Latex Special Character/Font problem - latex

I am new to LaTeX, which I am trying to write my thesis with.
Can anybody guide me how to write ? or maybe it is a special font?
Thank you.

It is the calligraphic form of L. You call it as \mathcal{L} inside a math environment.

When in doubt, try http://detexify.kirelabs.org/classify.html.

How to use latex create "Microsoft" in my document?

I was trying to type "Microsoft" with Latex,
the command I used was:
\textsc{Microsoft Office}
But this attempt would be all capital words.
Would anyone provide me with some advice?
Thank you!
Instead of
\textsc{Microsoft Office}
use
\text{Microsoft Office}

Sublime Text 2: How to set up consistent syntax highlighting for Guardfile?

While it is easy enough to set the language for a given (open) file in Sublime Text, I'm wondering if there is any way that I can tell the editor in advance that anything called "Guardfile" should be highlighted like it's Ruby code. Does anyone know how to do this?
The plugins recommended in the comments by Brian both do the job nicely:
ApplySyntax
SyntaxFromFileName
Update:
I couldn't get SyntaxFromFileName to match any of my regex for some reason. On the other hand, DetectSyntax comes with syntax highlight for the Guardfile built in.
Update2:
DetectSyntax has been renamed to ApplySyntax
Putting the following at the top of said file also works
#!/usr/bin/env ruby

Emacs: Using a major-mode's font-locking only for mmm-mode

I've got MMM-mode set up to edit .html.erb files, but indentation does not work in the ruby sections, and all the different electric behaviours of ruby-mode do the wrong thing. I've changed this sub-mode from ruby-moode to fundamental-mode, and it works much better.
I want to still use ruby-mode's font-locking though, is this possible/easy? Any hints on where to start.
Elisp is comfortable to me, but I don't have too much time right now to dig too deeply myself. Hopefully someone will have a snippet?
I see you haven't yet found an answer. Dunno whether it will be better for this, but you might consider using MuMaMo instead of MMM.
To answer the question, you would define a major mode deriving from fundamental-mode, and in its body just copy the font-lock-related lines from the ruby-mode definition body, the ones setting font-lock- variables and also syntax-propertize-function. Naturally , you need to (require 'ruby-mode) somewhere.
But for .html.erb files I can now recommend using mmm-erb, which was not available when this question was asked.

hide an entry from Toc in latex

I would like to know how I can hide a section from the table of contents but without loosing the section number in the body of the document. For example, in this tex file I loose the number for hide, and all the sequences are damaged:
\documentclass{article}
\begin{document}
\tableofcontents
\section{uno}
\section{dos}
\section*{hide}
\section{tres}
\end{document}
I think you are looking for
\section*{hide}
\addtocounter{section}{1}
or make it into a command:
\newcommand{\toclesssection}[1]{\section*{#1}\addtocounter{section}{1}}
EDIT:
Okay, I think I understand what is wanted now (and it makes more sense then the answer I gave). Here is a command that you can use to suppress adding a section, subsection, etc. to the TOC. The idea is to temporarily disable \addcontentsline.
\newcommand{\nocontentsline}[3]{}
\newcommand{\tocless}[2]{\bgroup\let\addcontentsline=\nocontentsline#1{#2}\egroup}
...
\tocless\section{hide}
\tocless\subsection{subhide}
Just wanted to say thanks for Ivans great hint!
(I was just googling for something similar for my customized (Sub)Appendix{} commands:
\newcommand{\nocontentsline}[3]{}
\newcommand{\tocless}[2]{\bgroup\let\addcontentsline=\nocontentsline#1{#2}\egroup}
\newcommand{\Appendix}[1]{
\refstepcounter{section}
\section*{Appendix \thesection:\hspace*{1.5ex} #1}
\addcontentsline{toc}{section}{Appendix \thesection}
}
\newcommand{\SubAppendix}[1]{\tocless\subsection{#1}}
Maybe this is useful for someone else, too...)
have just come here from a similar question. The answer above didn't quite work as it gave some formatting issues, but a similar solution seemed to do the trick

URL latex linebreak

When a URL is over a line and goes onto a second line, the hyperlink only uses the first line. Is there a way to get around this and yet still have the URL on multiple lines?
You should use the url package:
\usepackage{url}
...
\url{http://long.url.com/... .../stuff}
and it will break it for you at an appropriate place.
I suggest using package:
\usepackage{xurl}
This works fine for me on overleaf.
Example:
\url{https://www.tudelft.nl/ewi/over-de-faculteit/afdelingen/intelligent-systems/pattern-recognition-bioinformatics/pattern-recognition-laboratory/data-and-software/dd-tools/}
At the preamble, just put \usepackage{breakurl} somewhere after \usepackage{hyperref}. The \burl command is defined and, by default, the package also turns the \url command into a synonym of \burl.
Do it the following way. You are good to go!
\begin{document}
\sloppy
For me only this worked:
\PassOptionsToPackage{hyphens}{url}
\usepackage{hyperref}
and with this code to add line breaks after every normal alphabetic character and with *-~'":
\expandafter\def\expandafter\UrlBreaks\expandafter{\UrlBreaks% save the current one
\do\a\do\b\do\c\do\d\do\e\do\f\do\g\do\h\do\i\do\j%
\do\k\do\l\do\m\do\n\do\o\do\p\do\q\do\r\do\s\do\t%
\do\u\do\v\do\w\do\x\do\y\do\z\do\A\do\B\do\C\do\D%
\do\E\do\F\do\G\do\H\do\I\do\J\do\K\do\L\do\M\do\N%
\do\O\do\P\do\Q\do\R\do\S\do\T\do\U\do\V\do\W\do\X%
\do\Y\do\Z\do\*\do\-\do\~\do\'\do\"\do\-}%
answer complited from this site:
https://tex.stackexchange.com/questions/3033/forcing-linebreaks-in-url/10401
What packages (hyperref,url) and drivers (pdftex, dvips, etc.) are you using? Are you using the breaklinks option to hyperref?
According to the TeX FAQ you might want to try the breakurl package, though it appears you may simply be out of luck in some cases.
What worked best for me (with pdflatex) was
\usepackage[pdftex]{hyperref}
and then just \url{http://stackoverflow.com/} to create URLs. It only broke URLs at . and /, which was okay for my document. Importantly, other approaches I tried created PDFs where only the first line of the URL was a clickable link, and the destination URL was truncated to this portion, which is pretty confusing and bad.
Long URLs that contain underscores (_) in path segments will not be broken when using \PassOptionsToPackage{hyphens}{url}\usepackage{hyperref}. However, I found that I could solve this problem by manually breaking lines in the displayed label using \\\\, like this:
\href{http://www.researchgate.net/profile/Nick\_Brooks2/publication/220012411\_Cultural\_responses\_to\_aridity\_in\_the\_Middle\_Holocene\_and\_increased\_social\_complexity/links/0922b4f398ad68bc96000000.pdf}{http://www.researchgate.net/profile/Nick\_Brooks2/publication/220012411\_\\Cultural\_responses\_to\_aridity\_in\_the\_Middle\_Holocene\_and\_increased\_social\_\\complexity/links/0922b4f398ad68bc96000000.pdf}
This results in URLs that are a bit prettier (IMO) than the use of \usepackage{breakurl} and \burl, as suggested by Debajyoti Mondal, and allows you to display the full URL if you wish.
There is a simple answer. Use \usepackage[hidelinks]{hyperref} before \begin{document}
