Wow. TUG Vol 36 no.2, Peter Karow, the examples at the last two pages look really good compared to the right columns.

@egreg Do we have a good duplicate for How can i have an unnumbered section? for the motivation question?

@Johannes_B Not that I can find

@egreg No question for the very simplest problems.

:-(

@egreg I love github :-) github.com/vinee109/TexStyles/blob/master/studyguide/…

@TorbjørnT.: thanks for helping with that question. :)

@clemens: another person for us to follow: github.com/cfr42 :)

In the following example, i don't see the line if the color is explicitely given as black. Can somebody confirm this?

\listfiles
\documentclass[xcolor={dvipsnames},table]{beamer}
\begin{document}
\begin{frame}
	\arrayrulecolor{black}% Commment to see cline
	\begin{tabular}{ccc}
		Wombat& Low      & High \\
		\cline{1-2}
		colortbl.sty &   2012/02/13 v1.0a &Color table columns (DPC)
	\end{tabular}
\end{frame}

\end{document}

@Johannes_B Yes. But just to be clear, the colour doesn't matter; anything in the \arrayrulecolor command makes the line disappear.

@Johannes_B see e.g. tex.stackexchange.com/a/159383/36296

@samcarter Sometimes on the site it seems like we've answered all the possible questions. :)

@AlanMunn We just have to find them :)

@samcarter Correct. The solution works well for cline :-) Thanks

@Johannes_B guess the title of section 10 of texdoc colortbl :-)

@DavidCarlisle I read that, but still. Who even implemented colored tables? Most of them are awful. ;-)

@Johannes_B I only wrote colortbl to avoid Sebastian and Michel describing an even more horrible hack in the graphics companion book:-)

@DavidCarlisle :-)

My newest answering technique: edit the question. :) tex.stackexchange.com/q/321590/2693

Had feijoada today. :)

@PauloCereda I officially started my holiday, today. :)

@egreg yay!

:D

Suppose Package X provides a modification to either Package A or Package B (which are mutually incompatible). Is it better to pass the package name as an explicit option to Package X (perhaps with some default) or rely on \@ifpackageloaded?

If you're sure a user will not load both A and B,…

@egreg Well I'm pretty sure of that.

@egreg Assume that's true, which is the better/safer/simpler route? It seems simpler the rely on \@ifpackageloaded rather than have options.

@AlanMunn I agree

@egreg One other question: if I want to explicitly say in the console output that the package patching has been done, is it better to use \PackageWarning or just use \typeout?

@AlanMunn Better \typeout; a warning will just worry users.

@egreg Yes, that's what I thought.

Do we have a good question that explains to the clueless the different between latex+dvips and pdflatex? The "what are the differences between the engines" questions are really too technical for a beginner.

@AlanMunn I suppose tex.stackexchange.com/questions/349/… might be a promising question, but I'm not sure if the answers are exactly what you're after.

@TorbjørnT. Thanks I hadn't found that one, and it's the closest one to what I was looking for. It's not terrible, but the accepted answer is a bit besides the point unfortunately.
