Conferences, conventions, and symposiums focused on free and/or open-source issues and technologies are the focus of topics in this category.
With source codes open to public scrutiny and modification, there is more public participation in free and/or open-source software than in proprietary alternatives. Programmers, interested in enhancing their own coding skills, often rely on open-source software. Due to the fact that the code can be viewed and modified, programmers can base their projects on existing software, modifying it make it better, or to serve a new purpose, then publishing it as their own.
Businesses, organizations, and governmental bodies sometimes turn to open-source software, not only for cost efficiency, but because it can be customized to meet specific needs, and upgraded as needed, improving the value of the software to the company with each build. Too often, with proprietary software, a business has to adapt to the available software. With open-source applications, they can adapt the software to their own needs.
For these reasons, the future of free software and open-source alternatives to proprietary software looks bright. With large numbers of programmers, information technology professionals, businesses, and others having an interest in open-source software, there are several scheduled meetings, many of them on a large scale, every year.
Sponsored by various open-source and free software organizations, universities, and technology companies, many of these events cover the full range of free and open-source technology, while others are focused on a particular software, project, or industry.
A common theme is the Linux operating system. That should be no surprise because Linux was the largest and the first open-source project.
Open-source actually began with the SHARE Operating System (SOS) in the late 1950s, but Linux family of open-source operating systems is credited with carrying the open-source banner further than any other project. Originally developed for PCs, Linux has been ported to more platforms than any other operating system, powering more Internet servers than any other OS, although it is used on less than three percent of desktop computers.
Because of its importance to the open-source community, Linux is the primary topic of several open-source conventions held throughout the world, although most of these include tracks and workshops for other open source and free software projects.
Each year, computer and technology professionals, editors and writers of technology publications, programmers, and other interested people attend conferences and events hosted around the world on topics related to this movement. Many of those with "Linux" in their names are actually general-purpose free software events, carrying the Linux name because they began as Linux-only events before widening their focus.
Regional, national, and international conferences, conventions, and other events whose topics are focused on free and open-source software are appropriate for this category.
