HN discussionAnubis does this. Happy Eyeballs ( https://en.wikipedia.org/wiki/Happy_Eyeballs ), IPv6 privacy extensions ( https://oneuptime.com/blog/post/2026-01-15-ipv6-privacy-exte... ), and devices migrating between home and mobile IP addresses as the person moves have all caused issues with this. Fixing this is hard, but I have been trying.

HN discussionI was thinking I recalled something like that, but the nice thing about the TS ecosystem is that you can write the same language, importing and using the harness sdk types. Go has the plugin package, but I haven't actually seen anyone use it (outside of toys and blog posts) https://oneuptime.com/blog/post/2026-01-25-plugin-system-go-...

HN discussionPostgres 'at time zone' is confusing, but it's internally consistent. Once you understand what it's doing, you can work with it and it will reliably behave the way it's designed to. https://oneuptime.com/blog/post/2026-01-25-postgresql-timezo... -- TIMESTAMPTZ AT TIME ZONE 'X' -> returns TIMESTAMP in timezone X -- TIMESTAMP AT TIME ZONE 'X' -> returns TIMESTAMPTZ treating input as timezone X
