Calculations On Command Prompt

"Calculations On Command Prompt"
the command processor CMD.EXE comes with a mini-calculator that can perform simple arithmetic on 32-bit signed integers:

C:\>set /a 2+2
4
C:\>set /a 2*(9/2)
8
C:\>set /a (2*9)/2
9
C:\>set /a "31>>2"
7

Note that we had to quote the shift operator since it would otherwise be misinterpreted as a "redirect stdout and append" operator.

For more information, type set /? at the command prompt.

Access Free Airtel GPRS Using TeaShark Browser

"Access Free Airtel GPRS Using TeaShark Browser"
TeaShark, a mobile browser like Opera Mini, allow you to access Airtel GPRS for FREE.
Shockingly it has nothing to do with modifying any Airtel settings or any kind of hack.

Here is how I used this

* Download TeaShark v. 312. Its free and being JAR file it can be installed on most handsets.
* Open it from your mobile and select AirTel Live as access point.
* Thats it! Open any site from TeaShark and you wont be charged anything.

Note for the first time, when TeaShark starts, it may take more than one minute to initialize. Also this one time initialization may fail many times. But dont loose your heart!

As of now, this trick is limited to handsets only.

Note : Subscribe to Packet Data First
This means you need to activate AirTel Live service which is free.
Contact customer care to get it activated.
Also select only AirTel Live as access point when prompted by TeaShark.

Download TeaShark :

What was the first operating system?

"What was the first operating system?"
The earliest computers did not use operating systems; a simple loading program was loaded into the computer - via front panel switches or punched tape, the loading program would load the actual program to run. The program would take over the entire machine until it halted or was interrupted by the operator.
This process of loading programs from storage was automated, to some extent, in the 1950s and MIT may be able to claim the earliest such system in 1954 (see attached link).

This is one of the things no one will ever know for sure. When I developed software for the IBM 704 in conjunction with a missile guidance project in 1957, I had never heard of an operating system but I eventually realized that that's what I had created. It's written up in the Annals of the History of Computing, Volume 11 (1989). I can't say that it was first, but it was early, and I don't know any older ones.

In 1961, Burroughs introduced the MCP (Master Control Program) for its B5000 mainframe computer. These early operating systems were little more than loaders. With the advent of high speed disk drives, virtual memory systems and disk control systems became more widely used.

In 1969, Unix was being developed. Unusually for the time, Unix was designed to run on different machines, small device drivers were written for specific hardware, but the bulk of the code was unchanged.

The first microprocessor operating system was CP/M; as with Unix by separating the hardware dependent parts of CP/M from the majority of the code, it made it easy to port CP/M to different hardware platforms (although it was written for the 8080 family of microprocessors).

Operating system

"Operating system"
An operating system is software, consisting of programs and data, that runs on computers, manages computer hardware resources, and provides common services for execution of various application software. Operating system is the most important type of system software in a computer system. Without an operating system, a user cannot run an application program on their computer, unless the application program is self booting.
For hardware functions such as input and output and memory allocation, the operating system acts as an intermediary between application programs and the computer hardware,[1][2] although the application code is usually executed directly by the hardware and will frequently call the OS or be interrupted by it. Operating systems are found on almost any device that contains a computer—from cellular phones and video game consoles to supercomputers and web servers.
Examples of popular modern operating systems are: BSD, Linux (Ubuntu, Fedora, OpenSuSE, Mandriva, Arch Linux, Debian, Linux mint etc.), Mac OS X, Microsoft Windows and UNIX.[3]

"USB 3.0"

"USB 3.0"
In information technology, Universal Serial Bus (USB) is a serial bus standard to connect devices to a host computer. USB was designed to allow many peripherals to be connected using a single standardized interface socket and to improve plug and play capabilities by allowing hot swapping; that is, by allowing devices to be connected and disconnected without rebooting the computer or turning off the device. Other convenient features include providing power to low-consumption devices, eliminating the need for an external power supply; and allowing many devices to be used without requiring manufacturer-specific device drivers to be installed.

The USB 3.0 is the upcoming version of the Universal Serial Bus(USB). The specification of the new standard had been announced by USB Implementers Forum (USB-IF). The main feature of the new USB is the raw throughput is 500 MByte/s. The new USB is also capable to provide more power to drive the devices. USB 3.0 is highly backward compatible that is, it is capable of operating with the current USBs which is USB 2.0

NETBIOS HACKING

"NETBIOS HACKING"
THIS NETBIOS HACKING GUIDE WILL TELL YOU ABOUT HACKING REMOTE COMPUTER AND GAINING ACCESS TO IT’S HARD-DISK OR PRINTER. NETBIOS HACK IS THE EASIEST WAY TO BREAK INTO A REMOTE COMPUTER.
STEP-BY-STEP NETBIOS HACKING PROCEDURE
1.Open command prompt
2.In the command prompt use the “net view
” command
( OR YOU CAN ALSO USE “NB Scanner” OPTION IN “IP TOOLS” SOFTWARE BY ENTERING RANGE OF IP ADDRESSS. BY THIS METHOD YOU CAN SCAN NUMBER OF COMPUTERS AT A TIME).
Example: C:\>net view \\219.64.55.112
The above is an example for operation using command prompt. “net view” is one of the netbios command to view the shared resources of the remote computer. Here “219.64.55.112″ is an IP address of remote computer that is to be hacked through Netbios. You have to substitute a vlaid IP address in it’s place. If succeeded a list of HARD-DISK DRIVES & PRINTERS are shown. If not an error message is displayed. So repeat the procedure 2 with a different IP address.
3. After succeeding, use the “net use” command in the command prompt. The “net use” is another netbios command which makes it possible to hack remote drives or printers.
Example-1:  C:\>net use D:
\\219.64.55.112\F
Example-2: C:\>net use G:
\\219.64.55.112\SharedDocs
Example-3: C:\>net use I: \\219.64.55.112\Myprint

NOTE: In Examples 1,2 & 3, D:,G: & I: are the Network Drive Names that are to be created on your computer to access remote computer’s hard-disk.
NOTE: GIVE DRIVE NAMES THAT ARE NOT USED BY ANY OTHER DRIVES INCLUDING HARD-DISK DRIVES, FLOPPY DRIVES AND ROM-DRIVES ON YOUR COMPUTER. THAT IS, IF YOU HAVE C: & D: AS HARD DIRVES, A: AS FLOPPY DIVE AND E: AS CD-DRIVE, GIVE F: AS YOUR SHARED DRIVE IN THE COMMAND PROMPT
F:,”SharedDocs” are the names of remote computer’s hard-disk’s drives that you want to hack. “Myprint” is the name of remote computer’s printer. These are displayed after giving “net use” command. “219.64.55.112″ is the IP address of remote computer that you want to hack.
4. After succeeding your computer will give a message that “The command completed successfully“. Once you get the above message you are only one step away from hacking the computer.
Now open “My Computer” you will see a new “Hard-Disk drive”(Shared) with the specified name. You can open it and access remote computer’s Hard-Drive. You can copy files, music, folders etc. from victim’s hard-drive. You can delete/modify data on victim’s hard-drive only if WRITE-ACCESS is enabled on victim’s system. You can access files/folders quickly through “Command Prompt”.

How to quickly repair your Mobile Phone dropped in water?

"How to quickly repair your Mobile Phone dropped in water?"
Many of you get your mobile phone wet by one way or another. You worry as you mistakenly drop your mobile phone in water. It can also get wet if you are out in a heavy rain.  However, there is no need to panic. It is possible to save your wet mobile phone by quickly repairing it. In order to save your mobile phone from water damage, you can consider these easy and simple solutions:
Act rapidly :
The first thing you have to do in order to save your wet mobile phone is to act rapidly. Quickly remove all the detachable parts as well as covers possible such as the back cover, battery, the SIM card, memory card etc. Next, take a piece of cloth or a tissue paper to wipe the excess water you are able to notice within the mobile phone. Make sure that you dry it completely. If you don' t do this, the water inside the mobile phone will begin to evaporate and gather in places which will be difficult to reach.

This will save your wet mobile phone and it will start working if it was under water for just a little while.
Using a hairdryer :
Take a hairdryer and begin drying the mobile phone while giving more consideration to the place where the battery is located. The battery housing usually consists of tiny holes to let in air (so giving more space for water) inside the mobile phone.
Make sure that you are not holding the hairdryer very near to the mobile phone. Keeping it too close to the mobile phone may harm the electrical mechanism of the mobile phone. Keep on drying the mobile phone from a safe distance for about twenty to thirty minutes.
If solution number 1 and solution number 2 don't work, try solution number 3. 
Drying for a long time:
Take off the covers as well as battery from the mobile phone. Put the phone in a dry as well as warm place to let the water inside the phone evaporate gradually from the little holes in the mobile phone.
