Go

This series of test-driven small coding puzzles lets you code a database from scratch (no dependencies).We'll cover KV storage engines, LSM-Tree indexes, SQL, concurrent transactions, ACID, etc.

Learn databases from the bottom up by coding your own, in small steps, and with simple Go code (language agnostic).Atomicity & durability. A DB is more than files!Persist data with fsync.Crash recovery.KV store based on B-tree.Disk-based data structures.Space management with a free list.Relational DB on top of KV.Learn how tables and indexes are related to B-trees.SQL-like query language; parser & interpreter.Concurrent transactions with copy-on-write data structures.

A practical guide to Microsoft Desired State Configuration (DSC), the cross-platform configuration management tool for Windows, Linux, and macOS. Learn how to author configuration documents, work with built-in resources, adapters, and build custom resources.

Go beyond Go syntax and learn how real systems are built. Modern Go Systems Programming with Go 1.27 takes you from core language concepts to concurrency, networking, databases, observability and deployment, with runnable examples that show how everything fits together in production-grade distributed systems.

Build a game from scratch in Go, no engine magic, just code you understand. You'll create Gopher Survivor, a Vampire Survivors–style action game, one concept per chapter: enemies, weapons, XP and level-ups, particles, a state machine, and a build you can ship.

What if S3 could be more than a place to put files? Build databases, queues, event logs, Git systems and distributed applications directly on object storage. Through production-grade Go implementations, this book explores what works, what breaks and how to design reliable systems around the real guarantees of S3-compatible storage.

Build terminal apps that feel fast, polished and built to last. Terminal Interfaces takes you from the fundamentals of how terminals work to production-ready TUIs in Go, Python and Rust, using complete examples that grow from simple programs into powerful real-world tools.

In this book you will learn the following: Build Console appsCreate Web APIsTest your codeCreate and publish reusable packages that others can consumeOrganize your files in a projectWork with files and directoriesParse text with the string library and regular expressions.

Working with Go effectively, requires proficiency and understanding beyond learning the simple syntax. It can take developers months or even years to acquire this experience, especially those coming from OOP. This book sets out to short-circuit that process and get you there faster! Includes Generics.

AI can write code at machine speed. Can your architecture keep up? Architecture at Machine Speed shows how to build Go systems that remain coherent as humans and AI agents change them at unprecedented velocity. Through a real-world application built from the ground up, you'll learn to turn architectural intent into explicit boundaries, enforceable constraints, and automated safeguards—because when code becomes abundant, coherence becomes the scarce resource.

From the Linux basics to advanced development workflows, this practical guide shows you how to turn Linux into a powerful software development environment. Learn the command line, work with popular programming languages, use containers and CI/CD, debug and profile applications and build skills you can use every day.

Whenever I've worked on a service, there's always been a morning when it stops being a demo. Then traffic arrives from somewhere nobody planned for, a nightly job overruns into the working day, and a number somebody chose months ago turns out to be wrong. That morning was a different story, though. The thing that separates a survival program from one that doesn't is a set of habits, and those habits can be learned. So, this second edition is organised around them rather than around syntax.

Discover G#, a modern .NET language built for developers who want less friction and more clarity. Go from your first line of code to production-ready applications while exploring the simplicity of Go, the expressive feel of Kotlin and Swift and the power of the CLR. Practical examples and real-world guidance make every chapter count.
