I did study math and had a knack for it, but I am sooo out of that business now ...

comment How to display sine squared more compactly
That raises the question, what to do if \left... \right is needed for a complicated argument? If we are lucky, it is a fraction and again paraentheses can be dropped.

comment Blur the whole document and add a demo watermark on each page
After contemplating this, maybe something totally different could be adequate (but I have no idea how to accomplish this): Replace all text in the output - except the part that shall remain readable - with blind text ("lorem ipsum") in such a manner that tha paragraph shape is not affected; a good implementation of such a method might also use "blind math" for display formulas and "blind images" for illustrations ...

comment How to add random lines over text as a watermark and anti-OCR?
Keep in mind: The better OCR development, the less human-readable is any anti-OCR text (I myself sometimes fail todays captchas!). For any text of nontrivial length, human reading becomes intolerably strenuous (not to mention the visually impaired)

comment How should I write $x^*^2$
Next to that, the third one represents the logical structure of the expression and therefore does exactly what DEK considered best for such cases (read the discussion about ${a^b}^c$ vs. $a^{b^c}$ in the TeXbook)

This is a very common method by the way

comment Icons in Table of Contents
So the icon is not supposed to occur in the section heading itself (i.e. on page 3, in the example)?

comment PDFs want to scale down
@UlrikeFischer I think the option that is selected in the print dialog is simple the one you used last. I'd be more interested in a feature that would cause no scaling even if I selct "scale to paper" because the driver should notice that there is sufficient margin. This may hoever be a dream ...

comment PDFs want to scale down
@egreg Oh, interesting. So it seems it is possible to put the information that shrinking is a bad idea somewhere. Admittedly, I just tried the same with a pdf export (from Word 2010 under Windows 2008) and that showed the same 94% problem. Can you somehow upload an A4 pdf that does not wnat to shrink so that I can test it on my system?

comment PDFs want to scale down
My hopes were that one of those PDF boxes (MediaBox, CropBox, Bleedbox, TrimBox, ArtBox, WhateverBox) just might need a kick in their butt.

comment How can I typeset a quote directly above a period?
Does the example text use this technique throughout or only (as shown) as an emergency measure att the end of a line?

comment Redefining Infinity in LaTeX
If you want to be understood by other mathematicians, use established symbols. Or do you also write ":" instead of "2" because the colon better represents two-hood? --That beng said, you might add a small white blob on top of the standard $\infty$ symbol (assuming you only write on white background)

comment How to get a properly centred horizontal rule?
I think the \hfillat the end gets eaten (and replaced with \parfilskip), henc is superfluous; in fact, if this were not the case, it would be stronger than the \hfilin the beginning!

comment Defining custom commands is bad style?
Then again, defining a shorthand for "Hilbert space" prevents "Hilbret space" typoes ...
