A Short Explanation
What kind of a weird post is this?
MeanMesa wrote a book several years ago, and -- thanks to switching computers. operating systems and drawing programs -- many of that book's diagrams are now "trapped" in a giant pdf format drop box file. The posting of these images [screen shots from the pdf file] is a test of blogger's graphic handling abilities. Since the text on the diagrams is turning out more or less legible, the plan to attempt to post the whole thing can progress.
If the entire book can be uploaded and posted on blogger, visitors here will be able to read the whole thing. Once it is posted, there will be a link made available here at SHORT CURRENT ESSAYS.
