开源软件项目中的胖尾、长记忆、成熟和老化
Fat tails, long memory, maturity and ageing in open-source software projects
摘要：
我们报告了几个开源软件项目的活动数据分析，重点关注修改之间的时间和一次修改的文件数量。两者都有厚尾分布，长期记忆，并显示系统的非平凡的互相关，表明平静期之后级联修改。此外，软件项目的成熟度可以通过修改间时间分布的指数来衡量。最后，单个文件的动态显示老化，修改的平均速率作为时间的函数遵循幂律衰减。
英文摘要：
We report activity data analysis on several open source software projects, focusing on time between modifications and on the number of files modified at once. Both have fat-tailed distributions, long-term memory, and display systematic non-trivial cross-correlations, suggesting that quiet periods are followed by cascading modifications. In addition the maturity of a software project can be measured from the exponent of the distribution of inter-modification time. Finally, the dynamics of a single file displays ageing, the average rate of modifications decaying as a function of time following a power-law.
