TeX, LaTeX and Friends

12:03 AM

@samcarter_left_tex.se --It's day 2 that is the real beast; starts around 3 a.m. local time, and doesn't give up until 2 a.m. the next morning. A few talks I really wanted to watch are during serious sleep time, so I just hope the writeups are good.

@manooooh -- The leaders of the tutorial have led a tutorial along with the in-person TUG meeting for many years. (I've never attended, but they have always been appreciated. It's rather a thankless task, really.)

I think that the core question in Is the size of the black hole illustration in this PDF really “exact”? If so, how could I determine its size in centimeters? is on-topic.

I've removed the superfluous material and bumped it into the review queue. I'd really like to know the answer!

If there's a different SE site where it would be better to post than here, please let me know!

@uhoh your question is about the PDF standard and printing, not about LaTeX. On how you could measure it: some viewers (e.g., Foxit) have a measurement tool, a quick search on the internet might help. Still, this is nothing TeX related.

@barbarabeeton I also will have to fall back to the recorded videos for the talks of Ross Moore and following. As an isolated event they would be doable, but not if there are other sessions a couple of hours before and after :) Scheduling with all these time zones is really not easy. Other online conferences now often use only half a day (late evening in Asia, afternoon in Europe and morning in US), but of course this doubles the number of days and events get very long then.

@samcarter_left_tex.se I will have to watch everything as a recorded video :(

@Skillmonlikestopanswers.xyz :(

@uhoh I don't have time right now to search, but I think there was a video discussing the scaling issue of the image. Either from youtube.com/channel/UCYNbYGl89UUowy8oXkipC-Q or youtube.com/user/sixtysymbols

(thinking about it, I think it was on 60 symbols)

@uhoh I think you can simplify the problem. If you download the source from arxiv, you'll find the image Fig9cmBH.pdf and it is included as \includegraphics[height=9.35cm]{Fig9cmBH}. So assuming the claim that this is 1:1 is correct, you'll only have to scale the image to have a height of 9.35cm (hold a ruler to your screen until this is true)

@DavidCarlisle Slide from a conference about open source software I'm currently at ^^^^

(maybe they just say this because we don't have a @UlrikeFischer)

@samcarter_left_tex.se you don't know whether the file contains a white border...

samcarter_left_tex.se

@Skillmonlikestopanswers.xyz It does, I'll have to trust the authors that they did take this into account

uhoh

@samcarter_left_tex.se okay I can download the source from here and I have only one file named 1909.11090 no additional figures are downloaded. When I view that as text and I've found that bit here and again here but I'm not sure how to display the exact thing that I need to scale to 9.35 cm. There doesn't seem to be a separate image to work with, at least not as a separately downloaded file

Since it's simply a filled circle it's probably just generated as some primitive shape. I'd thought that this was done using LaTeX but apparently not.

@Skillmonlikestopanswers.xyz okay I understand now that it's not LaTeX now, thanks!

samcarter_left_tex.se

@uhoh Rename the file 1909.11090 to 1909.11090.tar.gz and uncompress to get the image

Joseph Wright

@samcarter_left_tex.se Or just unzip (I use 7-zip so just right-clicked and opened)

samcarter_left_tex.se

@JosephWright But then I don't have my zip program in the "open with..." list and have to search it in the whole list of programs :)

Joseph Wright

@samcarter_left_tex.se :)

@samcarter_left_tex.se Fun reading the source: I wonder what will happen when people using {\bf 1. ...} for sections are asked about tagged PDFs ;) (@UlrikeFischer)

Also

\def\beq{\begin{equation}\begin{aligned}}
\def\eeq{\end{aligned}\end{equation}}

:(

@DavidCarlisle, @egreg ^^^

yo'

@JosephWright they're just missing \! that should surround {aligned}

@JosephWright In the daily email with the new papers on arxiv the code for titles and abstract are shown as plain text. Every second paper uses such stuff. Reading this mail can be quite painful

Joseph Wright

@samcarter_left_tex.se I get that; it's a shame, and it is actually an issue: as I'm in an area using Word submissions, I've no idea what happens about clean-up of TeX sources for published versions

uhoh

@samcarter_left_tex.se aha! There it is :-) The black circle is about 0.960 the size of the white frame, that multitplied by 9.35 cm gives 8.98 (essentially 9.0) cm. Okay This is exactly what I needed, thank you for your patience and help!

samcarter_left_tex.se

@uhoh You're welcome!

uhoh

@samcarter_left_tex.se however now the rest of my day's productivity is shot because I'm going to be watching sixty-symbols videos, I've got a lot of catching up to do :-)

I didn't know about Dr. Becky so I'll save those for the weekend.

samcarter_left_tex.se

@uhoh :) I'm sorry! So should we prepare for a wave of interesting questions on astro.se?

@uhoh Dr Becky is really great. I met her at a conference some time ago and her talk was really standing out. Seems thinking about science communication is really worth the effort.

Ulrike Fischer

9:34 AM

@JosephWright well they will get normal "paragraph" text and no headings - that what word user get if they create their section by making them larger and bold ;-)

Joseph Wright

@samcarter_left_tex.se I didn't know astronomy was your day-job

samcarter_left_tex.se

@JosephWright mixture of astronomy and particle physics

Joseph Wright

@UlrikeFischer Well yes, but it's a shame when every basic LaTeX intro covers \section

@samcarter_left_tex.se Ah, right

@samcarter_left_tex.se Big instrument stuff?

uhoh

@samcarter_left_tex.se I've posted "Dr. Becky to the rescue! How to spot Comet NEOWISE, plus the largest 3D map of the Universe | Night Sky News July 20" under three questions already. This reminds me that I need to improve this answer: astronomy.stackexchange.com/a/36901/7982

samcarter_left_tex.se

@JosephWright One of the instruments I work for has "Cubic Kilometre" in the name, so yes :)

Joseph Wright

9:38 AM

@samcarter_left_tex.se km3net.org?

Ulrike Fischer

@JosephWright yes but neither does the intro covers how to get say a normal sized section, nor does offer LaTeX easy tools to adjust the fonts here. You need a better class like memoir or the koma classes for this. The tutorial examples yesterday had a \Large in the code -- probably to make the pdf better readable, but this too could done with the koma classes better.

@JosephWright yipp

Joseph Wright

@UlrikeFischer It's a paper using REVTeX, so (as I say a lot to authors using achemso): 'do not worry about formatting, that's the job of the editorial office'

@UlrikeFischer I hope to see some of the video today

@UlrikeFischer As I understand it, arXiv is about manuscripts, not finalised papers, so really they don't even need to be two-column (I'd actually say they must not be, and should be double-spaced, but then I'm used to classical manuscript submission)

Ulrike Fischer

@JosephWright oh revtex ;-) Everytime I look at the code I hope I don't have to debug it.

Joseph Wright

@UlrikeFischer Well it's physics, so of course its REVTeX

@samcarter_left_tex.se Ah, cool: sounds fun (and expensive)
