Open-source framework for thinking about [3]



Not for the best but to apply

Developers are often a perfectionist, picky, with a strong paranoid tendencies. Yes, paranoia is a characteristic of good programmers, nowadays, "only the paranoid survive" is also big selling Hot, Rod Johnson, Gavin King, Oberg are also paranoid.

But there is progress in the duration of the pressure, we had to achieve a compromise. For companies, profits are always the first one, no matter what with no frame or framework, as long as the quality and quantity on schedule to complete all of the features users demand, is the best project. Customers never see, nor do they care what you use the best technology and framework.

Therefore, the actual development, we may often need to compromise in these impulses, as long as the current framework to meet the demand, we do not have to rush to recover the same as the fashion industry fashion, all does not demand the best, but to apply.

If Spring Template JDBC has been very good to meet the current demand, it does not necessarily need the Hibernate, if they develop a brief list controls work well, it does not convert ExtremeTable. Cost of the new framework of learning needs, but the price effect to play before the actual value is not positive. What may seem simple and old obsolete technology that can make a powerful system, such as the world's largest java project - Brazil national health care system is built on top of JSP + JavaBean + Servlet.

Focus on building a platform

We often find themselves without any accumulation of software companies, fully integrated framework hopes to solve all these problems. Are open source frameworks to solve common problems in one area, in which each company because of its industry, service users different, requiring the company to have their own solution, a common framework and the company's individual needs are conflicting of.

Software companies should strengthen their own accumulation, based on the framework in these structures better suited to their own Xuqiu the rapid development platform, shielding out the underlying framework Fuza features and minutiae, lower right development of skilled workers, so that staff can quickly participate in the Xin Xiang Mu in, without the need for an open-source framework for learning.

Although this accumulation and platform construction will cost an additional workload, but first it is a gradual process, then this task is only two or three technique by the outstanding technical staff commitment, the benefits of a direct reduction of other development use by degree of difficulty and technical requirements, certain procedures to avoid the open-source framework for the instability caused by impact.

4 Summary

A rich source of prosperity of the framework, a strong promotion of the industry's development, and we have seen, this prosperity has brought a surprise behind the eyes followed by Zhao Xu Duo confused, lost in the chaos of prosperity among the Kai Fa had hoped out of the confusion out of the puzzle.

How in the noisy bustle of the open source world to grasp the direction of seeking a breakthrough, whether developers or software companies for decision-makers are worth thinking deeply.

CPU chip with independent intellectual property rights through the acceptance of Godson 2E


Yesterday, the ICT projects undertaken by 863 "Godson-2 processor chip design of enhanced" (Godson 2E) through "15", 863 information technology expert group acceptance. Science and Technology Minister Xu Guanhua said at the meeting in the acceptance, the success of the project, shows that China has taken a key step in the information field, and he stressed that the development of high technology and industrial development must be closely integrated.

Godson 2E2005 project started in May, March 17, 2006 get the Godson 2E chip parallel transfer success, May 23 863 expert group organized by the test.

In a live demonstration, the prototype uses 64-bit Godson-2E Linux operating system, can smooth running Mozilla browser, OpenOffice office suite, Mplayer media player and other streaming applications, and can properly support Chinese input and display. Group believes that the chip is used in mainland China the first 90-nanometer processor design, the maximum speeds up to 1.0GHz, the peak computing speed of 4.0 billion times per second, double-precision floating-point operations, has been in the single-processor design reached the international advanced level, is the CPU chip with independent intellectual property rights.

Xu said, the 863 program started 20 years ago, China played a key role high-technology development. "Eleventh Five-Year Plan" period, China will further promote the development of high technology and industrialization, where two levels. First of all, 863 major projects, key projects on the basis of a breakthrough good demonstration of the transformation of traditional industries, to contribute to the formation of new industries; In addition, some aspects of technical reserves for the shortage, the state has given great attention encourage experts to explore the establishment of objectives for more. We have also established a "special study" in the hope of young people by supporting innovative ideas, cultivate a group of young scientists, the scientific development of China's future to make the necessary reserves.
