какой-то conspiracy theory blog получается

Last year, an article in PC World magazine pointed out that printouts from many color laser printers contained yellow dots scattered across the page, viewable only with a special kind of flashlight.

Yesterday, the Electronic Frontier Foundation, a San Francisco consumer privacy group, said it had cracked the code used in a widely used line of Xerox printers, an invisible bar code of sorts that contains the serial number of the printer as well as the date and time a document was printed.
.
The EFF said it has identified similar coding on pages printed from nearly every major printer manufacturer, including Hewlett-Packard Co., though its team has so far cracked the codes for only one type of Xerox printer.
.
And it's not as if the information is encrypted in a highly secure fashion, Schoen said. The EFF spent months collecting samples from printers around the world and then handed them off to an intern, who came back with the results in about a week.

It turns out the two technologies that are changing the world for the better are information technology and biology. Biology's going to give us the medicine to solve these diseases, the tragedy of those things. Information technology is a leveler. It takes any political repression that people try and makes that virtually impossible. It lets curious kids have way more material that even I had as a very privileged student some time ago.
These are two areas where you can have jobs that pay well, jobs that are interesting, and jobs that impact the world in a very positive way. I think...those are the two ways the world is changing and not many other ways.

да, но не всё так просто. information technology нам уже приносит сюрпризы, и биология тоже думаю ещё принесет
