comment spam

The war on comment-spam has now begun. It appears that Blogger might have some anti-spam measures of which I was unaware. Otherwise it’s a strange coincidence that I get a huge number of comment spams for extremely hard-core porn from the Ukraine so soon after starting a WordPress blog.

About 24 hours before the spam [...]

WordPress gives me the power to change all aspects of my blog’s operation (including adding plug-ins). [...]

paper about ZCAV

This paper by Rodney Van Meter about ZCAV (Zoned Constant Angular Velocity) in hard drives is very interesting. It predates my work by about four years and includes some interesting methods of collecting data that I never considered.
