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websites are currently built using version 4 of the Hyper Text Markup Language (HTML), that code is gradually being superseded by the newer version 5.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.

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.

  • The internet has always revolved around social networking, but the explosion of a fresh generation of communal sites such as MySpace, Bebo and Facebook is taking the phenomenon into new and unchartered territory.
  • One of those applications called iLike - pigging-backing on Facebook's global network - has already attracted more than 6 million members, and is growing by 1 million every few days, making it one of the fastest growing companies of any kind ever

Google and competition: searching for a solution | Tom Watson | Comment is free | guard... - 1 views

  • Some time later this month we are expecting the European commission to decide how it will proceed with its investigation of the search giant Google, following the latter's submission of proposed remedies at the end of January over allegations that it has engaged in a range of anticompetitive practices.
  • Google is a global company and its activities will require a global solution.
  • Google's global revenues were £23.5bn in 2011. Those are its revenues before tax, although Google's approach to tax is another and equally interesting story. Those vast revenues do not come from those who search, but from those who bid to place advertisements alongside the search results. This means that Google has a clear interest to arrange the rankings in a way that maximises its profits and faces a stark conflict of interests when it does so. It has every incentive to demote other companies, who might actually be offering answers or services that are more relevant to the user queries, and to advance its own services.
  • ...3 more annotations...
  • There is no reason why an appropriate remedy that introduces fair rankings should in any way impair the user experience.
  • that Google, with more than 90% of the search market in Europe, is overwhelmingly dominant.
  • Effective remedies will aim to protect competition for the future but need also to acknowledge the past. Google has continued to expand and exploit its position during the period of the investigation and it will be necessary to find a solution that tackles that past misbehaviour and reintroduces something approaching a level playing field.

Forty years of the internet: how the world changed for ever | Technology | The Guardian - 1 views

  • In October 1969, a student typed 'LO' on a computer - and the internet was born
  • Towards the end of the summer of 1969
  • a large grey metal box was delivered to the office of Leonard Kleinrock, a professor at the University of California in Los Angeles.
  • ...32 more annotations...
  • At 10.30pm, as Kleinrock's fellow professors and students crowded around, a computer was connected to the IMP, which made contact with a second IMP, attached to a second computer, several hundred miles away at the Stanford Research Institute, and an undergraduate named Charley Kline tapped out a message.
  • It's impossible to say for certain when the internet began, mainly because nobody can agree on what, precisely, the internet is.
  • It's interesting to compare how much has changed in computing and the internet since 1969 with, say, how much has changed in world politics.
  • On the other hand, the breakthrough accomplished that night in 1969 was a decidedly down-to-earth one
  • Twelve years after Charley Kline's first message on the Arpanet, as it was then known, there were still only 213 computers on the network; but 14 years after that, 16 million people were online, and email was beginning to change the world; the first really usable web browser wasn't launched until 1993, but by 1995 we had Amazon, by 1998 Google, and by 2001, Wikipedia, at which point there were 513 million people online. Today the figure is more like 1.7 billion.
  • on New Year's Day 1994 –&nbsp;only yesterday, in other words –&nbsp;there were an estimated 623 websites.
  • On the one hand, they were there because of the Russian Sputnik satellite launch, in 1957, which panicked the American defence establishment, prompting Eisenhower to channel millions of dollars into scientific research, and establishing Arpa, the Advanced Research Projects Agency, to try to win the arms technology race. The idea was "that we would not get surprised again,"
  • "In a few years, men will be able to communicate more effectively through a machine than face to face," they declared.
  • The few outsiders who knew of the box's existence couldn't even get its name right: it was an IMP, or "interface message processor"
  • It was already possible to link computers by telephone lines, but it was glacially slow, and every computer in the network had to be connected, by a dedicated line, to every other computer, which meant you couldn't connect more than a handful of machines without everything becoming monstrously complex and costly.
  • The solution, called "packet switching" – which owed its existence to the work of a British physicist, Donald Davies – involved breaking data down into blocks that could be routed around any part of the network that happened to be free, before getting reassembled at the other end.
  • Still, Kleinrock recalls a tangible sense of excitement that night as Kline sat down at the SDS Sigma 7 computer, connected to the IMP, and at the same time made telephone contact with his opposite number at Stanford. As his colleagues watched, he typed the letter L, to begin the word LOGIN.
  • One of the most intriguing things about the growth of the internet is this: to a select group of technological thinkers, the surprise wasn't how quickly it spread across the world, remaking business, culture and politics – but that it took so long to get off the ground.
  • In 1945, the American presidential science adviser, Vannevar Bush, was already imagining the "memex", a device in which "an individual stores all his books, records, and communications", which would be linked to each other by "a mesh of associative trails", like weblinks.
  • And in 1946, an astonishingly complete vision of the future appeared in the magazine Astounding Science Fiction. In a story entitled A Logic Named Joe, the author Murray Leinster envisioned a world in which every home was equipped with a tabletop box that he called a "logic":
  • Instead of smothering their research in the utmost secrecy – as you might expect of a cold war project aimed at winning a technological battle against Moscow – they made public every step of their thinking, in documents known as Requests For Comments.
  • Deliberately or not, they helped encourage a vibrant culture of hobbyists on the fringes of academia –&nbsp;students and rank amateurs who built their own electronic bulletin-board systems and eventually FidoNet, a network to connect them to each other.
  • n argument can be made that these unofficial tinkerings did as much to create the public internet as did the Arpanet. Well into the 90s, by the time the Arpanet had been replaced by NSFNet, a larger government-funded network,
  • It was the hobbyists, making unofficial connections into the main system, who first opened the internet up to allcomers.
  • This was the software known as TCP/IP, which made it possible for networks to connect to other networks, creating a "network of networks", capable of expanding virtually infinitely
  • Nevertheless, by July 1992, an Essex-born businessman named Cliff Stanford had opened Demon Internet, Britain's first commercial internet service provider.
  • After a year or so, Demon had between 2,000 and 3,000 users,
  • the @ symbol was introduced in 1971, and the first message, according to the programmer who sent it, Ray Tomlinson, was "something like QWERTYUIOP".
  • A couple of years later I got my first mobile phone, which came with two batteries: a very large one, for normal use, and an extremely large one, for those occasions on which you might actually want a few hours of power
  • For most of us, though, the web is in effect synonymous with the internet, even if we grasp that in technical terms that's inaccurate: the web is simply a system that sits on top of the internet, making it greatly easier to navigate the information there, and to use it as a medium of sharing and communication.
  • The first ever website was his own, at CERN: info.cern.ch.
  • The idea that a network of computers might enable a specific new way of thinking about information, instead of just allowing people to access the data on each other's terminals, had been around for as long as the idea of the network itself: it's there in Vannevar Bush's memex, and Murray Leinster's logics.
  • Web browsers crossed the border into mainstream use far more rapidly than had been the case with the internet itself: Mosaic launched in 1993 and Netscape followed soon after, though it was an embarrassingly long time before Microsoft realised the commercial necessity of getting involved at all. Amazon and eBay were online by 1995. And in 1998 came Google, offering a powerful new way to search the proliferating mass of information on the web.
  • Google, and others, saw that the key to the web's future would be helping users exclude almost everything on any given topic,&nbsp;restricting search results to the most relevant pages.
  • It is absurd – though also unavoidable here – to compact the whole of what happened from then onwards into a few sentences: the dotcom boom, the historically unprecedented dotcom bust, the growing "digital divide", and then the hugely significant flourishing, over the last seven years, of what became known as Web 2.0.
  • The most confounding thing of all is that in a few years' time, all this stupendous change will probably seem like not very much change at all.
  • Will you remember when the web was something you accessed primarily via a computer? Will you remember when there were places you couldn't get a wireless connection? Will you remember when "being on the web" was still a distinct concept, something that described only a part of your life, instead of permeating all of it? Will you remember Google?

Google Glass: is it a threat to our privacy? | Technology | The Guardian - 0 views

  • The next stage is computers that fit on to your body, and Google's idea is that you need only speak to operate it.

  • The first, and most obvious, is the question of privacy. The second is: how will we behave in groups when the distraction of the internet is only an eye movement away?
  • For Google, "privacy" means "what you've agreed to", and that is slightly different from the privacy we've become used to over time. So how comfortable – or uneasy – should we feel about the possibility that what we're doing in a public or semi-public place (or even somewhere private) might get slurped up and assimilated by Google?
  • we already live in a world where the boundaries of what's private and what's public are melting.
  • Google doesn't want to discuss these issues. "We are not making any comment," says a company spokesperson. But other sources suggest that Google's chiefs know that this is a live issue, and they're watching it develop.
  • "People will have to work out what the new normal is,"

Why doesn't everyone 'social media stalk' a potential date? - Telegraph - 0 views

  • ...7 more annotations...
  • Brilliantly the study also broke down what specific things during a good old social media stalk could break a date: an ugly mug shot, lack of humour, aggressive online behaviour, excessive flirting with others online and, my favourite one, oversharing
  • However, this light-hearted poll provides further proof of how we are increasingly judged every single day by our online personas.
  • Of those honest souls, 77 per cent claimed they had turned down a date as a result of something they found out about the said babe or hunk through social media.
  • However, while it’s important for both professional and increasingly personal reasons to be conscientious about what you post online, we do also need to remember that societal attitudes are still playing catch-up with the web.
  • All it takes is for one negative comment, or silly photo to be shared by someone else, and then a digital identity can be marred – giving a falsely negative impression of somebody.
  • The web can be unforgiving and is often out of our control.
  • he internet can do many things – but it simply cannot tell you whether you will get those unexplainable stomach butterflies when you meet your date in person.

  • Image-hosting services
  • social networking services such as MySpace, Orkut, LinkedIn, Facebook and Twitter.

Spotify pushing labels to lower costs, open up free service to phones | The Verge - 0 views

  • Spotify, the popular music subscription service, is due to meet in the coming weeks with its major counterparts in the record industry to renew their licensing agreements. The Verge has learned that managers at Spotify are expected to ask for substantial price breaks from the music labels as well as the rights to extend its free pricing tier to mobile devices.
  • The Stockholm-based Spotify has already started negotiations with Warner Music and will begin talks with Sony and Universal in the coming weeks, according to several music industry sources. (A Spotify spokesperson declined to comment on this story.) These negotiations with music’s "big three" labels will likely go a long way to determining whether Spotify reaches profitability, a crucial threshold as it increasingly competes with Apple and other cash-rich players in the digital music market.
