The book is a physical reality

The Universal Machine

On Sunday April 4 2010 I started this blog; the first post was "Welcome." which said:
"Welcome to the blog of the writing of the Universal Tool
I've been writing a book, on and off, for several years now. The book is intended to be a popular science book about the history of computers. I'm a computer scientist by profession and so I've long had an interest in this subject.
   The idea of this blog is to encourage me to keep working on the book by being able to share both the process of writing it and elements from it with who ever decides to follow the blog of just drop by."
    Yesterday I printed out the entire book for the first time. It's a strange feeling seeing the book's manuscript sitting there on the table. Strange but good. Incidentally the blog has been very useful in writing the book.
