Microsoft waits for death of Internet Explorer 6

With development of Microsoft's Internet Explorer 9 (IE9) browser almost complete, Microsoft announced on Friday that it is time for IE6 users to move away from the antiquated 10-year-old browser. Microsoft has replaced it with three newer versions. On a new website, "The Internet Explorer 6 Countdown", Microsoft has launched an aggressive campaign to persuade users to stop using IE6 and update to a newer IE. Its goal is to decrease IE6 users to less than one percent.

"[Ten] years ago, a browser was born. Its name was Internet Explorer 6. Now that we’re in 2011, in an era of modern web standards, it’s time to say goodbye," Microsoft says on "The Internet Explorer 6 Countdown".

Internet Explorer's market share is slipping. IE's various versions accounted for 70 percent of the market in 2009; this has dropped to approximately 56 percent today. Mozilla Firefox, its main rival, has been actively increasing its market share while the recently released Google Chrome is also quickly gaining users. PC World's recent analysis of its own web traffic statistics concluded, "Usually, Internet Explorer is the #2 browser after Firefox, but over the past 30 days it's been #3, a couple of points behind Safari-and nearly tied with Chrome. It might be a statistical blip. But if it isn't, and Chrome continues to surge, IE could fall to fourth place."

Web developers face big problems with IE6. As they design their web pages for the newer browsers with advanced web technology and geared to the newest web core markup language HTML 5, they are forced to accommodate older out-of-date technology to support IE6 users. Also, not mentioned on Microsoft's "The Internet Explorer 6 Countdown" site, are the numerous security vulnerabilities putting the browser at risk of being hacked. The Internet security firm Secunia.com, has said that as of March 4, 2011, IE6 has 277 vulnerabilities; 39 percent of these are rated "highly critical". Microsoft says that the latest versions of Internet Explorer provide the user with enhanced protection from these attacks and threats.

Microsoft's Internet Explorer 6 is one of the most successful software products ever as measured by its durability and the massive numbers of people who have used it. IE6 shipped with Windows XP, nearly a decade ago. But it has outlived its usefulness, and Microsoft no longer wants to support it.

Space Shuttle Discovery lands for final time

The Space Shuttle Discovery successfully landed Wednesday at the Kennedy Space Center in Florida at 11:57 AM EST (16:57 UTC) for what is scheduled to be the final time in its operational career.

Upon landing, the shuttle and its six-person crew wrapped up the STS-133Discovery's 39th and final flight into space. STS-133 launched on February 24, after several launch delays since last November due to numerous technical issues. During the twelve-day mission, the crew transported supplies and parts to the International Space Station (ISS) including Robonaut2, the first dexterous humanoid robot in space, the Permanent Multipurpose Module, and ExPRESS Logistics Carrier-4. mission, the

During the mission, two spacewalks were performed by astronauts Stephen Bowen and Alvin Drew to install parts and perform maintenance on the exterior of the orbiting laboratory.

Six astronauts and cosmonauts, members of the Expedition 26 crew, remain aboard the ISS to carry out a long-duration mission aboard the outpost.

STS-133 is Discovery's 39th and final mission into space, the 35th shuttle mission to the ISS, and the 133rd flight in the entire shuttle program. Discovery has docked with two different space stations, Mir and the ISS, and was the first shuttle to fly after both the Challenger and Columbia disasters. Discovery made its maiden flight on STS-41-D in 1984, having since become the most experienced and oldest surviving space shuttle, and delivering payloads to orbit such as the Hubble Space Telescope and becoming the first shuttle to fly a Russian cosmonaut into space.

Discovery, having completed its final flight, has been offered by NASA to the National Air and Space Museum of the Smithsonian Institution in Washington, D.C., to display to the public. The museum, however, is in the process of determining how to obtain the funds necessary to transfer the shuttle. A decision regarding this possibility is expected to be made in April.

A NASA commentator describes Wednesday's landing as "the end of a historic journey. To a ship that has led the way, time and time again, we bid farewell to Discovery."

Two remaining shuttle flights are scheduled later this year, STS-134 and STS-135, before the retirement of the space shuttle fleet.

High school basketball star dies after making game-winning shot in overtime

Friday, Fennville, Michigan high school athlete Wes Leonard, 16 years old, suddenly collapsed on the basketball court after making the game-winning shot in overtime. His play had cinched a perfect season for his undefeated Fennville High School basketball team before an exuberant crowd.

As Leonard lay motionless on his back, the audience became silent. A witness on the court said Leonard had ceased to breathe and his heart had stopped. Attempts to revive him failed and he was transported to a nearby hospital where he died a little over an hour later. An autopsy revealed that Leonard had an enlarged heart, causing the cardiac arrest that killed him.

It is unclear from media reports whether the school had an automated external defibrillator (AED) available for emergencies, or if the ambulance personnel had employed such equipment. Also unknown is how much time elapsed from the moment the player collapsed until the time a defibrillator was employed. 

Many schools have acquired defibrillators for such emergencies, according to Michigan High School Athletic Association spokesman John Johnson. He said the devices at schools are not mandated by law nor by the association's regulations. There is evidence that if, in the first 10 minutes of a cardiac arrest, an AED is used, up to 80% of the victims can survive. Emergency responders usually need at least seven minutes to arrive on the scene.

News media describes Leonard’s death as shocking the community. His coach described him as a healthy and disciplined athlete who was the top scorer on his basketball team as well as the quarterback of the school's football team which won its conference's championship this season.

Dr. Marc Lahiri, a specialist in disorders of heart rhythm for Detroit's Henry Ford Hospital, said that detecting underlying heart abnormalities is difficult and such defects may not become apparent until the occurrence of a sudden and perhaps fatal event. 

Lahiri said many doctors are encouraging schools to make extensive testing of the heart routine for physicals given to school athletes. Such testing is controversial, not only because of the cost but because of possible false-positives that may lead to the need for additional testing.
