You'll also take a deep dive into the virtual threads introduced as Project Loom in Java 19 and become familiar with the public release of JDK 21 LTS. This guide helps you: Learn the structure of the Java language and Java applications Write, compile, and execute Java applications Understand the basics of Java threading and concurrent programming Learn Java I/O basics, including local files and network resources Create compelling interfaces with an eye toward usability Learn how functional features have been integrated in Java Keep up with Java developments as new versions are released

GNU Emacs is the most popular and widespread of the Emacs family of editors. It is also the most powerful and flexible. Unlike all other text editors, GNU Emacs is a complete working environment--you can stay within Emacs all day without leaving. "Learning GNU Emacs," 3rd Edition tells readers how to get started with the GNU Emacs editor. It is a thorough guide that will also "grow" with you: as you become more proficient, this book will help you learn how to use Emacs more effectively. It takes you from basic Emacs usage (simple text editing) to moderately complicated customization and programming.

The third edition of "Learning GNU Emacs" describes Emacs 21.3 from the ground up, including new user interface features such as an icon-based toolbar and an interactive interface to Emacs customization. A new chapter details how to install and run Emacs on Mac OS X, Windows, and Linux, including tips for using Emacs effectively on those platforms.

"Learning GNU Emacs," third edition, covers:

How to edit files with Emacs

Using the operating system shell through Emacs

How to use multiple buffers, windows, and frames

Customizing Emacs interactively and through startup files

Writing macros to circumvent repetitious tasks

Emacs as a programming environment for Java, C++, and Perl, among others

Using Emacs as an integrated development environment (IDE)

Integrating Emacs with CVS, Subversion and other change control systems for projects with multiple developers

Writing HTML, XHTML, and XML with Emacs

The basics of Emacs Lisp

The book is aimed at new Emacs users, whether or not they are programmers. Also useful for readers switching from other Emacsimplementations to GNU Emacs.

For makers looking to use the smallest controllers or wring the highest performance out of larger controllers, the C language is still the best option. This practical book provides a solid grounding in C basics for anyone who tinkers with programming microcontrollers. You'll explore many ways C enables developers and makers to get big results out of tiny devices. Author Marc Loy shows you how to write clean, maintainable C code from scratch. This language and its C++ cousin are still widely used to write low-level code for device drivers or operating systems. By understanding C syntax and quirks, you'll gain an enduring computer language literacy that will help you pick up new languages and styles more easily. Learn C fundamentals including data types, flow control, and functions Explore memory management including how programs work on small devices Understand answers provided in online forums such as Reddit or Stack Overflow Write efficient, custom C code that's both readable and maintainable Analyze the performance of your code and weigh optimizations Evaluate third-party libraries for use in your own projects Create your own libraries to share with others
