Spanish springs. Just sad. As in trump sad. But very very American.
Which makes no statement about whether someone else does. It’s like me sayin there are no tapes of my phone and I made none knowing full well NSA tapes everything on my phone and died the taping). But “i” don’t … Continue reading
Periods doubling due to non linear feedback is standard fare. But now advance you thinking and view the non linear component of des (and any feistel cipher) as composing two digital streams to create a non linear mathematical medium , … Continue reading
Who are the four knights in America? Nsa head – Henry’s spymaster (domestic and foreign) Cia head – Henry’s assassin and torturer Fbi – Henry’s secret police (for nobles) Irs – Henry tax collector Given Washington’s intentional creation of a … Continue reading
For a high end brand, doing excellent chiropractic care, its sad. Sad as in scientology sad. Don’t be duped on the corporate practices in (non insurance) billing. It was interesting how for six weeks folks lied (badly for the most … Continue reading
I’m not the likeliest fool doing crypto. But when you goto a uni whose cs dept (of which you are a member) is part of a distinguished stats dept, and half the fathers of your co-stufents work at gchq (or … Continue reading
Turing understood the critical differences between the terms in the title. And he understood their differences relevance to the design of cryptanalysis methods. We already saw how in affine combination spaces one can calculate likelihood functions in terms of log … Continue reading
I’ve never understood, till now, the cryptographic significance of Turing (in his on permutations paper) of introducing the non ablelian quaternion group. If u look at the four 1 dimensional representations of the quaternion groups, one has all four combinations … Continue reading
I’ve now understood more of turings design, in his on permutations paper. It’s common to use Q as the letter for positive definite forms. And one then uses it to average over the group. There are many Q, since the … Continue reading
https://golem.ph.utexas.edu/category/2016/06/how_the_simplex_is_a_vector_sp.html Nice easy thinking about relating vector spaces to the probability simplex. Same as McCullough but easier!
Wish I’d known this before reading the tunny report. At the same time, it’s fascinating to see how folks in 1940 arrived at the same theory The rest of the series looks just as interesting.
Why do physicists despise Clifford algebra? Because it opens their field to a hundred million open minded computer science students, eager to unify. Put Clifford algebra into the heart of year two cs math, its game over.

Wish there were more papers written like this!
Second opinion rules ;in ca) nv won’t be much different
Page 14 is almost exact Turing Now we know why!
