DVD concept invented in the 1930s?

I had heard that the FAX machine was created long go, in fact it existed before workable telephones (strange as that seems.) But this blows me away. It is a concept drawn in 1932 of recording video to records. It appears to use a rotating disc with holes in it to break the information up into pixels, then each pixel is read by a photo receptor and that information is recorded to the record. It's incomplete and they admit it is just a concept, but wow... it is very much a description of how DVDs work. Check out the rest of the site, there are all kinds of interesting things from that era. From the frightening (bathing limbs in tubs charged with electrical current to treat illness) to the amazing (precursor to the defibrillator.)

Our greatest fans: we'll see you in court

The last Harry Potter book arrived at stores with every bit of fanfare and excitement that was expected. Amazon pre-sold more than 1.3 million copies which is unheard of for the release of a new book.

I often promote the power and promise behind the web and the millions of people who use it passionately every day, so I was not surprised when I heard that a bilingual fan had created a Spanish translation within days of the book's release. Others underwent similar efforts for other languages. Rather than admire a level of devotion and dedication to a product that is so strong that people are willing to spend untold hours translating it so their friends can access to it, the book's publisher has opted to sue the 16 year old student who did an unauthorized French translation. When are big corporations going to learn that suing your fans is not conducive to your relationship with them? Surely every Harry Potter fan who reads those translations will buy the book anyway, if not to read the official translation, then to have the book to add to their collection. It was something that spread the excitement far beyond the English speaking world at no cost or harm to the publisher. I hope they realize their mistake , apologize and drop the case.
