I was updating with my personal breadcrumbs when you replied. Richard was a colleague of mine - the plan9 scene leads very quickly to luminaries - I have had the privilege of meeting some very talented programmers who are humble so one day you will be on a webpage and go "gosh, I know that guy"

I'd love to chat more if you'd be willing to drop me a line. My email address is in my profile. Too bad I'm too late for the plan9 scene. I'm fascinated to find this long-running nexus between OS hacking and teaching programming, because that's kinda what I've been up to lately and I've worried some that it bespeaks a lack of focus.

I sent you an email

Thanks! Hope you received my response.

It feels nice to be, at least in part, responsible for this exchange. :-)
