SunSolaris10 plans to open 10 million lines of source code

Article title: SunSolaris10 plans to open 10 million lines of source code. Linux is a technology channel of the IT lab in China. Includes basic categories such as desktop applications, Linux system management, kernel research, embedded systems, and open source.

Despite years of history in implementing open-source products, Sun announced last year that it would open-source its flagship product, Solaris, which suddenly showed people a completely open-source Sun with consistent words and deeds. simon Phipps, CEO of Sun software open source, said: "Solaris is Sun's first software that has been successfully transferred to the service billing model. in the future, all Sun software will be transferred to this model. Now Solaris has a very successful start: first, the revenue from training is increasing. Second, we see an increasing number of downloads and licenses for other hardware platforms ."

In the last year alone, more than 14000 people joined the OpenSolaris open-source community, and OpenSolaris had five new independent release versions. What's more, many people put Solaris on FreeBSD and Apple's OS/10. All these positive signs indicate that OpenSolaris is truly open-source and healthy.

Unlike Linux's GPL protocol, Solaris adopts the CDDL protocol. Compared with GPL, the CDDL protocol has three major advantages: first, when applying Solaris, ISV does not have to ask for feedback on its R & D or labor results. they can choose not to disclose their source code, retain your intellectual property rights, thus reserving development space for software companies. Second, Sun allows ISVs to apply all Solaris-related patents free of charge and there is no potential legal risk. Third, many other protocols are first restricted by US law, while CDDL allows users to resolve them according to local laws. For example, if Chinese ISVs have a legal dispute when applying Solaris, they can be resolved in Chinese courts and are in accordance with Chinese laws.

For Solaris 10, Sun plans to open source for 10 million lines of code, and remain the same for those involving third-party drivers. Simon Phipps said, "the version control function was not open to the public in the past, because the Solaris version control uses teamware, which is not open to the public. Open version control has a great impact on the development of the entire community ." This message will undoubtedly stimulate more ISVs or individuals to perform secondary development on Solaris.

Open-source quotations:

Open source is Sun's core strategy. this year, Sun will launch a series of moves around the world, including open-source Linux, ODF, Java, Solaris, and other initiatives. Sun believes that open source is a complete concept. a community works around the foundation of a code, which requires a common open source protocol, at the same time, there must also be a community's organization and operation rules, both of which are indispensable. Therefore, Sun should not only open-source Java, but also operate the Java community well. The open-source world is now very rich. at this time, it is critical to provide users with a unified programming mode and an environment. Historically, Sun decided which license to use based on the characteristics of every software or community. for example, openiscsi adopts the GPL protocol and OpenSolaris adopts the CCDL protocol. This gives Sun an open market. Sun believes that all software will develop into this model in the future. Solaris is Sun's first software that has been successfully transferred to this mode. in the future, all Sun's software will be transferred to this mode.

-- Simon Phipps, Sun's software open source chief executive

We hope Sun will become an open-source company, a network company, and a company that leads the development of the global software industry. Sun has become the first open source vendor in terms of the number of lines of open source code. Solaris is the core of Sun's software strategy. in the software and software platform field, what platforms are most important for developers to adopt, now more developers have begun to adopt Sun's platform, which is what Sun's open source can achieve. It can be said that while continuing to open source software products, Sun has won more and more partners and developers, and this is the new impetus that open source brings to Sun.

-- Sun Executive Vice President Rich Green

On the whole, we are very pleased to announce Sun's open-source Java concept and are very supportive of this action. IBM supports all open source licenses recognized by OSI. There is already an important open-source achievement, that is, working with Sun to create a Java-compatible Java SE implementation in Apache Foundation, that is, the Harmony Project.

-- Rod Smith, vice president of IBM Internet technology

The more open source Java is, the better the effect will be. I think Sun's open-source Java is quite different. I don't think people sitting next to the fence will make decisions on which open-source Java project to build. I think we will share the results of donors fairly. "

-- Harmony Project chairman Geir Magnusson
