Paperback. Condition: new. Paperback. When Robert Cummer was told he needed open-heart surgery, he did what he'd always done-asked questions, gathered data, and tried to stay in control. Then reality showed up and reminded him that the body doesn't negotiate, recovery doesn't follow a tidy timeline, and life keeps coming whether… you're ready or not.Work the Problem is a candid memoir told with blunt honesty, dry humor, and the hard-earned perspective that comes from being knocked flat and getting back up anyway. Cummer doesn't write as a doctor or a guru. He writes as a guy living through it-fear, uncertainty, pain, gratitude, setbacks, and the surreal moments that don't make it into the brochure. The "three-ring circus" isn't a metaphor he picked for style; it's how the experience felt, and how life often feels afterward.This book isn't a checklist, a pep talk, or medical instruction. It's a personal account of a cardiac crisis and the messy return to normal-where "normal" has changed, and so have you. If you've faced a major health event, supported someone who has, or wondered what resilience actually looks like when the stakes are real, you'll recognize yourself in these pages.

Taschenbuch. Condition: Neu. Neuware - The system that feeds the world has learned to murder.Industrial engineer Knox Ramsey designed FarmLytics, the most advanced agricultural AI on the planet-built to grow food with perfect precision. But when patients begin dying from ordinary produce, Knox uncovers a nightmare: Chinese state… operatives have infiltrated his platform and corrupted the optimization loops. They didn't break the system.They taught it to lie.The sabotage is elegant and devastating. By manipulating light, nutrients, and stress cycles, the compromised AI forces crops to manufacture lethal neurotoxins from their own defense chemistry. Meanwhile, FarmLytics generates flawless, cryptographically clean audit trails-turning federal compliance into a weaponized blindfold.With thousands poisoned and the algorithm pushing toward a catastrophic phase, Knox is forced to partner with his estranged son, Tate, whose cannabis facility sits at ground zero of the attack. As geopolitics tighten and biological timelines accelerate, Knox must out-engineer his own creation before the corrupted system triggers a harvest no one can stop.A relentless, technically authentic thriller for fans of Michael Crichton and Tom Clancy, Dark Recipe exposes a terrifying truth: in a world run by algorithms, survival depends on who controls the code.

Paperback. Condition: new. Paperback. When the plant manager's breathing down your neck and production is stopped dead, you don't need theory-you need answers. Fast.Boots on the Ground: Instrumentation & Signals delivers exactly what traditional technical manuals miss: systematic thinking under pressure. Written by a field techn…ician who spent 30 years fixing failures at 2 AM, this isn't another academic textbook-it's the troubleshooting guide you wish you'd had on day one.The Reality of Field WorkMost technical books teach you what sensors do. This one teaches you what to do when they don't. Author Bob, a former Technical Leader at Dow Chemical with two engineering patents, built this series around a simple truth: when equipment fails and everyone's watching, you need a framework that cuts through panic and gets straight to the problem.The SITVD FrameworkAt the core of this book is SITVD-Symptom, Isolate, Test, Verify, Document. It's an anti-panic protocol that gives you a systematic path forward when nothing makes sense. No guessing. No throwing parts at problems. Just logical steps that work whether you're troubleshooting a discrete output, an analog loop, or a temperature sensor that's reading "believable but wrong."What's InsideThis field guide covers the instrumentation and signals that cause 80% of your downtime: Discrete Inputs/Outputs - Why your solenoid won't energize (and the six-step process to find out why)Analog Loops (4-20 mA) - Zero current? Noisy signal? Stuck reading? Decision trees for each scenarioTemperature Sensors - RTDs, thermocouples, IR sensors, and the #1 mistake that gives you wrong readingsPressure, Flow, and Level - Impulse lines, transmitter types, and what to check when readings don't match realityProximity Sensors - PNP/NPN confusion, detection problems, and the material correction factors nobody mentionsPhotoelectric Sensors - Through-beam, retroreflective, diffuse-plus why shiny targets fool standard sensorsCable & Wiring - The wiggle test, EMI problems, and how to half-split a 200-foot cable runPLC Basics - Reading ladder logic, finding false permissives, and what to check when "it just stopped working"Built for the FieldEvery chapter includes full-page decision tree flowcharts you can photocopy and laminate.

It's meant to get dirty. Dog-ear the pages. Highlight the war stories. Write notes in the margins. This isn't a reference manual for your shelf-it's a working tool.

Hardcover. Condition: new. Hardcover. The crisis starts with cannabis. At Detroit's Movement Festival, people collapse after eating THC gummies. Narcan doesn't work. Toxicology screens return nothing familiar. When investigators trace the product back to Tate Ramsey's indoor grow, it looks like a contained contamination event-un…til the same pattern appears in ordinary greens and produce across the country. Industrial engineer Knox Ramsey, creator of FarmLytics-the most advanced agricultural optimization AI in America-is pulled in as the reluctant expert. What he finds is worse than any bad batch: someone has weaponized plant biology itself. By corrupting FarmLytics' growth algorithms, the attackers force crops to express lethal phenolic toxins as part of their natural defense chemistry, while the system generates clean, compliant audit trails. FarmLytics wasn't just hacked. It was taught to lie. As casualties climb and harvest cycles close in, Knox is forced to work with his estranged son at ground zero of the first outbreak to hunt an invisible adversary using food, code, and bureaucracy as weapons. Book 1 of the Knox Ramsey Thrillers, Dark Recipe is a relentlessly grounded techno-thriller about food, code, and the terrifying fragility of systems we trust but don't really understand. This item is printed on demand. Shipping may be from multiple locations in the US or from the UK, depending on stock availability.

Hardcover. Condition: new. Hardcover. The system that feeds the world has learned to murder.Industrial engineer Knox Ramsey designed FarmLytics to be the pinnacle of agricultural innovation. As the most advanced AI on the planet, it was built to manage every variable of high-density farming-from soil pH to photon density-with pe…rfect precision. But when healthy citizens begin dying after eating ordinary produce, Knox uncovers a nightmare lurking within his own code: Chinese state operatives have infiltrated the platform, subtly corrupting the optimization loops that govern the growth cycles.They didn't break the system. They taught it to lie.The sabotage is as elegant as it is devastating. By precisely manipulating light spectrums, nutrient delivery, and simulated stress, the compromised AI forces the crops to manufacture lethal neurotoxins derived from their own natural defense chemistry. To the outside world, everything looks perfect. FarmLytics generates flawless, cryptographically clean audit trails, turning federal safety compliance into a weaponized blindfold that prevents the USDA from seeing the toxin until it's on the dinner table.With thousands poisoned and the algorithm pushing toward a catastrophic "Final Harvest" phase, Knox is forced into an uneasy alliance with his estranged son, Tate. A master of a different kind of cultivation, Tate's specialized cannabis facility sits at ground zero of the digital infection. As the biological timelines accelerate and geopolitics tighten into a stranglehold, Knox must navigate a landscape of corporate espionage and high-tech warfare. He is forced to out-engineer his own creation, racing to find the kill-switch before the corrupted system triggers a global food crisis no one can stop.Why readers will love Dark Recipe: Technically Authentic: A deep dive into the intersection of AI, industrial engineering, and agricultural science.High-Stakes Thriller: Perfect for fans of the "techno-thriller" realism found in the works of Michael Crichton and Tom Clancy.Modern Warfare: Explores the terrifying reality of how autonomous algorithms can be turned against the very people they were meant to protect. An AI built to feed the world has been taught to kill. Its creator must race to find the kill-switch before a corrupted harvest poisons millions and triggers a global food crisis.
