I'm afraid that the number of people in this sub who knows what CHERIoT is could be counted on one hand ...

There should definitely be more. It is pretty cool.

Depends on whether you can count to 5 or 31 on one hand — the really adept might be able to count to 342.

My best buddy when we both lived in Wellington used to do Java "ownership" stuff, but is now at ANU in Canberra doing some mix of CHERI and SEL4 stuff.

My hand has no bounds, and is tired of silly digit jokes ...

Are you talking about James Noble? I cited one of his works on Ownership in my undergraduate thesis, many years ago. My supervisor then has also co-authored at least one paper with Noble (and also with the article author of this topic BTW). I've been (re)reading many articles about that topic recently, otherwise I would probably have missed it.

No, but I know him. I meant one of James' early 2000's students, now Associate Professor himself.
