5W1H of Open Source Software. Examples , Top Projects, Advantages and more about Open Source

Update Date: 01.09.2023

A sort of licensing arrangement known as "open source" permits users to freely change works, use them in new ways, incorporate them into bigger projects, or create new works based on the original. Open source encourages the free exchange of ideas within a community to foster growth in the arts, sciences, and technology by reducing barriers between innovators. Open-source software encourages creativity and original thinking. The foundation of open-source is teamwork. Code that is open source is freely accessible to the public. Everyone has access to opportunities. To contribute to open-source, you don't need a degree, a certificate, or a GPA of 4. Each of these explains the significance of open source.

Many people have asserted that the open-source movement began with the advent of the Internet in 1969. However, some people do not distinguish between free software and open-source movements. In actuality, MIT programmer Richard Stallman started an unofficial campaign in 1983 that had the aim of making source code freely available. Stallman thought that software should be available to programmers so they could alter it as they pleased to comprehend, discover, and enhance it. Stallman started disseminating open-source software under his own GNU Public License. The Open Source Initiative was established in 1998 as a result of the new methodology and mindset that had become prevalent in the software development industry. Eric Raymond and Bruce Perens founded the Open Source Initiative (OSI) in February 1998.

In 2001, even major corporations like Microsoft started creating official open-source websites. Just a handful of the businesses having large public stakes in today's fiercely competitive open-source industry are IBM, Oracle, Google, and State Farm.

The use of open source software is common. Many free and paid products employ open-source software, which is developed and maintained by a community of volunteer programmers. The Apache HTTP Server, the e-commerce platform osCommerce, the web browsers Mozilla Firefox and Chromium (the project where the great bulk of development of the freeware Google Chrome is done), and the entire office suite LibreOffice are notable examples of open-source goods. The open-source GNU/Linux operating system and its derivatives, an operating system for mobile devices, are two of the most popular open-source products. Open-source software is standard practice in various sectors.

Throughout this article, we will go over what open source software is and the well-known examples, how open source software works, why we use open source software, who owns open source software, the advantages of using open source software, and the challenges with open source software. Additionally, we will discuss the distinction between free and open source software and why open source is preferable to proprietary or closed-source programs. We'll finish by responding to the following queries:

• Is Java Open Source?

• Is Android Open Source?

• Is open-source software safe?

• What is an open-source software license?

• What are the Open Source Software License Types?

What is Open Source Software and What are the Well-Known Examples?

Open-source software (OSS) is computer software containing source code that is distributed under a license that provides users the right to use, study, modify, and distribute the program and its source code for any purpose. A broad software license is known as "open source" makes source code available to the entire public with few or no limitations on its usage and modification. The development of open source software is decentralized and collaborative, depending on peer review and community contribution. Because it is produced by communities rather than a single author or organization, open source software is frequently less expensive, more flexible, and more durable than its proprietary counterparts.

Most computer users never view the source code, which is the portion of the software that computer programmers modify to determine how a program or application operates. A program can be altered by programmers who have access to the source code by adding to it, altering it, or fixing any problematic sections. In order to facilitate the quick evolution of the program, it turns a piece of software into an open source project with few restrictions on its usage or distribution by any company or user.

Something being "open source" doesn't merely mean it's free. The application must allow the dissemination of the source code as well as the built version. The desired format in which a programmer would alter the software must be included in the source code. It must be possible to distribute derivative works and modified versions of the software under the same conditions as the original software. The distribution of software created from modified source code must be expressly permitted by the license. There must be no bias against any individual or group of individuals in the license. Additionally, the license cannot prevent someone from using the program in a certain industry. It might not prevent the application from being utilized for genetic research or in a commercial setting, for instance. The rights associated with the program must apply to everyone to whom it is redistributed without the necessity for those parties to execute an extra license. All parties to whom the program is redistributed should have the same rights as those that are provided in conjunction with the original software distribution if the program is extracted from that distribution and utilized or distributed in accordance with the license's terms. Other software that is delivered with the licensed software cannot be subject to restrictions imposed by the license. For instance, the license cannot mandate that only open-source software may be used to distribute additional applications on the same medium.

Last but not least, no licensing clause may be based on a specific interface or technology.

Drupal Association, FreeBSD Foundation, Linux Foundation, OpenSUSE Foundation, Mozilla Foundation, Wikimedia Foundation, WordPress Foundation, and Debian, are the largest open-source software initiatives in the world.

How Does Open-Source Software Work?

In the software development community, open source has played a significant role. Indeed, a generation of open source tools has been developed and is currently being utilized by developers to help improve and troubleshoot open source code throughout the early stages of software development.

Open Source Software(OSS) is frequently shared extensively and stored in a public repository. Anyone with access to the repository can use the code independently or add to its overall functionality and design.

On GitHub, SourceForge, Launchpad, and other similar websites, you may access repositories and take part in community projects for a variety of open source projects.

OSS frequently comes with a distribution license. This license outlines the rules for the program's use, analysis, modification, and most importantly distribution.

When source code is amended, OSS must document both the changes and the techniques employed. Depending on the licensing terms, the software that results from these modifications may or may not be required to be made freely available.

Why Do We Use Open-Source Software?

There are several reasons why people or businesses adopt open source. These are the top six benefits of open-source software:

• Open Collaboration: The emergence of vibrant open source communities means that you can access assistance, materials, and viewpoints that go beyond a single industry or business.

• No Vendor Lock-in: Open source software is portable and usable at any time for any purpose.

• Flexibility: Because open source code places a strong emphasis on modification, you can utilize it to solve issues that are exclusive to your company or neighborhood. You aren't forced to use the code in any particular way, and you may rely on peer review and community support when you put innovative solutions into practice.

• Reliability: The upkeep, maintenance, and operation of proprietary code is the sole responsibility of the individual author or entity in charge of it. Since open source code is frequently updated by vibrant open source communities, it outlives the original authors. Open source software is regularly and appropriately tested thanks to open standards and peer review.

• Transparency: Do you need to know precisely what types of data are being sent or where they are going, or what changes have been made to the code? Without having to rely on vendor guarantees, open source enables you to examine and monitor that for yourself.

• Peer Review: Since the source code is publicly available and the open source community is quite active, peer reviewers regularly check and update open source code. Instead of a closed-off, stagnant code, think of it as a living code.

Who Owns Open Source Software?

Typically, the developer of an open-source project owns the software but grants other "contributors'' permission to replicate, modify, and redistribute it. The licenses provided to software providers and consumers are frequently standardized (see MIT, GNU LGPL, and Apache as examples). Contributors must typically make their modifications to the software (or updates, alternate versions, or derivative works) available as open-source as well. For example, the popular open-source search tool Elasticsearch can be modified by contributors, and licenses to use the modifications made by the contributors are available to the community, but the creator of the original Elasticsearch software and the contributors all retain copyright to the parts of software that they created.

Both the developer and contributors to open-source software have the option of assigning their copyright to a single person or legal body, most typically an open-source foundation. This has many advantages. For starters, it simplifies copyright enforcement because there are fewer parties engaged in each dispute with only one copyright holder. It can be difficult to determine how to comply with all of the licenses issued if varying licenses govern a piece of code when several people hold separate copyrights over different elements of the same software. Assigning copyrights to a single entity also reduces the possibility of contributors changing the license they grant for their contribution to the program after a subsequent contributor relied on a previous license. This may cause legal complications for future contributors who were not told of the change.

Organizations such as the Open Source Initiative (OSI) operate as watchdogs, approving these standard forms of license as suitable for promoting open source projects.

What are the Advantages of Using Open Source Software?

Today, using open source software has become indispensable. This is because using open source software has many advantages. We can list these advantages as follows.

• Since open-source software is typically simpler to access than proprietary software, usage tends to rise.

• Software that is open source is free. Additionally, fewer marketing and logistics services are required for OSS. The OSS development methodology has made it possible to create dependable, high-quality software fast and affordably.

• A built-in community that supports open source constantly edits and enhances the source code. Due to this, open-source development has the ability to accelerate creativity, the production of innovation, and the creation of social value. For instance, a French government incentive program encouraged the use of free open-source software, which led to an annual increase of approximately 600,000 OSS contributions, creating social value by raising the amount and caliber of open-source software. Additionally, this legislation is thought to have increased the number of tech companies by up to 18% and the employment of IT professionals by 14%.

• Open source software is claimed to be more dependable since thousands of independent programmers often test and solve software flaws. Open source is independent of the organization or author who first developed it. The code will continue to exist and be improved even if the company fails. Additionally, it adheres to open standards that are available to everyone, eliminating the issue of incompatible formats that may arise with proprietary software.

• Users may rely on open source because it is stable and the source code is made available to the public because they know that the code's developers can't just stop working on the project or let it deteriorate.

• For new programmers, open source offers fantastic learning possibilities. Additionally, open source encourages creativity; programmers can use pre-existing code to enhance the product and even develop original ideas.

• It is innovative because open-source programs are the result of collaboration between many different programmers, and it is adaptable because modular systems allow programmers to develop bespoke interfaces or add new capabilities to them. Innovation is sped up by the blending of diverse viewpoints, organizational aims, and individual objectives. Developers are permitted to freely modify the code to better suit their specific needs by looking at how it functions and fixing any broken or troublesome parts of the application.

What are the Challenges with Open Source Software?

As with any technology, using OSS can present some difficulties for developers and businesses. The major issue is that it is freely available for the public to use and alter.

First of all, there are cyber attacks resulting from publicity. Everyone has easy access to the source code in the open source community. The ability to highlight any loose ends in the code thanks to this open accessibility is one benefit, but it is also how hackers exploit programs and potentially hurt their users.

The National Vulnerability Data (NVD) platform makes open source vulnerabilities accessible, which is how hackers discover and exploit code flaws. Since even a small vulnerability could result in a security breach, this vulnerability is one of the main difficulties associated with implementing an OSS solution.

Risks Every organization strives to increase production speed because of legacy code. Developers frequently reuse code that has been in use for a long time in order to expedite the development process, trusting it implicitly because of its widespread use. But given the legacy code's numerous interconnected dependencies, which may expose the application to security concerns, this is less than ideal.

There might be liability risks with open source software. In contrast to commercial software, which is entirely under the vendor's control, open source seldom includes warranty, liability, or infringement indemnity protection. This places the responsibility for maintaining legal compliance on the user of the OSS.

Due to its complicated installation and lack of user-friendly interfaces, open source may be difficult to use and embrace. Training people, importing data, and installing essential gear might incur unanticipated expenditures with open source.

Open source might offer compatibility concerns. When trying to program proprietary hardware using OSS, specialist drivers that are often only available from the hardware vendor are frequently required.

And lastly, there can be a lack of uniform license compliance. A license that comes with open source software enables users to use, improve, and edit the source code. The legal terms contained in the OSS apply to you if you are a developer or an organization using the software. However, as some licenses do not adhere to OSI's regulations, utilizing such software poses a serious security risk.

Software distributed under multiple banners occasionally complies with differing licensing requirements, and not all items issued under a given banner do so. Users find it challenging to use a variety of goods in their projects due to the lack of a uniform licensing authority, and the variances in compliance create even more vulnerabilities.

What's the Difference Between Free and Open Source Software?

Richard Stallman, the founder of the free software movement, claims that the primary distinction is that by selecting one phrase over the other (such as "open source" or "free software"), one communicates one's objectives to others: "Free software is a social movement; open source is a development technique".

Even yet, there is a lot of common ground between free and open source software. According to the Free Software Foundation (FSF), the term "open source" encourages a different form of ambiguity by conflating the right to just access the source code with the freedom to use, change, and redistribute it. However, the term "free software" has come under fire for its historical unclear meaning and the vagueness with which the word "free" has been used in the past, which was thought to discourage commercial adoption.

In summary, the difference between free software and open source software is:

• The Free Software Foundation first used it in the 1980s. OSS Philosophy The term "open source" was first used in the late 1990s to describe a movement against the limitations of free software.

• Software from FS Philosophy plays a significant role in people's lives. OSS Philosophy Software is only software, after all. It has no definite ethical implications.

• Social freedom is correlated with software freedom.OSS Philosophy Ethics should be connected to humans rather than to software.

• According to the FS philosophy, freedom is a value that is more significant than any economic benefit. In OSS Philosophy, the idea of freedom is not unqualified. Freedom ought to be granted, not forced.

• Every piece of free software is free. Every piece of open-source software is not completely free.

• There are a wide variety of open-source software licenses, some of which are very restrictive and produce open-source software that is not free. Such a problem doesn't exist in free software.

• There are no limitations placed on free software. Occasionally, users are subject to restrictions imposed by open-source software.

What is the Most Popular Open Source Software?

The first piece of Open-Source software was published in 1997. Despite the industry, almost every software now has an Open-Source alternative. Since the beginning of the twenty-first century, numerous Open-Source Operating Systems, databases, video editors, pdf editors, collaboration tools, password managers, and automation have been produced thanks to technical advancements and inventions.

Open source operating systems should be our first focus. The following are some of the top open-source operating systems:

1. Linux Kernel: Linus Torvalds created the Linux kernel. It provides the fundamental operations necessary for an operating system, such as data deletion, memory processing, and hardware interfacing. Because Linux is open-source software, many programmers have studied the source code and created a wide range of practical plug-ins and operating systems to suit their needs.

2. FreeBSD: FreeBSD is a prominent server platform and free Unix-like operating system with open source. Depending on your demands, FreeBSD may be used as a powerful desktop or a development computer. Additionally, it supports network services such as web, email, files, and other applications. Internet server reliability is one of the most well-known characteristics of FreeBSD. Netflix and Sony rely on FreeBSD to provide reliable PlayStation console service.

The most well-known open source databases are included in the list below.

1. MySQL: A popular relational database management system (RDBMS) called MySQL runs as a server and gives multiple users access to various databases. The daughter of co-founder Michael Widenius, My, inspired the name MySQL. The majority of MySQL's development staff, which has Swedish roots, currently works for Oracle Corporation, which bought MySQL in 2008. Over 3,500 open source developers have contributed to MySQL, which has been translated into more than 65 languages.

2. MariaDB: MariaDB is a relational database management system. MariaDB, a clone of MySQL, is designed to be free and open-source software under the GNU General Public License. Some of the original MySQL developers that branched MySQL in 2009 out of fear that MySQL would be acquired by Oracle Corporation built it. It can be used as a substitute for MySQL and is particularly well-liked by businesses that choose open-source solutions over proprietary ones. The software's main functions are very comparable to those of MySQL, and the majority of its improvements enhance performance and usability. It should also be simple for you to move between databases if necessary because it is compatible with MySQL.

3. PostgreSQL: The open source relational database management system (RDBMS) PostgreSQL places a strong emphasis on standards compliance, portability, and dependability. It was developed in 1986 at the University of California, Berkeley, by Michael Stonebraker and colleagues. Support for complex data types and SQL extensions stands out as a distinguishing feature. It is a well-liked option for companies creating enterprise software because of its wide feature set. Extensible Stylesheet Language Transformations (XSLT) are used by PostgreSQL to produce XML.

The top 3 open source video editing programs for 2022 are shown below:

1. ShotCut: One of the best video editing programs that is also open-source is ShotCut. Because it is built on FFmpeg, it can support a wide variety of file formats.

ShotCut runs on Microsoft Windows, Mac OS, and Linux. ShotCut is a straightforward-looking but effective open source video editing program. ShotCut offers features like a non-linear timeline for video editing, cross-platform compatibility, a clean, simple user interface, support for a wide range of video file types, and a good library of video and sound effects.

2. Blender: For those who enjoy making and editing 3D videos, Blender is the best option. Due to its primary benefit, it is also well-liked by those who create animated films. Additionally, it is an adaptable video editing program, allowing for customization. However, there aren't many traditional video editing capabilities available in the program's default configuration. It's best for animators, 3D motion graphic designers, and producers of 3D videos. Blender is compatible with Linux, Mac OS, and Microsoft Windows. A few of Blender's capabilities include extensive 3D options including sculpting and modeling, thorough technical support, suitability for seasoned users, support for a variety of file types, 32 slots for inserting video or audio tracks, and video hardware tools.

3. LightWorks: Through an open-source application, LightWorks is synonymous with high-quality video production and editing. That is why some of the most well-known Hollywood films' videos were edited using LightWorks software. It provides an intuitive editing interface, and people highly praise its effective technical help. LightWorks runs on Microsoft Windows, Mac OS, and Linux. LightWorks is open-source video editing software of the highest caliber, and even the free edition has a ton of fantastic editing features. LightWorks provides a variety of video file types, enables Multicam video editing, includes royalty-free video and audio samples, and has presets for 2D and 3D text animation.

Selenium is a fantastic automated testing solution for web apps since it works with a wide range of programming languages, testing frameworks, browsers, and OS systems. It enables you to write very efficient test scripts for exploratory testing, regression testing, and quickly reproducing bugs.

Is Java Open Source?

Yes. Java is open source, with a global community dedicated to directing its continued development and expansion. Java's use cases may have shifted over time, but its purpose and mantra have remained consistent: write once, run anywhere. Java, on the other hand, was developed and supported by Sun Microsystems and is now supported by Oracle.

Because Java traveled a tortuous route to its open source destination in the early stages, developers and other users have been naturally perplexed about whether Java is open source. However, the open source status of Java can be stated as follows: Java began its open source journey in 2006, but it was finished with a full reference implementation in 2011 with the release of Oracle's Java SE 7. Oracle leads the OpenJDK community in open-source Java development. The Java Community Process(JCP) manages the specification procedures.

Is Android Open Source?

Yes. Android is an open source mobile operating system and a corresponding open source project led by Google. Android is built on the Linux kernel, and like that sophisticated piece of code, the majority of its components are open-source, with the exception of a few binary blobs that are included to make things work with specific hardware. Anyone can do whatever they want with the core Android platform, known as the Android Open Source Project (AOSP). The Android Open Source Project (AOSP) repository contains the information and source code required to develop custom variants of the Android operating system, port devices, and accessories to the Android platform, and ensure devices meet the compatibility requirements that keep the Android ecosystem healthy and stable for millions of users.

Android's purpose as an open source project is to avoid any central point of failure in which one industry player can limit or influence the innovations of any other participant. For that purpose, Android is a complete, production-quality operating system for consumer products, complete with customizable source code that can be ported to practically any device and publicly available documentation.

Is Open Source Software Safe?

Yes. Open-source software is typically safe. Applications or desktop programs created by a group of volunteers are secure and cost nothing to use. Collaboratively developed projects benefit from the expertise of numerous experienced programmers and testers.

Open source projects are frequently thought to have fewer vulnerabilities by many consumers and developers. There is a claim that fewer defects exist since so many people are reviewing the open source code. When a security flaw is discovered and recorded, it can be rectified faster than with private software.

However, downloading open-source software from reputable projects is secure. To create high-quality applications, a global community of designers, developers, and testing engineers offers their skills. Patches for bugs, weaknesses, and improvements are frequently released faster than for comparable commercial products.

In open-source software, flaws are difficult to conceal. Many people are keeping an eye on well-known, established projects, so any issues are reported and rapidly fixed. You may get the most secure versions of open-source software by downloading it from the F-Droid app store, GitHub, or other reliable sites. This is because the danger is increased by the availability of the source code and the frequent use of additional open-source components. Cyber attacks are more likely to happen on smaller projects. These programs have fewer developers and slower patch release cycles.

Big open-source projects' community members conduct code reviews before integrating a contributor's work to make sure it complies with security standards. The resources to do security testing and appropriate code reviews are available in a big open source project.

Smaller projects may unintentionally accept harmful contributions or use insecure libraries because they lack such resources. In huge projects, maintainers frequently aren't as devoted to the community as the case of Event-Stream serves as an example of how crucial a robust community is to the security of a project.

What is an Open Source Software License?

An explicit license (such as the Apache Contributor License Agreement) or an implicit license may apply when an author contributes code to an open-source project (such as Apache.org). Some open-source initiatives require joint assignment of the author's copyright in order to accept code contributions rather than accepting donated code under a license.

The proliferation of open-source licenses is a drawback of the movement since it is frequently challenging to comprehend the legal ramifications of the various license variations. The difficulty of managing open-source use within "closed-source" commercial organizations has significantly increased with the availability of more than 180,000 open-source projects and more than 1,400 unique licenses. Some are self-developed, while others are based on popular FOSS licenses such as the GNU General Public License(GPL), Apache, or the MIT-style (Massachusetts Institute of Technology). Due to this, open-source developers are beginning to utilize classification techniques that aggregate FOSS licenses (typically based on the existence and obligations imposed by the copyleft provision; the strength of the copyleft provision).

When the US federal appeals court concluded in 2008 that free software licenses absolutely do establish legally binding limits on the use of copyrighted work and are therefore enforceable under existing copyright law, it was a significant legal victory for the open source and free software movements. As a result, if end users disregard the terms of the agreement, their license will expire and they will be guilty of copyright infringement. Despite this licensing risk, the majority of commercial software suppliers use open-source software in their products while adhering to the rules of their licenses, for example by utilizing the Apache license.

In conclusion, an open source software license is free, and anyone is free to redistribute the software without any restrictions. The source code must be made available so that the recipient can improve or alter it. The license may stipulate that enhanced versions of the program bear a different name or version number than the original product. The software could be ported to a different operating system.

In recent years, numerous famous and extensively used open source software licensing agreements have adopted the definition of open source. Most common Open Source Software licenses are listed below:

• The Apache web server license

• The Berkeley Software Distribution license

• The GNU General Public License

• The Massachusetts Institute of Technology License

• The Mozilla Public License

• The GNU Lesser General Public License

• The Eclipse Public License

What are the Open Source Software License Types?

Copyleft licenses and permissive licenses are two types of open source licenses. Although there are more than 200 open source licenses available, they all typically fall into one of two groups. Permissive and copyleft are those. By 2020, 14% of open source software will be based on copyleft licenses and 76% will be permissive.

• Permissive License: With permissive licenses, you can freely reproduce, alter, mix, and redistribute the work. Permissive licenses will be the foundation of about 76% of open source software by 2020. When redistributing software with a permissive license, users are typically simply obliged to include "the original copyright notice" and "a copy of the license text". The Apache, MIT, and BSD licenses are the three most widely used permissive open-source licenses.

• Copyleft License: You are also granted the same rights under copyleft and permissive licenses. However, you must make the entire work available under a copyleft license. To put it another way, if you release a software library under a copyleft license (like the GPL), someone else would not be permitted to use it with a proprietary library. The complete program must be developed under the GPL license.
