V!NCENT writes with an excerpt from a new publication by Microsoft: "As web sites evolved into dynamic web applications composing content from various web sites, browsers have become multi-principal operating environments with resources shared among mutually distrusting web site principals. Nevertheless, no existing browsers, including new architectures like IE 8, Google Chrome, and OP, have a multi-principal operating system construction that gives a browser-based OS the exclusive control to manage the protection of all system resources among web site principals. In this paper, we introduce Gazelle, a secure web browser constructed as a multi-principal OS. Gazelle's Browser Kernel is an operating system that exclusively manages resource protection and sharing across web site principals." Here's the full research paper (PDF).

It's been a couple of years since Apple ran their Switcher ads — but folks are still making the switch. Rockgod writes to point us to his list of pros and cons after he switched from Windows to Mac recently.

Since then, I have been a sucker for every upgrade — 95, 98, NT 4.0, 2000, XP... I bought the cheapest Mac available, a Mac Mini with a single-core Intel chip and the minimum of RAM — 512 MB. It cost me AU$949. Since plugging it in, I have barely used my $3000 Windows desktop... All this time later, I have almost exclusively switched to the Mac."
