This was a fantastic display of four seasons projected on the
Chapelle St Etienne de Beaune (Côte d'Or), a building in Beaune France. We were at first amazed at the artistry and creativity, and weren't sure that is was the wine from dinner ....

Global Warming Calculation
I googled "Global Warming Calculation" to try to find out how much "man-made" activities are actually heating the earth. I could not find any. The idea to actually do the calculation happened over drinks when there was a lot of conversation about "of course man-made warming is real".
I pictured millions of homes burning oil, cars, truck, etc. and wanted to know what effect they have as "thermal pollution". In my mind, they would have to, but alternatively, once I am outside my house, I cannot feel the heat inside even though I know that all that heat eventually leaks outside (otherwise I would only have to heat my house once for the winter!).
I got tired of the Global Warming "Debate" based on "feelings", mine as well as others. That is when I decided to use some simple math.
So I decided to calculate how much energy it would take to heat the Earth's atmosphere one degree. It turns out if we take all of the oil produced for 56 years and burned it (assuming 100% efficiency and 100% heat retention) we could raise the temp of the atmosphere 1 degree.
Here are the calculations, which I think are accurate to within 10% (+ or - 6 years). These numbers do not prove or disprove "Global Warming", but are simple data that I thought was missing.
The Mass of Atmosphere (in kilograms) x energy needed to heat one kilogram of gas one degree.
The answer is: 9.46 x10^21 Joules.
Worldwide, 84.455,000 barrels of oil is produced daily. That is 1,294,695,150,000 gallons per year. Oil contains 1.3x10^8 Joules per gallon, making the energy 1.6831E+20 Joules per year.
Dividing 9.4576E+21 by 1.6831E+20 gives 56 years to heat the atmosphere 1 degree.
Here are the calculations:
Total Worldwide energy produced by burning all the oil produced:
Total Amount of energy needed to heat the Atmosphere 1 degree. 1840 is the specific heat of air in joules.
Dividing these numbers, we end up with years:

New Notes App Store
Vibrant Apps Community
The point of NotesAppStore is to show that there is a vibrant community building customer-tested apps for Lotus Notes. Anyone looking at Google apps can find many comparable apps in Lotus Notes. However, the Lotus Notes apps are more mature and have been field tested, some for many years. The variety and functionality of these apps also is unrivaled by anything Google offers to businesses.
The other huge distinction is vendor support. Most of the vendors in the NotesAppStore are small to midsize businesses (SMB) who are available to help install and support their Apps. They will answer the phone. This excellent app support will be critical when there is a problem. And they have references to prove it!
NotesAppStore Site Features
Under the Company Listing, I put all the Twitter name and company blogs that I could find, along with a link to the management page of each website. Again, most of these Lotus Notes App vendors are approachable leaders of small to midsize businesses who are quite visible in the Lotus community.
You can also Search for anything on the site.
There is also a place to Recommend an App and another place to Post a Comment to help make the site more useful.
So, Lotus Notes and Domino users, finally we can say "There is an App for that" !
