CRAZY JETPACK

Don't go with the name. There is a jet pack but it is not crazy. This is my second project and first game project in second year of engineering.

In this game I have made this game using Java applets and I have used only graphics that are available in java.awt package except where jet pack is the image. Not that attractive or not that much of graphics. Easy to play and very user friendly. Just press up navigation key on the keyboard and the man with jet pack will move up, and on the release of the key it will come down due to gravity. Red coloured blocks are the obstacle that approach you and you need to dodge them. Black coloured blocks are the buildings that I have shown as background. The game starts in day time which can be observed with a sun and there are birds that fly in the sky. After certain period of time it becomes night that can be observed with moon and stars. In night the building colour changes to light Gray. Small yellow oval and green segment resemble street lights.Every second you move ahead score increasing. Depending upon the score speed of the obstacle approaching you increases and is displayed on upper right corner of the applet. Name of the game blinks in red and blue colour in upper left corner. If you bang a obstacle the game ends. I have used double buffer technology so that there is no blinking or flickering of the applet window when repaint function is called. Below are the few snapshots of the game.

Day time: Sun, birds, black blocks are the buildings and red block are the obstacle.

Night time: Moon, stars, grey blocks are buildings, green segments and small yellow circles are street light, red blocks are the obstacle

Game over

CLOUD COMPUTING

WHAT IS CLOUD COMPUTING

Cloud computing is the use of computing resources (hardware and software) that are delivered as a service over a network (typically the Internet). The name comes from the use of a cloud-shaped symbol as an abstraction for the complex infrastructure it contains in system diagrams. It lets consumers and businesses use applications without installation and access their personal files at any computer with internet access. This technology allows for much more efficient computing by centralizing data storage, processing and bandwidth. A simple example of cloud computing is Yahoo email, Gmail, or Hotmail etc. All you need is just an internet connection and you can start sending emails. The server and email management software is all on the cloud (internet) and is totally managed by the cloud service provider Yahoo, Google etc.

Cloud computing is broken down into three segments: "application" "storage" and "connectivity." Each segment serves a different purpose and offers different products for businesses and individuals around the world. Cloud computing always has a purpose. In simple words, this purpose is the service. Every service is realized through the application.  Optimization of the application is based the actual coding of developers. Through extensive testing on load handling, security and functionality, the application could work as expected. Everything that the application knows and the functions that could be provided by service are possible through storage. The storage holds pertinent data and information on function on how they will be implemented. And all these components will be impossible without network which gives connectivity to the cloud system.

Cloud computing providers offer their services according to three fundamental models namely Infrastructure As A Service (IAAS), Platform As A Service (PAAS), and Software As A Service (SAAS). IAAS is the most basic and each higher model abstracts from the details of the lower models. Based on the information shared, a cloud can be public, private, community or a hybrid cloud.

There are many advantages a company would have if they would consider cloud computing as part of their business plan. Among them is ease of operations. Every employee will be able to have access to the system wherever they are. Another advantage is the ease of troubleshooting. There is no need for every user to wait for their turn to have their application fixed. There is also the monetary consideration in cloud computing. Instead of tedious work with local connections and additional infrastructure, a company would just consider a cloud computing vendor which will ensure uptime of the processes.

On the other hand, there are disadvantages the company would have when they opt to use cloud computing. The biggest of them all is security. Since cloud computing uses the power of online connectivity to handle processing requests, the data could be available for everyne and could be used for malicious purposes. There is also the challenge of the end-user connectivity. Cloud computing will only be possible if there is a strong internet connection. Cloud computing might not work in areas where internet connection is weak. Infrastructure is also a challenge for cloud computing. A company who opts to have their own server would have to ensure the infrastructure will be able to deal with consistent and massive data and processing requests.

From this, it is evident that cloud computing can bring enormous benefits to IT and Business sectors. Thus, we shall see its features varying from the characteristics till applications in the chapters to follow.
