Cook talked about the iPad as “the poster child of the post-PC era.” Technology is rapidly changing and iPads are becoming increasingly important in education, as we have already blogged about. Apple has in fact sold 15.5 million iPads during the last quarter. Cook said: “We’re talking about a world where the PC is no longer at the centre of your digital world but rather just a device. We’re talking about a new world where the devices you use the most need to be more portable… and dramatically easier to use than ever before.”

Spanish? It’s the second most natively spoken language in the world, the second most studied and the third most commonly used on the Internet, after English and Mandarin. This is still not the journalist’s choice.

Mr. Greene picked French. The Francophonie is an organisation which brings together 56 member states and governments that have a French-speaking heritage, which means almost one third of the world’s countries. Moreover, France attracts more tourists than any other country—76.8m in 2010, according to the World Tourism Organisation.

ABC News wrote that the top three most useful languages for business after English are Mandarin, French and Arabic, with Spanish ranking fourth.

English native speakers don’t learn foreign languages: after all English is not only the first language of some countries, but it is also the rest of the world’s second language. Nonetheless, learning a foreign language produces a cultural awareness that can be useful in business as well as in personal affairs. For example, a capable linguist makes a huge difference when negotiating.

GreenBulb is now supporting an interesting project for a 3D printer called MakiBox, so that some of the prototypes can be made in house. This project is being advertised on Makible, a fund raising site specialising in manufacturing and distribution. Makible guarantees that successfully funded projects will be made in a sustainable and responsible manner, that supporters will receive their funded products according to the arranged deadlines or they will be refunded and that profit will be fairly shared with the makers.

The MakiBox A6 is able to print out something that is 1/4 the size of the printer itself, but it is still only the size of a sheet of paper. We have already blogged about Additive Manufacturing, and MakiBox is a step forward in its development. It can be a useful tool for makers, designers, students, engineers and anyone that wants to make things they can’t find in a store.
