Do you know about facebook?



Facebook was originally named TheFaceBook and it was developed
by Harvard student Mark Zuckerberg. The first use of the
FaceBook was on the Harvard campus and it was limited
only to Harvard students. Soon the FaceBook spread like
wild fire around the other major U.S. Universities. Mark Zuckerberg
dropped the Harvard and pursued his facebook dream to become
one of the 4th most-trafficked websites in the world with more
than 90 million active users. The FaceBook website is built on PHP-MySQL
technology and it is probably the most popular PHP website ever built.
Interesting fact is that the facebook.com domain was purchased for $200,000
and FaceBook has more than 24 million photos uploaded daily.

Swine Flu



Swine Influenza (swine flu) is a respiratory disease of pigs caused by type A influenza virus that regularly causes outbreaks of influenza in pigs. Swine flu viruses cause high levels of illness and low death rates in pigs. Swine influenza viruses may circulate among swine throughout the year, but most outbreaks occur during the late fall and winter months similar to outbreaks in humans. The classical swine flu virus (an influenza type A H1N1 virus) was first isolated from a pig in 1930. The 2009 flu pandemic is a global outbreak of a new strain of influenza virus, officially named the "new H1N1", first identified in April 2009, and commonly called "Swine flu." It is thought to be a mutation of four known strains of the influenza A virus, subtype H1N1: one endemic in (normally infecting) humans, one endemic in birds, and two endemic in pigs (swine). Experts assume the virus "most likely" emerged from pigs in Asia, and was carried to North America by infected persons. There is also evidence that the new strain had been circulating among pigs on other continents for years before infecting humans. But transmission is human to human, with cooked pork products safe to eat as the virus cannot be transmitted by eating foods. The virus typically spreads from coughs and sneezes or by touching contaminated surfaces and then touching the nose or mouth. Symptoms, which can last up to a week, are similar to those of seasonal flu, and may include fever, sneezes, sore throat, coughs, headache, and muscle or joint pains. The Centers for Disease Control and Prevention (CDC) notes that most cases worldwide have been mild so far and most hospitalizations and deaths have been of persons that also had underlying conditions such as asthma, diabetes, obesity, heart disease, or a weakened immune system. So far, over 200 000 people have been infected with Swine Flu, while "only" about 1 600 have died, which is mortality rate of 0.8 percent, so we should not panic, but we should be cautious. Compared to Black Plague pandemic between 1348. and 1350. in Europe, which had mortality rate of over 75 percent, Swine Flu is not so scary, isn't it?
