What

A lot of times you are developing a web application on your own laptop or home computer and would like to demo it to the public. Most of those times you are behind a router/firewall and you don't have a public IP address. Instead of configuring routers (often not possible), this solution gives you a public URL that's reverse tunnelled via ssh to your laptop.

Because of the relaxation of the sshd setup, it's best used on a dedicated virtual machine just for this (an Amazon micro instance for example).

Here is a simple jQuery plugin to make a table header fixed on top when window is scrolled.
Using the code from twitter bootstrap documentation page, this code is customized for table header.

Create the table with following layout -
<table class="table-fixed-header">
  <thead class="header">
    <tr>
      <th>Column 1</th>
      <th>Column 2</th>
      <th>Column 3</th>

Semicolon

I use it. If you don't, read these:

• twbs/bootstrap#3057

You can still ignore semicolons, but know that ASI is a syntactic error correction procedure,
