozoned@btfree.social warning against turning it back into walled gardens.

The panelists now asked which default server they'd recommend. These questions are hard!

Even @ozoned@btfree.social wasn't sure prior to the panel.

@evan@cosocial.ca suggesting that maybe you already have one and don't know; suggests checking your orgs and associations; possibly self-hosting or checking joinmastodon.org

@django@social.coop warns about checking Instance rules to align on values.

@ozoned@btfree.social suggesting Mastodon for twitter fans, Pixelfed for Instagram fans, forums for topical based discussions (plus a shoutout for ActivityPub.Space, thanks!)

I did not know that @django@social.coop was based in Edmonton!

The contingent of Canadian AP developers continues to grow... No wonder all of the Fediverse conferences in the Americas are in Canada

Q: "is Truth Social on the Fediverse?"

Now @ozoned@btfree.social explaining (very carefully) that Truth Social is built on the Mastodon codebase but functions like an island. It does not federate.

Q: "is BlueSky on the Fediverse?"

@reiver@mastodon.social "Evan why don't you take this one"

First up, the panellists are asked to describe the fediverse in 6 words or less glad I'm not up there!

@django@social.coop says "when big social blows up, confettiverse" (apologies if I quoted it wrong!)

Day 3 of FOSSY aka Day 2 of FediCon starts with a panel featuring @evan@cosocial.ca @reiver@mastodon.social @django@social.coop and @ozoned@btfree.social!

@skavish@welley.social argues private communities should not be federating content outward, just granting access.

FediCon/FOSSY 2026 Live Thread

This is the beginning of the live thread for FediCon/FOSSY 2026. Check back here for updates regarding the Fediverse track of FOSSY (Friday and Saturday).

Tagging @j12t@j12t.social as this might be something worth discussing in relation to activitypub.rocks

Reflecting on the existence of httpsig.org

httpsig.org is a site with one sole purpose, to advocate for the adoption of RFC 9421 HTTP Signatures. It has a "Libraries" tab that does exactly what it advertises, it lists a bunch of libraries for you to use so you don't have to roll your own.

If you want to integrate AP today, but you don't want to roll your own everything, where do you go? Who do you ask?

All I know is:

• Fedify → Typescript (thanks @hongminhee@hollo.social!)
• FedBOX → Go (thanks @mariusor@metalhead.club!)[...]

Do we even have a list sorted by language? This would be huge. What other AP frameworks do you know of?

Granted, I didn't do a lot of thinking and deep diving before I listed those two examples, but even then, that's 1 more example than is listed on https://activitypub.rocks, so I think I might be on to something here from a developer advocacy point of view.

If I were looking to integrate AP, one of the first conclusions I'd come to is that the protocol itself is fairly complex and a library or framework might help.

I don't think there is a list that plainly lists supported libraries by language.

Edge case when backfilling topics

When it comes to backfilling topics, NodeBB utilises what is called "context collection backfill" instead of reply-chain traversal. In a nutshell, instead of crawling up and down the reply tree one-by-one — kind of like what Mastodon does currently — it checks for a canonical source-of-truth in the context property.

NodeBB supports both strategies, since not all objects contain context.

I found a fun little edge case where if I start a topic, a reply is received, and that reply points to my instance, it won't catch any replies made in between.[...]

In other words:

localA starts topic → remoteB replies → remoteC replies to B only → remoteB replies to C and A

In this scenario, because my instance A is left out of the third activity, I don't know about it. When the fourth activity appears, the context is checked, C's reply isn't in it, and I proceed without knowing about it. Oops!

In this case, when incoming replies reference a context that is same-origin to your own instance, you should not use context collection backfill, because:

1. You already have the entire context, so it's unnecessarily duplication of work
2. You won't catch any replies made out-of-band unless you do reply-tree traversal

Tagging @silverpill@mitra.social because this is related to FEP f228.
