1. In this chapter we use "open source" and "free" as synonyms, even though there are slight differences in meaning (see their glossary entries).

3. Herraiz et al. [231] fitted a quadratic polynomial to the SLOC and number of files data and looked at the coefficient of the quadratic term as an indication of the overall trend.
4. Current proprietary systems are less monolithic and there are serious (e.g. Agile) process model alternatives to the waterfall. This is likely to affect the validity of the laws even for proprietary systems.
5. Ideally one would like to compare data from both recent proprietary and recent OSS. However, access to data on proprietary systems is restricted.
