In today's world of rapid technological advancement“expand one's financial resources”The term comes up frequently. What exactly is open source? Why has it created such a buzz in technical circles?
What is the appeal of open source software? How is it changing the way software is developed and used? Is open source software always free?
Open source software is software whose source code is publicly available and can be viewed, modified and distributed by anyone. Its appeal is that it fosters collaboration and innovation and breaks down barriers to commercial software.
Although open source software is usually free, some open source projects also offer commercial support and advanced features that users can choose to pay for to get better service.
With the growth of the Internet and the rise of the open source movement, many developers and companies have realized that open source accelerates technology iteration and community collaboration, which has led to the gradual acceptance and application of open source software in various industries.
preamble
In recent years, the term "open source" has appeared more and more frequently. Whether you are a software developer or an ordinary user, you will often see "open source" and "free" recommended headlines. So.What is Open Source? Is open source software always free? This editorial tries to answer these questions from multiple perspectives to help the average user understand the significance, potential, and risks of open source more fully.
The origin and significance of open source
1. Origin of open source
“expand one's financial resources"The concept of Open Source first originated in the 1980s. At that time, computer software was mostlyclosed source codes, the source code written by developers was not visible to the public, and users could only use the finished software without being able to view, modify, or redistribute it. Later, a group of programmers, dissatisfied with software copyright restrictions and wanting everyone to be able to view and improve the code, pushed for the "Free Software Movement". They believe that software should be a public resource for all mankind, and like scientific knowledge, anyone should have the right to use, learn, and improve it. And so."expand one's financial resources"The idea took shape.
In 1998, the concept of "open source software" was formally introduced., emphasizes making source code public and allowing others to share and modify it. This has not only fostered technological innovation, but has also given developers around the world the opportunity to work collaboratively, spurring the creation of many notable projects such as the Linux operating system and the Git version control system.
2. The significance of open source
-
Transparency and trust: Anyone can look at the code and make sure there are no hidden malicious behaviors or backdoors in the software.
-
Collaboration and innovation: Developers from all over the world can participate in project development, share ideas and code, and make software more powerful.
-
reduce costs: Companies and individuals can use it for free or develop it based on open source projects, which greatly saves R&D costs.
-
knowledge sharing: Open source projects provide learning resources, and novice programmers can improve their skills by participating in open source projects.
Common open source protocols and highlights
Open source software is not "open without rules," and developers usually choose a method for their projects.open source protocolto specify rules for use and redistribution. Here are a few common open source protocols:
1、 GPL (GNU General Public License)
-
specificities: Strict "open source" agreements. Any modified software must also be open source.
-
affect (usually adversely): If you modify the GPL-agreed software and distribute it, then you must also open-source your own code.
2、 MIT license
-
specificities：Very loose., allowing users to freely use, modify and redistribute, and not forcing open source of modified code.
-
Applicable items: Ideal for projects that want to be used and distributed to the greatest extent possible, such as the front-end framework React.
3、 Apache license
-
specificities: Users are permitted to modify and commercialize, but are required to retain the original author's copyright notice.
-
Applicable Scenarios: Many enterprise-level projects choose this protocol because it is both open and guarantees attribution rights to the original authors.
4、 BSD licenses
-
specificities: Similar to the MIT protocol, but more focused onstatement denying or limiting responsibility, ensuring that the developer does not assume responsibility for the user.
-
Application Projects: The operating system FreeBSD is based on this protocol.
Why is open source so hot?
1. Free availability and low threshold
Most open source software is free, which allows the average user to experience high-quality tools and applications without spending a fortune. For example, the well-knownFirefoxcap (a poem)VLC PlayerAll are open source projects and are completely free for users.
2、 Fast update and active community
Open source projects usually have a large community behind them that maintains and updates them. Developers and enthusiasts in the community are the first to help when users encounter problems. For example.Linux systemMany of the distributions will be updated every few months, bringing new features and issue fixes.
3. Technical transparency and user trust
Since the open source code is publicly available, users can view how it works, reducing the risk of privacy breaches and black-box operations, as seen in theData security and privacy protectionThe field is particularly important.
Is open source always free?
Many people mistakenly believe that open source software is necessarily free, but this is not the case. Open source and free aretwo concepts, there is no direct relationship between the two.
1. "Free" and "value-added services" of open source projects
While open source software is usually free to use, some projects providevalue-added service. Example:
-
GitLab: The Community Edition is available for free, but there is a fee for the Enterprise Edition, which offers more advanced features and technical support.
-
WordPress: The base code is free, but some premium plugins and themes need to be purchased.
2. Open source is not the same as "giving up commercial value".
Some companies will use open source asbusiness strategy, which profits from providing specialized support, customized services, or paid versions. For example, database softwareMySQLAlthough it is open source, its commercial version has more features and requires a fee.
3. Thinking from the user's perspective
For the average user, open source software is usually free, but it's best to understand the possible profit models behind it if you can. For example, some free open source software comes with advertisements or requires users to register in order to collect data.
Don't overly fetishize open source
While open source software has many advantages and encourages collaboration, theCode OpenIt also poses security risks. Sometimes, malicious attackers plant open source projects withmalicious code (e.g. virus)This type of behavior is known as "poisoning". This type of behavior is known as "poisoning". Common methods include:
-
Dependency Injection Attacks: Attackers add malicious dependency libraries to a popular open-source project, causing users to become infected when installing the software.
-
malicious update (computing): Attackers posing as maintainers release new versions with malicious code.
1. Cases of incidents
-
In 2018, an open source project on npm, a well-known JavaScript package management platform, was found to contain malicious code that stole users' Bitcoin wallet addresses.
2. How can ordinary users protect their security?
-
Download from trusted sources: If available, try to get open source software from official platforms (github, gitee) or other trusted platforms.
-
Focus on community evaluation: Follow reviews and feedback from other users and choose to maintain active programs.
