Forget that, since the length of the A4 page allows to insert a "level" more of entities I avoid having to make bent lines (and in fact it is more homogeneous):

I don't understand why I'm getting this error, when trying to use minted within a beamer slide
OK - I needed to use [fragile], it works now

@manooooh Both diagrams are good, in my opinion! I even prefer the first one because there is less white space left, but it's only an aesthetic judgement, not technical. Thank you for accepting my answer!
 
@CarLaTeX you are welcome! Oh, I did the second one hihi. Note that there is no problem with vertical space, since the A4 sheet can with the diagram. But you are also right that there is a place without occupying
Meh
 
5:51 AM
@CarLaTeX I am having a little problem of bending a relationship
I want to draw the following:
MWE:
\documentclass{article}
\usepackage[utf8]{inputenc}
\usepackage[english]{babel}
\usepackage[T1]{fontenc}
\usepackage[a4paper,margin=1in]{geometry}
\usepackage{array}
\renewcommand{\arraystretch}{1.1}
\usepackage{tikz}
\usetikzlibrary{shapes.multipart}
\usetikzlibrary{positioning}
\usetikzlibrary{shadows}
\usetikzlibrary{calc}

\usepackage{pdflscape}

% code for "one to omany", etc. is taken from https://tex.stackexchange.com/q/141797/101651
\makeatletter
\pgfarrowsdeclare{crow's foot}{crow's foot}
I do not know how to tell the program to calculate the midpoint between entities B and C
And even if I do, I do not know if the relationship will be folded properly (I think it will continue to stick to the edge of entity A)
 
@manooooh You could easily do it with ++. For example, try \draw (a) -- ++(10pt,0) -| (b); where a is down on the left and b is up on the right.
 
@CarLaTeX hm, I do not understand
 
For the midpoint between B and C you can use ($(B)!.5!(C)$).
 
@CarLaTeX oh you are right. Can this solve something?
 
6:07 AM
@manooooh That command means draw a line from a to a point shifted 10pt on the x axis and than draw an L-shaped line from it to b.
@manooooh Of course, you can use: \draw (entityA) |- ($(entityB)!.5!(entityC)$);!
 
@CarLaTeX yes I am just testing
\begin{tikzpicture}
\pic {entitynoatt={A}{Entity A}};
\pic[right=5em of A] {entitynoatt={C}{\small Entity C}};
\pic[below=5em of C] {entitynoatt={B}{Entity B}};
\coordinate (AB) at ($(B)!.5!(C)$);
\coordinate (ABlink) at (B.north -| AB);
\draw[oone to none] (A.south) -- ++(0,-25pt) -| (ABlink);
\draw[one to one] (C.south) -- (AB);
\end{tikzpicture}
I cannot do \draw[oone to one] (A.south) -- ++(0,-25pt) -| (ABlink); because we did not create oone to one relationship!! hahah I was so close
Oh I found it!!!
\begin{tikzpicture}
\pic {entitynoatt={A}{Entity A}};
\pic[right=5em of A] {entitynoatt={C}{\small Entity C}};
\pic[below=5em of C] {entitynoatt={B}{Entity B}};
\coordinate (AB) at ($(B)!.5!(C)$);
\draw[oone to none] (A.south) -- ++(0,-25pt) -| (AB);
\draw[one to one] (C.south) -- (B.north);
\end{tikzpicture}
Izi peasy
 
@manooooh Good :):):)
 
@CarLaTeX thanks for suggesting me ++ option
I remember @marmot taught me about that command but now I do not remember lol hahaha
 
6:24 AM
@manooooh You're welcome!
@manooooh Read Section 3.2 here: tug.org/TUGboat/tb39-1/tb121duck-tikz.pdf
 
6:47 AM
@CarLaTeX \draw (multiply.east) -- +(.5,0) |- (join1); :)
I <3 Prof. van Duck!!
Solved
Does anyone know why when we add align=center to the options then we are able to insert a line break i.e. \\ to a node in TikZ? It is curious for me
 
7:05 AM
@manooooh And prof. van Duck <3 you!
 
@CarLaTeX wow what a full answer, essentially it is a \hbox and we can apply the same things to him that if he were not in a tikzpicture environment. Thanks!
 
@manooooh There's always an answer on our site :):):)
 
@CarLaTeX hm, I do not think so. Here is one: Why CarLaTeX is not an admin?
 
@manooooh Because I'm not so calm and quiet as @JosephWright or @StefanKottwitz. You know, I'm Italian, we are passionate :)
 
@CarLaTeX hahaha
@CarLaTeX do you really think that this is an excludent requirement? Do not you think there are some admins that are not (I do not know but I guess there will always be one)?
 
7:24 AM
@manooooh I think you should be diplomatic to be an admin, that's not exactly my profile... even if I'm learning, for example, to ignore silly comments by cocky users
 
@CarLaTeX does reading those comments leave you wondering why they say it during the rest of the day?
 
@manooooh No, I just don't care, and pay attention to not start a conversation with them
 
@CarLaTeX so what is your definition of "ignore silly comments"?
 
@manooooh For example, once I tried to answer a very unclear question and the user commented "This is just a minimal starting point. At least you would have done this thing and this other thing" and he downvoted me. I just deleted my answer writing "I hope someone else will answer". He immediately finished in my do-not-answer-to-these-ones list.
 
@CarLaTeX so what should you learn? You have done well, what else do you need to learn (besides "gaining patience")?
 
7:36 AM
@manooooh I learn not to reply "you should have asked a clearer question and not downvote someone trying to help you"
 
@CarLaTeX okay
 
@manooooh It would have started a fight
 
@CarLaTeX yeah
@CarLaTeX I really hope you can learn everything you want in the shortest possible time :)
@CarLaTeX hey one thing respecting your answer:
@CarLaTeX ^^^^ the cardinality "One" is shorter than the other options :(
 
@manooooh Wait, I'll correct it directly in the answer
 
I am trying to understand the definitions of one to oone, etc. but I cannot do anything, you know the code better
Also it happens with oone to none
And also with oone to oone
@CarLaTeX I hope to have done everything. LOL
 
7:51 AM
@manooooh I think it's no more necessary, lol
@manooooh Is it ok now?
 
@CarLaTeX yes, there were only 3 d*mn numbers, thanks!
 
The only changes are: `\pgfpathmoveto{\pgfqpoint{-4pt}{-6pt}}%
\pgfpathlineto{\pgfqpoint{-4pt}{-6pt}}%
\pgfpathlineto{\pgfqpoint{-4pt}{6pt}}`
6pt instead of 4pt
 
@CarLaTeX yes, I saw them using edited 2 mins ago :)
Well, time to sleep, the birds are singing
Goodbye!
 
@manooooh Good night!
 
8:24 AM
@samcarter yes it does. Perhaps some of them have a local install, too. They don't even have the latest/frozen TL2017, the first version of ducksay isn't included, which I published in September or October 2017.
 
9:29 AM
@JosephWright looks good, couple of typos in the para before the recommendation, its not it's and tied not tided
 
@DavidCarlisle Typos fixed (just rebuilding)
@DavidCarlisle Will tip of the team, and I think use it for a TUGboat
 
@JosephWright my suggestion of using l3fp for graphics didn't get universal approval:-)
 
@DavidCarlisle I hope the authors of the various packages I've skipped are OK about it! I did wonder about a 'special cases' paragraph, but I think that would dilute the message
@DavidCarlisle No? Did I miss an objection?
@DavidCarlisle Reminds me: I did wonder whether I should include trig
 
@JosephWright personally I'm devastated that trig.sty didn't even rate a mention:-)
@JosephWright ^^ ;)
 
@DavidCarlisle Could have a parenthetic sentence: 'There are also some very specialised packages, such as trig, which handle a very limited subset of mathematics'
 
9:38 AM
@JosephWright I wouldn't, to be honest
@JosephWright actually comparing trig the other day reminded me that trig is actually pretty accurate (not tan as that uses dimen divisiion sin/cos) but I spent quite some time scouring the literature for power series expansions of sin-in-degrees that used reasonable (for tex) integers in the rational coefficients:-)
 
@DavidCarlisle I can imagine
@DavidCarlisle I was pretty impressed that the FPU beats pgf for my 'simple' calculation test. Bruno did say he'd got the parser faster, which makes the difference.
 
@CarLaTeX you mean like "eat pineapple pizza" ?
 
10:11 AM
@DavidCarlisle No, that horrible comment cannot be ignored by any Italian

@egreg Hello very kind I sincerely hope that you are not angry with me for the comment I left about the three arrows on a new symbol. I send you my most sincere apologies and wish you a happy weekend.
@TorbjørnT. Good morning and have a nice lunch. Greetings from Sicily.
 
1:21 PM
@samcarter No problem, you can load the .sty in your projects :)
 
@CarLaTeX or use picture mode
 
@DavidCarlisle How many alternatives!
 
@Sebastiano Why should I be angry?
 
2:21 PM
@JosephWright -- sounds like a good idea. i've just read it, and have only one suggestion. in the second paragraph under "technical considerations", you say "integer mathematics". that doesn't make sense to me -- in the context, i can't envision anything but "integer arithmetic". (yes, i know, i'm being pedantic, but for a long time i've had the impression that most mathematicians aren't really good at arithmetic; ask frank.)
 
@barbarabeeton I concur: “integer arithmetic” is the correct terminology. About “most” I'd disagree, but “several” would be right. :-)
 
@barbarabeeton that's a correct impression. I can't do arithmetic, that's what brought me to theoretical maths :-)
 
2:38 PM
@boycott.se-yo' -- maybe those two skills are mutually exclusive. theory often eludes me, which is why i sometimes refer to myself as a "frustrated engineer" -- that and bias against females by some old-school pure mathematicians is why i ended up with an a.m. in linguistics.
 
@barbarabeeton I'm obviously being thick: the alternatives here are floating point or fixed point arithmetic (i.e. all real numbers, not just integer)
 
2:56 PM
@JosephWright -- but both fixed and floating point are arithmetic. there's no resorting to non-numeric concepts. to me, "mathematics" implies algebra, geometry, analysis, etc., etc. you said that yourself just now. (as i said before, i'm being pedantic. just a suggestion. but i didn't find any typos; @DavidCarlisle seems to have taken care of those.)
 
@barbarabeeton I've adjusted: keep you happy :)
 
@JosephWright -- have you seen this? nickhigham.wordpress.com/2018/12/03/… -- it addresses the fp problem head-on. don't know whether it might have any effect on your post, but since it came unbidden to my attention, thought it worth mentioning to someone who might be able to use it.
 
@barbarabeeton old university friend of mine:-)
 
@barbarabeeton Bruno is the man: our internal format is actually beyond the IEEE requirement ...
 
@DavidCarlisle -- he's written some good things about tex. that's how i got on his list.
@JosephWright -- thanks. nice to know.
 
3:09 PM
@barbarabeeton I can't imagine where he gets tex information from:-)
@JosephWright with respect to what I was saying about fp calculations and clock cycles, I note Nick's comment The NVIDIA V100 has tensor cores that can carry out the computation D = C + A*B in one clock cycle for 4-by-4 matrices A, B, and C I wonder how many clock cycles it takes to do that calculation if l3fp:-)
 
@DavidCarlisle :)
 
@DavidCarlisle -- the stuff he's written for siam is hugely better and more accurate than a particular self-styled expert (whom i won't name, but i'm not talking about mike spivak or george grätzer) has written for ams.
 
@barbarabeeton There's a reason i didn't come top in my year:-)
 
3:57 PM
@egreg I thought you didn't take advice. That's it. My most sincere greetings.

Hi, I'm writing a letter with the letter class. At the leftmost of the page, there is a horizontal little line. What's the reason for this?
 
7:01 PM
@AbdullahUYU -- just a guess ... it's probably a folding line, indicating where the paper should be folded to put into a window envelope. (not really familiar with the letter class, but have created form letters with this feature using plain tex.)
 
Oh, that's an interesting guess :) Yeah it can be ~1/3 of the page.
It can be useful to note that the screenshot doesn't cover the whole height of the page
 
7:55 PM
Hey guys!
Does anyone know how to use the following answer: tex.stackexchange.com/a/24767/152550 but that it automatically adjusts to the width of the page with text?
I tried with This is an exampleeeeeeee \underline{\hspace{\textwidth}} example but \underline{\hspace{\textwidth}} does not care if he has text behind or after him, so he always draws the line of the same length
(which is quite reasonable, but I would like to know if there is an automatic command that calculates the missing space)
 
8:30 PM
@manooooh This seems to be what \leaders is for, of which \hrulefill is but one example. Try first with \hrulefill and see if it does what you want; I am not really sure I understood your question, so may be off the mark here.
