तेरे आने का शुक्रिया !

गिराते नहीं अगर तुम, तो मैं क्यों बनाता ये मंजिलें,
ऐ वक्त तेरा चोट देते जाने का शुक्रिया;

भुझाते नहीं अगर तुम, तो मैं क्यों जलाता ये दीये,
आँधियों मेरी महफ़िल में आने का शुक्रिया;

भीगाते नही अगर तुम, तो मैं क्यों बनाता ये छतरियाँ,
बादलों मेरे घर में बरसने का शुक्रिया;

आती नहीं अगर तुम, तो मैं क्यों बनाता ये सीढियां,
दीवारों मेरी राह में आने का शुक्रिया;

टूटते नहीं अगर तुम, तो मैं क्यों सजाता ये शमां,
ऐ ख्वाब मेरी जिंदगी में आने का शुक्रिया!

Page Rank - How Search Engines Rank Web Pages?

Search for anything using your favorite crawler-based search engine. Nearly instantly, the search engine will sort through the millions of pages it knows about and present you with ones that match your topic. The matches will even be ranked, so that the most relevant ones come first.

Of course, the search engines don't always get it right. Non-relevant pages make it through, and sometimes it may take a little more digging to find what you are looking for. But, by and large, search engines do an amazing job.

As WebCrawler founder Brian Pinkerton puts it, "Imagine walking up to a librarian and saying, 'travel.' They’re going to look at you with a blank face."

OK -- a librarian's not really going to stare at you with a vacant expression. Instead, they're going to ask you questions to better understand what you are looking for.

Unfortunately, search engines don't have the ability to ask a few questions to focus your search, as a librarian can. They also can't rely on judgment and past experience to rank web pages, in the way humans can.

So, how do crawler-based search engines go about determining relevancy, when confronted with hundreds of millions of web pages to sort through? They follow a set of rules, known as an algorithm. Exactly how a particular search engine's algorithm works is a closely-kept trade secret. However, all major search engines follow the general rules below.

Location, Location, Location...and Frequency

One of the the main rules in a ranking algorithm involves the location and frequency of keywords on a web page. Call it the location/frequency method, for short.

Remember the librarian mentioned above? They need to find books to match your request of "travel," so it makes sense that they first look at books with travel in the title. Search engines operate the same way. Pages with the search terms appearing in the HTML title tag are often assumed to be more relevant than others to the topic.

Search engines will also check to see if the search keywords appear near the top of a web page, such as in the headline or in the first few paragraphs of text. They assume that any page relevant to the topic will mention those words right from the beginning.

Frequency is the other major factor in how search engines determine relevancy. A search engine will analyze how often keywords appear in relation to other words in a web page. Those with a higher frequency are often deemed more relevant than other web pages.

Spice In The Recipe

Now it's time to qualify the location/frequency method described above. All the major search engines follow it to some degree, in the same way cooks may follow a standard chili recipe. But cooks like to add their own secret ingredients. In the same way, search engines add spice to the location/frequency method. Nobody does it exactly the same, which is one reason why the same search on different search engines produces different results.

To begin with, some search engines index more web pages than others. Some search engines also index web pages more often than others. The result is that no search engine has the exact same collection of web pages to search through. That naturally produces differences, when comparing their results.

Search engines may also penalize pages or exclude them from the index, if they detect search engine "spamming." An example is when a word is repeated hundreds of times on a page, to increase the frequency and propel the page higher in the listings. Search engines watch for common spamming methods in a variety of ways, including following up on complaints from their users.

Off The Page Factors

Crawler-based search engines have plenty of experience now with webmasters who constantly rewrite their web pages in an attempt to gain better rankings. Some sophisticated webmasters may even go to great lengths to "reverse engineer" the location/frequency systems used by a particular search engine. Because of this, all major search engines now also make use of "off the page" ranking criteria.

Off the page factors are those that a webmasters cannot easily influence. Chief among these is link analysis. By analyzing how pages link to each other, a search engine can both determine what a page is about and whether that page is deemed to be "important" and thus deserving of a ranking boost. In addition, sophisticated techniques are used to screen out attempts by webmasters to build "artificial" links designed to boost their rankings.

Another off the page factor is clickthrough measurement. In short, this means that a search engine may watch what results someone selects for a particular search, then eventually drop high-ranking pages that aren't attracting clicks, while promoting lower-ranking pages that do pull in visitors. As with link analysis, systems are used to compensate for artificial links generated by eager webmasters.

Enjoy the coffee...

A group of alumni, highly established in their careers, got together to visit their old university professor.

Conversation soon turned into complaints about stress in work and life . Offering his guests coffee, the professor went to the kitchen and returned with a large pot of coffee and an assortment of cups--porcelain, plastic, glass, crystal; some plain looking, some expensive, some exquisite --telling them to help themselves to the coffee.

When all the students had a cup of coffee in hand, the professor said: "If you noticed, all the nice looking expensive cups were taken up, leaving behind the plain and cheap ones. While it is but normal for you to want only the best for yourselves, that is the source of your problems and stress.

"What all of you really wanted was coffee, not the cup, but you consciously went for the best cups and were eyeing each other's cups.



Now consider this:
Life is the coffee, and the jobs, money and position in society are the cups.


They are just tools to hold and contain Life, and do not change the quality of Life. Sometimes, by concentrating only on the cup, we fail to enjoy the coffee God has provided .

"So, don't let the cups drive you .... enjoy the coffee instead ."

How to remove yahoo messenger worm ?

Promblem:

If your yahoo messenger is affected by this worm it will send the nsl-school.org url (and other different urls) to all of your friend list in yahoo messenger using your ID . So with in few hours many of your friends will get infected with it if they click on any of these links.

I don't know the actual target of the idiot who created it. May be to advertise his site or to steal very imp data from your computer. I resolved the problem manually from 2 infected PC's. Just go through the below steps carefully.

What are those links ?

Nsl-school.org and other (Do not open this url in your browser).

After effects ?

1: It sets your default IE page to nsl-school.org, you can’t even change it back to other page. If you open IE from your comp some malicious code will automatically executed into your computer.

2: It will disables the Task manager / reg edit. So you can’t kill the malicious processes anymore.

3: Files that are gonaa installed by this virus are svhost.exe , svhost32.exe , internat.exe, enet.exe.

you can find these files in windows/ & temp/ directories.

4: It may send the secured & protected information to attacker.


Manual Removal:

1: Close the IE browser. Log out messenger / Remove Internet Cable.

2: To enable Regedit

Click Start, Run and type this command exactly as given below: (better - Copy and paste)

REG add HKCU\Software\Microsoft\Windows\CurrentVersion\Policies\System /v DisableRegistryTools /t REG_DWORD /d 0 /f

3: To enable task manager : (To kill the process we need to enable task manager)

Click Start, Run and type this command exactly as given below: (better - Copy and paste)

REG add HKCU\Software\Microsoft\Windows\CurrentVersion\Policies\System /v DisableTaskMgr /t REG_DWORD /d 0 /f

4: Now we need to change the default page of IE though regedit.

Start>Run>Regedit

From the below locations in Regedit chage your default home page to google.com or other.

HKEY_CURRENT_USER\SOFTWARE\Microsoft\Internet Explorer\Main

HKEY_ LOCAL_MACHINE\SOFTWARE\Microsoft\Internet Explorer\Main

HKEY_USERS\Default\Software\Microsoft\Internet Explorer\Main

Just replace the attacker site with google.com or set it to blank page.

5: Now we need to kill the process from back end. Press Ctrl + Alt + Del

Kill the process svhost32.exe . ( may be more than one process is running.. check properly)

6: Delete svhost32.exe , svhost.exe files from Windows/ & temp/ directories. Or just search for svhost in your comp.. delete those files.

7: Go to regedit search for svhost and delete all the results you get.

Start menu > Run > Regedit >

8: Restart the computer. That’s it now you are virus free.
