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

How Controlling Robots With Your Thoughts



Over recent months, in José del R. Millán’s computer science lab in Switzerland, a little round robot, similar to a Roomba with a laptop mounted on it (right), bumped its way through an office space filled with furniture and people. Nothing special, except the robot was being controlled from a clinic more than 60 miles away—and not with a joystick or keyboard, but with the brain waves of a paralyzed patient.
The robot’s journey was an experiment in shared control, a type of brain-machine interface that merges conscious thought and algorithms to give disabled patients finer mental control over devices that help them communicate or retrieve objects. If the user experiences a mental misfire, Millán’s software can step in to help. Instead of crashing down the stairs, for instance, the robot would recalculate to find the door.
Such technology is a potential life changer for the tens of thousands of people suffering from locked-in syndrome, a type of paralysis that leaves patients with only the ability to blink. The condition is usually incurable, but Millán’s research could make it more bearable, allowing patients to engage the world through a robotic proxy. “The last 10 years have been like a proof of concept,” says Justin Sanchez, director of the Neuro­prosthetics Research Group at the University of Miami, who is also studying shared control. “But the research is moving fast. Now there is a big push to get these devices to people who need them for everyday life.”

How Robots Invent Their Own Language


Australian scientists have invented a new breed of robots called Lingodroids, programmed to make, use, and share language. The bots can coin words to describe places they have been, places they want to go, and plans for getting there. “When they need a new word, they invent one,” says , a cognitive scientist at the University of Queensland who leads an interdisciplinary team on the project.
The rolling chatterboxes “see” using 360-degree cameras, laser range finders, and sonar. A microphone functions as their ears, and a speaker acts as a voice box, emitting the familiar beeps of a touch-tone phone. As for brains, Wiles outfitted each Lingodroid with an alphabet of beeps that correspond to letters. Then she programmed them to play a series of games in which they paired the letters into nonsensical combinations like “ja” or “ku” and joined those syllables to coin neologisms as needed. For example, in one game two robots roamed through a course and met in an unfamiliar part of it. The meeting triggered one robot to name the spot “jaya” and share the new word with its partner, who then added the word to its lexicon. In this way the robots slowly built a new language to describe their travels [pdf] and eventually even learned to communicate and understand directions.
Wiles notes that although the language may seem simple, for robots, grasping spatial information is incredibly complex. “We don’t realize how sophisticated our use of language to describe the world around us is,” she says. Ultimately, she hopes to teach her robots to chat up humans, paving the way for robotic caregivers, companions, and butlers

India asks U.S. to remove objectionable content from Facebook, YouTube


The Indian government has asked the US to ensure that India-specific objectionable content are removed from the social networking such as Facebook, Google and YouTube. The government also wants these service providers to set up servers in India to order to regulate the content locally.
According to a Hindustan Times report, India conveyed its concerns to visiting S deputy secretary for homeland security Jane Holl Lute. The visiting envoy was told that the U.S. should have an operating procedure that will help authorities to remove the objectionable content within a specific time period or instantaneously depending upon the situation.
It's learnt that this is not the first time the Indian government had made attempts to regulator content via a local server. Earlier this year, Research in Motion (RIM) set up an India dedicated server, allowing the government full access to messages from BlackBerry’s popular messaging service BBM. The government has previously made attempts to get access to Yahoo and gmail chatting/e-mails.
The development comes at a time when the Internet companies are locked in a web censorship. Social sites such as Facebook are facing trial in India for allegedly hosting objectionable content. A Delhi court ordered  issuing summons to Facebook via e-mail after the U.S-based social networking company didn't show up in the court despite several summons issued against it. Read our full coverage on web censorship row here.

speed up your PC using multiple chips


Having reached their peak potential, computer chips are not getting any faster. So chipmakers are configuring additional cores or processing units on a single platform in order to skirt this problem.

Today, a typical chip might have six or eight cores, all communicating with one another over a single bundle of wires, called a bus. With a bus, however, only one pair of cores can talk at a time, which would be a serious limitation in chips with hundreds or even thousands of cores, envisioned as the future of computing.

Li-Shiuan Peh, associate professor of electrical engineering and computer science at MIT, wants cores to communicate the same way computers hooked to the Internet do: by bundling the information they transmit into "packets".

Each core would have its own router, which could send a packet down any of several paths, depending on the condition of the network as a whole. Multicore chips are faster than single-core chips because they can split up computational tasks and run them on several cores at once, according to an MIT statement.

Cores working on the same task will occasionally need to share data but, until recently, the core count on commercial chips has been low enough that a single bus has been able to handle the extra communication load.

That's already changing, however. "Buses have hit a limit," Peh says. "They typically scale to about eight cores." The 10-core chips found in high-end servers frequently add a second bus, but that approach won't work for chips with hundreds of cores.

Peh and colleagues have developed two techniques to address these concerns. One is something they call "virtual bypassing". In the net, when a packet arrives at a router, the router inspects its addressing information before deciding which path to send it down.

With virtual bypassing, however, each router sends an advance signal to the next, so that it can preset its switch, speeding the packet on with no additional computation. In her group's test chips, Peh says, virtual bypassing allowed a very close approach to the maximum data-transmission rates predicted by theoretical analysis.

These findings will be presented at the Design Automation Conference in June in the US.

How Wireless device turns iPhone into remote controller

 Thiru Arunachalam and Bala Krishnan have turned your iPhone into a TV remote. Peel, their startup in downtown Mountain View, hopes to 'peel' off the layers of complexities associated with today's TV viewing.

All you need is your television set, an Apple device -- an iPhone or even an iPod Touch -- a wireless router called Peel Fruit -- an odd-looking infrared blaster -- and the Peel cable which links directly to your home WiFi router's open ethernet port.

The Peel uses both WiFi and ZigBee, a wireless protocol technology, for connectivity and therefore, must be placed within 25 feet of each other. The Peel Fruit does all the talking to your TV and thus sits near the TV set. Then download the free Peel application from the App Store and your iPhone turns into your tele-remote.

But for the Peel experience, you must feed in the kind of shows -- or even genres -- that you like. And Peel 'discovers' the kind of shows you would like, eliminating the rest of the massive clutter.

This is actually a blessing for US viewers who have to battle a cumbersome television guide, resembling a boring data sheet, and rummage through 500 or more channels to figure out what exactly could be interesting.

"We lead busy lives and have limited time to watch television. And yet, land up wasting so much of that time on discovering what to watch, and this is getting harder and harder. It is a complicated problem in the living room today," says Peel co-founder Bala Krishnan.

So, if you like teen dramas like 90210, Peel could recommend that you watch Gossip Girl or Glee as well. Then, it allows you to share what you are watching with your friends on Twitter and Facebook, adding to a socialised TV experience. Behind the social fabric though, Peel constantly makes algorithm-based recommendations based on what your friends watch.

In many ways what Peel is doing is similar to Netflix -- a paid subscription-based movie rental and online video streaming service -- and Pandora Radio, a Valley startup which revolutionised Internet radio in the US wherein you key in your preferences and get algorithm-based recommendations. Movies and music have already turned interactive.

TV, which has traditionally been an offline medium, is finally starting to catch up, thanks to websites like Hulu. Hulu provides ad-supported and on-demand streaming of popular TV shows and some movies. Networks like CBS and ABC are also granting access to current content online.

"When the world moves to online TV, then Peel will become incredibly more relevant and we will be able to make TVwatching a seamless experience," says Krishnan.

Think about it: how many of us watch TV while we are doing something simultaneously on our laptops, tablets or smartphones? This is why Peel heralds the next wave in television and perhaps the next phase of Web applications which blend virtual and social media with interactive, possibly offline, activities.

"Consumers are showing some desire to engage more deeply with TV content while it's still on, especially for specific genres like sports and hit shows with young consumers that use social networks heavily (for example the Glee Superfan experience)," says Sam Rosen, senior analyst, digital home (TV & Video Service) with ABI Research, a tech-focused research firm.

Peel has nearly 1.3 million users and since last month, many of them cheer or boo on social networks for their favourite American Idol contestants up to 400 times on each Wednesday. This fun interaction is also precious real-time feedback, which could be priceless for the show's owners, and a potential side business model for Peel.

Such applications which extend TV viewing experiences are called Second Screen Apps while the assortment of devices used in front of the TV are called Companion Devices. A whole bunch of companies, big and small, have entered the space catering to different tech areas.

Startups like Miso and GetGlue focus on the social experience. Content-owners too are providing show-focused social, interactive platforms like Disney Second Screen, National Football League Gameday and Glee Superfan.

Then, Roku and Boxee are adding apps to TV. No wonder behemoths like Google, Apple and Microsoft have entered the space. With its Kinect bundles for the XBox, Microsoft provides voice-controlled TV along with music and gaming.

"Peel is unique in its bundling of universal remote technology with a social application. In my opinion, it will take richer metadata or other forms of additional content for these apps to catch on as more than a niche class of product," says Rosen.

"The industry is on fire but consumers still have to catch up," says Arunachalam. Though company is yet to make money, investors are rooting for it with Peel raising $25 million in VC funding. It hopes to start making money through advertisements when it gets more users: it's goal is to get about 10 million users by year end.

With so much information about each of its users, Peel hopes it will be able to give them not just personalised TV, but personalised advertising too. So, if you are hunting for movies, ads of local theatres' movie listings could pop up. Or if you like the sitcom Friends, then an ad for a Friends DVD giftset could pop up. "There is a very fine line between creepiness and usefulness and we want to tilt more towards usefulness by offering value," says Krishnan.

This could also be the dawn of the next wave of advertising that tech experts expect to see very soon, wherein the TV you're wat ching also "wat ches" you.

Consequently, we could have Advertising as a Service ( AaaS). Peel's founders believe that in as soon as 18 months, India too, will be at the tipping point of falling into the same TV viewing problem as America.

"Viewers in India are constantly hitting their remote button looking for what's on," says Arunachalam. "The Indian opportunity is enormous but incredibly complex because there are programmes in so many languages," says Krishnan.
