Kernel code quality
Interesting artcle about the quality of the kernel source code. Diomidis Spinelli compared the FreeBSD, GNU/Linux, Solaris, and Windows kernels for his article A Tale of Four Kernels:
Despite various claims regarding the efficacy of particular open or close-source development methods, we can see from the table that there is no clear winner (or loser). The two systems with a commercial pedigree (Solaris and WRK) have slightly more positive than negative marks. However, WRK also has the largest number of negative marks, while Solaris has the second lowest number of positive marks. Therefore, the most we can read from the overall balance of marks is that open source development approaches do not produce software of markedly higher quality than proprietary software development.
An interesting read.
