Study Outcomes
- Identify Linux's Software License -
Understand what type of software license Linux adheres to, including its key terms and conditions under the GNU General Public License.
- Analyze Copyleft Principles -
Examine the core concepts of copyleft licensing and how they ensure the freedoms to use, modify, and distribute Linux.
- Differentiate Open-Source Licenses -
Compare the GNU GPL v2 that powers Linux with other popular open-source licenses to recognize their similarities and differences.
- Recognize the FSF Founder -
Identify who formed the Free Software Foundation to promote open development and learn about their role in advocating for software freedom.
- Apply Licensing Knowledge -
Use your understanding of Linux licensing to assess compliance and best practices when contributing to or selecting open-source projects.
Cheat Sheet
- GPLv2 Foundation -
Linux adheres to the GNU General Public License version 2 (GPLv2), a copyleft license that ensures freedom to use, modify, and distribute the kernel source (kernel.org). A handy mnemonic is "Go, Participate, Liberate!" to recall the spirit of GPLv2. This license obligates derivative works to remain under the same terms, preserving community-driven development.
- Copyleft Principle -
Copyleft flips traditional copyright by requiring any distributed modifications to remain open under GPL terms, so "left" in copyleft reminds you that freedom is always handed back. According to the Free Software Foundation, this mechanism prevents proprietary forks and keeps improvements in the public domain. It's a powerful tool that aligns with Linux's collaborative ethos.
- FSF and Richard Stallman -
Richard M. Stallman formed the Free Software Foundation in 1985 to promote open development and software freedom, answering "who formed the Free Software Foundation" with a mission that still guides Linux's license choices. Remember "RMS" with "Rush My Source" to honor his push for transparency. The FSF maintains the GPL and advocates for users' four essential software freedoms.
- Open Kernel Development Model -
Linux's development on kernel.org is driven by thousands of contributors under a meritocratic hierarchy overseen by maintainers like Linus Torvalds. This structure harnesses the GPLv2's collaborative promise, encouraging peer review and rapid innovation. Keeping track of stable release trees and patch queues is a great way to witness GPL in action.
- Compliance & Community Impact -
Understanding to which license Linux adheres helps distributors follow compliance procedures - GPLv2-only means you must provide source code and disclaimers with every binary. This obligation fosters a vibrant ecosystem of distributions like Debian and Fedora that build on Linux while respecting user freedoms. Staying legally sound under GPLv2 also boosts trust and collaboration across the open-source community.
