You can't just change the domain part, as it's an integral part of all ActivityPub object identifiers. Your followers, for example, expect posts from you from the domain they initially followed, and will reject everything if it's changed. This is not a limitation, it's just the way ActivityPub is.

If you want to change the domain, you must move all your accounts from the old server to the new one, while both instances are operative.

      "After all, you don't need a thousand-node cloud to write something worth reading."

      This phrase appears in the "under the hood" section of my blog.
      Just now I was reading a post by an "influencer" on a well-known social media platform. The post was biased, lacking in content, useless. Digital waste. A waste of bits and energy. Shortly after, I read a fantastic post written by a user of a instance, and I know it's running on a Raspberry Pi, at their home.
      And that phrase immediately came to mind.

      Goodnight, world.

          Hi, author here. Some explanations:

          MUTE: silences an author forever. You'll never read anything from this poster anymore. Like block in Mastodon and other implementations, but without sending a Block activity.

          Hide: hides a post and everything hyerarchically below (i.e. the full tree). The conversation won't be shown to you forever, and any incoming post in any of the levels will be dropped. No other part is informed about it, it's just a local operation.

          Delete: deletes a post from your timeline. If it's part of a conversation, the branches below are left dangling, but are still shown in you timeline. Also, if you are the author of the post, a Delete activity is sent to everyone involved, so your post (hopefully) disappears everywhere.

            Yeah. I can't see the difference between mute and delete for a post not written by me. It's gone either way isn't it?

            The only difference is informing other parties about the delete if it was written by me, or am I overlooking something?

            Edit: I asking because I'm thinking maybe one of the buttons could go away to make room, or change its behavior. Like "hide" could be instead "mute" to only not inform anymore on the conversation, but don't delete it (like mastodon does)

              So a question:
              Does someone know the difference in "hide" and "delete" under a post?
              What does this technically do, and how does it affect what I or others see from this post?
              Is there a different behavior if it's my own post or something in my timeline?

              It seems both options delete the post from my view. I only don't know whats the difference beside that.

I can, and have, made such a link from my blog post to the posted snac comment, but snac doesn't have a reply link. I know on mastodon it will have one and then ask you to log in to your instance to post a reply. Any suggestions on how I can include one or do you or anybody have a work-around or other suggestions?

                      There is no "this is a DM" special mark in an ActivityPub Note object that I know of. If a post does not include the magic "for everyone" target address, an implementation should assume it's private and mark it as such. shows this kind of messages with a small lock emoji next to the poster's name in the same timeline as public messages.

Apart from Tusky (already mentioned by Stefano), there are other Android apps that work acceptably with snac, like Fedilab, AndStatus, Pachli (previous versions used to hammer the server, but it seems that the latest version no longer does) and tooot (though, if I recall correctly, it's no longer maintained).

                                        Alright I've got myself a 1GB RAM VPS for $12 for the year (a 4x increase over the Pi 😆). It's in London and everything for super low latency! I managed to get installed through some hackery and migrate my blog and instance to it.

                                        One slightly weird thing I had is that inbound traffic on both SSH and HTTPS was returning a "connection reset by peer" for a while. It seems to be working now, but if some IPv6 folks can check https://cablespaghetti.dev loads properly over v6 for them now, it would put my mind at rest.

It happens quite often when I post and sometimes when I don’t. I think this is due to having more content on disk than when I first set it up.

                                                It's fun to run servers on old, slow computers. Posts that showed up on my big fat server a couple hours ago are only showing up now, simply because it's too busy to receive all relevant notifications at once. Other instances seem to be backing off for a while, and try again at random intervals so the load on this box remains low. Pretty cool, assuming that's actually how it works!

                                                Only when a post is boosted or replied to do I run the risk of my hot-babe CPU monitor turning nsfw. So better keep it boring, I guess.

                                                  Added a server-wide Webmention hook; this way, if somebody out there (that supports Webmention) links to a user or post in this instance, a notification is sent (this is the complementary of what was implemented in version 2.76).

                                                  Fixed regression while sending email via pipe on OpenBSD.

                                                  Fixed Markdown parsing when the URL has parenthesis.

                                                  Always show the 'pending follow confirmations' section if there are any (even if the toggle is off).

                                                  If a metadata value is an account handler, it's also tried to be validated (rel="me" links).

                                                  Another search by URL tweak (this time for Pixelfed links).

                                                  Mastodon API: fixed a bug that made some boosts disappear after being shown in apps like Tusky, added followed hashtags maintenance, other minor changes.

                                                  Renamed command-line actions create_list to list_create and delete_list to list_remove.

                                                  The default favicon URL can be changed from the server configuration.

                                                  New command-line option export_posts, to export all posts by a user in a JSON format compatible with the one generated by Mastodon.

                                                  The command-line options to send notes also allow an optional -r argument, to set the URL of a Fediverse post this note is a reply to.

                                                      In snac on an ancient Raspberry Pi news, I switched from XFS to Btrfs and my memory pressure issues are now a thing of the past. As a bonus I can use snapshots for backups instead of taring up the many small files that snac generates (it has no traditional database).

                                                      I tried tuning various parameters but after some reading came to the conclusion that lots of small files with very little RAM is about the worst case scenario for XFS.

But with a hyper-optimized SSH handshake taking over a minute, I have no hopes for 2k RSA signatures or any kind of TLS handshakes with remote instances happening in anywhere near the timeframe they would need to..

                                                          I love independent proposals, so next release of will include support for Webmention. It's a protocol built on top of web standards and part of the IndieWeb. It helps web page maintainers and bloggers to know when one of their URLs are mentioned in other platforms by providing a webhook to receive notifications. In snac's case, all links written in a Fediverse post (directly or using the Markdown format) will be tested for Webmention endpoints and notified if they exist.

                                                          I don't know how many web sites out there implement Webmention (I guess very few), but given that it has been very simple to implement, here it is.

                                                          Long live the non-big-tech Internet.

                                                              I quickly restarted the service from the platform but then it got killed again and I didn’t notice until this evening. I have now rebooted the server, maybe that will help until I get home from my camping trip with my kids.

                                                              For those who don’t care about my latest ADHD obsession, don’t worry I’m sure I’ll move on to a different one soon, and here’s a steam train…

The combination of the load from sending out to many ActivityPub servers and all those servers trying to generate a thumbnail card thing by hitting the website was just too much for the little Pi. I'll have to see if I can do anything to optimise caching...
