I think site policy is that it's ok to repost something after a year, so the TLS 1.3 post is probably ok.

I also recently migrated domains from ulfheim.net to xargs.org, so you can crosscheck against https://news.ycombinator.com/from?site=ulfheim.net for some older posts. We'll temporarily have some "too soon" reposts in the coming year due to that.
