Final Project Description

Topic: A Ball Game with a Physical Engine. The Engine can simulate some real world’s physical rules such as collision, gravity and friction.

My university thesis has a similar theme. The project is a crude product, only show the physical rules between balls and world. And lack of the pretty interface. I want to improve this program. The engine is too simple for a simulate world, it can only process the collision between sphere and plane. When the project is complete I want that any kinds of polygons can collide each like in real world. (Also the world of the game should be beautified)

I plan to use XNA to develop the project (XNA has many powerful features on game development.) and seek to find some useful information about the physical engine.

Msc a new step stone.

By learning in collage for four years, I feel it is not enough for my career and future life. My english is still so pool and the skill about programming is still lack of experienced. By this status it is very hard for me to find a securing job in the society, wherever domestic or abroad.

I choose master degree not only for more studying but also for preparing. In the future year I can not only need learn for some new skills and knowledge, but also need to strength my experience and the skills of the knowledge already be learn . This year is not only for learning, also let me can have a good preparing for my future.

The world is not need a person knowing everthing, it wants someone master in their area.

The Future of Cloud Computing

What is Cloud Computing

Cloud computing is Internet-based computing, whereby shared resources, software, and information are provided to computers and other devices on demand, like the electricity grid.

With the network every user can use the open resources to complete their own calculate. The cloud computing will let the whole network looks like a huge computer and the clients are only need output & input devices.

Most cloud computing infrastructures consist of services delivered through common centers and built on servers. Clouds often appear as single points of access for all consumers’ computing needs. Commercial offerings are generally expected to meet quality of service (QoS) requirements of customers, and typically include service level agreements (SLAs). The major cloud service providers include Microsoft, Hewlett Packard, IBM, Salesforce, Amazon and Google.

LITERATURE REVIEW

John Hagel III and John Seely Brown think the cloud have some disruptive potential which will play four distinctive but overlapping waves:

The first wave of disruption focuses on new ways of delivering IT capability to enterprises that will be very challenging for traditional enterprise.

The second wave of disruption concentrates on the emergence of fundamentally new IT architectures designed to address unmet needs of enterprises as they seek to coordinate activities across scalable networks of business partners.

The third wave of disruption will be a restructuring of the technology industry as vertically integrated could service providers begin to focus on different layers of the technology stack.

The forth ,the most important one is companies will begin to harness cloud computing platforms to disrupt an expanding array of industries with fundamentally new value propositions that will be very hard for incumbents to replicate.

What will make these changes happened? The authors considered there are three main elements:

New architectures emerging from cloud computing providers will help significantly scale the ability to access highly specialized business providers on a global basis from orchestrators like Li & Fung.

As these cloud platforms scale, companies will likely unexpectedly encounter resources and companies that they were not even aware existed.

Cloud computing can also provide a much more robust foundation for the creation spaces, achieving potential as individual as institutions.

At last the authors think that: It is essential for every senior management to actively engage on understanding the capabilities of cloud computing and anticipating its ability to transform the way business is conducted. Every company should ready for the storm waves of the cloud computing. Tracing out the implications for what capabilities their own company will need to acquire or develop to compete effectively in this changing environment.

Conclusion

The cloud computing are not suit all kinds of business. The large business need security and confidentiality. The open resources based cloud computing does not easily support business-critical applications, and private networks are often rigid and static(1). With the high quality calculation the cloud computing may have much weakness around its own structure.

The cloud computing is much suit for the personal users and small business users. Most people think: ”By 2020 people won’t do their work with software running on a general-purpose PC. Instead, they will work in Internet-based applications such as Google Docs, and in applications run from smart phones…”(2)And “All of the services or programs which sent over an Internet connection can be considered a cloud service. An outside vendor runs the servers and software, so the buyer doesn’t have to worry about the technical issues in-house—and can focus on its own business.”(3)

It shows the future of cloud computing can be accepted by most people. And many users/business can get helps from the cloud computing/services. The cloud computing will have a great future.

Memory is the fortune of everybody

<Delete> is written by the Viktor Mayer-Schönberger who is a associate professor of public policy in Harvard. In the book he show a worry about: “if we can’t forget. With the develop of modern technology, its more and more hard for us to y forget something happened, what all we done will be stored with web. People may become much cautious. Everything they say or do online may haunt them years later. And the society will suffers when people stop taking risks.”

The world need memory. Each age people are try to keep their memory. From stone to paper, from photo to video. We need keep the memory to keep us well know about the history. The memory can help us avoid some mistakes, can save time from the wrong corner. Someone has said “wisdom is the accumulation of memory.” Without the memory the human can’t progress.

But at truth the most important memory should be kept in our own mind, distant friends, lost relatives and etc. We may need share these memories with others, but a permanent stored memory is useless. The memory in harddisk may only make your life can be seen by everybody. your life will not belong to yourself, may be follow your blog someone can live just like you. No one want their own life look like this, everybody wants theirslves’ freedom. Too many public memory may make a transparent society. Finally the people can only do the things cautious, every small mistake will be memorized. So we need a ‘Delete’ of out public memory on the web.’Delete’ is not a forgetten of the memory. Everyone need their own secret, we just keep the memory in our own mind and share it to the people who we identify with. 

No Memory, No lives. But if everything be remembered and know by everyone the world will changed worse.
