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

A while back, I posted about creating a Forth-inspired programming language that uses emoji as words (functions) and said that I would post the source code. I keep my word—this weekend I cleaned up the code and published it.

I've built a tool that transpiles emoji source code into either Crystal or Python, and then builds and runs the transpiled source.

Here's the solution to Project Euler Problem 1, with comments so that you can more easily follow the flow:

💭 Project Euler Problem 1:
💭 Find the sum of all the multiples of 3 or 5 below 1000 => 233168

💭 Define a word to check if a number is divisible by 3 or 5
📖❓                    💭 Stack: ( n -- bool )
  📚                    💭 Duplicate n for two tests
  🔢3 🔀 🔢0 🟰          💭 (n%3==0)
  🔄
  🔢5 🔀 🔢0 🟰          💭 (n%5==0)
  ⚡                    💭 (n%3==0 OR n%5==0)
📕

💭 Declare variables
📦 💯                   💭 sum variable
📦 🧮                   💭 counter variable

💭 Initialize variables
🔢0 💾 💯               💭 sum = 0
🔢1 💾 🧮               💭 counter = 1

💭 Loop from 1 to 999 (inclusive)
🔁
  💭 Get counter and check if divisible by 3 or 5
  📤 🧮                 💭 counter
  📚 ❓                 💭 counter bool

  👍
    💭 If divisible, add counter to sum
    📤 💯 ➕ 💾 💯       💭 sum = sum + counter
  🔚

  💭 Increment counter
  📤 🧮 🔢1 ➕ 💾 🧮     💭 counter = counter + 1

  💭 Test exit condition: counter > 999
  📤 🧮 🔢999 ⬆️
🔚

💭 Print the result
📤 💯 😀

Forth is fun because it is so easy to create a simple implementation of the language. It's also very very terse, which makes the emoji-nature of a project like this shine through. Here's the program above with emoji digits, fewer alphanumerics, and less whitespace:

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!

#ktistec #crystallang #activitypub #fediverse

Joining my first D&D 2024 campaign tonight. Leaning toward playing a Sorcerer. I haven't paid even the slightest bit of attention to the evolution of the new rules, so I'm interested to see how it feels...

#dnd #dnd2024

would a "more from this actor" button be helpful on #ktistec? the use case is 1) navigate to an actor you're thinking of following, 2) click on "more from this actor" to fetch ~10 additional, recent posts. is there another feature that would be more useful?
