Spent the day testing ZFS, via FreeNAS, as a VM storage medium. Got it to do snapshots, rollbacks, clones and the most important, incremental backup to remote systems.
The goal is for this to allow my core data to be replicated to remote repos for security issues. This is most imperative after Irmaria.

Automata theory is the study of abstract machines and automata, as well as the computational problems that can be solved using them. It is a theory in theoretical computer science and discrete mathematics (a subject of study in both mathematics and computer science). The word automata (the plural of automaton) comes from the Greek word αὐτόματα, which means “self-acting”.

While I see Bitcoin as a game changer for Fintech, the blockchain is the real revolution.
I use this script to get alerts from some systems to insure they are still up. It gives me local IP address, hostname and the WAN IP for the network.
#!/bin/sh
IP=”$(ip addr | grep ‘state UP’ -A2 | tail -n1 | awk ‘{print $2}’ | cut -f1 -d’/’)”
IP2=”$(curl ifconfig.co)”
HST=”$(hostname)”
CN=”$(curl ifconfig.co/country)”
CT=”$(curl ifconfig.co/city)”
HST=”$(hostname)”
echo $IP2 > /tmp/$HST
echo $IP >> /tmp/$HST
echo $CN >> /tmp/$HST
echo $CT >> /tmp/$HST
/usr/bin/sendemail -t info\@mydomain.org -f hb\@mydomain.org -u “HB from $HST” -s smtp.server -o message-file=/tmp/$HST;

The U.S. military’s experimental X-37B space plane landed on Sunday at NASA’s Kennedy Space Center in Florida, completing a classified mission that lasted nearly two years, the Air Force said.
The unmanned X-37B, which resembles a miniature space shuttle, touched down at 7:47 a.m. EDT (1147 GMT) on a runway formerly used for landings of the now-mothballed space shuttles, the Air Force said in an email.
Tired of losing the USB adapters !!
