Hardcore Developers Bundle

This book takes intermediate to advanced C++ developers on a comprehensive journey through the C++23 standard (ISO/IEC 14882:2024). You will learn every significant language and library feature added in this release, understand the design rationale behind each decision, and see how to apply them effectively in production software. From error handling with `std::expected` to formatted output with `std::print`, from multidimensional data access with `std::mdspan` to coroutine-based generators, this guide covers the tools that make modern C++ safer, more expressive, and more maintainable without sacrificing performance. Each chapter includes production-quality code examples, performance considerations, migration strategies from earlier standards, and practical exercises to solidify your understanding.

eBPF is the most transformative technology in modern systems programming. It lets you run safe, high-performance programs inside the Linux kernel without modifying kernel source or loading kernel modules. This book takes you from zero eBPF experience to production-ready expertise through a progressive series of complete, working code examples. You will learn the architecture (verifier, maps, helpers, BTF), the toolchain (libbpf, CO-RE, bpftrace, bpftool), and real-world applications across networking (XDP, TC), tracing (kprobes, uprobes, tracepoints, fentry/fexit), security (LSM), performance profiling, container observability, and Kubernetes integration. Every concept is demonstrated with end-to-end source code you can compile and run yourself.

Modern software architecture is no longer about choosing a single paradigm. It is about composing multiple paradigms intelligently, managing the inherent complexity of distributed systems, and building systems that evolve alongside changing business requirements and technological capabilities. This book takes experienced developers and architects on a deep journey through microservices, event-driven systems, serverless computing, complex design patterns, scalability strategies, resilience engineering, observability, security architecture, multi-cloud strategies, and emerging trends like AI-driven architecture and quantum computing implications. Every chapter combines rigorous technical analysis with real-world case studies from companies like Netflix, LinkedIn, Twitter, Uber, ING Bank, and Google, providing the practical wisdom needed to make sound architectural decisions in production environments.

This book is for senior iOS engineers who build and maintain complex production applications. It covers the full spectrum of modern iOS development on iOS 27 with Swift 6, from language evolution and concurrency safety to architectural patterns, modularization, data persistence, networking, security, testing, CI/CD, and Apple's expanding AI ecosystem. Every chapter is grounded in real-world engineering trade-offs rather than textbook abstractions. Code examples are production-ready, and architectural decisions are justified with measurable outcomes. If you have shipped iOS apps before and want to understand how to build systems that scale across teams, platforms, and years of platform evolution, this book is for you.

You have used web frameworks. You know how to spin up an Axum or Actix server in minutes. But do you understand what happens when a browser sends a request and your server sends back a response? This book takes you on a hands-on journey from raw TCP sockets through the full stack of HTTP/1.1, HTTP/2, TLS, routing, middleware, templating, REST APIs, testing, benchmarking, and deployment. Every chapter adds a layer to a production-quality web server built entirely in Rust using Tokio and carefully chosen crates. By the end, you will not only have a working server but also the deep intuition that makes you a better developer no matter what tools you eventually use.
