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 Error: paragraph ended before … was complete
@A.Ellett I find the question interesting enough. See the xparse implementation of your multipronged macro: just a tad easier. ;-)

comment Error: paragraph ended before … was complete
From the empty line after {\frac{1}{2}}

comment Error: paragraph ended before … was complete
This is always due to \par in the argument of a non \long macro.

comment Problems with acro package and greek babel?
@Aradnix I'd wait for Clemens to fix it. In the meantime you can use Mark Birtwistle's workaround.

comment Moderncv, Polyglossia and Font
I don't know what happens, but adding \normalfont after \begin{document} is a workaround.

comment LuaLaTeX, Fontspec: Wordspacing and Letterspacing
@musicman I already told you that negative letter spacing is exactly the contrary of what you should do; bigger word spacing only for small caps is something I can't understand the purpose of. Nonetheless, you seem to have discovered a bug in fontspec.

comment Multiple alignment in align environment
I'd move also the 2\sigma_{2,1}\sigma_{2,3}\sin(x_{1})u term to the next line.

comment Problems with acro package and greek babel?
This surely works provided also LGR is not loaded with fontenc prior to acro. Actually loading fontenc with the LGR option is not required any more for Greek. Very good as a temporary workaround.

comment Problems with acro package and greek babel?
Unrelated: \textgreek{...} is sufficient and \selectlanguage{greek} is to be removed as it just adds noise (and possible errors).

comment To have smaller font in this table of presentation
You need \selectfont after \fontsize{...}{...}

comment arrows with xy package
Welcome to TeX.SX! Isn't $\nearrow$ something similar to what you want?

I think you have to use Xindy and not MakeIndex.

comment Conditional statement in beamer style file
If no \framesubtitle command is given in a frame, \insertframesubtitle is equivalent to \@empty, so you might try \ifx\insertframesubtitle\@empty<code for no subtitle>\else<code for subtitle>\fi Don't use braces around the code for the true and false parts.

comment Nested environments to scale tikzpicture
The error is in using \begin{scaletikzpicturetowidth} and \end{scaletikzpicturetowidth} in the definition of bbgrid; they should be \scaletikzpicturetowidth and \endscaletikzpicturetowidth because of the peculiarities of \NewEnviron.

Can you please add an example?

comment Floats lost error
\marginpar uses the \insert mechanism; an \insert does something only if it is at the outer level, not inside a box. You may want to look at the marginnote package.

@mb21 \url has facilities for breaking at various points in the URI.

comment newtxtext and osf — turn on and off
@Sverre I used the provided text. My opinion is that before starting with using a font, several points should be well pondered. Maybe one can decide to use old style figures with Times, after all there's no font police around. But figures should be the same in the table of contents as in the document body. Using old style figures in text when several figures are used in math should be discouraged.

comment newtxtext and osf — turn on and off
Just don't use old style figures in Times. ;-) Please, try being more specific in your question.

comment newtxtext and osf — turn on and off
Old style figures in Times are an anachronism; anyway, what's the reason for wanting to turn the feature on and off?
