How to downgrade software if you have used ppa to upgrade it

In this blog I will tell you how to downgrade some software to Ubuntu's default version if you have upgraded that software using ppa. Many times we want to upgrade some software to its newest version. But Ubuntu does not provide update for all software except for some critical bug fixes or security update. But almost all software maintain there ppa for Ubuntu so that user can get the latest version of that software. But some time you may fill that you should not have upgraded that software to newest version as that is not properly integrated with Ubuntu. So you want to downgrade it. Here I will tell you how you can do that.

Now you can purge the ppa using the following command

Which will automatically downgrade the software to default version of Ubuntu.

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

Image
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

Placing float (table or figure) at the top of the page in otherwise empty page in LaTeX

In latex if a table is going to any empty page (page with only that table and no other text), the table is always aligned vertically centre. And that does not look good always. Even the float place holder like [t] or [ht] or [t!] kind of things does not work. But there is a work around, just paste the following code at the preamble of the document (before \begin{document} ); \makeatletter \setlength\@fptop{0\p@} \makeatother Hope this will solve the problem.
