Long range thoughts

Lots of handwaving here. I'd like the server to run multi-threaded. At a talk at Stanford yesterday, the speaker liked Rust. He called it Safe C, good for embedded systems. A simple NTP server (no client, no ntpq server) is simple enough for an embedded environment. (When I run out of other

[PATCH] D75285: Mark restrict pointer or reference to const as invariant

hfinkel requested changes to this revision. hfinkel added a comment. This revision now requires changes to proceed. Unfortunately, we cannot do this kind of thing just because it seems to make sense. The language semantics must be exactly satisfied by the IR-level semantics. I certainly agree
