Hi... Is anybody online here?
 
@EnthusiasticStudent Yes :-)
 
yo'
@EnthusiasticStudent no :-p
 
8:34 AM
@JosephWright thanks @yo' :D
I am writing an answer for a question on site
my code is something like this till now:
% pdflatex
\documentclass{standalone}
    \usepackage{siunitx}
    \usepackage{tikz}
    \usepackage{pgfplots}

\begin{document}
\begin{tikzpicture}
       \pgfmathdeclarefunction{q}{2}{\pgfmathparse{(4.9/(#1^2))*(cosh(#1*#2)-cos(#1*#2)}}
\begin{axis}
	\foreach \w in {0.1,0.2,...,1.0} {
	\edef\temp{\noexpand\addlegendentry{\w}}
	\pgfmathparse{100*\w}
	\xdef\x{\pgfmathresult}
	\edef\temp{\noexpand\addplot [red!\x]}\temp{q(\w,x)};
	}
\end{axis}
\end{tikzpicture}
\end{document}
 
yo'
@EnthusiasticStudent as you see, I and @Joseph are in agreement here :)
 
My problem is that I can not see the legend which is added in the iteration.
What should I do?
@yo' We are all in agreement :))
@DavidCarlisle Thanks for your answer here: tex.stackexchange.com/a/238291/52417
 
@EnthusiasticStudent don't you want to use the \addlegendentry ? you just use it in the definition of \temp but you redefine \temp to something else before using that definition
 
@EnthusiasticStudent For a start, it's the wrong side of \addplot
 
@EnthusiasticStudent as noted in the chat above yesterday it's bound to be better to iterate over 1,2,... and divide by 100 when needed rather than iterate over .1, .2.... which is forced to introduce rounding artefacts as you can not store .1 exactly in a binary system.
 
8:42 AM
@DavidCarlisle I want it... Should I bring it in the same temp definition? What is this temp? Sorry my question seems childish I think... :-(
 
@EnthusiasticStudent it's just an arbitrary name defined there temp = temporary, but you have essentially \def\foo{a}\def\foo{b}\foo and then ask why you only get b and not a
 
@EnthusiasticStudent For example
\documentclass{standalone}
\usepackage{expl3}
\usepackage{pgfplots}
\ExplSyntaxOn
\cs_new_eq:NN \fpeval \fp_eval:n
\ExplSyntaxOff

\begin{document}
\begin{tikzpicture}
       \pgfmathdeclarefunction{q}{2}{\pgfmathparse{(4.9/(#1^2))*(cosh(#1*#2)-cos(#1*#2)}}
\begin{axis}
	\foreach \w in {10,20,...,100} {
	  \edef\temp{\noexpand\addplot [red!\w]}\temp{q((\w/100),x)};
	  \addlegendentryexpanded{\fpeval{\w/100}}
	}
\end{axis}
\end{tikzpicture}
\end{document}
I've moved the legend after the plot and as @DavidCarlisle suggests done iteration using integers
Or keeping the range for \w
% pdflatex
\documentclass{standalone}
\usepackage{expl3}
\usepackage{pgfplots}
\ExplSyntaxOn
\cs_new_eq:NN \fpeval \fp_eval:n
\ExplSyntaxOff

\begin{document}
\begin{tikzpicture}
       \pgfmathdeclarefunction{q}{2}{\pgfmathparse{(4.9/(#1^2))*(cosh(#1*#2)-cos(#1*#2)}}
\begin{axis}
	\foreach \w in {0.1,0.2,...,1.0} {
	  \edef\temp{\noexpand\addplot [red!\fpeval{100 * \w}]}\temp{q(\w,x)};
	  \addlegendentryexpanded{\fpeval{round(\w,1)}}
	}
\end{axis}
\end{tikzpicture}
\end{document}
@EnthusiasticStudent I've used the LaTeX3 FPU as it's expandable (and doesn't have the rounding issues of the pgf one)
 
@DavidCarlisle It does not solve by changing the name of the temp to temp1 and temp2...
 
@EnthusiasticStudent not surprising as you can't have digits in command names

Q: Defining commands/abbreviations that contain numbers

Leo AlekseyevI tend to use \newcommand to define macros for symbols I use often, e.g. \newcommand{\hankel}{H^{(1)}_0}. One inconvenience of this approach is the fact that command names cannot include numbers. What I ideally want is to map something like \H0 to H^{(1)}_0. I imagine this could be done with s...

 
8:51 AM
@JosephWright when you have a spare moment you should implement tikz-over-l3 instead of tikz-over-pgf
 
@JosephWright Good question... thanks...
 
@DavidCarlisle Is on my list (really: some low-level set of instructions on which picture mode, TikZ or whatever could be set up)
 
@JosephWright yes seems like it's inevitable in the end..
 
@DavidCarlisle another problem was that I have not closed the first temp by putting a \temp at the end of its statement
 
@EnthusiasticStudent as I said, you defined it but never used it (it doesn't matter that you later redefine it with the same name)
@EnthusiasticStudent \def\foo{a}\foo\def\foo{b}\foo works fine and makes ab
 
yo'
8:55 AM
@DavidCarlisle Is there a way how to define a "transparent" color mycolor so that \color{mycolor} actually doesn't do anything?
 
@yo' not really, you can reset the current colour if you know what that is or you can use \iffalse\color{anything}\fi
 
@DavidCarlisle can those two legendentry and addplot be defined in the same temp?
 
yo'
@DavidCarlisle well, the point is that I wanted to simply use a color and let the user re-define it. I'll introduce my own interface :)
 
@EnthusiasticStudent yes if you want but why?
 
@EnthusiasticStudent You don't need to force expansion for the legend in this way: see my example where I use \addlegendentryexpanded
 
9:01 AM
@DavidCarlisle I think it would be easier for me to understand it...
 
@JosephWright no note from Petra about base yet?
 
@JosephWright yes...
 
@DavidCarlisle I had a series of e-mails from Manfred Lotz: all seems OK
@DavidCarlisle ctan.org/pkg/latex-base showing correct date
 
@JosephWright to you not latex-team I guess: tut tut:-)
 
@DavidCarlisle I'm working through that e-mail 'wall'!
@DavidCarlisle It's not my fault
 
9:06 AM
@JosephWright oh no the tutting was to Manfred:-)
 
@DavidCarlisle I didn't check the 'to' on the mails: there were a load!
@DavidCarlisle All of the bits and pieces did get installed
@DavidCarlisle I guess LaTeX will get updated in TL'15 for the first day of pretesting!
 
@JosephWright good! I'm about to vanish for a two day course (starts in 20 minutes:-) so might not be around so much during the day.
 
It looks ugly indeed... does not it?
 
yo'
@EnthusiasticStudent have you considered mixing e.g. red and green to get a gradient?
 
9:11 AM
@yo' Like what @DavidCarlisle did in his answer? tex.stackexchange.com/questions/238290/…
 
yo'
@EnthusiasticStudent prrbly? I dunno :)
and I gotta go, see you later
 
@yo' I did... looks better. See you.
@JosephWright can I ask another question? ....
@DavidCarlisle I have another problem with that floating thing...
Everyone got tired of my questions :( have a nice day
 
9:28 AM
This question is a bit scary. Even more scary is, that by reading the title i thought: Poison the damn drinking water.

Hi. I thought using the url package, and wrapping a url in \url would break the url across lines but that doesn't seem to be happening here. Am I wrong about the above?
 
10:52 AM
@FaheemMitha Are there things to break it? hyphens for example? if so, pass option hyphens to the package.
@FaheemMitha If just letters (no punct) you can add letters to the list of breakable charackters. An example is in the manual.
 
@Johannes_B I tried passing options hyphens, but it didn't seem to have an effect.
I did find:
80
Q: Forcing linebreaks in \url

SureshI wish to typeset some relatively long URLs in a piece of text, and when I use \url{..}, the resulting text does not respect the margin boundaries that govern the main text body, instead going all the way to the edge of the paper before wrapping around. For reference, my preamble looks like thi...

I had earlier upvoted one of the answers. :-)
There is an =, ? and / in there.
It's mostly letters though.
 
@FaheemMitha Did you resolve the issue?
 
@Johannes_B Well, it split on an = sign, but the second line of the url still overruns into the margin. It's a really long gibberish filled url. But I printed it and the entire url is printed. I guess the other option is to allow splitting on regular characters.
 
@FaheemMitha Yes. Or using \href{sooomecrazyurl.org}{Short descr}
 
11:10 AM
@Johannes_B Or one could use tinyurl or one of its relatives. Any recommendations re those services?
 
Hello!! Which is the command in latex to create the table of the Ackermann's function en.wikipedia.org/wiki/Ackermann_function#Table_of_values or www-users.cs.york.ac.uk/susan/cyc/a/ackermnn.htm ??
 
@FaheemMitha Never seen or even heard of tinyurl, sorry.
@MaryStar tabular-environment?
 
11:25 AM
@PauloCereda Extremely! Although, I couldn't find the source code anywhere. Hopefully it will become available at some point. Should be very interesting for all of us TeXies.
 
11:35 AM
@morbusg I will keep an eye on it, certainly. I love Clojure and TeX, so this is a perfect combo for me. :)
 
@Johannes_B seriously?
 
@FaheemMitha seriously
 
11:53 AM
@MaryStar: maybe you meant the construct: \underbrace{2^{2^{\rddots2}}}_{n+3}-3 (where \rddots is \def\rddots#1{\cdot^{\cdot^{\cdot^{#1}}}})
 
12:10 PM
If he (tex.stackexchange.com/q/238346) were German I would recommend something like markuss-blog.myblog.de/markuss-blog/art/7548742/… but I do not dare...
 
Is there any way to reduce the decimals printed in graphs plotted by pgfplots or tikz?
 
oh, already deleted
 
@EnthusiasticStudent Of course
 
@JosephWright How?... I can not find a relevant question about this...
 
@EnthusiasticStudent I tend to use something like
  \begin{axis}
    [
      every x tick label/.append style  =
        {
          /pgf/number format/.cd,
           precision = 1,
           fixed,
           zerofill,
        },
here to have exactly one decimal place on the x-axis
You can set the options globally, depending on your requirements
@EnthusiasticStudent Example of your input?
 
12:14 PM
I am still having problem with that floating point... I can not solve it anyway...
% pdflatex
\documentclass{standalone}
\usepackage{tikz}
\usepackage{pgfplots}
\def\colora{red}
\def\colorb{blue}
\begin{document}
\begin{tikzpicture}
\pgfmathdeclarefunction{q}{2}{\pgfmathparse{(4.9/(#1^2))*(cosh(#1*#2)-cos(deg(#1*#2))}}
\begin{axis}
\foreach \w in {0.1,0.2,...,1} {

\edef\tempb{\noexpand\addplot [\colora!\x!\colorb]}\tempb{q(\w,x)};
}
\end{axis}
\end{tikzpicture}
\end{document}
 
Good maen ;-)
 
See.... :-(
 
@EnthusiasticStudent Ah, the legend not the axes
 
@JosephWright yes...
 
@EnthusiasticStudent You need to use a printing function on \w rather than just inserting \w, for example
\documentclass{standalone}
\usepackage{tikz}
\usepackage{pgfplots}
\def\colora{red}
\def\colorb{blue}
\begin{document}
\begin{tikzpicture}
\pgfmathdeclarefunction{q}{2}
  {\pgfmathparse{(4.9/(#1^2))*(cosh(#1*#2)-cos(deg(#1*#2))}}
\begin{axis}
  \foreach \w in {0.1,0.2,...,1} {
    \pgfmathparse{100*\w}
    \edef\x{\pgfmathresult}
    \edef\temp{\noexpand\addplot [\colora!\x!\colorb]}\temp{q(\w,x)};
    \edef\temp{\noexpand\addlegendentry{\noexpand\pgfmathprintnumber{\w}}}\temp
}
\end{axis}
\end{tikzpicture}
@EnthusiasticStudent Or you could force \w to take the 'right' values, of course
I'd probably force 1 to 1.0 and tidy up a little more
\begin{axis}
  \foreach \w in {0.1,0.2,...,1} {
    \pgfmathparse{round(\w)}
    \pgfmathparse{100*\w}
    \edef\x{\pgfmathresult}
    \edef\temp{\noexpand\addplot [\colora!\x!\colorb]}\temp{q(\w,x)};
    \pgfkeys{/pgf/number format/.cd, fixed, precision = 1, zerofill}
    \pgfmathprintnumberto{\w}{\temp}
    \addlegendentryexpanded{\temp}
}
\end{axis}
 
12:31 PM
@JosephWright I am using SI package too... It seems to work, I think...
 
@EnthusiasticStudent Well you could use \num here from siunitx, but you certainly don't have to
 
@JosephWright exactly... I am using the \num
 
@EnthusiasticStudent So something like
\documentclass{standalone}
\usepackage{tikz}
\usepackage{pgfplots}
\usepackage{siunitx}

\def\colora{red}
\def\colorb{blue}
\begin{document}
\begin{tikzpicture}
\pgfmathdeclarefunction{q}{2}
  {\pgfmathparse{(4.9/(#1^2))*(cosh(#1*#2)-cos(deg(#1*#2))}}
\begin{axis}
  \foreach \w in {0.1,0.2,...,1} {
    \pgfmathparse{round(\w)}
    \pgfmathparse{100*\w}
    \edef\x{\pgfmathresult}
    \edef\temp{\noexpand\addplot [\colora!\x!\colorb]}\temp{q(\w,x)};
    \addlegendentryexpanded{\num[round-mode = places, round-precision = 1]{\w}}
 
@JosephWright Can I use the above solutions of yours, in my answer to a question? Of course I will provide relevant links to your chat messages to refer to you...
 
then?
@EnthusiasticStudent Sure
 
12:35 PM
% pdflatex
\documentclass{standalone}
\usepackage{siunitx}
\sisetup{scientific-notation = true,round-mode=places,round-precision=1}
\usepackage{tikz}
\usepackage{pgfplots}
\def\colora{red}
\def\colorb{blue}
\begin{document}
\begin{tikzpicture}
\pgfmathdeclarefunction{q}{2}{\pgfmathparse{(4.9/(#1^2))*(cosh(#1*#2)-cos(deg(#1*#2))}}
\begin{axis}
[
axis lines = center,
grid=both,minor tick num=1,
xlabel=$x$,ylabel=$q$,
tick align=inside,
every axis y label/.style={rotate=0, black, at={(0.5,1.05)},},
Here was is my solution @JosephWright
 
@EnthusiasticStudent Since everything is 10^{-1}, couldn't you simplify your legend?
 
@PauloCereda I changed it to: \sisetup{round-mode=places,round-precision=1} and it now prints: 0.1, 0.2, 0.3, 0.4, .... exactly what it should be printed.
 
@EnthusiasticStudent Good call.
Plots, the simpler the better.
 
@PauloCereda Quite
 
@JosephWright :)

@JosephWright @DavidCarlisle @PauloCereda I have to thank you. I learn so many points about latex from you, today.... Thank you...

@DavidCarlisle Yesterday your macro for checking if the next char is \UTFviii@two@octets (or three) was triggered by \expandafter\something. Now imagine that I want to do that “after grabbing some argumens” (sorry if this question is too basic, but I don't know right now).
I..e., \ifnextunicodechar{»}{True}{False} I want an \expandafter after the three arguments.
Okey, since there's no need for it being expandable, it's easy, just \def the true and false branches :)

Enthusiastic StudentFirst of all, I want to thank you for asking this question; I am a basic user of LaTeX and by thinking about your question, I learned so many things. Here is the code and my solution to your problem; % pdflatex \documentclass{standalone} \usepackage{siunitx} \sisetup{round-mode=places,...

 
@EnthusiasticStudent Why tired?
 
@EnthusiasticStudent: Answering is recreation, not labour ;-)
 
@EnthusiasticStudent you probably should specify clearly which version is your desired/preferred version.
 
3:42 PM
@FaheemMitha I did not know. I will do it for my newer answers...
@FaheemMitha I spent about 8 hours to answer the question. I am a basic user and do not have so much experience in LaTeX.
@ChristianHupfer Yes... I feel really well after learning something new about LaTeX...
 
Yay I will get Mortal Kombat X tomorrow!

@ChristianHupfer Yes, thank you. :)
 
4:12 PM
hey all - following this post tex.stackexchange.com/q/238301/69118 It seems that an appropriate course to take would be to completely uninstall tex from my system and reinstall from the official site (I'm on Ubuntu, the package is behind). Would be cool to hear any thoughts on that, good plan?
 
@user3130747 OS?
 
Always those questions about TeX and ubuntu... seems to be a real mess - up on Ubuntu.
 
@EnthusiasticStudent Wow, that's a lot of time.
@EnthusiasticStudent You can edit your answer. :-)
 
Ubuntu 14.04 @Johannes_B.
 
@EnthusiasticStudent that's a strange thing to think.
@ChristianHupfer How so?
 
4:15 PM
@ChristianHupfer I think the official packages are a bit behind yeah :/
 
@user3130747 That should come with an (relatively) up-to-date TeX Live. maybe you got an old version somewhere else lying areound. What doe which pdflatex give you?
 
@FaheemMitha: I have no idea. I have not installed Ubuntu for years. Still using SuSE (blush) and vanilla install from TeXLive (the whole nine yards, of course)
 
@Johannes_B pgf -> 2.10 tikZ -> 2.10
 
@user3130747: Official packages? Does Ubuntu provide patched packages?
 
@ChristianHupfer It's Norbert's TeX Live packages, I expect. I use them too.
 
4:18 PM
@ChristianHupfer SuSE = Respect.
:)
 
@ChristianHupfer, not too sure, they have a PPA, I haven't looked in there yet, maybe I can push things to the newer versions that way rather than deleting and then upgrading. Not used that before
 
@PauloCereda: Irony? :-P
 
@ChristianHupfer Nope, I like SuSE. :)
 
@PauloCereda: SuSE 12.3 :D
 
@FaheemMitha yep
 
4:19 PM
@ChristianHupfer Cool. :)
 
@user3130747 which pdflatex i want to know the path of the executable
 
@PauloCereda: And my new machine still not completely setup .. standing in the corner, alone, unused ... sob
 
@Johannes_B, I'm not too sure what you mean, where the programme is on the system?
 
@user3130747 Do you know how to open a terminal/console/command line?
 
@Johannes_B yeah I'm fine with that
 
4:20 PM
@PauloCereda: You know ... the Fedora machine ;-)
 
@user3130747 Please open one and show the output for which pdflatex
 
@Johannes_B I'm not sure if you mean something in /usr/share something something
ok cool :)
@Johannes_B it's /usr/bin/pdflatex
 
I've never had a problem with the Debian TeX Live packages.
Except that they are kind of old, of course.
 
@user3130747 Ah, sure, repo installed. I was expecting something different.
 
@ChristianHupfer :)
 
4:23 PM
The wheezy ones are 2012 for example.
 
@user3130747 Can you just update vie apt-get?
 
@FaheemMitha I was trying to use a tikZ drawing that I don't think I'm able to with the current setup, this post tex.stackexchange.com/questions/238301/… has the links to the drawings. TikZ 3.0 isn't in the current packages I don't think?
 
@user3130747 Could you show the output of pdftex --version?
 
@Johannes_B yeah, I don't think that will get anything newer, I'll run it now though.
 
@FaheemMitha Ubuntu 14.04 should have at least 2013. I think pgf 3.0 was out then?
 
4:24 PM
@PauloCereda: Perhaps I will have more time if my promotion run is successful... or even less, depending on the possible new assignments ;-)
 
@user3130747 Which package is that?
 
@ChristianHupfer :)
 
@Johannes_B Perhaps. I don't use Ubuntu. I use Debian.
 
@PauloCereda -> pdftex --version here : paste.ubuntu.com/10816848
 
@PauloCereda: Are you heading to the TUG meeting in Darmstadt? I can't come, unfortunately. :-(
 
4:26 PM
@Johannes_B I think it might have been later than that that it was on CTAN and that, I'm not too sure, I'm just going off a few posts Ive bumped into over the last twenty minutes. I think 2014, might be completely wrong though
 
Cooking time...
 
@ChristianHupfer I cannot afford the prices, I'm sorry. :(
 
@ChristianHupfer tfl?
 
@user3130747: apt-get install texlive-pictures does something for you?
 
@Johannes_B: MFG???
 
4:27 PM
@user3130747 Many users on Debian just install vanilla TeX Live from TUG.org
@ChristianHupfer tasty fried liver
 
270 MB on that apt-get O.O, I'm sure I ran it last night
 
@Johannes_B yummy!
 
tasty liver? ;-) Sorry, I have to ... run away...
 
@Johannes_B @Johannes_B yes, that's what I'm thinking about at the mo, whether I'd be better off wiping the system of tex installs and going from there. I'm not sure if it's something that would mess anything else up or not though
 
@PauloCereda: What a pity. Perhaps the next meeting then
 
4:29 PM
@ChristianHupfer Indeed.
 
@PauloCereda @PauloCereda I'll try that in a sec, thanks
 
I could try and go for DANTE or GuIT meeting.
 
Away from keyboard
 
@ChristianHupfer oh no!
 
@user3130747 Could be that you have two different installs and the wrong one is in the path. Can't be sure though.
 
4:31 PM
@EnthusiasticStudent tell us (in the answer) what version of your script to use, and if it works, I'll upvote you. Deal?
 
@Johannes_B, that's a good shout, sounds like something appropriately daft for myself.
 
@EnthusiasticStudent tried the last version. looks good, but you really should move that legend out of the way.
 
@ChristianHupfer google.de/…
"you got tasty fried liver," he said. His tone let me know it wasn't anything to look forward to.
 
4:53 PM
@PauloCereda just finished updating, apt-get install texlive-pictures was already installed though
 
@user3130747 What's the error you are getting again? I probably should've asked this before. :P
 
@PauloCereda ha no worries, the post probably explains it better and it's only short : tex.stackexchange.com/questions/238301/…
 
@user3130747 I got that, but what's the error you get? Could you post the log for us?
 
@PauloCereda yeah sos, I'll open it up again and post the outputs, 2 secs
@PauloCereda its the error from tikz about the tikz file, heres a link to a snip of the out put : paste.ubuntu.com/10817106
I thought I'd put that in the OP actually, just edited it in now! whoops

@user3130747 google suggests that error is expected if you have pgf 2 installed and the document needs pgf version 3
 
@DavidCarlisle Yeah that seems to be the case. I originally came to this chat asking for advice about uninstalling tex from my system and reinstalling from the official website, that was a few messages ago now though :) I have installed via Ubuntu repos, which seem to be a bit behind
 
5:25 PM
@user3130747 what version in Ubuntu?
 
@FaheemMitha 14.04, seems I left a lot out of the OP, sorry !
 
@user3130747 no, I mean what TL version?
 
@FaheemMitha oh, TeX 3.1415926 (TeX Live 2013/Debian)
 
@user3130747 Ah, 2013. You could just dpkg -l | grep texlive.
 
@FaheemMitha yeah, i haven't used dpkg much i forget about it! a few things come up from that though : paste.ubuntu.com/10817208
 
5:34 PM
@FaheemMitha In this case, asking for --version would be more effective since we would find out the binary in path priority.
 
@PauloCereda I don't follow. --version of what?
 
@FaheemMitha Aren't we talking about TL?!
 
@PauloCereda we are.
 
5:53 PM
I've posted a question to the Ubuntu forum about this, as I think what I'm concerned about is breaking things through uninstalling the wrong things. I'm still not sure if an uninstall is the right approach or not
 
@PauloCereda Why?
 
@ChristianHupfer you are back. <3
 
@PauloCereda: Only physical... mentally I am still somewhere else ;-)
I will return later on
@Johannes_B: Tasty fried liver... the favorite meal of Hannibal Lecter ;-)
 
6:08 PM
@PauloCereda I think this is what I'll be doing askubuntu.com/a/486413/381385
 
@JosephWright Was just reading about en.wikipedia.org/wiki/Karen_Wetterhahn
Nasty business. Never heard of it before, though.
Hopefully you don't do such dangerous things.
 
@FaheemMitha Yes, happened during my degree
 
@JosephWright Oh, so you know about it?
 
@FaheemMitha Yes, it was big news
 
Well known in the community, is it?
 
6:10 PM
@FaheemMitha Yup
 
@JosephWright Oh. I guess I'm terribly ignorant. Horrible thing.
Are you actually an experimental chemist?
 
@FaheemMitha Yes
 
@JosephWright Oh. Well, I hope you are careful. :-)
 
@FaheemMitha Yes
 
@JosephWright :-)

Hi guys...
One the users on Graphics.SX seems to be ready to design a promotions ads image for TeX.SX
He is now on that site's chatroom and is asking about our expectations of such image
how should I answer this question?
 
in The Ink Spot, 21 mins ago, by Dom
@Johannes_B I'm happy to do something super quick, not a logo but a site ad, just need the text you want, font you want, and logo
For reference ^^^^^^^^
 
@EnthusiasticStudent Again, I believe things should be community-driven. So, at the end of the day, it's the community as a whole which will decide if things should be carried on and on which terms.
 
8:06 PM
@PauloCereda He is doing just a draft. Community can vote on it in meta.
@PauloCereda Do you have the feeling that I am imposing my idea of having a promotions image to TeX.SX community?
 
@EnthusiasticStudent Ah ok. :)
 
If so, I will stop my tryings...
 
@EnthusiasticStudent No, not at all. :) Please don't take my words too seriously, if they somehow got misinterpreted! I just pointed out that things might not be so simple as they appear to be, and one needs to proceed with care.
@EnthusiasticStudent: so far you are doing fine. :) I just said that, for example, people might not buy the ad idea, and as a result you could get sad, or even the bloke who's doing the drawing, or other people that put their efforts into it.
An example: I once thought of starting a podcast series in the TeX.sx blog. Quickly I found out it was not something the community wanted.
@EnthusiasticStudent: out of curiosity, have you ever talked to someone at Academia.SX to hear their feelings towards a sister-site promotion? And possibly, TeX.sx in particular? They might have something to say.
It's way more common for them to have these promotions. :)
@Johannes_B Comic Sans, bold, italics, all caps, Site about TeX and friends text, please. :)
A duck version of Negative Nancy. :)
I think I'm the one who needs to STFU. :)
 
8:21 PM
@PauloCereda You're receiving a visit of the Spanish Inquisition, watch out!
 
@egreg I wasn't expecting the Spanish Inquisition! :)
 
@PauloCereda It's the up to the TeX community to accept the idea or not. But in my opinion, there are some people who like the idea. Because I can see that two recent questions of mine about the promotions image for TeX have received a total number of 20 votes together...
 
@PauloCereda Who does? But you pronounced the heretic words! Repent!
 
Also, one of the users of this site who is a member of Academia too, posted a positive comment to one of the questions
@EnthusiasticStudent Nice idea. I don't have a picture to add, if you have one, you can add it there, it'll very likely get enough upvotes soon :) — yo' 2 days ago
 
@EnthusiasticStudent That's good, because once the ad is there, it's the Academia people who need to vote for it, not us anymore. :)
@egreg All caps? :P
 
8:24 PM
By the way, I do not really take these as signs that the TeX.SX community really likes the future image for promotions...
Because first it is posted on meta and users on TeX.SX will vote on it whether they want it to be their promotions image
 
@PauloCereda Torquemada is coming!
 
and then it will be posted by enthusiastic users to other promotions page of other Stack Exchange websites and users of those sites will decide whether they want site advertisement on their site or not...
 
@egreg Great, now the song is stuck in my head! :)
 
So the overall process is based on the communities tastes...
And yet, I really do not want to impose my ideas at all...
 
@EnthusiasticStudent So how about writing these lines in your questions? It's a way of people actually knowing things.
:)
As for me, you won't hear anything else from me, as it appears I am the Negative Nancy of this story. :)
 
8:27 PM
That user has designed a background or a base for a promotions image.
He will work on it...

@EnthusiasticStudent , @Johannes_B what's the famous latex typeface called, and is it freely available?
 
@EnthusiasticStudent Computer Modern.
 
@PauloCereda Is it freely available?
 
@EnthusiasticStudent Yes, but for non-TeX applications Latin Modern is rather more accessible
 
@PauloCereda Did you learn TeX - LaTeX by attending classes or you self-studied it?
 
8:41 PM
@EnthusiasticStudent I tried very hard to understand, banged my head against my table a couple of times, had some beers, read some tutorials, found this site, pestered @egreg, @DavidCarlisle and others, and I finally began to understand what I was doing here. :)
 
@EnthusiasticStudent You'll do well to find a course beyond the basics
 
@PauloCereda So I am at the beginning of my learning curve.
@JosephWright I know some of the basics... I can draw some graphs I need, typeset equations... But I am so upset that I am just a basic user.... I just find codes and samples on the net, edit them and try to solve my own problem.
 
@EnthusiasticStudent We are all in the beginning of the learning curve. :)
 
As an instance, today I really did not know anything about that expanding part, the temp part in my answer...
 
8:58 PM
@PauloCereda Speak for yourself. :P
 
Installing TL'15 pretest on my Windows rig
 
@JosephWright same here (cygwin) except we went out for post course dinner so I had to stall it for a few hours Installing [0688/3035, time/total: 04:14:50/16:50:33]: curve2e [395k]
 
@DavidCarlisle :-)
 
@DavidCarlisle No MacTeX just yet so I have to decide whether to wait for the native system
 
@JosephWright two day course on "customer facing skills" so well out of my comfort zone:-)
 
@DavidCarlisle Now we wait for the issues
@DavidCarlisle Indeed: what are they then?
 
@JosephWright tell you after tomorrow:-)
 
@DavidCarlisle Cool
@DavidCarlisle We make 'notable changes' :-)
 
Guys... do you have any idea of the images above?
 
9:11 PM
@EnthusiasticStudent I like them. :) Are those lions copyrighted?
 
in The Ink Spot, 14 mins ago, by Dom
@EnthusiasticStudent I'm haven't got time to look into the licenses for these images, I've added a couple, but I think you need to contact the image creators to see if you can use them, unless they're under a creative commons license

Q: TeX Lion logos and others

cacamailgIs there any compilation of TeX Lion (colored or monochrome)? I know the Lion in http://www.ctan.org/lion/. But I have already seen some nice (and colored) logos here, for TeX talks or interviews. It would be nice to have a compilation of them. Moreover, is there any other (La)TeX logos that c...

 
@EnthusiasticStudent: Nice images, indeed.
 
I guess they are copyrighted. :(
 
9:27 PM
@PauloCereda: Not really, only a referring statement to Duane Bibby is needed, if I interpret the ctan page correctly
 
@ChristianHupfer Ah I see. So images are licensed (better rephrased, I guess). :)
 
@PauloCereda: Well roared, lion ... er, duck ;-)
 
@StefanKottwitz: Whatever... I am not SE site maintainer/programmer etc. ;-)
@PauloCereda: Recently, the Marx Brothers enter my answers :D
@StefanKottwitz: Thanks for keeping me informed
 
@ChristianHupfer :-) just talking, don't worry
 
9:38 PM
@PauloCereda: I can hardly await LaTeX 4 as Alan Munn posted ;-) I am so excited...
 
@EnthusiasticStudent -- (arriving late at the party, i guess ...) the shapes of the "Q", "&" and "A" are such that if they are "evenly spaced", the "Q" looks much closer to "&" than "&" to "A". some kerning, please, for a nicer appearance.
 
@StefanKottwitz: Sorry, it was no joke. A real "thank you!"
 
@ChristianHupfer We all are!
 
From TL'15 pretest notes:
>LaTeX2e now incorporates, by default, changes previously included only by explicitly loading the fixltx2e package, which is now a no-op (CTAN announcement). A new latexrelease package and other mechanisms allow for controlling what is done. The included LaTeX News #22 and LaTeX changes documents. have details. Incidentally, the babel and psnfss packages, while core parts of LaTeX, are maintained separately and are not affected by these changes (and should still work).

Internally, LaTeX2e now includes Unicode-related engine configuration (what characters are letters, naming of primitives,
Karl Berry's paraphrasing of our release stuff
 
Because there may be issues on the copy right of the images used in that logo, I prefer not to continue to find a promotion image for TeX.SX....
 
9:40 PM
@PauloCereda: I've heard, that LaTeX 5 will even be better... ;-)
 
@PauloCereda I'm excited, that today my son passed a surgery well and is fine! :-))
 
@StefanKottwitz How nice! Glad to hear he's fine!
 
@StefanKottwitz So glad to hear that...
 
@StefanKottwitz: I hope, nothing serious?
 
@ChristianHupfer he got a blackened eye still :-) but he's driving his big dumper car through the complete hospital kind of a tumor near the eye was growing, now it's tidied. I'm so lucky
 
9:47 PM
@StefanKottwitz: Oh my! Glad to hear that the surgery was successful
 
@ChristianHupfer thanks! microscopic patho findings we'll see tomorrow, now it's great that he doesn't even need painkillers
half-eyed like a pirate, bleeding out of the nose, but fighting hard to get the iPad for a cartoon from mum :-D
 
@StefanKottwitz: I hope there is no bad result! "Daumen drücken!"
 
@ChristianHupfer Thanks! I'm sanguine. It's wow how one is feeling about the own child.
And even more, for me I noticed that I'm extremely sensible about any child hurt from the moment I got one myself.
 
10:04 PM
@StefanKottwitz: I've got no child yet, but even I can imagine that one is upset in such a period
 
@ChristianHupfer I got two and it makes life to so much more
Ok, back to TeX, and all news about LaTeX2e+1 and tlpretest 2015 :-)
what breaks?
what needs an update?
can I install TeX Live today or should I wait?
do I get the currrent status or is a net install from 2014 and updates frozen?
just loudly thinking
 
@StefanKottwitz I'm half way through an install and nothing broken so far:-)
