Wolfram Alpha develops pricey new iPhone app

The developers say that the new app is a lot more powerful than the website and is a load more easy to use too. It also has some innovative features like a joint QWERTY/numeric keypad, which bearing in mind that a lot of WA queries involve both numbers and words, makes perfect sense. Other facilities include the ability to optimise the app to suit your location, the option of bookmarking queries and easier emailing or sharing of queries.

Amplichoir – sing Lollipop and win MTV EMA VIP tickets, maybe

Dell and MTV have joined together to produce Amplichoir. The idea is simple. You record yourself singing Lollipop (the music used in the Dell adverts of course) using a webcam and microphone and you can see and hear yourself by clicking on a thumbnail on the home screen.

Billed as the world’s biggest karaoke, it’s so far attracted around 500 people to participate. The incentive for people to take part – apart from the chance of singing a naff, but very catchy, song out of tune? The chance to win VIP tickets to the European MTV Music Awards and afterparty in Berlin on November 5th.

The prize includes flights and accommodation for you and a friend, stretch limousine transfers to and from the airport and awards, champagne and flowers in your room when you arrive, dinner for two at Fischers Fritz (the only 2 Michelin Star restaurant in Berlin), a relaxing massage in the Regent Spa, make-up/hairdresser to get you looking good for the awards and after-party, and an EMA Award presented to you on the red carpet. So what are you waiting for? Time to dust off that miicrophone and croon with the best of them.

Will Google Wave be a huge success? Five problems it will have to overcome

Although it has many unique features people are already using web based tools and sites to make and share documents. In a very basic way there is a great deal of collaboration already going on via Facebook, Twitter and even MySpace, while at the more corporate end of the spectrum are several excellent collaboration tools already such as the UK's very own Huddle. Then of course there are already millions of people across the globe using Microsoft's collaboration tools.
