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

Snac is a lightweight Fediverse-compatible social network server which is entirely human-written, and doesn't require a database. You can find out more at:

🏡 https://codeberg.org/grunfink/snac2

You can follow Snac's lead developer at:

🏡 @grunfink

It can be installed via @yunohost (at https://apps.yunohost.org/app/snac) or manually using the installation instructions (at https://codeberg.org/grunfink/snac2/src/branch/master/README.md).

Looking for these kinds of accounts to follow to keep informed on software and papers:

1. ActivityPub and Fediverse hosters and software developers.
2. Secure communication hosters and software developers.
3. Usenet / NNTP hosters and software developers.
4. Cryptographers, cryptanalysts, cipher code makers and breakers.
5. Writers of papers and preprints.
6. Textual Criticism buffs and translators, including producers of papers and software.

I don't pretend to know the tech details of it, but being #ActivityPub" alone means nothing

I visit dozens of ActivityPub instances ever day and I never get auto-logged-in to any of them because I don't have registered profiles on them

It might be *possible* but Gargron has certainly not *done* it there...

(Using alt acct for higher character limit)

By the way, what do you mean by

I don't know how or why I have an account here

Do you mean an account on the Threadiverse (Reddit-like systems with threaded conversations in topic-based communities: Piefed, Lemmy, Mbin), or even specifically the Film Frames community on Lemmy.World?

You don't actually need a threadiverse account to see threadiverse posts on Mastodon. (Just one of the ways the different parts of the Fediverse interact through the ActivityPub protocol.)

Threadiverse posts with hashtags will appear on Mastodon, & you'll see them if you follow the hashtag or that threadiverse user (or if a Mastodon account you follow boosts the post). (I don't know if a Mastodon account can "follow" a threadiverse community the way you can follow a hashtag.)

Mastodon users can make posts that will also appear in a threadiverse community but only if formatted in a specific way. But I can never remember how to do it 😅 I think it involves:

• writing the community's name as if it were an account name (e.g. ATfilmframesATlemmyDOTworld).
• making a 1st paragraph of only one sentence which can serve as the post title (a threadiverse requirement).

As I already have Piefed & Lemmy accounts, I just use Piefed & make a post with hashtags if I want a post to be visible on both the threadiverse AND Mastodon. (Mbin is another option, a system designed to blend together both the threadiverse & the "blognetworkverse"(?)(Mastodon, GoToSocial etc))

Introducing Creator Collabs, a new Loops feature that allows two accounts to coauthor the same video!

Demo: https://loops.video/v/j2TFb-rai6

ActivityPub: https://fedidb.com/tools/pub?q=https://loops.video/v/j2TFb-rai6&tab=json&explain=0

FEP: https://codeberg.org/fediverse/fep/src/commit/1eb98facf45ab0ff95598338e0fb61c14b29a667/fep/336f/fep-336f.md

#Loops #ActivityPub #CreatorCollabs

I see a way to improve activitypub. Build an extension that does not require servers. Instead it would use servers for discovery of running clients.

Everything else would stay the same except clients can identify by a public key hash instead of domain name.

This would allow single-user local clients to sync directly or through a instance relay with other local clients when they are online, as well as with public domain-based instances. All posts, media and objects could be stored locally as files instead of using a database engine. This would also make it simple to run clients over TOR.

Think about it.

It would blow NOSTR out of the pond.

The obstacle to this is the mandatory HTTPS requiring use of certificate authorities. The client-only version would have to drop this and use public key of user accounts to secure transfers.

Also thanks to Sergey Bronnikov, aleteoryx, uilebheist and anyone else who may have contributed to this release whom I may have inadvertently omitted.

I submitted the following Pull Request to update MacPorts' snac to 2.97 here:

https://github.com/macports/macports-ports/pull/36231

Which, whoa, was merged before I even completed typing this post thanks to Herby Gillot!

My apologies for the delay in submitting the PR. I did see a new version was released yesterday while I was doing laundry; yet I was super tired after the Pixel Grip show on Wednesday (I barely caught the last BART to the East Bay Thursday morning, worked earlier on Thursday and had to be awake before dawn for two shifts today so I was in bed early and woke up early and am just now getting around to this.)

Does anyone on here have any experience with or advice on using Peertube? I'm thinking of considering recommending it to a local community group for hosting their videos in a non-commercial space, but they don't really have the means or capacity for self-hosting. Is joining an existing Peertube instance a viable option?

#Fediverse #Peertube #ActivityPub

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!

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.

Here's a throwback. I found a dir with a bunch of pictures of #rstatus (formerly, https://rstat.us) circa October 23, 2011. They're all just the front page, but in different browsers on different OSes.

rstat.us on October 23, 2011, rendered in Mozilla Firefox on Windows Vista. A gray bar, a turquoise bar, then white and gray. A bunch of random icons and some posts on the left.

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".

Wouldn't it be cool if fediverse clients had a well structured `.well-known/activitypub-client-config` document to make building apps less painful?

Upload limits, composer limits, account limits. Software neutral, versioned, extensible.

I'm slowly working my way deeper into the technical side of activity pub. But I'm sure there's already plenty of you, who already made a deep dive.

What's a discovery you found most interesting or maybe even unexpected?

disclaimer: gringos please be kind to brazilians arriving to the fediverse, we're having a huge exodus due to political interference from the united states (through meta/google/x), if you're mean to them i am gonna curse your entire bloodline or give you rabies through wafrn bitting system.

When I started with #ActivityPub for #WordPress, it was a small experiment. Now almost 4 out of 10 #Fediverse servers are WordPress sites, and it is still growing, slowly but steadily. Come and join us @activitypub.blog 🎉

https://fedidb.com/software?st=servers

Alt...

Screenshot of fedidb, that shows some stats of WordPress in the Fediverse.

Concerning #HolosSocial, I still believe it's an interesting project because it brought something new to the #Fediverse.

Not only because you run your #ActivityPub server on your device, but mainly because you can own your identity with your own domain name.

My mistake was making it easy to run the server on your device, but not to get your own identity.
That will be my challenge in the coming months.

PS: I have no funding for this project and I work alone, so yes, it takes time :)

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.
