One of the interesting things about writing code in high level garbagecollected languages is how your optimization concerns can change. Oneoptimization in all GC'd languages, Python included, is minimizing thecreation of new objects and maximizing the reuse of old ones; thefewer new objects you create, the fewer cycles garbage collectioneats, the less memory gets fragmented, and you often even use lessmemory overall.

Minimizing object churn is behind several well-known Python(anti-)patterns, such as 'avoid repeated string

Modifying a Linux kernel configuration option can be an annoyingexperience, as you poke around the menus of ' make menuconfig ' tryingto find where the configuration option you want to change is hiding.Fortunately there's a less well known but much easier way.

The kernel build process stores configuration settings in the file .config in the root of the kernel source tree. However, it generatesother things from the file (and some options are interdependent), so youcan't just edit the file and go;
