这是 Swift4.2 的，PDF 版，Language Guide 部分是带目录标签，其他部分无目录标签（你几乎不会去看的） Swift is a fantastic way to write software, whether it’s for phones, desktops, servers, or anything else that runs code. It’s a safe, fast, and interactive programming language that combines the best in modern language thinking with wisdom from the wider Apple engineering culture and the diverse contributions from its open-source community. The compiler is optimized for performance and the language is optimized for development, without compromising on either.

DTrace provides a powerful infrastructure to permit administrators, developers, and service personnel to concisely answer arbitrary questions about the behavior of the operating system and user programs. The illumos Dynamic Tracing Guide describes how to use DTrace to observe, debug, and tune system behavior. This book also includes a complete reference for bundled DTrace observability tools and the D programming language. This illumos release supports systems that use the SPARCTM and x86 families of processor architectures: UltraSPARCTM, SPARC64, AMD64, Pentium, and Xeon EM64T. The supported systems appear in the illumos Hardware Compatibility List. This document cites any implementation differences between the platform types. In this document the term “x86” refers to 64–bit and 32–bit systems manufactured using processors compatible with the AMD64 or Intel Xeon/Pentium product families. For supported systems, see the illumos Hardware Compatibility List. Who Should Use This Book If you have ever wanted to understand the behavior of your system, DTrace is the tool for you. DTrace is a comprehensive dynamic tracing facility that is built into illumos. The DTrace facility can be used to examine the behavior of user programs. The DTrace facility can also be used to examine the behavior of the operating system. DTrace can be used by system administrators or application developers, and is suitable for use with live production systems. DTrace will allow you to explore your system to understand how it works, track down performance problems across many layers of software, or locate the cause of aberrant behavior. As you'll see, DTrace lets you create your own custom programs to dynamically instrument the system and provide immediate, concise answers to arbitrary questions you can formulate using the DTrace D programming language. DTrace allows all il

Using DTrace, you can dynamically instrument software and quickly answer virtually any question about its behavior. Now, for the first time, there's a comprehensive, authoritative guide to making the most of DTrace in any supported UNIX environment--from Oracle Solaris to OpenSolaris, Mac OS X, and FreeBSD. Written by key contributors to the DTrace community, DTrace teaches by example, presenting scores of commands and easy-to-adapt, downloadable D scripts. These concise examples generate answers to real and useful questions, and serve as a starting point for building more complex scripts. Using them, you can start making practical use of DTrace immediately, whether you're an administrator, developer, analyst, architect, or support professional. The authors fully explain the goals, techniques, and output associated with each script or command. Drawing on their extensive experience, they provide strategy suggestions, checklists, and functional diagrams, as well as a chapter of advanced tips and tricks. You'll learn how to Write effective scripts using DTrace's D language Use DTrace to thoroughly understand system performance Expose functional areas of the operating system, including I/O, filesystems, and protocols Use DTrace in the application and database development process Identify and fix security problems with DTrace Analyze the operating system kernel Integrate DTrace into source code Extend DTrace with other tools This book will help you make the most of DTrace to solve problems more quickly and efficiently, and build systems that work faster and more reliably.

1，英文版；2，带目录 You've experienced the shiny, point-and-click surface of your Linux computer-now dive below and explore its depths with the power of the command line. The Linux Command Line takes you from your very first terminal keystrokes to writing full programs in Bash, the most popular Linux shell. Along the way you'll learn the timeless skills handed down by generations of gray-bearded, mouse-shunning gurus: file navigation, environment configuration, command chaining, pattern matching with regular expressions, and more. In addition to that practical knowledge, author William Shotts reveals the philosophy behind these tools and the rich heritage that your desktop Linux machine has inherited from Unix supercomputers of yore. As you make your way through the book's short, easily-digestible chapters, you'll learn how to: * Create and delete files, directories, and symlinks * Administer your system, including networking, package installation, and process management * Use standard input and output, redirection, and pipelines * Edit files with Vi, the world's most popular text editor * Write shell scripts to automate common or boring tasks * Slice and dice text files with cut, paste, grep, patch, and sed Once you overcome your initial "shell shock," you'll find that the command line is a natural and expressive way to communicate with your computer. Just don't be surprised if your mouse starts to gather dust.

I’m delighted that you’ve picked up this book and excited to join you in exploring the topic of concurrency in Go over the next six chapters! Go is a wonderful language. When it was first announced and birthed into the world, I remember exploring it with great interest: it was terse, compiled incredibly fast, performed well, supported duck typing, and — to my delight — I found working with its concurrency primitives to be intuitive. The first time I used the go keyword to create a goroutine (something we’ll cover, I promise!) I got this silly grin on my face. I had worked with concurrency in several languages, but I had never worked in a language that made concurrency so easy (which is not to say they don’t exist; I just hadn’t used any). I had found my way to Go. Over the years I moved from writing personal scripts ” ......
