For those who worry about stability and work load for the Beaglebone (Black), here is one that has been up for 12 days doing actual, if not very sexy, work: monitoring and graphing. It runs http://armhf.com Ubuntu 13.04 minimal. The CPU is bored, most load seems to be because of IO. Graphs shown are from http://munin-monitoring.org/ as running on the BBB. Software running includes full LAMP stack and Postfix.
