Who contributes voluntarily to OSS? An investigation among German IT employees

Based on newly assembled survey data, we analyze which individual characteristics of IT employees are associated with the willingness to participate voluntarily in Open Source Software (OSS) projects. We find that, contrary to common expectations, formal educational attainment is not positively associated with the probability or level of OSS contributions. The group of university dropouts, however, does show a particularly high probability of working on such projects. Furthermore, we obtain the striking and novel finding that work-related OSS activities play an important role in determining voluntary OSS contributions during leisure time. Although one has to be cautious regarding the direction of causality, we interpret this as evidence of career-oriented motives in voluntary OSS contributors. The finding is also reinforced by our more specific analysis of the importance of such motives in determining the actual effort invested in OSS projects.     

H.264熵编码的技术研究及H.264的应用展望

随着视频通信的发展,多媒体通信平台功能越来越强大,同时也对视频编码的性能提出了更高要求。H.264视频编码标准正因为使用了熵编码技术,使得其压缩效率大大提高,同时图像质量和差错鲁棒性方面也表现优异,成为图像处理和通信领域研究的热点问题之一。论文搭建了H.264的系统框图,对H.264的三种熵编码分别进行了技术研究,得到H.264编码的整体优势,通过其在视频通信上的应用调查,阐述H.264的前景。
