BBC News - Web code weakness allows data dump on PCs - 0 views

  • The loophole exploits a feature of HTML 5 which defines how websites are made and what they can do.
  • Developer Feross Aboukhadijeh found the bug and set up a demo page that fills visitors' hard drives with pictures of cartoon cats. In one demo, Mr Aboukhadijeh managed to dump one gigabyte of data every 16 seconds onto a vulnerable Macbook. Clever code Most major browsers, Chrome, Internet Explorer, Opera and Safari, were found to be vulnerable to the bug, said Mr Aboukhadijeh. While most websites are currently built using version 4 of the Hyper Text Markup Language (HTML), that code is gradually being superseded by the newer version 5. One big change brought in with HTML 5 lets websites store more data locally on visitors' PCs. Safeguards built into the "local storage" specification should limit how much data can be stored. Different browsers allow different limits but all allow at least 2.5 megabytes to be stored. However, Mr Aboukhadijeh found a way round this cap by creating lots of temporary websites linked to the one a person actually visited. He found that each one of these associated sites was allowed to store up to the limit of data because browser makers had not written code to stop this happening. By endlessly creating new, linked websites the bug can be used to siphon huge amounts of data onto target PCs. Only Mozilla's Firefox capped storage at 5MB and was not vulnerable, he found. "Cleverly coded websites have effectively unlimited storage space on visitor's computers," wrote Mr Aboukhadijeh in a blogpost about the bug. Code to exploit the bug has been released by Mr Aboukhadijeh and he set up a website, called Filldisk that, on vulnerable PCs, dumps lots of images of cats on to the hard drive. So far, no malicious use of the exploits has been observed. In a bid to solve the problem, bug reports about the exploit have been filed with major browser makers.

Wearable robot lets internet users 'feel' physical contact - Telegraph - 0 views

  • Internet users will be able to reach out and hug one another thanks to a new wearable robotic device that creates the sensation of physical contact
  • The iFeel-IM device, created by Japan-based scientists, simulates sensations such as heart beats, hugging, stomach butterflies and spine tingles among those wearing it.
  • "We are steeped in computer-mediated communication - SMS, e-mail, Twitter, Instant Messaging, 3-D virtual worlds - but many people don't connect emotionally," he said."I am looking to create a deep immersive experience, not just a vibration in your shirt triggered by an SMS. Emotion is what give communication life."

  • The device is capable of distinguishing nine emotions including joy, fear, interest, guilt and anger with 90 per accuracy resulting in corresponding physical sensations such as squeezes and increased warmth in the user.While the technology would have enabled scientists to add a mechanism for sexual desire, the scientists opted against it to avoid distracting from its emotion-based focus.

BBC News - Children 'must know web limits' says Wales commissioner - 0 views

  • Adults must impose the necessary checks and balances to keep children safe online, says the children's commissioner for Wales.
  • "All children and young people don't seem much of a distinction between their online and offline lives,"
  • Mr Towler told BBC Radio Wales. "It's all just one thing and they get really excited by the opportunities the internet affords and sometimes parents get a little scared about that and worried about what their children are accessing." 'Crossing the road' Continue reading the main story “Start Quote They're all running around with handheld computers these days, they're not just on phones ” End Quote Keith Towler Children's commissioner Mr Towler said he talks to children in lots of different settings and they "still enjoy playing outside as much as they ever did". He said we need to recognise that the internet provides fantastic opportunities for education and learning and its making sure that children access that safely. He said that was a real challenge for parents and carers. "It's a bit like crossing the road, you try to teach your children the best way of crossing the road well. We need to teach our children the best way of using this fantastic resource. "I think too many parents are very very scared of the internet and because they're so scared they will say 'Oh I don't understand it'". Handheld computers The commissioner also praised Hwb, the virtual learning environment, which he said provides protection for children using the web in schools. Mr Towler said: "We've got to get parents and carers to recognise that children do operate in the digital world. They're all running around with handheld computers these days, they're not just on phones. "They can access whatever they want whenever they want and parents need to engage on that. " "We need to remember that children and young people are much more savvy than sometimes we think they are, and they are much more responsible than sometimes adults think they are so its not all doom and gloom. "What we need to do is put the right checks and balances in place and what children always want from parents and carers is to understand what the boundaries are, and that's our job to do that." Sangeet Bhullar, executive director of Wise Kids, added that the digital landscape was "evolving rapidly" and up-to-date data was needed on how children and young people in Wales related to it.

Amazon unpacked - FT.com - 0 views

  • February 8, 2013 12:30 pm Amazon unpacked By Sarah O’Connor The online giant is creating thousands of UK jobs, so why are some employees less than happy?
  • Between a sooty power station and a brown canal on the edge of a small English town, there is a building that seems as if it should be somewhere else. An enormous long blue box, it looks like a smear of summer sky on the damp industrial landscape. Inside, hundreds of people in orange vests are pushing trolleys around a space the size of nine football pitches, glancing down at the screens of their handheld satnav computers for directions on where to walk next and what to pick up when they get there. They do not dawdle – the devices in their hands are also measuring their productivity in real time. They might each walk between seven and 15 miles today. It is almost Christmas and the people working in this building, together with those in seven others like it across the country, are dispatching a truck filled with parcels every three minutes or so. Before they can go home at the end of their eight-hour shift, or go to the canteen for their 30-minute break, they must walk through a set of airport-style security scanners to prove they are not stealing anything. They also walk past a life-sized cardboard image of a cheery blonde woman in an orange vest. “This is the best job I have ever had!” says a speech bubble near her head.
  • If you could slice the world in half right here, you could read the history of this town called Rugeley in the layers. Below the ground are the shafts and tunnels of the coal mine that fed the power station and was once the local economy’s beating heart. Above the ground are the trolleys and computers of Amazon, the global online retailer that has taken its place. As online shopping explodes in Britain, helping to push traditional retailers such as HMV out of business, more and more jobs are moving from high-street shops into warehouses like this one. Under pressure from politicians and the public over its tax arrangements, Amazon has tried to stress how many jobs it is creating across the country at a time of economic malaise. The undisputed behemoth of the online retail world has invested more than £1bn in its UK operations and announced last year that it would open another three warehouses over the next two years and create 2,000 more permanent jobs. Amazon even had a quote from David Cameron, the prime minister, in its September press release. “This is great news, not only for those individuals who will find work, but for the UK economy,” he said.

  • Workers in Amazon’s warehouses – or “associates in Amazon’s fulfilment centres” as the company would put it – are divided into four main groups. There are the people on the “receive lines” and the “pack lines”: they either unpack, check and scan every product arriving from around the world, or they pack up customers’ orders at the other end of the process. Another group stows away suppliers’ products somewhere in the warehouse. They put things wherever there’s a free space – in Rugeley, there are inflatable palm trees next to milk frothers and protein powder next to kettles. Only Amazon’s vast computer brain knows where everything is, because the workers use their handheld computers to scan both the item they are stowing away and a barcode on the spot on the shelf where they put it. The last group, the “pickers”, push trolleys around and pick out customers’ orders from the aisles. Amazon’s software calculates the most efficient walking route to collect all the items to fill a trolley, and then simply directs the worker from one shelf space to the next via instructions on the screen of the handheld satnav device. Even with these efficient routes, there’s a lot of walking. One of the new Rugeley “pickers” lost almost half a stone in his first three shifts. “You’re sort of like a robot, but in human form,” said the Amazon manager. “It’s human automation, if you like.” Amazon recently bought a robot company, but says it still expects to keep plenty of humans around because they are so much better at coping with the vast array of differently shaped products the company sells.
  • The unassuming efficiency of these warehouses is what enables Amazon to put parcels on customers’ doorsteps so quickly, even when it is receiving 35 orders a second. Every warehouse has its own “continuous improvement manager” who uses “kaizen” techniques pioneered by Japanese car company Toyota to improve prod­uctivity. Marc Onetto, the senior vice-president of worldwide operations, told a business school class at the University of Virginia a few years ago: “We use a bunch of Japanese guys, they are not consultants, they are insultants, they are really not nice … They’re samurais, the real last samurais, the guys from the Toyota plants.” In Rugeley, the person with the kaizen job is a friendly, bald man called Matt Pedersen, who has a “black belt” in “Six Sigma”, the Motorola-developed method of operational improvement, most famously embraced by Jack Welch at General Electric. Every day, the managers in Rugeley take a “genba walk”, which roughly means “go to the place” in Japanese, Pedersen says as he accompanies the FT on a tour of the warehouse. “We go to the associates and find out what’s stopping them from performing today, how we can make their day better.” Some people also patrol the warehouse pushing tall little desks on wheels with laptops on them – they are “mobile problem solvers” looking for any hitches that could be slowing down the operation.
  • . . . What did the people of Rugeley make of all this? For many, it has been a culture shock. “The feedback we’re getting is it’s like being in a slave camp,” said Brian Garner, the dapper chairman of the Lea Hall Miners Welfare Centre and Social Club, still a popular drinking spot. One of the first complaints to spread through the town was that employees were getting blisters from the safety boots some were given to wear, which workers said were either too cheap or the wrong sizes. One former shop-floor manager, who did not want to be named, said he always told new workers to smear their bare feet with Vaseline. “Then put your socks on and your boots on, because I know for a fact these boots are going to rub and cause blisters and sores.” ©Ben RobertsAmazon workers in Rugeley process ordersOthers found the pressure intense. Several former workers said the handheld computers, which look like clunky scientific calculators with handles and big screens, gave them a real-time indication of whether they were running behind or ahead of their target and by how much. Managers could also send text messages to these devices to tell workers to speed up, they said. “People were constantly warned about talking to one another by the management, who were keen to eliminate any form of time-wasting,” one former worker added.
  • Watson said Amazon was supposed to send the council employment data every six months, but it had not done so. “We had no idea Amazon were going to be as indifferent to these issues as they have been, it’s come as a shock to us how intransigent they are,” he said. Inside the warehouse, Amazon employees wear blue badges and the workers supplied by the agencies wear green badges. In the most basic roles they perform the same tasks as each other for the same pay of £6.20 an hour or so (the minimum adult wage is £6.19), but the Amazon workers also receive a pension and shares. A former agency worker said the prospect of winning a blue badge, “like a carrot, was dangled constantly in front of us by management in return for meeting shift targets”. Amazon’s Darwinian culture comes from the top. Jeff Bezos, its chief executive, told Forbes magazine last year (when it named him “number one CEO in America”): “Our culture is friendly and intense, but if push comes to shove, we’ll settle for intense.”
  • Ransdtad said it supplied a number of clients with “onsite-flexible workforce solutions”. It added: “The number of workers required by these clients fluctuates in response to supply and demand. When demand for clients’ products or services is high (for example during the Christmas period) the Randstad partnership allows local people to benefit from short-term work on a temporary contract, to help supplement our clients’ permanent workforce and deliver against order requirements.” Certainly, not everyone in Rugeley is upset about Amazon. A group of workers having a pint on a picnic table outside The Colliers pub near the warehouse gates said they liked their jobs, albeit as their managers hovered nervously in the background. One young agency worker said he was earning about £220 a week, compared with the £54 he had been receiving in jobless benefits. He had bought a car and moved out of his mum’s house and into a rented flat with his girlfriend, who he had met at work. “I’m doing pretty well for myself,” he said with a shy grin. “There’s always opportunities to improve yourself there.” Across the table, an older man, wagging two fingers with a cigarette pinched between them, said slowly: “It gives you your pride back, that’s what it gives you. Your pride back.” Many in the town, however, have mixed feelings. They are grateful for the jobs Amazon has created but they are also sad and angry about the quality of them. Timothy Jones, a barrister and parish councillor, summed up the mood. “I very much want them to stay, but equally I would like some of the worst employment practices to end.”
  • For Watson, the big question is whether these new jobs can support sustainable economic growth. In Rugeley, it is hard not to look back to the coal mine for an example of how one big employer could transform a place. . . . The Lea Hall Colliery opened officially on a soggy Tuesday in July 1960. Miners and their families huddled under marquees to eat their packed lunches and when the first coal was wound to the surface, three bands played an overture specially written for the occasion. It was the first mine planned and sunk by the Coal Board, the body set up after the second world war to run Britain’s newly nationalised coal industry, and the Central Electricity Generating Board was building a coal-fired power station right next door. It was a defiant demonstration of confidence in coal at a time of increasing competition from oil. “King Coal is not yet dead, as many would have it, but is going to be with us for many years to come,” the regional secretary of the National Union of Mineworkers told the crowd.
  • Soon, miners from all over the country were swarming to the modern new mine. The Coal Board and the local council built housing estates and schools to cope with the exploding population. “Peartree estate was built for the Geordies, the Springfield estate was built for the Scots and the Welsh,” remembered Brian Garner, who helped to build the mine when he was 16. “It was unbelievable, it was buzzing in the town, there was that much money about then. I could leave my job at 10 o’clock in the morning and start at five past 10 on another.” On Friday and Saturday nights, the queue outside the Lea Hall Miners’ Welfare Centre and Social Club would wrap right around the building. Rugeley’s mine was soon the most productive in the country. It was a “young man’s pit” with all the latest machines and techniques, says Ken Edwards, who started there at 25 as an electrician. The work was still dirty and dangerous, though. In 1972, a local reporter took a tour. “All is silent except for the movement of conveyor belts which carry the coal and the murmur of the air pumps. The blackness is relieved only by narrow shafts of light coming from each person’s headlamp,” she wrote. It took her two days to remove the black dust from her nails, ears, nose and hair.
  • The good times didn’t last. By the time the pit closed, four days before Christmas in 1990, a spokesman for British Coal told Reuters it was losing £300,000 a week. More than 800 people lost jobs that paid the equivalent of between £380 and £900 a week in today’s money. The town council’s chairman tried desperately to say something reassuring. “It has come as such a shock,” he told the local paper. “[But] we have got to do what many have done and look for new areas, particularly information technology and high technology. We have a lot of expertise and a wonderful geographical spot. There’s no reason why it should be the end for Rugeley.” From behind her desk in Vision estate agents, all purple paint and fairy lights, Dawn Goodwin sucks the air in through her teeth at the mention of Amazon. “We all thought it was going to be the making of the town,” she says. She expected an influx of people, including well-to-do managers, looking to buy or rent houses. But she hasn’t had any extra business at all. People are cautious because they don’t know how long their agency jobs with Amazon will last, she says. One of her tenants, a single young woman, got a job there but lost it again after she became ill halfway through a shift. She struggled to pay her rent for three months while she waited for her jobseeker’s benefits to be reinstated. “It’s leaving a bad taste in everyone’s mouths,” Goodwin says with a frown. Even the little “Unit 9” café next to the Amazon warehouse hasn’t had a boost in trade. The women who run it reckon the employees don’t have enough time in their 30-minute break to get through security, come and eat something, and then go back in again.
  • In a cramped upstairs office at the Citizens Advice Bureau, Gillian Astbury and Angela Jones have turned to statistics to try to identify Amazon’s effect on the area. They haven’t had an increase in the number of people asking about employment problems or unfair dismissal, but nor has there been any improvement in the community’s problems with debt and homelessness. Their best guess is that people haven’t had enough sustained work to make much of a difference. Astbury says employment agencies are a “necessary evil”, but stresses it is hardly ideal for people to be bouncing in and out of temporary work, particularly when a job ends abruptly and they are left with no income at all until their benefits are reinstated. Workers leaving Amazon have had a particular problem with this, prompting the parish council to submit a Freedom of Information request to the Department for Work and Pensions to find out exactly how long local people are being made to wait for their social security payments to come through.
  • Far from the CAB’s little office in Rugeley, Britain’s economists are also puzzling over why the economy remains moribund even though more and more people are in work. There are still about half a million fewer people working as full-time employees than there were before the 2008 crash, but the number of people in some sort of employment has surpassed the previous peak. Economists think the rise in insecure temporary, self-employed and part-time work, while a testament to the British labour market’s flexibility, helps to explain why economic growth remains elusive. Angi Cooney, who runs C Residential, the biggest estate agent in Rugeley, thinks the nature of employment is changing permanently and people should stop pining for the past. It’s “bloody great” that a company like Amazon chose to come to “this little old place”, she says fiercely, looking as if she’d like to take the town by the shoulders and give it a shake. “People expect a job for life, but the world isn’t like that any more, is it?” Sarah O’Connor is the FT’s economics correspondent

Google's Sergey Brin: smartphones are 'emasculating' | Technology | guardian.co.uk - 0 views

  • Smartphones are "emasculating" – at least according to Sergey Brin, the co-founder of Google, who explained his view while addressing an audience wearing a computer headset that made him look slightly like a technological pirate.
  • Brin suggested that the way people today use their smartphones was unappealing.
  • "When we started Google 15 years ago," Brin said, "my vision was that information would come to you as you need it. You wouldn't have to search query at all."

  • At the website BoingBoing, the suggestion was that Google Glass would need an appropriately named version of the Android mobile operating system – whose robot-themed icon has pleased many geeks. But each version is named after a dessert (Frozen Yogurt, Jelly Bean) – insufficiently manly, suggested Rob Beschizza.
  • "My vision when we started Google 15 years ago was that eventually you wouldn't have to have a search query at all – the information would just come to you as you needed it," he said. Glass, added Brin, "is the first form factor that can deliver that vision". He said it had improved radically in the past two years since its first versions, which he said were "like a cellphone [mobile phone] strapped to your head".
