Slurs and ad hominems noted. I take it you decline the challenge. Why am I not surprised? Channeling the unquestioned, indefatigable computer expert Ms. Zebest, she awards you, professor, the grade F for Fail.
Slurs and ad hominems noted. Sorry, but pointing out that a self-proclaimed expert is no expert is not an
ad hominem attack no matter how much you fervently try to make it so.
It's not a "challenge" -- it's yet another obvious Birther attempt to shift the burden of proof in the face of embarrassing and obvious failure. And you've fallen for it, naturally. Of course, the courts don't fall for it. That's why Mara Zebest's bluster and handwaving never make it beyond the bulletin board at the Maricopa County sheriff's department.
Zebest's first offering was an attempt to show that the Obama PDF was anomalous for the features she named. Little did she know it would turn into an exercise showing how little she new about PDFs. As I've lectured you for months now: an anomaly is a departure from expectations. Whether an anomaly has meaning depends on whether one's expectations are properly informed. Hers aren't, so her "anomalies" are simply examples of normal behavior.
And again Zebest's demand for replication are just Zebest's Ignorance 2.0. She's still trying to parlay the notion
again that there's something wrong with the Obama PDF, not something wrong with Mara Zebest's understanding of computer science. After having fallen flat on her face, she stands up, brushes herself off and willy-nilly invents a whole new test for document authenticity, with no basis in science or practice, and now demands that this and only this is the litmus test for Obama's PDF.
Honestly who do you guys think you are? Your entire case is simply making up new rules. New tests, new legal theories, new requirements -- all for the purpose of going after
one sitting President. Why, because the candidate has already passed all the normal tests applied to everyone else, and you need something new to continue your irrational hatred.
If I were sitting on Mara Zebest's graduate student committee (and I've done dozens of those), she'd be sent back to work on her methodology. This is why real scientists with real education and real, pertinent professional expertise are accepted in court, and artists who write books on how to make pretty Photoshop pictures are not. The part that's missing from her
challenge backpedaling is her demonstration that this is a valid test for authenticity. That is, she hasn't show that
real scanned PDF documents would be reproducible according to her expectations while a "digital forgery" would not. She hasn't tested her new test. Hence she can't demand that everyone else use it as a yardstick.
While neither you nor Zebest seems to know what combinatorial complexity means or how it affects reproducibility, I assure you a court will know and care. And contrary to your premature attempts to write me off, I
have done many experiments to study how reproducible a PDF scan and optimization exercise is. So yes, I decline to take her challenge because I already proved its invalidity weeks ago, and because (as usual) I don't fall for feeble attempts to shift the burden of proof. You responded with silence when I made those demonstrations.
You, on the other hand, haven't answered a single challenge or question I've put to you that requires you to take practical action or demonstrate practical understanding. So stop trying to hide behind Zebest and start paying attention. As I said before: try again, student.
Now if you're just going to continue stomping and whining that I won't take your little toy pseudo-expert seriously, then be my guest. I've already explained at length to everyone just how wrong she is. So as long as you continue trying to drag the discussion around in circles, you're going to be dealing with me outsmarting both her and you.
