If you are working on Fediverse software, I highly recommend applying for the NLNet Open Social fund. They have 480K euros to apply to ActivityPub software. The deadline is March 31st.

I'm looking forward to the #Fediforum "Growing the Open Social Web" workshop on Monday.

I'm extremely dubious about a lot of the submissions. There are a lot of untested hypotheses in this list:

https://fediforum.org/2026-03-growing-open-social-web/summary/

I hope that people's expectations are geared towards experimentation, data collection, and iteration, rather than confirming some of these assumptions.

So, one thing I said at #FediMTL yesterday is that Fediverse software should ship with the IFTAS DNI list as the default, minimum blocklist. Ideally, the list should periodically auto-update.

If you *want* to see gore, racist harassment, or transphobia, you can consciously remove those sites from your blocklist. If you want to subscribe to a different blocklist, you should get to do that, too.

Fediverse admins shouldn't have to learn how to find the DNI list and install it the hard way.

As is probably clear from the last 12 hours of active conversation on the thread you started, you've got an audience and a network that really brings people together.

I wonder, how comfortable you are using that convening power more often? As in, when are we having the WeDistribute conference? 😉

@steve@social.technoetic.com @smallcircles@social.coop

That said, I think it would be great to have reverse chronological ordered collections of objects created by the actor.

It would be nice to use streams like endpoints, as an object, and define properties like notes, images, places and so on off of it.

Unfortunately the loose definition and lack of examples for streams makes it hard to use. It’s probably better just to define them as top-level properties of the actor.

@virtuous_sloth@cosocial.ca It's usually correct. A lot of Fediverse servers use CORS or authenticated fetch to prevent loading the data directly into the browser. I feel like you're getting very particular about how it's implemented, which is fine. If that's important to you, express why and how it affects your answer in a reply.

One of the things as a software developer I have a hard time reconciling is how much people think that an app lives entirely on their phone. Like, LinkedIn is an app, and all of the infrastructure is inside it, and maybe all of the people live in there too? And if you delete the app from your phone, all the infrastructure and people and technology fall screaming into the void?

@steve@social.technoetic.com This is really interesting. I see a few cases. One is an ActivityPub API façade for an existing CMS, like Drupal or WordPress. The underlying system only stores Articles, so it tries to fit any input into that format. It might also take a Create/Image and return an Article with an embedded image, say.

@Gargron@mastodon.social since November there has been after-the-fact analysis that wonders how the Harris team could have won by throwing one group or another under the bus and thus picking up some slice of Trump voters. Not only is it grossly immoral, but it probably wouldn't have worked. Trump voters weren't looking for half-hearted Democratic attacks when they had the real thing on the other side.

@virtuous_sloth@cosocial.ca Yeah, it’s a perfect storm of protocol problems!

We don’t define what to do when an account is deleted, so this is kind of ad hoc to begin with.
We don’t define (many) error codes and what to do when they happen.
We don’t define how the encryption keys work.
We don’t define a way to use a different encryption key.

It’s all worth putting on the list of things to do for the next version of AP.

@virtuous_sloth@cosocial.ca it's a quirk in ActivityPub. When a user account is deleted, their server sends a user deletion notification to their contacts. But to confirm the authenticity, the receiving server has to fetch the sender's cryptographic key... which has also been deleted! It's possible to make some guesses here, but it's a pain and most receiving servers will just return an error. Unfortunately, the sending server will just keep sending the deletion notification. https://swicg.github.io/activitypub-http-signature/#handling-deletes-of-actors
