An incomplete study virtually guarantees incorrect use of even seemingly familiar terminology, and misunderstandings of significant practical importance.   Perhaps in lieu of listing problems individually, I can offer a couple of tutorials:

Oh come on, literally on the first page a discussion of the ins and outs of scanning EN and releasing it on CD!  We've just had that one :-D

I guess since it's your baby you get a pass on that one...
Regarding your missing rare book, I had a bloody great row with a parcel company that delivered a fortunately not at all rare book to my house - and left it in the bloody recycling bin.


As I read the article on sampling theory I can feel bits of high school calculus slowly emerging as the cathodes of dusty neurons warm up and begin to glow.  Some more of that and I might understand most of it!
