Modern Systems Programming with Scala Native »

Access the power of bare-metal systems programming with Scala Native, an ahead-of-time Scala compiler. Without the baggage of virtual machines, Scala Native re-imagines how your programs interact with your operating system. Compile Scala to native machine instructions; invoke operating system APIs for low-level networking; and enjoy instant start-up times. Skip the JVM and improve your code performance by getting close to the metal.

Do you remember this day in 1984? If you were watching the Super Bowl then, you would have seen the very first TV ad for the Apple Macintosh, bringing the GUI and mouse to the mainstream.

Fast-forward to 2020, where now we have layers upon layers of libraries, frameworks, and programs so tall we call them "stacks." Sometimes, you need to get closer to the bare metal. See how with Modern Systems Programming with Scala Native, now in print and shipping from pragprog.com/book/rwscala.

Modern Systems Programming with Scala Native: Write Lean, High-Performance Code without the JVM

Developers generally build systems on top of the work of those who came before, accumulating layer upon layer of abstraction. Scala Native provides a rare opportunity to remove layers. Without the JVM, Scala Native uses POSIX and ANSI C APIs to build concise, expressive programs that run unusually close to bare metal. Scala Native compiles Scala code down to native machine instructions instead of JVM bytecode. It starts up fast, without the sluggish warm-up phase that’s common for just-in-time compilers. Scala Native programs can seamlessly invoke operating system APIs for low-level networking and IO. And Scala Native lets you control pointers, arrays, and other memory layout types for extreme performance.

Write practical, bare-metal code with Scala Native, step by step. Understand the foundations of systems programming, including pointers, arrays, strings, and memory management. Use the UNIX socket API to write network client and server programs without the sort of frameworks higher-level languages rely on. Put all the pieces together to design and implement a modern, asynchronous microservice-style HTTP framework from scratch.

Take advantage of Scala Native's clean, modern syntax to write lean, high-performance code without the JVM.

Now in print: The ebook is content complete and available from pragprog.com/book/rwscala. For the paperback edition, please support your local independent bookstore.
