MacFUSE. Please Note: This project is no longer being maintained. We cannot currently help with any lion (or any large feline) related bugs or issues. The MacFuse google group is a decent resource for finding forks/replacement projects. MacFUSE allows you to extend Mac OS X's native file handling capabilities via 3rd-party file systems. It is used as a software building block by dozens of products. As a user, installing the MacFUSE software package will let you use any 3rd-party file system written atop MacFUSE. As a developer, you can use the MacFUSE SDK to write numerous types of new file systems as regular user-mode programs.
In more technical terms, MacFUSE implements a mechanism that makes it possible to implement a fully functional file system in a user-space program on Mac OS X (10.4 and above). The MacFUSE software consists of a kernel extension and various user-space libraries and tools. To see some examples of MacFUSE at work, see the videos linked on the right. Big Robot.

Ontology is Overrated: Categories, Links, and Tags This piece is based on two talks I gave in the spring of 2005 -- one at the O'Reilly ETech conference in March, entitled "Ontology Is Overrated", and one at the IMCExpo in April entitled "Folksonomies & Tags: The rise of user-developed classification. " The written version is a heavily edited concatenation of those two talks.
Today I want to talk about categorization, and I want to convince you that a lot of what we think we know about categorization is wrong. In particular, I want to convince you that many of the ways we're attempting to apply categorization to the electronic world are actually a bad fit, because we've adopted habits of mind that are left over from earlier strategies. I also want to convince you that what we're seeing when we see the Web is actually a radical break with previous categorization strategies, rather than an extension of them.
PART I: Classification and Its Discontents # Q: What is Ontology? And yet. Domain. GeoOntologies. We've created three ontologies for geoStuff which express a base set of geographic features such as countries and cities, their spatial descriptors such as points and multipolygons, and relationships between these spatial descriptors, as described below. Although it would be nice to translate the OGC's official GML specification to an ontology, none of us have a spare lifetime or two. Here is a sample mapping of GML to our ontology . There are also samples in the ontologies themselves. For versioning, the latest version of each ontology can be linked to by the following links. The person to yell at for this (preferably with helpful suggestions) is Femke geoFeatures The geoFeatures ontology specifies some key geographic feature classes as well as classes for describing their spatial characteristics.
