RIME has had sync_dir for a long time (since librime-1.5 era, ~2017). The mechanism is well-documented in rime/home/wiki/UserGuide and github.com/Mintimate/oh-my-rime‘s English guide. But the docs assume you’ve been a RIME user for a while — they skip some “first-time installer” gotchas. This article covers the three-device workflow on Linux / Mac / Windows in 2026,... » read more

Teredo was supposed to be the way to give every IPv4-only user behind a NAT box a globally routable IPv6 address. In 2026 it’s basically a museum piece — Microsoft ships it disabled by default, public Teredo servers have all but disappeared, and Linux support is gone.

That’s all you need for the engine itself. fcitx5-rime — the binding into the fcitx5 IM framework. Pulls librime... » read more
