Puppet: Mastering Infrastructure Automation
Jaime Soriano Pastor
Puppet is a configuration management tool that allows you to automate all your IT configurations, giving you control. It was written for and by system administrators to manage large numbers of systems efficiently and prevent configuration drifts. Puppet gives you control of what you do to each node, when you do it, and how you do it.This Learning Path will take you from the basics of Puppet to extending it and then mastering it. We will start off with a primer on Puppet, its installation and get a sneak peek under its hood. We will then move on to designing and deploying your Puppet architecture, learning best practices for writing reusable and maintainable code, and executing, testing, and deploying Puppet across your systems. Finally, we will deal with problems of scale and exceptions in your code, automate workflows, and support multiple developers working simultaneously.This course is based on the following books: 1)Puppet 4 Essentials - Second Edition 2)Extending Puppet - Second Edition 3)Mastering Puppet - Second Edition

Penetration testing is the use of tools and code to attack a system in order to assess its vulnerabilities to external threats. Python allows pen testers to create their own tools. Since Python is a highly valued pen-testing language, there are many native libraries and Python bindings available specifically for pen-testing tasks.Python Penetration Testing Cookbook begins by teaching you how to extract information from web pages. You will learn how to build an intrusion detection system using network sniffing techniques. Next, you will find out how to scan your networks to ensure performance and quality, and how to carry out wireless pen testing on your network to avoid cyber attacks. After that, we’ll discuss the different kinds of network attack. Next, you’ll get to grips with designing your own torrent detection program. We’ll take you through common vulnerability scenarios and then cover buffer overflow exploitation so you can detect insecure coding. Finally, you’ll master PE code injection methods to safeguard your network.

RISC-V is reshaping processor innovation with its open and extensible instruction set architecture. But how are high-performance RISC-V digital signal processors (DSPs) designed in practice? This book explores that question through SpringCore, a RISC-V DSP architecture developed for real-time embedded control systems.Using SpringCore as a case study, the book introduces the architecture of a modern DSP processor and explains key digital design techniques used in its implementation. You will explore DSP architecture concepts, design custom ISA extensions for fixed-point and floating-point acceleration, and examine an 8-stage pipelined processor with hazard handling, zero-overhead loops, a Harvard memory architecture, protection mechanisms, and interrupt handling. The book also covers the surrounding software ecosystem, including an LLVM-based toolchain, debugging with OpenOCD and JTAG, development with an Eclipse-based IDE, and simulation support using tools such as gem5. Finally, it demonstrates how the SpringCore architecture is implemented in the FDM320RV335 DSP chip, which runs at 150 MHz and integrates peripherals such as an ADC and PWM for real-time industrial control.By the end, you will understand key DSP hardware architecture and custom ISA design principles through the practical example of SpringCore.
ROS Robotics By Example. Bring life to your robot using ROS robotic applications
Carol Fairchild, Dr. Thomas L. Harman
The visionaries who created ROS developed a framework for robotics centered on the commonality of robotic systems and exploited this commonality in ROS to expedite the development of future robotic systems. From the fundamental concepts to advanced practical experience, this book will provide you with an incremental knowledge of the ROS framework, the backbone of the robotics evolution. ROS standardizes many layers of robotics functionality from low-level device drivers to process control to message passing to software package management. This book provides step-by-step examples of mobile, armed, and flying robots, describing the ROS implementation as the basic model for other robots of these types. By controlling these robots, whether in simulation or in reality, you will use ROS to drive, move, and fly robots using ROS control.

In addition, you will learn how to further harden the virtualization offering of both libvirt (sVirt) and Docker through SELinux. By the end of the book you will know how SELinux works and how you can tune it to meet your needs.
Sven Vermeulen
Linux is a dominant player in many organizations and in the cloud. Securing the Linux environment is extremely important for any organization, and Security-Enhanced Linux (SELinux) acts as an additional layer to Linux system security. SELinux System Administration covers basic SELinux concepts and shows you how to enhance Linux system protection measures. You will get to grips with SELinux and understand how it is integrated. As you progress, you’ll get hands-on experience of tuning and configuring SELinux and integrating it into day-to-day administration tasks such as user management, network management, and application maintenance. Platforms such as Kubernetes, system services like systemd, and virtualization solutions like libvirt and Xen, all of which offer SELinux-specific controls, will be explained effectively so that you understand how to apply and configure SELinux within these applications. If applications do not exert the expected behavior, you’ll learn how to fine-tune policies to securely host these applications. In case no policies exist, the book will guide you through developing custom policies on your own.By the end of this Linux book, you’ll be able to harden any Linux system using SELinux to suit your needs and fine-tune existing policies and develop custom ones to protect any app and service running on your Linux systems.

Senior pracuje z Windows 10 to pierwsza z czterech książek wprowadzających w tajniki pracy na komputerze. Część pierwsza skupia się wokół obsługi systemu Windows 10 zainstalowanym na komputerze stacjonarnym lub przenośnym, a z myślą o osobach starszych zastosowano większą czcionkę. Książka została przygotowana w taki sposób aby użytkownik z różnym stopniem zaawansowania odnalazł coś dla siebie. Przedstawione zostały podstawowe pojęcia, nazwy związane ze sprzętem, systemem Windows i oprogramowaniem użytkowym. Po przeczytaniu książki, każdy czytelnik powinien potrafić dostosować system do swojej wygody, poukładać ikony i kafelki aplikacji, dostosować pulpit i ekran do odpowiedniej skali. Bez problemu również każdy senior uporządkuje informacje zapisane w plikach w odpowiednich segregatorach cyfrowych, zwanych folderami. Kłopotu też nie powinno przysporzyć podłączenie komputera do telewizora, dołączenie drukarki, głośnika czy myszki bezprzewodowej.
