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websites are currently built using version 4 of the Hyper Text Markup Language (HTML), that code is gradually being superseded by the newer version 5.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

Me and my data: how much do the internet giants really know? | Technology | The Guardian - 0 views

  • Google is not only the world's largest search engine, it's one of the top three email providers, a social network, and owner of the Blogger platform and the world's largest video site, YouTube. Facebook has the social contacts, messages, wallposts and photos of more than 750 million people.
  • The site also lists my most recent sent and received emails (in both cases a "no subject" conversation thread with a colleague).
  • The big relief comes when I note Google isn't tracking the internet searches I've made on my work account

  • Google isn't totally unhelpfu
  • Every event to which I've ever been invited is neatly listed, alongside its location, time, and whether I said I would attend .
  • One piece of information – a supposed engagement to a schoolfriend, Amy Holmes – stands out. A Facebook "joke" that seemed faintly funny for about a week several years ago was undone by hiding it from any and all Facebook users, friends or otherwise (to avoid an "… is now single!" status update). The forgotten relationship helpfully explains why Facebook has served me up with badly targeted bridalwear adverts for several years, and reassures me that Facebook doesn't know quite everything.
  • This is the core of the main comfort
  • despite their mountain of data, Google and Facebook seem largely clueless, too – they've had no more luck making any sense out of it than I have. And that, for now, is a relief.

BBC - Future - Technology - YouTube: The cult of web video - 0 views

  • With 72 hours of video uploaded to YouTube every minute, almost every moment of modern history is a cult waiting to happen. And it is becoming big business.
  • The billion dollar question is how: how to make your video “go viral”, spreading your particular slice of contemporary culture across the planet like a contagion.
  • Silliness is more important – but not vital, given that both the Kony documentary and the jump from space are entirely serious.
  • ...3 more annotations...
  • Similarly, although sex may remain the most powerful form of advertising, it barely features within this list. Visual excitement won’t do either, given that the year’s second-biggest hit features a single camera pointed at five people and a guitar.
  • irality isn’t actually a property of these videos at all. It’s a property of their audience: a description not of a particular object, but of the ways in which that object is used.
  • To pass on a video or link is to become an evangelist for an instant cult: to gain the status of an initiate, complete with social capital and mutual LOLs. Unlike a biological virus, which hijacks hapless cells no matter what their owners might want, these are infections you must decide to pass on.

Technology News: Internet: Facebook's Relationship With Developers: It's Even More Comp... - 2 views

  • When it comes to developers working with Facebook, "share and share alike" is the new policy.
  • No one rides the Facebook express for free.
  • "If you use any Facebook APIs to build personalized or social experiences, you must also enable people to easily share their experiences back with people on Facebook," Facebook said in a blog post announcing the change.

  • In short, Facebook is moving aggressively to block Twitter and other social media sites from establishing free-rider status on its site

Kill the Internet-and Other Anti-SOPA Myths | The Nation - 0 views

  • in the wake of protests by dozens of websites and large numbers of their users, as well as a virtually unanimous chorus of criticism from leading progressive voices and outlets, including Michael Moore, Cenk Uygur, Keith Olbermann, Alternet, Daily Kos, MoveOn and many people associated with Occupy Wall Street. Judging by the fervor of the anti-SOPA/PIPA protests, a casual observer might think the advocates of the anti-piracy bills were in the same moral league as the torturers at Abu Ghraib.
  • But before we celebrate this “populist” victory, it’s worth remembering that the defeat of SOPA and PIPA was also a victory for the enormously powerful tech industry, which almost always beats the far smaller creative businesses in legislative disputes. (Google alone generated more than $37 billion in 2011, more than double the revenue of all record companies, major and indie combined.)
  • One example of anti-SOPA rhetorical over-reach was a tendency by some to invent sinister motives for the sponsors. On his usually brilliant show The Young Turks, Uygur said that SOPA’s sponsors were “pushing for a monopoly for the MPAA and to kill their competition on the Internet.” This is untrue. They wanted to kill those entities that steal their movies and make money off them, either directly or indirectly. There really is a difference

Examples such as this, or of a theoretical risk of parents being charged for the right to have kids sing “Happy Birthday”, are demagogic. The underlying issue is scale. There is a profound moral difference between loaning a friend a book and posting, without permission, the content of bestsellers for commercial gain—and people and legislators ought to take that distinction into account.

Does Facebook have a problem with women? | Life and style | The Guardian - 0 views

  • Over the past few years, women say they have been banned from the site and seen their pages removed for posting images of cupcakes iced like labia, pictures of breastfeeding mothers and photographs of women post-mastectomy.
  • Yet images currently appearing on the site include a joke about raping a&nbsp;disabled child, a joke about sex with an underage girl and image after image&nbsp;after image of women beaten, bloodied and black-eyed in graphic domestic violence "jokes".
  • There are countless groups with names such as "Sum sluts need their throats slit" and "Its Not 'rape' If They're Dead And If They're Alive Its Surprise Sex".

  • "We take reports of questionable and offensive content very seriously," said the Facebook spokesperson. "However, we also want Facebook to be&nbsp;a place where people can openly discuss issues and express their views, while respecting the rights and feelings of others.
