http://aosabook.org/en/graphite.html http://aosabook.org/en/llvm.html http://aosabook.org/en/asterisk.html from the second volume.

The new volume on Performance is also very good with the http://aosabook.org/en/posa/high-performance-networking-in-c... and http://aosabook.org/en/posa/secrets-of-mobile-network-perfor...

being my favorites.
