Sleep Waking is an art project that uses EEG and EKG to record brainwaves and heart activity of a sleeping person and feeds them into a humanoid robot (a Kondo KHR-2HV). The robot turns the data into an interpretive dance. In short, the robot dances your dreams. In addition, rapid eye movement is used to control the head of the robot, so if the sleeper’s eye looks left – the robots head looks left.

Live Science reports on the project:

The use of the EEG data is a bit more complex [than the use of rapid eye movements]. Running it through a machine learning algorithm, we identified several patterns from a sample of the data set (both REM and non-REM events). We then associated preprogrammed robot behaviors to these patterns. Using the patterns like filters, we process the entire data set, letting the robot act out each behavior as each pattern surfaces in the signal. Periods of high activity (REM) where [sic] associated with dynamic behaviors (flying, scared, etc.) and low activity with more subtle ones (gesturing, looking around, etc.). The “behaviors” the robot demonstrates are some of the actions I might do (along with everyone else) in a dream.” [LiveScience]

And here’s a video of it, dancing away [Alt].
The project is the brainchild of Fernando Orellana and Brendan Burns, who used the equipment of The Albany Regional Sleep Disorder Center in New York to record the data.

A robot dancing your dreams. Can’t help but feel inspired by that quip.

It seems that the telcos and the cable companies just can’t stop making questionable claims against each other. It’s been going on for years, but it seems that the telcos are finally going to court over it. Last month, we mentioned that Verizon was suing Time Warner Cable over what it claimed was false advertising, but then had to embarrassingly admit that its own ads were misleading as well. Now, AT&T is suing Comcast for misleading advertising thanks to a print ad campaign that suggests AT&T DSL customers will have to put a huge cabinet on the side of their homes. As AT&T points out, it only needs to install such cabinets for one out of approximately 750 homes — and it never installs them on private property without the permission of the homeowner. To be honest, it hardly seems like that big of a deal either. If it took a big box on the side of my house to get great internet speeds, I’d be fine with it.

But the thing that seems most strange, is this constant focus on attacking each other with exaggerated and misleading claims. That’s a sign of a stagnating industry. A growing industry focuses on promoting what’s new and what great features it has. Or, if it does mention the competition at all, it’s to show why its service is better — not why the other’s is worse. The fact that the two sides are attacking each other in this manner, while broadband providers in other countries are spending their money on actual improvements is rather disappointing. If these broadband providers put half as much effort into just offering better service, perhaps it wouldn’t have to resort to name calling and lawsuits against each other.

Spam – the scourge of every e-mail inbox – celebrates its 30th anniversary this weekend.

The first recognisable e-mail marketing message was sent on 3 May, 1978 to 400 people on behalf of DEC – a now-defunct computer-maker.

The message was sent via Arpanet – the internet’s forerunner – and won its sender much criticism from recipients.

Thirty years on, spam has grown into an underground industry that sends out billions of messages every day.

Statistics gathered by the FBI suggest that 75% of net scams snare people through junk e-mail. In 2007 these cons netted criminals more than $239m (£121m).

Statistics suggest that more than 80%-85% of all e-mail is spam or junk and more than 100 billion spam messages are sent every day.

The majority of these messages are being sent via hijacked home computers that have been compromised by a computer virus.

Quick complaint

The sender of the first junk e-mail message was Gary Thuerk and it was sent to advertise new additions to DEC’s family of System-20 minicomputers.

It invited the recipients, all of whom were on Arpanet and lived on the west coast of the US, to go to one of two presentations showing off the capabilities of the System-20.

Reaction to the message was swift, with complaints reportedly coming from the US Defense Communications Agency, which oversaw Arpanet, and took Mr Thuerk’s boss to task about it.

Despite Mr Thuerk’s pioneering spam it took many years for unsolicited commercial e-mail to become a nuisance.

It took until 1993 before it won the name of spam – a name bestowed on it by Joel Furr – an administrator on the Usenet chat system.

Mr Furr reputedly got his inspiration for the name from a Monty Python sketch set in a restaurant whose menu heavily featured the processed meat.

The sketch ended with everyone in the restaurant, encouraged by a troupe of chanting Vikings, shouting: “Spam. Spam. Spam. Spam. Spam.”

April 1994 saw another pioneering moment in the history of spam when immigration lawyers Canter and Siegel sent a commercial spam message to more than 6,000 Usenet discussion groups.

The Canter and Siegel e-mail is widely seen as the moment when the commercialisation of the net began and opened the floodgates that led to the deluge of spam seen today.

Since those days spam has grown to be a nuisance and is now used by many hi-tech crime gangs as the vehicle for a variety of scams and cons.

“Spam is a burden on all of us,” said Graham Cluley, senior technology consultant at Sophos. “What’s worse is that a lot of spam is deliberately malicious today, aiming to steal your bank account information or install malware.”<P

“Mom, where are you calling from Your voice is trembling, are you sure everything is alright”

These were the first words Carmen Hernandez heard after getting through to her son on the phone following the massive earthquake that struck Peru in August 2007.

Mrs Hernandez lived in Pisco, where the quake hit hardest.

“Please keep talking, it’s so good to hear your voice,” she replied.

The huge quake left at least 500 people dead and thousands homeless in the Ica region, south of the capital Lima.

It instantly wiped out electricity, fresh water and communication infrastructures.

But Mrs Hernandez was able to speak to her son in Spain thanks to the work of charity Telecoms Sans Frontieres.

Tough call

The group are currently on standby to deploy to Burma; they are waiting for authorisation to enter the country.

“The UN-sponsored organisation specialises in setting up communication links at times of emergency, for use by charities and those affected.

“In natural disasters in particular, the communications are disrupted,” explained Oisin Walton of TSF, during a training exercise in Pau, southwest France.

“The GSM antennas are down, the landlines are down.”

TSF was started to address this need and to take the burden of setting up temporary communications infrastructures away from other charities with more pressing concerns.

But the organisation, which is 10 years old this year, was started by two charity workers because of a much simpler need.

“We saw that people would come to us and they would pull a little piece of paper from their shoe with a telephone number on it,” explained co-founder Monique Lanne-Petit.

“[They would] ask us, ‘would you please call this person who is my friend, or my relative and tell them that I am here and tell them that I am safe’”

The first phone call they offered anyone was to an Albanian refugee caught up during the conflict in Kosovo in 1998.

“He was in tears and smiling at the same time,” said Miss Lanne-Petit. “It clearly made a tremendous impact on his life.”

Since then, TSF has deployed on countless missions all over the world, offering calls to thousands of people.

The group worked in Sri Lanka and Indonesia following the tsunami in 2004; in Pakistan following the earthquake in 2005 and in Peru in 2007.

Recent funding of $2m from the UN Foundation and the Vodafone Group Foundation means that the charity – which still only has 15 permanent staff – can be “in country” for 200 days every year.

No number

During those operations the charity offers two basic services: a communications infrastructure for charities and what it calls “humanitarian calling operations”.

TSF KITLIST

• BGan satellite link (data and voice: 496kbps). Primary connection
• Gan M4 satellite link (data and voice: 64kbps). Used as backup
• Large VSAT satellite dish for long term deployments
• At least two satellite phones including a mobile device
• Mobile phones and local sim cards if GSM infrastructure intact
• Routers and access points for communication centre
• Wireless relays to extend coverage
• PCs, printer and scanner
• GPS
• Power packs including car batteries and solar panels

“We go around either the camps or the affected villages where we offer to each affected family in the area a three-minute call anywhere in the world,” explained Mr Walton.

This was the service that Mrs Hernandez had used in Peru. During that operation, she was one of more than 600 families who made a call to a loved one.

“Generally people call their family either in the country or abroad,” explained Jean-Francois Cazenove, the other co-founder of TSF.

“Many people call abroad because a lot of money comes from the diasporas in these countries.”

Others just want to tell relatives they are alive or update them on the situation. But, according to Mr Cazenove, in certain disasters the calls also have another more crucial function.

“When people are in refugee camps, they are just a number, but when they call their family, their father, their mother, they are a person again,” he said.

Precious resource

Clearly, the phone calls are important to people. But at times of disaster, the distribution of food, medical supplies and shelter are a priority.

And TSF play a part with this as well.

“With so many actors in the field – local, international NGOs, UN agencies, local authorities – coordination is very important,” said Mr Walton.

The charity sets up emergency telecommunications centres to allow groups to talk effectively.

These contain all the telecoms and IT equipment found in a normal office – including printers, scanners, laptops and phones – housed in a tent or temporary shelter.

Connections are via satellite links which offer anything between 64 kilobytes and half a megabyte of bandwidth. This can cost up to $10,000 per day.

So to reduce the amount of content downloaded, TSF has developed its own kit, including a router which automatically configures laptops that connect to the network.

The router automatically stops bandwidth heavy applications such as Skype and peer-to-peer programs.

In addition, it blocks web content which sucks up precious bandwidth.

“When users download a web page it blocks the photographs,” explained Mr Walton.

“A photograph maybe just 30kb but if there are 10 photographs that’s 300kb.”

Red alert

Key to all of TSF’s activities is speed.

During the recent training session, volunteers constructed a fully functioning communications centre and were browsing the web within one hour.

The setup included two satellite connections and even wireless relays to increase the coverage of the connection.

Most of the kit – weighing 200kg – had been carried in three suitcases that are packed and ready to go at all times.

“We generally deploy within three hours,” explained Mr Cazenove. “We have a commitment with the UN to deploy within 48 hours but we are generally in the field within 24.”

Alerts generally come via text message from a web service called the Global Disaster Alert and Coordination System (GDacs).

During the training, the team received a red alert warning them of a possible tsunami triggered by an earthquake in the Pacific.

Within minutes, they were on the phone to their base in Thailand, to check that they were ready to go. TSF also has a base in Nicaragua.

The alert was eventually downgraded – it had occurred in a largely unpopulated area – but the team had been ready to drop everything and board a flight.

“It is very important for us to deploy rapidly because rapid response is the key to saving lives,” said Mr Cazenove.

The liberalisation of the UK postal service has produced “no significant benefits” for both households and small businesses, a report has said.

That is the initial finding of an independent review of the UK postal sector commissioned by the government.

It warned there was now a threat to the Royal Mail’s financial stability.

The Royal Mail’s 350-year monopoly ended at the start of 2006, when other licensed operators were given the right to collect and deliver mail.

‘Untenable’

The independent panel warned that the “substantial threat” to the Royal Mail’s financial security threatened the universal service – the collection and delivery to all UK addresses.

As a result, the independent panel – which will produce its full report in the summer – said the continuing “status quo is not tenable”.

“The policies needed to establish a sustainable future will be the focus of our report later this year,” they said.

While the initial report said homes and small firms had not gained from the increased competition, it said large companies had “seen clear benefits from liberalisation – choice, lower prices and more assurance about the quality of the mail service”.

It says these large firms have benefited from the big growth in competition in the bulk mail sector – postal firms that collect, sort and transport bulk mail before handing it over to the Royal Mail for the final delivery.

Yet at the same time, the report found that the Royal Mail still had “virtually no competition” in the delivery of addressed letters over the “final mile” to letterboxes.<P

The UN is to again suspend distribution of food aid to Palestinians in the Gaza Strip because of fuel shortages, the UN Relief Works Agency (UNRWA) has said.

The announcement was made several hours after Israel closed two major crossing points into the territory after they came under mortar fire.

UNRWA stopped distributing food aid in Gaza two weeks ago for several days after its vehicles ran out of fuel.

Israel has blockaded Gaza since Hamas took power in the territory last year.

More than 80% of Gaza’s population relies on humanitarian assistance, with UN food aid going to about 1.1 million people. A high proportion of them are children.

Aid to 650,000 people would be halted, UNRWA spokesman Chris Gunness said.

The suspension would begin late on Monday, he said, when fuel supplies were expected to be completely exhausted.

He said both the Palestinians and Israelis had promised that UNRWA would receive the fuel it needs to maintain its deliveries, but none had arrived.

Rice visit

The UN was also forced to halt aid deliveries last month when fuel ran out.

Chronic fuel shortages in the Gaza Strip were hampered by a strike by Gaza’s fuel distributors and petrol station owners.

But Israel also tightened fuel deliveries to the Nahal Oz terminal on the border after Palestinian militants killed two Israelis.

The Nahal Oz terminal and the Karni crossings – through which most food, fuel and humanitarian aid reaches Gaza – were closed by Israel on Sunday after a mortar attack, AFP news agency said.

Israel has said the crossings are being deliberately targeted by Hamas.

Israeli Prime Minister Ehud Olmert and Palestinian Authority President Mahmoud Abbas are to meet on Monday after meetings with US Secretary of State Condoleezza Rice.

She is in the Middle East to lay the ground for a trip by US President George W Bush to the region later this month.

The current peace process, launched at a Middle East conference hosted by Mr Bush in November, has been dogged by a lack of progress.

Ms Rice said she still believed a peace agreement between the Israelis and Palestinians was possible by the year’s end, according to commitments made by both sides last year

Details of rules controlling the number of skilled migrants from outside the European Economic Area working in the UK are due to be revealed later.

Ministers say the rules would have cut skilled migrants last year from outside the EEA (the EU plus Norway, Iceland and Liechtenstein) by 12%.

From the autumn such migrants will need to accrue the required number of points to enter Britain.

Points will be awarded according to qualifications and salary prospects.

Non-EEA applicants for jobs in the UK will have to have the correct number of points as well as a job offer from an employer.

Employers will also be required to show they cannot recruit skilled resident workers.

Entertainers

The Home Office says that in the 12 months to last September, 65,000 skilled workers from outside the EEA were allowed in, but that under the new rulesthere would have been almost 8,000 fewer.

Details will also be revealed later about how many points entertainers and sportsmen and women will need to come to the UK on short-term contracts.

The Home Office has said such workers attending one-off events, such as the Edinburgh International Festival, will not require points, but will need a visitors’ visa.

The new immigration points system, which is based on education, previous salary and age, was announced two years ago.

The Home Office says the aim of the system, being phased in this year, is to ensure that only those with the skills most in need gain entry to the UK.

Staged introduction

The more skills a worker has, and the more those skills are in demand, the more points they will gain, increasing the likelihood of entry.

The first stage of the new points-based system, which applies to highly-skilled workers already in the country who want to extend their stay, came into force in February.

The second set of requirements, details of which will be announced today, will focus on skilled workers and filling gaps in the labour market. An independent committee will advise ministers on which skills the economy needs.

Other stages covering temporary workers, young people and students will be introduced later.

Adobe has announced a plan to try to get its Flash player installed on more mobile devices and set-top boxes.

Dubbed Open Screen the initiative lifts restrictions on how its multimedia handling software can be used.

Adobe will stop charging licencing fees for mobile versions of Flash and plans to publish information about the inner workings of the code.

In taking this step Adobe hopes to repeat on mobiles the success its Flash technology has enjoyed on the web.

Video deal

Adobe estimates that its Flash player is installed on more than 98% of net-connected desktop computers.

The Open Screen plan will build on Flash Lite – Adobe’s version of its multimedia player designed for mobile gadgets – that is already on millions of handhelds.

The ultimate aim of Open Screen is to make it much easier for TV and film makers to send their content to mobiles and on other devices such as set-top boxes.

It aims to do this by creating one flexible player technology that can run on any small-form device but only demands that developers write code once for it.

At the moment trying to get games or video on to different devices can be frustrating because of the plethora of hardware and software quirks on each gadget.

Adobe’s four-step plan involves ending license fees; removing restrictions on the use of files in SWF and FLV format; publishing detailed information about the program interfaces for its Flash player and opening up information about its Flash streaming technology.

The move is the latest in a series that are aiming to open up Flash and get more devleopers working with it.

It is also part of the larger plan for Adobe Air – an overarching code development system that aims to bridge the gap between web and desktop applications.

Adobe said it was working with Arm, SonyEricsson, Nokia, LG and other gadget makers on the Open Screen initiative as well as content partners such as the BBC, MTV and NBC.

Adobe faces competition from Microsoft which is trying to get Silverlight – its answer to Air – on to mobiles too. <p

Many tropical insects face extinction by the end of this century unless they adapt to the rising global temperatures predicted, US scientists have said.

Researchers led by the University of Washington said insects in the tropics were much more sensitive to temperature changes than those elsewhere.

In contrast, higher latitudes could experience an insect population boom.

The scientists said changes in insect numbers could have secondary effects on plant pollination and food supplies.

In the research published in Proceedings of the National Academy of Sciences, the US scientists studied how temperature changes between 1950 and 2000 had affected 38 species of insects.

“In the tropics, many species appear to be living at or near their thermal optimum, a temperature that lets them thrive”

Unlike warm-blooded animals, cold-blooded organisms cannot regulate their body temperatures by growing a coat of fur or shedding it when it gets warm. They are instead limited to either seek shade when hot or sun themselves when cool.

The scientists predicted such species would struggle to cope with the 5.4C rise in tropical temperatures expected by 2100.

“In the tropics, many species appear to be living at or near their thermal optimum, a temperature that lets them thrive,” said Joshua Tewksbury of the University of Washington.

“But once temperature gets above the thermal optimum, fitness levels most likely decline quickly and there may not be much they can do about it,” he added.

Although some species might be able to migrate uphill and towards higher latitudes, or evolve to cope with the warmer climate, others might eventually die out, the scientists said
