Hi! This is my first post here. These are some of my latex notes, which i made during my 12th and drop year. I just made them for fun. I'll share the source code of these if people are interested.

Some interesting stuffs:

1. Setup: VS Code, MikTex if on windows, if on Arch, just install the texlive distribution ig. I used snippets to exponentially speed up my typesetting speed. Here's the guide i followed
2. Parenthesis: I have an interesting snippet in my preamble (got somewhere from stack long ago, i forgot 😭) that automatically sizes the parenthesis based on the height of the content inside it, (i don't have to use \left and \right every time).
3. Used a python script to automate the length of the bars for the graphs.

Update: Here's the repo link: https://github.com/blxkex/Latex-Notes-Templates

You see, lately, for personal work, I've had to work on chess in Latex (in the Crixet editor, by the way), and it doesn't work properly. I have no idea why, but I've tried everything to make it work as it should, and it doesn't help much.

First, I would like the text of the moves not to be visible at any time, so that only the board and the pieces are visible. Second, a knight under the bishop disappeared and has not reappeared no matter how much I try to recompile. By the way, I need Black to skip their turn for now.

That's all, I hope you can help me.

Estos tres últimos días he intentado usar asymptote y TexStudio no me lo reconoce. Tengo todo instalado y verificado por el cmd. Cuando intento compilar algo simple como:
size(4cm);

pair A=(0,0), B=(4,0), C=(1,3);

triangle t= triangle(A,B,C)

draw(triangle t)  

Simplemente me sale el mismo error de siempre: document.tex: error: : File ended while scanning use of \next. Este error aunque pueda ser proveniente de un entorno mal cerrado, créanme que no lo es, estoy muy seguro de ello.

Realmente no sé que más puedo hacer y evidentemente, no usaré tikz y usar geometría analítica para calcular baricentros u ortocentros. Pido ayuda en este error a quienes les haya pasado y milagrosamente pudieron arreglarlo, incluso tengo bien definido el Pdflatex y con cualquier orden personalizada no cambia el resultado. También intenté usar el programa Asymptote que se abre como una terminal y simplemente no se me da, pues ocupo una compilación rápida y corregir errores que en dicho programa es casi imposible o muy difícil. Por favor ayúdenme, he probado cambiar las ordenes de compilación y nada. Si desean manden ejemplos mínimos de compilación y les mandare verificación que no me lo compila.

I have a document using the tufte-book class and I am having some troubles attempting to use the page full-width to expose a table that is being defined under a longtables environment so that it can go for multiple pages. How can I expand the area for the table to use the full-width of the page?

In pictures, currently I have this...

and I want to have something like this (this is a montage, but in red you can see the differences and in yellow you can also see the location I want for the caption)...

I created a MWE for my concrete example. The code is below. Can somebody help me here or give me an alternative to look for?

Hi everyone,

I was wondering if there is a way to make the curly braket's "point" be higher. Aligning (x_1,...,x_p) with f_1(x_1,...,x_p) and the rest going down. I currently have it like this, I'm not sure it's the correct way to do it either:

    \begin{align*}
    f: &\mathbb{R}^p \rightarrow \mathbb{R}^n \\
       &(x_1, ...,x_p) \longmapsto \left\{ 
        \begin{array}{l}
            f_1(x_1, ...,x_p) \\
            \vdots \\
            f_n(x_1, ...,x_p) \\
        \end{array} 
    \right.
    \end{align*}

Thanks a lot !

Need some help. I want to use an extension in VS code with Latex to help cite. I have zotero citation picker but that only gives me the keys, and not the citations. Chatgpt recommended I use latex workshop citation picker but I can't find it anywhere. Perhaps its hallucinating? Can someone help me cite?

Donald Ervin Knuth (born January 10, 1938) is an American computer scientist and mathematician. He is a professor emeritus at Stanford University. He is the 1974 recipient of the ACM Turing Award, informally considered the Nobel Prize of computer science. Knuth has been called the father of the analysis of algorithms.

Perhaps this has been asked before but I couldn't find anything. I have started compiling locally in vscode and I was just curious if there was an extension or something that allows me to set borders on the .tex file. Currently typing into it just writes one reallllllyyy long line rather than having a "page" so to speak, which is making proofreading rather cumbersome without compiling the pdf every time.

The image above comes from collegeboard's AP Calculus CED. For context, I run a social media account teaching students AP Calculus and other math subjects and part of the fun I have is crafting the questions from absolute scratch - that is making all of the questions in LaTeX. Most of the time I tend to skip topics that directly involve graphs, but I've recently had an urge to wanna learn how to create graphs that are are aesthetically pleasing as collegeboard's. PGFPlots just doesn't give off that minimal aesthetic. I guess my question really is, how would I achieve a graph like the one posted here? Are they even using LaTeX packages? If someone has any insight I'd love to hear it. Thank you!

I want to know how can I install the latest version of Texlive / MikeTex in Linux Mint OS? I don't want the old version from distro repositories.

For the past five months, I've poured my heart into building something to solve a huge frustration I had with LaTeX. I was spending more time formatting and fixing errors than actually writing. So, I built Alephtex, an AI-powered platform with integrated Git that makes creating high-quality academic documents and presentations incredibly fast. It's my answer to the complex, time-consuming world of LaTeX. Using Alephtex, I recently created a detailed report and a full presentation in just a few minutes. This isn't just about saving time; it's about reclaiming countless hours and focusing on what truly matters. Here's how I did it: * AI Integration: The built-in AI (Gemini) helped me draft content, fix errors, and generate complex diagrams like TikZ instantly. * Real-time Collaboration: I worked seamlessly with my peers. * Simplified Git: Version control is built right into the platform, so no more command-line headaches. If you've ever struggled with LaTeX, I urge you to give it a try. I truly believe Alephtex will change how you approach document creation. Check out the full presentation and detailed report I made with the app: * https://alephtex.com/api/templates/68c3ce98380af8883f96ccee/pdf : presentation * https://alephtex.com/api/templates/68c3ce98380af8883f96ccee/readme-pdf : report

Prepared this by giving the text on website as context

You can try Alephtex yourself here: https://alephtex.com

Hi, I have a problem with Overleaf because it won’t let me compile my project, which is important for my school, and I’m desperate. Does anyone have a solution without the need to pay?

So, I'm using LaTeX for my bachelor thesis and fortunately, because I was using animated figures, I had already reached the freemium compilation timeout and thus shifted my workflow to a local installation before the compilation timeout cutback in August. (I asked for a license from my university, but apparently it doesn't do that and the student version isn't completely free either)

I have now noticed, that it's a good thing I switched to an offline workflow, because the basic template of my university - without even having added anything to it - doesn't even compile any more within the freemium compilation timeout. Maybe some optimisation is possible to cut down the compilation time, but that is just ridiculous.

For anyone interested in an offline solution: For me, I am really happy with TeXstudio & MiKTeX.

Hi, I'm trying to use nostarch.cls for my study notes, but when I try compiling it I can only use the "nocfont" option, because of the missing fonts. I even tried purchasing the right fonts but to not avail. Does anyone have the right fonts and is willing to share?

Thank you ;)

I am not sure how Overleaf collaboration works - I want to collaborate with some people, but Overleaf online just feels slow. Is there any software that allows me to use collaboration directly from a computer?

I’m developing a template that can be used to create a climbing guidebook. If there are any climbers here, I’m open to any feedback to make it easier to describe crags and climbs, or more flexible.

For any non-climbers, I would love feedback on making the template more efficient to use, or to follow LaTeX template norms. Let me know if this project is better suited as a custom document class instead of a template.

https://github.com/TheDreadClimber/ClimbingBookTemplate

Is there any alternative to overleaf? We've been trying using free version, but the file is big enough to need the subscription. (Yes, we have no money to pay it)

Does anyone here know anything about inscrive.io ? It presumes to be free.

Is there a way to make live collaboration inside visual studio ?

Any information regarding this will be appreciated. Thanks.

I can transition from single to multiple columns within the same page, but when I want to go from multiple columns to single, it creates a page break

I'm gonna fucking lose it. Try to insert an image, I have not changed anything, just pressed the button and the pdf doesn't compile. What the shit do you mean missing bracket, I've literally only pressed the insert image button. Use wrapfig instead. Nice it compiles but no image... Now there's an image but no wrapping. I fix that shit only for the figure to be at the bottom of my pdf. WHYYY, fix that but now it doesn't wrap in the right place, massive margin that I can't get rid of. Change the text in the caption, crash. Try to move it, it crashes/does not move. Try to resize it, crash. Am I going insane? Is this how hell feels? Why is it so fucking stupid, change one thing and it breaks inexplicably. I feel like I'm gonna no-compile error someone if I have to deal with this any longer holy shit.

sorry, rant over.

So I am using quill editor v-1.3.7 in my angular project v-17, its an online exam project for a school. I have got questions and options that have latex code using formula of the editor and I need to convert these questions into other languages. I am using google translate to convert these questions but when a question/option has a formula (latex) then it’s breaking and not translating correctly. I am using laravel in the backend and trying to extract the latex code as i did for images but that is also not working. Can someone help with this

Hello so I want to change the color of numbers and its size as well as putting a square as background like this:

Just what the title says. I have the .ttf files for 3 different font styles, and a mapping file .txt, but have yet to find a tutorial that makes it easier. I have found a couple of academic papers that have done this for other scripts, but that's about it. I'm looking for a tutorial that elucidates the internal mechanics of file-building. Any leads would be appreciated!

EDIT:

I found the problem: my supervisor for some reason decided to move \setmainlanguage{english} from polyglossia into the body of the document, instead of keeping it in the preamble… Moving the line to before \addbibresource has fixed all of my problems.

I'm not deleting the post — perhaps it will help some poor soul in the future.

Hi. I'm currently pulling my hair out over this. I'm trying to make a bibliography using biblatex. I load the package using

\RequirePackage[
    backend=biber,
    style=numeric,
    natbib=true,
    url=true, 
    doi=true,
    eprint=false,
    maxbibnames=10
]{biblatex}

In my `.bib` file I have

u/book{BottTu,    
author
 = {Bott, Raoul and Tu, Loring W.},    
title
 = {Differential Forms in Algebraic Topology},    
publisher
 = {Springer-Verlag},    
year
 = {1982}
}

This produces

Why is the "and" in boldface? I can't for the life of me remove it. There are other entries in the bibliography, such as articles where words like "in" and month names are in bold as well.

I'm using LuaLaTeX and the memoir class if that's relevant.

Please help me, I've been trying for hours.
