In this post I will show how to change the definition of the page style (say empty) if you are using fancyhdr package. Just add the following type of code in the preamble of the document (before the \begin{document} ): \fancypagestyle{empty}{% \fancyhf{} % clear all header and footer fields \fancyfoot[R]{\bfseries \em \thepage } % except the center \renewcommand{\headrulewidth}{0pt} \renewcommand{\footrulewidth}{1pt}} Here you can use all kind of fancyhdr package command to specify you options and formatting. Hope this will be helpful. Cheers APaul

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.

Okay, here is what I exactly wanted to do; I have to work on several computer and laptop. So I wanted to create local texmf directory in some cloud service folder (like dropbox) and then sync them across the different computer. But the problem is the local texmf directory in TexLive in Ubuntu is /usr/local/texlive/texmf-local So I have created a symbolic link of the texmf directory of dropbox inside the /usr/local/texlive/texmf-local/tex/latex/ . It is working fine. Hope this will work for you also. Cheers APaul

Suppose you have installed foo.exe thorough wine. But when you lunching it the unity side panel showing wine icon instead of foo icon. To solve this go to folder ~./local/share/applications/   Open foo.desktop in your favorite text editor. Then append the line StartupWMClass=foo.exe in the file (make sure to change foo to your actual application name) and save it. Now lunch the application it should show proper icon.
