Are you participating in this discussion by sending email to
beagl...@googlegroups.com, or via some other way? I see it as an
email stream of a dozen or so messages a day. I'd call it pretty
active.

Do you require constant running, or do you sleep and run? If the
latter, you probably should respawn a fresh interpreter each time, do
the work and quit---otherwise you are at the mercy of memory leaks
that are hard to avoid in an interpreter.

No, IRC is the Internet Relay Chat software, a distributed chat
application that developers tend to use. When people log in into IRC,
they tend to watch it in real time, so potentially It provides more
immediate communication. This list is email-based so everyone has to
actively go and check the new emails.

If you place an analog voltage greater than 1.8 Volts on the analog
input pin of the BBB, you will destroy that input. This is different
from DS18B20, which has a digital one-wire interface using I think
standard 3.3V digital signaling. Note that 5V is too much: you need to
drop the voltage to 3.3V even for digital signals.
