Evolution of the core team of developers in libre software projects

Gregorio Robles, Jesus M. Gonzalez-Barahona, Israel Herraiz
2009 2009 6th IEEE International Working Conference on Mining Software Repositories  
In many libre (free, open source) software projects, most of the development is performed by a relatively small number of persons, the "core team".  ...  The stability and permanence of this group of most active developers is of great importance for the evolution and sustainability of the project.  ...  This work has been funded in part by the European Commission, through projects FLOSSMetrics, FP6-IST-5-033982, QUALOSS, FP6-IST-5-033547, and Qualipso, FP6-IST-034763, and by the Spanish CICyT, project  ...

Impact of the Creation of the Mozilla Foundation in the Activity of Developers

Jesus M. Gonzalez-Barahona, Gregorio Robles, Israel Herraiz
2007 Fourth International Workshop on Mining Software Repositories (MSR'07:ICSE Workshops 2007)  
To answer these questions, we have performed an analysis of the CVS repository of Mozilla, using the CVSAnalY tool, finding little on activity, but dramatic changes in the the composition of the development  ...  team.  ...  Generations analysis At any given moment in the life of a libre software project, the level of activity of each of the members of the development team can be very different.  ...

Open Source software engineering –- The state of research

Stefan Koch, Jesus M. Gonzalez-Barahona
2005 First Monday  
How can we estimate the effort actually spent in an open source project, and how can we measure the impact of the community surrounding the core development team?  ...  His research interests include quantitative analysis of software projects, libre software development models and implications of the use and production of libre software.

Adapting the "staged model for software evolution" to free/libre/open source software

Andrea Capiluppi, Jesús M. González-Barahona, Israel Herraiz, Gregorio Robles
2007 Ninth international workshop on Principles of software evolution in conjunction with the 6th ESEC/FSE joint meeting - IWPSE '07  
This paper focuses on the commonalities and differences between the evolution and patterns in the lifecycles of traditional commercial systems and free/libre/open source software (FLOSS) systems.  ...  The two perspectives are related in various ways: the study of the what/why is for instance essential to achieve an appropriate management of software engineering activities, and to guide innovation in  ...  Generations projects exhibit a renewal in the core group of developers; the group of people that were the main developers at a early moment in the lifetime are not the main developers in posterior moments  ...

Effort estimation by characterizing developer activity

Juan Jose Amor, Gregorio Robles, Jesus M. Gonzalez-Barahona
2006 Proceedings of the 2006 international workshop on Economics driven software engineering research - EDSER '06  
For instance, many teams are performing quantitative analysis on the large quantity of data which is publicly available from the development repositories maintained by libre software projects.  ...  However, not much of this research is focused on cost or effort estimations, despite its importance (for instance, for companies developing libre software or collaborating with libre software projects)  ...  In other words, in libre software projects the evolution of software depends a lot on the evolution of the developer population. itory, being CVS the most popular.  ...

Lessons from Volunteering and Free/Libre Open Source Software Development for the Future of Work [chapter]

Kevin Crowston
2011 IFIP Advances in Information and Communication Technology  
We then use the example of free/libre open source software (FLOSS) development teams to examine how those features and problems apply in this situation and how they might be affected by the use of information  ...  In this paper, we review research on voluntary organizations to identify key features of and problems in volunteer work and organizations.  ...  At the center of the onion are the core developers, who contribute most of the code and oversee the design and evolution of the project.  ...

Using Software Archaeology to Measure Knowledge Loss in Software Projects Due to Developer Turnover

Daniel Izquierdo-Cortazar, Gregorio Robles, Felipe Ortega, Jesús M. González-Barahona
2009 2009 42nd Hawaii International Conference on System Sciences  
Besides, we study how orphaned code is managed by the project. Our methodology is based on the concept of software archaeology, a derivation of software evolution.  ...  For a given software project, we measure the quantity of code that has been authored by developers that do not belong to the current development team, which we define as orphaned code.  ...  In such scenarios, the development team in charge of the software may suffer from turnover: old developers leave while new developers join the project.  ...
