For those who don't know yet what cloud computing is, let me explain it first. Cloud computing is actualy just running your own server virtualized. This means you have a virtual server on a computer somewhere else. It doesn't realy exist, it's just logical and not physical. The advantage is, you don't have to invest in new hardware, although you have to pay rent for the resources you use from your provider. It comes in very handy if you don't want to make a big investment right away or if you don't have the room for your own server. This way it's all a lot simpler. Just rent a virtual server and they take care for everything. Mostly you can check the hardware status and up- or downgrade any moment and this in just seconds. You don't need to go buy the hardware first, it can just be added right away. Others think it comes in handy for when there is something wrong with the server, when this happens, your server just gets moved to another computer and is imediately back online.

Johnny Lee's own view
Hi, I found this cool video about how Johnny Lee can make all these cool things with a wii remote. He can make a whiteboard, a touchscreen and even 3D-glasses with this cheap thing. All these things recquire some software or some aditions, but they are all so simple and easy to use. I think for any further information, just go to his page and watch this video.

Bitcoins
What is bitcoin?
A bitcoin is a online currency, like the USD or the EUR, except, you can't hold a bitcoin. The only difference is that you can't hold a bitcoin and you can't pay everywhere with thelm. Although some companies accept bitcoins, mainly online companies. So you can't go shopping in the city and start paying with bitcoins.
Bitcoin is created by a programmer or group of programmers, this still remains a mistery, known as Satoshi Nakamoto and it has been around since 2009.
If you want a bitcoin yourself, you need to buy one online, there are several sites for it, like tradehill or Mt. Gox. You can also get one by "mining", this way your computer is gonna check with a mathematical process if a hidden series of letters and numbers match with an unclaimed bitcoin. Now this ain't that simple anymore, all the simple combinations are already claimed. These days serious miners have multiple computers running to search for the right combination. There are even viruses on the internet that makes your computer a slave for them so they use your computer to mine for them.
The bitcoin doesn't have a fixed value, it changes all the time. If you realy want to know what the bitcoin is worth at the moment just go to http://bitcoincharts.com/ here you can find all the information about bitcoin and it's exchange.
