„If the image is subsequently modified, the reader software (on the PC) detects that the checksum does not match. What I like about this solution: * It addresses a real need within a target niche * The technology involved is really simple * It's low cost to implement - involves only software * Creates a differentiator in a rapidly-commoditizing space * Creates lock-in Obvious extensions of this idea - surveillance video cameras, digital voice recorders, document integrity, etc....“

„Marguerite Nering, in her University of Calgary thesis, has done an excellent job providing a thorough description of pitch. She says, astutely, "To understand perfect pitch, one must understand pitch," and she dedicates fully 61 pages of text to that exploration even before beginning to consider absolute pitch and her own experiments. Although Richard Feynman would undoubtedly shake his head at my using Nering's report as a secondary source in describing the concepts of "pitch" to you, the body of information Nering has assembled to describe pitch appears to deliberately avoid a definitive single answer to that question, but attempts instead to impress on the reader that "pitch" is a remarkably versatile and incredibly misunderstood word.“http://www.aruffo.com/eartraining/research/ phase4.htm - Cached
„> Hopefully, it will be modified in light of the flaws Stevan pointed out> in his critique of it, chiefly by a correction of its mistaken aim of> undertaking journal reform, as distinct from providing facilities> supporting journals in going on-line properly. This is incorrect. The correction was not just to drop journal (peer review) reform and "instead provide facilities for journals to go on-line properly"!“http://www.nih.gov/welcome/director/ebiomed/ com0801.htm - Cached
„What NEED does this meet? Everybody wants to contribute to the world of science, I guess, if they can. Not everybody has all the credentials, contacts, energies and so on available to go through the entire process of getting something formally published in a paperbased scientific journal, or even an electronic scientific journal.“http://mysociety.blogs.com/mysociety/2003/12/ the_official_da.html - Cached

„This marks the first time that any common PC operating system, either desktop or server, will include a hardware accelerated, universal display driver as part of the base operating system. Until now, operating system vendors have had to rely on overtaxed graphics hardware vendors to provide software driver support, resulting in inconsistent driver quality and infrequent or non-existent updates for the installed base of graphics hardware.“http://www.os2voice.org/vnl/past_issues/vnl1099h/ vnewsn4.htm - Cached
