Game Culture and Technology• Games as immersive, experiential literary

form -- game play as emergent narrative• Gaming as rapidly growing global industry• “Modding” and making games as practice-

based learning and career development• Games as new media and cultural form• Game culture as social movement

What is free/open source software development?

• Free (as in “freedom”) vs. open source– Freedom to access, browse/view, study, modify and

redistribute the source code– Free is always open, but open is not always free

• F/OSSD is not “software engineering”– Different: F/OSSD can be faster, better, and cheaper

than SE in some circumstances• F/OSSD involves more software development tools, Web

resources, and personal computing resources

Page 16: 1 Open Source Software, Computer Games, and other Socio-Technical Processes Walt Scacchi Institute for Software Research and University of California Irvine.

OSS Development Models

• Free Software (GPL)• Open Source (BSD/MIT, Mozilla, Apache)• Corporate Source (Hewlett-Packard)• Consortium/Alliance (OSDL, SugarCRM)• Corporate-Sponsored (IBM-Eclipse, Sun-

Netbeans, Sun-OpenOffice, HP-Gelato)• Shared Source (Microsoft)• Community Source (Sakai, Westwood)

OSSD Project Characteristics• OSS Developers are always users of what they build,

while OSS users (>1%) are also OSS developers• Requires “critical mass” of contributors and OSS

components connected through socio-technical interaction networks

• OSSD projects emerge/evolve via bricolage– Unanticipated architectural (de)compositions– Multi-project component integrations

• OSSD teams use 10-50 OSSD tools to support their development work

Page 18: 1 Open Source Software, Computer Games, and other Socio-Technical Processes Walt Scacchi Institute for Software Research and University of California Irvine.

18

OSSD Project Characteristics• Operational code early and often--actively improved and

continuously adapted• Post-facto software system requirements and design

– OSSD is not Software Engineering– OSSD has its own “-ilities” which differ from those for SE

• Caution: the vast majority of OSSD projects fail to grow or to produce a beta release.

F/OSS Processes for Requirements or Design

• F/OSS Requirements/Designs – not explicit– not formal

• F/OSS Requirements/Designs are embedded within “informalisms”– Example OSS informalisms to follow (as

screenshot displays)

• F/OSS Requirements/Design processes are different from their SE counterparts.

Evolutionary redevelopment, reinvention, and redistribution

• One recurring evolutionary dynamic of F/OSSD is reinvention– Reinvention enables continuous improvement

• F/OSS evolve through continuously emerging mutations (incremental innovation/adaptation)– Expressed, recombined, redistributed via

incremental releases

23

Evolutionary redevelopment, reinvention, and redistribution

• F/OSS systems co-evolve with their development community– Success of one depends on the success of the other

• Closed legacy systems may be revitalized via opening and redistribution of their source– When enthusiastic user-developers want their cultural

experience with such systems to be maintained.

Page 24: 1 Open Source Software, Computer Games, and other Socio-Technical Processes Walt Scacchi Institute for Software Research and University of California Irvine.

24

Project management and career development

• F/OSSD projects self-organize as a meritocractic role-hierarchy and virtual project management– Meritocracies embrace incremental innovations over

radical innovations– VPM requires people to act in leadership roles based

on skill, availability, and belief in project community

• F/OSS developers want to learn about new stuff (tools, techniques, skills, etc.), have fun building software, exercise their technical skill, try out new kinds of systems to develop, and/or interconnect multiple F/OSSD projects (freedom of choice and expression).

Making games as career development

Socio-technical and cultural evolution processes

• New processes under study– Joining and contributing to a project in progress– Role-task migration: from project periphery to center– Alliance formation and community development

• Independent and autonomous project communities can interlink via social networks that manipulate objects of interaction– Enables possible exponential growth of interacting and

interdependent community as socio-technical interaction network

Informal Science Education

• Science Games

• (Mechanical) Systems Engineering Game

• Dinosaur and Life Science Game– Physical game linked to online/virtual game– Venue for action research

• Games for Libraries

T.Rex

• Game story task 1 (grades 1-2)– How does a T.Rex stand and run with short arms

(front legs) and a long tail?– How might the tail help the dinosaur when eating?

• Domain requirement: must address national/CA science education standards

• Example learning task: Place and (re)size tail and neck vertebra into “see-saw” balance system

Computer Games in Libraries

• Libraries as community centers for games culture and technology

• New game opportunities for public libraries– Science learning games– Game-based graphic novels– Game modding– Library-specific games

Page 46: 1 Open Source Software, Computer Games, and other Socio-Technical Processes Walt Scacchi Institute for Software Research and University of California Irvine.

46

Library-Specific Games

• Knowledge Quest – navigational, adventure/discovery game– find and assemble knowledge from library

resources– acquire practice and skill of library researcher– resident librarians as game masters/mentors– “open source” game engine, content

development, and community participation
