The late Howard Zinn's book, "A People's History of the United States", will help you understand US history. It also helps place current political and social threads into the context of history. Highly recommended.

David A's Water Use

California is in a drought right now and water is expensive, so monitoring water use seems like a good idea. Over the last (mumble) years we have had pipes break a couple times and major amounts of water were expended, which is quite expensive and irresponsible ... another reason to monitor continuously.

Water use is automated using EKM Metering devices: water meter, pulse counter, and serial-to-ethernet converter. The simple software 'glue' I wrote to make the water data visible (coded in C and Python and using xml) is Linux/Unix centric and will require extra effort to use it on some other OS. See ekmexample-2014-10-19.tar.gz , a 15KByte gzip tar file containing the source code.

Rainfall is monitored with a simple plastic collector ($2USD at a local hardware store) graduated in inches and recorded & emptied each morning.

2016-2017 winter season rainfall at home: 14 October to 16 April: 56.5 inches.

2015-2016 winter season rainfall at home: 9 November through April22: 34.8 inches.

2014-2015 winter season rainfall at home, 20 November to 24 April: 25.8 inches.

June 21-29, 2015 we had a 25-year-old plastic water pipe break underground. Estimate of leak: 4K gallons. Should have noticed before the 29th, but we were too busy. July 1 I implemented an automatic email to ourselves in case water use exceeds expectations.
