2. OPEN SOURCE SOFTWARE WHAT IS OPEN SOURCEHISTORY OF OSSWHAT IS SOURCE CODETotal no of slides: 16USE OF OSSFREE AND OPEN SOURCE SOFTWAREREFERENCES: WHAT IS FREE AND OPEN SOURCE SOFTWAREGNU PROJECTwww.gnu.orgSTRENGTH www.askubuntu.comWHY LINUX IS BETTERwww.wikipedia.comwww.youtube.com 3. What is? Open Source?? 4. Open Source Software is distributed withitssource code 5. 1 RUN THEFOR ANY 6. TOAND2THE 7. 3TO FREELY COPIES 8. 1970: UNIX operating system developed at Bell Labs and by adiverse group of contributors outside of Bell Labs.1983: Richard Stallman founds the Free Software Foundation1993: Linus Torvalds releases first version of Linux built1997: Debian Free Software Guidelines released 9. HIGH LEVEL Translate in Assembly language Lower level to a lower level to machine language Language (assembly) 10. Typical OSS Development model Improvements (as source code) and Developer evaluation results: User as DeveloperDevelopment TrustedBug ReportsCommunityDeveloperTrusted Repository Distributor User 11. USE OF OPEN SOURCE SOFTWARE 12. Some Examples of OPEN SOURCE SOFTWARE Operating Systems Programming Tools Linux Zope, and PHP. Android Languages: FreeBSD, PerlOpenBSD, and PythonNetBSD: Ruby Internet Tcl/Tk Apache, GNU compilers and tools BIND GCC Sendmail Make Mozilla Autoconf OpenSSL Automake etc. 13. Free software is a matter ofliberty, not price.Free software is a matter of the usersfreedom torun, copy, distribute, study,changeand improve the software. 14. 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 toyour needs. Freedom 2: The freedom to redistribute copies so you can help your neighbor. Freedom 3: The freedom to improve the program, and release yourimprovements to the public, so that the whole community benefits. 15. The GNU ProjectThe GNU Project is a free softwareproject, announced on 27 September1983, by Richard Stallman at MIT. ("GNU" stands for "GNUs NotUNIX"). GNU system, a kernel, wasfilled by the third-party Linux Kernelbeing released as Free Software,under version 2 of the GNU GPL. 16. FOSS StrengthsAbility to fit local needsyou can modify and enhance the software to more closely fit your own needs.No restrictions on useNo restrictions on how the software is used and no invoices for each user license.Low costNo charge for the software itself. Pay only for needed support or any additionalproducts & services if required. Even then huge savings than commercial SW.User-drivenyou decide what features are important and deserve attention .ReliabilityMature open-source code is as bulletproof as software ever gets.No supplier lock-inOpen Source software allows you to access the source code for your applicationsand store your data in open standard 17. 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 18. SO ARE YOU READYAS KING?Thanking You 19. Difference between OSS and FOSSFOSSOSS Open source merely means that theFree can mean one of two things Source code is made available by1.Free as in free to be modified Developers and is not necessarily2.Free as in Cost Nothingfree to be modified and free as in cost nothing 20. 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.
