If you want to install new version of ubuntu !

New version of Ubuntu comes on every 6 month with most recent version of software and with, up to some extend, new look. If we don't want to continue with the old version of software and if bored with same look we want install the new version. If you want to upgrade your system then it is ok. But if you want a clean installation then you have to install all your required software and you have to do all setting ones again. This is very tedious job. Here are some tricks to simplify the job.

First you can generate the list of installed software by using this command,
dpkg --get-selections > installed-software
This command will create a text file name installed-software. You can edit this file and if you want remove some software by simply deleting the line containing the name of the software.

Now when you are installing Ubuntu do not format the home folder. This folder actually contain all the settings of the software. And when you re install the software, in most cases, you will get back the setting. Like in the case of Firefox or Chromium.

Now after installation is complete first install dselect by using the command
sudo apt-get install dselect

Now run the command
sudo dpkg --set-selections < installed-software
And then
sudo dselect
This will install all software listed in the file one by one. And you will get back all software.

** Since there are some problem in installing flash-plugin-installer and ttf-mscorefont-installer, I recommend to remove this name from the file and use other method to install them. You try this and this process.

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

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
