Why do electronics die ?

A great video on electronic devices and their frailness.

Heart Beat shell script

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;

Test it or it doesn’t apply

There are 3 areas of Physics.

I fall into the first area, Applied Physics and partially the second, Experimental.  I fall into those areas because I need to be able to repeat my findings and expect them to remain the same.  Any change is an indicator that the system has changed.

Theoretical physics is sorcery.

Still interested in College ? Study either liberal arts, biotech or a robotic engineering.

if you you still interested in college for yourself or advising someone else, then take

  • Liberal arts where you study human nature
  • Biotech as we are still carbon based entities

Unmanned U.S. Air Force space plane lands after secret, two-year mission

Very Impressive……Very impressive !!

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.
