PdfLatex is a tool that converts Latex sources into PDF. This is specifically very important for researchers, as they use it to publish their findings. It could be installed very easily using Linux terminal, though this seems an annoying task on Windows. Installation commands are given below.

• Install the TexLive base

sudo apt-get install texlive-latex-base

• Also install the recommended and extra fonts to avoid running into the error [1], when trying to use pdflatex on latex files with more fonts.

Saving Your USB from Rufus Defaults

Don't pay the cost like I did. Large ISOs (>4 GB) + wrong settings = an unreadable USB or a wasted stick.

TL;DR

• UEFI system + 5.9 GB Ubuntu ISO $\Rightarrow$ Do NOT use default setup (FAT32, even though Rufus ISO includes many files each less than 4GB, I don't know why but it can break, probably regarding wrong logic, anyway, you shouldn't just throw it in with the default values without even reading it, just because you’re busy.).
• Use Rufus $\to$ DD Image mode (safest). Windows may not "see" the USB afterward-that's normal for boot media.

How to Configure Access for qcow2 in virt-manager

If you've created a qcow2 virtual disk, you might have noticed that it's not internally accessible even when you access it using sudo virt-manager. To fix this, we need to make a few changes to the /etc/libvirt/qemu.conf file.

1. Locate the Configuration File: The configuration file is found at /etc/libvirt/qemu.conf.

2. Modify the User and Group Settings: Find the lines that specify the user and group for QEMU processes. The default settings look like:

import re

def convert_latex(text):
    # (1) 블록 수식: \[ ... \] → $$ ... $$
    text = re.sub(r'\\\[(.*?)\\\]', r'$$\1$$', text, flags=re.DOTALL)
    # (2) 인라인 수식: \( ... \) → $ ... $
    #text = re.sub(r'\\\((.*?)\\\)', r'$\1$', text, flags=re.DOTALL)
    text = re.sub(r'\\\(\s*(.*?)\s*\\\)', r'$\1$', text, flags=re.DOTALL)

    return text
