Abstract: Software development is undergoing a major change away from a fully closed software process towards a process that incorporates open source software in products and services. Just how significant is that change? To answer this question we need to look at the overall growth of open source as well as its growth rate. In this paper, we quantitatively analyze the growth of more than 5000 active and popular open source software projects. We show that the total amount of source code as well as the total number of open source projects is growing at an exponential rate. Previous research showed linear and quadratic growth in lines of source code of individual open source projects. Our work shows that open source is expanding into new domains and applications at an exponential rate.

I’ll be moderating the experts panel on “Global Open Source Trends and Public Initiatives” at the half-day Global Open Source Conference on March 24th, 2008, in San Francisco. Panel participants are Mark Radcliffe of DLA Piper, Sander Ruiter from the Dutch Ministry of Economic Affairs, Tony Wasserman of CMU West, and Arnaud Le Hors of IBM. The event precedes the Open Source Business Conference which will start the next day.

Abstract: Commercial software firms are increasingly using and contributing to open source software. Thus, they need to understand and work with open source software development processes. This paper investigates whether the practice of continuous integration of agile software development methods has had an impact on open source software projects. Using fine-granular data from more than 5000 active open source software projects we analyze the size of code contributions over a project’s life-span. Code contribution size has stayed flat. We interpret this to mean that open source software development has not changed its code integration practices. In particular, within the limits of this study, we claim that the practice of continuous integration has not yet significantly influenced the behavior of open source software developers.

ComputerWorld Canada recently published an article about the closing keynote on open source that I had given at the Free Software & Open Source Symposium in Toronto last year. The basic tenet of the article is that I had claimed that software developers will fall on hard times due to open source. This is obviously not true, at least not in a naive sense.

Title: How to Benefit from Open Source
Presenter: Dirk Riehle
Institution: SAP Research, SAP Labs LLC
Abstract: Open source is changing the game of how software is built and how money is made. This talk analyzes the economics of open source software from three main perspectives: The system integrator perspective, the start-up firm perspective, and the individual software developer perspective. A focus is on the distinction between community open source and commercial open source, and how the different stakeholders use different approaches to win in the market, e.g. to gain market share or to keep a job. The dual-license strategy is explained as well as why committers to important open source software projects can expect a higher salary. The talk shows how every stakeholder can benefit and thereby explains why open source is here to stay.
