SFLC has released a
code analysis of the infamous ath5k driver in Linux. SFLC has also - in the aftermath of the OpenBSD-Team vs. Linux-Team 'License Flame War' - released a paper on what '
copyrightable' means, as well as one on
proper usage of non-GPL'ed code in GPL'ed projects. All as part of
guidance for developers wishing to use permissive licensed code in GPL'ed projects.
Groklaw naturally also has a take on this.
