Epiktistes is my home in the Fediverse. It is an instance of Ktistec, a single-user ActivityPub server like Mastodon, but with fewer users and fewer commits. Here's my introduction (last updated early-2025).
I wrote a series of posts about optimizing the performance of the Ktistec server, its build time, and its executable size: part 1, part 2, part 3, part 4, and part 5.
Some things I regularly write about, organized by hashtag:
I also wrote some #pointfreeverse.
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.

Thank you @jayvii for the build fix!
‘Twas a beautiful day for a ren faire…
I don't love the food, but I do enjoy the people… and the merchandise. There are a few makers who really pour heart and soul into making and selling something interesting and unique. And musicians who find an audience for niche songs about dragons, or being lost at sea. And where else are you going to encounter a hurdy gurdy?
And the weather—it was 75°F in December.
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!
Just cooked up a quick Mastodon theme for #ktistec :) https://src.jayvii.de/pub/ktistec-tweaks/file/css/mastodon.css.html
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.
Release v3.2.3 of Ktistec includes two big features:
The full changelog:
Added
Person, Group, etc.) overlay badges on actor panels.Fixed
Undo includes the undone activity.Like and Dislike does not.Changed
The next release will include support for Mastodon polls (FEP-9967).
Since all my websites and web-tools use the phenomenal #SimpleCSS framework, I thought it would also make sense to create a theme for #ktistec using those exact colours. Of course, this is also available from my ktistec-tweaks, next to the old purpleish-theme, which I had before.
Also new is the separation of the card-style post theming, which is also shown in the screenshot below, in its own CSS file.
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.
