- Ubiquitous computing is the method of enhancing computer use by making many computers available throughout the physical environment, but making them effectively invisible to the user .(def by: – Mark Weiser who coined this term around 1988).
- Ubiquitous computing, or calm technology, is a paradigm shift where technology becomes virtually invisible in our lives. Instead of having a desk-top or lap-top machine, the technology we use will be embedded in our environment
- Ubiquitous or pervasive computing (often abbreviated to “ubicomp”) refers to a new genre of computing in which the computer completely permeates the life of the user.
- It is the age of calm technology, when technology recedes into the background of our lives.
Examples:
- Gesture recognition
- speech recognition
- Free form pen interaction
- computational perception etc.
- Ubiquitous Home project
Ubiquitous Home project: Ubiquitous home projects implemented during 1990’s in order to overcome the drawbacks of Home Automation (HA)systems.Purpose of each smart home project is mainly targeted at how to detect the residents’ situation and their contextual information in a real life.
Another scenario : A domestic ubiquitous computing environment might interconnect lighting and environmental controls with personal bio-metric monitors woven into clothing so that illumination and heating conditions in a room might be modulated, continuously and imperceptibly.

Photovine ,another product from Google team for photo sharing and meeting new people across the globe,it have some sort of privacy policy for protecting the users account with high level security. "Photovine is a fun way to learn more about your friends, meet new people, and share your world like never before.” “Photovine is a community that’s about creating fun and unique collections of photos that we call Vines,” the support page says, explaining that a vine is “like a constantly growing family of photos connected through a common caption created by you, your friends, and people all over the world”. Note: Photovine is free to download and it is supported in mobiles also,only fact is we need to invite by photovine to access For invitation and get more details follow this link http://photovine.com/

Introduction:
The digital scent technology we are able to sense, transmit and receive a smell-trough the internet, smell a perfume online before buying them, check to see if food you are buying is fresh, smell burning rubber in your favorite racing game, or sent scented e-cards from scent enable websites. As this technology gains mass appeal , there is no stopping it from entering into all areas of virtual world. Imagine being able to smell things using a device that connects to your computer. Digital scent technologies is making this a reality.
Components:
There is a complete software and hardware solution for scenting digital media and user. It includes a personal scent synthesize for reproducing and electronic nose for the detection of the smell. These two peripheral components connected to the computer and the communication network for the transmission of the digitized smell data does comprise the digital scent technology and communication.
Technological idea behind it
Digital scent technology digitizes the scent by digitizing the scent along two parameters the chemical make and its place in scent spectrum then digitized into a small file which can be transmitted to the internet attached to the enhanced web content. Then with the help of digital synthesizer connected to the computer the transmitter scent can be reproduce from the palette of primary odors following the guidelines of the digital file.
Areas of Applications:
Digital scent technologies find its wide range of applications in scentertinment-movies, music and games, in communication which includes websites which is enhanced with scent. It also has its relevance in E-commerce which will make online-shopping compelling and fun. This technology also helps in advertising fields in making the advertisement more memorable and engaging. Many companies working in the field of digital scent technologies are developing a new technology for identifying dementing brain disorders, including Alzheimer’s, Hunting tone’s, and parking son’s and for differentiating them from other mental disorders. This method is based on detecting the olfactory deficits that are diagnostic of the deminating diseases.
Sometimes we get irritated if our favorite website is not opened,it may blocked because of some reasons.Here comes solution for these kind of problems.
Follow these steps:
1.open the Notepad
2.Enter the below
@echo off title web blocked nslookup
3.Save it as in batch file format in desktop
e.g block.bat
4.Then click the batch file(block.bat) it will pop up command prompt.
5.There you type website url
6.After that,command prompt displays some IP address of website you typed.
7.Copy the IP address and enter it into browser tab,then you will be directed to the particular site.

Green computing
Posted on: August 5, 2010
Green computing or green IT, refers to environmentally sustainable computing or IT. In the article Harnessing Green IT: Principles and Practices, San Murugesan defines the field of green computing as “the study and practice of designing, manufacturing, using, and disposing of computers, servers, and associated subsystems—such as monitors, printers, storage devices, and networking and communications systems—efficiently and effectively with minimal or no impact on the environment..The goals of green computing are similar to green chemistry; reduce the use of hazardous materials, maximize energy efficiency during the product’s lifetime, and promote the recyclability or biodegradability of defunct products and factory waste. Research continues into key areas such as making the use of computers as energy-efficient as possible, and designing algorithms and systems for efficiency-related computer technologies.
Modern IT systems rely upon a complicated mix of people, networks and hardware; as such, a green computing initiative must cover all of these areas as well. A solution may also need to address end user satisfaction, management restructuring, regulatory compliance, and return on investment (ROI). There are also considerable fiscal motivations for companies to take control of their own power consumption; “of the power management tools available, one of the most powerful may still be simple, plain, common sense.”
utility computing
Posted on: August 5, 2010
Utility computing is the packaging of computing resources, such as computation and storage, as a metered service similar to a traditional public utility (such as electricity, water, natural gas, or telephone network). This system has the advantage of a low or no initial cost to acquire hardware; instead, computational resources are essentially rented. Customers with very large computations or a sudden peak in demand can also avoid the delays that would result from physically acquiring and assembling a large number of computers.
“Utility computing” has usually envisioned some form of virtualization so that the amount of storage or computing power available is considerably larger than that of a single time-sharing computer. Multiple servers are used on the “back end” to make this possible. These might be a dedicated computer cluster specifically built for the purpose of being rented out, or even an under-utilized supercomputer. The technique of running a single calculation on multiple computers is known as distributed computing.
The term “grid computing” is often used to describe a particular form of distributed computing, where the supporting nodes are geographically distributed or cross administrative domains. To provide utility computing services, a company can “bundle” the resources of members of the public for sale, who might be paid with a portion of the revenue from clients.
One model, common among volunteer computing applications, is for a central server to dispense tasks to participating nodes, on the behest of approved end-users (in the commercial case, the paying customers). Another model, sometimes called the Virtual Organization (VO). is more decentralized, with organizations buying and selling computing resources as needed or as they go idle.
The definition of “utility computing” is sometimes extended to specialized tasks, such as web services.
