Title
Why open source software can succeed

Abstract
The paper discusses three key economic problems raised by the emergence
and diffusion of open source software: motivation, coordination, and diffusion under a dominant standard. First the movement took off through the activity of a software development community that deliberately did not follow profit motivations. Second, a hierarchical coordination emerged without the support of an organization with proprietary rights.

Third, Linux and other open source systems diffused in an evnvironment dominated by established proprietary standards, which benefited from significant increasing returns. The paper show that recent developments in the theory of critical mass in the diffusion of technologies with network externality may help to explain these phenomena.

Title:
Satisfying Heterogeneous User Needs via Innovation Toolkits: The Case of
Apache Security Software

Abstract
Manufacturers customarily provide only a few product variants to address the average needs of users in the major segments of markets they serve. When user needs are highly heterogeneous, this approach leaves many seriously dissatisfied. One solution is to enable users to modify products on their own using innovation toolkits.?We explore the effectiveness of this solution in an empirical study of Apache security software. We find high heterogeneity of need in that field, and also find that users modifying their own software to be significantly more satisfied than non- innovating users. We propose that the user toolkits solution will be useful in many markets characterized by heterogeneous
demand.d.onality on offer. We also find that users creating their own software modifications are significantly more satisfied than are non-innovating users. We conclude by suggesting that the “toolkits for user innovation” approach to enhancing user satisfaction might be generally applicable to markets characterized by heterogeneous user needs.

Title:
Motivation of Software Developers in Open Source Projects: An Internet-based Survey of Contributors to the Linux Kernel

Click to access rp-hertelniednerherrmann.pdf

Abstract:
The motives of 141 contributors to a large Open Source Software project(the Linux kernel) was explored with an internet-based questionnaire study. Measured factors were both derived from discussions within the Linux community as well as from models from social sciences. Participants’ engagement was particularly determined by their identification as a Linux developer, by pragmatic motives to improve own software, and by their tolerance of time investments. Moreover, some of the software development was accomplished by teams. Activities in these teams were particularly determined by participants?evaluation of the team goals as well as by their perceived indispensability and self-efficacy.

Guarding the Commons: How Community Managed Software Projects Protect
Their Work

Click to access rp-omahony.pdf

Abstract:
Theorists often speculate why open source and free software project contributors give their work away. Although contributors make their work publicly available, they do not forfeit their rights to it. Community managed software projects protect their work by using several legal and normative tactics, which should not be conflated with a disregard for or neglect of intellectual property rights. These tactics allow a project intellectual property to be publicly and freely available and yet, governable. Exploration of this seemingly contradictory state may provide new insight into governance models for the management of digital intellectual property.

Title
Community, Joining, and Specialization in Open Source Software
Innovation: A Case Study

Click to access rp-vonkroghspaethlakhani.pdf

Abstract:
This paper develops an inductive theory of the open source software
innovation process by focussing on the creation of Freenet, a project
aimed at developing a decentralized and anonymous peer-to- peer
electronic file sharing network. We are particularly interested in the
strategies and processes by which new people join the existing community
of software developers, and how they initially contribute code.
Analyzing data from multiple sources on the Freenet software development
process, we generate the constructs of “joining script”,
“specialization”, “contribution barriers”, and “feature gifts”, and
propose relationships among these. Implications for theory and research
are discussed.

Title
How Open is Open Enough? Melding Proprietary and Open Source Platform
Strategies

Click to access rp-west.pdf

Abstract:
Computer platforms provide an integrated architecture of hardware and
software standards as a basis for developing complementary assets. The
most successful platforms were owned by proprietary sponsors that
controlled platform evolution and appropriated associated rewards.
Responding to the Internet and open source systems, three traditional
vendors of proprietary platforms experimented with hybrid strategies
which attempted to combine the advantages of open source software while
retaining control and differentiation. Such hybrid standards strategies
reflect the competing imperatives for adoption and appropriability, and
suggest the conditions under which such strategies may be preferable to
either the purely open or purely proprietary alternatives.

Title:
Gift economies in the development of open source software:
Anthropological reflections

Click to access rp-zeitlyn.pdf

Building on Eric Raymond work this article discusses the motivation
and rewards that lead some software engineers to participate in the open
source movement. It is suggested that software engineers in the open
source movement may have sub-groupings which parallel kinship groups
such as lineages. Within such groups gift giving is not necessarily or
directly reciprocated, instead members work according to the xiom of
kinship amity??direct economic calculation is not appropriate within
the group. What Bourdieu calls ymbolic capital?can be used to
understand how people work in order to enhance the reputation (of
themselves and their group).

Title:
Re-working by the Linux Kernel developers

Click to access ratto.pdf

Abstract:
Technology design is generally a matter of re-working existing systems
rather than the designing of entirely novel artifacts. In this paper I
explore part of a computer operating system called Linux that is
designed to be re-worked by its users, a process I call ‘designing for
redesign’. I examine the practices of reworking within this development
effort using some concepts gleaned from activity theory, a
meta-theoretical model that particularly focuses on the simultaneously
material and conceptual aspects of artifacts. This work is two- fold;
first to examine design as part of a larger activity of re-working, and
second, to begin to put together a model of socio-technical activity
that incorporates the complex epistemological and ontological conditions
that characterize current human conditions. Understanding the sociality
and materiality of “knowing” and “doing” in technologized society means
unpacking what we mean when we talk of ‘access’ and understanding ‘use’
as often an activity of re-working.

Title
An Overview of the Software Engineering Process and Tools in the Mozilla
Project

Click to access reismozilla.pdf

Abstract:
The Mozilla Project is an Open Source Software project which is
dedicated to development of the Mozilla Web browser and application
framework. Possessing one of the largest and most complex communities of
developers among Open Source projects, it presents interesting
requirements for a software process and the tools to support it. Over
the past four years, process and tools have been refined to a point
where they are both stable and effective in serving the project needs.
This paper describes the software engineering aspect of a large Open
Source project. It also covers the software engineering tools used in
the Mozilla Project, since theMozilla process and tools are intimately
related. These tools include Bugzilla, a Web application designed for
bug tracking, bug triage, code review and correction; Tinderbox, an
automated build and regression testing system; Bonsai, a tool which
performs queries to the CVS code repository; and LXR, a hypertext-based
source code browser.

Title
A Framework for Open Source Projects

Click to access rotfuss.pdf

Abstract:
The historical roots of Open Source are outlined. A comparison between
Open Source projects and classical projects highlights strengths and
weaknesses of both, and defines their attributes. Existing Open Source
theories are evaluated, and the requirements for a framework for Open
Source projects are determined. The framework introduces the notions of
actors, roles, areas, processes and tools, and depicts their
interrelationships in a matrix. Each aspect of the framework is then
further developed to serve both as a conceptual foundation for Open
Source and a help for organizing and managing Open Source projects.

Title
The Economics of Free Software for a Competitive Firm

Click to access hawkins.pdf

Abstract:
This paper builds a simple economic model of the profit seeking firm
with a choice between producing an open source and proprietary
solutions. Differences between public and viral licenses are discussed
from the firm’s perpective. Advocacy issues are omitted entirely, and
the model requires no math beyond subtraction. The decision of a firm to
adopt an open source product rather than purchase is also discussed, but
is seen as a trivial and uninteresting problem.

Paypal, 網路上最大的小額付費機制，昨日(Feb.13)寄發給會員新的 user agreement(海外版). 我使用 paypal 大概有一年多的時間，因此被特赦在下次登入的六十日之內，決定是否同意新的條款。若不同意，只好吃自己的。懷疑新條款我們這些善良的人類(no robot-agent)是否能解讀：

Re-organize the information into 1) a User Agreement that sets out the basic legal relationship between you and PayPal, and 2) various Policies that set the rules for how the PayPal service works. This reorganization is intended to help you more easily understand your legal rights and obligations and to help you find answers to your questions on our various services more quickly. It also is intended to make the format of our User Agreement more consistent with that of our parent company, eBay.

Update our arbitration clause in order to clarify your dispute resolution alternatives in the event that you have a dispute that cannot be resolved through normal customer service channels.

Paypal 在去年底已由 ebay 所併購，並且與原來的付費機制(ebay payment)整合。另外，電子灣(ebay)在台灣這邊併購力傳資訊的過程相當不順利，一直到現在，雖然拍賣介面有所地域化，但仍是難以回天。這個消息對去年八月底趕來台灣的總裁 Meg Whitman 而言，絕對是第二記巴掌(第一記為 ebay 退出日本市場)。

Paypal(now an ebay’s company) 這種動不動就修改使用者同意條款的舉措，相當令人感冒。雖然我會安慰自己說『使用者的眼睛或許是雪亮的』，但不要忘記的是『行為則是被綁標的』。我還在研究 c2it, 看是否能為自己的最後尊嚴作解套。
