On Monday, the Kayak’s iPad app has got a recent update 12.2.0 which has reached the App store which has a new feature termed as Explore. This will guide the user in estimating the place where they can go based on the amount of cash they are ready to spend, the type of weather that they want to enjoy and the actions that they want to do after reaching that location.

Kayak has changed its app name after the new update in order to show the app’s real function. Before the update, it was referred to as Kayak Flights and now after the update it is called as Kayak Explore & Flight Search.

Working of Explore: Once you start the application, you can select the destination place by selecting a button on the screen at the top right end. There will be 3 pop down panes at the bottom, where you can select the place you want to go, the type of activities that you want to enjoy and the weather condition of the place you are looking for, and an option to allow to pick a nonstop flight or not. When you have given your requirements, an orange coloured dot will emerge on the world map and on selecting the dot, will give you information about the destination and the cost for travelling to the point in flights. You can zoom in and out of the map by using the zoom feature on the app. You can refine your search with the slider at the top, by specifying your maximum and minimum cost that you are willing to pay. While you move your slider various dots may appear or disappear on the map.

The multi pane look on Kayak application will allow you to look out for flights, rooms and rent cars. You can activate the view by clicking at the flight button at the top. The update will allow you to do multi city searches.

This newly updated app is free and works on iOS 3.2 or higher.

The developer created the Anti Theft Alarm app after being inspired by the world famous Viper car alarm systems. The app can be used in iPad, iPod and iPhone. If you installed the app, you will be able to set the alarm when you are about to leave your iPhone. If someone happens to move your iPhone, the alarm will sound aloud. After setting the alarm, you must quickly set it down within 5 seconds.

The app has a built in accelerometer. The accelerometer is able to detect movement of the phone. The alarm is a combination of 7 types of car alarm sound. The loud sound is designed to frighten the thief and bring attention to the owner. When the alarm sounds, the phone will vibrate. It also show police light animations. While the alarm is sounding, a car alarm message that says “please step away from the phone!” can be heard.

The app is useful for people that want to leave their phone in public place. If you are at the library, you can activate the alarm system to prevent people from stealing it while you are away. It is not suitable for people that are leaving their phone at home. Since you are away, you will never know if someone tries to steal your phone when the alarm sounds.
In addition, the app is easy to be deactivated. You just have to press the home button to deactivate the alarm. Therefore, the alarm is not effective and cannot be used to protect your iPhone in real life. It will work only if you are away to a nearby place and attending to it. The app does not recognize the owner of the iPhone. Anyone who comes across it can just press the home button to deactivate the alarm and steal it. Just like most of the app in the app store, it is a fun gadget that can be used to pull prank on your friend. The Anti-Theft Alarm app is for sale at $1 at Apple’s app store. It operates on MAC OS 3.1.3 and beyond.

In the era when cloud computing and open sourced development is in progression, Google has launched a new programming language “Go”. This is an open sourced language based on C programming family. As also it incorporates elements of python and Pascal, which will help make the web pages faster and dynamic.

The computers are becoming more and more compact and advanced but the software development is far more sluggish. Today when web and computing have changed so dramatically and have reached upto cloud computing yet the languages empowering these developments are the same. Thus, “Go”, an amalgamation of python and C++ is expected to bring a revolutionary change in the computing world. Go seems to be more inspired by python , as python being one of the favourite languages practised by Google since the time, Google search engine was launched solely using python.

The “Go” language has been in development since Sep 2007, but is supposed to be revealed by Google along a free open source computer. One feature of ‘Go’ which makes an excellent innovation is that it has all the commonly used features like trash collection, maps, referring different parts using a single syntax etc. In the existing languages one had to choose efficient compilation, implementation or ease of programming all the features together were never available in the same current language. ‘Go’ is an attempt to combine the ease of programming of an interpreted and dynamically typed language. This language aims to the new computing world where all the applications and softwares will be available through various networked and multicore systems. This is expected to be very fast with the web pages and various other applications.

“Go” has very attractive features but to meet and maintain all of them is also very essential. This will be fulfilled by an expansive but lightweight system which will accompany the launch of “Go”. Later on you never know this might conquer the other systems too.

If you know the basics of C and python it won’t be difficult at all for you to understand the below code.

{
package main
import “fmt”
func main ()
fmt, printf(“Hello World” \n)
}
Output:
“Hello World”

There are various natural sources of energy like wind, solar, hydrogen and tidal waves. If these can be used at a wider scale can bestow an orotund economic boon for the nation. As these are clean sources of energy, they can become beneficial for nature and mankind. Man today has become more intellectual and smart. No doubt that the world has immensely advanced and explicated. But seeing the other side of this scenario, we have ruined the nature for a more a civilized lifestyle. So instead of adopting the route where we favour civilization against environment and nature, we should adopt the one which can have both going hand in hand. So we take a crucial step towards this by efficiently utilise the radiated solar energy for various purposes.

Solar power is generated by collecting the sunlight and converting into electricity by solar panels which are made up of solar cells. This energy collected and stored can be useful for many applications like the major one is to generate electricity. The alternatives can be for cooking by using various solar cookers, cooling your home by using solar air conditioners, solar chargers and solar watches. Taking into account all these applications and benefits of solar energy the world is unanimously progressing towards the development in this field.
Solar parking lot: – This is the first solar parking lot in Isla Vista, Santa Barbara County, California. This was the first solar powered parking lot which can sustain the sunlight and light up its own lights. As also the future electric vehicles can be charged here too.

Solar trees in the parking lot:
Dell sets up a very innovative way set up by Envision Solar to set up solar powered lights as also providing shade for parking spaces , an innovative way to use sunlight as a viable energy source.

World‘s largest solar power project:
India is one of the leading countries in the development of alternative sources of energy. This is a project in Gujarat state which was previously to provide 500 MW of electricity by 2014. But this has now increased to 3,000 MW.
Storage of solar energy:

MIT professor, Daniel Nocera who worked on catalysts found out that water molecules can be divided and can be utilized to store energy. He is known a “huge centralized energy person “.His recent researches are to find cheap ways to store solar energy and reuse it. Apart from this the has also found a chemical which is easily available and cheap for this purpose.

Many such projects are coming up all over the world every day. Thus ,we see that solar is the future technology which has to be made available at a larger scale at a cheaper and efficient way for current systems to work on it and make the environment eco friendly by using carbon free fuels.

Google is not a search engine, it is in fact one of the biggest company till date. With various successes through Google earth, Google navigator, Google chrome a long list to go. Google has always stood undefended by its research and development of their totally outstanding products. So , on July 7th 2009,Google announced its new operating system “Google Chrome OS”. They embarked their beginning to the era of operating systems. “Google Chrome OS” is going to be an open sourced , internet based operating system which will be based on Linux platform. This is mainly targeted for netbooks initially, but will be soon be available for desktops too. The focus of this OS is for people who spend most of their time on the internet. Google OS is a complete package of operating system consisting of web applications, Google navigator, Google wave and gear. The design goal for the Google OS will be to minimise the space and increase the number of applications, which is going to be a big task and challenge for Google. Also, they are working on the split screen feature where you can view various other contents side by side.

Android and Google chrome OS are the two latest ventures of Google. Though these two are completely different from each other and are developed for various purposes , one for mobile and other for netbooks but as said by Google “these might merge in the near future”. This OS will be supported by x86 and ARM hardware. The operating systems were developed when there was no web so now is the time to develop what can cope up with the ever changing requirements of the users. Google says that Google OS is just the extension of Google Chrome where they are working to satisfy their agenda of “speed, simplicity and security”. The designing of the OS is expected to be flawless so that the users may not have to deal with any security hazards or viruses.

So, as we see the competition to innovate an open sourced system is growing each day. But we can trust Google on creating something really unique and dynamic and hope they continue to invent more knowledgeable and innovative products in the near future.

In the history of mobile phones we come across 4 different eccentrics viz 0G, 0.5G, 1G, 2G, 2.5G, 3G and the latest being 4G which is also sometimes referred as super 3G.

OG: This generation experienced the development of two way radio telephones. Which was successfully tested by soviet engineers G.Shapiro and I.Zaharchenko in 1964, and mounted it inside a car, train and airplanes? This was the device which could connect to local telephone network within a range of 20kms.

0.5G: This was a little upgraded from 0G by introducing ARP, the first public commercial mobile phone network which overcame the limited coverage area drawback.

1G: This generation introduced the wireless technology, mobile technology. It used analog type of radio signals for the transmission of voice. The voice signal transmitted was modulated to higher frequency of 150MHz and above.

2G, 2.5G, and 2.75G: In 19th century second generation was introduced. Which bought GSM, IS-136 and IS-95? Out of which IS-136 use TDMA (time division multiple access) and IS-95 uses CDMA (code division multiple access. 2G introduced wireless transmission via digital signals using circuit switched technique. It bought new variant in telecommunication by introducing SMS (short message service) and multimedia access on the mobile phones.

3G: 2G is widely used worldwide now. But due its limited data rates it’s difficult to use applications like video conferencing, video and music download. Thus, to overcome these drawbacks 3G came into existence which has wider bandwidth and high data rate of about 2Mbps by using packet switching mode of transmission.
The first commercial launch of 3G was on October 1,2001, by NTT DoCoMo. They used WCDMA technology which is better than CDMA. This generation encourages video telephony using EDGE which is the latest GSM technology which supports high rate multimedia. We also have an advanced 3G mobile telephony protocol HSDPA (high speed downlink packet access) which allows data transfer at high speeds.

4G: This is the future generation of telecom industry. Which is fastest and more efficient than 3G? 4G will provide data rate of 100 Mbps for high mobility and 1Gbps for low mobility.

And you never know there is a high possibility of 4G coming to India before 3G.

• It uses “adaptive processing”, which helps in the reduction of channel interference and reception by constantly switching channels.
• It uses “smart antennas”, which has higher directivity increasing the efficiency of receiving the radio signals transmitted from the terminal end.
• High network capacity and smooth handoffs between heterogeneous networks.
• Providing ease of access for wireless broadband services, multimedia messaging (MMS), mobile TV, HDTV, video conferencing.
• It uses IP, packet switched network which is capable of utilising all it resources effectively.
• Power saving mechanisms and advanced QoS.
• It provides low latency for real time applications.
• 4G works on variable data rates as it switches its channel frequently as it uses OFDM. OFDM provides high spectral efficiency. OFDM also provides high resiliency to RF interference and multipath distortion is low, due to which the inter symbol interference (ISI) is very low. As also due to soft handoffs, the voice clarity is extremely high.

As technology progresses it makes our lifestyle more and more leisurely. With the high mobility and less of time, are the biggest constrains 4G can resolve.

4G will bring a revolutionary change in the wireless technology, where such different access technologies as cellular, cordless, wireless LAN type systems, short-range wireless connectivity, and wired systems will be
Combined on a common platform to complement each other in the best possible way. The development is expected to inspire the progressive trend in the current technology.
The elementary purpose of 4G service is to be interactive due to convergence network which is applicable for home-networking, telemetric, and sensor-network service.

4G will commercialize the current scenario. But due to high cost and hi-tech infrastructure needed there is being delay in 4G to come up in INDIA. But, it’s not like 4G technology is not present in the market. Recently, NTT Docomo has declared to launch 4G services in Japan around 2010-2015. Providing maximum data transfer rate of 20 Mbps.

4G to be launched in two cities of U.S. by Verizon this year, using 700 MHz frequency band.
Zain Internet Service provider (ISP) and Mada has announced the formal launch of the 4G wireless broadband WiMax E-version service. The announcement was made Wednesday the 25th of March. This was held at an event organised by both companies under the auspice of the Minister of Information and Communications Technology Eng. Bassem Al Rousa.
This service offers high speed wireless broadband internet to customers.

The 4G wireless broadband internet service will be accessible and read for use through Motorola Wi-Max solution. This service is going to be the first of its kind in terms of speed, strength of coverage, geographic outreach, and the availability of a user friendly plug and play devise.

Also, Sprint is working on a WiMAX-enabled Smartphone that will support both 4G and 3G connectivity. WiMax-connected device will run three or five times faster than the 3G connected devices with varied features including video conferencing, improved multimedia quality with high definition and low latency. Thus, seeing the recent scenario we can conclude that it is inevitable that 4G will replace 3G in the long run. There are still chances of 4G to flourish due to new innovations and adaptive changes in the technology.

Cloud computing is broadly classified in three eccentrics:

Cloud computing resembles the pay- for- what -you -use model. It permits you to use as much resources as you need and pay only for that similar to electricity and water consumption, thus it is sometimes referred as utility computing.

IAAS: In this service the user is provided by virtual servers and memory for storage. Through provider’s application program interface (API) users can access, control and operate their servers. This service is also called as utility service.

PAAS: This service provides set of software and development tools to their users. They develop applications on the provider’s platform over the internet. Here the provider’s can also access API’S, website portal or gateways or the software’s installed on the customer’s computer.

SAAS: This is a broad market where users are allowed only to use the applications directly. These applications can be web based email or applications like facebook and twitter .

There can be various types of clouds :

PUBLIC: The public cloud shares services with anyone on the internet. These services are available via the web applications on the internet and the users can use these services as and when they require on utility basis.

PRIVATE: The private cloud shares the services to only selected users. These cloud provide network and data centre for a limited number of customers.

HYBRID: The hybrid cloud consists of both the internal and external i.e. private or public services. It supports both the physical and virtual servers and routers to access the required services.

Cloud computing is growing with time as it does not need any capital investment for the infrastructure and hardware. Instead it just has to rent or subscribe for the softwares and services they require. The other benefits also include resource sharing, shared infrastructures and softwares as also access to a broad range of applications simultaneously.
Thus, with this service the upfront capital expenditure for the companies for the hardware, softwares and the services they utilise will eventually be very minimal as compared to current investments. Many companies like IBM, Google, Microsoft and Gartner are seeing potential in cloud computing to provide better interactive services between their clients and the services provided to them by the companies .

With the time proceeding ahead there are diverse alterations in technology. Take the web for instance; it has dwelled from Web 1.0 to Web 2.0 i.e. from just an informative web to a more interactive one. Tim Berners-Lee, has come up with Web 3.0 which is also known as ‘semantic web’.

Tim Berners-Lee expressed his views on Web 3.0, as his dream to merge all the links, data and the interactions between the web and users through an intelligent search which even the computer can read and relate to. After this you might have got the rough idea about Web 3.0. In layman terms, you can say it is an intelligent interface between the computers and the web.

As in Web 2.0 ,we can socially interact with the web, which can be addressed as a duplex communication where there is two ways interactivity to read and write, but this interaction is understood only by humans . This is not going to be the case with Web 3.0. The machines are going to be endued with intelligence so that it can read the Web as much as we humans can and give us a more precise and accurate search results. These search results will be a combination of artificial intelligence and semantic web which all together will form a database which gives the admittance to both the machines and the web to incur the information postulated.

Web 3.0 will embark much more than just social networking, collaboration of various websites, use and create applications. It will commence the era of intelligent search with versatile web applications . This will wreak a new platform for open sourced data and software sources via the application programming interfaces (API’s). But, this will increase the security risk. Thus, for Web 3.0 to come into existence is going to take a longer duration of time may be more than it took to bring the Web into existence.

In the recent era, Internet had become substantive than PC, more is the requirement to be updated and interactive with the outside world and get the overview of the recent scenario about the occurrences in the market rather than to make excel sheets on the PC. But till when will the invention of operating systems survive on windows…? Will there be any other platform available..? The answer to all these questions is YES.

On the platform of cloud computing and .NET Microsoft is working on presenting the second era in operating systems by designing a non-window based OS , “MIDORI”.

Microsoft has not openly given any details regarding Midori, but has surely accepted that it exists. Midori is expected to work on the footprints of cloud computing and singularity. A totally new concept ‘Singularity’ is based on high reliability and which will offer a new platform for Midori to boom. Singularity possesses three key components: the kernel, software isolated processes and channels.

The kernel is responsible for managing the memory, internal and external processes, scheduling. The kernel is written only 5% in the assembler or C, C++ and rest in any other language that contains #, like C#. These are then translated to Microsoft independent language (MSIL) which is processor independent instruction set of Microsoft Common Language Runtime (CLR) which is compiled in Microsoft research Bartok compiler. The languages with only #, are used as they offer more reliability from viruses, buffer overruns, exploitation by worms.

Software Isolated Processes have all the backup data and executing codes in case of any failure like a device driver or system process, this preventing the OS to come down. Two SIP’s cannot access the same object simultaneously and have different run time and different specified applications.

Channels are the way of communication between the SIP’s. These are bidirectional channels used for communication and provide more reliability.

Midori is supposed to work on hardware like ARM, x86 ,x64 . It is an attempt to make an contemporary OS which will configure with any type of hardware and will be available on the internet and work on virtual servers via cloud computing. These concepts will eliminate the dependency on the local hardware and applications for an OS. According to Brain Madden, a technology analyst we don’t need to natively install the OS on the PC. “Why do we need it? We have hypervisors everywhere” he said.

As cloud computing has introduced the service on demand concept, Internet centric OS do make sense. As this may help in over all connectivity of the systems and provide what all applications needed. As to eliminate the problems like application compatibility which are faced by the Vista users can also solved by this new OS by using Virtualization.
As we cannot say the time when MIDORI will be officially announced by Microsoft, but this will surely make an impact similar or more radiant than that when Windows was launched in 1985.
