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.
#crystallang developers… what can you count on being safe to access during a call to #finalize?
i have some class-level state that i’d like to modify via a class variable but even reading values via that variable seems to cause problems that eventually lead to crashes later in the program. (typically index out of bounds during some later garbage collection run.)

i've been working and wearing my nreal/xreal air glasses on this flight.
it's a trip when the plane is banking and turning. i also have a virtual ultrawide screen. i'm sure the guy next to me wonders what i'm studying over there...
many, many languages show up in my fediverse timeline. firefox translate selection (browser.translations.select.enable) appears to be what i need, but its language support seems limited.
