Pedophiles can exploit virus-infected PCs to remotely store and view their stash without fear they'll get caught. Pranksters or someone trying to frame you can tap viruses to make it appear that you surf illegal Web sites.

Whatever the motivation, you get child porn on your computer — and might not realize it until police knock at your door.

In 2007, Fiola's bosses became suspicious after the Internet bill for his state-issued laptop showed that he used 4 1/2 times more data than his colleagues. A technician found child porn in the PC folder that stores images viewed online. Fiola was fired and charged with possession of child pornography, which carries up to five years in prison. He endured death threats, his car tires were slashed and he was shunned by friends. Fiola and his wife fought the case, spending $250,000 on legal fees. They liquidated their savings, took a second mortgage and sold their car. An inspection for his defense revealed the laptop was severely infected. It was programmed to visit as many as 40 child porn sites per minute — an inhuman feat. While Fiola and his wife were out to dinner one night, someone logged on to the computer and porn flowed in for an hour and a half. Prosecutors performed another test and confirmed the defense findings. The charge was dropped — 11 months after it was filed.

A year ago, exciting news about publishing 2.0 reached the blogosphere. Thriller writer Paulo Coelho had started to tell people how he was using filesharing networks as a way to promote his books. Coelho thinks that giving people the possibility to swap his books for free, actually has a positive effect on sales. In a keynote speech at the Digital, Life, Design conference in Munich he gave some strikingly good examples. When he uploaded the Russian translation of “The Alchemist”, sales in Russia went from around a 1.000 books per year to 100.000 and then to a million and more

His American publisher wasn’t too pleased though. After a rather imitating call from CEO Jane Friedman, Coelho chose a middle way and made the book viewable – but not downloadable. The torrent links are still up there though. Why? Coelho: “You’ll have to share in order to get some revenue”.

“At the end of the day, it doesn’t hurt your sales. People download the book but don’t read it They wait for the hard copy anyway”, Coelho continued. “Don’t be fooled by the publishers who say that piracy costs authors money.”

ACTIVISTS claimed on Tuesday to have seized control of nearly 300 Facebook community groups in a self-proclaimed effort to expose how vulnerable online reputations are to tampering.

CYI claimed its motives were pure and that the move was more of a 'take-over' than a computer hack of Facebook groups.

'Facebook Groups suffer from a major flaw,' said a message on the CYI blog. 'If an administrator of a group leaves, anyone can register as a new admin. So, in order to take control of a Facebook group, all you really have to do is a quick search on Google.' Once CYI accessed groups as administrators it had authority to change anything, including pictures, descriptions and settings.

On the benefit side, people become more engaged when they can filter information that is presented visually and make discoveries on their own. On the risk side, Professor Shneiderman says, tools as powerful as visualizations have the potential to mislead or confuse consumers. And privacy implications arise, he says, as increasing amounts of personal, housing, medical and financial data become widely accessible, searchable and viewable.

In the 1990s, Professor Shneiderman developed tree mapping, which uses interlocking rectangles to represent complicated data sets. The rectangles are sized and colored to convey different kinds of information, like revenue or geographic region, says Jim Bartoo, the chief executive of the Hive Group, a software company that uses tree mapping to help companies and government agencies monitor operational data. When executives or plant managers see the nested rectangles grouped together, he adds, they should be able to immediately spot anomalies or trends. In one tree-map visualization of a sales department on the Hive Group site, red tiles represent underperforming sales representatives while green tiles represent people who exceeded their sales quotas. So it’s easy to identify the best sales rep in the company: the biggest green tile. But viewers can also reorganize the display — by region, say, or by sales manager — to see whether patterns exist that explain why some employees are falling behind. “It’s the ability of the human brain to pick out size and color” that makes tree mapping so intuitive, Mr. Bartoo says. Information visualization, he adds, “suddenly starts answering questions that you didn’t know you had.”

data visualization is no longer just a useful tool for researchers and corporations. It’s also an entertainment and marketing vehicle.

people often lose sight of security concerns amid the collective euphoria that can accompany swift, large-scale democratization movements like the ones in Egypt and Tunisia. “The eye gets focused on the goal and not the process,” he said, “and during that time, they put their own personal security and their network security at risk.”

But it’s not just the fog of enthusiasm that renders people vulnerable; it’s lack of experience.

Those dangers have become increasingly apparent in recent months. Facebook accounts were hacked in Tunisia. In Egypt, authorities shut down the Internet and cellphones, and employed technology that turned mobile phones into furtive listening devices, according to the guide.

To the global warming deniers, Muller had been an important scientific figure with good credentials who had expressed doubt about the temperature data used to track the last few decades of global warming. Muller was influenced by Anthony Watts, a former TV weatherman (not a trained climate scientist) and blogger who has argued that the data set is mostly from large cities, where the “urban heat island” effect might bias the overall pool of worldwide temperature data. Climate scientists have pointed out that they have accounted for this possible effect already, but Watts and Muller were unconvinced. With $150,000 (25% of their funding) from the Koch brothers (the nation’s largest supporters of climate denial research), as well as the Getty Foundation (their wealth largely based on oil money) and other funding sources, Muller set out to reanalyze all the temperature data by setting up the Berkeley Earth Surface Temperature Project.

Although only 2% of the data were analyzed by last month, the Republican climate deniers in Congress called him to testify in their March 31 hearing to attack global warming science, expecting him to give them scientific data supporting their biases. To their dismay, Muller behaved like a real scientist and not an ideologue—he followed his data and told them the truth, not what they wanted to hear. Muller pointed out that his analysis of the data set almost exactly tracked what the National Oceanographic and Atmospheric Administration (NOAA), the Goddard Institute of Space Science (GISS), and the Hadley Climate Research Unit at the University of East Anglia in the UK had already published (see figure).

Muller testified before the House Committee that: The Berkeley Earth Surface Temperature project was created to make the best possible estimate of global temperature change using as complete a record of measurements as possible and by applying novel methods for the estimation and elimination of systematic biases. We see a global warming trend that is very similar to that previously reported by the other groups. The world temperature data has sufficient integrity to be used to determine global temperature trends. Despite potential biases in the data, methods of analysis can be used to reduce bias effects well enough to enable us to measure long-term Earth temperature changes. Data integrity is adequate. Based on our initial work at Berkeley Earth, I believe that some of the most worrisome biases are less of a problem than I had previously thought.

This was not a statistically controlled study: the subjects took a free test online and of their own accord.  They were by definition connected to the internet and interested in testing their English; they will also be younger and more urban than the population at large.

But Philip Hult, the boss of EF, says that his sample shows results similar to a more scientifically controlled but smaller study by the British Council.

Wealthy countries do better overall. But smaller wealthy countries do better still: the larger the number of speakers of a country’s main language, the worse that country tends to be at English. This is one reason Scandinavians do so well: what use is Swedish outside Sweden?  It may also explain why Spain was the worst performer in western Europe, and why Latin America was the worst-performing region: Spanish’s role as an international language in a big region dampens incentives to learn English.

I have been intrigued by an essay by my colleague Michael Ruse, entitled “Evolution and the idea of social progress,” published in a collection that I am reviewing, Biology and Ideology from Descartes to Dawkins (gotta love the title!), edited by Denis Alexander and Ronald Numbers.

Ruse's essay in the Alexander-Numbers collection questions the received story about the early evolution of evolutionary theory, which sees the stuff that immediately preceded Darwin — from Lamarck to Erasmus Darwin — as protoscience, the immature version of the full fledged science that biology became after Chuck's publication of the Origin of Species. Instead, Ruse thinks that pre-Darwinian evolutionists really engaged in pseudoscience, and that it took a very conscious and precise effort on Darwin’s part to sweep away all the garbage and establish a discipline with empirical and theoretical content analogous to that of the chemistry and physics of the time.

Ruse’s somewhat surprising yet intriguing claim is that “before Charles Darwin, evolution was an epiphenomenon of the ideology of [social] progress, a pseudoscience and seen as such. Liked by some for that very reason, despised by others for that very reason.”

better management of flood risks in Australia will depend up better data on flood risk.  However, collecting such data has proven problematic

As many Queenslanders affected by January’s floods are realising, riverine flood damage is commonly excluded from household insurance policies. And this is unlikely to change until councils – especially in Queensland – stop dragging their feet and actively assist in developing comprehensive data insurance companies can use.

? Because there is often little available information that would allow an insurer to adequately price this flood risk. Without this, there is little economic incentive for insurers to accept this risk. It would be irresponsible for insurers to cover riverine flood without quantifying and pricing the risk accordingly.

The study’s authors argue that removing age restrictions from sites like Facebook might actually be the best way of improving child safety online.

Elisabeth Staksrud, from the University of Oslo and one of the report’s authors comments that: “since children often lie about their age to join ‘forbidden’ sites it would be more practical to identify younger users and to target them with protective measures.”

This flies in the face of what many see as a critical security wall  protecting children from cyber-crime on social networking sites. A report released in January by Internet security firm PandaLabs identified Facebook and Twitter as the sites which are most prone to security breaches. The danger is particularly accute when young children enter their real personal information on their profile. Though, as the new research indicates, children are already lying about their age to sign up for a profile. So from a safety standpoint, the most important measure for children to take is to refrain from entering real information such as their address or where they go to school.

debates about the nature, the architecture and the governing principles of the internet are not merely technical or economic discussions.  Above all, these debates have deep political, social, and cultural implications and become a matter of public, national and global interest.

In many ways, net neutrality could be considered the first amendment of the internet; no pun intended here. However, just as with freedom of speech the principle of net neutrality cannot be approached as absolute or as a fetish. Even in a democracy we cannot say everything applies all the time in all contexts. Limiting the core principle of freedom of speech in a democracy is only possible in very specific circumstances, such as harm, racism or in view of the public interest. Along the same lines, compromising on the principle of net neutrality should be for very specific and clearly defined reasons that are transparent and do not serve commercial private interests, but rather public interests or are implemented in view of guaranteeing an excellent quality of service for all.

One of the only really convincing arguments of those challenging net neutrality is that due to the dramatic increases in streaming activity and data-exchange through peer-to-peer networks, the overall quality of service risks being compromised if we stick to data being treated on a first come first serve basis. We are being told that popular content will need to be stored closer to the consumer, which evidently comes at an extra cost.

That is nothing, though, compared with the attack by Temasek Review, the anonymously-run website with lofty ambitions “to foster an informed, educated, thinking and proactive citizenry.” The website delved into her personal life – even questioning her motives for marrying her husband – to present her as a materialistic, social climbing monster. Such attacks have also been flying around social media.

Never mind that Tin (unlike most high-flying PAP candidates) has several years’ grassroots experience; sections of the online community have dismissed the possibility that someone so young – she is in her 20s – could serve in the highest forum in the land. (I recall feeling similarly skeptical when Eunice Olsen was put up as an NMP. She proved me wrong and I have learnt not to prejudge.)

Siew Kum Hong, hardly a PAP apologist, has had the intellectual honesty and moral courage to come out swiftly in his blog against this distasteful turn of events.
