Functional Programming

This Developer's Guide is the "Project #1" from the also included "Building Role-Playing Browser Games" workbook. It leads you through the development of the "St. George Battles the Dragons" Role-Playing Game in both Construct v3 & v2 encoding. It's perfect for novices, experienced web developers, and anyone wanting their own bespoke game, artwork, and features.

Most blockchain books teach the theory. This one walks you through building a complete Bitcoin-style blockchain in Rust, end to end — cryptography, consensus, networking, persistence, REST API, desktop wallets, and Kubernetes deployment.

An introduction to actor-critic algorithms as dynamical systems: featuring hand-computable examples, fast-slow reductions, and machine-checked Lean 4 proofs

Clean, Hexagonal, Onion—one dependency rule, three names. Walk a runnable multi-module SaaS billing service in Scala 3 and ZIO: a pure domain ring, ports and use cases in the middle, PostgreSQL + Flyway + JDBC and a thin HTTP shell on the outside—with full source in the PDF, not truncated snippets. See how ZLayer at the composition root keeps one repository for the whole graph, how webhook idempotency stays on the right side of the boundary, and how munit and zio-test (plus optional Docker) prove the architecture you intend to defend in code review.

CRUD erases the story your system lived through; event sourcing keeps it. Build an account aggregate in Scala 3 and ZIO: past-tense events, a pure applyEvent fold, decide for invariants and idempotency, then wire an append-only PostgreSQL journal, transactions, and a balance projection—and trace one account from HTTP command to read model. When the log must leave the database, follow the same events through transactional outbox, Kafka, and at-least-once consumers without pretending you have magic consistency. For architects and implementers who want decision-grade ES + CQRS, not a toy demo.

No distributed transaction spans your whole business process—so you design steps and compensations instead. In Scala 3 and ZIO, build a full order-placement saga from domain types and service algebras to orchestration and event-driven choreography, with tests that prove compensations fire when things break. Then see what it takes to move the same design toward production: outbox, idempotency, persistence, and how to choose between central coordination and decentralized reactions.

This chapter is part of the "Construct Gamer Starter Kit" collection and provides a guide to developing Memory Matching games, including MahJong, Hidden Pairs, and "Sequence 3+." The tutorial includes coding for both Construct v2 and v3, making it suitable for beginners and experienced web developers alike. It's perfect for anyone looking to create their own customized Memory Matching games with unique artwork and features.

Write code that you can understand without holding the entire system in your head. This book shows you how Java's modern functional features—records, sealed types, lambdas, streams—combine into a powerful approach to design. You'll learn: • How to eliminate race conditions without synchronized blocks • How to write tests that test business logic, not mock frameworks • How to compose complex behaviors from simple, reusable functions • How to manage deeply nested immutable data without boilerplate • How to adopt functional patterns incrementally in existing codebases Written for working developers. Filled with production-ready code examples.

Stop debating code style. Start engineering code. Every developer brings personal preferences. Every AI tool channels different training examples. The result? Inconsistent codebases, endless code reviews, and technical debt that compounds silently. Java Backend Coding Technology introduces a radical idea: reduce the space of valid choices until there's essentially one good way to do most things. Not through rigid frameworks, but through a small set of patterns that make structure predictable, refactoring mechanical, and business logic visible. The code you write, your teammate writes, and your AI assistant generates will look the same -- because the patterns leave no room for subjective variation.

This book is your ultimate roadmap to modern React.js interviews and standing out from the crowd.Built on 350+ real interview insights, it covers the exact topics top companies test—from security, accessibility, and performance to TypeScript, architecture, and deployment—so you can master every question with confidence and land the role you deserve.

Python is a multi-paradigm language. Beginners use it a procedural language.Intermediate users learn Object Oriented Python programming. Advanced user use the Functional Programming features of the language.This books helps you to become and advanced Python programmer who understand and can use the functional programming constructs of the language.

Are you scared by mathematical symbols or formal terms like "monad"? Unwrapping Monads & Friends offers a clear, approachable path through functional programming’s most intimidating concepts—no math degree required. If you've ever said "I kind of get it, but not really," this is the guide that finally makes it click.

This is a workbook from the Construct Game Starter Kit Collection. It leads you through three (3) "Trivia Quiz & Dating" games for both Construct v3 & v2 encoding. It's perfect for novices, experienced web developers, and just anyone wanting their own bespoke game, artwork, and features.
