Want to master the BPF virtual machine in the Linux Kernel? This practical guide shows you how to write applications that use BPF to observe and modify the kernel’s behavior on demand—without having prior knowledge of Linux Kernel development. David Calavera and Lorenzo Fontana introduce concepts to help systems engineers understand the BPF program lifecycle.
If you have knowledge about performance optimization, networking, and security, this book shows you how to inject code to monitor, trace, and observe events in the kernel in a secure way—without the need to recompile the kernel or reboot the system. You’ll find code examples in C, Go, and Python.

This is the story of Linus Torvalds, the maverick Finnish computer genius who invented the powerful LINUX operating system. As well as being free, LINUX is more powerful and stable than anything that Microsoft can offer, thus making Torvalds Bill Gates' number one enemy. Today, LINUX is exploding on to the market, and its creator is household. Linus Torvalds is already a folk hero within the technolgy world, often mobbed at trade shows and forever asked to give interviews by the media. But Torvalds is a most unlikely celebrity: a family man, he lives in a cramped house in Santa Clara with his wife, Tove, a Finnish karate champion, and their two daughters. He claims to this day that he invented LINUX "just for fun". --This text refers to an out of print or unavailable edition of this title.

Virtual Machine technology applies the concept of virtualization to an entire machine, circumventing real machine compatibility constraints and hardware resource constraints to enable a higher degree of software portability and flexibility. Virtual machines are rapidly becoming an essential element in computer system design. They provide system security, flexibility, cross-platform compatibility, reliability, and resource efficiency. Designed to solve problems in combining and using major computer system components, virtual machine technologies play a key role in many disciplines, including operating systems, programming languages, and computer architecture. For example, at the process level, virtualizing technologies support dynamic program translation and platform-independent network computing. At the system level, they support multiple operating system environments on the same hardware platform and in servers. Historically, individual virtual machine techniques have been developed within the specific disciplines that employ them (in some cases they aren't even referred to as 'virtual machines'), making it difficult to see their common underlying relationships in a cohesive way. In this text, Smith and Nair take a new approach by examining virtual machines as a unified discipline. Pulling together cross-cutting technologies allows virtual machine implementations to be studied and engineered in a well-structured manner. Topics include instruction set emulation, dynamic program translation and optimization, high level virtual machines (including Java and CLI), and system virtual machines for both single-user systems and servers. The book examines virtual machine technologies across the disciplines that use them-operating systems, programming languages and computer architecture-defining a new and unified discipline. It is reviewed by principle researchers at Microsoft, HP, and by other industry research groups; and written by two authors who combine several decades of expertise in computer system research and development, both in academia and industry.
