I'm curious whether anyone on #Mastodon can explain why this post https://mstd.seungjin.net/@theguardian/116535352864096634 is appearing in my feed many times over? I follow several Maths/education related #hashtags (via #relays ), and thought at first I was getting one through each #hashtag #relay (1 post each), but when it exceeded that I looked and in fact it only contains one hashtag I follow, so it's the same post over and over again, maybe a dozen times so far. Why is that happenning? #askFedi #federation #activityPub

Hi everybody — late last week we released v4.11.0, which contains the following changes:

ActivityPub Specific Fixes

AP analytics and error pages

New pages have been added to the control panel to display analytics (send/receive counts) and error counts. There is also a new error page that will show error received within the last 24 hours, and their respective payloads. This will aid in debugging federation issues.

Article vs. Note distinction updated

Prior to this version, NodeBB would determine whether a federated object was an Article or Note based on content length. This was confusing for end users, and was originally added before NodeBB supported title-less topics.

The revised distinction is much simpler. If it has a title, it's an Article. If it doesn't, it's a Note.

Smaller fixes

Threadiverse software publishes Delete objects wrapped in an Announce activity. This is how content is moderated across the threadiverse. NodeBB now supports this, although it has not been extensively tested at this time.
There was an interoperability issue with Mitra that was identified and fixed.
When group actors post content directly, the category info is shown in the user icon. It used to error out and show "Guest".
Optimized the outbound federation of content so the front-end is more responsive. A bunch of back-end optimizations to reduce the number of calculations needed.
Emojis now supported in DMs to remote users.

Ability to hide read notifications in user panel

A new option has been added to the "Notifications" sub-section of the user control panel.

This option will allow you to visibly hide read notifications from the notifications dropdown, which reduces visual clutter.

Tinycon customizations

Admins can now customize the notification badge shown in the browser tab icon. We use the Tinycon library for this, and the colour values can be customized now:

@rl_dane@polymaths.social

After having a post go "fedi-viral" (100+ boosts), I can better empathize with what @vkc and @TechConnectify have been complaining about WRT behavior on #fedi.

I've mostly gotten positive comments from people I already knew. One or two replies were a bit odd. One was seriously bonkers: bad enough to make me report, mute the entire instance, and block.

That's rare for me. I'm very much a live-and-let-live kind of guy (that's a privilege, I know), and I happily interact with people whom I disagree with sharply on some issues, and I have mutuals that honestly hate each others' guts. 😄

The #fediverse still has a moderation problem, and the fact that 99% of its users may not encounter it doesn't mean it's not there.

So thankful for the vigilant, too-often-thankless (or worse) work of instance admins and some of the more clever fedi clients in keeping the amount of craziness down.

I like the fact that @pachli has an option to warn or hide posts from new accounts. I think that should be a feature of all #fedi server software. I'd also like to see less of a trust-by-default model for federation. It would be neat to have some kind of a credit score for instances, and the ability to share those scores, such that a highly-rated instance rating another instance as being very poor would have a heavier weight than a new or poorly-rated instance giving that same instance a high rating.

All that is way beyond what #ActivityPub was intended to do initially, I'm sure. I'm hoping the fedi can grow towards being a safer place for all, and I'm certain that's what nearly everybody wants. It's just a question of how to do so. And that's not a five dollar question. ;)

#WhatsMissing: A #narrowband-friendly #ActivityPub #Client / #Server - System that allows people to #post and communicate even on extremely narrowband connections like #Iridium (espechally #ShortBurstData) and similar.
- Potentially even #AFSK over #CB-Radio, #LoRa, #Moonbounce'd comms and others... So way below #NBIoT bandwiths.

Basically something that could work within the few bytes of an #SBD transmission, using #TOTP with short TTL for authentification and is so brutally simple that one could manually send/recieve messages/posts with #curl (or #wget) and even support "#legacy" systems without a #proxy like #FrogFind in between (tho that is also an option)...

A bit like #ntfy in terms of simplicity.
- With like a simple, short message:
```
curl -d "test message" domain.example/@xsample&totp=1234567890
```
Which comes out to 62 Bytes or 9,45¢ [U$D] in costs over #IridiumSBD. [excl. baseline fees]...

I (Evan) will be at the Wikimedia Hackathon 2026 in Milan, Italy this weekend (May 1-4). I’m especially interested in how we can connect Wikimedia projects and content to the Social Web using ActivityPub. I’ll be holding a session on the topic on Sunday May 3 at 9AM, but I’ll also be available for discussions throughout the weekend.

My hacking project plan is to make an ActivityPub object server for films. There are about 343,000 films in Wikidata, which compares pretty favourably with the 740,000 films in IMDB. There is a JSON-LD interface to Wikidata, but the types used don’t match up with ActivityPub types like Video. So, like places.pub, I’ll set up movies.pub to share an ActivityPub object for every Q-item for a movie, as well as a search endpoint to find films by name.

If I get ahead of the project and I’m not too jet-lagged, I’d like to add an ActivityPub API app to “check in” to a movie that you’re watching (and maybe give a little review). Similar to checkin.swf.pub with places!

If you’re at #wmhack this weekend, please come say hi. I love talking about Wikimedia projects and the open social web.

What should the file-extension for ActivityPub / ActivityStreams documents be?

I.e., for application/activity+json data?

I've been using .activity

Ex: filename.activity

(The extension cannot be .json or .jsonld if you want to be able to detect it just based on the file-extension.)

What do you think?

I'm glad to announce the release of version 2.78 of #snac, the simple, minimalistic #ActivityPub instance server written in C. It includes the following changes:

Hashtag following also allow URLs to RSS feeds of ActivityPub objects (like e.g. https://mastodon.social/tags/ThankYouTuesday).

Users can now configure a webhook to receive an HTTP POST for every notification. This can be useful for implementing bots that react to activities, like autorepliers, chatbots or interactive textual games (see snac(1) for more information).

The number of pending follow confirmations is shown next to the "people" link.

Faster performance metrics (contributed by dandelions).

Improved lowercasing in hashtags (contributed by postscriptum).

A search-by-url tweak for implementations that return 200 for invalid webfinger queries (e.g. piefed).

Mastodon API: added follow confirmation endpoints, fixed collisions in attachment file names.

Fixed potential crashes in attachment uploads.

#Elgg is getting an #ActivityPub plugin!

Now if you’re not familiar with Elgg, it’s one of the first ever open source social media platforms. It launched all the way back in 2004 and was founded by @ben and Dave Tosh.

I remember installing Elgg 15 years ago, playing around with it for a bit, and not doing much with it because there wasn’t anyone I knew who used it. So ActivityPub will definitely extend its network effect.

Notifications are now shown in a more compact way (i.e. all reactions are shown just above your post, instead of repeating the post ad nauseam for every reaction).

New command-line option unmute to, well, no-longer-mute an actor.

The private timeline now includes an approximate mark between new posts and "already seen" ones.

Fixed a spurious 404 error in the instance root URL for some configurations.
