Name the Open Source Project!
That is 429.3 MB in size and requires Visual C++ 2005 to build on Windows. The new open source browser from Google is called Chrome and is initially only available for Windows. The open source project is called Chromium and features a very colorful waterfall- this shows the current state of the Chromium build, in subversion and whether you can get a successful build or not.
One of the main features of Chrome is that each tab runs in a separate process with hidden tabs running at lower priority. So debugging can be interesting but it's well documented in Google's excellent docs. Chrome has a plug-in architecture as well which isolates all plug-ins in their own process. This might crash the renderer but won't hang Chrome. I've been playing with this browser and am very impressed with its speed. There is only one thing that will stop a number of Firefox users migrating to it and that's all the handy add-ins they have, at least until Chrome alternatives are produced. The built in task manager and "Stats for Nerds!" in Chrome are kinda cute! As usual there's a link in the C++ code library.
Interesting Stats In the initial Chromium download project sources files there are 110,214 files of which 8,332 are C, C++ or header files! This is an industrial sized open source project!
According to the Google literature, each tab runs a seperate process, not a seperate thread.
