- many disparate development platforms
- a myriad places where distribution may happen
- projects tend to migrate from one place to another over time

*** Like all digital information, FOSS is fragile
- inconsiderate and/or malicious code loss (e.g., Code Spaces)
- business-driven code loss (e.g., Gitorious, Google Code)
- for obsolete code: physical media decay (data rot)

*** A wealth of software research on crucial issues...
- safety, security, test, verification, proof
- software engineering, software evolution
- empirical and big data studies
