Introduction
In this post I will show how to create a simple approval queue in Request Tracker 3.8.
The General queue will be used as the approval queue.
Here are the different entities (groups) we will create:
- Submitters: they can submit new tickets only to the General Queue.
- Approvers: they can approve tickets (move them from the general queue to another queue)
I will also show how to add a new dashlet ("RT at a glance") containing all the tickets the user created ("My issues").

A very good way to reduce page load time on your website is to tell your visitors' browser it can cache some specific files and save a copy on the disk.
This process is done by your web-server which is sending an Expires header and a max-age header during the HTTP response, e.g.:
200 OK
Cache-Control: max-age=604800
Connection: close
Date: Tue, 27 Jul 2010 22:31:03 GMT

Apache2 offers this feature through its mod_expires module. Note that this module is usually disabled by default, meaning your visitors would download all the files over again each time they change the page.

A new version of your operating system just got released and you want to have a fresh new install, or you want to migrate all of your data to another machine. There are so much stuff to backup that you don't even know where to start?
I will try to list the most common stuff (on a web-server) to backup or copy somewhere when you want to do a server migration.

Introduction
I wanted to take screenshots of about 15 Websites, but didn't want to install any plugins as I wouldn't use them often. I saw a lot of how-to's using import from Imagemagick but they capture the whole screen, not clearly what I was looking for.
Using chromium, xwininfo (from X) and import, I made this bash script which captures only the webpage. See below for the Source code.
