 DEBIAN 13 HOMELAB PROJECTS: Build a NAS, Media Server, Docker Infrastructure, VPN, and Self-Hosted Cloud with Secure, Real-World Linux Setups (Precision Engineering Book 6) English | May 31, 2026 | ASIN: B0H3GL67RM | 692 pages | Epub | 524.98 KB Have you ever wanted to build your own server but felt overwhelmed by the complexity of Linux infrastructure?Are you tired of tutorials that seem to work perfectly-until storage, networking, containers, backups, security, and remote access all need to function together?Do you want complete control over your files, media, backups, and cloud services without depending on expensive subscriptions and third-party platforms?If those challenges sound familiar, this book was written for you.Debian 13 Homelab Projects is a practical, project-based guide to building a complete self-hosted infrastructure using one of the world's most trusted Linux distributions. Rather than focusing on isolated commands or one-off demonstrations, it teaches you how to deploy, secure, and maintain real services that work together as a reliable ecosystem.Whether you are setting up your first server or expanding an existing homelab, this guide helps you move beyond simply installing software and begin thinking like a systems administrator who designs infrastructure for reliability, security, and long-term growth.This is where the transition begins:From scattered tutorials to a complete infrastructure strategy.From renting services to owning your digital environment.From uncertainty about Linux administration to confident deployment and management.From reactive troubleshooting to proactive operations.From experimentation to dependable self-hosted services.Built around modern Debian 13, every project contributes to a larger infrastructure foundation while developing skills that transfer directly into Linux administration, self-hosting, DevOps, and IT operations.Inside this book, you will learn how to:✔ Build a reliable Debian-based homelab from the ground up✔ Deploy a NAS for centralized storage, backups, and file sharing✔ Create a secure media server for streaming and content management✔ Build Docker-based infrastructure for scalable service deployment✔ Configure VPN access for secure remote connectivity✔ Deploy self-hosted cloud services under your complete control✔ Implement practical security and hardening practices✔ Design networks for performance, segmentation, and reliability✔ Automate routine administrative tasks✔ Monitor infrastructure health and identify problems early✔ Troubleshoot Linux, networking, and service failures systematically✔ Develop backup and disaster recovery strategies that protect critical dataMany Linux books teach commands. Many homelab guides focus only on installation. Many self-hosting resources assume years of prior experience and leave critical decisions unexplained.This book takes a different approach.You will learn not only how to deploy services, but also why architectural decisions matter. Instead of copying commands without context, you will develop the reasoning skills needed to evaluate technologies, solve problems, and build infrastructure that remains reliable long after the initial setup is complete.Along the way, you will gain hands-on experience with storage design, Docker ecosystems, VPN technologies, networking, monitoring, backup strategies, automation workflows, and infrastructure maintenance practices used in real operational environments.Whether your goal is to create a personal cloud, centralize family storage, host your own services, strengthen your Linux administration skills, or reduce dependence on commercial platforms, this guide provides a clear and practical path forward.If you're ready to take control of your data, build reliable self-hosted services, and create a homelab that actually works, this book will show you exactly how to get there.

Crystals, Copper, and the Search for Hidden Patterns: Sacred Geometry, Ancient Measurement, and the Line Between Science and Belief English | May 10, 2026 | ASIN: B0H19BXRD9 | 133 pages | Epub | 1.73 MB Crystals. Copper. Geometry. Measurement. Frequency.These ideas appear across history - in tools, structures, materials, and modern systems.They are often presented as connected.Sometimes as meaningful.Sometimes as something more.But what actually holds up?This book takes a different approach.Instead of proving or dismissing, it separates what can be clearly shown from what is interpreted - and keeps those lines visible.Inside, you'll explore:How quartz actually forms - and what it can and cannot doWhy copper has been used for thousands of years - and where modern claims extend beyond thatHow geometry began as a practical system - before becoming symbolicWhy measurement systems like the cubit existed - and how they are interpreted todayWhat "frequency" really means - and how the term is often misusedWhy patterns feel powerful - without requiring hidden explanationshow modern systems (including tensor rings) are described - and what can be supportedThis is not a book of claims.It is a book of clarity.Using a simple three-lens approach - historical, material, and experiential - it allows you to:understand what different cultures actually didrecognise what can be measured and testedmake sense of what people report and experiencewithout merging them into a single explanation.You don't need to believe anything to read this book.You only need curiosity.  Cryptography Algorithms Workbook: A Practical Guide to Modern Encryption and Security English | June 12, 2026 | ASIN: B0H4ZY63MY | 374 pages | Epub | 210.80 MB Cryptography Algorithms WorkbookA Visual Problem-Solving Workbook for Encryption, Hashing, MACs, Key Exchange, Digital Signatures, Password Hashing, TLS, Key Management, and Post-Quantum CryptographyThis workbook is built for developers, security engineers, and students who want to understand how cryptographic algorithms actually work - not just what to call, but why each primitive exists, how it can be misused, and how to use it correctly. It covers the full stack of applied cryptography, from XOR and entropy through AES and authenticated encryption, to TLS 1.3, post-quantum algorithms, and key management, with worked examples, guided exercises, practice problems, and complete answer keys in every chapter.Every chapter is structured around a security problem. You learn what the threat is, which primitive solves it, what correct use looks like, and what misuse looks like - with a defensive implementation checklist at the end of each chapter to reinforce safe practice.What this workbook covers:* Cryptographic goals: confidentiality, integrity, authentication, non-repudiation, and forward secrecy* Bits, bytes, XOR, encoding, entropy, randomness, and CSPRNGs* Keys, nonces, IVs, salts, peppers, tags, and security parameters* Security notions: IND-CPA, IND-CCA, EUF-CMA, and AEAD security* Stream ciphers, the one-time pad, and keystream reuse attacks* Block ciphers and AES: round structure, SubBytes, ShiftRows, MixColumns, and the avalanche effect* Block cipher modes: ECB, CBC, CTR, XTS, padding oracles, and mode misuse* Authenticated encryption: AEAD, AES-GCM, GMAC, and ChaCha20-Poly1305* Lightweight cryptography and the Ascon family for constrained devices* Hash functions: SHA-2, SHA-3, collision and preimage resistance, and the birthday bound* Message authentication codes: HMAC, CMAC, GMAC, and KMAC* Key derivation: HKDF, extract-then-expand, and key separation* Password hashing: Argon2id, scrypt, bcrypt, PBKDF2, salts, and peppers* RSA: textbook vs. secure use, OAEP, PSS, and why padding matters* Diffie-Hellman, ECDH, elliptic curves, and forward secrecy* Digital signatures: RSA-PSS, ECDSA, EdDSA, and the ECDSA nonce requirement* Public-key infrastructure: certificates, trust chains, revocation, and certificate transparency* Post-quantum cryptography: ML-KEM, ML-DSA, SLH-DSA, hybrid migration, and crypto-agility* TLS 1.3: the handshake, key schedule, cipher suites, forward secrecy, and 0-RTT* Key management: key lifecycle, HSMs, KMS, envelope encryption, and side-channel disciplineWhat makes this workbook useful:* Every chapter opens by framing the security problem before introducing the solution* Worked examples, guided exercises, and practice problems in every chapter* Complete answer keys with reasoning, not just answers* Common mistake sections identifying exactly where implementations go wrong* Defensive implementation checklists at the end of every chapter* Algorithm selection tables and primitive reference appendices* A comprehensive cryptographic misuse checklist and secure implementation guideGood for:* Software developers implementing cryptography in real systems* Security engineers and architects designing secure protocols* Students in applied cryptography, information security, or computer science courses* Developers preparing for security certifications or code review* Anyone who wants to move from "copy-paste the example" to genuinely understanding what each parameter does and why it mattersIf you want a workbook that teaches you applied cryptography from the threat model down - covering not just the algorithms but the misuse patterns that get real systems broken - this book is built for that.  Critical Thinking in the Age of AI: How to Reason, Question, and Flourish in a World of Intelligent Machines English | May 13, 2026 | ASIN: B0H1P37ZR3 | 108 pages | Epub | 171.01 KB Artificial intelligence is transforming how we think, learn, communicate, and make decisions. But as machines become increasingly capable of generating ideas, solving problems, and simulating human reasoning, a deeper question emerges:Are we still thinking for ourselves?In Critical Thinking in the Age of AI, B.A. Moss explores the evolving relationship between human cognition and intelligent machines. Blending philosophy, cognitive science, ethics, and real-world examples, this book examines how AI can both augment and undermine our ability to reason clearly and independently.From cognitive biases and algorithmic influence to AI-generated misinformation and the outsourcing of thought itself, Moss challenges readers to confront one of the defining questions of our era: What does it mean to think critically in a world increasingly shaped by artificial intelligence?Accessible yet intellectually rigorous, this book is ideal for students, educators, professionals, and anyone seeking to navigate the opportunities and risks of the AI age with greater clarity, skepticism, and wisdom.Rather than rejecting technology, Critical Thinking in the Age of AI argues for a more thoughtful path forward-one in which AI becomes a tool for augmented thinking rather than a replacement for human judgment.In an age of intelligent machines, the most important skill may still be the ability to think for ourselves.  Critical Thinking in the Age of AI: A Framework for Rational Decision-Making (Rational Thinking Book 1) English | May 21, 2026 | ASIN: B0H2J53Q6W | 411 pages | Epub | 13.50 MB You can't outsmart AI by knowing more. AI already knows more than you ever will.What only humans can do - and must keep doing - is decide what counts as "right."This book teaches you how.--Critical Thinking in the Age of AI presents a systematic framework for rational decision-making, built around eleven concrete conditions that any sound argument must meet. Unlike books that offer "tips" or "hacks," this is a foundational text: it teaches the structure of rationality itself, so you can apply it to any decision, in any domain.What you'll learn:How to distinguish three types of questions - value, factual, and action - and why mixing them is the most common reasoning failure todayHow to evaluate any decision / argument using the Question / Claim / Premises structureHow to recognize and resist authoritarianism in your own thinking - including the new form, "AI authoritarianism," that will dominate the 2030sWhere AI helps and where it cannot replace human judgmentHow to use Custom AI as a thinking partner, with ready-made custom instructions available on the companion website--This book is for:Professionals who make consequential decisions and want a defensible frameworkEducators and researchers who teach critical thinking and want a more systematic approach than "spot the fallacy"Anyone who senses that AI is changing how we think - and wants to understand how to keep thinking for themselvesVolume 1 of the Rational Thinking series. Subsequent volumes will cover the remaining conditions of rationality.Originally published in Japanese (2024) as Shikō no Susume. This English edition is fully revised, with new material on AI throughout. |
