David Braben is a very well­known game developer who
runs the UK development studio，Frontier Developments，but is
just as well­known for being the developer of “Elite”．
Over his career his studio has brought us the“Rollercoaster
Tycoon”serie s and most recently “Kinectimals”. In the
background，however，Braben has been trying to solve another problem: getting programming and general learning of how computers work back into schools.
Braben says that education since we entered the 2 000s has turned towards teaching useful skills such as writing on computer, how to get information, and learning basic computer use skills. And those have supplanted more computer science ­like skills such as basic programming and understanding the hardware(硬件) contained in a computer.
His solution is not to create his own course，but instead to make a low­cost PC that can be given to kids for free and his courses are built up around their use.A personal computer is important for each student to have in class.When we say “low cost”，we mean the cost is so low that even “One Laptop per Child”would be realized.Braben has developed a tiny PC.How much is the cost? $25.This is the answer to anyone that says he/she can't afford a computer.The hardware being offered is good，too.The new tiny PC will let the user look through the Internet and give the
user a fully functional (功能) computer to play with.And it can be carried in your pocket or on a key chain.
This tiny cheap PC is going to be given to schools through a new charitable foundation (慈善机构) called the Raspberry Pi Foundation.It will help computer science studies in schools.Braben says he hopes that they will be given within the next 12 months.

The world's biggest Internet search engine，Google，has proven once again to be king of the ers can download“Google Wi­Fi”software and then enjoy free Wi-Fi service available in some US cities since last Tuesday.
Wi­Fi is short for “Wireless Fidelity”(无线上网)．It allows laptop computers and personal digital assistants to connect to the Internet at high speed by radio signal.
A person with a Wi­Fi enabled computer can connect to the Internet when near one of the network's access points.The place covered by one or several access points is called a hotspot.Google has already set up two “hotspots”in the US city of San Francisco which provide a free Wi-Fi service.
The Wi­Fi technology even allows users to enjoy a free Internet phone service.Some scientists argue that Wi­Fi may replace mobile phone networks.
Wi­Fi is still limited to a few cities，where there are “hotspots”．But its capability(容量)of sending information has already done better than that of the mobile phone network，even that of 3G (3rd generation telecommunication technology)．Some scientists have started to call Wi-Fi 4G.
In addition to a high speed Internet connection，Wi­Fi has other advantages compared to mobile phones.Wi­Fi is global.The same Wi­Fi system works in different countries around the world.Different from using cell phones，you don't need to change computers to use Internet phones when you go to other places and most
importantly，many Internet phones cost you nothing at all.
