Google has entered the browser space. Chrome, its browser still in beta, is based on the open source Webkit project. Some will recognize Webkit as the foundation for another browser, Apple Safari. But Chrome also borrows heavily from Mozilla Firefox and Microsoft Internet Explorer, giving this new browser an old and familiar feel. There is, however, innovation. Tabs are arrayed atop the browser instead of in the traditional toolbar. And users can drag and drop the tabs on the desktop outside the browser. There is also a way to make an icon for GMail and Google Calendar on your desktop. Deep down, Google has also upgraded how the browser handles Javasript. Gone are the days when Java applets simply gave you dancing babies on a Web page. Today we're running robust applications. Joining CNET News' Robert Vamosi this week is Billy Hoffman, manager of HP's Web security group. Hoffman, along with Bryan Sullivan, also co-authored AJAX Security. In this podcast, Hoffman offers what he thinks Google did right with Chrome, and what could be trouble down the road. Listen now: Download today's podcast Less
