I wrote an article to clarify some of the terminology in the #ActivityPub specification related to collections, streams and HTTP endpoints.

https://www.stevebate.net/activitypub-note-streams-collections-and-endpoints/

Working on a FediHood-inspired "Nearby" feature for Catodon. Since FediHood's development has halted, I'm using it as a base, but without being restricted by it. I'm trying to build this not only thinking of Catodon's implementation, but with fedi on my mind, since we don't have a standard for location, and it could be useful for a lot of cases (events, marketplaces - even a federated dating app could use something like this, why not). So once I'm done, I'll propose two FEPs, so that other projects can also build on this.
#catodon #fedihood #fediverse #activitypub #fep

#Smithereen 1.1 is out!

In this update:
- Full-text search on walls, in group discussion boards, and in private messages
- Mastodon-like fetching of all comments for remote posts when you open them
- Moderation improvements: better domain blocks, bulk actions on users
- Support for making posts from external share buttons (FEP-3b86)
- As usual, way too many minor improvements and bug fixes

#ActivityPub #mastodev

So when I added support for Loops to https://columnly.social, I had to refactor quite a bit to abstract MastoAPI routes and entities properly.

Not only did that open the door to supporting other software more properly, but also inspired me to look into ATProto support so you could combine all your social web accounts in one beautiful client.

No promises, but I do look forward to implementing this when I have time!

Yonder — a self-hosted, federated social network in a single binary

Yonder is a Mastodon-compatible ActivityPub server written in Rust.
Your community, your rules, your data — and the Mastodon apps you already use just work.

I notice most people name their #Wordpress blog's #ActivityPub handle as @blog ..

With tons of blogs with the same handle prefixes this makes your blog hard to mention, and people have to remember and type the full #fediverse handle before it shows up in the account dropdown dialog of the post editor. Just saying.

@L29Ah
Не могу ответить на твой вопрос, потому что я его не вижу под моим постом. Федерация такая федерация в этих ваших федиверсах.

지난 몇 번의 일본 여행에서 이 책을 구하려고 했었다. 이번 여행에서 드디어 손에 넣었다.

Fedify를 만든 @hongminhee 님이 직접 쓴, @fedify 로 ActivityPub 마이크로블로그를 처음부터 만들어 보는 입니다서(『실천 Fedify』, 일본어).

한 손이 파란색과 흰색 표지의 페이퍼백 책을 들어 보이고 있다. 표지에는 커다란 로마자 글씨와 일본어 글씨가 있으며, 그 아래에는 동물 귀가 달린 교복 차림의 소녀와 만화풍 개, 작은 파란색 공룡을 그린 애니메이션풍 삽화가 있다. 뒤편에는 유리로 된 고층 사무실 건물들이 빽빽한 녹지로 둘러싸인 운하 너머로 솟아 있고, 운하 옆으로는 고가 철도가 지나간다. 하늘은 푸르고 흰 구름이 길게 뻗어 있으며, 화면 오른쪽 아래에는 반점 무늬의 화강암 난간이 자리한다.

🔄 The move from @fabio has been completed.

All followers (and even posts and replies) have successfully been exported to this account.

This account runs on #Yonder, a #Rust Mastodon-compatible #ActivityPub clone I built after getting too frustrated with the features of both Mastodon and Akkoma 🙂

I wrote another FEP, this time for C2PA ✨

I've just pushed ton of fixes for Libervia, the code is nearly good for alpha release. ActivityPub Gateway is fixed and doc is fully updated (on repos, not on official website yet), Audio/Video component has been updated to follow new spec, lot of work on web frontend.

You can try web frontend with this one-liner:
`uvx --python 3.13 'libervia-web @ git+https://www.goffi.org/forge/goffi/libervia-web/' local`

I should update official website soon.

📢 Account move notification

Almost everything is ready to move my social home to @fabio (@fabio@manganiello.tech).

The new account runs on #Yonder.

Yonder is a social platform I’ve been working on for a while, and I’ll soon write about it more in detail.

It’s an #ActivityPub server written in #Rust and fully compatible with Mastodon and Pleroma/Akkoma, plus with other #Indieweb features I like (support for #Webmentions, and #OpenID coming soon).

Plus it implements features (like on-demand remote fetch of statuses/threads context, support for Threadiverse-like actors, OAuth-based account migration that also includes posts and interactions without needing to move CSV files around, better storage management…) that I’ve wanted in those platforms for a while but I’ve struggled to get merged.

If you follow me here, you can hit the follow button on the new account (and if you don’t, don’t worry, my followers will be migrated at some point between today and tomorrow).

The story of Linux should inspire the Fediverse.

"The year of the Linux desktop" has been a joke for 25 years - a quarter of the century! Yet slowly, and with a persistent following building for linux and supporting it, it's reaching a point where it's no longer something to laugh about - it's a valid choice for many people. Hell, my father (who is 81!) uses ZorinOS, which I installed when windows became too laggy and frustrating for him on his aging PC.

Similarly, if you tell someone that fedi can replace facebook/instagram/x for them, they will probably not take you seriously - most of the people they want to interact with are not here. In the very same way that the apps that people wanted to use on their operating system were not on linux some years ago. Things change - we can change them!

Linux is 35 years old. ActivityPub is less than 10!

Let's build apps and communities for the widespread adoption of the open web, for the fedi revolution. This won't come by itself, we have to prepare it. But we will - we already are!

#fediverse #activitypub #linux

My perspectives on the Fediverse protocol and its relationship to #ActivityPub....

https://www.stevebate.net/the-fediverse-is-not-activitypub/

@colinstu In fact , a lot of blind, colorblind and other disabled people needed the new UI to better navigate mastodon.

Also all improvement, features and so on requires to be usable within the #activitypub protocol or else they would just create a greater rifts between mastodon and others softwares.

I won't put up the amount of works require to put "simples ideas" into a software because I really can't list them all .

Mastodon is also open source , I get that ruby and Ruby on rails aren't that simple to learn but I guess you have coding experience to be able to say why and why not the project is moving in a good direction.

I mean nobody without any skill in drawing would go to an artist and tell them they're sketch are not good.

Wonder why a lot of people's does this with open source dev

Short-form video, photo and blogging platforms commonly let creators publish one post together.

So we built this feature into Loops, with consent based ActivityPub support, and a FEP.

Shipping soon!

Loops Collaborations feature

Quote-posting your own posts is now allowed (do it by adding RE: https://example.com/you/post-id in its own line in a post body).

The Mastodon API can now be disabled by setting the mastodon_api directive to false in server.json (no need to compile it out).

Fixed a crash in chunked transfer encoding code (special thanks to Sergey Bronnikov for bringing this to my attention).

Tweak to JSON loading code to circunvent fmemopen() issues on Illumos / OpenIndiana systems (contributed by aleteoryx).

Mastodon API: Fixed error in voting code (contributed by uilebheist), more aggressive old data purging.

Check out Columnly – a multi-column client for all your ActivityPub-based accounts! 📊

Manage all your feeds in one place with a clean, customizable layout. The only feature really missing right now is automatic system light/dark mode support.

Why, Mastodon? Why?

Why are you forcing signed requests for all "Accept: application/json" HTTP requests of the actor URL? Rather than just actors that choose to be "private".

...

curl -H 'Accept: application/activity+json' https://mastodon.social/users/reiver

{"error":"Request not signed"}

#ActivityPub #Mastodon

Loops now supports RFC 9421 Http Signatures!

https://fedidb.com/software/finder?f=http-signatures-rfc9421

#loops #activityPub #rfc9421

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.
