comment Add nodes with pgfplots
If you don't plot anything the default axis limits won't change. Also you need \pgfplotsset{compat=1.12} to benefit from the coordinate system handling.

comment How to make a package using sagetex and sage-commands
@LaRiFaRi That's not our call. Somebody might need this later. It is a perfectly viable question. With proper explanation. The questions in the comments are secondary nature. But probably it will be closed because of your vote.

@LaRiFaRi That is hardly a reason to close a question.

comment Pascal's Triangle + Fibonacci Numbers
@HeikoOberdiek My bad. Too fast typing. Thanks for the correction.

You can remove the package with \ifnum\k=0\draw (\n\k.south west) -- (\x\y.north east);\fi

comment Setting a length with a key to a TikZ node
I read a lot of PGF code some time ago, that's how I remember it. And as I tried to show below its meaning is context dependent on \nullfont activation.

comment 3n arguments in a macro (n is an even number) for curves whose thicknesses increase or decrease
You can send in one argument of a long array and parse it internally to 3n parts.

comment Setting a length with a key to a TikZ node
Try this as the code of the key : \pgfutil@selectfont\settowidth\aetmplength{#1}\pgfkeysalso{text width=\the\aetmplength}

comment Setting a length with a key to a TikZ node
Sorry my mistaken presumption. I meant: \nullfont is the primitive, roughly speaking, that maps the font definition to zero. Hence in the code, your text input is expanded to zero width as text is mapped to nullfont. You can place things into a temporary box and measure its width instead. TikZ does that to ignore any dangling text commands etc. within the picture.

It is \nullfont inside the tikz picture.

comment How to Extract Elements?
You make a list via double braces \def\zz{{1,2,3,4}}. Then access the elements via first executing the caller \pgfmathparse{\zz[3]} and then using the result that is kept in the macro \pgfmathresult. Mathematica and other CAS are a different breed, you will quickly see that you need to change your view on TeX programming. Feature X in Y probably won't exist in TeX and you have to morph into a different type of programming. Macro expansion is completely different than typed languages.

comment tikz being mishandled by manuscriptcentral
Does it work if you remove the layered arguments? I think manuscript central fiddles with the background layer to put watermarks. Try putting an empty backbackground layer to the layer list. Maybe it would remove the clash.

comment Differences that implementation of `\node` and `\coordinate` have on display
Add draw option to the nodes and it will be a bit more obvious

comment Name tikz pic as if it was a node
pic is the mechanism to include a predefined drawing. It is not a referable object. Unless there is something defined in it, that is. Think of it as a container. And your example needs some corrections to be compiled e.g., \pic at (0,0) {myBlock};\pic (S) at (3,0) {myBlockNamed};\draw (S-m) -- ++(2,0); works. The first one you need to remove the at (0,0) from the definition

Instead you can \unhbox it without the internal hack.

comment Latex by using command lines in a terminal
About the windows oddness you need the switch /d to change both the drive and the directory. So you need cd /d D:\foo\bar

comment What is the meaning of \fussy, \sloppy, \emergencystretch, \tolerance, \hbadness?
I would then suggest made up words that TeX doesn't have a hyphenation for such as asdfdfsefasdfasefase... because they are not treated the same hence verb, math etc. is different than those made-up words

comment What is the meaning of \fussy, \sloppy, \emergencystretch, \tolerance, \hbadness?
This question is rather specific to math linebreaks. Hence the title is over general for the parameters you are asking for actually. The last two is covered here: whats-the-difference-between-tolerance-and-badness

comment Typeset pgfmath number in text mode
It is rather a shorthand without the bold part assume that you are already in math mode
