Step 1:

Open the command prompt. (start->All programs->accessories->cmd)

Type as

DISKPART

and hit Enter

Step 2:

Now type as

list volume

This will list the available volume.

Step 3:

Now we need to select the drive . so use this command “select volume volume_no”

replace the volume_no in this command with ‘###’ value of drive which you want to hide.

For eg:

I am going to hide the E drive. ### no for E drive is 2. so the command is

select volume 2

Step 4:

Type as “remove letter drive_lettter”

Replace the drive_letter your drive letter which you want to hide.

I am going to hide E drive ,so

remove letter E

Now your drive will be hidden

type “exit” to exit from the Diskpart.

Step 5:

To make your drive to visible

follow the 1,2,3 steps.

then type as “assign letter drive_letter”

Replace the drive_letter with your drive letter.

I am going to make my E drive visible.

so

assign letter E

Type exit and hit enter to exit from the diskpart

Boffins Beam 800 mbps Wireless Network From Flashlight!

August 3, 2011 Leave a comment
German researchers have found out how to fill a room with 800 megabits per second of wireless data employing an inexpensive LED setup. Researcher Klaus-Dieter Langer said, ”Using red-blue-green-white light LEDs, we were able to transmit 800Mbit/s in the lab. That is a world record for the [visible light communication] method.”

Langer, operating at Berlin’s Heinrich Hertz Institute, a branch of Fraunhofer Institute for Telecommunications, also accounted an earlier experiment that reached 100Mbit/s using only white-light LEDs. ”We turn the LEDs off and on in very rapid succession and transfer the information as ones and zeros,” he explained. “The modulation of the light is imperceptible to the human eye. On the receiving end is a simple photo diode, and circuitry that changes the diode’s signals into a digital data stream. According to Langer, advantages of this method admit the simplicity of changing the LEDs into signal-sending devices, and the riddance of cabling as a signal-transferring medium.
In the 100 Mbit/s experiment, the signalling LEDs were situated on the ceiling, and the transmission was error-free in an area of 10 square meters, received by a group of four photo diode–fitted laptops. HHI researcher, Anagnostis Paraskevopoulos said, ”We transferred four videos in HD quality to four different laptops at the same time.” Applying visible light as a signaling medium instead of radio waves has clear advantages in areas such as hospitals and aircraft where radio transmission is not possible and where cabling would be discouragingly expensive.
The most evident disadvantage of visible light communication (VLC) is that the signal can be easily barred by any solid object, for example a hand moving between the LEDs and the photo diode. The unfitness for light to penetrate walls also limits VLC to special-case scenarios. As limited as VLC may seem, when The Reg spoke in June with Aicha Evans, wireless engineering manager at Intel, she stated that “a lot of people are talking about visible light.”
Though Evans accepted that “it’s still science fiction,” VLC may very well show its value in the last few meters of a data stream. If at this early phase of its evolution it’s already being demonstrated at 800Mbit/s speeds, VLC may very well prove to be a functional high-speed, within-four-walls broacast WLAN in future executions.

How computers can cure cultural diabetes

July 5, 2011 Leave a comment


The networked computer offers an antidote to the junk culture of broadcasting. Why not choose the healthy option?
Using computers to create will benefit human culture (Image: Jasper James/Getty)
THINK of those fleeting moments when you look out of an aeroplane window and realise that, regardless of the indignities of commercial air travel, you are flying, higher than a bird, an Icarus safe from the sun. Now think of your laptop, thinner than a manila envelope, or your cellphone nestled in the palm of your hand. Take a moment or two to wonder at those marvels. You are the lucky inheritor of a dream come true.
The second half of the 20th century saw a collection of geniuses, warriors, pacifists, cranks, entrepreneurs and visionaries labour to create a fabulous machine that could function as a typewriter and printing press, studio and theatre, paintbrush and gallery, piano and radio, the mail as well as the mail carrier. Not only did they develop such a device but by the turn of the millennium they had also managed to embed it in a worldwide system accessed by billions of people every day.
The networked computer is an amazing device, the first media machine that serves as the mode of production (you can make stuff), means of distribution (you can upload stuff to the network), site of reception (you can download stuff and interact with it), and locus of praise and critique (you can talk about the stuff you have downloaded or uploaded). The computer is the 21st century’s culture machine.
But for all the reasons there are to celebrate the computer, we must also tread with caution. This is because the networked computer has sparked a secret war between downloading and uploading – between passive consumption and active creation – whose outcome will shape our collective future in ways we can only begin to imagine. I call it a secret war for two reasons. First, most people do not realise that there are strong commercial agendas at work to keep them in passive consumption mode. Second, the majority of people who use networked computers to upload are not even aware of the significance of what they are doing.
All animals download, but only a few upload anything besides faeces and their own bodies. Beavers build dams, birds make nests and termites create mounds, yet for the most part, the animal kingdom moves through the world downloading. Humans are unique in their capacity to not only make tools but then turn around and use them to create superfluous material goods – paintings, sculpture and architecture – and superfluous experiences – music, literature, religion and philosophy. Of course, it is precisely these superfluous things that define human culture and ultimately what it is to be human. Downloading and consuming culture requires great skills, but failing to move beyond downloading is to strip oneself of a defining constituent of humanity.
For all the possibilities of our new culture machines, most people are still stuck in download mode. Even after the advent of widespread social media, a pyramid of production remains, with a small number of people uploading material, a slightly larger group commenting on or modifying that content, and a huge percentage remaining content to just consume. One reason for the persistence of this pyramid of production is that for the past half-century, much of the world’s media culture has been defined by a single medium – television – and television is defined by downloading.
Television is a one-way spigot gushing into our homes. The hardest task that television asks of anyone is to turn the power off after they have turned it on. The networked computer offers the first chance in 50 years to reverse the flow, to encourage thoughtful downloading and, even more importantly, meaningful uploading.
What counts as meaningful uploading? My definition revolves around the concept of “stickiness” – creations and experiences to which others adhere. Tweets about celebrity gaffes are not sticky but rather little Teflon balls of meaninglessness. In contrast, applications like tumblr.com, which allow users to combine pictures, words and other media in creative ways and then share them, have the potential to add stickiness by amusing, entertaining and enlightening others – and engendering more of the same. The explosion of apps for mobile phones and tablets means that even people with limited programming skills can now create sticky things.
The challenge the computer mounts to television thus bears little similarity to one format being replaced by another in the manner of record players being replaced by CD players. It is far more profound than that, because it can bring about a radical break from the culture of television and a shift from a consumption model to a production model.
This is a historic opportunity. Fifty years of television dominance has given birth to an unhealthy culture. Created like fizzy drinks and burgers by multinational conglomerates, the junk culture of broadcasting has turned us into intellectual diabetics. The cure is now in our collective grasp. It involves controlling and rationing our intake, or downloading, and increasing our levels of activity – uploading. Not to break it down too much, watching is ingesting is downloading and making is exercising is uploading.
Of course people will still download. Nobody uploads more than a tiny percentage of the culture they consume. But the goal must be to establish a balance between consumption and production. Using the networked computer as a download-only device, or even a download-mainly device, is a wasted opportunity of historic proportions.

Scientists Developing Robotic Hand of the Future

July 5, 2011 Leave a comment

Researchers at Carlos III University of Madrid’s (UC3M) Robotics lab are participating in the international research project known as HANDLE. The objective of the project is to create a robotic hand that can reproduce the abilities and movements of a human hand in order to achieve the optimal manipulation of objects
HANDLE is a large scale “Integrated Project” that is part of the Seventh European Framework Programme FP7; Spain is a participant in the project, whose goal is to reach an understanding of how humans manipulate objects in order to replicate its grasping and movement abilities in an artificial, anthropomorphic articulated hand, thus endowing it with greater autonomy and producing natural and effective movements. “In addition to the desired technological advances, we are working with basic aspects of multidisciplinary research in order to give the robotic hand system advanced perception capabilities, high level information control and elements of intelligence that would allow it to recognize objects and the context of actions,” explains the head researcher on the UC3M team working on this project, Mohamed Abderrahim, of the Madrid university’s Department of Systems Engineering and Automation.
His team has already gotten very good results, in his opinion, in the areas of visual perception, and cinematic and dynamic systems, which allow the system to recognize an object in its surroundings and pass the information on to the robotic hand’s planning and movement system.
The robotic hand that these researchers are working with is mostly made up of numerous high precision pieces of mechanized aluminum and plastic, as well as sensor and movement systems. In all, it has 20 actuators and can make 24 movements, the same as a human hand. Its size is also the same as that of an average adult male’s hand and it weighs approximately 4 kilograms. According to the partner in the project who manufactures the hand, the approximate cost of the version that is currently in development at UC3M comes to about 115,000 euros.
The problems involved in imitating a hand
When trying to recreate the movements of a human hand with a robotic system, there are several complex problems that must be resolved. In the first place, there is a lack of space. This is because “a human hand is incredibly complete, which makes it a challenge to try to put all of the necessary pieces into the robotic hand and to integrate all of the actuators that allow for mobility similar to that of a human hand,” comments Professor Mohamed Abderrahim. Second, another problem is that there are currently no sensors on the market that are small enough to be integrated into the device so that it can have sensitivity similar to that of a human hand and, thus, be able to make precise movements. Finally, although the researchers may manage to make a perfect robot from the mechanical and sensorial point of view, without intelligence elements the device will not be able to function autonomously nor adapt its movements and control to the characteristics of the objects, such as their geometry, texture, weight or use.
“It is not the same to take hold of a screwdriver to pass it to someone, or to put it away, as it is to use it, because in the last situation, it has to be reoriented in the hand until it is in the right position to be used. This position has to be decided by the intelligence part of the robotic hand,” the researchers say. “A robotic hand that is able to perform this seemingly simple task autonomously,” they say “only exists in science fiction movies.” “My personal estimation is that it will take around 15 years of research into these areas to build a robotic hand that is able to perform certain complex tasks with a level of precision, autonomy and dexterity that is similar to that of a human hand,” predicts Professor Abderrahim.
The research carried out by the HANDLE project’s partners has brought about results that are very interesting in the area of visual perception, motion planning, new sensors, acquisition of motor skills using artificial intelligence techniques, etc. Nevertheless, important challenges still remain when it comes to integrating the results obtained by all of the partners into a single system, which will be the result of the next two years of work.
HANDLE (Developmental pathway towards autonomy and dexterity in robot in-hand manipulation) is a Large Scale “Integrated Project” funded by the European Union within The Seventh Framework Programme FP7, in which nine European institutions, coordinated by the Pierre and Marie Curie University of Paris (France), participate
