Google uses a gzip compression for transfer of web pages.That means the data which is to be transferred is compressed by gzip compression and then sent to the user.The browser decompress the gzip data and show to the user as usual data.But if the browser dont support gzip ? Yeah , Google Verify before the gzip compression that the browser supports gzip compression or not else it will send data or html in normal way.

How much is the efficiency of this system ?

I have done some experiments on gzip compression.I made two php files one supporting gzip and other not.The duration of loading of php file without gzip compression was ~128 ms [It was hosted on local host] and when I clicked on php file with gzip compression , I was amazed to see the results it was about ~ 56 ms .So this really worth.

How is this technically possible ?

It is very easy with PHP , I will post the code which is to be pasted above the php file you want to compress.

<?php
ob_start(“ob_gzhandler”);
?>

This will speed up your loading speed of a web page.But this code is incomplete without validation that the browser supports gzip or not .

Browser sends the header to the server named “Accept-Encoding” , If the gzip is listed in that means you can use it else normal encoding will used which is by default.

<?php

if(preg_match(‘/gzip/’,$_SERVER['Accept-Encoding']))

{

ob_start(‘ob_gzhandler’);

}

?>

So this way you will able to add this system to your PHP pages , But what about others like asp , cgi etc.Using same logic you can add in other programming language also as the gzip and Accept-Encoding will be the common terms throughout the web .

Here are some of the most dangerous computer viruses in history:

Jerusalem – 1988

This is one of the first MS-DOS viruses in history that caused enormous destructions, affecting many countries, universities and company worldwide. On Friday 13, 1988 the computer virus managed to infect a number of institutions in Europe, America and the Middle East. The name was given to the virus after one of the first places that got “acquainted” with it – the Jerusalem University.

Along with a number of other computer viruses, including “Cascade”, “Stoned”, “Vienna” the Jerusalem virus managed to infect thousands of computers while still remaining unnoticed. Back then the anti-virus programs were not as advanced as they are today and a lot of users had little belief of the existence of computer viruses.

Morris (a.k.a. Internet Worm) – November 1988

This computer virus infected over 6,000 computer systems in the United States, including the famous NASA research Institute, which for some time remained completely paralyzed. Due to erratic code, the worm managed to send millions of copies of itself to different network computers, being able to entirely paralyze all network resources. The damages caused by the Morris computer virus were estimated at $96 millions.

To be able to spread the computer virus used errors in such operating systems as Unix for VAX and Sun Microsystems. There were a number of other interesting ideas used by the virus – for example it could pick user passwords.

Solar Sunrise – 1998

A decade later the situation didn’t change, it might have gotten even got worse. Using a computer virus, hackers, in 1998, penetrated and took control of over 500 computers systems that belonged to the army, government and private sector of the United States. The whole situation was dubbed Solar Sunrise after the popular vulnerabilities in computers that run on the operating system called Sun Solaris. Initially it was believed that the attacks were planed by the operatives in Iraq. It was later revealed that the incidents represented the work of two American teenagers from California. After the attacks, the Defense Department took drastic actions to prevent future incidents of this kind.

Melissa – 1999

For the first time computers got acknowledged with Melissa computer virus on March 26, 1999, when the virus shut down Internet mail system, which got blocked with e-mails infected by the worm. It is worth mentioning that at first Melissa was not meant to cause any harm, but after it overloaded servers the virus led to unpredictable problems. For the first time it spread in the Usenet discussion group alt.sex. Melissa was hidden within a file called “List.DiC”, which featured passwords that served as keys to unlocking 80 pornographic websites. The original form of the virus was sent through e-mail to different users.

Melissa computer virus was developed by David L. Smith in Aberdeen Township, New Jersey. Its name comes from a lap dancer that the programmer got acknowledged with while in Florida. After being caught, the creator of the virus was sentenced to 20 months in federal prison and ordered to pay a fine of $5,000. The arrest represented a collaboration of FBI, New Jersey State Police and Monmouth Internet.

Melissa had the ability to multiply on Microsoft Word 97 and Word 2000, as well as Microsoft Excel 97, 2000 and 2003. In addition, the virus had the ability to mass-mail itself from Microsoft Outlook 97 or Outlook 98.

I Love You – May 2000

Using a similar method as the Melissa, the computer virus dubbed “I Love You” managed to infect millions of computers around the world in just one night. Just like Melissa this computer virus sent passwords and usernames, which were stored on the attacked computers, back to the developer of the virus. After authorities traced the virus they found that a young Filipino student was behind the attack. The young man was released due to the fact that the Philippines did not have any law that would prevent hacking and spreading malware. This situation served as one of the premises for creating the European Union’s global Cybercrime Treaty.

The Code Red worm – July 2001
This 21st century computer virus managed to penetrate tens of thousands of systems that ran Microsoft Windows NT as well as Windows 2000 server software. The damages caused by the Code Red computer virus were estimated at a total of $2 billion. Core Red was developed to use the power of all computers it infected against the official website of the White House at a predetermined date. In collaboration with different virus hunters and tech firms, the White House managed to decipher the code of the Code Red virus and stop traffic as the malware started its attacks.

Nimda – 2001

Shortly after the September 11 tragedy this computer virus infected hundreds of thousands of computers worldwide. Nimda was considered to be one of the most complicated viruses, having up to 5 different methods of infecting computers systems and duplicating itself.

Downadup – 2009

The latest and most dangerous virus is the “downadup” worm, which was also called “Conficker”. The computer security company F-Secure stated that the computer virus has infected 3.5 million computers worldwide. This malicious program was able to spread using a patched Windows flaw. Downadup was successful in spreading across the Web due to the fact that it used a flaw that Microsoft patched in October in order to distantly compromise computers that ran unpatched versions of Microsoft’s operating system. But the greatest power of the worm is believed to be the ability of computers, infected with the worm, to download destructive code from a random drop point. F-Secure stated that three of the most affected countries were China, Brazil and Russia.

US-CERT on Tuesday warned about vulnerability in the new Firefox 3.5 browser that could allow a remote attacker to execute malicious code.Proof-of-concept exploit code was posted Monday on Milw0rm.com, an exploit code aggregation site, so it’s likely that the vulnerability is being actively exploited.

The vulnerability, discovered by Simon Berry-Byrne, is related to the way Firefox 3.5 processes JavaScript code.Mozilla has acknowledged the vulnerability and has a fix that’s being tested. “The vulnerability can be exploited by an attacker who tricks a victim into viewing a malicious Web page containing the exploit code,” the company said on its security blog. “The vulnerability can be mitigated by disabling the JIT in the JavaScript engine.

To do this:

1) Enter about:config in the browser’s location bar.

2) Type jit in the Filter box at the top of the config editor.

3) Double-click the line containing javascript.options.jit.content setting the value to false.

As an alternative, the NoScript plug-in, which disables all JavaScript in the browser, should also offer protection.

Secunia, a computer security company based in Denmark, rates the vulnerability “highly critical” and notes that older versions of Firefox may be affected as well.

F-Secure, a computer security company based in Finland, said in a blog post that its Exploit Shield security software blocks the exploit.

In an interview on Monday about a bug in Google’s Chrome browser, Robert “RSnake” Hansen, CEO of SecTheory, a computer security consulting firm, criticized Firefox’s security process as being less rigorous than Microsoft (NSDQ: MSFT)’s. “For the most part, it’s just a bunch of random dudes who are contributing to it,” he said.

Nevertheless, Hansen said that Firefox, rather than Internet Explorer, was his browser of choice because it was better for hacking.

Johnathan Nightingale, whose business card says “human shield” — he manages the front-end team for Firefox and security issues — says he’s proud of the work Mozilla does and that he can’t compare Mozilla’s efforts to Microsoft’s because Microsoft’s security process isn’t open.

He notes that Mozilla devotes significant resources to security and that the company’s security team has been growing. He welcomes those who want to contribute to Mozilla to make it more secure.

It is always a head ache when we search for our information in google and when google send us to the forums  or any text oriented website where registration is compulsory.But I have found out a way to cheat the registration system.When google  can cache there information without registration than why not us :p .There are setting in the forum script that if the visitor is google bot they wont ask for registration and allow it to crawl through out the  pages,as it will help them to gain traffic.If we act like a google bot we can also get such privileges.

Google began life in January 1996, not as an internet search engine and online advertising corporation as it was destined to become, but as the thesis project of Larry Page, later joined in his endeavors by Sergey Brin, both PhD students at Stanford University, California.

The name ‘Google’ itself was derived from a misspelling of ‘googol’ (ten raised to the power of a hundred) but the original name for the search engine was BackRub’, paying homage to the theory of the importance of back linking, or citation, which was the cornerstone of the project.

Page had hypothesized that if he could find a way to count and analyze the value of each back link on the web then a search engine using this qualitative data would necessarily yield more useful results than other engines which just counted keywords, Google’s mission statement, to organize the world’s information and make it universally accessible and useful,’ reflects this original, core aim.

The project was highly complex and ambitious and these factors drew in Sergey Brin who began working on the project with Page. They created an algorithm that encompassed the number of links to a particular site and also the number of links into each of the sites linked. This algorithm was named PageRank’, after Page.

The verb ‘Google,’ was added to the Merriam Webster Collegiate Dictionary and the Oxford English Dictionary in 2006 and Google has become integrated into society as a noun in its own right. The practice of searching for information on the web has come to be referred to simply as ‘Googling’, a tribute to the success and effectiveness of the project’s aims.

Google has spawned various internet practices such as to Google yourself’, a process of typing your own name into Google and seeing what comes up, on certain forums and on-line communities some innovative people post the names of friends they have lost contact with in the hope that these friends will Google themselves, find the post and make contact.

Another internet term that has been spawned is Google bomb’ (also known as a link bomb’), this came about in the realms of net slang to describe the practice of attempting to get a large number of sites to link to a web-site using specific terms, usually with mischievous intentions, the result of such bombs can for example be that a derogatory word or phrase entered into Google will bring up a specific person’s homepage.

Google stated in early 2007 via their official bog that they had created ‘an algorithm that minimizes the impact of many Google bombs,’ but whilst Google have publicly stated that they do not condone the practice of Google bombing it’s likely that the extent to which their project has become so integral to the web and it’s users overrides any annoyances that come with such broad territory.
TRIVIA: Google’s headquarters in Mountain View, California is known as “the Googleplex”, this is a further play on googol’ as googolplex means equivalent to ten raised to the power of a googol.

And take a one domain for you ,or even more :p.Yeah offcourse you dont have full control on domain They have there own flash based webbuilder you need to build content oriented website throw that and you get email access too,its just similar to chi.mp i grabbed chetan.ws , It includes affilimate programmes also so you can also earn $ aswell as get free domain .

Every PC in China could be at risk of being taken over by malicious hackers because of flaws in compulsory government software.

The potential faults were brought to light by Chinese computer experts who said the flaw could lead to a “large-scale disaster”.

The Chinese government has mandated that all computers in the country must have the screening software installed.

It is intended to filter out offensive material from the net.

The Chinese government said that the Green Dam Youth Escort software, as it is known, was intended to push forward the “healthy development of the internet” and “effectively manage harmful material for the public and prevent it from being spread.”

“We found a series of software flaws,” explained Isaac Mao, a blogger and social entrepreneur in China, as well as a research fellow at Harvard University’s Berkman Center for Internet and Society.

For example, he said, tests had shown that communications between the software and the servers at the company that developed the program were unencrypted.

Mr Mao told BBC News that this could allow hackers to “steal people’s private information” or “place malicious script” on computers in the network to “affect [a] large scale disaster.”

For example, a hacker could use malicious code to take control of PCs using the software.

“Then you have every computer in China potentially as part of a botnet,” Colin Maclay, also of Harvard, told BBC News.

A botnet is the name given to a network of hijacked computers that can then be used to pump out spam or launch concerted attacks on commercial or government websites.

No one from Jinhui Computer System Engineering, the company that developed Green Dam, was available for comment.

‘Naked pig’

The software has also caused a backlash amongst privacy experts, academics and some Chinese citizens. It has also raised the scorn of the blogosphere inside the country who feel the system is no match for tech-savvy teenagers.

Every new computer in China will have the software installed

One blogger posted a screenshot of the software purportedly blocking an attempt to visit a porn site using Microsoft’s Internet Explorer.

But, he said, there was no problem accessing the site using the Firefox web browser.

Others have reported that the system only runs on Microsoft Windows, allowing Mac and Linux users to bypass the software.

It is thought that at least 3m computer users have already downloaded the software, opening them up to potential security problems.

Another formal study by the Open Network Initiative into the risks posed by the software is expected soon. However, many people in China who have been forced to use the software are already reporting other problems.

For example, the system reportedly blocks legitimate as well as banned content. For example, it designed to identify the proportion of skin colour in a picture to determine whether it is pornography.

But comments on a bulletin board run by the software company that designed the system, suggest the system does not work perfectly.

Once you’ve got government-mandated software installed on each machine, the software has the keys to the kingdom “ Professor Jonathan Zittrain

“I went on the internet to check out some animal photos. A lovely little naked pig was sent onto the black list. Pitiful little pig!,” read one comment.

“I was curious, so I looked up some photos of naked African women. Oh, they were not censored!”

Another message read: “We were ordered to install the software. So I have to come to this website and curse. After we installed the software, many normal websites are banned.”

The forum was taken down after it was seemingly flooded with complaints. A message on the site said says it is being “upgraded”.

Mr Mao told BBC News that they believed there was a new guideline from the country’s central propaganda department “to comb all media and online forums to block critics and discussion over the issue.”

Firewall flaw

The government may be keen to shut down discussion to quell rumours that the system could be used to monitor its citizens.

“Once you’ve got government-mandated software installed on each machine, the software has the keys to the kingdom – anything can be logged or affected,” said Professor Jonathan Zittrain, also of Harvard’s Berkman Center.

“While the justification may be pitched as protecting children and mostly concerning pornography, once the architecture is set up it can be used for broader purposes, such as the filtering of political ideas.”

In particular, the system could be used to report citizens’ web habits.

“It creates log file of all of the pages that the users tries to access,” Mr Maclay told BBC News.

“At the moment it’s unclear whether that is reported back, but it could be.”

A twitter user in China claims that the software transmits reports to Jinhui – the maker of the software – when the user tries to access blacklisted websites.

However, Zhang Chenmin, general manager of the developer of Green Dam, told the China Daily newspaper last year: “Our software is simply not capable of spying on internet users, it is only a filter.”

Although many countries around the world routinely block and filter net content, China’s regime is regarded as particularly severe.

“There is no transparency about what they are blocking,” said Mr Maclay.

Free speech campaigners are concerned that the list could be tweaked to suits the government’s aims.

Recently, there has been a web black out across China in advance of the 20th anniversary of the Tiananmen Square massacre.

Website such as Twitter and the photo-sharing site Flickr were blocked in an attempt by the government to prevent online discussion on the subject.

However, some users were able to bypass the filters to distribute pictures and commentary including links to photos of plain-clothes policemen blocking the lenses of foreign journalists with their umbrellas.

The country is able to take action like this because it already has a sophisticated censorship regime, including the so-called Great Firewall of China. However, it is known to have some flaws.

A 2007 study by US researchers showed that the system was much more porous than previously thought.

It found that the technology often failed to block content banned by the Chinese government, allowing web users to browse unencumbered at least some of the time.

Filtering and blocking was “particularly erratic”, they said, when large numbers of people were online in China.

Despite the failures, the researchers said, the idea of the firewall was more effective than the technology at discouraging talk about banned subjects.

This kind of social pressure was also key to another tactic used by the Chinese government to make sure its citizens only use sanitised portions of the web.

In 2007, the government introduced virtual policemen that pop-up onscreen when web surfers visit many of China’s popular website to remind them to stay away from illicit content.

In addition, the government expects internet service providers in China to actively monitor and censor published content, such as blogs.

Experiments have suggested that this approach is hit-and-miss, with some organisations more proactive than others.

However, these systems, combined with the new software, will allow the Chinese government to sanitise the web for most of the 300m of China’s population of 1.3bn have access to the net.

“I think this is intended as a sort of belt-and-braces approach, said Professor Zittrain.

The most notable addition would seem to be the ability to browse themes from within the WordPress Dashboard. With the Theme Browser, you can specify the color you want, how many columns there should be, and fixed or flexible width. You can then select and install themes that match those criteria on-the-fly, without leaving the Dashboard.

WordPress 2.8 also offers a re-designed widgets interface, improved speed, and has fixed a reported 790 bugs.

WordPress 2.8 Highlights

• Theme Browser and Installer
• Ability to add Custom Headers
• New drag-and-drop widgets admin interface and new Widgets API
• New ways to customize dashboard widgets
• Syntax highlighting and function lookup built into plugin and theme editors.
• Configurable Views on Management Pages.
• Faster Loading Admin Pages

Theme Browser and Installer

The earlier versions of WordPress made it much more easier to install and update plugins, WordPress 2.8 adds a feature to allow users to easily install and upgrade themes.

The theme browser provides users with a variety of options to search themes, the options provided are colors, number of columns width, features and more. In addition to that you can also search themes by keywords.

WordPress 2.8 also adds the ability to install themes with a single click, much like it does for plugins, you can also preview the themes without first installing them.

Custom Headers

Many themes come with custom headers that are included by default, changing them would require the users manually editing the theme, or in some cases using the theme options.

However with WordPress 2.8 users can now add their own custom headers, you can upload a image and crop it before applying it as the header image.

The custom headers feature will only work if the theme author has configured the theme to allow this capability, you can read more about the customizing headers feature.

New Drag and Drop Widgets and Widgets API

Widgets play a big role in allowing users to customize their themes without the need to manually edit the theme, WordPress 2.8 has done a huge overhaul of how widgets work, allowing users to easily move widgets between different widget areas with ease.

Users can now also use the same widgets on multiple widget areas, something that was not possible in the earlier versions of WordPress.

Along with the added flexibility WordPress 2.8 also includes a widget API that will make developing widgets much more easier than before.

Customize Dashboard Widgets

The Admin Dashboard in WordPress is a place where you get the most information about tons of things, however earlier versions of WordPress only allowed users to rearrange the widgets.

With WordPress 2.8 users can now specify the number of columns they want to see in the dashboard area, at present users can customize the view up to 4 columns.

Syntax Highlighting for Plugins and Theme editor

If you have ever taken a look the plugin and theme editors in previous versions of WordPress, it has been almost like you are viewing the code in a plain text editor.

However that is about to change in WordPress 2.8, as it adds syntax highlighting which resembles a proper code editor and also a easy way to lookup functions that are used.

Configurable Views on Management Pages

WordPress by default displays a host of information to the users when managing the content or comments, however not all users may find those information useful to them.

WordPress 2.8 allows users to easily configure what information should be displayed by using the Screen options on different management pages.

Faster Loading Admin Pages

The admin pages in WordPress 2.8 load much more faster than the earlier versions thanks to various script compression and concatenation that are used.

I did see a considerable increase in speed when compared to WordPress 2.7.1.

Most people won’t notice this, but emails actually arrive in your inbox with a ‘receipt’, which contains a lot of information about the sender. In order to find the sender’s identity, we only need to retrieve an IP address, but inside the email header we can also find the originating domain, reply-to address and sometimes even the email client, for example Thunderbird.

Why would you want to find out the identity of the sender? Well, you may have heard of shady email scams or emails supposedly from Paypal inviting you to re-enter your personal information. Now, you can determine if an email is truly from the authentic source.

Accessing the email header is different for every email provider or email application, and sometimes, it is even hidden. In most of the cases however, the option to reveal the full header will be somewhere in the area where the subject and sender name are provided.

For example, the Yahoo! Mail header is in the upper right corner of the sender box, which is pointed out in the screenshot above. When you click Show Original, a text file will open in a new tab. This file contains all the necessary headers at the start. They are highlighted in screenshots.

And this is how the full email header appears in Yahoo! Mail:

For Gmail, the header is hidden under ‘Show Original’ – which will show you the complete email in plain text, including the header.

The example below is the header from an email I received in GMail.

In order to find out the IP address of the original sender, we need to look closely at the first half of the header. Somewhere in there, you’ll find a domain name and an IP address. Particularly, take a closer look at the term ‘Received: from’:

The first ‘Received: from’ line gives us the IP address of the server which forwarded the email to my Gmail address.

Received: from smtp110.biz.mail.mud.yahoo.com(smtp110.biz.mail.mud.yahoo.com [68.142.201.179])

If we continue our search, the second ‘Received: from’ line gives us the originating IP address.

Received: from unknown (HELO ?192.168.0.100?) (chaz@68.108.204.242 with plain)

This means that Chaz, located at 68.108.204.242 sent me an email.

The next line will only appear if the email was sent using an email application residing on the sender’s computer, like Thunderbird or Apple Mail. In our case:

X-Mailer: Apple Mail (2.753.1)

If the user sent the email using the web interface, the string would have looked like this:

Received: from [158.143.189.83] by web56706.mail.re3.yahoo.com via HTTP

We have the originating IP address 68.108.204.242 . To find out who’s behind that IP address we need to do a reverse DNS lookup using a web service like DomainTools, the command line or from ‘Network Tools’ in Ubuntu.

In our case, we know that someone called Chaz from Atlanta, using Cox Communications – with an IP address 68.108.204.242, depending on the subnet mask, sent that email.

Alternatively, you could use a tool called Email Trace, that does the whole operation for you after inputing the full email header into the text box. It might not always work, so knowing how to do it the old fashion way might come in handy.

This proves useful if you’re trying to report a spammer to your ISP, find out where a certain person is located at the moment, or help you spot phishing emails. For example, PayPal couldn’t have sent an email from an IP address in China.

If you know other good uses for this procedure, please share it with us in the comments.
