True Longtail Rule

True longtail rule is the combined rule of longtail and 1% rules. This rule is the technical and economical rule.

Gauss's theorem

Sometimes, the principle of ecosystem extends to the object-economy theory. Gauss's theorem is a representative strategy of competition which borrows the fundamental truth within ecosystem . Today, I will give you an explanation about Gauss's theorem. Gauss, a Russian scientist, conducted two experiments. First, he put two animals in same space whose family was same but species were different. Their nest was conditioned to have insufficient food. He observed what would be going on inside the small room. Despite occasional quarreling, two animals managed to survive, sharing short meal. Second, he performed an identical test of same family and same species. However the result was completely different. They fought severely and knocked to death each other. Gauss called this phenomenon the survival principal by differentiation. The more similar they are, the more they fight. Consequently, being alike demands intensive competition among contestants. For additional knowledge, there is

The nature of cooperation

Yesterday night, a friend told that people usually cooperate well with an new comer or unfamiliar person rather than an intimate neighbor. It reminded me of one Korean proverb : I am jealous of neighbor´s success or An envious man waxes with the fatness of his neighbor. The more we appreciate these witty remarks, the more we are disappointed with selfishness of human being. So, some people tend to be pessimistic about a cooperative attitude between A & B. If we always have a competitive spirit to the core, is cooperating just false? Another friend had an answer. His view point is very clear and accurate. He announced that we should accept the jealousy within people. However, since we are based on a sense of selfishness, we try to maintain the peaceful achievement. Because,we do not want to harm the job or the relationship we are related to. And he said it will open the way to a cooperation. I think second friend also took a gloomy view about people. But he has an ability to transfo

Network MIMO

What is network MIMO?

Cooperation for wireless network

Up to now, wireless networks has been developed to make users compete each other. For instant, the user scheduler in the cellular network selects the user whose wireless channel is the best of all. Therefore, each user report his status as accurate as possible. He doesn't care other user when he report his channel quality. Even though his channel is good, if he continuously report his good channel quality, the other use whose channel is worse will receives much lower speed data. Consider the case the high quality user becomes in bad condition, his receiving performance will be also bad. Therefore, we need some cooperation to avoid this phenomena. One emerging way to avoid this inequality is to use cooperative diversity.

Competition vs. Cooperation

Competition has been important for development up to now. However, humans who are able to cooperate with others were always better than ones who are not in terms of his success. Cooperation is not easy task for human being since we are always selfish. However, wise-man knows that cooperation will give much more gain than always to be in the competition mode.
