IBM Breaks Big Data Record
IBM Labs claims to have broken a speed record for Big Data, which the company says could help boost internet speeds to 200 to 400Gbps using “extremely low power”.
The scientists achieved the speed record using a prototype device presented at the International Solid-State Circuits Conference (ISSCC) this week in San Francisco.
Apparently the device, which employs analogue-to-digital conversion (ADC) technology, could be used to improve the transfer speed of Big Data between clouds and data centres to four times faster than existing technology.
IBM said its device is fast enough that 160GB – the equivalent of a two-hour 4K ultra-high definition (UHD) movie or 40,000 music tracks – could be downloaded in a few seconds.
The IBM researchers have been developing the technology in collaboration with Swiss research institution Ecole Polytechnique Fédérale de Lausanne (EPFL) to tackle the growing demands of global data traffic.
“As Big Data and internet traffic continues to grow exponentially, future networking standards have to support higher data rates,” the IBM researchers explained, comparing data transfer per day in 1992 of 100GB to today’s two Exabytes per day, a 20 million-fold increase.
“To support the increase in traffic, ultra-fast and energy efficient analogue-to-digital converter (ADC) technology [will] enable complex digital equalisation across long-distance fibre channels.”
An ADC device converts analogue signals to digital, estimating the right combination of zeros and ones to digitally represent the data so it can be stored on computers and analysed for patterns and predictive outcomes.
“For example, scientists will use hundreds of thousands of ADCs to convert the analogue radio signals that originate from the Big Bang 13 billion years ago to digital,” IBM said.
The ADC technology has been developed as part of an international project called Dome, a collaboration between the Netherlands Institute for Radio Astronomy (ASTRON), DOME-South Africa and IBM to build the Square Kilometer Array (SKA), which will be the world’s largest and most sensitive radio telescope when it’s completed.
“The radio data that the SKA collects from deep space is expected to produce 10 times the global internet traffic and the prototype ADC would be an ideal candidate to transport the signals fast and at very low power – a critical requirement considering the thousands of antennas which will be spread over 1,900 miles,” IBM expalined.
IBM Research Systems department manager Dr Martin Schmatz said, “Our ADC supports Institute of Electrical and Electronics Engineers (IEEE) standards for data communication and brings together speed and energy efficiency at 32 nanometers, enabling us to start tackling the largest Big Data applications.”
He said that IBM is developing the technology for its own family of products, ranging from optical and wireline communications to advanced radar systems.
“We are bringing our previous generation of the ADC to market less than 12 months since it was first developed and tested,” Schmatz added, noting that the firm will develop the technology in communications systems such as 400Gbps opticals and advanced radars.
Techies Demand More Money

Employers may need to loosen their purse strings to retain their IT staffers in 2014, according to a salary survey from IT career websiteDice.com.
Among the tech workers who anticipate changing employers in 2014, 68 percent listed more compensation as their reason for leaving. Other factors include improved working conditions (48 percent), more responsibility (35 percent) and the possibility of losing their job (20 percent). The poll, conducted online between Oct. 14 and Nov. 29 last year, surveyed 17,236 tech professionals.
Fifty-four percent of the workers polled weren’t content with their compensation. This figure is down from 2012′s survey, when 57 percent of respondents were displeased with their pay.
The decrease in salary satisfaction could mean companies will face IT staff retention challenges this year, since 65 percent of respondents said they’re confident they can find a new, better position in 2014.
This dissatisfaction over pay comes even though the survey, released Wednesday, showed that the average tech salary rose 2.6 percent in 2013 to US$87,811 and that more companies gave merit raises. The main reason for last year’s bump in pay, according to 45 percent of respondents, was a merit raise. In comparison, the average tech salary was $85,619 in 2012 and 40 percent of those polled said they received a merit raise.
Meanwhile, 26 percent of respondents attributed their 2013 salary increase to taking a higher-paying job at another company.
Employers realize tech talent is coveted and are attempting to keep workers satisfied by offering them a variety of incentives, the survey found. In 2013, 66 percent of employers provided incentives to retain workers. The two most popular incentives were increased compensation and more interesting work. Incentives that allow employees to better balance their work and personal lives were also offered, such as telecommuting and a flexible work schedule.
Skills that commanded six-figure jobs in 2013 came from some of the hottest areas of IT. Data science led the way with big data backgrounds yielding some of the highest salaries. People skilled in Knowing R, the popular statistical computing language, can expect to make $115,531 on average, while those with NoSQL database development skills command an average salary of $114,796. IT pros skilled in MapReduce to process large data sets make $114,396 on average.
NSA Spies With Tracking Cookies

Comments Off on NSA Spies With Tracking Cookies
The browser cookies that online businesses use to track Internet customers for targeted advertising are also used by the National Security Agency to track surveillance targets and break into their systems.
The agency’s use of browser cookies is restricted to tracking specific suspects rather than sifting through vast amounts of user data, theWashington Post reported Tuesday, citing internal documents obtained from former NSA contractor Edward Snowden.
Google’s PREF (for preference) cookies, which the company uses to personalize webpages for Internet users based on their previous browsing habits and preferences, appears to be a particular favorite of the NSA, the Post noted.
PREF cookies don’t store any user identifying information such as user name or email address. But they contain information on a user’s general location, language preference, search engine settings, number of search results to display per page and other data that lets advertisers uniquely identify an individual’s browser.
The Google cookie, and those used by other online companies, can be used by the NSA to track a target user’s browsing habits and to enable remote exploitation of their computers, the Post said.
Documents made available by Snowden do not describe the specific exploits used by the NSA to break into a surveillance target’s computers. Neither do they say how the NSA gains access to the tracking cookies, the Post reported.
It is theorized that one way the NSA could get access to the tracking cookies is to simply ask the companies for them under the authority granted to the agency by the Foreign Intelligence Surveillance Act (FISA).
Separately, the documents leaked by Snowden show that the NSA is also tapping into cell-phone location data gathered and transmitted by makers of mobile applications and operating systems. Google and other Internet companies use the geo-location data transmitted by mobile apps and operating systems to deliver location-aware advertisements and services to mobile users.
However, the NSA is using the same data to track surveillance targets with more precision than was possible with data gathered directly from wireless carriers, the Post noted. The mobile app data, gathered by the NSA under a program codenamed “Happyfoot,” allows the agency to tie Internet addresses to physical locations more precisely than was possible with cell-phone location data.
An NSA division called Tailored Access Operations uses the data gathered from tracking cookies and mobile applications to launch offensive hacking operations against specific target computers, the Post said.
An NSA spokeswoman Wednesday did not comment on the specific details in the Post story but reiterated the agency’s commitment to fulfill its mission of protecting the country against those seeking to do it harm.
“As we’ve said before, NSA, within its lawful mission to collect foreign intelligence to protect the United States, uses intelligence tools to understand the intent of foreign adversaries and prevent them from bringing harm to innocent Americans and allies,” the spokeswoman said.
The Post’s latest revelations are likely to shine a much-needed spotlight on the extensive tracking and monitoring activities carried out by major Internet companies in order to deliver targeted advertisements to users.
Privacy rights groups have protested such tracking for several years and have sought legislation that would give users more visibility and control over the data that is collected on them by online companies.
