Refactoring in Java
In a time when it seems there is no other topic but artificial intelligence, it may seem strange to write a book that gathers the key practices for writing good, maintainable, and, in a word, clean code. As I write this, tools are becoming well-known – perhaps they are already well-known – that assist the developer and help write code, suggesting how to complete the line of code they are writing or even writing some short methods. Opinions at the moment are very polarized, between those who fear becoming obsolete in a few weeks and those who believe their natural intelligence is superior to any artificial intelligence.

Practical Event-Driven Microservices Architecture: Building Sustainable and Highly Scalable Event-Driven Microservices
Applications and systems came a long way since the traditional use cases of the turning of the century. You might recall measuring large data in a few gigabytes, waiting for a web page to load for a few dozens of seconds, or the scheduled maintenance that included a few hours of downtime. These were common practices perhaps 20 years ago; today, however, they are completely unacceptable. In fact, serving functionality in dozens of milliseconds and 100% uptime are properties users started getting used to and expect from any application. Achieving them at scale, however, requires a substantially different approach to how we build software and different paradigms to software architecture design

Modern CSS with Tailwind
Tailwind 3.0 adds a just-in-time (JIT) engine, which changes the way Tailwind determines what Cascading Style Sheets (CSS) code to generate and make available to the browser. Tailwind is a large set of CSS classes that each stand in for some set of CSS properties. In previous versions, Tailwind generated a list of its CSS classes and then allowed you to specify any classes in that list you wanted removed to limit the size of the Tailwind file for performance purposes.

Learn R As a Language
Why did I choose “Learn R: As a Language” as the title? This book is based on exploration and practice that aims at teaching how to express various operations on data using the R language. It focuses on the language, rather than on specific types of data analysis, exposes the reader to current usage, and does not spare the quirks of the language. When we use our native language in everyday life, we do not think about grammar rules or sentence structure, except for the trickier or unfamiliar situations.

Mathematical Methods using Python
In this introductory chapter, we present the basics of using Python, focusing on the most frequently used libraries (SymPy, NumPy, SciPy, Matplotlib). We discuss the various data types, variables and sequences, and give examples of functions, loops and conditional statements. We show how to use functions and methods and how to work with NumPy arrays using indexing and slicing. We introduce the Matplotlib library and how to set up 2D and 3D graphics. Finally, we give examples of symbolic evaluations using SymPy and how to use the lambdify function in Python.

Advanced Field-Effect Transistors
Complementary metal–oxide–semiconductor (CMOS) technology has evolved as the dominant fabrication process in the past few decades, and it has become the only option for semiconductor industries, but it’s not best suited for low-power applications. The uses of developing semiconductor devices in electronic circuits are explored throughout this book. It addresses systematic and comprehensive engineering problems as well as applications of sophisticated low-power devices.

Create Your Own Operating System
Take a look around you right now and count how many electronic devices you can see from your current point of view. If you are like most people, you probably have numerous devices just within your current eye sight. In order for many of those devices to work, they have some sort of operating system (OS) that allows them to boot up and provide whatever experiences it is they have to offer. In fact, if you are reading the digital version of this book, the very device you are now holding has an operating system of its own.

Observability with Grafana
In this book, we will use the OpenTelemetry Demo application to simulate a real-world environment and send the collected data to a free Grafana Cloud account that we will create. This administration and support tools offered by Grafana. This approach will teach you how to run the Grafana tools in a way so that anyone can experiment and learn independently.

Modern Operating Systems
The fifth edition of this book differs from the fourth edition in many ways.There are large numbers of small changes everywhere to bring the material up to date as operating systems are not standing still. For example, where the previous edition focused almost exclusively on magnetic hard disks for storage, this time we give the flash-based Solid State Drives (SSDs) the attention that befits their popularity. The chapter on Windows 8.1 has been replaced entirely by a chapter on the new Windows 11. We hav e rewritten much of the security chapter, with more focus on topics that are directly relevant for operating systems (and exciting new attacks and defenses), while reducing the discussion of cryptography and steganography. Here is a chapter-by-chapter rundown of the changes.

Moodle 4 Security
Moodle is one of the most popular learning platforms in the world. Moodle’s success is, in no small part, down to the fact that it is open source. This means the Moodle code is publicly available, and it is structured to allow the easy inclusion of third-party plugins – the vast majority of which are themselves open source. Anyone can host their own Moodle – and lots of organizations do.However, with all the advantages of open source software come great risks. A threat actor attacking your Moodle is like the persistent burglar who has an accurate layout of every room in your home and knows the precise locations of all of your most valued possessions. If you are unsure how to protect your Moodle against a devious and untrustworthy cyber enemy, then let this book be your guide.

PowerShell 7 Workshop
PowerShell is a free, powerful, and easy-to-learn programming language. Originally written as a scripting and administration tool for Windows, it’s now available as an open source resource that can be installed on almost all laptops and desktops. I have been teaching PowerShell to my colleagues for the last decade, and in my spare time, I teach coding to kids in local schools, mostly in Python. Why not teach coding with PowerShell?

Spring Quick Reference Guide: A Pocket Handbook for Spring Framework, Spring Boot, and More
Spring was initially started as an alternative to more heavy approaches to enterprise applications such as the J2EE standard. It made it possible to cleanly separate the framework from the code by allowing the configuration of POJOs (Plain Old Java Objects) rather than forcing classes to extend a certain class or implement an interface.
