Epiktistes

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.

Release v3.9.0 of Ktistec

I shipped back-end support for algorithmic feeds in the last release. In this release I shipped front-end support. The feature needs testing and polish, so it's still not possible to navigate to the feeds editor, but if you know where to look, you can try it 😉.

"Algorithmic feeds" currently means support for custom hashtag, mention, and keyword feeds (e.g everything that mentions "#fediverse" and "#activitypub" but not "x" or "facebook").

Here's the full changelog:

Added

Front-end support for user-defined algorithmic feeds.
Allow editing optional properties on published posts.
Support undoing a dislike.

Fixed

Handle concurrent duplicate inbox delivery.
Don't apply custom themes on the drafts and posts pages.
Adapt duration units in thread analysis.
Restore the spinning loader.

Changed

Restrict theme overrides to color and reduce reliance on !important.
Render the homepage description in a basic segment.

Removed

The deliver_to state and the recipients fallback.

In the next release, algorithmic feeds get wired into the navigation!

i was overdue for my annual (or maybe decennial) .emacs checkup and service.

i removed support for haskell and ocaml programming—i love haskell but i'm not writing it anymore. rip. i deleted packages that support tools i've replaced with other tools (e.g. ack → rg) or i just don't use (origami, counsel/ivy/swiper, etc.).

it looks like i need to migrate from a few packages to newer packages (smex → amx, restclient → verb, etc.). smex hasn't been maintained since ~2015 so maybe it is decennial...
