Google Provides Hack For Google Desktop In Google Deskbar.
Google designed the Deskbar with Google Desktop and similar products in mind, because it provided an easy hack to work the Deskbar with Desktop. It's rare Google actually gives this sort of advice themselves, but good for them. Simply:

1. Go to Google and click on the Desktop tab.
2. Copy your URL, which should look like this: http://012.3.4.5:4664/&s=6789012345&q=.
3. Go to the Deskbar and click Options.
4. Go to Customized Searches, click Add, paste your URL in the URL box, but add {1}
   (it'll look like:http://012.3.4.5:4664/&s=6789012345&q={1}) and name it Google Desktop Search.
5. That's it, unless you want to fiddle with the options more.

Google will send you email alerts when specific items are mentioned in the news or found on web sites. I have several alerts running. For example, I like to know when any Microsoft MVPs are mentioned on the web. So I have both a news and a web alert set for "microsoft" "mvp." Whenever new info is found, I get an email about it and a link to that information.

Toogle is a Text version of Googles Image Search. It will fetch the first image on google image search result page and convert the image into a text layout. It seems that they have developed a software that will understand the colour shades used in the image and apply the same colour shade at the specific pixel point! Still in the beta stage, looks promising.

The Gmail Notifier is a downloadable Windows application that alerts you when you have new Gmail messages. It displays an icon in your system tray to let you know if you have unread Gmail messages, and shows you their subjects, senders and snippets, all without your having to open a web browser. To use the Gmail Notifier, you need Windows 2000, Windows XP, or a more recent version of Windows.

Recently I was asked to find good resume templates for word. I googled "resume filetype:dot" (without quotes) and found Word templates. You can preview the templates before downloading it to your computer. Choose "View as HTML" link next to search result.

You can now import contacts into Gmail. Just open the "Contacts" window and click on "Import Contacts". You can then provide Gmail with a CSV (Comma Separated Values) text file containing your contacts. Create a CSV file from Outlook, Outlook Express, Yahoo and Orkut. AOL and Hotmail are specifically excluded as they don't provide CSV export.

If you want to show off your Google PageRank (and always have it visible to check yourself), you can now use the French My.Rank.Online service. Just include the following HTML snippet in your page:
(a href="http://my.rank.online.fr")
(img src="http://my.rank.online.fr/pagerank.php" alt="[PageRank]" style="border: 0; width: 44px; height: 15px;" /)(/a)

If you want to know when the Googlebot indexes your page, you can insert the following PHP code at the beginning:

(?
$email = "yourname@example.com";
if( eregi("googlebot", $_SERVER['HTTP_USER_AGENT']) )
{
mail($email, "Googlebot Alert",
"Google just indexed your following page: " .
$_SERVER['REQUEST_URI']);
}
?)

(You need to replace the ( with opening tag and email address above with yours.)
