I wonder if you could use/abuse Mastodon polls (FEP-9967) to distribute posts that provide near-real-time status updates (I'm thinking about severe weather alerts but I'm sure there are other use cases)?

Create a poll with an expiry far in the future and a token set of options (ideally just one—"Do you opt in?"—but poll implementations seem to require at least two).

Nothing seems to prevent the content of a poll from changing—and this is the key insight. The FEP says, "The type of a poll (single choice / multiple choices) and its options might be changed at any time. In that case the author of the poll MUST reset the vote counts." So broadcast updates via the content.

It would be a lightweight way to follow a single item without following the actor, built on top of implementations that already exist.

I have Markdown editing working in Ktistec!

Which post was written in Markdown?

Voilà!

This is an often requested feature. It also makes Ktistec usable in browsers when JavaScript is disabled. The Markdown editor supports autocomplete and autosave, just like the rich text editor. Expect this to show up in the next release.

The big feature in release v3.2.4 of Ktistec is support for viewing and voting on Mastodon polls (AKA FEP-9967: Polls). This feature took a surprising amount of work. Some of the effort was due to my struggles with visual design, but getting the behavior right was also tricky. For example, a "vote" is just an ActivityPub Note, but unlike other notes, it shouldn't appear in a poll's replies (it could, but that would be redundant and confusing). So I had to add exceptions throughout the code to deal with this. A custom Vote object type would have been nice in the original implementation.

Added

• Support for viewing and voting on polls. (fixes #49)
• Added tooltip to notifications menu item summarizing new notifications.

Fixed

• Improved wrapping of actor panel follow/refresh information. (fixes #130)
• Autocomplete now works correctly when adjacent to a Trix attachment.
• Image title attributes are now preserved.

Changed

• Moved avatars to the bottom of the object detail view.

Thank you @jayvii for the build fix!

Polls are rendering!

I'm working to get all of the little visual elements available across the Fediverse to render in a usable way on Ktistec. When released, users will also be able to vote on polls.

#ktistec #activitypub #fediverse

Release v3.2.3 of Ktistec includes two big features:

• FEP-1b12 Group federation
  Improved federation with Lemmy and other forum-type servers. Ktistec supports community and thread follow/unfollow, as well as up-vote/like (down-vote/dislike is supported but there is no visual affordance for that yet).
• FEP-9098 Custom emojis
  Support for viewing custom emoji in posts and on actor profiles. Ktistec does not yet support custom emoji creation and management.

The full changelog:

Added

• Support for viewing custom emoji in posts and on actor profiles.
• Actor type (Person, Group, etc.) overlay badges on actor panels.
• Colored fallback avatars for actors without icons.
• Support for robots.txt.

Fixed

• Federation with Lemmy and other servers that support FEP-1b12.
  • Shared inbox support for local actors.
  • Serialization of Undo includes the undone activity.
  • Serialization of Like and Dislike does not.
• Notify only once for an object's first received activity.

Changed

• Accumulate metrics by hour for finer granularity.
• Clean up presentation of public followers/following pages.

The next release will include support for Mastodon polls (FEP-9967).

#ktistec #crystallang #activitypub #fediverse

I've improved federation support for Lemmy and other servers that support FEP-1b12 Group Federation.

I had to increase the number of available file descriptors on my personal server 4x because of the resultant inbound volume of ActivityPub activities! I liked a federated post and DOSed my server.

#ktistec #activitypub #fediverse

The big feature in release v3.2.2 of Ktistec is pinned posts with support for the Mastodon Featured Posts collection. Federation works both ways—pin a post on Ktistec and it will show up as a pinned post on Mastodon and vice versa. When you refresh an actor profile, Ktistec also fetches and updates the actor's pinned posts. This is another small step in the direction of supporting all features that Mastodon-compatible client applications expect to access via the API. It's also useful in its own right.

The other major feature, which I posted a short video demonstrating here, is X-Ray Mode. X-Ray Mode is a developer and power-user tool for inspecting ActivityPub JSON-LD representations of actors, objects, and other content. Pressing Ctrl+Shift+X on any page displays the data behind the page—like an x-ray. You can:

• Cached Version: View the local JSON-LD representation stored in the Ktistec database
• Remote Version: Fetch and view the original JSON-LD representation from the source server
• Navigation: Click on any ActivityPub IRI to navigate to that object
• History: Use Alt+Left and Alt+Right to navigate through your viewing history

This feature is useful for debugging federation issues, understanding ActivityPub structures, and verifying how content is stored and represented.

Here's the full changelog for the release:

Added

• Support for pinned posts and the Mastodon "featured posts" collection.
• X-Ray Mode for viewing and navigating JSON-LD resource (actor, object, etc.) representations.
• Back links on thread pages for easier navigation. (fixes #1)
• License page for LibreJS compliance. (fixes #127)
• Highlighting of recently fetched hashtagged posts.

Changed

• Improved presentation of audio and video media.
• Refactored theming/styling implementation.

The next release will focus on smaller features and bug fixes.

Enjoy!

I've streamlined theme development in Ktistec. The theming system uses a hierarchy of CSS custom properties and fallbacks. Theme authors can customize a theme at multiple levels:

Base Colors Only

Define only base colors like --text-primary, --bg-primary, --bg-input, --semantic-primary, etc. Derived colors will auto-generate using color-mix formulas. For example:

:root { --semantic-primary: #ffa500; }

From this one line, theme-appropriate colors like --bg-accent-code, --anchor-color, etc. auto-generate.

Base Colors Plus Derived Colors

Define base colors and derived colors. Derived colors use custom values when defined. Undefined derived colors auto-generate. For example:

:root {
    --text-primary: #333;
    --text-primary-2: #ff0000;  /* red for this specific shade */
}

Given this theme, derived shades like --text-primary-1, --text-primary-3, and --text-primary-4 auto-generate. --text-primary-2 is red.

The simplest possible interesting theme redefines the primary semantic color. The single line above (in Base Colors Only) would result in the following, with button color, link color, disabled, selected, and hover states all derived automatically:

These changes will be in the upcoming release. Existing themes will continue to work, as is.

Experimenting with x-ray mode for ktistec.

Release v3.2.1 of Ktistec adds support for bookmarking posts. This was so immediately useful I don't know why it took me so long to get around to it!

Pinned/featured posts are in the works for the next release.

The full changelog:

Added

• Support for bookmarking posts.

Fixed

• Invalidate user's sessions after changing password.
• Ignore supplied languages that don't conform to expected format.

Changed

• Upgrade Kemal.

In other thoughts... I'd like to make followed hashtags more consumable. I follow ~10 hashtags and: 1) it's hard to tell what's new, 2) it feels like they arrive in large batches that are difficult to digest, and 3) the reading experience is meh.
