Calendar & Easter History
I was wondering how easter dates are calculated, when my friend and collegue from Romania told me he is having it on May first and that He is a Chirstian Orthodox. I was confused. I have many orthodox friends in India, they never said they have easter on another day.
When I investigated and found that easter is calcuted in 3 ways and these three ways used in diffrent parts of the world.
METHOD 1 - The original calculation based on the Julian calendar
METHOD 2 - The original calculation, with the Julian date converted to the equivalent Gregorian date
METHOD 3 - The revised calculation based on the Gregorian calendar
And the link provides algorithms for calculations for these Easter dates.

Definition of Easter Sunday Date
Easter Sunday is the Sunday following the Paschal Full Moon (PFM) date for the year. In June 325 A.D. astronomers approximated astronomical full moon dates for the Christian church, calling them Ecclesiastical Full Moon (EFM) dates. From 326 A.D. the PFM date has always been the EFM date after March 20 (which was the equinox date in 325 A.D.).
Easter Sunday date is the Sunday after the Paschal Full Moon (PFM) date
The PFM is the first Ecclesiastical Full Moon (EFM) date after March 20
PFMs are pre-defined (see above)
EFMs are approximated astronomical full moon dates, not actual astronomical full moon dates

Spotting Fake Smiles
Most people are surprisingly bad at spotting fake smiles. One possible explanation for this is that it may be easier for people to get along if they don't always know what others are really feeling.
Although fake smiles often look very similar to genuine smiles, they are actually slightly different, because they are brought about by different muscles, which are controlled by different parts of the brain.
Fake smiles can be performed at will, because the brain signals that create them come from the conscious part of the brain and prompt the zygomaticus major muscles in the cheeks to contract. These are the muscles that pull the corners of the mouth outwards.
Genuine smiles, on the other hand, are generated by the unconscious brain, so are automatic. When people feel pleasure, signals pass through the part of the brain that processes emotion. As well as making the mouth muscles move, the muscles that raise the cheeks – the orbicularis oculi and the pars orbitalis – also contract, making the eyes crease up, and the eyebrows dip slightly.
Lines around the eyes do sometimes appear in intense fake smiles, and the cheeks may bunch up, making it look as if the eyes are contracting and the smile is genuine. But there are a few key signs that distinguish these smiles from real ones. For example, when a smile is genuine, the eye cover fold - the fleshy part of the eye between the eyebrow and the eyelid - moves downwards and the end of the eyebrows dip slightly.

Enterprises Warming Up to Firebird Open-Source Database
Click here for the doc from eweek
"Firebird—an open-source relational database known for sizzling transaction performance—is surging in popularity in the enterprise and heralds growing acceptance overall of open-source databases, according to a recent study."
"The report also found that 60 percent of database developers plan to expose or invoke database operations through Web services. The most likely database operations to be invoked are stored procedures, at 22 percent, SQL Query Web services, at 18 percent, and XML Query Web services, at 15 percent."

IT'S SAD THAT TODAY'S KIDS DON'T SEEM TO BE INTERESTED IN STUDYING SCIENCE AND MATH
By Janet Perna
Some excerpts from her writing in Mercury news.
"The National Commission on Mathematics and Science Teaching for the 21st Century revealed that by 2008, the technology-driven economy will add 5.6 million jobs in the health sciences and computer industries that require science and math skills. Meanwhile, more tech workers are retiring, and precious few are ready to take their place."
"Taken together, the black, Hispanic and American Indian communities constitute only about 6 percent of the 2 million scientists and engineers in the United States."
"We can do a number of things to improve this picture. We must support national advocacy, research and policy organizations that are working to redress the underrepresentation of women and minorities in technical careers. These groups need both funding and volunteers. And companies must focus on attracting and retaining women and minorities in information technology positions."
"But most of all, parents, teachers and business leaders -- all of us -- must encourage and influence our children to take a longer view of what education has to offer, which will lead many of them to find rich and rewarding careers in math and the sciences. Tell them and teach them about the exciting opportunities that await them over a lifetime. Our nation's future success depends upon this effort."
