The document discusses a seminar on open source and free software. It defines open source software as software distributed with its source code. It provides a brief history of open source software including the development of UNIX, the founding of the Free Software Foundation, and the release of Linux. It also discusses the key freedoms of free and open source software including the freedom to use, modify, and distribute the software. Examples of widely used open source software are also provided.
Open Source Software and Free Software
- 1. A SEMINAR ON OPEN SOURCE SOFTWARE and FREE SOFTWARE By Dhurjati borah 5TH SEM,MCA / 9TH OCT 2012
- 2. OPEN SOURCE SOFTWARE WHAT IS OPEN SOURCE HISTORY OF OSS WHAT IS SOURCE CODE Total no of slides: 16 USE OF OSS FREE AND OPEN SOURCE SOFTWARE REFERENCES: WHAT IS FREE AND OPEN SOURCE SOFTWARE GNU PROJECT www.gnu.org STRENGTH www.askubuntu.com WHY LINUX IS BETTER www.wikipedia.com www.youtube.com
- 4. What is ? Open Source??
- 5. Open Source Software is distributed with its “source code”
- 6. 1 RUN THE FOR ANY
- 7. TO AND 2 THE
- 8. 3 TO FREELY COPIES
- 9. 1970: UNIX operating system developed at Bell Labs and by a diverse group of contributors outside of Bell Labs. 1983: Richard Stallman founds the Free Software Foundation 1993: Linus Torvalds releases first version of Linux built 1997: Debian Free Software Guidelines released
- 10. HIGH LEVEL Translate in Assembly language Lower level to a lower level to machine language Language (assembly)
- 11. Typical OSS Development model Improvements (as source code) and Developer evaluation results: User as Developer Development Trusted Bug Reports Community Developer Trusted Repository Distributor User
- 12. USE OF OPEN SOURCE SOFTWARE
- 13. Some Examples of OPEN SOURCE SOFTWARE Operating Systems • Programming Tools – Linux – Zope, and PHP. – Android – Languages: – FreeBSD, • Perl OpenBSD, and • Python NetBSD: • Ruby • Internet • Tcl/Tk – Apache, – GNU compilers and tools – BIND • GCC – Sendmail • Make – Mozilla • Autoconf – OpenSSL • Automake • etc.
- 15. “Free software” is a matter of liberty, not price. Free software is a matter of the users’ freedom to run, copy, distribute, study,change and improve the software.
- 16. FOSS refers to four kinds of freedom : • Freedom 0: The freedom to run the program, for any purpose. • Freedom 1: The freedom to study how the program works, and adapt it to your needs. • Freedom 2: The freedom to redistribute copies so you can help your neighbor. • Freedom 3: The freedom to improve the program, and release your improvements to the public, so that the whole community benefits.
- 17. The GNU Project The GNU Project is a free software project, announced on 27 September 1983, by Richard Stallman at MIT. ("GNU" stands for "GNU's Not UNIX"). GNU system, a kernel, was filled by the third-party Linux Kernel being released as Free Software, under version 2 of the GNU GPL.
- 18. FOSS Strengths Ability to fit local needs you can modify and enhance the software to more closely fit your own needs. No restrictions on use No restrictions on how the software is used and no invoices for each user license. Low cost No charge for the software itself. Pay only for needed support or any additional products & services if required. Even then huge savings than commercial SW. User-driven you decide what features are important and deserve attention . Reliability Mature open-source code is as bulletproof as software ever gets. No supplier lock-in Open Source software allows you to access the source code for your applications and store your data in open standard
- 19. Why Linux is Better ?? 1.Forget about viruses. 2.Do not pay for Operating System. 3.Forget about Drivers. 4.Update all of your software with a single click. 5.Your system is stable. 6.Linux protects your computer
- 20. SO ARE YOU READY AS KING? Thanking You
- 21. Difference between OSS and FOSS FOSS OSS Open source merely means that the Free can mean one of two things… Source code is made available by 1.Free as in “free to be modified” Developers and is not necessarily 2.Free as in “Cost Nothing” “free to be modified” and “free as in cost nothing”
- 22. USE OF OPEN SOURCE SOFTWARE • 8,50,000 – Android phones running in Linux and 30,000 windows phone. • 9 out of 10 of the Super Computer run in Linux. • Google, twitter,facebook,amazon.com powered by Linux • Since 2005, 8000 developers from 800 companies • 15 milions lines of code. • A new kernel comes out every 2-3 months.
