2013-02-23 Thread mycroftiv 9gridchan
Hello 9fans! After a year away from public Plan 9 projects and development I have returned to full-time work on Plan 9 software and services. Before posting about my current software project, I would like to make note of two pages I added to the Bell Labs plan 9 wiki which are intended as an overvi

So I read in New Scientist one time that being awake for more than a certain amount of hours is the same as being lightly drunk. I shouldn't be on the Internet at all really right now.

Sorry. What I meant was that rc's already-open file descriptors for the pipefile'd file aren't affected by the bind, so for an rc to be affected you need to run a new one. I saw this as being analogous to how it sees environment variables. I'm not interested in environment variables anyway, it'

cpu and exportfs accept a pattern file (-P) option. with this, you can make cpu export only the namespace parts that you want to give the cpu server access to. the difficulty lies in how to decide what you want to export and still keep cpu usefull. if you really assume a compromized cpu server, t

I know that about /tmp. I know devenv too. By the way, have you ever noticed that the *env libc functions only allow accesses to env files with names of length 100 - strlen("/env/") - sizeof '\0', while rc allows names of up to 256 characters? I'm not too concerned about that one, just saying it
