Much by way of discourse, some by way of advice; security from Clausewitz to Claude.
Today we'll cover how to use the dbus interprocess communication (IPC) mechanism to integrate the Clementine music player into i3status. We'll write a small script in Python that determines Clementine's state using the dbus library, and then appends that state to the i3status bar. While we're at it, we'll also learn quite a bit about dbus!
In this, part 6 of our Linux Environment series, we'll cover how to install xscreensaver, and write a script that checks for full screen windows. Then we'll connect the two to stop your machine from going to sleep in the middle of movies!
In this tutorial we'll cover how to perform a simple buffer overflow by jumping to shellcode that we've stored in an environment variable. We'll cover how to place the code, find its address, and go over a simple example of jumping to it to perform an exploit.
In this tutorial, we'll cover how to create and use command line pipelines. We'll go over a little bit of background on what they are, work through a couple of examples and finally address a common pipeline difficulty to do with standard error.
One very common command line activity is process control. In this tutorial, using tools like kill, and builtins like fg and jobs to interact with processes, and cover how to run them in both the foreground, and background of a single terminal.
