Maybe. Was En57 endorsed from the very same stage by @jan.dudulski.pl as well? Quite a feat for a one star github repo with a name that is a joke 😂 https://github.com/mostlyobvious/en5714 May 2026 21:02 +0000at://did:plc:y62ur6ngx3kuyskutsrjhu2u/app.bsky.feed.post/3mltpoeclrk2ehttps://blacksky.community/profile/mostlyobvio.us/post/3mllzbvw3dk2jDynamic Consistency Boundary, a flexible approach for consistency in event-sourced systems.

And to remind myself how to write. On making encryption work with underlying JSON storage in Ruby/RailsEventStore. As soon as I've finished I've already had an idea for an alternative, drawing inspiration from Literal. I'm glad this one got out of the door! https://mostlyobvio.us/2026/04/encrypted-events-with-json-in-rails-event-store/02 Apr 2026 10:07 +0000at://did:plc:y62ur6ngx3kuyskutsrjhu2u/app.bsky.feed.post/3miixiymf4c2khttps://blacksky.community/profile/mostlyobvio.us/post/3me2r4buoes2xWe design everything on web mobile-first… except code samples. Here’s a look at three approaches: clever, boring and something in between.
