One of the most challenging montage or masking jobs in the profession of post-production editing is the hair lift. When the model has long flowing hair and the subject needs to change location many post-production artists call in sick. Get it wrong and, just like a bad wig, it shows. Extract filters, Magic Erasers and Tragic Extractors don’t even get us close

Photoshop is probably the cheapest alternative to plastic surgery possible. Unfortunately, Photoshop is only helpful in computer land. In this tutorial, I’ll show you how to do your own plastic surgery with a nose job to up and coming MTV starlet, Ashlee Simpson.

In this article Martin explains how to create a secure PHP login script that will allow safe authentication. Features remember-me function using cookies, validates logins on each request to prevent session stealing.
How Does This Work
This is a short explanation why I have chosen these authentication methods.
Users with shell access to the web server
can scan valid session id’s if the default /tmp directory is used to store the session data.
The protection against this kind of attack is the IP check.
Somebody who has a site (on a shared host with you) can generate valid session for your site.
This is why the checkSession method is used and the session id is recorded in the database.
Somebody may sniff network traffic and catch the cookie.
The IP check should eliminate this problem too.

You must be root (superuser) to add a user. An easy way to remember the syntax of the useradd command in Solaris is to run it with no options. Follow the resulting usage information including the parts that you require. Important options are:
-d home-directory-path
This is the new user’s home directory, typically /export/home/username
-m
make home directory and copy the default skeleton files (these files are located in /etc/skel directory).

Requirements
RedHat Linux (should apply to 7.x and up)
This tutorial covers changing your hostname in RedHat Linux without having to do a reboot for the changes to take effect. I’ve tested this on RedHat 7.3, 9, Fedora Core 3, and CentOS 4.1. It should work for all the versions in between since they all closely follow the same RedHat configuration. What’s the point of this tutorial? Never reboot if you don’t have to and keep your uptime intact.
Make sure you are logged in as root and move to /etc/sysconfig and open the network file in vi.
cd /etc/sysconfig
vi network
Look for the HOSTNAME line and replace it with the new hostname you want to use. In this example I want to replace localhost with redhat9.

These two scripts are very important for the system admin who regularly works with mail servers and somehow forgets to backup his system username and password! Let’s say somehow we lost the usernames and passwords of the mail server. In this case the admin has to manually create all the users and then change the passwords for all the users. Tedious job. Let’s make our life easier.
First create a file which contains all the user name. Something like this:
