\subsection{Detail History}
\begin{frame}{Detail History}
\underline{\color{brown}History back to Typography (eg: \TeX) and Fonts}:\\
A well-respected computer scientist {\color{blue}\href{https://en.wikipedia.org/wiki/Donald_Knuth}{Donald Knuth}}:\\
\begin{itemize}
\item Published \textquotedblleft The Art of Computer Programming- Vol. 1\textquotedblright
\item Typeset in metal-typesetting system.
\item Publisher changed their printing technology into photo-typesetting.
\item In 30 March 1977, {\color{red}Disappointed} with the document quality of his book \textquotedblleft The Art of Programming- Vol. 2\textquotedblright.
\pause
\vspace{0.2cm}
\underline{\color{brown}Issue}:
\item Letter wasn't position accurately.
\item Some words are more darker than others.
\pause
{\color{red} In short, No quality control over the document.}
\end{itemize}
\end{frame}
%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
\begin{frame}{Detail History}
\underline{\color{brown} Inclined to think}:\
\begin{itemize}
\item During at Stanford, his community duty is to provide reading lists.
\item Same time 1977, he got a gallery proof of the book \textquotedblleft Artificial Intelligence\textquotedblright by {\color{blue}\href{https://en.wikipedia.org/wiki/Patrick_Winston}{Patrick Winston}}.
\pause
\underline{\color{brown} Trigger point}:
\item Prepared using the machine that was completely digital.
\item It was typeset using pixels which encodes 0 and 1.
\pause
\underline{\color{brown} Clue}:
\item High quality printing is the matter of computer program.
\item He saw it as in the form of computer problems.
\end{itemize}
\end{frame}
%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
\begin{frame}{Detail History}
\underline{\color{brown} Beginning of \TeX}:
\begin{itemize}
\item Created a digital typesetting system i.e. \TeX
\item {\color{orange}Pronounce} as: /'t$\varepsilon$x/ tekh or {\color{violet}/'t$\varepsilon$k/ tek}.
\item Named from greek word $\tau \varepsilon \chi$ which means art as well as craft.
\item In 1978, Shared his software within the Permissive software licence.
\item Current stable version of \TeX\hspace{0.01cm} is 3.14159265 ($\pi$ with 8 decimals) which means, it's in the 9th version.
\pause
\underline{\color{brown} Advantage}:
\item Gives extensive control of document layout.\\
\underline{\color{brown} Users using \TeX}:
\item \TeX\hspace{0.01cm} users were growing and they extended the macros.
\pause
\vspace{0.2cm}
\underline{\color{brown}Issue}:\\
\item Not easy to use !
\end{itemize}
\end{frame}
%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
\begin{frame}{Detail History}
\underline{\color{brown}Invention of \LaTeX}:
\begin{itemize}
\begin{tcolorbox}
\item Date back to 1985, {\color{blue}\href{https://en.wikipedia.org/wiki/Leslie_Lamport}{Leslie Lamport}} releases \LaTeX\hspace{0.01cm} to the modification of \TeX.
\item Aims to have a easy to use document preparation system.
\item \LaTeX\hspace{0.01cm} = \textquotedblleft {\color{purple}Lamport's \TeX}\textquotedblright
\item {\color{orange}Pronounce} as: /'la:t$\varepsilon$x/ LAH-tekh or /'leIt$\varepsilon$k/ LAY-tek or {\color{violet}/'la:t$\varepsilon$k/ LAH-tek}
\item Encloses with High Level Markup Language, which is syntactically distinguishable from the text.
\item File extension: {\color{blue}\textsf{*.tex}}

\begin{itemize}
\pause
\item High typographical quality of the document.
\pause
\item \LaTeX \hspace{0.1cm} allows users to clearly separate the content from the format of the document.
\pause
\item It gives user the opportunity to focus on \textquotedblleft what\textquotedblright the creative part of your work, rather than \textquotedblleft how\textquotedblright is it going to look when it get printed out.
\pause
\item It makes very simple to handle equations, figures, bibliography and index.

\begin{itemize}
\item Use vector images(for eg. \textsf{*.ps} and \textsf{*.pdf}) rather than raster images(for eg. \textsf{*.png}) so that, the resolution is in good quality.\\
\pause
\vspace{0.2cm}
{\small \bfseries \underline{Vector images} are created in drawing programs. This program uses points connected with curves or straight lines, like connect-the-dots. The advantage of using this images is that it is resolution independent.\\
But, \underline{Raster or bitmapped images} uses pixels to define images.}
\pause
\item Do not use spaces while naming the images.
\pause
\item Choose file names that is specific and descriptive.
\pause
\item Put all the images in one folder.

\frametitle{Bibliography: Bibtex}
We'll create bibliography using Bibtex rather than thebibliography environment({\color{brown}\href{https://www.sharelatex.com/learn/Bibliography_management_with_bibtex}{if you like, click how!}}). Here are the following steps:
\begin{itemize}
\item Create a new file in the texmaker.
\item Click {\color{blue}Bibliography} menu Then, {\color{blue}Bibtex}.
\item Choose which type of document you want to cite. For eg: \textquotedblleft Article in Journal\textquotedblright.
\item Then, you will see like:
\end{itemize}
\end{frame}
\begin{frame}[fragile]
\frametitle{contd.}
\begin{lstlisting}
@Article{*, % this line * means label for citation.
author = {*},
title = {*},
journal = {*},
year = {*},
OPTkey = {*}, % OPT means optional
OPTvolume = {*}, %if you want to put volume then,
%remove OPT and make it volume = {*}
OPTnumber = {*}, %if you donot need these just remove it.
OPTpages = {*},
OPTmonth = {*}, %never forget "comma"
OPTnote = {*},
OPTannote = {*}
}
\end{lstlisting}
\end{frame}
\begin{frame}[fragile]

\end{frame}
\begin{frame}[fragile]
\frametitle{contd.}
\begin{itemize}
\item Save it as {\color{blue}?bibfile.bib} and should be within the same folder of your document's tex file.
\end{itemize}
\begin{lstlisting}
\begin{document}
...\cite{cdt} %Creates citation!
...\citep{cdt} %creates citation with parenthesis!

\subsection{Extra Packages}
\begin{frame}{How to install extra packages}
\textbf{\underline{Error}}: \textquotedblleft class file\textquotedblright or \textquotedblleft package file\textquotedblright not found.\\
\textbf{\underline{Means}}: Package needs to be installed.\\
\textbf{\underline{Steps}}:\\
\vspace{0.2cm}
\textbf{[1] \underline{For linux users*}}:
\begin{itemize}
\item First, you need to have \textsf{texlive-full} installed.
\item Know which file is missing by seeing in Message/Log of Texmaker.
\item Open the terminal.
\item Type: \textsf{cd /usr/share/texlive/texmf-dist/tex/latex}
\item Make a directory to make your files organize as by typing: \textsf{sudo mkdir ?package\_dir}
\item Download \& extract the package from \href{https://www.ctan.org/}{Comprehensive \TeX\hspace{0.2cm} Archive Network(CTAN)} or any resources.
\end{itemize}
\end{frame}
\begin{frame}{contd.}
\begin{itemize}
\item Copy the file, by typing:\\{\footnotesize \textsf{sudo cp /home/?username/Downloads/?package/?.sty ./?package\_dir}}\\
{\color{red}Don't copy \textsf{*.bst}. The bst file will go in the /bibtex/bst directory. And, it should be known that other files(i.e. \textsf{*.tex, *.pdf, *.dvi}) are likely documentation for the package.}
\item Update the filename database using the texhash command by typing:\textsf{ sudo texhash}\\
{\color{blue}Messages about texhash updating, then done.}
\vspace{0.4cm}
\pause
{\color{purple}\underline{Motivation}: I just wanted to teach you some commands in linux terminal. \dLaughey}
\end{itemize}
\end{frame}
\begin{frame}{contd.}
\textbf{[*] \underline{Simplest way}}:
\begin{itemize}
\item Know which package is missing from the Message/Log of Texmaker.
\item Download the required package and extract it.
\item Put the \textsf{?.sty} file inside the folder where your document source code \textsf{?.tex} is in!
\item Click Quick build in the texmaker!
\item It will automatically install that package in the texlive package directory.
{\color{blue}I haven't yet got issue\footnote{If you find issue then, shot me an email at \texttt{dphysicslog@gmail.com} and we will together solve that problem.} while following this step! \dSmiley}
\end{itemize}
\end{frame}
\begin{frame}{contd.}
\textbf{[2] \underline{For Windows users}}:
\begin{itemize}
\item Click \textit{Windows key} and search \textit{miktex package manager}.
\item Open it and search the package you want! \\
{\color{red} Need internet connection!}
\item Install it! \\
\pause
{\color{blue}But, if you have package downloaded then, follow the below steps:}\\
\pause
\item Copy the package file and paste to the path \textsf{Local disk C $\rightarrow$ Program Files $\rightarrow$ MiKTeX 2.9 $\rightarrow$ tex $\rightarrow$ latex $\rightarrow$ ?package\_dir (create a folder)$\rightarrow$ paste it here! }
\item Then, click \textit{Windows key} and search \textit{miktex settings(Admin)}.
\item Open it and click \textit{Refresh FNDB\footnote{FNDB means File Name Database}} then, click \textit{OK}.\\
