1
The good, the bad or the ugly?  Perceptions of open source
  • Scott Siddall – Denison University
  • John Bucher – Oberlin College
  • Rob Abel – IMS Global Learning Consortium



2
Roadmap
  • Brief introduction
  • Current state of open source – Rob
  • Oberlin as a case study – John
  • Denison as a case study – Scott
  • Point/Counterpoint – all
  • Open discussion


3
Why open source?
  • You can run it – share it – change it – improve it


  •   “People improve it, people adapt it, people fix bugs. And this can happen at a speed that, if one is used to the slow pace of conventional software development, seems astonishing.”


    • The Open Source Initiative http://opensource.org
4
The Expectations
  • Price – 54%
  • Flexibility - 42%
  • Functionality - 40%
  • Performance – 32%
  • TCO – 31%

5
Open source is a licensing model
  • Open Source Initiative
  • >60 licensing models
  • GPL, BSD, Mozilla, MIT are all popular
  • GNU Public License (GPL) applies to half of the 100,000+ projects at Sourceforge

7
Open Source is also a culture
  • Complex software development
  • By loosely coordinated developers and contributors
  • In an informal meritocracy
    • software specifications are rarely written
    • continuous design instead
    • virtual project management
    • a gentle hierarchy
8
“The Cathedral and the Bazaar”
  • Every good work of software starts by scratching a developer's personal itch.
  • When you lose interest in a program, your last duty to it is to hand it off to a competent successor.
  • Treating your users as co-developers is your least-hassle route to rapid code improvement and effective debugging.
  • Release early. Release often. And listen to your customers.


  • - Eric S. Raymond, 1997

Types of open source software
  • Central services and infrastructure
    • Email systems, servers, network management tools
  • Desktop operating systems
    • Linux, Sun Java Desktop
  • Web applications
    • ePortfolios, portals, course management, digital asset management, collaboration and communication tools, help desk systems, financial systems, student services
  • “Open source is moving up the stack”
  • - Brad Wheeler, Indiana University
10
The Assertions
  • Open source software costs less than proprietary software
    • Lower licensing price? – yes
    • Lower total cost?  Maybe if cost allocations are shifted
11
Many Contentions
  • OSS licensing is easy
  • OSS is more reliable, fewer bugs
  • OSS can be customized
  • Proprietary software has better interfaces
  • OSS is more secure
  • OSS is better because it uses open standards
  • OSS is by and for a community
  • Proprietary software has better support
  • OSS is difficult to install, distribute, migrate to
  • OSS avoids vendor lock-in
  • OSS reuses software elements efficiently
  • Proprietary software developers have better resources
12
Need for leadership
  •    “People think just because it is open-source, the result is going to be automatically better. Not true. You have to lead it in the right directions to succeed.”
  • - Linus Torvalds
13
Community Source
  • Purposeful coordination of work within a community
  • Based on the principles of open source development
  • A greater reliance on
    • Defined roles
    • Responsibilities
    • Funded commitments
14
Projects supported by the Mellon Foundation
  • Sakai and SAMigo
  • Westwood/Chandler
  • ePortfolio (OSP)
  • Public Key Infrastructure
  • Open Courseware
  • uPortal
  • Sophie
  • Pubcookie
  • OKI
  • Kuali
  • LionShare
  • VUE
  • Simile
15
Future of the higher ed
software market
  • We share unique software requirements
  • Education is a tiny piece of the global software market place


  • Who will create our software, at what cost?
  • Will we have to craft our own software?
  • What will be the impact of software development by for-profit education?

Case study: Denison University
  • Granville, Ohio
  • Traditional liberal arts curriculum
  • 2,150 residential students
  • Undergraduate only
  • 200 faculty members
  • 31 staff members in IT


18
Denison and Open Source
  • Key people believed in open source
  • Embrace the best solution regardless of source
  • Early adoption established a pattern in 1999
19
Denison’s choices
  • Web servers
    • Apache on Linux
  • Course management
    • Blackboard
    • CourseWork
    • Sakai
  • Content management
    • Bricolage
  • uPortal
  • Email systems

22
Email systems
  • Red Hat Enterprise Linux
  • Mail transport agent is Postfix
  • Cyrus IMAP is the mailstore
  • PHP, Perl and PostgreSQL for scripting and database
  • Horde IMP webmail
  • SpamAssassin for spam identification (along with public RBLs and filter rules)
  • Spamity to manage the spam quarantine function
  • Sympa for listserver support
  • CLAM  Anti-Virus
  • AMaViSd-new to glue the services together
23
Email systems
  • Redundant hardware
    • 11 commodity servers
    • Content switches
    • SAN
  • Provisioned for 30,000 accounts
  • Outstanding performance
  • Staff skill sets expanded
24
Discussion questions
  • What do we do with the money we save on licensing fees?
  • What’s the difference between commercial and OS software in terms of integration into campus systems?
  • Is it important that software support come from the software developer?
  • What criteria are important in assessing your campus readiness to adopt OS?
