Research has found that in some developing nations old mobile phones can help close the digital divide. The Forum for the Future research found that the low cost of these recycled handsets means they can have a very useful second life in poorer nations. But the Forum found that more needed to be done to collect old phones rather than let them rot in landfill sites. |
The report reveals that approximately 15 million mobile phones go out of use every year in the UK. Of the 15 million that are swapped for newer models each year, only 25% get returned to mobile phone firms for recycling or re-use. The slowly growing mass of unrecycled, discarded phones has now reached 90 million handsets, the equivalent of 9,000 tonnes of waste, estimates James Goodman, report author and a senior adviser at the Forum for the Future. "It's quite common for people to have two or three phones just lying around," said Mr Goodman. |
Many of these older phones could end up in landfill sites leaking the potentially toxic materials they are made of into the wider world, said Mr Goodman. Far better, he said, to hand the phone back to an operator who can send it overseas where it can enjoy a second lease of life. "We've heard the environmental argument for handing a phone back," said Mr Goodman, "but there's a strong social argument too." Older mobile phones are proving particularly useful in poorer nations where people want to use a mobile and keep in touch with friends and family but do not have the income to buy the most up to date model. The Forum for the Future report took an in-depth look at Romania where reconditioned mobile phones were proving very popular. "It's an interesting country because it has a really crap fixed line network," said Mr Goodman, "and there's a real desire for people to get mobile phones." But the relatively low wages in Romania, which is one of the poorest countries in Europe, mean few people can afford a shiny new phone. "The affordability of the handsets is a real barrier to getting one," he said. Reconditioned handsets have boosted take-up of mobiles as the report revealed that almost one-third of Romanian pre-pay mobile phone users were using reconditioned handsets. The re-used handsets tend to be about one-third of the price of a new handset. Georgeta Minciu, a Romanian part-time cleaner, said: "Normally a mobile phone would not be possible on my wages. I am a single parent - keeping in touch with my daughter is important to me." "This is the only way I can afford to have a phone," she said. Mr Goodman said phone operators and consumers needed to do more to ensure that more of Britain's mobile mountain made it overseas. But, he added, those keen to use a mobile will not accept any old handset. "If its more than a few years old people are not going to want it," he said. |
PlayStation 3 chip to be unveiled |
Details of the chip designed to power Sony's PlayStation 3 console will be released in San Francisco on Monday. |
Sony, IBM and Toshiba, who have been working on the Cell processor for three years, will unveil the chip at a technology conference. The chip is reported to be up to 10 times faster than current processors. It is being designed for use in graphics workstations, the new PlayStation console, and has been described as a supercomputer on a chip. Sony has said the Cell processor could be used to bridge the gap between movies and video games. Special effects and graphics designed for films could be ported for use directly in a video game, Sony told an audience at the E3 exhibition in Los Angeles last year. |
Cell could also be marketed as an ideal technology for televisions and supercomputers, and everything in between, said Kevin Krewell, the editor in chief of Microprocessor Report. The chip will be made of several different processing cores that work on tasks together. The PlayStation 3 is expected in 2006 but developers are expecting to get prototypes early next year to tune games that will appear on it at launch. Details of the chip will be released at the International Solid State Circuits Conference in San Francisco. Some details have already emerged, however. When put inside powerful computer servers, the Cell consortium expects it to be capable of handling 16 trillion floating point operations, or calculations, every second. |
The chip has also been refined to be able to handle the detailed graphics common in games and the data demands of films and broadband media. IBM said it would start producing the chip in early 2005 at manufacturing plants in the US. The first machines off the line using the Cell processor will be computer workstations and servers. A working version of the PS3 is due to be shown off in May 2005 but a full launch of the next generation console is not expected to start until 2006. "In the future, all forms of digital content will be converged and fused onto the broadband network," said Ken Kutaragi, chief operating officer of Sony, said last year. "Current PC architecture is nearing its limits," he added. |
Intel unveils laser breakthrough |
Intel has unveiled research that could mean data is soon being moved around chips at the speed of light. |
Scientists at Intel have overcome a fundamental problem that before now has prevented silicon being used to generate and amplify laser light. The breakthrough should make it easier to interconnect data networks with the chips that process the information. The Intel researchers said products exploiting the breakthrough should appear by the end of the decade. |
"We've overcome a fundamental limit," said Dr Mario Paniccia, director of Intel's photonics technology lab. Writing in the journal Nature, Dr Paniccia - and colleagues Haisheng Rong, Richard Jones, Ansheng Liu, Oded Cohen, Dani Hak and Alexander Fang - show how they have made a continuous laser from the same material used to make computer processors. Currently, says Dr Paniccia, telecommunications equipment that amplifies the laser light that travels down fibre optic cables is very expensive because of the exotic materials, such as gallium arsenide, used to make it. |
Telecommunications firms and chip makers would prefer to use silicon for these light-moving elements because it is cheap and many of the problems of using it in high-volume manufacturing have been solved. "We're trying to take our silicon competency in manufacturing and apply it to new areas," said Dr Paniccia. While work has been done to make some of the components that can move light around, before now silicon has not successfully been used to generate or amplify the laser light pulses used to send data over long distances. This is despite the fact that silicon is a much better amplifier of light pulses than the form of the material used in fibre optic cables. This improved amplification is due to the crystalline structure of the silicon used to make computer chips. Dr Paniccia said that the structure of silicon meant that when laser light passed through it, some colliding photons rip electrons off the atoms within the material. "It creates a cloud of electrons sitting in the silicon and that absorbs all the light," he said. But the Intel researchers have found a way to suck away these errant electrons and turn silicon into a material that can both generate and amplify laser light. Even better, the laser light produced in this way can, with the help of easy-to-make filters, be tuned across a very wide range of frequencies. Semi-conductor lasers made before now have only produced light in a narrow frequency ranges. The result could be the close integration of the fibre optic cables that carry data as light with the computer chips that process it. Dr Paniccia said the work was the one of several steps needed if silicon was to be used to make components that could carry and process light in the form of data pulses. "It's a technical validation that it can work," he said. |
China net cafe culture crackdown |
Chinese authorities closed 12,575 net cafes in the closing months of 2004, the country's government said. |
According to the official news agency most of the net cafes were closed down because they were operating illegally. Chinese net cafes operate under a set of strict guidelines and many of those most recently closed broke rules that limit how close they can be to schools. The move is the latest in a series of steps the Chinese government has taken to crack down on what it considers to be immoral net use. |
The official Xinhua News Agency said the crackdown was carried out to create a "safer environment for young people in China". Rules introduced in 2002 demand that net cafes be at least 200 metres away from middle and elementary schools. The hours that children can use net cafes are also tightly regulated. China has long been worried that net cafes are an unhealthy influence on young people. The 12,575 cafes were shut in the three months from October to December. China also tries to dictate the types of computer games people can play to limit the amount of violence people are exposed to. |
Net cafes are hugely popular in China because the relatively high cost of computer hardware means that few people have PCs in their homes. This is not the first time that the Chinese government has moved against net cafes that are not operating within its strict guidelines. All the 100,000 or so net cafes in the country are required to use software that controls what websites users can see. Logs of sites people visit are also kept. Laws on net cafe opening hours and who can use them were introduced in 2002 following a fire at one cafe that killed 25 people. During the crackdown following the blaze authorities moved to clean up net cafes and demanded that all of them get permits to operate. In August 2004 Chinese authorities shut down 700 websites and arrested 224 people in a crackdown on net porn. At the same time it introduced new controls to block overseas sex sites. The Reporters Without Borders group said in a report that Chinese government technologies for e-mail interception and net censorship are among the most highly developed in the world. |
Security scares spark browser fix |
Microsoft is working on a new version of its Internet Explorer web browser. |
The revamp has been prompted by Microsoft's growing concern with security as well as increased competition from rival browsers. Microsoft said the new version will be far less vulnerable to the bugs that make its current browser a favourite of tech-savvy criminals. Test versions of the new program, called IE 7, are due to be released by the summer. |
The announcement about Internet Explorer was made by Bill Gates, Microsoft chairman and chief software architect, during a keynote speech at the RSA Security conference currently being held in San Francisco. Although details were scant, Mr Gates, said IE7 would include new protections against viruses, spyware and phishing scams. This last category of threats involves criminals setting up spoof websites that look identical to those of banks and try to trick people into handing over login and account information. |
In a bid to shore up the poor security in IE 6, Microsoft has regularly issued updates to patch loopholes exploited by criminals and the makers of nuisance programs such as spyware. Earlier this month it released a security bulletin that patched eight critical security holes - some of which were found in the IE browser. Microsoft has also made a series of acquisitions of small firms that specialise in computer security. One of the first fruits of these acquisitions appeared last month with the release of a Microsoft anti-spyware program. An own-brand anti-virus program is due to follow by the end of 2005. The decision to make Internet Explorer 7 is widely seen as a U-turn because, before now, Microsoft said it had no need to update the browser. Typically new versions of its browser appear with successive versions of the Windows operating system. A new version of IE was widely expected to debut with the next version of Windows, codenamed Longhorn, which is due to appear in 2006. The current version of Internet Explorer is four years old, and is widely seen as falling behind rivals such as Firefox and Opera. There are also persistent rumours that search engine Google is poised to produce its own brand browser based on Firefox. In particular the Firefox browser has been winning fans and users since its first full version was released in November 2004. Estimates of how many users Firefox has won over vary widely. According to market statistics gathered by Websidestory, Firefox's market share is now about 5% of all users. However, other browser stat gatherers say the figure is closer to 15%. Some technical websites report that a majority of their visitors use the Firefox browser. Internet Explorer still dominates with a share of about 90% but this is down from a peak of almost 96% in mid-2004. |
Google and Apple release contact tracing app API |
Google and Apple delivered their contact tracing app API to public health agencies across the globe. The apps would allow Bluetooth pings between smartphones within six and a half feet of each other. And in theory, these apps would notify you if you had been in close contact with someone diagnosed with COVID-19. In practice, public health authorities will have to encourage around 60% people in a given state or country to download the app in order to meaningfully conduct contact tracing/exposure notification. |
Computerworld executive editor Ken Mingis and PCWorld/Macworld’s Michael Simon join Juliet to discuss Apple and Google’s unprecedented collaboration, privacy concerns and how state and federal governments will utilize the API. |
Sun offers processing by the hour |
Sun Microsystems has launched a pay-as-you-go service which will allow customers requiring huge computing power to rent it by the hour. |
Sun Grid costs users $1 (53p) for an hour's worth of processing and storage power on systems maintained by Sun. So-called grid computing is the latest buzz phrase in a company which believes that computing capacity is as important a commodity as hardware and software. Sun likened grid computing to the development of electricity. |
The system could mature in the same way utilities such as electricity and water have developed, said Sun's chief operating officer Jonathan Schwartz. "Why build your own grid when you can use ours for a buck an hour?" he asked in a webcast launching Sun's quarterly Network Computing event in California. The company will have to persuade data centre managers to adopt a new model but it said it already had interest from customers in the oil, gas and financial services industries. |
Some of them want to book computing capacity of more than 5,000 processors each, Sun said. Mr Schwartz ran a demonstration of the service, showing how data could be processed in a protein folding experiment. Hundreds of servers were used simultaneously, working on the problem for a few seconds each. |
Although it only took a few seconds, the experiment cost $12 (£6.30) because it had used up 12 hour's worth of computing power. The Sun Grid relies on Solaris, the operating system owned by Sun. Initially it will house the grid in existing premises and will use idle servers to test software before shipping it to customers. It has not said how much the system will cost to develop but it already has a rival in IBM, which argues that its capacity on-demand service is cheaper than that offered by Sun. |
Lasers help bridge network gaps |
An Indian telecommunications firm has turned to lasers to help it overcome the problems of setting up voice and data networks in the country. |
Tata Teleservices is using the lasers to make the link between customers' offices and its own core network. The laser bridges work across distances up to 4km and can be set up much faster than cable connections. In 12 months the lasers have helped the firm set up networks in more than 700 locations. |
"In this particular geography getting permission to dig the ground and lay the pipes is a bit of a task," said Mr R. Sridharan, vice president of networks at Tata. "Heavy traffic and the layout under the ground mean that digging is uniquely difficult," he said. In some locations, he said, permission to dig up roads and lay cables was impossible to get. He said it was far easier to secure permission for putting networking hardware on roofs. This has led Chennai-based Tata to turn to equipment that uses lasers to make the final mile leap between Tata's core network and the premises of customers. The Lightpointe laser bridges work over distances of up to 4km and are being used to route both voice and data from businesses on to the backbone of the network. The hardware works in pairs and beam data through the air in the form of laser pulses. |
The laser bridges can route data at speeds up to 1.25gbps (2,000 times faster than a 512kbps broadband connection) but Tata is running its hardware at more modest speeds of 1-2mbps. The lasers are also ideal for India because of its climate. "It's particularly suitable as the rain rate is a little low and it's hardly ever foggy," he said. In places where rain is heavy and fog is common laser links can struggle to maintain good connection speeds. The laser links also take far less time to set up and get working, said Mr Sridharan. "Once we get the other permissions, normal time period for set up is a few hours," he said. By contrast, he said, digging up roads and laying cables can take weeks or months. This speed of set up has helped Tata with its aggressive expansion plans. Just over 12 months ago the firm had customers in only about 70 towns and cities. But by the end of March the firm hopes to reach more than 1,000. "Speed is very important because of the pace of competition," said Mr Sridharan. |
Game firm holds 'cast' auditions |
Video game firm Bioware is to hold open auditions for people to become cast members for future games. |
The company, which makes role playing games such as Knights of the Old Republic and Neverwinter Nights, is seeking people aged 18 to 99. The Canada-based company says it was looking for "a wide variety of people to use as face models for characters". Everyone chosen to appear in a video game will receive a performer's fee for the use of their image. The company is inviting people to come along to a shopping mall in West Edmonton, Alberta, on Friday and Saturday, bringing along a piece of photo identification. |
"There are hundreds and hundreds of characters in a typical Bioware game," said Shauna Perry, Bioware's audio and external resources producer. "Those people live in any city and village and so we need ordinary people, people with interesting faces." She added: "Not everyone is a model in the world so we don't want just models in our games." People chosen to appear in a game will have their head scanned in three dimensions. Hundreds of photos of the person's head are taken so that a model of the head can be generated in 3D. "The 3D model will look exactly like the person - it's really quite incredible how detailed they are," said Ms Perry. She said chosen participants will have no control over how the image is used in a computer game. "We cannot give people any control over how the images are used. "But their face could be used in multiple games - so they could be the hero in one, the villain in another and just a merchant in a third." |
Sony PSP console hits US in March |
US gamers will be able to buy Sony's PlayStation Portable from 24 March, but there is no news of a Europe debut. |
The handheld console will go on sale for $250 (£132) and the first million sold will come with Spider-Man 2 on UMD, the disc format for the machine. Sony has billed the machine as the Walkman of the 21st Century and has sold more than 800,000 units in Japan. The console (12cm by 7.4cm) will play games, movies and music and also offers support for wireless gaming. Sony is entering a market which has been dominated by Nintendo for many years. |
It launched its DS handheld in Japan and the US last year and has sold 2.8 million units. Sony has said it wanted to launch the PSP in Europe at roughly the same time as the US, but gamers will now fear that the launch has been put back. Nintendo has said it will release the DS in Europe from 11 March. "It has gaming at its core, but it's not a gaming device. It's an entertainment device," said Kaz Hirai, president of Sony Computer Entertainment America. |
Warnings about junk mail deluge |
The amount of spam circulating online could be about to undergo a massive increase, say experts. |
Anti-spam group Spamhaus is warning about a novel virus which hides the origins of junk mail. The program makes spam look like it is being sent by legitimate mail servers making it hard to spot and filter out. Spamhaus said that if the problem went unchecked real e-mail messages could get drowned by the sheer amount of junk being sent. |
Before now many spammers have recruited home PCs to act as anonymous e-mail relays in an attempt to hide the origins of their junk mail. The PCs are recruited using viruses and worms that compromise machines via known vulnerabilities or by tricking people into opening an attachment infected with the malicious program. Once compromised the machines start to pump out junk mail on behalf of spammers. Spamhaus helps to block junk messages from these machines by collecting and circulating blacklists of net addresses known to harbour infected machines. But the novel worm spotted recently by Spamhaus routes junk via the mail servers of the net service firm that infected machines used to get online in the first place. In this way the junk mail gets a net address that looks legitimate. As blocking all mail from net firms just to catch the spam is impractical, Spamhaus is worried that the technique will give junk mailers the ability to spam with little fear of being spotted and stopped. Steve Linford, director of Spamhaus, predicted that if a lot of spammers exploit this technique it could trigger the failure of the net's e-mail sending infrastructure. David Stanley, UK managing director of filtering firm Ciphertrust, said the new technique was the next logical step for spammers. "They are adding to their armoury," he said. The amount of spam in circulation was still growing, said Mr Stanley, but he did not think that the appearance of this trick would mean e-mail meltdown. But Kevin Hogan, senior manager at Symantec security response, said such warnings were premature. "If something like this mean the end of e-mail then e-mail would have stopped two-three years ago," said Mr Hogan. While the technique of routing mail via mail servers of net service firms might cause problems for those that use blacklists and block lists it did not mean that other techniques for stopping spam lost their efficacy too. Mr Hogan said 90% of the junk mail filtered by Symantec subsidiary Brightmail was spotted using techniques that did not rely on looking at net addresses. For instance, said Mr Hogan, filtering out e-mail messages that contain a web link can stop about 75% of spam. |
Warning over tsunami aid website |
Net users are being told to avoid a scam website that claims to collect cash on behalf of tsunami victims. |
The site looks plausible because it uses an old version of the official Disasters Emergency Committee webpage. However, DEC has no connection with the fake site and says it has contacted the police about it. The site is just the latest in a long list of scams that try to cash in on the goodwill generated by the tsunami disaster. |
The link to the website is contained in a spam e-mail that is currently circulating. The message's subject line reads "Urgent Tsunami Earthquake Appeal" and its text bears all the poor grammar and bad spelling that characterises many other phishing attempts. The web address of the fake site is decuk.org which could be close enough to the official www.dec.org.uk address to confuse some people keen to donate. Patricia Sanders, spokeswoman for the Disaster Emergency Committee said it was aware of the site and had contacted the Computer Crime Unit at Scotland Yard to help get it shut down. She said the spam e-mails directing people to the site started circulating two days ago shortly after the domain name of the site was registered. It is thought that the fake site is being run from Romania. Ms Sanders said DEC had contacted US net registrars who handle domain ownership and the net hosting firm that is keeping the site on the web. |
DEC was going to push for all cash donated via the site to be handed over to the official organisation. BT and DEC's hosting company were also making efforts to get the site shut down, she said. |
Ms Sanders said sending out spam e-mail to solicit donations was not DEC's style and that it would never canvass support in this way. She said that DEC hoped to get the fake site shut down as soon as possible. All attempts by the BBC News website to contact the people behind the site have failed. None of the e-mail addresses supplied on the site work and the real owner of the domain is obscured in publicly available net records. This is not the first attempt to cash in on the outpouring of goodwill that has accompanied appeals for tsunami aid. One e-mail sent out in early January came from someone who claimed that he had lost his parents in the disaster and was asking for help moving an inheritance from a bank account in the Netherlands. The con was very similar to the familiar Nigerian forward fee fraud e-mails that milk money out of people by promising them a cut of a much larger cash pile. Other scam e-mails included a link to a website that supposedly let people donate money but instead loaded spyware on their computers that grabbed confidential information. In a monthly report anti-virus firm Sophos said that two e-mail messages about the tsunami made it to the top 10 hoax list during January. Another tsunami-related e-mail is also circulating that carries the Zar worm which tries to spread via the familiar route of Microsoft's Outlook e-mail program. Anyone opening the attachment of the mail will have their contact list plundered by the worm keen to find new addresses to send itself to. |
