Roomba 780: A less than 10cm tall robot

The Roomba 780 is a robotic vacuum cleaner that’s less than 10cm tall.
The Roomba is a series of  autonomous robotic vacuum cleaners sold by iRobot. Under normal operating conditions, it is able to navigate a living space and common obstacles while vacuuming the floor. Several updates and new models have since been released that allow the Roombas to better negotiate obstacles and optimize cleaning.
The Roomba was introduced in 2002 As of February 2011, iRobot claims that over 6 million units have been sold.

The Roomba features a set of basic sensors that allow it to prevent itself from falling down stairs, change its direction when it bumps into an obstacle, and detect exceptionally dirty spots on the floor. It has two motorized wheels that can operate independently from each other. The Roomba uses the wheels to move forward and turn around its own axis to go in another direction.

Apple icar

An Apple board member has revealed that Steve Jobs had dreamed of creating an iCar before his  death.Italy based auto designer Liviu Tudoran has taken cues from the Apple products and designed a concept car called iMove for the year 2020.

His three-seater iMove plug-in electric concept car features loads of Apple-inspired gadgetry including a “photocromic” exterior that allows the driver to change the colour of the car, a touch-screen display that covers the entire dashboard (charged by solar receptors in the glass), and a convertible roof that can open up and has been designed to resemble the Apple mouse

Internet Freedom Fighters Build a Shadow Web

Governments and corporations have more control over the Internet than ever. Now digital activists want to build an alternative network that can never be blocked, filtered or shut down.

 

Just after midnight on January 28, 2011, the government of Egypt, rocked by three straight days of massive antiregime protests organized in part through Facebook and other online social networks, did something unprecedented in the history of 21st-century telecommunications: it turned off the Internet. Exactly how it did this remains unclear, but the evidence suggests that five well-placed phone calls—one to each of the country’s biggest Internet service providers (ISPs)—may have been all it took. At 12:12 a.m. Cairo time, network routing records show, the leading ISP, Telecom Egypt, began shutting down its customers’ connections to the rest of the Internet, and in the course of the next 13 minutes, four other providers followed suit. By 12:40 a.m. the operation was complete. An estimated 93 percent of the Egyptian Internet was now unreachable. When the sun rose the next morning, the protesters made their way to Tahrir Square in almost total digital darkness.

Both strategically and tactically, the Internet blackout accomplished little—the crowds that day were the biggest yet, and in the end, the demonstrators prevailed. But as an object lesson in the Internet’s vulnerability to top-down control, the shutdown was alarmingly instructive and perhaps long overdue.

 

 

  brief description:-

• The Internet was designed to be a decentralized system: every node should connect to many others. This design helped to make the system resistant to censorship or outside attack.

• Yet in practice, most individual users exist at the edges of the network, connected to others only through their Internet service provider (ISP). Block this link, and Internet access disappears.

• An alternative option is beginning to emerge in the form of wireless mesh networks, simple systems that connect end users to one another and automatically route around blocks and censors.

• Yet any mesh network needs to hit a critical mass of users before it functions well; developers must convince potential users to trade off ease of use for added freedom and privacy.

Could the Internet Ever Be Destroyed?

The coming threats to the global Internet could take many forms

 

The raging battle over SOPA and PIPA, the proposed anti-piracy laws, is looking more and more likely to end in favor of Internet freedom — but it won't be the last battle of its kind. Although, ethereal as it is, the Internet seems destined to survive in some form or another, experts warn that there are many threats to its status quo existence, and there is much about it that could be ruined or lost.

Physical destruction

A vast behemoth that can route around outages and self-heal, the Internet has grown physically invulnerable to destruction by bombs, fires or natural disasters — within countries, at least. It's "very richly interconnected," said David Clark, a computer scientist at MIT who was a leader in the development of the Internet during the 1970s. "You would have to work real hard to find a small number of places where you could seriously disrupt connectivity." On 9/11, for example, the destruction of the major switching center in south Manhattan disrupted service locally. But service was restored about 15 minutes later when the center "healed" as the built-in protocols routed users and information around the outage.

However, while it's essentially impossible to cripple connectivity internally in a country, Clark said it is conceivable that one country could block another's access to its share of the Internet cloud; this could be done by severing the actual cables that carry Internet data between the two countries. Thousands of miles of undersea fiber-optic cables that convey data from continent to continent rise out of the ocean in only a few dozen locations, branching out from those hubs to connect to millions of computers. But if someone were to blow up one of these hubs — the station in Miami, for example, which handles some 90 percent of the Internet traffic between North America and Latin America — the Internet connection between the two would be severely hampered until the infrastructure was repaired.

Such a move would be "an act of cyberwar," Clark told Life's Little Mysteries, a sister site to LiveScience.

Content cache

Even an extreme disruption of international connectivity would not seriously threaten the survival of Web content itself. A "hard" copy of most data is stored in nonvolatile memory, which sticks around with or without power, and whether you have Internet access to it or not. Furthermore, according to William Lehr, an MIT economist who studies the economics and regulatory policy of the Internet-infrastructure industries, the corporate data centers that harbor Web content — everything from your emails to this article — have sophisticated ways to back up and diversely store the data, including simply storing copies in multiple locations.

Google even stores cached copies of all Wikipedia pages; these were accessible on Jan. 18 when Wikipedia took its own versions of the pages offline in protest of SOPA and PIPA.

This diversified storage plan keeps the content itself safe, but it also offers some protection against loss of access to any one copy of the data in the event of a cyberwar. For example, if power were cut to a server, you may be unable to reach a website on its home server, but you mayfind a cached version of the content stored on another, accessible server. Or, "If you wanted data that was not available from a server in country X, you may be able to get substantively the same data from a server in country Y," Lehr said.

Internet arms race

The redundancy of so much online content and of connectivity routes makes the Internet resilient to physical attacks, but a much more serious threat to its status quo existence is government regulation or censorship. In the early days of Egypt's Arab Spring uprising, the government of Hosni Mubarak attempted to shut down the country's Internet in order to cripple protesters' ability to organize; it did this by ordering the state-controlled Internet Service Provider (ISP), which grants Internet access to customers, to cut service.

Intel first Smartphone "Xolo X900" Lands in India

Intel and Lava International are launching the first smartphone powered by one of the chip maker's Atom processors next week in India. The 3G-enabled Xolo X900 running Android will go on sale in the country on April 23 and cost 22,000 Indian rupees, or about $425, without a cellphone plan, Lava announced Thursday.

The phone is based on a reference design developed by Intel and uses a Medfield-class System-on-a-Chip (SoC), the Atom Z2460, which combines a single-core, hypterthreading-enabled 1.6GHz central processor with a 400MHz graphics core and a wireless networking radio. Intel and India-based Lava announced a technology partnership at the Mobile World Congress in February.

The Xolo X900 has a 4.03-inch LCD capacitive multi-touch screen with 1024-by-600 resolution and protected by Corning Gorilla Glass, dedicated HDMI output, full HD 1080p playback, and dual speakers, as well as an 8-megapixel rear camera and a 1.3-megapixel front-facing camera.

The only available model has 16GB of internal storage and 1GB of RAM, according to the tech specs posted on Lava's dedicated Xolo X900 website.

The Intel-based smartphone runs Google's Android 2.3 Gingerbread OS but is upgradeable to Android 4.0 Ice Cream Sandwich, according to the phone manufacturer.

Intel has struggled to penetrate an exploding mobile device market that largely relies on processors using the ARM instruction set instead of the chip giant's x86-based products which have long dominated larger computing platforms like desktops and laptops. But the company has been adamant in pronouncing that 2012 is the year that Intel-based smartphones will finally take off.

Medfield, Intel's fourth-generation platform for what the company calls mobile Internet devices (MIDs), is tipped to be the first Atom SoC with the combination of processing strengths, wireless networking, and a low enough power draw to make it an alternative to ARM chips for smartphones and other mobile devices.

"We finally have a very competitive product for smartphones," Jeff Ross, director of Intel's Marketing for Mobile and Communications Group, told Wired this week. "We have a high-performance part that can compete with products in the market, and those coming out to the market. It's not just about the performance, but also about the energy efficiency. There are number of performance factors that we'll be the best at."

Intel has also partnered with Motorola, Lenovo, Orange, and ZTE on Atom-based smartphones that are expected to be released in various markets in the coming months.

TCS planning to hire 50,000 in FY13

MUMBAI: Software major Tata Consultancy Services(TCS) today said it is planning to hire 50,000 people in FY 13.

"TCS is well prepared to achieve balanced growth across industries and markets it operates in FY 13. In view of good momentum, we are targeting to hire 50,000 people this year," TCS CEO and MD N Chandrasekaran told reporters here.

In view of excellent growth in North American and UK markets, we will continue hiring in the overseas markets, he said.

"We are hiring employees in the USA, including trainees. We will be visiting campuses in the USA during the fall semester," Executive Vice President, Head, Global Human Resources Ajoy Mukherjee said.

Commenting on wage hike, Chandrasekaran said the company has gone ahead with wage increase and employees will get hike of 8 percent on an average depending on their grades.

He also said that though there is a dip in volume growth in Europe, this is expected to pick up in the next quarter. The company had successfully undertaken the largest ever hiring effort in its history by adding and integrating 70,400 professionals during 2011-12.

"With business demand continuing to be robust, we have made 43,600 offers on campuses for trainees to join us from the second quarter of this fiscal year. Our efforts to increase retention by engaging with our employees and offering them a progressive career path are paying dividends with attrition rates falling further to 12.2 per cent," Mukherjee said.

The company has maintained high utilisation rates in the fourth quarter with utilisation excluding trainees at 80.6 per cent, while utilisation including trainees was at 71.3 per cent. The overall attrition rate was lower at 12.2 percent with IT attrition at a low of 11.05 per cent and BPO attrition at 21.6 percent.

The average age of a TCS employee is 28 yrs and 62.4 percent of the workforce has more than 3 yrs experience while 31.6 percent of the workforce comprised of women.
