RE: https://mastodon.social/@Edent/117064015037748440

This is a real problem which I totally get and analogous to how I use favourites on Mastodon(which I fon't go back very often unless they're recent ones)
Thinking about it I now want an ActivityPub server I can store these to, whike adding tabs, and a browser plugin to post to it ...

How do you deal with all your open tabs?

I have a hundred "I'll look at that soon" tabs across three devices.

Does anyone here use an (open source preferable) app for keeping track of all the things they want to get back to?

They're not all articles, some are searches, IMDb pages, etc. So I dont think Wallabag will work (correct me if I'm wrong though).

Any help to tame the madness appreciated 😄

(Looking for personal recommendations. I know how to search the web.)

I have made a pretty interesting discovery on #Peertube. You are able to follow the peertube instances itself as an user on Mastodon.
(Speculation)
When follow an user from a Peertube platform, only the videos of the account you follow display on your mastodon instance. Differently from mastodon(and others) that when you follow an user in an instance, all the post form the instance get displayed from now on.

Hey theATL.social 👋

Thanks to your suggestions, we now have a new service: #WriteFreely , a publishing/blogging platform that runs on #ActivityPub.

This new service is available at https://write.theatl.social - users at any membership level may now create a blog.

Logging in is easy: your existing theATL.social Mastodon account logs you in.

I've (publicly) forked the WriteFreely repo to continue developing on additional features...first of which is easy adding of pictures and other media. I'm open to suggestions as to what should be worked on next.

More thoughts in the thread 🧵

#Bluesky, a #decentralised #socialnetwork, is experiencing a #decline in #activeusers despite its initial post-election surge. While the company is shifting focus from the app to the underlying protocol (AT Proto), which powers other social apps and services, the decline in app usage suggests a challenge in retaining users. Meanwhile, #Threads, a #Meta owned app, is seeing significant growth in #dailyactiveusers and website visits. https://techcrunch.com/2026/08/11/blueskys-active-user-base-is-shrinking-as-its-focus-expands-beyond-the-app/?Fedizen.EU #Fedizen #Fediverse #ActivityPub #News

My advice to new activitypub devs:

- be bold: ship what big tech won't.
- consent first: opt in, never opt out.
- keep evolving: your v1 federation code will be wrong, and that's fine.
- federate the future: interop over lock in, every time.

8 years in and I still come back to these.

I was really happy to see @benpate and @dansup exploring similar ideas at the last FediCon: reducing user friction and making onboarding to the Fediverse almost invisible.

I’ve been working along the same lines. Here’s a small example: a user can interact with a #BadgeFed instance by simply logging in with #LinkedIn or #GitHub.

They can comment, upload images, like, boost, etc. They don’t need to know what the Fediverse is, what an instance is, or what software is running underneath.

For them, it’s just a social app.

Of course, existing Fediverse users can still connect with their Mastodon account or use their preferred Fediverse software.

Under the hood, it’s a #GoToSocial account configured with LinkedIn/GitHub OIDC OAuth.

But to the user? Completely transparent.

I think this kind of invisible complexity is one of the ways we can make the Fediverse much more approachable without sacrificing interoperability.

I submitted a Pull Request to update MacPorts' snac to 2.94 and thanks to Herby Gillot that was merged here:

https://github.com/macports/macports-ports/pull/33979

My apologies for the delay! Though I check repology.org with some frequency (usually several times on any given day) it didn't seem to pick up that snac was behind upstream. Good thing I thought to check the Codeberg repository independently I guess!

A quick #introduction: hcxp is soon to be released independent and open hardcore punk events and posters directory.

Anyone can add, anyone can suggest changes and anyone can browse events/flyers for any place in the world - all connected to the #fediverse! So you can interact from here, follow your city profile for updates and what not.

@mooooooo I think @mapache has implemented #ActivityPub on #DotNet? Maho, would you mind giving this team a review or some tips?

#ActivityPub people, we're failing at implementing the HTTP signatures necessary for interop, does anyone know how one would do this in #AspNet #dotnet 8?

Otherwise, could you check what's wrong with our implementation by looking at an example request, to see if anything jumps out?

Totally understand that troubleshooting and bughunting is work, I wish we could pay for this. Drop any donation/tip page you have and we'll try to donate what we can when we can <3

TIL #Pleroma is the most open and honest #ActivityPub implementation when it comes to things your server may lack for interoperability. Everyone else will just cross their arms at your messages and go "401" but Pleroma will say "your HTTP signature is malformed in this specific way"

#FediHood should be easy to use, with a very simple interface. It fully uses #ActivityPub and is compatible with the #Mastodon API (tested with #Fedilab). It will of course bring extra endpoints related to how it works. The project reuses the combined work from #HolosSocial and #PawFed.

Here are some screenshots of the Web UI.

FediHood's map set to an 8 km radius: an interactive map showing two count badges, each marking how many people are in that spot.

FediHood's Nearby feed: a distance slider set to 10 km, then a few posts from people close by, each with a time, a city, a distance and a topic tag such as Sport or Events.

FediHood's compose screen: a large message box, then four options: Visibility (who can see the post), Reach (how far it shows in Discover), Topic (its category) and Language (what you write in), plus Add image and Publish buttons.

The topic list in FediHood: Chat, Meet people, Events, Help, Buy & sell, Transport, Local news, Politics, Sport and Culture.

Great day at #Fedicon yesterday. I met lots of new people from the #ActivityPub community. I've always thought that #XMPP and the #Fediverse are ideologically well-aligned, and that our developer communities should talk to each other more. In that regard, it was a big success.

Stefano Marinelli (creator of the excellent FediMeteo) is working on a new type of lightweight Fediverse server called "littleFedi".

It's still in its early days and under development, but the first test server is now open and Stefano is gathering feedback about it.

Okay, so

https://docs.joinmastodon.org/spec/security/

According to resources linked in the #Mastodon docs, it seems that signature validation gets the entire #ActivityPub Actor (thus the `#main-key` which the server is supposed to ignore) and then within the Actor it gets the `publicKey` property.

Soooo back to the `#main-key` nomenclature, I guess

#snac2 #fediverse #frugalfediverse

The author of a replied post is no longer added to the CC: line, as it does not have much sense.

Fixed mentions for users with hyphens in their identifiers.

Unlisted replies to unknown posts were being skipped from the timeline, so don't do that.

If an actor marked as broken gets a post boosted (proving that is [back] functioning), it's unmarked as such.

Don't try (and fail) to parse non-UTC dates in posts (I'll provide a real fix eventually).

Fixed a redirection loop in the /users alias.

Mastodon API: fixed a bug that made changing the sensitive content string impossible, avatars and headers can be deleted (contributed by bm90).

Updated Czech and Italian translations (contributed by pmjv and fidiben).

I migrated from my self-hosted Mastodon instance to mastodon.social. Of course, I couldn't move my posts so I created a small server to provide the archive of my post history without changing any #ActivityPub URIs or media URLs. It seems to be working well. RAM usage is down from 1.2GB to 45MB (-97%) and disk usage down from 160GB to 15MB (-99.99% drop) compared to keeping the old server running. I've been surprised how many "hits" I'm seeing for old posts, so I'm glad the archive is available.

Turns out, #Mastodon 's implementation of #ActivityPub just has eveything in a Note's content and contentMap be HTML, so Markdown gets transcribed into <h*>, <strong>, <em>, <code>, etc.

But also, OPTIONALLY, some of those HTML Note also have a mediaType property with value "text/html" so maybe you can make an untranscribed markdown Note if you specify "text/markdown" maybe?

Inconclusive.

If you're into photography, there is a free open Flickr-style photography platform which you can host yourself called Vernissage. It also has Fediverse compatibility so people can follow Vernissage accounts from Mastodon, Pixelfed etc. More info at:

I added a list of recommended libraries to the ActivityPub developer guide:

https://codeberg.org/ap-next/ap-next/src/branch/main/guide.md#libraries

- activity (Go, used in GoToSocial)
- Fedify (JavaScript, used in Hollo and Ghost)
- Fedipub (Ruby, used in Manyfold)
- activitypub_federation (Rust, used in Lemmy)
- APx (Rust, used in Mitra)

This list only includes libraries that are actually used somewhere. Libraries that are not used, or used in projects with too few users are not included.

#fedidev #activitypub

Welcome to Prismo revived!

Not so long ago, after a bit of encouraging from @dansup, I decided to revive this project using more modern stack. Apart from it being more modern, it is also way lighter than before and that's my main goal when working on it: everything should be as simple, light and independent as possible.

Technical stuff

New Prismo only depends on Ruby and sqlite. JS layer is minimal and based on importmaps so no heavy build step is needed anymore. CSS is being generated by native tailwind binary so produced stylesheet files are as small as possible and generation footprint is tiny.

When it comes to federation, old Prismo was based on a code extracted from Mastodon which was both messy and far from optimal to be used by such a small and simple website. Now we're using an excellent ruby library called Fedipub instead.

Why another link aggregator?

While other projects are focused on supporting multiple groups with massive amount of people in them, Prismo is more about small cozy federated single-topic instances. Being small and simple will let us perfect our feature set more easily.

What's next?

There is no any roadmap as of yet but, for starters, i will try to bring back original feature set (as you might feel like new Prismo is a downgrade from the old one - i just brought back the essentials for now). After that - we can discuss on what's needed and what would be good to have :)

There are obviously plenty of rough edges and issues but we will get there eventually. Let me know in the comments and, as usual, boosts highly welcome! :)

Let's talk!

• Mastodon
• Matrix

The network effect is crucial to every social platform, and what differentiates them is how they are able to match IRL connections with online ones, and we can do this, but it needs to be done carefully and in a way that preserves privacy and user autonomy across platforms and services.

No single software should have the ability to wall off access, or we become the thing we worked so hard to replace.

More details soon 👀

#ActivityPub #Discovery #FriendFinder

One boost.

40k followers.

Thousands of individual HTTP requests, each one signed, each one a fresh connection, each one saying hey to a server it talked to four milliseconds ago.

Mastodon, Pixelfed and Loops do better than most here.

We can still do significantly better.

What if two servers just... stayed on the line?

More details soon.

#ActivityPub

@dansup

A good feeling, hopefully?

#ActivityPub #SocialWeb #Fediverse #AtProto

In 1968 Dijkstra declared GOTO statements harmful.

In 2021 someone built them an entire social network anyway.

GotoSocial is a lightweight #ActivityPub server that can run on a potato, blocks scrapers by default, and with privacy defaults that would get a product manager fired at any real company.

Now it's one of the fastest growing on the fediverse.

Built by @dumpsterqueer under the name Super Serious Business, which is the most honest branding in tech right now.

https://gotosocial.org

It's a strange feeling, building something with no one to answer to but the people using it.

No walls to raise. No data to harvest. No quarter to hit.

Just a network of communities that actually belong to the people in them.

#Loops has entered #beta with #ActivityPub support, allowing users to connect with creators across the #fediverse. This means users can follow and interact with creators on platforms like #Mastodon and #Pixelfed, and vice versa. Loops has implemented several technical features to ensure smooth federation, including a shared inbox, HTTP signatures, and smart content representation. https://blog.joinloops.org/loops-joins-the-fediverse/?Fedizen.EU #Fedizen #Fediverse #ActivityPub #News

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.
