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 Remove colon from title bar in tcolorbox theorem without a title
Neither can I; with the current version the colon is not printed if the title is empty. I suggest you to say \tcbmaketheorem{task}{\strut Task}{fonttitle=\bfseries}{task}{tk} so the title bar will have a predetermined height (you see that the heights are different in your example, due to the “p” with a descender in the left box).

Of course I like best the second solution. ;-)

comment Lines overrun margins
In addition to @TorbjørnT.'s remarks, note that in typewriter type the interword space has no flexibility; the lines with math can be adjusted, but not the line with “of our” that has no math in it.

comment Writing to and extracting from aux not working?
It doesn't work when calc is loaded. I'd go with \global\templength=150pt\relax (none of these tokens is expandable).

comment Possible bug with \implies and \Longrightarrow — there's a dot in the middle of it
Did you try with \documentclass[12pt]{article}?

comment There's a bump in the implies glyph
I don't think it's the same problem or, at least, the other question was answered without knowing the real problem which appears when 12pt font size is used. The issue is in the fact that the two glyphs are taken from different fonts: the equals sign from lmr12, the arrow from lmsy10 at 12pt.

comment There's a bump in the implies glyph
It's an evident bug of the Latin Modern fonts; it's not the same in the OpenType version. The equals sign is used for lengthening the double arrow, but in the 12pt font they don't agree; they do at 10pt (and 11pt, where the scaled 10pt font is used).

comment Disabling “glue” and other vertical space adjustment?
Some of your settings are not obeyed, for instance \baselineskip will be the same as the default (and indeed 11pt with a 12pt font size would produce a very crowded and unreadable output). You forget that center adds \topsep glue.

comment make ``quote'' output as “quote„
Of course this breaks math $f'(x)$, which is one of the drawbacks.

comment Problems with \textsc for single glyph
@PhilG Actually this is a simplistic solution: there are many kerning pairs involving æ and I didn't approach the problem. Go to EB Garamond. ;-)

comment Warning: \oval, \circle, or \line size unavailable
The warning happens when \fancyoval calls \@getcirc and in the computations the resulting number is bigger than 10. Since fancybox directly calls \@getcirc, it doesn't profit of pict2e. Using \oval avoids the warning.

comment Consistent way to define document title, subtitle, author, affiliation, abstract etc
@krlmlr That's a tough decision. I'd go with the LaTeX3 functions.

comment Consistent way to define document title, subtitle, author, affiliation, abstract etc
@krlmlr \hypersetup{pdftitle=Title, pdfauthor=Someone} works also after \begin{document} (just checked). My preference is towards having the data after \begin{document} so they won't be hidden in the preamble; anyway, just check in the articledata environment where it's placed and in case issue \AtBeginDocument{\myclass@maketitle} where the command does all the related work.

comment tlmgr cannot setup TLPDB
If your TeX Live has been installed with apt-get you can't install tlmgr over it. And, if you do in some way, you can't rely on it to work.
