Water Conservation Showcase

Attended the "Water Showcase" recently, hosted by PG&E in San Francisco.  Quite the popular event as there was a good line of people waiting to get in before they opened the doors.

There were lots of exhibitors, showing how their wares would help save water or make watering your landscape easier or how solar heating of water can be setup.  And the presentations were also well attended.

Why do we have Lawns?

Why do we have lawns?  In much of the USA, it is expected that homes shall be landscaped with lawns in front and back.  The idea of lawns seems to come from royal estates in Europe that had the money and manpower and acreage to contain large expanses of manicured grass. It was a place to relax or sometimes march army squads for review and inspection or maybe it was a hunting green or play area.  Large lawn space also became popular as common grounds for other formal and informal gatherings; to have political discourse or hear music or enjoy picnics.

Where's the Rain?

When I was growing up, it seemed like the weather was usually pretty predictable; rain would start coming in late September or in October, then be off an on until April.  It would fill the reservoirs in the area and leave plenty of snow pack in the Sierras.  The spring and fall would be mild with warm to hot days in the summer.  What I really liked in the summer was the morning fog that had been pulled in from the ocean by the heat of the previous day.  That heat was usually farther inland so that our farm was right in between the breezy coastline and the hot inner valle

Global Corporate Power

Over history, man has frequently given control of individuals lives to some power.  Kings, rajas, dictators, pundits, governments..... they all have or had some control over the individual and how that life will be lived.  Now we seem to have corporations that control our lives.  And on the global scale.

What is Zero Net Energy?

I just attended a one day class regarding zero net energy. Turns out there are at least four ways to define this. It can be as simple as getting your power bill to zero by feeding in enough on-site-produced energy to zero out what you use from the grid. OR you can be zero net energy if your produce enough on-site energy to cover the amount of fuel it actually takes to produce the off-site energy you use.

OpenCart - Alert on store actions

As I start testing out OpenCart, I ran into one issue. When a customer puts in a request for a return, no email is sent to alert the store admin or any one. So I started looking around for solutions and ran into couple of suggestions on OpenCart forum. Below are my variations which I am contributing to OpenCart community for free as this is not my original work.

Objective: Email alert sent on request for return

Step 1: Look for file

Shopping Cart for E-Commerce Website

I have started playing with various open source e-commerce shopping cart systems available out there. I thought it would be good to document my experience as I go along. After Googling around, I ran into a page at Wikipedia which lists quite a few of them (both open source and paid). I will start working with some popular free ones in random order and compare them. It seems like osCommerce is used by a fairly large group. So I will get started with that and see how it goes.

Photography is an Art

Snapshots are a quick way to record memories in our lives. They remind us of exciting events, letting us relive those times. But they usually don't mean much to other people outside of the taker's family and close friends.

Photography is an art form; painting with light to draw out the feelings of a scene. A fine photograph conveys not only content but emotion. Who can deny the powerful effect of Ansel Adams' work (www.anseladams.com)?
