The Ultimate Ubuntu Handbook. A complete guide to Ubuntu 24.04, from installation to advanced security and development

Ken VanDine, Alan Pope

Ubuntu 24.04 brings powerful new features, but most users barely scratch the surface of its potential. This book transforms you from a basic user into an Ubuntu power user by guiding you through setup, security, and development workflows step by step. Ken VanDine reveals insider knowledge and proven strategies that turn Ubuntu into a stable, secure, and productive development platform.Starting with Ubuntu’s mission, release lifecycles, and what’s new in 24.04, you’ll learn how to install the system, customize your desktop, and use the command line to work more efficiently. The book shows you how to apply updates, activate Ubuntu Pro, configure firewalls, and secure data with full disk encryption before covering topics often overlooked by desktop users. Moving into advanced territory, this book covers container-based development using LXD, working with virtual machines through Multipass, and setting up Kubernetes with MicroK8s. Whether you’re building cloud-native apps or data science projects, you’ll benefit from reliable and repeatable Ubuntu workflows. Beyond the technical skills, you'll discover how to tap into Ubuntu's global community for ongoing support and opportunities to contribute. This book is ideal for both newcomers eager to accelerate their Linux journey and seasoned professionals seeking to maximize their Ubuntu expertise.

Demystifying Cryptography with OpenSSL 3.0. Discover the best techniques to enhance your network security with OpenSSL 3.0

Alexei Khlebnikov, Jarle Adolfsen

Security and networking are essential features of software today. The modern internet is full of worms, Trojan horses, men-in-the-middle, and other threats. This is why maintaining security is more important than ever.OpenSSL is one of the most widely used and essential open source projects on the internet for this purpose. If you are a software developer, system administrator, network security engineer, or DevOps specialist, you’ve probably stumbled upon this toolset in the past – but how do you make the most out of it? With the help of this book, you will learn the most important features of OpenSSL, and gain insight into its full potential.This book contains step-by-step explanations of essential cryptography and network security concepts, as well as practical examples illustrating the usage of those concepts. You’ll start by learning the basics, such as how to perform symmetric encryption and calculate message digests. Next, you will discover more about cryptography: MAC and HMAC, public and private keys, and digital signatures. As you progress, you will explore best practices for using X.509 certificates, public key infrastructure, and TLS connections.By the end of this book, you’ll be able to use the most popular features of OpenSSL, allowing you to implement cryptography and TLS in your applications and network infrastructure.

Distributed Machine Learning with Python. Accelerating model training and serving with distributed systems

Guanhua Wang

Reducing time cost in machine learning leads to a shorter waiting time for model training and a faster model updating cycle. Distributed machine learning enables machine learning practitioners to shorten model training and inference time by orders of magnitude. With the help of this practical guide, you'll be able to put your Python development knowledge to work to get up and running with the implementation of distributed machine learning, including multi-node machine learning systems, in no time. You'll begin by exploring how distributed systems work in the machine learning area and how distributed machine learning is applied to state-of-the-art deep learning models. As you advance, you'll see how to use distributed systems to enhance machine learning model training and serving speed. You'll also get to grips with applying data parallel and model parallel approaches before optimizing the in-parallel model training and serving pipeline in local clusters or cloud environments. By the end of this book, you'll have gained the knowledge and skills needed to build and deploy an efficient data processing pipeline for machine learning model training and inference in a distributed manner.

Nagios Core Administration Cookbook. The ideal book for System Administrators who want to move their network monitoring to an advanced level. This book covers the powerful features and flexibility of Nagios Core, and its recipes can be applied to virtually any network

Tom Ryder

Network monitoring requires significantly more than just pinging hosts. This cookbook will help you to comprehensively test your networks' major functions on a regular basis.Nagios Core Administration Cookbook will show you how to use Nagios Core as a monitoring framework that understands the layers and subtleties of the network for intelligent monitoring and notification behaviour. Nagios Core Administration Guide introduces the reader to methods of extending Nagios Core into a network monitoring solution. The book begins by covering the basic structure of hosts, services, and contacts and then goes on to discuss advanced usage of checks and notifications, and configuring intelligent behaviour with network paths and dependencies. The cookbook emphasizes using Nagios Core as an extensible monitoring framework. By the end of the book, you will learn that Nagios Core is capable of doing much more than pinging a host or to check if websites respond.
