Simple website redirect with perl

For when you're too lazy to fiddle with mod_rewrite, you can use a simple Perl script to redirect file a.pl to b.pl.

Upload a file a.pl with the following content:

chmod a.pl with the right permissions - and, of course, make sure, Perl is supported.

Latex: Centering table larger than textwidth

Usually, you can center tables with \center. But when the table is longer than the \textwidth, it will be align with the left side margin. You can temporarily adjust the textwidth.

% allows for temporary adjustment of side margins
\usepackage{chngpage}

\begin{table}
    \begin{adjustwidth}{-.5in}{-.5in} 
        \begin{center}
        \begin{tabular}{|c|}
            \hline
And here comes a very long line. And here comes a very long line. And here comes a very long line.  \\
            \hline
        \end{tabular}

        \caption{This Table is longer than the text width. And its caption is really long, too. This Table is longer than the text width. And its caption is really long, too. This Table is longer than the text width. And its caption is really long, too. This Table is longer than the text width. }
        \label{myTable}
        \end{center}
    \end{adjustwidth}
\end{table}

Uploading a file with JQuery

You can easily submit data in an html form via jQuery's $.post. But you need to do a little more to upload a file. I suggest the jQuery Form Plugin.

Here is the HTML form:
<html> <head> <title>Title</title> </head> <body> <form action="/test.cgi" enctype="multipart/form-data" method="post"> <input name="myFile" type="file" /> <div id="results"> </div> </form> </body> </html>
This is the Javascript file myFrom.js:
$(document).ready(function() { $('form').ajaxForm( { beforeSubmit: function() { $('#results').html('Submitting...'); }, success: function(data) { var $out = $('#results'); $out.html('Your results:'); $out.append('<div><pre>'+ data +'</pre></div>'); } …

Highlighting paragraphs in Latex

When revising a document, I often want to highlight my changes, so my collaborators can easily see what I changed.

\underline works for single words, but it puts everything in a horizontal box and long text isn't wrapped anymore.

Instead, I use the package soul and \ul to underline.
\usepackage{soul}
Or you can highlight text using \hl. This will underline the text unless you use the color package, then it turns into typical marker-highlight.
\usepackage{color}
