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.
After I release a new version of ktistec, I build the server commit-by-commit to see which commits increase the server executable size and build time the most. I do this because I’ve learned that small implementation details (inlined code, small methods, using blocks) can have large impacts on these numbers.
Here's the output:

Overall, the server executable size increased by about 1.1% and the build time increased by about 6.8%. Maybe that's not too bad for a major feature, but let's dig in.
It's nice to see that three commits account for almost all of the increase in server executable size:
But, compare 5724a58d to 8ae2cbd4 (Add `language` to `Account`). It added +22 loc but didn't increase the server executable size as much.
In any case, I'll look at e2327eea first. I'd like to understand why this relatively small change adds 130,240 bytes to the server executable size!
Ktistec release v2.4.3 supports language translation.
Inspiration for this feature comes from Mastodon.
In order to enable translation, you need an API key for either DeepL or LibreTranslate. These are the only services Ktistec supports at this time.
Posts from properly configured accounts on supported servers, like Mastodon, include the content language. On posts like these, Ktistec will display a button to translate the content if the language differs from your language.
Unfortunately, not all Fediverse/ActivityPub servers explicitly support language (I mean, Ktistec didn't until just now). And not all users correctly set their posts' language, so ymmv... but it has been hugely useful for me.
I'm going to focus on site customization next (colors, etc.).
@jayvii i just tagged a new release. it looks like the docker build built the release successfully. congratulations and thanks!
i was initially excited to see a new album i'd overlooked by the world/inferno friendship society. their website had been silent. then i learned that jack terricloth/peter james ventantonio died in 2021 and this was a postmortem compilation, which was very sad news.
when you add new functionality to old code, do you also identify and accumulate a hundred little fixme's to nearby code... or is it just me...?
do you save the changes up for a final cleanup pass or make the changes then and there? do you put each fix into its own commit?
🤔
i'm running a ~6 hour pair programming, test-driven development session for our dev team. i feel like too few organizations ever pause forward production and invest in training/practice.
Seattle 2025 Worldcon is having a sale on memberships Black Friday through Cyber Monday (November 29–December 2)!
Watch this space for the discount code, or come talk with us in person this weekend at GeekCraft Expo Seattle or find information at our fan table at Loscon 50.

when i’m back in new york, i love to browse the aisles at the strand. i picked up a used copy of revelation space by alastair reynolds for book club.

Release v2.4.2 fixes a few more bugs. Only one is a regression—I found the others while testing. In this release:
Fixed
del, ins, and s elements in sanitized HTML.redirect_after_auth_path on browser navigation.FileUtils.mv to move uploaded files. (fixes #117)Thanks to @jayvii for help with troubleshooting the last one!
