A Little Information for Our FilesBy Peter Coffee | Print

Too often neglected in developer education, file systems deserve more respect.Partisans of object-oriented programming, often including myself, often say that the only proper programming model is one of data structures with bundles of associated methods wrapped around them. Yes, algorithms are fascinating things, but ultimately any application that's not just part of someone's doctoral thesis is going to do something to something else.
Mere data-centric advocacy falls short, though, in a world of massive data collections and the need for persistent storage. Even the casual user who actually knows something about files, instead of being limited to application-imposed abstractions of "documents," has a big edge on fixing things when they break or on creating new capabilities as needed. The higher-level developer concern is to make sure that data has a safe place to live, and that means a robust (and preferably high-performance) file systembut the file system is the most neglected element of developer education, and that should change.
I got to thinking about file systems' importance with the news late last week of MacFUSE, a Mac OS X version of the open-source FUSE toolkit for implementing file systems in a user spacepulling file system conception and construction into the space of a developer's options, instead of being the kind of chunky decision that only comes at the level of choosing an entire operating system.
Normally, I close with an invitation to you to send me your comments at firstname.lastname@example.org. This is, however, the last of these newsletters that will come out under my name, at least for quite some time to come, and I'm not sure how much longer my ziffdavis.com address will be operational. Inquiries concerning coverage of products by eWEEK Labs can go to Labs Director Jim Rapoza; personal comments to me will reach me, at least for a while, at a temporary mailbox that I'll probably maintain until the end of March 2007 or thereabouts.
