Make your pen drive Bootable

     I just did this method on one of my friends machine and installed the new Windows 7 BETA. The main advantage is that by using USB drive you will be able to install Windows 7/Vista in just 15 minutes. You can also use this bootable USB drive on friend’s computer who doesn’t have a DVD optical drive.

    The method is very simple and you can use without any hassles. Needless to say that your motherboard should support USB Boot feature to make use of the bootable USB drive. 

Requirements: 

*USB Flash Drive (Minimum 4GB)

*Windows 7 or Vista installation files.

Steps:

    Follow the below steps to create bootable Windows 7/Vista USB drive using which you can install Windows 7/Vista easily. 

1. Plug-in your USB flash drive to USB port and move all the contents from USB drive to a safe location on your system.

2. Open Command Prompt with admin rights. Use any of the below methods to open Command Prompt with admin rights.

*Type cmd in Start menu search box and hit Ctrl+ Shift+ Enter.
Or
*Go to Start menu > All programs > Accessories, right click on Command Prompt and select Run as administrator.

3. You need to know about the USB drive a little bit. Type in the following commands in the command prompt:
    First type DISKPART and hit enter to see the below message.
    Bootable USB Drive
    Next type LIST DISK command and note down the Disk number (ex: Disk 1) of your USB flash drive. In the below screenshot my Flash Drive Disk no is Disk 1.

4. Next type all the below commands one by one. Here I assume that your disk drive no is “Disk 1”.If you have Disk 2 as your USB flash drive then use Disk 2.Refer the above step to confirm it.

So below are the commands you need to type and execute one by one:

SELECT DISK 1

CLEAN
CREATE PARTITION PRIMARY
SELECT PARTITION 1
ACTIVE
FORMAT FS=NTFS
     (Format process may take few seconds)
ASSIGN
EXIT
Don’t close the command prompt as we need to execute one more command at the next step. Just minimize it.

Bootable USB Drive

5. Next insert your Windows7/Vista DVD into the optical drive and check the drive letter of the DVD drive. In this guide I will assume that your DVD drive letter is “D” and USB drive letter is “H” (open my computer to know about it).

6. Maximize the minimized Command Prompt in the 4th step.Type  the following command now:

  D: CD BOOT and hit enter.Where “D” is your DVD drive letter.
  CD BOOT and hit enter to see the below message.

7. Type another command given below to update the USB drive with BOOTMGR compatible code.

  BOOTSECT.EXE /NT60 H:
  14
  Where “H” is your USB drive letter. Once you enter the above command you will see the below message.

8. Copy your Windows 7/Vista DVD contents to the USB flash drive.

9. Your USB drive is ready to boot and install Windows 7/Vista. Only thing you need to change the boot priority at the BIOS to USB from the HDD or CD ROM drive. I won’t explain it as it’s just the matter the changing the boot priority or enabling the USB boot option in the BIOS.

Note: If you are not able to boot after following this guide means you haven’t set the BIOS priority to USB. If you got any problem in following this guide feel free to ask questions by leaving comment.

Human Brain vs Computer Technology

One silly question. How much information can the world transmit, process, and store? Estimating this sort of thing can be a nightmare.

Computing capacity is converted into MIPS, and estimates for the total number and class of chips are available. The big question mark here is mostly in embedded controllers; it's hard to estimate both their computational capacity and how many are out there.
STORAGE
Some trends are very, very obvious. Analog video accounted for over half the data stored in 1986, and video held 86 percent of all stored data by 1993.By 2000, CDs and digital tape started pushing back, but analog video still stood at 70 percent of all stored data. By 2007, analog video had plunged to a tiny six percent, eclipsed by hard disks, Blu-ray and DVDs, and digital tape.During that time, total storage capacity grew at about 23 percent annually, and it topped out at 2.9 x 10 <<to the power>> 20  bytes—that's about 300 exabytes, or 61 CDs for everyone on the planet.

    A similar shift to digital occurred in broadcast media and two-way communications. Back in 1986, 80 percent of broadcast capacity was used for terrestrial TV, although analog cable was already a presence. Today, broadcast TV has fallen to 50 percent; a quarter of the broadcast data is now some form of digital, and analog cable is declining from its peak in 2000.
    Now about two-way communications,it underwent a far more dramatic shift. In 1986, analog phones handled 80 percent of the data, with digital phones taking the other 20 percent; everything else was a rounding error. By 2000, analog telephony was down to two percent of the world's two-way transmissions.Digital telephony peaked in 1993 at 67 percent; fixed Internet connections accounted for one percent of usage that year. By 2000, it was up to 50 percent, and it's now at 97 percent.while broadcasting is increasing at a linear rate, the advent of the Internet has given two-way transmissions a big boost, increasing the bytes transmitted by a factor of 29 in just 7 years.
COMPUTATION
    When computation comes to concern, back in 1986, pocket calculators represented about 40 percent of all computer capacity, beating out PCs at 33 percent and servers at 17 percent. Even then, gaming hardware held a nine percent share.
    Calculators were gone by 2000, when the PC peaked at 86 percent and the mobile phone/PDA first appeared at 3 percent. By 2007, phones held six percent of world processing power, but the big story was gaming hardware, which shot up to a quarter of the total computational capacity, pushing the PC back down to a two-thirds share. Supercomputers are apparently rare enough not to measure.

    One surprising result of the research is the amount of total horsepower found in the application-specific space, where the authors considered only DSPs, microcontrollers, and GPUs (GPUs alone account for 97 percent of this category's capacity). And that capacity is huge, about 30 times that of all the general purpose computation hardware. GPUs account for the lion's share of the 6.4 x 10¹⁸ operations a second that the planet can now perform, and they showed a compound annual growth rate of 86 percent over the study period.




Now after figureing out all these data the authors make some comparisons with biology. "To put our findings in perspective, the 6.4*10¹⁸ instructions per second that human kind can carry out on its general-purpose computers in 2007  are in the same ballpark area as the maximum number of nerve impulses executed by one human brain per second," they write.

Our total storage capacity is the same as an adult human's DNA. And there are several billion humans on the planet.

Google dashboard: Something may new to you about google

"Everyone who has a Google account should visit their Dashboard once a year," this what Google product manager Jonathan McPhie is saying. But what is Google Dashboard. This is somthing like a container which contain some important about you and about your activity related to your Google account.
         Google sure does spread its settings out into a million places. There are settings in every single Google service—Gmail, Google maps, Blogger, YouTube, Reader, Buzz—and some of them cross over, while others don't.
 Lets have a look how it look like.

Here you can see a list of every Google product you have an account with, as well as the information each one has stored about you. This picture is not all about. There are many more thing which you cann't belive that you have done something and you forget but Google remember it and store everything in its dashboard.

        It store the information about Google AdSense which you have created, what you have store in your Google library,how many Document you have in Google Docs and many more. More interesting thing is it also keep track about what you have purchased online and all conversation detail using G-talk or usng other tool till now with your friend.
    This also facilitate you to clear all items as well as you can manage other gadgets using the link.So why not to have look upon own Dashboard.

How to hide a computer hard drive ?

Each partition in a hard disk is assigned with a unique letter. So to hide a single partition just remove that assigned letter and u will see that respective hard drive will disappear from windows explorer.
Step:
1: Go to Start.
2: Select Run command .
3: Type Cmd and press enter.
4: Type diskpart and press enter
5: Type list volume and press enter
6: Find out the volume number you want to hide and enter the command select volume <your volume number>
7: Now enter the command remove letter <your volume number>
Note: To unhide the letter in step 7 type assigned instead of remove.
