Has anyone else noticed that the quite attractive headers for our site have been mashed into corporate nonentities? The Tengwar example on the main site is almost unreadable, and it's very hard to make out any bits of typeset math, which was the original rationale for TeX's existence, And I miss the cheery red brackets on the meta site; they're now gray and institutional. See the "Featured on Meta" item. "Our Design Vision", for details. Vision? It's more like a nightmare.

@barbarabeeton The took all nice things away in the great un-design of 2018

^^^ Luckily there are user scripts :)

@PauloCereda QUACK

Paulo Cereda

@JosephWright ooh a duck

@JosephWright quack <3

@mickep @egreg meanwhile, on Twitter: Q. How do you know the Swedish band ABBA doesn't drive to work? A. If they commuted, they would be A²B².

mickep

@PauloCereda Oh, haha! (Googling ABBA, they are called a "supergroup", I don't know if those are abelian or not.)

Rmano

09:15

@PauloCereda Well, they really were AᗺBA, didn't they? ;-)

Paulo Cereda

@Rmano mamma mia, here we go again :)

Paulo Cereda

@barbarabeeton One for you: a rough translation would be "a pigeon who does not like bad spelling and decided to take action on the matter". It should be Teatro Góngora. :) (@Rmano)

samcarter

@PauloCereda The pigeon should turn around, currently it looks more like an accent grave :)

Paulo Cereda

@samcarter pigeons are not exactly good at diacritics :)

samcarter

@PauloCereda :)

Spent the morning making a flow chart in TikZ: for once for my day job :)

I am quite pleased with it

Ulrike Fischer

13:49

@JosephWright ;-) Perhaps the linear should be a bit more prominent. Without knowing what this about it is not at first glance obvious that it is the start point.

Joseph Wright

@UlrikeFischer Version I modelled it on had 'molecule' there, and 'linear' in the middle - I might try adding some greysclale for emphasis

@StefanKottwitz will be slightly disappointed that I didn't use the methods from his book went with an Overleaf tutorial as a starting point instead

@UlrikeFischer I'll make that text bold

barbara beeton

14:09

@samcarter -- Clearly, I haven't been paying attention. Fie!

@PauloCereda -- Here in Providence, we have a pigeon defense -- a resident peregrine.

Joseph Wright

@UlrikeFischer Hopefully my students will know what this is about ;) (Assignment of point groups)

samcarter

@barbarabeeton The site is so soulless since the great un-design. I'm very grateful for the existence of user scripts. Thanks to them, I recently got the pen nibs voting arrows back tex.meta.stackexchange.com/questions/10080/…

Overleaf has caught up and provides TeX Live 2023 now

Paulo Cereda

@yo' woooo

mickep

@yo' Ohh, yay

chsk

Good afternoon!

Paulo Cereda

@mickep 'ello!

mickep

@PauloCereda Oh, hi

Is anyone reading/has anyone read Stefan Kottwitz's LaTeX Graphics with TikZ by any chance?

I'm having no luck with his let's use style 2 args to create node styles for network diagrams example on pp. 72f.

Joseph Wright

@chsk I've read all of it :)

@chsk What exactly does your input look like?

@yo' Spaces missing in ElegantLaTeX packages removed from TeX Live (I think, at least)

chsk

15:39

@JosephWright cool. :) Here's what I have:

```
\documentclass[varwidth,border=10pt]{standalone}
\usepackage{tikz}
\usepackage{graphicx}
\usetikzlibrary{positioning}
\tikzset{
image/.style 2 args = { path picture = { \node at (path picture bounding box.center) { \includegraphics[width=#1cm] {#2}};}},
router/.style = { image = {2}{router.pdf} },
switch/.style = { image = {3}{switch.pdf} }
}
\begin{document}
\begin{tikzpicture}
\node[router] (r) {};
\node[switch, right = 4 cm of r] (s) {};
\end{tikzpicture}

The referenced PDF files are converted from the Cisco EPS collection that Stefan mentions earlier in the book.

It looks like the lack of a label on the nodes is causing the pictures to not appear as intended, but I'm not sure how to remedy that, or what exactly Stefan had in mind there.

@yo' you still can use ucs (not that I recommend it), but you must do it explicitly and not implicitly through utf8x. And naturally you could add the math definitions also when using utf8 (perhaps we should do it by default ... @DavidCarlisle? )

\documentclass{article}
\usepackage{ucs}
\usepackage[utf8x]{inputenc}
\begin{document}
∃x such that ∀y ≠ x $∃x$ such that $∀y ≠ x$
\end{document}

yo'

16:26

@UlrikeFischer I am happy to say you cannot, even if there is a way to do it, as I think you simply shouldn't need to. As for math symbols availability in text mode via unicode, I don't see a point in doing that?

(but I'll raise the ucs thing and see what we agree on)

Ulrike Fischer

@yo' well some people like to do it, and we actually discussed at some point to take over the math definitions from ucs, but it then got a bit forgotten. Did you contact the caption author about the \label error?

Joseph Wright

@UlrikeFischer Indeed

Ulrike Fischer

16:48

@yo' and regarding the remark about caption: The best is to load the nameref package, then the problem disappears:

\documentclass{article}
\usepackage{nameref}
\usepackage{caption}
\begin{document}
\begin{figure}
\caption{\label{fig:compare-two}Comparison of two approaches}
\end{figure}
\end{document}

Joseph Wright

@UlrikeFischer firstaid?

Ulrike Fischer

17:18

@JosephWright I'm not sure. The author knows the problem and also the source (the package does \def\@currentlabelname{#1} without sanitizing the argument.)

@UlrikeFischer True

@JosephWright something is broken in l3build after the update. When I run in base l3build check tlb-ealloc-002 it stopps, so it looks as if the nonstopmode is missing.
