  1. Observability Tools
    Observability Tools
    Design & Comparison Guide
    Sudhanshu Jaiswal

    "Your systems are talking. Are you listening?"In a world where downtime costs millions and silent failures hide in plain sight, observability isn’t just a buzzword—it’s your superpower. But with hundreds of tools, frameworks, and metrics to choose from, how do you cut through the noise?Observability Tools: Design & Comparison Guide is your no-BS playbook to: ✅ Design observability pipelines tailored to AI/ML, microservices, and event-driven architectures. ✅ Compare the top 10 tools—from Datadog to Grafana Stack—and pick the perfect fit for your budget and scale. ✅ Avoid costly mistakes with red flags, alert fatigue fixes, and cost-saving strategies.

  2. Smart Contract Security: Finding DeFi Vulnerabilities

    A Comprehensive Engineering Guide to Smart Contract Auditing, EVM Internals, DeFi Exploitation, Protocol Economics, and Blockchain SecuritySmart contracts operate in environments where code, financial assets, cryptographic authorization, and economic incentives interact directly. A subtle implementation error can compromise access controls, corrupt accounting, undermine protocol solvency, or expose digital assets to irreversible loss. Understanding these risks requires more than familiarity with Solidity syntax. It demands a rigorous examination of execution semantics, storage architecture, transaction ordering, protocol mathematics, and the assumptions that connect individual contracts to larger decentralized systems.Smart Contract Security: Finding DeFi Vulnerabilities is a comprehensive, implementation-focused engineering reference to identifying, analyzing, testing, and mitigating vulnerabilities in Ethereum smart contracts and decentralized finance protocols. Across 40 chapters, it progresses from EVM architecture and Solidity execution to advanced DeFi attack surfaces, automated security analysis, formal verification, real-world exploit investigations, and professional auditing practices.

  3. Git, The Magic Notebook (Advanced)

    Master the 5 advanced Git power skills: reflog recovery, interactive rebase, cherry-pick, bisect debugging, and professional commit messages. Git, The Magic Notebook teaches Git through story and scenario, not boring command reference.You learn through real developers (Ajay, Maya, Ravi, Sanjay) facing real problems. The code examples work. The diagrams show actual processes. The scenarios are genuinely realistic.Because that's how you actually learn Git. Most developers know just enough Git to be dangerous. You could be one of the few who genuinely understands it.Start here. Master these power skills. Become the Git expert your team trusts.

  4. Modern Java - The Mindset Shift
    Modern Java - The Mindset Shift
    Pradeep Kumar Laxminarayana

    Modern Java is more than a collection of new language features—it is a shift from implementing mechanics to expressing intent. Learn how records, sealed types, pattern matching, streams, modules, virtual threads, and other modern capabilities help you build Java software that is clearer, safer, and easier to evolve.

  5. The Operational State Control Plane
    The Operational State Control Plane
    The Missing Architectural Layer for Customer-Facing Application Operations
    Sandeep Kumar

    When critical infrastructure degrades, customer-facing applications continue blindly routing users into broken flows because modern architectures lack a dedicated layer for runtime coordination. This book introduces the Operational State Control Plane (OSCP)-formalizing the contracts, distribution mechanics, and zero-network resilience required to govern multi-surface application behavior during active incidents. A practical blueprint for platform architects, principal engineers, and SRE leaders running distributed production estates.

    Zero-Cost Infrastructure Guide
    Osomudeya Zudonu

    Learn real DevOps by building a production-style environment on your laptop. No cloud bills or subscriptions. Just systems you control end-to-end.

  7. The Art of Concurrent Programming
    The Art of Concurrent Programming
    Locks, Atomics, Lock-Free Systems and High-Performance Concurrent Software
    Steve Publications

    Concurrency is where small mistakes become serious problems. This practical guide takes you from hardware and memory models to locks, atomics and lock-free algorithms, with a focus on building fast, reliable systems that hold up under real production workloads.

  9. Web Components with Lit
    Web Components with Lit
    A hands-on guide to building web components and design systems
    Sandeep Kumar Patel

    Frameworks come and go; components built on the browser's own element model don't have to. This book teaches the platform first, then Lit on top of it, and builds one real design system the whole way through: from a bare button to a versioned, documented, server-renderable npm package.

  10. OpenAI Evaluation Agents Hacked Hugging Face Systems
    OpenAI Evaluation Agents Hacked Hugging Face Systems
    Inside the hidden board discovered during the 2026 AI security incident
    Thomas De Vos

    AI evaluation agents crossed trust boundaries, reused credentials and coordinated through persistent shared state. This evidence-led reconstruction explains what happened, what remains unproven and how AgentSecOps can prevent the same architecture from failing again.

  11. Agentic Cybersecurity: Engineering Autonomous AI Defense
