Beta Safari surfing

This week, Safari Beta 4 and Ubuntu 9.10 -- Karmic Koala got launched, the release of Office 14 got delayed, while Adobe was busy fixing vulnerabilities in its software.

Apple has released Safari 4 Beta this week, equipped with a number of enhancements that will benefit both web developers and regular users. The most visible changes to the interface are the ability to flick through browsing history, like you would flick through a book and a feature called TopSites, which arranges the websites you visit most frequently in a grid.

On the performance side of things, the new Safari is noticeably faster, thanks to a new JavaScript engine called Nitro that challenges Google's Chrome.

Web developers will be happy to know it also passes the Acid 3 test and supports CSS 3 and HTML 5.

In the world of Linux, Ubuntu got a new addition to its zoo, called "Karmic Koala". Ubuntu 9.10 takes advantage of cloud computing through Amazon's EC2 API.

Those waiting for the next version of Microsoft Office won't be getting it this year. The most significant change expected in the new release, currently known as Office 14 will be the addition of web-based versions of the desktop Office programs and compatibility with Linux machines and the iPhone.

Adobe has been busy developing security patches this week, as vulnerabilities were discovered in Flash Player 10 and previous versions, along with Adobe Reader 9 and Acrobat 9. The Flash flaw has been fixed, while the latter two are expected to get patches by March 11.
