Of course it is true; I saw it on the Internet. Critical thinking in the Internet Era.
with Leah Graham.
In the Communications of the ACM, May 2003.
This paper was the first to raise the concerns about our inability to evaluate the validity of what we read on the internet, many years before "fake news" became an issue. It was followed by the paper on Web Spam and Propaganda which explained how search engines were not successful in solving the problem of content quality on the internet.

Method and System for Parallel Error-Diffusion Dithering
Patent Number 6, 307, 978 Awarder October 23, 2001.
"A system is disclosed for error diffusion dithering. The
system includes an input for receiving an input matrix
representative of image data, and a plurality of processors.
The plurality of processors processes the input matrix and
provides output data. Each of the processors is in communication
with at least a portion of the input matrix. At least one
processor processes a portion of the input matrix defined
at least in part by a substantially diagonal edge within
the image matrix."
This work is expected to lead to inexpensive faster printers and larger monitors.
