Modular visual interface for GDB in Python.

This comes as a standalone single-file .gdbinit which, among the other things, enables a configurable dashboard showing the most relevant information during the program execution. Its main goal is to reduce the number of GDB commands issued to inspect the current program status allowing the programmer to focus on the control flow instead.

In order to measure the doppler effect for motion detection on a conventional computer, what you can do is send out a sinusoid at some known (inaudible) frequency, say, 20 kHz. If something is moving in the room, then, after the sinusoid has bounced around on the walls and into the microphone, the sound will shift in frequency. This can be measured by looking at the frequency spectrum in the nearby region of the 20 kHz tone.

This document looks at the numerous and interesting ways the Linux kernel 2.6 interacts with user space programs. We explain sockets, procfs (and similar virtual filesystems), creating new Linux system calls, as well as mundane file and memory handling.
