Support Engineering is where theory collides with reality, where a beautifully designed API meets a customer who can't get it to work, and where the gap between what was promised and what is working gets closed, one ticket at a time. This book gives you everything you need to go beyond the ticket and become a complete support engineer.

Qi — TeaserThere is a moment that happens reliably around the fifth small infusion of a well-stored aged sheng pu'erh. Your shoulders drop. Your jaw unclenches. The internal weather of the morning settles into something quieter. You are not drowsy. You are not "buzzed." You are present in a particular way that coffee has never produced.The folk vocabulary calls this cha qi (茶氣) — "tea energy."This book takes that subjective report seriously enough to take it apart.What if Qi is real — and measurable?Most books about tea pick a side.They are either romantic — the kettle, the clay, the lineage, the master — and leave the science out.Or they are reductionist — caffeine in milligrams, antioxidants in ORAC units — and leave the experience out.Neither is honest.Qi does the harder thing: it keeps the felt experience and explains it, citation by citation, without flinching.Inside the cup, you will find:Dopamine prediction errors firing on every small infusion — why Gongfu Cha is structurally well-fitted to how attention actually works.L-theanine + caffeine as a two-molecule attention circuit, with EEG data to prove it.Theabrownins — the dark, oxidised pseudo-fiber in aged Pu'erh — feeding the gut bacteria that upregulate TPH1, the enzyme that makes ~90% of your body's serotonin.Eurotium cristatum — the "golden flower" fungus crawling through baskets of Fu Cha and Liu Bao, and what it does to your vagus nerve.Water — 98–99% of the cup by mass, and the variable nobody optimises.Sheng, Shu, Liu Bao, Fu Cha, Anhua — five different microbial assemblages, five different molecular fingerprints, five different physiological modes. Not interchangeable.The ceremony cultures of China, Japan, and Korea — treated as historical objects with dates, not timeless mysticism.The recursive cup — why a retuned drinker pulls more out of the next infusion than the last.A nerd's field guide30 short chapters. Each one built around a small number of testable claims. Every claim traceable to a peer-reviewed paper, mostly indexed in PubMed/PMC. Every metaphor paired with a mechanism. Every "Qi" sensation matched, where the literature allows, to a specific molecule or neural circuit.Where the literature does not yet allow it, the book says so — plainly — instead of papering the gap with mysticism.The opinionated thesisAttention is the active ingredient. Not the chemistry.The gut is doing more for your mood than your prefrontal cortex.The nicest thing you can do for your brain in the morning is small cups of old leaves and silence.If that sounds like your kind of nerdy — read on.The cup is a small machine. This book is its manual.

In a world of infinite AI-generated text, fluency is no longer a credential—trust is. Learn how to engineer "signal" into your technical writing and build an authoritative presence that algorithms can't replicate. This is the definitive practitioner’s guide for publishing in the AI era.

When his nosy neighbors mock his basement lab, Chunmun Singh doesn’t argue — he clones their newborns and leaves the duplicates on their doormats with a fire alarm serenade.What follows is pure chaotic comedy as panicked husbands face identical babies while their wives spin wild Kali Yuga myths to explain the miracle.A sharp, sensory-rich satire on high-density living, workplace grudges, and the sweet taste of petty genetic revenge.

In the delicate intersection of poetry and Zen, there exists a quiet world where words dissolve into silence, and silence speaks louder than any verse. This is a world where mountains breathe, rivers hum, and the human heart, in its fleeting moments, touches the eternal. Chinese culture, with its profound literary and spiritual heritage, has long nurtured this union, allowing poets to meditate with words and Zen masters to awaken through imagery.The Poetic Mind: Zen and Philosophy is an invitation: to wander through bamboo groves and misty valleys, to listen to the whisper of wind and water, and to encounter the subtle truths hidden in the simplest moments. Here, poems are not merely read—they are lived; Zen is not merely studied—it is experienced.This book seeks to be both a guide and a companion. Step by step, chapter by chapter, it leads the reader from emptiness to presence, from solitude to harmony, from contemplation to awakening. It is a journey where classical wisdom meets modern life, where aesthetic delight walks hand in hand with mindful awareness, and where every page offers a chance to cultivate a poetic Zen mind.

Coherent Mathematics (CoMath) — Mathematics That Earns Its StructureWhat if mathematics did not precede physics — but emerged from it?Conventional mathematics assumes its foundations: sets, numbers, operations. Coherent Mathematics (CoMath) assumes only one thing: coherence is not given. Coherence is what survives.From this single axiom, CoMath reconstructs the mathematical universe bottom-up. Numbers, geometry, iteration, and the exponential structure are not postulated — they are derived. The constants of nature are not inserted — they follow. The chain is complete:Geometry → Iteration → Planck Scale → Constants → Time → Schrödinger → Quantum MechanicsZero free parameters. No circular reasoning. No unjustified axioms.CoMath V4 presents:A rigorous axiomatic foundation built on coherence as the sole primitiveDerivation of π, φ, e, ln, and exp from pure iteration structureThe Planck-to-electron mass ratio m_P/m_e from geometry aloneA new perspective on Riemann, Hodge, and the foundations of formal mathematicsDeveloped in direct collaboration between human intuition and AI formalizationThis is not mathematics applied to physics. This is mathematics derived from the structure of reality. "Real science begins with a thought, not an equation." — Jens Deutschmann

Stop treating Android like a black box and start thinking like the engineers who build it.

Most books about ChatGPT explain the magic. This one shows you the math. Inside Large Language Models, Volume I takes a curious beginner from "what is an LLM" to a complete, trained GPT, with nothing more than high-school algebra, a working laptop, and a willingness to read carefully. Every formula is walked through by hand. Every line of code comes with a plain-English explanation. By the end you will have built, trained, and run your own transformer from scratch, and you will know exactly what is happening inside. No PhD or Data Science required. No prior machine learning needed. Just curiosity and a calculator.

Fractal Uncertainty Theory (FUT) — A New Foundation of PhysicsSunflower, quasicrystal, spiral galaxy, cosmic web — they all do the same thing.What if quantum mechanics, gravitation, the fundamental constants, and the large-scale structure of the universe all follow a single principle? Not as a metaphor — but mathematically derivable, with zero free parameters?Fractal Uncertainty Theory (FUT) constructs physics from two primitive operations: Rotation (ℛ) and Recursion (ℱ). From their interference emerge π and φ, the four forces as a unified spectrum, the fine-structure constant α = 1/137, the Planck scale, the Schrödinger equation — and six resolved Millennium Problems.FUT V9 presents across 478 pages and 35 chapters:Derivation of fundamental constants from pure geometry (zero free parameters)Dark energy and dark matter as consequences of the Void Exponential Feedback mechanismThree spatial dimensions + time from icosahedral A₅ symmetryThe Higgs-centered particle structure as a periodic systemRigorously documented progress on Riemann, Yang-Mills, Hodge, P≠NP, and beyondNo speculative model. No retroactively fitted constants. A theory that begins with a thought — and ends with testable predictions.
