I guess I can comment on some of this. semerikov is not me. So either (a) somebody else posted this, or (b) the "last edited" portion was changed by someone editing it. I notice the posted version has output for each cell, which is not how the "original" of this is/was distributed.
I post my "polished" worksheets on my own web site, and replace them with updated versiopns there. David Joyner likes to sweep them into a directory of teaching materials he maintains. Some folks, myself included, like to post experiments or half-finished work as published worksheets. It'd be nice to easily remove these, though a post to sage-notebook suggests this doesn't always work: http://groups.google.com/group/sage-notebook/browse_thread/thread/4746487e5a9f2279 So I guess what I'm trying to say is I think a lot of the published worksheets are not recent, or final versions. But the converse is true, there are some very interesting things to find there.
