HFOSS - paper presenters

The following paper presentations are happening with slide presentation and I believe that they take less than 15 minutes.

Position statements are next after these presentations.

NOTE: Slides are not available or linked from the website
NOTE 2: Excuse me if some notes are not easily understood



Some of the comments during the presentations worth highlighting were:
  • Best teams have been the ones that CS students have been mixed with students from other disciplines
  • Some people highlighted that what Linda has been doing makes it easier to help NPOs with open source tools since they are most graphical rather than command line oriented
  • Students do not learn to read code before writing it
  • Lack of tool knowledge by students

Notes from the presentations:

Timothy A. Budd (Oregon State University)

"A Course in Open Source Development"

  • Paterson's editorial - Open Source course would be the course I would love to take
  • We teach writing before reading code - wrong way
  • Important about Open Source:
    • Code
    • Community
    • Tools and self-development
  • Process is not well articulated - No text books in this
  • Professor teach what they have been taught. Who has experience in FOSS
  • Open source merit badges
  • First assignment - what is your passion? do some introspection
  • Next assignment - contribute something of wikipedia
  • Make the students present
  • Outside speakers
  • A paper or patch every two weeks
    • it doesn't have to be accepted
    • peer reviewed by students
  • It is all about the process, not the product

Gary Thompson (San Francisco State University, Sun Microsystems)

  • this is a course in distributed development
  • Global Software Engineering
  • a student's project example -
  • every day he sees the need of developers that have the open source methodologies
  • dstributed collaborative class among few universities
  • this is a process oriented class, not a technology oriented class
    • globalization
    • outsourcing
    • and others
  • students learn by doing things
  • break students into teams and assign project
  • they have to go through the whole software development cycle
  • we treat the team as start ups
  • we provide all the teams the needed tools
  • software development tools
    • netbeans, java EE, linux, open Solaris
  • collaborative tools
    • archive mailing lists, version control, skype, IM
  • require the completion of 6 milestones
  • description of milestone 0
    • first 2 weeks of class
    • they have to setup the environments
    • students normally don't estimate properly how much work it takes to setup the tools
    • this milestone helps them deal with that immediately
  • CCLI Grant Proposal to National Science Foundation
  • he presents some publications on their last slide

Yunrim Park (Oregon State University)

"Supporting the Learning Process of Open Source Novices: An Evaluation of Visualization Tools"

  • this presentation talks about that visualization tools helps the learning process of the source code. It also explains the experiment
  • overwhelming
  • feeling that you have to know the whole project before you can submit patches
  • dealing with a large code base
  • learning about the community
  • interaction with existing members of the community (intimidation)
  • finding entry points (hard)
  • lowering barriers: visualization
    • lower the "cost" of joining OSS projects?
  • they did an experiment to see if visualization tools help them
  • group A
    • access to open source sourceforge website, wiki, tracking system
  • group B
    • two eclipse plug-ins
  • group C
    • two standalone tools
  • Change history (Augur)
    • you can see in different colors the authors of the modifications
  • Code Structure (Creole)
    • you can see a diagram on how the source code is connected
  • completeness vs correctness
  • in SUMMARY:
    • information visualization helps
      • Creole and Version tree both provided insights into overall code organization and structure
      • Source Forge was really intimidating
    • Females showed low self-efficacy in activities that involve close interaction with other members

Cay Horstmann (San Jose State University)

"Challenges and Opportunities in an Open Source Software Development Course"

  • The OSS Class at SJSU
  • the focus on gaining an understanding of the open source methodologies, business aspects
  • students are not very tools savy
    • version control
    • build automation
    • patching
    • test automation
    • cross-platform development
  • we have to spend a lot of time in teaching tools
  • tools are not the only problem
  • they lack the human skills
    • reading before asking
    • asking good question
    • putting yourself into their shoes
    • effective participation in discussions
    • submitting good patches
  • business and legal background
    • licenses
    • paid vs voluntary contributions
    • motivation
    • organizational structure
    • open standards
    • patents and copyrights
  • challenges
    • vast difference in student skills
    • many students lacking tool knowledge, cross-platform skills
    • limited experience with OSS products (often only Firefox, Eclipse)
    • social skills: asking questions, understands other perspectives
    • surprise: the facebook generation is shy about being out in the open
    • surprise: bad coders also most lacking in business skills
  • benefits
    • successfully working with large code base greatly increases confidence
    • students were motivated to do better when seeing marginal coding practices
    • tools become second nature
    • students gain respect for platform and configuration issues
    • first exposure to legal, business, professional issues for many students
  • conclusions
    • course stresses skills that are valued by employers
    • have realistic expectations
    • push for curricular improvements
      • tools taught earlier
      • learn how to read code, not just write it

Linda Seiter (John Carroll University)

"Computer Science and service learning: Empowering nonprofit organizations through open source content management systems"

  • capstone course
  • traditional issue - sustainability of that project
  • NPOs are the least capable to maintain projects
  • John Caroll University - Center for Service and Social Action
    • 2007 - 1300+ volunteers (~3000 undergrads)
    • 70+ nonprofit community partners
    • no computer students unfortunately got involved
    • business school case studies
      • have web presence
      • charity events
      • lack of technical staff
  • NOSI - Nonprofit Open Source initiative
    • class taught at their university
    • most popular FOSS software
      • CMS
      • CRMS
  • CS444 - Adaptive and open software systems
    • computer info systems learning objectives
    • free and open artifacts
    • explore business and societal impact of FOSS
    • readings, peer review
  • CS444 - Service Learning
    • build web site
    • train end users of the CMS system
    • service activities with community partner
    • contribute to open source CMS
  • She shows a web site as an example:
    • "Interfaith Hospitality Network of Greater Cleveland"
    • "Thea Bowman Center"
  • Good together: FOSS + NPOs
