    • Open Source: It's Already Here
        • Dave Cross
        • Magnum Solutions Ltd

    • Some Facts
      • Linux is a great desktop operating system
      • Anything you can do in Windows, you can also do on Linux
    • Some More Facts
      • OpenOffice.org is as powerful as MS Office
      • Mozilla is a better browser than IE
      • Evolution does anything that Outlook does
        • (and is less vulnerable to virus attack)
    • Or Opinons
      • There are many more “facts” like these
      • But they are just personal opinions
      • They only convince Open Source fans
        • (like me)
      • So let's try another approach
    • Another Approach
      • Who has used Linux?
      • Who has used Linux today?
      • Who has used any Open Source app today?
    • Another Approach
      • Who has used PayPal today?
      • Who has used Google today?
      • Who has used Amazon today?
      • These are all Open Source applications
    • Open Source Business
      • All of these companies run their business on Open Source software
      • There are many more like them
      • What software are they using?
      • What advantages do they see?
    • Web Site Software
      • An operating system (e.g. Windows)
      • A Web Server (e.g. IIS)
      • A Database (e.g. SQL Server)
      • A Programming Language (e.g. .Net)
      • What are the Open Source equivalents for these?
    • LAMP
      • An operating system (Linux)
      • A Web Server (Apache)
      • A Database (MySQL)
      • A Programming Language (Perl, PHP and Python)
    • Linux
      • Unix Clone
      • Originally for x86 architecture
      • Now runs on many platforms
      • Well established as an alternative to Unix
      • Long heritage – GNU Project
      • Many distributions
      • Commercial support
    • Apache
      • “ A patchy server”
      • Modular architecture that makes it simple to add new features
      • The web server that all others emulate
      • Phenomenally successful
    • Apache Runs the Web Source: Netcraft (http: // www.netcraft.com)
    • MySQL
      • Small and fast database server
      • Compromises RDBMS functionality for speed
      • Alternatives
        • SQLite (even smaller, even faster)
        • PostgreSQL (slightly slower, fully featured)
      • Most commercial DBs run on Linux
        • One major exception
    • Programming
      • Perl
        • Long history of being used for the web
        • Very high level language
        • Very fast when used with Apache (mod_perl)
      • PHP
        • More like ASP
        • Code embedded in HTML
    • Programming
      • Python
        • Similar to Perl
        • More OO-based
      • Other Alternatives
        • Java (not Open Source)
        • Mono (Open Source version of .Net)
    • Open Source Advantages
      • Cost
      • Security
      • Support
      • Quality
      • Control
    • Cost
      • No license costs
      • Still pay for support and training
    • Security
      • Source code is available to everyone
      • Security becomes very important
      • “ Security by obscurity” is not an option
      • Holes get fixed quickly
    • Support
      • Most Open Source projects have very active support communities
      • Most bugs get fixed within a day
      • Fixes available immediately
    • Quality
      • Programmer pride
      • Constant peer review
      • Meritocracy
    • Control
      • You can see exactly what the program does
      • You can change what the program does
      • Documented interfaces and data formats
      • Not tied to one company's view of the world
    • Conclusions
      • Everyone uses Open Source software every day
      • Some large businesses have already chosen to move to Open Source software
      • Many of these businesses are very successful
      • There are good business reasons for using Open Source software
    • Questions
