#ActivityPub developers: which of these HTTP caching headers does your software publish or consume?

Progress report on my #activitypub server I'm writing because I'm bored at my in-laws':

I'm back home again. Haven't given up, just postponed it a bit.

Idea for experiment: mail to fediverse?

@selfhosted

My ambition: having people writing to "username @ domain dot ext" and mail content goes into public, or private, on fediverse "handle @ domain . ext".

Someone already did it? Pros and cons? Disadvantages are more than benefits?

I heard about a trick called "mail2mastodon" but before doing deeper research I first wanted to understand how the effort is, and if it's worth.

#activitypub #fediverse #howto #mail #selfhosting

The reason Mastodon-flavor ActivityPub has been stagnant for most of the last decade is the only people who take the lingering cultural and structural issues seriously are working on what comes _next_

It really ought to concern anyone who still believes in this place that AP doesn't have its own event to match AtmosphereConf. There was exactly one over half a decade ago. All the energy at the 2026 event was exponential starting from the 2025 event. The PLC directory is headed to the independent org announced there. The IETF has the protocol. It's happening, right now.

If you're looking at Bluesky, you're looking at where the puck is, not where it's going.

You want more people to use AP? Stop complaining about people building on and using AT and start trying to understand why they are. I've been saying this for years now and nothing's changed on this side.

How to Install #Pleroma on #Ubuntu #VPS (5 Minute Quick-Start Guide)

This article provides a guide demonstrating how to install Pleroma on Ubuntu VPS.
What is Pleroma?
Pleroma is a free, open-source, self-hostable microblogging server that speaks the #ActivityPub federation protocol—so your users can interact with people on other #Fediverse platforms (e.g., Mastodon) while you keep full control over your server ...

#ActivityPub な #Fediverse でも、よりグローバルにハッシュタグをフォローできるサービスが爆誕していた。
能動的に興味のある話題を探しに行く時に重宝しそう

Tweaked my #wordpress #activitypub config to use only the Blog as the Actor, instead of both Blog and Author. Now, the Blog actor federates posts directly, rather than boosting posts from each Author.

Has anyone else tried this? Did it cause any issues with boosted Author posts that were previously federated?

Would I need to “repost” all previously federated content for it to appear under the Blog Actor?

Reminder that the fediverse is a "group project" and really does take a village.

Does anyone have a good #ActivityPub integration for #Hugo? I'd like a link to posts to be published and then show comments on the blog. I've seen a few people get it to work.

Yesterday I shared Discover more of the Fediverse with tags.pub in my Pook-Emu Bee links for the day. The post introduces a new feature for the ActivityPub for WordPress plugin: Subscribing a site to the tags.pub relay for hashtag boosting. It provides the following instructions for self-hosted WordPress sites such as this one:

For self-hosted WordPress sites, head to Settings → ActivityPub → Settings and scroll to the Relay section. Add one of these URLs:

• Inbox: https://tags.pub/user/_____relay_____/inbox
• Shared Inbox: https://tags.pub/shared/inbox

The instructions offer two URLs and say “[a]dd one.” I added the second because it is more aesthetic. But I did wonder what the difference was between the two URLs. So too did commenter bocops:

Could you explain the difference between the “Inbox” and the “Shared Inbox” relay URLs?

Post author and ActivityPub for WordPress developer Matthias Pfefferle answered the question:

from a user perspective there is none. you can use either one of them!

While the instructions do say “[a]dd one of these URLs” and I interpreted the instructions correctly in the first instance, I will offer my two-cent take that it does raise a question why there are two URLs and how they may differ. I dealt (and will deal again) with this issue regarding site feeds. On NLJ, I make a point of promoting various feed formats, namely RSS, ATOM, RDF, and JSON. However, I am sensitive to the fact that many readers may not be familiar with feeds, much less different formats. Thus, I explain that RSS (our default) and ATOM should work in all feed readers, so most people should use one of those formats (usually RSS since that is the WordPress default at /feed/) unless they have a specific reason to use JSON (which I use to subscribe to NLJ in Miniflux) or RDF (that seems less likely but maybe there are some RDF fans out there). Regarding the tags.pub  post, I would recommend offering one link as a sort of “default” while adding a note (or footnote) on the distinction (if any) for people who may be interested.

All that aside, tags.pub works for me and is a very nice feature for WordPress sites (both .com and .org) taking advantage of new Fediverse features. I tip my hat to Mr. Pfefferle and everyone who is working on it.

Do you have a basic shared hosting plan? You can now host a #Fediverse instance on that plan. Check out #Starling: https://github.com/dfaria-eu/Starling

Socialhome v0.23.0 released

Work continues towards a full replacement of the UI layer! @{alain@jase.social} has been hard at work again, working on both the UI layer, but also the backend and the federation library. Massive kudos

This is the last release where it will be possible to use the old UI. The next release is expected to completely remove the old UI, which will be a much welcome clean-up of the code base.

When updating, please note the instructions for running Socialhome with the new UI. The old setting to enable the new UI is gone, instead you will need to route to it using your reverse proxy. In the next release this will become mandatory as the old UI will disappear from the Socialhome backend container.

While things are in flux, unfortunately there aren't very good example ways to run the Socialhome backend and the new frontend. We're hoping to improve on this with the next release, when the old UI will be fully removed. Please pop in our chat room if you have issues attempting to run Socialhome.

Please note due to build issues with the old UI, arm images are not available for this release. If you need them, please ask in the chat room and we will figure something out.

This is not all! The release of v0.23.0 also contains a bunch of other changes and fixes. See the full changelog. Additionally, the federation library has received a ton of changes and fixes which can be found here.

Installing and updating

We recommend using the Docker images.

Notes on how to use the Docker images can be found in the docs.

What is Socialhome?

Socialhome is best described as a federated personal profile with social networking functionality. Users can create rich content using Markdown. All content can be pinned to the user profile and all content will federate to contacts in the federated social web. Federation happens using the ActivityPub and Diaspora protocols.

Please check the official site for more information about features. Naturally, the official site is a Socialhome profile itself.

• Official site
• Documentation (for admins)
• Code repository (GitHub mirror)
• Chat room on Matrix

Try Socialhome?

If you want to try Socialhome first before trying to install it, register at https://socialhome.network and then ping us with a comment on the user name chosen to get the account approved. You can also request account approval in the chat room. This unfortunately approval step is due to spammers.

After realizing how many ultra-light and simple options there are to run small #ActivityPub servers on tiny servers, #ATProto seems even more insanely complex and unsuitable for an actually decentralized social web. While it's cool to see the momentum behind EuroSky, I can't help but wonder... why? It's all here. Just come on in and join us in the Fediverse.

Am I correct that with #ActivityPub, any org can run a server with their name in the domain with each member getting their own username, but using #ATproto, every individual would need to get their own domain name? Are subdomains possible? And those would probably just redirect, the structure and costs meaning they probably don't actually represent an app view or PDS or whatever?

Journey with self hosting for personal blog and fediverse

@selfhosted

Hello, I followed the "selfhosted" instance on LemmyWorld in order to be able to talk about my experiences having them in order, without confusing criteria into Fediverse. Hoping they can be useful to others.

Current setup: Hostinger vps kvm2 plan, Debian12, YunoHost, Hostinger's docker manager installed.

Personal background: blind since birth, (I don't see), I'm mostly a computer power-user, worked and studied with ms-dos since 1989 until late 90s. Basic GNU/Linux knowledge in 2002, then interrupted in 2004.

I don't care talking about disability when discussing unrelated topics but it's necessary in this case as my needs are quite different from others.

So, I've been scared by self-hosting and have had shared hosting web sites until now. Until @_elena started self hosting her digital echosystem from scratch using YunoHost.

Due to lack of drivers I stopped with Linux on my private machine, drivers for the Braille display I had, and then the uneffective (at least for my need) screen reader capabilities on Linux's GUI based distros.

Finally in January 2026 I jumped in the dark after reading Elena Rossini's blog about YunoHost and having explored their demo pages. At the worst, I'll cancel the contract...

In the end I've managed to run WriteFreely, WordPress, CastoPod and GoToSocial, just by YunoHost; but if someone says terminal knowledge is not needed, this is a complete lie.

Where a system (such as YunoHost) can do the dirty work configuring postfix and nginx, I'll support it but it has its disadvantages: not every app can be installed through it.

For me it's very difficult to create and look after a config file on my own, it's frustrating for a sighted to miss a punctuation sign, an apostrophe, an indent. Let alone for me! A single space skipped, can crash a system.

A lie even saying that AI completely helps. It does solve some small, simple, immediate tasks but it has some mistakes as well. The so-called allucinations which create a real mess if you can rely on no personal skill.

Such as "sudo yunohost tools cert-install", or similar. AI wrote "cert-install" while the real command is "cert install"! A power user can get rid of it and correct, a beginner with no command-line knowledge, just copies, pastes, and gets scared.

My late attempt has been Madblog, a static markdown-based blogging platform with Fediverse activitypub in it, so I learned what Docker is and how it basically works. But I gave up, due to several timeouts and activitypub slow-downs. I think I'm going to use WordPress for blogging then. In case of comments it'll be more intuitive for non-fediverse folks.

Hopefully share others' experiences as well!

#ActivityPub #blind #fediverse #introduction #selfhost #selfhosting #WordPress #YunoHost

I've been saying for a while that we need something like FediCon in East Asia. A dedicated conference is still a stretch, but I've been thinking about a smaller step:

@COSCUP@floss.social 2026 (Taipei, Aug 8–9) is accepting proposals for community tracks. It might be worth trying to open a Social Web track there—something in the spirit of the Social Web devroom at FOSDEM.

Nothing is decided yet, but if you're working on #ActivityPub, the #fediverse, or anything in the social web space and might be interested in speaking (or co-organizing), I'd love to hear from you.
