Sommario/riassunto

This book contributes new insights into the organization of free/open source (F/OS) software communities by examining the links between learning, division of labour and commercialization, demonstrating the need for a synthesis of work on both community organization and cooperation to understand F/OS community dynamics. These aspects are examined in the light of detailed case studies of the GNOME and KDE projects. This book offers an innovative theoretical framework, a critical assessment of various methodologies for examining the



organisation of F/OS communities, and a typology of commercia

Sommario/riassunto

Since the 1960s, testimony by representatives of the Federal Bureau of Investigation in thousands of criminal cases has relied on evidence from Compositional Analysis of Bullet Lead (CABL), a forensic technique that compares the elemental composition of bullets found at a crime scene to the elemental composition of bullets found in a suspect (TM)s possession. Different from ballistics techniques that compare striations on the barrel of a gun to those on a recovered bullet, CABL is used when no gun is recovered or when bullets are too small or mangled to observe striations. Forensic Analysis: Weighing Bullet Lead Evidence assesses the scientific validity of CABL, finding that the FBI should use a different statistical analysis for the technique and that, given variations in bullet manufacturing processes, expert witnesses should make clear the very limited conclusions that CABL results can support. The report also recommends that the FBI take additional measures to ensure the validity of CABL results, which include improving documentation, publishing details, and improving on training and oversight.
