You're fired: What it costs to sack a worker

After years of fat profits and bonuses, cost-cutting is once again at the top of the corporate agenda. For companies wanting to chop out middle-management dead wood or sack factory workers, costs can vary enormously across the world. America, New Zealand and Tonga are among the most company-friendly countries, requiring no penalties or compensation to fire a full-time employee of 20 years. By contrast, a business in Zimbabwe must shell out well over eight years' worth of pay to sack a worker. But companies in Venezuela and Bolivia are even more tied—workers there cannot be fired at all.

NASA Remembers 9/11

"The world changed today. What I say or do is very minor compared to the significance of what happened to our country today when it was attacked." So said Expedition 3 Commander Frank L. Culbertson, upon learning of the Sept. 11, 2001, attack on the World Trade Center.

This image is one of a series taken that day of metropolitan New York City by the International Space Station's Expedition 3 crew that shows a plume of smoke rising from the Manhattan skyline.

Upon further reflection, Commander Culbertson said, "It's horrible to see smoke pouring from wounds in your own country from such a fantastic vantage point. The dichotomy of being on a spacecraft dedicated to improving life on the earth and watching life being destroyed by such willful, terrible acts is jolting to the psyche, no matter who you are."

Here comes Google Chrome...

On the heels of launch of Firefox 3 and IE 8 Beta launch, comes the news of Google's own browser - Google Chrome. Google has used altogether a different strategy to announce the launch - it released a comic book for the same. Certainly Google want to show that it is a fun tool, and there is still room for it in the browser space (despite the furious battle between Microsoft IE and Mozilla Firefox).
Chrome seems to have a fresh approach to browsing tools, and a new set of features. With the IE 8 in beta, and Firefox 3 going strong, it looks to be a good season for innovation on the Web.
