Hast du dich schon einmal gefragt, wie sehr dein Leben still und leise von dem geprägt wird, was du jeden Tag antippst, teilst, anklickst und wem du vertraust?Aufzuwachsen in einer vernetzten Welt bedeutet Freiheit, Spaß und unzählige Möglichkeiten - aber auch versteckte Belastungen, widersprüchliche Signale und Risiken, die selten klar erklärt werden. Viele Jugendliche bewegen sich schnell durch Apps, Chats und Plattformen, ohne wirklich zu erkennen, wie ihre Entscheidungen langfristige Spuren hinterlassen können, wie glaubwürdig wirkende Fremde auftreten oder wie kleine Unaufmerksamkeiten sich unbemerkt zu größeren Problemen entwickeln. Das Problem ist nicht mangelnde Intelligenz oder Neugier, sondern fehlende Orientierung, die sich echt anfühlt, verständlich ist und ohne Angst, Vorurteile oder Überforderung auskommt.Was Jugendliche in diesem Buch begegnet:Wiedererkennbare Situationen aus dem digitalen AlltagRealistische Online-Momente ohne ÜbertreibungTypische Entscheidungen, die viele ohne klare Anleitung treffenDenkanstöße, die Ruhe fördern statt PanikWarum Eltern und Lehrkräfte dieses Buch schätzen:Fördert Bewusstsein ohne Belehrungen oder SchuldzuweisungenNutzt klare, altersgerechte SpracheStärkt gesundes Denken statt strenger RegelnUnterstützt Verantwortung bei gleichzeitiger SelbstständigkeitIn jedem Kapitel:Einfache Erklärungen zu dem, was hinter den Bildschirmen passiertGeschichten und Szenarien aus echten ErfahrungenKlare Denkansätze für alltägliche Online-SituationenSchrittweiser Aufbau von Sicherheit und SelbstvertrauenDas perfekte Geschenk für:Jugendliche auf dem Weg in die SelbstständigkeitEltern, die ruhige und vertrauenswürdige Orientierung suchenLehrkräfte, die digitale Verantwortung fördern möchtenFamilien, die offen über das moderne Leben sprechen wollenWenn du eine Orientierung suchst, die Intelligenz respektiert, ehrlich spricht und junge Menschen dabei unterstützt, mit Vertrauen statt Angst voranzugehen, ist dieses Buch ein idealer Anfang. Gib einem Jugendlichen die Werkzeuge, um bewusst zu handeln, bessere Entscheidungen zu treffen und mit Klarheit und Zuversicht in die Zukunft zu gehen.

Deutsch | April 16, 2026 | ASIN: B0GX2TKSCR | 302 Seiten | Epub | 36.72 MB
Was wäre, wenn die Geräte, denen Sie am meisten vertrauen, genau die sind, die Sie am wenigsten verstehen?In modernen, vernetzten Umgebungen kündigt sich Risiko nicht immer laut an. Es bewegt sich leise - durch Sensoren, Kameras und Systeme, die entwickelt wurden, um das Leben einfacher zu machen, nicht unbedingt sicherer. Die Herausforderung besteht nicht nur darin, Cybersicherheit zu verstehen, sondern darin zu erkennen, wie sich diese Systeme verhalten, wenn sich etwas zu verändern beginnt.Dieses Buch führt Sie über oberflächliches Wissen hinaus und zeigt Ihnen die Realität moderner IoT- und intelligenter Systeme. Es richtet sich an Fachkräfte, die Klarheit statt Informationsrauschen suchen - an diejenigen, die verstehen müssen, was tatsächlich passiert, es schnell einordnen und souverän handeln können.Im Buch lernen Sie, wie Sie:erkennen, wie Angreifer vernetzte Geräte aufspüren und ausnutzenrealen Netzwerkverkehr analysieren und verborgene Muster sichtbar machenTransparenz in IoT-Umgebungen schaffen, ohne blinde Flecken zu hinterlassensubtile Anzeichen einer Kompromittierung frühzeitig erkennenSOC-Prozesse entwickeln, die in realen Umgebungen tatsächlich funktionierenAutomatisierung und strukturierte Reaktionen einsetzen, um Verzögerungen zu minimierenDies ist keine Theorie. Es ist ein praxisnaher, fundierter Ansatz zur Absicherung von Systemen, die sich ständig verändern - damit Sie dann die Kontrolle behalten, wenn es wirklich darauf ankommt.

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.
