I swore not to speak about #FediHood any more, but what #Pixelfed is doing is great news for #ActivityPub.
Pixelfed already sends the location as a Place object with latitude and longitude, so FediHood can read it and put markers on a map.
Local timelines used to mean one instance. Now they can mean people actually around you.

Places, a unique Pixelfed feature that allows you to add an optional location to your posts to make them discoverable by place!

We are working to support custom places too!

Sharkey is generally no longer actively maintained. Much like IceShrimp, which shifted its focus from IceShrimp-js to IceShrimp.net, Sharkey is effectively in "maintenance mode only." This means it still receives critical security updates and required patches, but it generally no longer tracks upstream Misskey development.

Sharkey's latest release: 2025.4.7

Misskey's latest release: 2026.9.0

I had to laugh when, back on January 13, 2026, they titled a release "2025.4.5 — We'll catch up, we promise." The release right before that had been 6 months earlier. In all the time since, they've only pushed out 2 security updates. They are now well over a year behind Misskey's development.

If anyone has the time and skills, I hope someone builds a script to migrate Sharkey sites back to Misskey. Since Sharkey is a fork of Misskey (as was FireFish), it should be possible and is a smart precaution.

🆕 blog! “Scattered thoughts on social geolocation”

I want to be able to share my location with my friends on social media. Twitter (RIP) had a way to attach an optional location to a post. Facebook still lets me check in to venues. But neither ActivityPub (Mastodon) nor AT Protocol (BlueSky) allow me …

Kind of a weird #Fediverse question: do any platforms in this space offer an API for user account registration?

One hypothetical idea I’ve been kicking around is the notion of “pre-registration” for the Fediverse. Basically, a person fills out their profile, imports data archives from other networks, and maybe even finds their mutuals somehow. When they’re done, their account gets created on a random vetted instance, data gets backfilled, and follow requests get sent out to the mutual contacts they’ve found.

I think it’s a good idea, and possibly a good showcase for both the #ActivityPub C2S API and possibly LOLA. However, I don’t think any particular platform supports all of the required pieces yet.

Alt...

A mockup of an app, showing my name and face, as well as different social networks to connect to for data import.

Next step in the mockup for a Facebook import, allowing me to pick and choose what data is most important to me.

Alt...

A final stage mockup showing a recommended server with its name, domain, and rules. Obviously needs a touch up, but the idea is that everything is spelled out to the person about where they're going.

Because we changed our domain, our #ActivityPub #ThreatIntel federation also changed! You can follow @threatintel for all posts in our forum's Threat Intel category.

The EFF is promoting the Fediverse in an online event next week!

Right after @berlinfediday is over, I am hosting another edition of
Berlin Federated Network Exploration Circle / #BFNEC
Sept 13th at 7pm at @offline

✸ @pukkamustard will talk about their work on ERIS and give us the backstory on their initiation of the fediverse's FEP process.

⁂ @f will discuss his work on @sutty, a platform aimed at giving organizations and collectives the means to publish and host more secure websites. He will also talk about how they recently added #ActivityPub federation.

Berlin Federated Network Exploration Circle a cosy meeting of humans who want to discuss this strange networked world together September 13th, 2026 (7pm) at Offline ✸ pukkamustard will talk about their work on ERIS and give us the backstory on their initiation of the fediverse's FEP process. ❋ f will discuss his work on Sutty, a platform aimed at giving organizations and collectives the means to publish and host more secure websites. He will also talk about how they recently added ActivityPub federation. ⁂

Public Messaging Platforms

‣ Simple: Plain old website with #RSS feeds

‣ Emergency Alerts: #CAP (Common Alerting Protocol) + delivery backends like #CellBroadcast

‣ Microblogging: #Mastodon (AP)

‣ Long form content: #WordPress + AP plugin

‣ Video hosting: #Peertube (AP)

Notes:
• AP: #ActivityPub
• This is only a small sample of the options available.
• These platforms are in use globally for this purpose.

For #ActivityPub applications people may refer to the three deligthful #fediverse curated lists I maintain. See the ToC in the top-level list at:

If you're reading this, you've probably been hitting your head against a brick wall trying to parse and decipher the new HTTP Signatures sent by Mastodon and other Fediverse servers.

Fixed a bug in the notification page that made snac hang forever while trying to read abnormally big files.

Improved support for text-only web browsers: it's now possible to configure a set of web browser user-agent strings that will receive simpler HTML in the private timeline web UI. Basically, it consists in avoiding details / summary HTML tags as much as possible.

Added some fixes to media proxy code.

Fixed EmojiReact code to allow any emoticon defined in emojis.json, not only those with colon-wrapped identifiers.

Fixed a bug in notification filtering (paging was sometimes incorrect).

Added a notification filter for Webmentions.

Mastodon API: Don't return reactions count as string (contributed by mkljczk), implemented GET /v1/media (contributed by clairemont).

Fixed bug in documentation examples (contributed by Sprite_tm).

Updated Ukrainian and Russian translations (contributed by wincentbalin and koru).

#FediHood now supports #Lemmy through #ActivityPub. You can subscribe/unsubscribe from groups, read threaded discussions with their upvote scores, and reply or upvote yourself (through the fav button).

This is the first step: FediHood will also automatically split messages into city, region and country groups that everyone on the fediverse using groups will be able to interact with.

I recently discovered that Jorge Aguilera (@jorge) gave a 1 hour introduction to #ActivityPub in Spanish called "ActivityPub: El Protocolo que Impulsa el Fediverso" at Commit Conf in Madrid and the whole thing was recorded:

Somewhere else, this is a patent fight. Here it's a GitHub issue.

https://github.com/pixelfed/starter-kits/issues/1

Almost 2 years ago I started planning federated Starter Kits. @Mastodon took the idea, turned it into a FEP, and built it with my feedback rather than around it.

It shipped in @loops this year. Mastodon shipped Featured Collections months later.

Compatible. Collaborative. Consent-driven 🚀

Name another photo app that will happily send you to a competitor.

If Pixelfed isn't for you, there are many amazing alternatives like:

- @frequency
- @gotosocial
- @admin
- @vernissage

All of them let you share images. All of them talk to Pixelfed. Leaving isn't a punishment here, because you never lose the network.

When you put people first, you build doors instead of cages.

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.

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.
