Shocking news about CTRL+C clipboard hacking

Ctrl+C may be the most important work we do everyday. But it's not a very safe thing to do. Read on to know why. What happens when you press Ctrl+C while you are online. We do copy various data by Ctrl + C for pasting elsewhere. This copied data is stored in clipboard and is accessible from the net by a combination of Javascripts and ASP. This is called clipboard hack problem.

Just try this:

1. Copy any text by Ctrl + C

2. Click the Link: Clipboard Hack
(in internet explorer or netscape only)

3. You will see the text you copied was accessed by this web page.

Surprised! I know you are because i was also surprised to see it. Do not keep sensitive data (like passwords, credit card numbers, PIN etc.) in the clipboard while surfing the web. It is extremely easy to extract the text stored in the clipboard to steal your sensitive information. Forward this information to as many friends as you can, to save them from online frauds!

It is true, text you last copied for pasting (copy & paste) can be stolen when you visit web sites using a combination of JavaScript and ASP (or PHP, or CGI) to write your possible sensitive data to a database on another server.

How Cipboard Hack is done?

The Clipboard hack is done by the following Source Code:

How to safeguard yourself from Clipboard Hack Problem?

To avoid clipboard hack problem, do the following:

2. Press custom level.

3. In the security settings, select disable under Allow paste operations via script.

Now the contents of your clipboard are safe.

Interestingly, this hack works only on internet explorer, and not on Mozilla Firefox browser. Please forward this article to as many friends as you can to make them aware of this issue with CTRL+C.

C Program Without a Main Function

How to write a C program without a main function?. Is it possible to do that. Yes there can be a C program without a main function. Here’s the code of the program without a main function…

#include<stdio.h>
#define decode(s,t,u,m,p,e,d) m##s##u##t
#define begin decode(a,n,i,m,a,t,e)</stdio.h>
int begin()
{
printf(" hello ");
}

Does the above program run without the main function? Yes, the above program runs perfectly fine even without a main function. But how, whats the logic behind it? How can we have a C program working without main?
Here we are using preprocessor directive #define with arguments to give an impression that the program runs without main. But in reality it runs with a hidden main function.
The ‘##‘ operator is called the token pasting or token merging operator. That is we can merge two or more characters with it.
A Preprocessor is program which processess the source code before compilation.

Look at the 2nd line of program -
#define decode(s,t,u,m,p,e,d) m##s##u##t

What is the preprocessor doing here. The macro decode(s,t,u,m,p,e,d) is being expanded as “msut” (The ## operator merges m,s,u & t into msut). The logic is when you pass (s,t,u,m,p,e,d) as argument it merges the 4th,1st,3rd & the 2nd characters(tokens).

Now look at the third line of the program -
#define begin decode(a,n,i,m,a,t,e)

Here the preprocessor replaces the macro “begin” with the expansion decode(a,n,i,m,a,t,e). According to the macro definition in the previous line the argument must be expanded so that the 4th,1st,3rd & the 2nd characters must be merged. In the argument (a,n,i,m,a,t,e) 4th,1st,3rd & the 2nd characters are ‘m’,'a’,'i’ & ‘n’.

So the third line “int begin” is replaced by “int main” by the preprocessor before the program is passed on for the compiler. That’s it…

The bottom line is there can never exist a C program without a main function. Here we are just playing a gimmick that makes us beleive the program runs without main function, but actually there exists a hidden main function in the program. Here we are using the proprocessor directive to intelligently replace the word begin” by “main”. In simple words int begin=int main.

How to Change the Logon Screen Background in Windows 7

How would you like to change the logon screen background in Windows 7 so as to give your Windows a customized look and feel? With a small tweak it is possible to customize the Windows 7 logon screen and set your own picture/wallpaper as the background. Changing logon screen background in Windows 7 is as simple as changing your desktop wallpaper. Well here is a step by step instruction to customize the logon screen background.

1. The image you need to set as the background should be a .jpg file and it’s size should not exceed 245KB.

2. The image resolution can be anything of your choice. However I prefer 1440 x 900 or 1024 x 768. You can use any of the photo editing software such as Photoshop to compress and set the resolution for your image. Once you’re done, save this image as backgroundDefault.jpg.

3. You will need to copy this image to

C:\Windows\system32\oobe\info\backgrounds

You will need to create that path if it does not already exist on your computer.

4. Now open the Registry Editor (Start -> Run -> Type regedit) and navigate to the following key

HKLM\Software\Microsoft\Windows\CurrentVersion\Authentication\
LogonUI\Background

If Background does not exist rightclick LogonUI, select New and then Key, and then name it Background. Now locate OEMBackground (listed on the right side). If it does not exist, right-click Background and select New and then DWORD and name it OEMBackground.

5. Double-click on OEMBackground and set the Value Data to 1.

6. Now log-off to see the new logon screen background. If you would like to revert back to the default background, just set the Value Data back to 0.

I hope you like this trick. Just try out and give your feedback!

Apple unveils iPhone 4 with 720p HD Recording

Highly anticipated smartphone brings video calling, 5 megapixel camera and a stunning display

Apple CEO Steve Jobs kick-started the Worldwide Developers Conference 2010 in San Francisco with the announcement of the next generation iPhone model - iPhone 4. After the infamous Gizmodo and Vietnamese iPhone 4 leak, Apple has stuck to its plans and announced the fourth generation iPhone model. Just like the first generation iPhone was killed when the iPhone 3G was launched, the iPhone 3G will be sold no more. The iPhone 3GS would be sold for $99 with a two years contract.

Clad with wonderful new features, Apple will start selling iPhone 4 starting at $199 with a two years contract in U.S. from June 24. The iPhone 4 would be available in a 16GB version costing $199 and 32GB version costing $299. Before we start off with the details of the iPhone 4, let's get one thing straight about the operating system. Apple has renamed the iPhone OS 4.0 for iPad and iPhone/iPod Touch devices to iOS4. From June 21, the iOS4 upgrade will be available free for all devices.

Design:

The all new iPhone 4 is just 9.3mm thick and is 24 percent thinner than the iPhone 3GS. It's pretty much similar to what we saw in the leaked photos that soared on the web. On the top, the iPhone 4 has a 3.5mm headset jack, secondary mic and the sleep-wake up button. At the bottom, the iPhone 4 sports the primary mic, speaker and Apple's proprietary 30-pin connector port. Of course we have the volume controls on the sides.

Design-wise, Apple drops the rounded hinds design and adopts box like structure for the new iPhone 4 model. Apple has used stainless steel rims for binding the iPhone 4 body. These rims have integrated antennas and act as bonding agents to hold two glass panels on the front and the back of the iPhone 4.

Display:

With the new iPhone 4, Apple debuts new display dubbed as 'Retina Display'. This 3.5-inch multi-touch display offers 960x640 pixel resolution at 326 pixels per inch. This means crisper images and more amazing graphics display while playing games. Apart from that, this IPS technology based panel will offer 800:1 contrast ratio that would be four times better than the previous generation iPhone devices.

So, you can comfortably watch 720p HD movies on this 960x640 pixel display with more accurate colors. Apart from that, both front display and back panel would come coated with fingerprint resistant oleophobic coating.

Processor:

If you can recollect the mysterious Apple A4 System-on-Chip processor used in the iPad, you won't be surprised to discover that Apple has used the same A4 processor on the iPhone 4. Apple claims that this chip is power efficient and hence conserves power to add up to the battery life.

Camera:

Apple has added 5 megapixel sensor with backside illuminated sensor and LED Flash. This new camera will also offer five times digital zoom and tap to focus options. Not only that, this 5 megapixel camera sensor is capable of recording 720p HD video at 30 frames per second. The LED Flash will stay illuminated for recording better quality picture in videos.

The iPhone 4 has a front facing camera that enables video calling dubbed as FaceTime that works even when the Wi-Fi is turned off. No setup or installation is required as FaceTime works out of the box. Apple has built FaceTime using a bunch of open standards like SIP (Session Initiation Protoco), H.264, AAC and so on.

Apple will also introduce new iMovie for iPhone app for video editing that will include options like scene transitions, themes, editable titles, and much more. This app will be available at a price of $5 after iOS4 is rolled out to everyone.

Will iPhone 4 turn out to be a killer of Flip Mino HD and the likes? We'll wait and see.

Gyroscope:

Apple has added three-axis gyroscope, a device maintaining orientation or measuring it based on the rotation mechanism of the object. This, clubbed with Accelerometer on the iPhone 4 makes it capable of 6-axis motion sensing. This is similar to Sony PlayStation 3's game controller which has gyroscopic motion sensing. It's quite possible that in the near future, we may see touchscreen apps supplementing the game controllers.

Battery life:

One of the major issues of all the iPhone users has been the battery life and hence, Apple has put a larger battery in the iPhone 4. The lithium-ion rechargeable battery promises to offer up to 7 hours of talk time on 3G networks and 14 hours of talk time on 2G networks. Also, one can listen to music for 40 hours or watch videos for up to 10 hours. The most amazing part is that users can now browser mobile web for up to 10 hours on the iPhone 4, that is as much as offered by new Intel Atom Pine Trail platform based netbooks.

Bumpers:

Since Apple would be using iPhone 4's outer rims as a part of its antenna system, the company has come out with its own set of cases to protect the iPhone. Apple has introduced iPhone 4 protection cases dubbed as Bumpers that would be available in white, black, green, blue, orange and pink colors. Made out of moulded plastic and rubber, these cases are meant to keep the antenna system as well the glass panels safe.

Other features:

• Quadband HSDPA/HSUPA
• Wi-Fi (802.11n)
• Assisted GPS
• Accelerometer
• Digital Compass
• Bluetooth 2.1 + EDR
• iBooks App as free download
• Microsoft's search engine Bing officially added to search engine options.
• Micro SIM just like the ones used in iPad

Quite a lot of features like multi-tasking and folders utilities will arrive with the iOS4 update for other Apple devices but iPhone 4 will come preloaded with it. The iPhone 4 will require iTunes 9.2 so we can anticipate that iTunes software upgrade in the coming weeks. Apple iPhone 4 will be available in white and black colors. Pre-orders begin on June 15 and phones will start shipping on June 24 in U.S., France, Germany, UK and Japan. Apple will roll out the iPhone 4 to 18 more countries in July, 24 more in August, and 40 more in September. Let's hope that India would be considered during August or at least September roll out of iPhone 4 device. Click Here

THE ONLY THING WHICH CAN BE SAID NOW IS THAT APPLE KEEPS REMINDING THAT WHEN IT COMES TO TECHNOLOGY IT HAS NO COMPETITION
