Interestingly, back in 1982, A. M. Odlyzko, of AT & T Bell Laboratories, published a document entitled “Discrete logarithms in finite fields and their cryptographic significance” ( http://www.dtc.umn.edu/~odlyzk... ). Page 63 of this document presents a weak form of the DLP, namely a^3 = b^2*c (mod p).
It seems then, that the National Institute of Standards and Technology (NIST), driven in turn by the NSA, have required that compliant curves have this potentially weak form of the DLP built in; merely transposing the layout of the formula in order to obtain what little obfuscation is available with such a short piece of text.
I can virtually guarantee if you were inventing the first character set today, with no backward-compatibility constraints and no knowledge of the real world's history of keyboarding, you would not include a tab key.
An indentation level key. I think I would like that. Put it on the list. Scroll Lock on the other hand...
Are you kidding? If you edit code on unix tabs are a nightmare.
I edit code on Unix all the time and have no problem with tabs.
Guys  usually fell into two categories, the electrical or mechanical.
Yep, those were the two categories I fell into.
