"could not get lock /var/lib/apt/lists/lock" problem

Some time when we run sudo apt-get update command we see the following error message:

sudo apt-get update && sudo apt-get upgrade
 Could not get lock /var/lib/apt/lists/lock - open (11: Resource temporarily unavailable)

One possible reason for this error is that you are probably running synaptic package manager or some installation is still going on on software manager or some where some installation or update or up-gradation is going on in system.
But some time you find that nothing is going on but it still showing same problem. Then you can solve the problem using following command

sudo rm /var/lib/apt/lists/* -vf 
sudo apt-get update && sudo apt-get upgrade

Now your update should start properly.

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
