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.
We released Crystal 1.19.2 to fix the request smuggling vulnerability (already fixed in 1.20.0) and a regression in Range#sample that could eventually lose randomness.
I’m working on handling OAuth token expiry as part of #ktistec Mastodon API support. Is my understanding that Mastodon issues OAuth tokens with no expiration correct?!?
does anyone use GNU Cash? any free (software) alternatives anyone recommends?
This release is a maintenance update: a few bug fixes, a security mitigation worth paying attention to, and some performance improvements for users on slow connections.
It's worth updating to pick up the SSRF (Server-Side Request Forgery) mitigation.
Fixed
Changed
A new Crystal release is out for version 1.20.0
Highlights: `@[TargetFeature]` annotation, new process spawn API, support for kernel TLS and io_uring. The latter requires execution contexts which is now in the final preview.

Do I want nazis in my fediverse feed? No!
Do you know how I do that—I block them and/or their server.
Do I want to read someone's opinion on random topic xyz? No, usually not. How do I ensure that? I turn off sharing and don't follow people who post excessively about topics I'm not interested in.
What I don't do is jump into their conversation to bully and harass them about their opinions. (Even nazis? Yes, fuck them but I'm not going to waste my time.)

It is unfortunately very easy to convince yourself that abuse and harrassment are OK as long as they're in service of a morally just cause.
I enabled lockdown on my iphone and other than an annoying label that says I have lockdown enabled there haven't been any obvious downsides. I think Apple’s warnings are overblown.
