Spilca L. Troubleshooting Java. Read, Debug, and Optimize JVM App 2023 torrent

Textbook in PDF format

Effectively reading and understanding existing code is a developer’s superpower. In this book, you’ll master techniques for code profiling, advanced debugging, and log evaluation to find and fix bugs and performance problems.
In Troubleshooting Java: Read, debug, and optimize JVM applications you will learn how to:
Determine what code does the first time you see it
Expose code logic problems
Evaluate heap dumps to find memory leaks
Monitor CPU consumption to optimize execution
Use thread dumps to find and solve deadlocks
Easily follow a service-oriented or microservices system
Properly use logging to better understand Java app execution
Use Java debuggers efficiently
Troubleshooting Java: Read, debug, and optimize JVM applications teaches code investigation techniques that will help you understand how Java apps work, optimize them, and fix the bugs that break them. You’ll go from the basics of debugging to advanced methods for locating problems in microservices architectures. Each new technique is explained with lively illustrations and engaging real-world examples.
about the technology
Tasks like searching for bugs, working through messy legacy code, and analyzing an application’s readiness to support new features consume a lot of developer time. In fact, most developers spend more time trying to read and understand code than they do writing it! In this unique guide, you’ll learn techniques like resolving deadlocks by examining thread dumps and locating memory leaks by inspecting the heap that will radically improve your efficiency when working with existing code in JVM languages like Java, Scala, and Kotlin.
about the book
Troubleshooting Java: Read, debug, and optimize JVM applications teaches you how to better understand Java application code. It’s filled with code investigation techniques for tricky issues like uncovering glitches in code logic or locating intermittent runtime problems. Armed with these tools and practices you’ll save time whenever you need to identify performance issues, understand dependencies, discover the root cause of crashes, or interpret unexpected results. Whether you’re a senior software engineer or you’re just getting started, this invaluable guide will help you in the fundamental task of understanding how your applications work.
What does a software developer actually do for a living? “Implement software” is the most common answer to this question. But what does that mean? Is it only writing code? Well, no. While it is true that code is the result of everything a software developer does, the activity of writing code takes only a small part of a software developer’s working time. Most of a software developer’s time is actually used designing solutions, reading existing code, understanding how it executes, and learning new things. Writing code is the result of a software developer successfully accomplishing all of these tasks. Therefore, a programmer spends most of their time reading existing solutions rather than effectively writing new capabilities.
Clean coding as a subject has, in the end, the same purpose: teaching developers how to write easier-to-read solutions. Developers realize that it’s more efficient to write an easier-to-read solution from the beginning than spend time trying to understand it later. But we need to be honest and admit that not all solutions are clean enough to quickly comprehend. We’ll always face scenarios in which we will need to understand the execution of some foreign capability. The reality is that software developers spend a lot of time investigating how apps work. They read and examine code in their app’s codebases and associated dependencies to figure out why something doesn’t work the way they expect.
