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websites are currently built using version 4 of the Hyper Text Markup Language (HTML), that code is gradually being superseded by the newer version 5.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

How Much YouTube Do Employees Really Watch at Work? - Alexis C. Madrigal - The Atlantic - 0 views

  • J.C. Penney employees are reported to have watched five million YouTube videos from the office during the month of January.
  • the number of YouTube videos watched on the clock is astronomical, belonging to the category of numbers so large that you should write them like this: 107.&nbsp;
  • YouTube says it streams more than 4 billion videos per day, with about 40 percent coming from the US, so 1.6 billion American streams each day. Let's assume there are 300 million Americans who all watch exactly the same amount of videos each day.

Will Apple's iWatch introduce the age of wearable technology? - Telegraph - 0 views

  • curved touchscreen made from a new type of flexible glass, an array of sensors to monitor exercise patterns and heart rate, “wave and pay” function, access to maps, voice control and wireless integration with the iPhone.
  • That could allow the wearer to take calls and read messages without having to delve into their pocket or bag, or mean the iphone would know when it was in its owner’s hand an unlock automatically.

  • it is beyond the experimentation phase and heading towards production
  • that the age of “wearable technology” is nigh
  • “Apple can launch a new product like no other company because it owns its own retail channel, has privileged real estate in other retailers, and has a brand that’s recognized even by two-year-olds.”
  • There were mobile phones with internet access, mapping software and even touchscreens before the iPhone was introduced in 2007, they just failed to capture mainstream attention.
  • Likewise, wearable technology and smart watches are not Apple ideas. The firm in fact already benefits from third party wearable accessories such as the Nike FuelBand and FitBit, which link to the iPhone and track exercise.
  • All the main technologies – screens, processors, GPS, mobile software, Bluetooth wireless networking – are already mature and in mass use. The problem is cramming them into something small enough to look stylish on a wrist
  • its rival is working on a computer you wear on your face. Google Glass, a project led by Google co-founder Sergey Brin, suggests a near future in which reality is augmented via a pair of spectacles with all the capabilities of a smartphone.
  • Already in public testing, Google Glass’ tiny screen projects the web into your field of vision, while “bone conduction” headphones transmit sound directly through your skull, allowing you to hear your environment at the same time through your ears.

Technology and productivity: The hollow promise of the iEconomy | The Economist - 0 views

  • If fact there is little sign in the data that machines are displacing humans any faster than usual
  • Perhaps because of uncertainty, though that’s a poor explanation for a phenomenon occurring globally.
  • How to put a price on the contribution of Facebook or Twitter to the Arab spring?
  • IN THE battle between David Einhorn and Apple over the latter's $137 billion cash hoard lies a deeper lesson about the outlook for the economy. Mr Einhorn, an activist investor,&nbsp;says Apple clings to its money out of a “Depression mentality”. Perhaps. But the more mundane explanation is that Apple, like many of the world's big companies today, is generating more cash from its existing product line than it can usefully plough back into new projects.
  • Today, we all know Apple’s products, and a lot of us own one. Yet it is hard to identify the impact they or any of today's social-media giants have had on productivity. I was at first delighted with the convenience and freedom to read documents, check Twitter and search the web on the iPad mini I got in December, but it occurred to me recently that this was at best an incremental improvement over doing it on my BlackBerry or laptop. It also provides me with many more ways to waste time. As Tom Toles, the Washington Post’s cartoonist, puts it:
  • No doubt some of those YouTube videos were being watched over Apple products. Not that I blame Apple for Penney’s culture (after all, Google owns YouTube), but it is a reminder that the social-media revolution has been a mixed blessing. Yahoo at one time stood atop the Internet but the ability of its workers to do their job from anywhere may be backfiring on productivity
  • are genuine benefits of social media and the related hardware. In its first few decades the computer/internet revolution re-engineered business processes, enabling companies to interact with each other and customers in more ways at lower cost than ever, producing measurable, bankable results. Now, it’s leading to brand-new consumer products, many of whose &nbsp;benefits are unmeasured or unmeasurable.

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?

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.

  • 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.

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

  • Google Glass is the most hotly anticipated new arrival in "wearable computing" – which experts predict will become pervasive.
  • The next stage is computers that fit on to your body, and Google's idea is that you need only speak to operate it.
  • (To activate Glass you need to tilt your head, or touch the side, and then say, "OK Glass, record a video" or "OK Glass take a picture".)

  • Google has become the company which knows where you are and what you're looking for. Now it's going to be able to compute what it is you're looking at."
  • 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?
  • 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?
  • 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 the entertainment industry's release strategy creates piracy | Technology | guardia... - 0 views

  • If you want people to buy media, you have to offer it for sale. If it's not for sale, they won't buy it, but many of them will still want to watch or hear or play it, and will turn to the darknet to get – for free – the media that no one will sell to them.
  • Today it's hard to find any knowledgeable person who thinks that making more money by delaying a release to an optimal date is possible, except to the extent that the knowledgeable person is selling something.
