Google Releases FUSE For Mac OS X
Google’s Amit Singh, on of their Mac engineers, has released a Mac OS X project he wrote as an open source contribution to the user and developer community. Called MacFUSE, it is a Mac version of a mechanism that has been popular in Linux, a Filesystem in User Space (not sure where the “E” comes from).
The basic idea is that it allows programs run by non-priveleged users to create a virtual filesystem in their user space, so that the program can use a disk drive without actually using it (since it’s all virtual), thus keeping the system more secure, and the program running as it should, regardless of who is running it. I know Internet Explorer in Windows Vista uses some sort of similar feature, but I’m not sure at what level it goes, or if other programs in Vista use the same security measure.
