Adding Repository Behind Proxy Using add-apt-repository



 
If you are behind proxy then you may have noticed that adding repository is not easy in Ubuntu. Even though $sudo apt-get-update or $sudo apt-get-install kind of command work, $sudo add-apt-repository don't work.
To get rid of this problem you have to add one line at the end of the sudoer's file. Use the following code in terminal.

And then add the following line at the end of the file

It should work now.

Changing caption width in latex

In this post I will discuss how to change the width of the figure caption. You can use the same technique to change the width of the other caption (like table caption). Here I am using the caption package. In caption package you can specify the width while loading the package or latter using \captionsetup command. Syntax of the both command are as following \usepackage[<option>]{caption} and command for captionsetup is \captionsetup[<float type>]{<option>} In the <option> we can use width=0.8\textwidth to specify width of the caption. If we specify that in the time of loading (i.e. when using with \usepackage command) it will affect all the float (like figure, table) but if you specify it in command \usepackage then you can specify float type. Then the specific float type will only be effected. This way you can specify two different width for different float. You can also specify other kind of formatting (like italic text) usi

Subtitle in latex

There is no direct command to define subtitle in latex. But you can define the \subtitle command using titling package. To do this just insert the following code in the preamble of the latex file. \usepackage{titling} \newcommand{\subtitle}[1]{%   \posttitle{%     \par\end{center}     \begin{center}\large#1\end{center}     \vskip0.5em}% } And then you can define subtitle using the following command. \subtitle{Subtitle Here} This will show the subtitle bellow your title when you use \maketitle command. Minimum working example Code \documentclass[10pt,a4paper]{article} \usepackage{lipsum} \usepackage{titling} \newcommand{\subtitle}[1]{% \posttitle{% \par\end{center} \begin{center}\large#1\end{center} \vskip0.1em}}% \title{This is the title of the document} \subtitle{This is subtitle} \author{Apurba Paul} \date{January 08, 2013} \begin{document} \maketitle Body of the document. \lipsum[1] \end{document} Output

Send in Email in Background in Thunderbird

Image
Mozilla Thunderbird is one of the best email client available for Windows, Linux and Mac. Here I will tell how to send email in background in Thunderbird, so that when you send any mail that irritating "sending email" popup will not come out in front of you. First go to Preferences window: In windows: tools>options In linux: Edit>preferences Now go to Advance tab > General   and click on Config Editor Button, When asked click on I'll be careful, I promise button.  Then search for mailnews.sendinBackground and then select it. Then right click and toggle it to true. Now Thunderbird should send your email in background. You may need to restart the Thunderbird. Cheers A.Paul
