@samcarter_is_at_topanswers.xyz I was wondering how @DavidCarlisle showed up in that chat :)

@DavidCarlisle Still I think that's a strange name for something particularly used to space out displayed equations...
@DavidCarlisle Seems likely :)
@DavidCarlisle Also, that is in fact the German name for the letter J (Jot, I mean).
 
David Carlisle
David Carlisle
9:12 AM
@Skillmonlikestopanswers.xyz but that is swayed by not knowing the word in advance I guess. I always just read it as "adding a jot (unspecified small amount) of space to open up the equation.
@Skillmonlikestopanswers.xyz actually that is something that might be understood as a common english phrase unlike, say \quad which is a typesetting specific terminology that would be recognised as meaning a square but not as a space by normal people.

@DavidCarlisle I guess I just prefer speaking names. This reminds me of some code written by one of my professors which had great speaking names in it. E.g. the variable name R_matrix, obviously standing for a T matrix...
 
David Carlisle
David Carlisle
@Skillmonlikestopanswers.xyz speaking is what DEK would have in mind, the plain tex use is \openup 1\jot which corresponds to the natural language "open up the expression a jot" == " open them up a bit"
 
Skillmon likes topanswers.xyz
Skillmon likes topanswers.xyz
@DavidCarlisle yes, but deciding to space out displayed maths a bit more with \jot=5pt instead of something like \adddisplayedmathsspacing=5pt (not a great name either, I admit) doesn't seem more natural, imho.
@DavidCarlisle so it makes sense in the context it is used in his code, but not in the context a typical user would change it, which, imho, is the place where natural language should apply.
 
David Carlisle
David Carlisle
@Skillmonlikestopanswers.xyz typically it is never changed but it is used in-document to open up specific displays. changing the value of \jot is of course possible but somewhat rare I think.

Just wondering: Is is well known that the changebar and the float package does not like each other, in the sense that changebar has to be loaded last?
\documentclass{article}
\usepackage{changebar} % fails
\usepackage{float}
% \usepackage{changebar} % works
\begin{document}
test
\end{document}
 
samcarter_is_at_topanswers.xyz
samcarter_is_at_topanswers.xyz
@daleif changebar says in the documentation, that it needs to make changes to the definitions of the float package, so probably not a big surprise that it has to be loaded afterwards
 
Skillmon likes topanswers.xyz
Skillmon likes topanswers.xyz
@daleif changebar patches \end@float by doing \let\ltx@end@float\end@float\def\cb@end@float{<stuff>\ltx@end@float}\let\end@float\cb@end@float, so I guess it's obvious (once you read the sources)

@samcarter_is_at_topanswers.xyz -- I see that @DavidCarlisle has hopped in with an authoritative reference. What is lef out, however, is one (once?) common usage: "jot and tittle", which refer to the dot over an "i" and the crossbar on a "t" respectively. So "jot" is something very small.

how would I find a manual for tikzlibrary matrix?
as in what you get with \usetikzlibrary{matrix}
 
David Carlisle
David Carlisle
@Anush texdoc tikz then search for matrix
 
Anush
Anush
@DavidCarlisle oh it's not a separate library. Thanks
the code is too fancy for me even with the manual. I just want to write the columns names (which are 1, 2, 3)
 
Alan Munn
Alan Munn
@DavidCarlisle This is advice from someone who never reads documentation. There will be far too many matrix instances for this to be helpful. :)
 
Anush
Anush
 
Alan Munn
Alan Munn
@Anush In the TiikZ documentation there's a section containing all the libraries. So look in the contents for the matrix library.
 
David Carlisle
David Carlisle
3:11 PM
@AlanMunn OK I'll rephrase: open the tikz manual and read each page until you come to the matrix library section. Better?
 
Alan Munn
Alan Munn
@DavidCarlisle Much better.
 
Anush
Anush
@AlanMunn Thanks. The problem is the code I pasted above is doing something cleverer than the norm I think
a simpler question.. how can I make the + and - signs in the code I pasted above bold and red?
 
David Carlisle
David Carlisle
@AlanMunn although more seriously if you open the tikz manual and search for matrix the first hit is the table of contents referencing the matrix library
 
Alan Munn
Alan Munn
@DavidCarlisle Fair enough.
 
Anush
Anush
@DavidCarlisle It's "Anchoring a Matrix" in fact :)
 
David Carlisle
David Carlisle
3:14 PM
@AlanMunn Not that I had tested that first:-)
 
Alan Munn
Alan Munn
3:30 PM
@Anush You can add the following to your \path options (right after the nodes={...} line (add a comma after that line) 
column 2/.style={red,font=\bfseries},
column 3/.style={red,font=\bfseries},
column 4/.style={red,font=\bfseries}
 
Anush
Anush
@AlanMunn I don't think that made it bold
there seems to be something in unicode called a heavy plus sign
but that doesn't help me of course
 
Alan Munn
Alan Munn
@Anush That's because it's in math mode
 
David Carlisle
David Carlisle
@Anush bfseries would not affect math, if that is $+$ try \boldmath instead
 
Anush
Anush
\boldmath makes $h_1$ bold which I don't want but doesn't change +
or -
 
Alan Munn
Alan Munn
3:45 PM
@Anush Another alternative: load amsmath, wrap your \my@item in \text like this: (from the definition of \Uncoverlist): \only<\c@pgf@counta->{\text{\my@item}}
Then use:
 
Anush
Anush
@AlanMunn thanks
 
Alan Munn
Alan Munn
red,font=\bfseries,
column 1/.style={black,font=\normalfont}
And you'll need to replace the - in the array with a long hyphen – to match what the minus sign looks like
 
Anush
Anush
@AlanMunn does that work for you?
it doesn't make it bold for me
 
Alan Munn
Alan Munn
The bold and non bold + don't look much different. But it's definitely working because it you change \bfseries to \itshape it makes them all italics.
 
Anush
Anush
red,font=\bfseries,
column 1/.style={black,font=\normalfont},
column 2/.style={black,font=\normalfont},
column 3/.style={black,font=\normalfont}
 
David Carlisle
David Carlisle
3:50 PM
@AlanMunn ah so it's a text + not math one?
 
Anush
Anush
gives me
 
Alan Munn
Alan Munn
But the spacing isn't very pleasant for the minus in this case.
@Anush No, that's not what I suggested.
 
Anush
Anush
oh just column 1?
 
Alan Munn
Alan Munn
nodes={text height=1.6em,text depth=0.2ex,cond},
red,font=\bfseries,
column 1/.style={black,font=\normalfont}
@Anush ^^^ this way you only specify the odd column out, namely the first.
@DavidCarlisle Yes.
 
Anush
Anush
nodes={text height=1.6em,text depth=0.2ex,cond},
red,font=\bfseries,
column 1/.style={black,font=\normalfont}
gives me
 
Alan Munn
Alan Munn
3:52 PM
@DavidCarlisle I couldn't get \boldmath to do anything.
 
Anush
Anush
 
Alan Munn
Alan Munn
@DavidCarlisle Is \boldmath a switch or does it take an argument?
@Anush Did you change the definition of \Uncoverlist as I suggested?
 
Anush
Anush
argh.. no sorry
 
David Carlisle
David Carlisle
@AlanMunn switch (to be used out of math)
 
Alan Munn
Alan Munn
@DavidCarlisle Hmm, so it should have worked. But didn't seem to do much.
 
Anush
Anush
3:55 PM
@AlanMunn could you paste the new definition here please
 
David Carlisle
David Carlisle
@AlanMunn I came in late what font set is being used, does it have bold math? (oh I suppose it does as Anush showed bold h_1)
 
Alan Munn
Alan Munn
@Anush Actually @DavidCarlisle has identified the problem. The \boldmath version doesn't work because you don't have font with a bold math series.
So the simpler solution (with no change to the \Uncoverlist solution will work
nodes={text height=1.6em,text depth=0.2ex,cond},
red,font=\boldmath,
column 1/.style={black,font=\normalfont}
And load e.g. lmodern or a font that has a bold math series
 
Anush
Anush
that works! How did you get the shorter -?
you said "replace the - in the array with a long hyphen – " but how do you do that?
I like your short one in any case
@AlanMunn thanks for all the help
 
Alan Munn
Alan Munn
@Anush On my keyboard (Mac) it's just option-hyphen. But it's not needed with the \boldmath solution (and in fact shouldn't be used).
 
Anush
Anush
thanks
I am using lmodern
I wonder why my hyphen is longer than yours

I can I use lmodern for only one slide in beamer?
I mean one frame
 
Alan Munn
Alan Munn
@Anush You mean for the math? What fonts are you using generally?
 
Anush
Anush
@AlanMunn I use the default that beamer provides
 
Alan Munn
Alan Munn
@Anush But lmodern is basically the same. So you shouldn't notice too much difference. (Also use \usepackage[T1]{fontenc} in your preamble.)
 
Anush
Anush
thanks... what does that do?
I really mean, what does it improve?
 
Alan Munn
Alan Munn
4:55 PM
@Anush If you're using pdflatex then you need it to render accented characters properly for example.
 
Anush
Anush
ah right. Thanks
I am using pdflatex
or cislatex as no one calls it
what is the right way to typeset iff in LaTeX? As in if and only if.
 
Alan Munn
Alan Munn
@Anush For example, try this document with and without fontenc loaded: 
\documentclass{article}
\usepackage[T1]{fontenc}
\begin{document}
< >
\end{document}
 
Anush
Anush
! ?
:)
 
Alan Munn
Alan Munn
@Anush ¿ ¡
:)
@Anush I'm not a mathematician, but I would probably use \DeclareMathOperator{\Iff}{iff}. You can't use \iff since it's already defined as ⟺
 
Paulo Cereda
Paulo Cereda
5:12 PM
@AlanMunn I see what you did there. :)
 
Alan Munn
Alan Munn
@Anush But that's really only if you're using it math mode directly in things like 𝛷 iff 𝛹. If you're using it inside regular text then you can just write iff directly.
@Anush But don't take my word for it. Others may have a more authoritative answer.

5:35 PM
@AlanMunn or \DeclareMathOperator{\IFF}{if{}f} if you don't like the ligature there...

@DavidCarlisle it seems that storing a pdf in a temporary box before including it with \includegraphics is triggering some font optimization in pdftex: tex.stackexchange.com/a/562670/2388

@Skillmonlikestopanswers.xyz I have a nasty interaction in my audio output when luminosity changes a lot on the screen (desktop self-built tower 8+ years ago). Firefox triggers it a lot by scrolling, but not only it. I supposed it was some flaky connection or bad ground...
Had to switch to BT output, with all the connected problems :-(
 
David Carlisle
David Carlisle
@UlrikeFischer yes I saw something about file sizes...
@UlrikeFischer is it really the box, or not using the page= that makes the difference?
 
Ulrike Fischer
Ulrike Fischer
5:55 PM
@DavidCarlisle not using page= is required too. But only using the graphics doesn't work, it has to be a setbox command (it works in the document body too).
@DavidCarlisle the "big bib" breaks for me too and also on texlive. It looks as the library used to decode the file has problems with large files.
 
David Carlisle
David Carlisle
@UlrikeFischer 32bit binary?
 
Ulrike Fischer
Ulrike Fischer
@DavidCarlisle texlive yes, but miktex is imho 64 bit (at least I hope, I always forget this ..., but the binaries are in "x64") and it breaks too.

JakeThis is meant to be an addition to Caramdir's answer, but I cannot figure out how to insert line breaks into comments: To make it easier to find the desired points in the new coordinate system, you can draw a labeled grid on top of the image while you're working on it: \draw[help lines,xstep=.1...

Just downloaded my universities LaTeX thesis template
"The SFU thesis LaTeX project is a volunteer effort made by many SFU graduate students over the years. Thanks to the following students who contributed to the old template: Stephen Chan (1989), Margaret Sharon (1996), Pepe Kubon (1997-98), Greg Baker (2003-06), Chris McIntosh (2011), Bradley Coleman (2012), Juan Galvez (2012), Firuz Demir (2013), Ahmed Saad (2013), Reynaldo Arteaga (2014). Version 2.0 of the template was written by Ross Churchley (2014-15)."

Q: Is the TeX typesetting free and open source?

James FennellI recently opened the source code for the widely-used TeX typesetting system, and was surprised by the restrictive license I found: This program is copyright (C) 1982 by D. E. Knuth; all rights are reserved. Copying of this file is authorized only if (1) you are D. E. Knuth, or if (2) you make a...

@MartinSchröder -- Oh, sigh. TeX existed before the concept of open source was defined. It is stated (although I can't remember exactly where) that the algorithms and any code from TeX can be used with no strings in any other software, free or commercial. (At the time, that was quite radical.) The only restriction is on the change of name if changes are made to the Knuth-maintained code. The real purpose is to avoid confusion among users; they can always be sure of getting the same thing.
