Brian Kernighan’s declaration in the SCO lawsuit is not to be missed. Aside from the technical conclusions, Kernighan’s qualifications are an interesting read (even if they are written with excess humility). IBM paid him $400 an hour for his time. His basic conclusion is summarized as follows:

If unprotectable elements are excluded from the comparison and an appropriate standard of similirity is applied there is no similarity between the six parts of Linux identified by Mr. Gupta and the allegedly copyrighted works.

I wasn’t surprised that SCO’s claims were spurious, but I was surprised at how little they are claiming.
