AJAX Check Username Availability Tutorial

Submitted by Parsiad on Fri, 9 Jan 2009

In this tutorial, you will learn how to make an AJAX application that checks if a given username is available or not. This is useful for registration forms on websites so that the user is not forced to post all of their data (to the server) in order to find out whether or not the username they have picked is available.

At the time of this article's creation, an example of this functionality in action can be found on the Google Accounts Registration Page.

Turn Off Adobe Updater

Submitted by Parsiad on Sun, 5 Oct 2008

Whenever I am on my Windows box using Photoshop, Adobe Updater will pester me with its willingness to update my out of date Adobe Camera Raw package- something I have yet to and most likely will never use.

Fortunately, turning off Adobe Updater isn't hard.

  1. Navigate to C:\Documents and Settings\[username]\Application Data\Adobe\Updater, where [username] is your username.
  2. Open the file AdobeUpdaterPrefs.dat in a text editor such as Notepad.
  3. Change <AutoCheck>0</AutoCheck> to <AutoCheck>1</AutoCheck>.
