Hey Ron/EBo, Do y'all have any libixp examples you could share? -j On Sat, Jul 30, 2011 at 6:12 PM, ron minnich rminn...@gmail.com wrote: I'm still a big fan of libixp. It's written in a way that I feel is a good fit if you're used to Plan 9 C style. I've made a number of uses of it. ron
Re: [9fans] Maybe a weird Plan 9 project.
There is server and client code in the repo. We've been using it for some time now at sandia and other places. Writing a synthetic to work for libixp is pretty easy. ron

Issuing RPCs from Emacs is really not that bad if you can stomach elisp. in other words, it's a hateful experience that will leave your soul as dark and twisted as an urskek's. ;-) - erik

[9fans] Maybe a weird Plan 9 project.
I was outside watering plants this morning that seem to be proof of my not-so-green thumb I have for gardening and was thinking of an interesting home-automation use for Plan 9. What I'd like to do is get the following: 1. Moisture sensor I can embed in some potted plant soil, and read from Plan 9. 2. Tubing. 3. Pump I can control from Plan 9 based on moisture feedback. 4. Perhaps a rain bucket water source. Anyone else using Plan 9 for automated gardening? I was thinking this could be the use for Plan 9 on my guruplug. Any ideas how best to achieve this? If some stuff isn't supported by Plan 9, I'm willing to investigate the writing of drivers to make it work properly. Just trying to find new ways to be lazy I suppose. Dave

Re: [9fans] Maybe a weird Plan 9 project.
I don't get the point of plan9 here. Learning C should be a matter of hours for such an unspoiled mind, so I'd say go with bare hardware.

From what I recall a CM11 is quite different from a CP290 but I can probably steal enough to make my task easier. My CP290 has been pretty reliable so far (25 years?) but I wonder how many are left -- does anyone else use it with plan9?
