I'm a mathematician working in algebra. I've been using TeX since 1987, but couldn't write my Ph.D. thesis with it. Sob!

I teach LaTeX at my university, besides the mathematics courses. I'm the author of some LaTeX packages and even of one Plain TeX package. At my site it's possible to download my book on LaTeX programming (in Italian, sorry).

Here's my motto for TeX.SX:

Pronto prontissimo son come il fulmine: sono il factotum della città. (From "Il barbiere di Siviglia", music by Gioachino Rossini, libretto by Cesare Sterbini.)

comment Is there a way to avoid short lines?
Suppose you have a two line paragraph with only one word in the second line. It's quite improbable that another word can be accommodated in the second line without stretching too much spaces in the first line. Even adding ties would not help, because TeX might prefer hyphenation, if the alternative is worse, based on the current parameters. Only long enough paragraph allow for tricks like those outlined in the linked answers. Or a ragged right setting, of course.

comment Font Rendering Artefacts on OS X
I'm not experiencing them; I rarely use Preview, preferring Skim, which however is based on the same PDF toolkit as Preview. It may happen that under certain conditions rounding can cancel some pixels or misplace letters, particularly at small magnification.

comment language problem
@user2399518 The encoding is LGR; but there are not many fonts available with that encoding. Surely Helvetica (phv) isn't.

comment Creating pagerefs referring to article version in beamer presentation
The package xr allows this, but obviously you have to use a different filename for the article and the presentation, or the .aux file would be overwritten. At least you have to rename the .aux file you get after the final typesetting in article mode.

comment Underlining fractions
This is surely not a MWE. I get regular double underlining if I use \underline{\underline{#1}} in the definition of \ans. The obvious problem is that the "tikzmark" is placed at the baseline.

comment \setbox containing maths interferes with surrounding math mode in XeTeX
With LuaTeX the dimensions are 3.93999+3.45. You also need to define \scriptfont1 for getting characters in the formulas.

comment \setbox containing maths interferes with surrounding math mode in XeTeX
It seems that XeTeX sets some parameter only when the first math formula containing a character is typeset. I get 3.93732+3.44841 if I typeset that with pdftex

David Fuchs' article is actually a description of the format, starting from the division into bytefields.

@user18921 This may depend on the PDF viewer and on OS settings. On Mac OS X it works out of the box.
