April 20 2010 Categorized Under: Electronics one Commented

A previously little-known company from the UK called Light Blue Optics has demoed a projector at CES which allows users to interact with the light image as if it were a touchscreen.

The Light Touch throws a 10-inch image at WVGA resolution at incredibly short distances thanks to the holographic projection technology involved. At the same time the infra-red touch sensitive system allows users to interact with social networks, multimedia sharing and any other applications that can use the Wi-Fi or Bluetooth support in the device to connect to the Internet.

It comes with 2GB of onboard flash memory, a microSD card slot for expanding the storage and the battery life will last 2 hours. Expect to hear more from this one on the OEM front as interest grows.

The Top 10 Internet Scams for 2009 – predicted by E-Victims

1. Identity theft and phishing – The black market for financial data on individuals is well established. Criminals try to steal your personal data using different techniques; phishing, social networks, telesales, hacking into websites, setting up bogus websites etc. Don’t share unnecessary personal data with websites. If they insist on your date of birth, post code etc. – don’t use your real ones.

2. Viruses and spyware – They are everywhere. It is impossible to know if you are visiting an infected website. If you download a pdf, it may or may not be infected. If you view a YouTube video, watch a flash ad, they may infect your computer too.

3. Advance fee scams – Nigerian and lottery scams have also been around for years, but they still work. There maybe a hundred variations to these scams but they are all basically the same. They offer a large sum of money, but there is always a fee to pay before you get it.

4. Work at home and job scams – These scams have been around for years, but rising unemployment will mean that we expect more scams targeting vulnerable job seekers.

5. Fake or spoofed websites – Phishing, domain hi-jacking, posting in forums are just some of the ways criminals attract you to their fake sites. These bogus online retailers offer a great deal, or impossible to find items, to attract victims. They set up a site for a short time, then shut it down only to set up a new site and do it all over again.

6. Economy related scams – Loan and debt consolidation scams have been increasing throughout 2008. There will be new ones look out for, including repossession assistance and unemployment insurance.

7. Classified ads and auction scams – Scammers use local online classified ads, CraigsList etc. to find new victims. Then they contact sellers with fraud cheque scams, offering to buy something or rent a room. They send a cheque for more money than agreed, with an excuse as why you should send the extra money back to them or their friend. The cheque is a fake and they hope you wire the money before you find out.

8. Holiday Scams – Can’t afford a great holiday this year? Well the scammers know the credit crunch has hit the holiday budget. So, they are advertising some incredible deals. Unfortunately, the deals aren’t real.

9. Ticket Scams – We saw large scale ticket fraud with the Beijing Olympics. Criminals are producing counterfeit tickets for concerts, festivals, football games and other events. They sell them online via auction sites, classified ads or by setting up their own website.

10. Social Networking – A hot scam is sending messages that tell someone they are in a You Tube video or mentioned on Twitter. When they follow the link their computer gets compromised. Dating scams, hacked accounts, conmen that contact friends and family claiming they are in trouble and need money – these are some of the most popular scams we see with social networks.

Turn2Live: Concert Search Engine Based on Your Mood

April 6 2010 Categorized Under: Web sites 2 Commented

Turn2Live is a new concert search engine that aims to help you find concerts based on your mood. Turn2Live is still in beta testing which means they are only offering listings from Austin, USA. The concept itself is very interesting, but it is so difficult to properly categorise artists and specific tracks to an exact mood, as certain songs will mean different moods to different people.
