i'm "pretty sure" i have litestream backing up my epiktistes sqlite database, but getting it running was surprisingly fiddly...

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!

After thrashing through several attempts to add a smooth transition to the poll partial after the user votes, I realized that the best solution was hiding in plain sight. Turbo already sets the busy attribute on a turbo-frame element while the request is in progress, and adds a complete attribute when the request is complete. The only thing required was the styling!

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).

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:
