The next version of Windows, dubbed Longhorn, will change its permissions system to be more UNIX-like. Between this and the new shell scripting system it is slowly becoming much more UNIX-like. Pretty funny, given that they lauded for years that their way was best.
Just a quick note to say that I'm writing this from a Mozilla Firefox sidebar rather than the full editor. This is a little bar that opens on the left side of the window and allows you to do some cool things. This sidebar lets me write messages for my weblog without having to open the full administration window, useful for when I think of something quick and want to write it down. Yet another good reason to use Mozilla Firefox.
