Paperback. Condition: new. Paperback. Master the Art of High-Performance Linux EngineeringIn the era of multicore processors and massive data throughput, standard programming practices are often insufficient. True system performance is not achieved by accident; it is the result of deliberate architectural choices that align software logic with hardware capabilities. Advanced Process Management bridges the gap between theoretical operating system concepts and practical, high-performance engineering, offering a definitive guide for developers who need their code to scale.This book moves beyond basic API syntax to explore the kernel-level mechanics that drive efficiency in Linux environments. Designed for intermediate to advanced systems engineers, software architects, and C/C++ developers, it provides the technical depth required to build applications that are resilient, observable, and blazingly fast. You will learn to navigate the complexities of the Linux scheduler, manage memory pressure, and architect concurrency models that avoid common pitfalls like race conditions and deadlocks.Key Topics Covered: Linux Process Architecture: Understand the execution environment, CPU scheduling policies, and how to use processor affinity to isolate critical paths from system noise.Multithreading Mastery: A deep dive into POSIX threads (pthreads), covering advanced synchronization primitives, memory visibility, and thread safety.Inter-Process Communication (IPC): detailed implementation strategies for shared memory, message queues, and signals to ensure efficient data exchange between processes.Memory Optimization: Learn to design cache-friendly data structures and manage swap configuration to minimize latency.Concurrency Hazards: Practical patterns for detecting, preventing, and resolving deadlocks and race conditions in production systems.Whether you are optimizing a real-time analytics engine, building a scalable backend service, or simply seeking a deeper understanding of the OS, this book provides the blueprint for mastering the Linux environment. Stop fighting the scheduler and start engineering with precision. This item is printed on demand.

Paperback. Condition: new. Paperback. Master the Machinery of the Internet: A Deep Dive into Linux Kernel Networking and Server ArchitectureNetwork programming is often taught as a simple sequence of function calls. A student learns to create a socket, bind it to a port, and accept a client. In a controlled environment, this works flawlessly. In a hostile production environment, it fails.Real-world networks are unpredictable. Latency varies, packets are lost, and clients disappear without warning. If you want to build a server that rivals Nginx or a data store that performs like Redis, you need more than a superficial understanding of the API. You need to master the underlying architecture of the Linux operating system.Network Socket Programming is written for the developer who has moved beyond "Hello World" and is ready to tackle the engineering challenges of building robust, high-performance systems. This book bridges the gap between basic syntax and enterprise-scale architecture, stripping away the abstractions to reveal the mechanics of the TCP/IP stack.Key Topics Covered: The Kernel-User Boundary: Understand the true cost of system calls, context switches, and memory copying. Learn how to minimize overhead using advanced buffering strategies.Concurrency at Scale: Rigorous analysis of I/O models. Move from blocking I/O and process-forking to multi-threading, and finally to the massive scalability of I/O Multiplexing with epoll.Event-Driven Architecture: Build a non-blocking event loop from scratch. Master Edge-Triggered notifications, timer management, and signal integration to handle the C10K problem and beyond.Performance Tuning: Optimize the TCP stack using socket options. Resolve the conflict between Nagle's Algorithm and Delayed ACKs, tune buffer sizes for bandwidth-delay products, and implement keepalives that actually work.Zero-Copy Data Transfer: Eliminate the middleman. Use sendfile, splice, and mmap to move gigabytes of data directly from disk to network without touching user-space memory.Production Readiness: Implement defensive programming to handle malformed packets, prevent file descriptor leaks, and secure your connections with OpenSSL.Future Technologies: Explore the cutting edge of Linux networking, including true asynchronous I/O with io_uring, packet filtering with eBPF/XDP, and the shift to UDP-based HTTP/3 with QUIC.This is not a book of scripts; it is a guide to resource management. It teaches you how to manage CPU cycles, memory pages, and bandwidth efficiently. Whether you are writing a high-frequency trading platform, a custom proxy, or simply want to understand the machinery of the internet, this book provides the engineering decisions required for real-world scale.
