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 How to scale/resize a box in plain TeX?
@AlexG \rlap is just one part; one should add also \smash in order to remove height and depth. I'll add it.

comment Why am I getting a “perhaps a missing \item” error in my custom epigraph environment?
I don't understand what \raggedleft is supposed to do, as I see no difference with or without it; but enclosing it between \begingroup and \endgroup is surely wrong. Think about it: an end of paragraph command has issued by \end{epigraph} when the group is already ended together with the effect of \raggedleft. Try \begingroup\raggedleft Something\endgroup\par and see: the only visible effect is the missing indentation.

comment Equation connected by lines
How come I didn't see this before? While I write something like this on the blackboard, I would never use it in a printed document: it's easy to lose one's tracks on a wide board, not on a finely printed document.

comment Redefine Glossary Entry
@ADP Say \@onlypreamble\renewglossaryentry in the class file, which is the standard method for disabling commands after \begin{document}.

comment Could significant speedups be gained from package code minification?
@mhelvens (Trying to write all necessary commas.) I can't understand what you mean; package loading could benefit from this process (not much, I believe), but I'd be scared by a minifier that removes a newline in situations such as \somecounter=3<newline>\cs, because this might lead to disasters.

In TeX spaces (or end-of-lines) are significant in the vast majority of cases. Comments are thrown out during tokenization and this ‘throw out’ operation takes a negligible amount of time, compared to macro expansion and command execution.

comment Alphabetic sorting fails in biblatex when defining characters with \newcommand
@Sverre If you are concerned with sorting, just say \newcommand{\auppercaseacute}[1]{\char"00C1} and use {\auppercaseacute{A}}rnason in the .bib file. But I'd not worry too much: if somebody is UTF-8 impaired it's their fault.

comment Alphabetic sorting fails in biblatex when defining characters with \newcommand
@Sverre Biber prints nothing, it just writes a file where \auppercaseacute appears and is then expanded by TeX at a later stage. It can interpret \char"abcd sequences for sorting, but it's another matter.

comment Alphabetic sorting fails in biblatex when defining characters with \newcommand
Biber doesn't perform macro expansion. The entry is alphabetized under "R".
