A good looking terminal emulator which mimics the old cathode display...

Mbox is a lightweight sandboxing mechanism that any user can use without special privileges in commodity operating systems.

Firejail is a SUID security sandbox program that reduces the risk of security breaches by restricting the running environment of untrusted applications using Linux namespaces. It allows a process and all its descendants to have their own private view of the globally shared kernel resources, such as the network stack, process table, mount table.

Patch win86/64 PE and linux86/64 binaries with shellcode

This tool can be described as a Tiny Dirty Linux Only C command that looks for coreutils basic commands (cp, mv, dd, tar, gzip/gunzip, cat, ...) currently running on your system and displays the percentage of copied data.

The runtime symbol bindings can be displayed by setting LD_DEBUG=bindings:

the search paths of each symbol lookup can be displayed by setting LD_DEBUG=symbols. If this is combined with a bindings request, you can obtain a complete picture of the symbol relocation process.

Dynamically linked shared libraries are an important aspect of GNU/Linux®. They allow executables to dynamically access external functionality at run time and thereby reduce their overall memory footprint (by bringing functionality in when it's needed). This article investigates the process of creating and using dynamic libraries, provides details on the various tools for exploring them, and explores how these libraries work under the hood.

This article explores some of the Linux architectures that support real-time characteristics and discusses what it really means to be a real-time architecture. Several solutions endow Linux with real-time capabilities, and in this article I examine the thin-kernel (or micro-kernel) approach, the nano-kernel approach, and the resource-kernel approach. Finally, I describe the real-time capabilities in the standard 2.6 kernel and show you how to enable and use them.

There are a couple groups of settings below. The first couple go in /etc/sysctl.conf or /etc/sysctl.d/filename.conf.

What is pretty is NetworkManager 0.9.10; it’s like the lightning-quick racing yacht that Larry Ellison doesn’t have and really, really wants, but which somehow also adds a Triple-E-Class-worth of new features just for you.

The course was aimed at C developers who wanted an introduction to both general UNIX-style user-space and Linux kernel development with a focus on embedded systems issues. The course is aimed at two 8-hour days, and is pretty packed in even then.
