OK, best way (and this really is an IoT question if you look at it) is to look at the most efficient (ie. fastest, least labor intensive) way of doing it. BBB's are small, so please don't try to install an SMTP server and stuff on it when you can do this. The mutt and the HTTP API approach are

OK, I just got my BBB so I gotta talk a bit out of my butt (having not done this yet myself). What you need to do is get it "interrupt driven". However you do it. I'm thinking there is a GPIO pin that has this capability (and realistically accessible via the OS in whatever dev environment you

I had a problem with my core drivers for the host not installing (so you can teather the BBB to a desktop via USB to miniUSB on the BBB). It just came up with red X's every time. There are a lot of "fixes" out there that are pretty flakey so I thought I'd post the most linear path I found.

Ok, experimented with it some more and came up with a basic protocol for getting it to boot. What you do is you kind of fiddle with the power button and keep plugging and unplugging the USB cable (I'm powering my BBB through the miniusb to my Windows 10 desktop). What you do is you ground

There is kind of an involved way in C that is how it is done (similar to how Apache runs as a long-running daemon). What you do is you fork() with the parameters set up such that it invokes a daughter shell process that survives after the parent process is terminated. The reason why the
