Rust should have stable tail calls - Trifecta Tech Foundation Tail calls in Rust have been talked about for a long time, but especially from the outside it looks like very little progress has been made. Let's change that!

Folkert and Waffle have submitted a project goal to move explicit tail calls forward in 2026. In this blog, Folkert explains the work ahead: trifectatech.org/blog/tail-ca...

The Network Time Protocol is generally used completely unprotected, much like the web was before HTTPS. At FOSDEM 2026, Ruben explained how we aim to push adoption of secure time (NTS) using pools of NTS servers.
