  1. 1. An Introduction to the FreeBSD Project Dru Lavigne October 8, 2014 2014 #GHC14 2014
  2. 2. Who is Dru Lavigne? FreeBSD user since 1996 Author of O'Reilly's FreeBSD Basics column and 3 books on BSD Lead writer for PC-BSD and FreeNAS docs and doc committer for FreeBSD Project Founder and current Chair of BSD Certification Group Director at FreeBSD Foundation 2014
  3. 3. What is FreeBSD? An open source operating system descended from the Unix developed at the University of California, Berkeley An open source project since 1993 with several hundred active committers from across the globe Associated non-profit Foundation provides legal and monetary support for the Project and its committers 2014
  4. 4. What Does FreeBSD Excel At? Networking: −BSD sockets provided the original API for TCP/IP −First operating system to provide an IPv6-only networking stack −Research platform for modular TCP congestion control algorithms −High performance direct-to-hardware packet I/O (netmap) 2014
  5. 5. What Does FreeBSD Excel At? Security: −Capsicum reference platform (lightweight OS capabilities and sandbox framework) −Casper (daemon to run services in sandboxes) −Fine-tuned resource limits for processes, users, and jails −Jails provide lightweight OS virtualization since 2000 (think Docker or Solaris zones) 2014
  6. 6. What Does FreeBSD Excel At? File systems: −BSD FFS was the first file system to reduce disk fragmentation with cylinder groups −SUJ adds journaled soft updates to UFS −HAST (Highly Available STorage) provides synchronous, block-level replication over TCP/IP −OpenZFS: FreeBSD uses and actively contributes to this cross-platform, modern file system 2014
  7. 7. What Does FreeBSD Excel At? Focus on Development Tools: −Early adopters of Coverity Prevent −Early adopters of CLANG/LLVM −Built-in DTrace for system performance analysis −Heavy use of assertions and dynamic analysis (WITNESS) −Common research platform for tools, especially for security 2014
  8. 8. What Does FreeBSD Excel At? License: commercial-friendly 2-clause BSD Community: friendly and professional, many active committers/users for 10+ and 20+ yrs Mentoring: built into the Project's culture and processes Documentation: FreeBSD Handbook, FAQ, Developers' Handbook, Porter's Handbook, Documentation Project Primer, man pages 2014
  9. 9. How is FreeBSD Organized? Elected Core Team (9) helps set direction and resolve disputes Security Officer and Security Team (16) handle security advisories for supported releases Release Engineer and Primary Release Engineering Team (12) manage releases and set EOLs 2014
  10. 10. How is FreeBSD Organized? Documentation Engineering Team (5) coordinates docs/translations for releases Port Management Team (9) manages the FreeBSD Ports Collection Webmaster team (6) maintains the configuration and content of the main website 2014
  11. 11. How is FreeBSD Organized? Additional teams manage hardware donations, marketing, vendor relations, backups, cluster administration, mailing lists, the ftp/website infrastructures, etc. The Core, Ports Management, and Security teams each have a non-voting Secretary to manage minutes and incoming correspondence 2014
  12. 12. What is a FreeBSD Committer? Someone with write access to some part of the FreeBSD repositories Repositories include source code, documentation, websites, translations, and ports (third-party software) 2014
  13. 13. How to Become a FreeBSD Committer? Anyone can download FreeBSD source code and submit patches (source, ports, docs, translations) Find an area that interests you, submit patches, and engage with your patch's reviewer Engage with that portion of the community (IRC, mailing lists) In other words, get involved! 2014
  14. 14. How to Become a FreeBSD Committer? The FreeBSD community notices submitters who are easy to work with, willing to learn, and who continue to submit good patches Such submitters can be recommended for a commit bit where writes are first reviewed by at least one mentor At some point, mentor pre-approval is no longer required, though many committers still request peer review for larger patches or new functionality 2014
  15. 15. Why Become Involved? So many advantages! −Opportunity to work with a mature, open source community with well-documented processes and built-in mentoring −Ability to learn from senior-level technologists who have written file systems, networking stacks, security frameworks, etc. −Interact with people from across the globe who share your passion 2014
  16. 16. Why Become Involved? A large and diverse body of work: −Source code and documentation for all aspects of an operating system over several decades of development (think free research and learning from the people who wrote innovative stuff) −Opportunity to participate in a large source repository with several hundred active committers (think résumé and real-world work experience) 2014
  17. 17. Why Become Involved? No glass ceiling! −Noone cares about (or necessarily even knows) your age, gender, race; you are instead known by your body of work −Ability to find a niche and, over time, become an expert in that niche −Opportunity to collaborate with and build professional relationships with other experts 2014
  18. 18. Is This Too Good to be True? Not if you're smart about it: −Learn and respect the community's culture and processes −Give as much as you take and don't be afraid to pay it forward −Don't be shy, find your niche, and remember that the sky's the limit! 2014
  19. 19. Key Takeaways Any open source community provides the opportunity to learn the details of a technology, improve one's skills, network with others who share your interest in a technology, and gain real-world experience While the platform is all about the technology, the sub-text is all about community Find a community that furthers your needs and become an active contributor! 2014
