More than 200 participants at TUG'20! Yeah!

I guess I am not enough of a mathematician  to understand the joke :(

Raaja replying to marmot

that would be awesome :D

marmot replying to BambOo

Too bad, 1137 is not a prime number.

BambOo

@@@ question 1137

BambOo replying to marmot

Just created a new question  here

marmot replying to BambOo

Yes, I know a distinguished scientist who was seriously considering to ask for a personal injury compensation for what they have done to their figures.

marmot replying to BambOo

I think it would be more advantageous to have a separate question on this (so that others who follow the chat do not have to get overwhelmed by some technical details, of course I cannot promise that I will be able to find the correct answwer.)

BambOo replying to marmot

Regarding journal publications, I always have trouble with images. Even though I provide `pgfplots/tikz` vector graphics they always end up being rasterized

BambOo replying to marmot

@marmot Thanks for the tip ! I tried your proposal, but it does not seem to take the mantissa sep into account. If I change `\cdot` with `\times` the separator is wrong.

marmot

Another journal destroyed my equations... good that I caught it. (This happens when they try to intelligently replace a LaTeX macro. So in the future even more editor shortcuts, less macros, and definitely no utf-8.)

Marmot bonsoir, https://www.geogebra.org/m/ygdfg9b7  question to follow on this one :)

marmot replying to Symbol 1

I am just a marmot, not a psychologist, so I do not know.

Why would anyone purposely provide misleading information LMAO

marmot replying to Symbol 1

As I said, this is a lengthy discussion. There are always questions which one cannot answer, and no one forces others to answer questions. If someone posts a code fragment that one cannot make sense of, one is free to ignore it. To be clear, I also think questions should have an MWE. However, I do not think that one should enforce policies that prevent one from answering them if one knows how to answer them. If one is to discuss policies, then there are IMHO much more urgent issues such as plagiarism or purposely providing misleading information because these, unlike answers to badly phrased questions, hurt the community.

Symbol 1

I agree the no-one-is-above part. That said, there are good reasons to insist, say, the MWE policy---to make questions more available to potential answers. There was a time when I knew nothing about what macros coming from which packages, but I was willing to spend a whole day looking at `\tracingmacros`. Without an MWE I have no starting point.

marmot replying to Symbol 1

That's a lengthy discussion, but I do not think it makes sense to tag questions as "do it for me". All questions ask the answerer to do something for them, namely answer the question. This tag has has traditionally abused to put certain users above others, which is why I do not like it.

marmot

@BambOo BTW, to notify users here you need to either reply to one of their messages, or to click on their icons. AFAIK just using `@<user name>` does not work, at least I did not get notified (but my browser seems not to be optimal, I very often need to press `shift+refresh` to see what's going on.

marmot replying to BambOo

I think it is more a problem of the manual, e.g.   
```  
\addplot[nodes near coords={\pgfmathprintnumber[sci,sci	generic/exponent={10^{#1}},sci	generic/mantissa sep=\cdot]\pgfplotspointmeta},domain=0:1,samples=5] {x};  
```  
works as expected. I would not have expected that `sci	generic` can be both a directory and a code at the same time, and while I do not really know why this seems to work in the pure Ti*k*Z setting, I do not really think one should introduce such a usage.

Symbol 1

It'll take a while for general public to realize that marmot answers more bad (do this for me) questions than anyone else could have.

Jack Douglas replying to BambOo

If you'd like to migrate it here, this can easily be arranged, and I'd be very glad to help.

BambOo

Hello marmot. Asked a question about pgfplots on tex.se and no one answered in the following 5 minutes ... Knew something was odd :)

marmot

For some reason the GitHub ghost looks very much like a marmot ghost.

I decided to do some anchor hacks     

		\makeatletter
		\def\tikz@install@auto@anchor@tip{%
			\def\tikz@do@auto@anchor{%
				\pgfmathsetmacro\tikz@anchor{atan2(-\pgf@y,-\pgf@x)}%
			}
		}
		\makeatother
		$$\tdplotsetmaincoords{60}{120}\tikz[tdplot_main_coords]{
			\draw[line width=.6,shorten >=1,nodes={pos=1,auto=tip}](0,0,0)
				edgenode{$R[1]$}(4,0,0)edgenode{$R[1]$}(0,4,0)edgenode{$R[3]$}(0,0,4);
			\tikzset{line width=2,every edge/.append style=-{>[line width=1]}}
			\begin{scope}[canvas is xy plane at z=0]
				\pgflowlevelsynccm\draw(0,0)edge(4,0)edge(0,4);
			\end{scope}
			\begin{scope}[canvas is zx plane at y=0]
				\pgflowlevelsynccm\draw(0,0)edge(4,0)edge(0,4);
			\end{scope}
			\begin{scope}[canvas is yz plane at x=0]
				\pgflowlevelsynccm\draw(0,0)edge(4,0)edge(0,4);
			\end{scope}
		}$$

That was inspired by `pos = 1.2` in the doc.

marmot replying to Symbol 1

Yes, this one works. (I am never sure if it safe to use negative dimensions but it seems to work.)

Symbol 1

Perfect

`180` passes my eye-compiler! I was thinking about `(a)!-1em!(b)`

marmot

```  
\documentclass[tikz,border=3mm]{standalone}
\usetikzlibrary{calc}
\begin{document}
\begin{tikzpicture}
\draw (0,0) coordinate (a)-- (3,0) coordinate (b) ($(b)!1em!180:(a)$) node{pft};
\end{tikzpicture}
\end{document}  
```

marmot replying to Symbol 1

Yes, with `calc` it is easy (but not in the way one may try first).

Symbol 1

(Maybe this is trivial using `calc`)

Symbol 1

I have another though. How can I place R[1], R[2], R[3] at `pos = 1 + 1em` instead of `pos = 1.2`

marmot replying to Symbol 1

With `tikz-cd` you can make glyphs arrow heads. So just make an arrow head that reads "This is a 3d arrow". ;-)

Symbol 1

I am :) with `canvas is xy plane at z = 0` etc.

marmot replying to Symbol 1

You can use `\pgflowlevelsynccm` to project the arrows on some planes.

Symbol 1

The cone one is not compatible with other arrows in my document =P

marmot replying to Symbol 1

I thought you were the author of the 3d arrow in pgf?

Symbol 1

I'm trying to make the arrow more 3D. But it's hard.

marmot replying to Symbol 1

The only thing that makes me sad is that someone (probably involuntarily) killed the `bbox` library. The updated version works fine, and would have been a nice addition to the pgf system.

Symbol 1

Sad that someone opened that box

marmot replying to Symbol 1

Luckily this has come to an end. (The name Schrödinger's cat was chosen to say that the cat could be gone at any point.)

Symbol 1

I should have guessed it. You were solving problems that no one bothers to touch.

marmot replying to Symbol 1

是。

Has the Cat always been you?!?!
