Hi all. Not a TeX question, but perhaps someone can help. When including key words (in amsart) in a paper, what factors are there to consider? How much should one talk about a topic in order for that topic to be a key word?

@TheSubstitute The keywords should summarise important concepts in the paper, I think. Ask yourself whether the keyword reflects an important aspect of the paper.

But you could ask on Academia SX, or check if there is such a question there already. Assuming this is an academic question (and it sounds like it is) it should be on-topic there.

thanks

I see you've asked one question on Academia already, so you at least know it exists.

And if you are not sure of on-topicness, one could ask on Academia Chat, of course.

Incidentally, you might be English (just a guess). But in any case, I think you're right that pure math career paths aren't great. Person with a pure math background here. You don't have to be doing spectacularly to make it, but you do have to be doing pretty well.

@FaheemMitha It seems you have to be doing well with a little bit of luck here and there. I am early in a PhD program. I am currently considering probability. I want to enjoy math as much as possible while remaining as marketable as possible.

How can I make for example the following, I haven't find it in the examples of these packages?

Have decided to work through unanswered questions from highest-voted downward: there are some very good ones at the top of the list :-)

I'm looking over old highly-voted unanswered questions. For this one, is there much to say beyond 'it's a binary thing'?

@DavidCarlisle I see you are trying to find us more work!

@DavidCarlisle There are no hats for 'make HarfBuzz work with LuaLaTeX' ;-)

@JosephWright there should be definitely hat for "make HarfBuzz work with LuaLaTeX on Windows" :-)

@michal.h21 :-)

@JosephWright you have already admitted to opting out of hats, so that is no excuse

@JosephWright and another one for "include it in TeX Live and in luaotfload" :D

@Joseph: since Lua is a Brazilian creation, you should definitely find a Brazilian and blame him. Oh wait.

@PauloCereda nice hat. It's a secret one? :-)

@PauloCereda ;-)

@RomainPicot ooh the master plan worked! :)

@DavidCarlisle ^^

@PauloCereda This is all your fault

@JosephWright You are mean. <3

@RomainPicot ^^

Coin coin! :)

@PauloCereda luatex 0.85 incompatibility is your fault

@DavidCarlisle Oh no!

@PauloCereda I must say that I've seen this comment :-)

@PauloCereda Quack ! :)

@PauloCereda In other news, I have Monty Python and the Holy Grail coming on BlueRay for the party I'm hosting tomorrow (this was something of a surprise: a friend decided it would be fun and invited several people before I got a chance to have a say!)

@PauloCereda I know it's true as Joseph said so

@DavidCarlisle I think Hans might be involved somewhere ...

@DavidCarlisle I am looking forward into the moment when I update Luatex to 0.85 and find that all my Lua packages fail :D

@JosephWright ooh awesome! It will be a great party!

@JosephWright without Paulo and his friends making Lua, Hans would have used python or something and everything would have been simpler, or something...

@PauloCereda I do hope so

@JosephWright Are questions like this one about PDF viewer issues supposed to be closed? There was a similar one closed as well, time ago (see the comments). But I didn't find anything specific in the Help Center or Meta about these questions.

@DavidCarlisle JF would have liked that, and several other people who complain about the choice of Lua (which is entirely reasonable, but why let that stand in the way of criticism)

@DavidCarlisle I will have to poke the gentlemen at PUC-Rio. :)

@Alenanno Borderline: we tend to help if we can as often something can be done in terms of the PDF processing

@JosephWright So what is your approach on this one?

Guys, I think I am going too far: I am working with macro expansions... for everything.

Applying, eg, macros in a stream of images...

@PauloCereda how far are you from Rio, exactly?

@DavidCarlisle Google tells me it's 624 km. :)

@PauloCereda quite a long way for a reindeer.

@DavidCarlisle And a duck. :)

@PauloCereda Or a bee

@RomainPicot buzz buzz!

:)

@PauloCereda By the way are you working on "vote early, vote often" hat?

@RomainPicot I have no idea. :)

@PauloCereda 250 votes in 7 days it's easy for the leader of the voting squad no? :p

@RomainPicot Yay!

@PauloCereda ^^

I got the easiest hat: ”hit the reputation cap on three different days”

@egreg I think the search one might be easier

@cfr: the hwyaden is sick again. :) I got the flu.

@PauloCereda you should live somewhere with better weather!

@DavidCarlisle Some foggy place? :)

@PauloCereda Wales?

@DavidCarlisle I wanna visit Cardiff! :)

@PauloCereda You'd love it on Snowdon: google.co.uk/…

@DavidCarlisle ooh it's cold!

@PauloCereda yes but usually you are so busy hanging on to something to avoid being blown over, that you don't notice the cold.

@DavidCarlisle ooh

@Alenanno: how you like my new duck?

@PauloCereda Mmmh cool, but the reindeer lol :D

@Alenanno there's a new one. :)

Is anyone here going to watch the new Star Wars movie?

@egreg: The martini in your avatar makes you look like a secret agent with permissiom to expand macros. :)

@PauloCereda My name is Egreg, Square Egreg.

@yo' You just did the right thing. ;-)

@egreg guess what the outcome was:

@DavidCarlisle :P

@PauloCereda Me!

@PauloCereda do you know if it's understandable if you only saw the first two (parts 3 and 4, I guess) or if you have to watch all the series to catch up?

@egreg :)

@Alenanno Yay!

@DavidCarlisle I suspect the first movies are sufficient. :)

Because AFAIK the movie takes from Vader's death.

@PauloCereda Did he die? ;-)

@egreg ooh that's a good question!

Let's wait until @Alenanno watches it!

@egreg Actually, I ruined @DavidCarlisle's experience, since Vader only dies in the last movie (part 6). :)

May I ask a question about typesetting a mathematical line?

@PauloCereda Well done!

@Khallil Yes!

@PauloCereda a mere thing like death didn't stop obi wan whathisname carrying on.

I wanna typeset this but I'm unsure on how to get the layout correct. I can easily type all the symbols e.g. \mathbb{R}^{n}, \mathbf{v}, \in etc. but the layout is puzzling me. I've tried an array but it looks pretty bad. Any ideas? :-)

@DavidCarlisle ooh

Also, may I ask how to write \in vertically?

@Khallil probably \rotatebox{90}{$\in$} although you may have to adjust the spacing a bit

@PauloCereda Wait, you've seen it already?

Thanks, @DavidCarlisle :-)

Any ideas for the vector field thing?

@Alenanno I wrote it. :)

Nah just kidding, I will watch it eventually. :)

I feel it may entail a commutative diagram of sorts?

@PauloCereda Ah ok. I was already going to avoid this room for spoilers lol

@Alenanno Snoke is the older brother of Luke Skywalker. You are welcome.

@PauloCereda :O

D:

@Khallil possibly an array with c@{}c@{}c@{}c@{}c@{} so there is no intercol space so V&{}:{}&R^n&{}\rightarrow{}&R^n for the first line will give you normal spacing for the arrow, then just align in the following rows

@Alenanno Just kidding, I am teasing with you. :) I have no idea of the movie plot. :)

But it would be ironically delicious if this happens to be true. :)

@PauloCereda Dude, if he turns out to be that for real though

@PauloCereda Exactly

@Alenanno Ducks are wacky creatures. :)

@PauloCereda :D eheh gotta go now, see you later!

@Alenanno See ya!

I managed to get this, @DavidCarlisle.

Do you know how I could add a bit of spacing between the \ins and the \mathbb{R}^ns and possible move the \ins slightly to the left?

@Khallil you can use \\[5pt] or whatever you need for vertical spacing, th eins are centred under R^n you probably want to centre under R so you could do \rotatebox{..}\phantom{^n} or just add some hspace{..} "by eye"

May I ask where to use \\[5pt], @DavidCarlisle?

@Khallil where you have \\ to end a row you can use [some vertical length] to add space

Oh awesome! I've not used LaTeX much for formatting so the \phantom code is a bit obscure to me right now. Can I ask what it does, @DavidCarlisle? Yep, I do indeed desire the \ins to be centred under the R.

@Khallil \phantom makes an empty box the size of whatever you give so it just takes up the space of a superscript n without actually showing one

That is amazing! LaTeX is so versatile. :-)

Another quick question, @DavidCarlisle! If I've managed to define a shaded background, is there a way that I can limit the width to just the text I've written down?

(I want to limit the above to simply wrap around the array we defined earlier.)

@Khallil \colorbox{yourcolor}{$\begin{array.....

Ah thank you. How then would one extend the boundary of the shaded area, @DavidCarlisle?

@Khallil {\setlength\fboxsep{1cm}\colorbox......}`

Sorry for the late reply, @DavidCarlisle! My net shut off for a while. Thank you!

May I ask which packages are necessary to render \mathcal{L}?

I've been trying to search it up on Google but alas, it is to no avail :-(

Anyone use LaTeX for US NIH biosketches? It looks like the CTAN NIH package is way out of date.

@Khallil None.

Really? On my file, I've been trying to render it but I keep getting a normal capital Latin L as opposed to $\mathcal{L}$, @TorbjørnT.

@Khallil Well \documentclass{article}\begin{document}$\mathcal{L}$\end{document} gives the expected output here, so there might be something else in your document that messes things up.

Ah it seems so.

I'm trying to tag an equation with the $\mathcal{L}$ as a label. That may be the issue.

Ah it appears to be working now. Awfully strange. I must have fixed something mismatched by accident.

@Khallil no package needed

Yep, I noticed! May I ask how one can lower the position of the footnotes/page number down the page, @DavidCarlisle?

@Khallil do you mean make the text block bigger (just increase \textheight) or move the page number down within the footer, so leaving a bigger gap above (various ways, fancyhdr package probably easiest)

I mean shifting the entire footer and page number further down the page to increase the vertical height in which I can input text, @DavidCarlisle.

@Khallil Ok then as I say you can just \addtolength\textheight{4\baselineskip} to make the page 4 lines longer (best to work in \baselineskip rather than length units) or use geometry package where you can specify it lots of ways eg specify a page size and bottom margin and it does the sums for you

New free game downloaded on XONE.

@PauloCereda vim?

@PauloCereda XONE?

@PauloCereda Ah, Xbox

@PauloCereda Santa Duck? ;-)

@JosephWright In general, I go with X360 for the 360 and XONE for the... well, One. :)

@ChristianHupfer Quack quack quack!

@DavidCarlisle Vim is not a game, it's a serious business. :)

Hey guys, I wrote a syntactic macro for fish!

@PauloCereda even for a duck that's a very silly comment

@PauloCereda Vim is violating the Geneva Convention for Human Rights :-P

I used \vspace{-x.0cm} in my title to shift my text upwards. Would there be an equivalent for the footer by any chance, @DavidCarlisle?

What does 'got me squared away' mean?

@Khallil well that would be wrong I guess. vspace adds space at that point so should rarely be needed and only affects that page but it sounded like you wanted to affect the page dimensions. But too many questions for chat, use the question site, with an example:-)

@DavidCarlisle last line of buffer. :) ^^^

@PauloCereda obviously a wise editor: you should use it more often

@ChristianHupfer Arranged or properly taken care of.

@Khallil Ah, thanks. Is this some slang?

@DavidCarlisle vvv

@JosephWright: ^^ :)

I think it's just a fairly old turn of phrase, @ChristianHupfer.

Output of :Ni!

@Khallil Never saw/heard it before. Thanks!

:-)

@ChristianHupfer -- i can confirm that it's a very old expression; i've heard it since childhood. being curious, though, i explored further, and found at beta.merriam-webster.com/dictionary/square%20away that its first known use was 1838, and it referred to setting sails on a square-rigged ship in order to sail directly downwind. in modern use, its principal meaning is to put things in order. (my father was a navy man, so it's not surprising that i heard the term early in life.)

@ChristianHupfer I'm still squared. ;-)

@egreg: Quadratisch. Praktisch. Gut.

Have people read meta.stackexchange.com/questions/271080/…

@JosephWright not yet

@yo' DO

@JosephWright I did. It got a -1 from me. It is undiscussed, short-notice and absolute. Three things that shouldn't happen in a community-discussed environment.

@yo' Yup

@yo' Sounds about right to me

@yo' I suspect we are OK as most of the code posted here is for individual documents (not distributed, i.e. end user theses, etc.)

@JosephWright I don't say that licenses matter to me a lot, nor that MIT license is bad, but am I really supposed to learn what it is about in 2 weeks?

@yo' Quite

@JosephWright obviously.

@yo' Making a change over the Christmas/New Year period is also a bit questionable, at least without a decent amount of notice

@JosephWright I understand the over-the-new-year argument. I suggest we make it 2016/17 though.

@yo' Yes I can see it as a useful marker, but not starting the discussion on the 16th of December

@JosephWright right.

@JosephWright do you think it affects the standing of our meta question where most of us have answers revoking the CC licence on code snippets

@JosephWright yes Ok i suppose so, so I guess it doesn't affect me then as I'm already saying do what you want with any code I post here

@DavidCarlisle Seems to be missing?

@JosephWright Here we go again.

@JosephWright We are indeed ok. :)

@JosephWright what seems to be missing?
