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 Latex - Miktex cross references linking back to ref point
I think it has already been discussed: what if you use \ref{label1} twice in your document? Where would the link point? Better using the “Go back” feature of your PDF viewer.

comment Caption not compiling properly
If you want a caption to a figure, then insert the code in a figure environment.

@SeyhmusGüngören Update it.

comment Is it impossible to simultaneously use the unicode character left-to-right and the package inputenc with the argument utf8?
You have to set up TeX for supporting right-to-left writing; there are specialized packages for this, but probably switching to XeLaTeX and bidi is better.

comment keep one subfigure fixed and move another subfigure towards right
Why don't you use \subcaptionbox?

comment Broken Arrow in Lucida Bright Font
@JoséFigueroa-O'Farrill Just do \renewcommand{\relbar}{\mathrel{-}} for TeX Gyre Pagella.

@Kpym Certainly so!

comment Broken Arrow in Lucida Bright Font
@JoséFigueroa-O'Farrill I'm afraid it's a bug in TeX Gyre Pagella, then: they should provide U+23AF

comment Expanding macros within \csname
@user66554 I added a different approach with your \print macro.

comment Expanding macros within \csname
@user66554 You have better ask a new question, stating precisely your aim, with a sensible minimal example.

comment Expanding macros within \csname
See my answer to What exactly do \csname and \endcsname do?, in particular the passage “It's possible to give many other interesting uses of this trick. But one should always keep in mind that TeX does complete expansion of what it finds in that context and that only characters must remain.”

comment Wick Contractions aren't displaying properly
Never use eqnarray; in this case the align* environment is what you want.

comment Glyphs from font not displayed
The warning has nothing to do with the existence of glyphs in a font.

comment Broken Arrow in Lucida Bright Font
@JoséFigueroa-O'Farrill Unfortunately, none of the TeX Gyre math fonts has the glyph; just don't redefine \relbar and you should be OK

comment Definition with roman counter value
If one wants to be on the safe side, it's better to use lowercase Roman numerals and \romannumeral (but after \csname, of course. \csname abc\romannumeral\value{#1}\endcsname would do, preserving expandability.

comment Definition with roman counter value
While \Roman is safe in ordinary conditions, it may give wrong results (aka puzzling errors) when certain babel languages are loaded.

comment how to compile without producing output
@JPi Producing the .aux file requires typesetting the document anyway: how can the page numbers be found, otherwise?

comment How to get access to this special character?
Try \XeTeXglyph191\relax or \XeTeXglyph"191\relax (the latter uses hexadecimal.
