#snacAnnounces

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.

#Fedify 1.6 is approaching with three major enhancements: RFC 9421 HTTP Message Signatures support with double-knocking for seamless backward compatibility, a new builder pattern for better code organization in large applications, and native #Cloudflare #Workers support for serverless deployments. These additions strengthen Fedify's standards compliance while expanding deployment flexibility across different environments. Stay tuned for the official release! 🚀

Improved authorization flows following RFC 9700 best practices

New features

Extended character limit (4K → 10K)
Code syntax highlighting
Customizable profile themes
EXIF metadata stripping for privacy

Important notes for update

Special thanks to @thisismissem for the extensive OAuth improvements that help keep the #fediverse secure and compatible! 🙏

Full changelog and upgrade guide coming with the release.

#ActivityPub

Introducing #BotKit: A #TypeScript framework for creating truly standalone #ActivityPub bots!

Unlike traditional Mastodon bots, BotKit lets you build fully independent #fediverse bots that aren't constrained by platform limits. Create your entire bot in a single TypeScript file using our simple, expressive API.

Currently #Deno-only, with Node.js & Bun support planned. Built on the robust @fedify foundation.

I am trying to figure out where I go to find open issues and discussions about the features for "quote posts" in the ActivityPub spec. Do they have... a git repo where they discuss it? (Is they in this case W3C?)

Is there a doc somewhere? I can't seem to find where they track these discussions publicly, but mastodon said the feature was already proposed upstream in ActivityPub, but that it was still in the works in discussions.

I want to read the discussions to figure out where in the process of implementing the feature we are. Are we still just discussing it? Is there a proposal request somewhere?

#ActivityPub

Does anyone know which #fediverse platforms return HTTP status codes according to https://www.w3.org/wiki/ActivityPub/Primer/HTTP_status_codes_for_delivery ?

Is there a table / list documenting the differences, anywhere?

#ActivityPub

There we go. #Snac2 up and running with the preferred installation process. Added custom styling to boot. One confusion point with styling is that it does NOT affect the root page (greeting.html) only the profile pages. So I thought I had done something wrong, but finally figured it out.

Forward-thinking journalists are not letting the “media apocalypse” happen to them. Instead, they’re doing the work that arguably has been most critical all along: building direct connections with their readers. @404mediaco's @jasonkoebler and @ProPublica's @ben join fediverse futurist @mike for a conversation about the discovery and sustainability of quality journalism.

I’ve complained there needs to be an easier way to move my posts to another ActivityPub platform.

But I’ll shush now after reading about Bluesky’s data export process. Good gracious.

#ActivityPub #ATProto

I've seen more people advocating for wider RSS adoption lately.

I was a heavy RSS user back in the day, but honestly, it’s a standard that struggles to keep up with modern demands.

In this short read, I break down why RSS’s pull model is inefficient and why push-based alternatives like ActivityPub are the future.

I'm glad to announce the release of version 2.61 of #snac, the simple, minimalistic #ActivityPub instance server written in C. It includes the following changes:

Migration from a Mastodon account to a snac one has been implemented. Please see snac(8) (the administrator manual) for more information.

Mastodon API: fixed timelines/public (it was showing less posts that it should).

Fixed over-zealous caching to the public timeline.

Some HTML tweaks and fixes to the web interface.

This release has been inspired by the painting The Hands Resist Him by #BillStoneham.

#ActivityPub trick question. If a C2S client actor identified by “http://bar.example/actor” posts {“id”: “https://foo.example/something”} to its *outbox* server endpoint, is that valid? Why or why not? If the answer is “it depends”, it depends on what?

From the latest Wordpress ActivityPub release, a few interesting tidbits.

First, quite intriguing to see tooling to monitor the progress of a self destruct request. Current platforms you just have to cross your fingers it works.

Second, you can provide a link to a Starter Kit to pull in all the accounts to be followed, again with a new UI to manage them.

Starter Kits? A standard format compatible with AP? Inquiring minds want to know.

#activitypub #fep

My argument for #ActivityPub over #ATProtocol is simple: if ATProtocol rules supreme, what will compete against #Bluesky’s firehose?

How many nodes are there on AT Protocol?

How many unique services that don’t resemble Twitter run on AT Protocol?

But above all, what happens if Bluesky gets bought by Musk or Zuckerberg?

With the Fediverse, we got established decentralization. Not theoretical—something that exists in the far off future—but decentralization that is here and now.

Happy 7th anniversary of becoming an official W3C standard, ActivityPub!

https://www.w3.org/news/2018/activitypub-is-now-a-w3c-recommendation/

We're creating something truly special here with the fediverse, and I am so thankful for everyone who contributes to it, whether with your time, money, or just by sharing your thoughts, your creations, your silly little jokes. Keep it up!

#fediverse #activitypub #standards #OpenWeb #anniversary

After a long silence, Tumblr confirms it is still planning to join the fediverse.

> The migration is still a work in progress, as we’ve previously detailed here, but we can say for sure that it will include support for WordPress’s existing ActivityPub plugins. We hope this comes as good news.

#Fediverse #ActivityPub #Tumblr

Just published a guide on setting up Snac on an Ubuntu VM using NGINX Proxy Manager. Snac is an incredibly lightweight #ActivityPub server. A true nom nom among fediverse platforms.
