What is open source software?
Open source software refers to software whose source code is public and can be freely used, modified and distributed, usually under an open source license (such as GPL, MIT, Apache). Users can review the code, contribute improvements or customize functions.
Is open source software free?
Most open source software is free to use, but "free" means freedom, not zero cost. There may be costs for support, maintenance, or commercial versions. Companies may pay for the deployment or services of open source software.
Is open source software safe?
Open source software is theoretically safer because its code is transparent and vulnerabilities can be quickly discovered and fixed by the community. However, security depends on the activity of the community, maintenance frequency, and user configuration. Inactive projects may be risky.
What is the difference between open source software and proprietary software?
Open source software: The source code is open, can be freely modified and distributed, and is subject to open source licenses.
Proprietary software: The source code is closed, users can only use it, not modify it, and need to purchase a license.
Open source emphasizes community collaboration, while proprietary software is controlled and developed by companies.
Who maintains open source software?
Open source software is maintained by developer communities, volunteers, companies or foundations (such as the Apache Software Foundation, the Linux Foundation). Large projects (such as Linux, Apache) are often sponsored by companies.
Why do companies support open source software?
Companies support open source to reduce development costs, accelerate innovation, attract developer talent, build ecosystems or promote related services. For example, Red Hat makes money through support services, and Google expands its influence through Android.
What are some common examples of open source software?
- Operating systems: Linux, Ubuntu
- Browsers: Firefox, Chromium
- Servers: Apache, Nginx
- Development tools: Git, VS Code
- Databases: MySQL, PostgreSQL
How to participate in open source projects?
- Beginner: Read documents, report bugs, and submit small fixes.
- Developers: Contribute code and participate in discussions, using common platforms such as GitHub and GitLab.
- Non-technical staff: Translate, write documents, and promote projects.
It is recommended to start with projects that interest you and follow the community contribution guidelines.
