From first principles to practice.
Back when BitMEX paid maker rebates, I turned ~$30 into ~$2,000 by posting passive liquidity and guarding inventory. This post breaks down the rebate math, spread capture, and kill-switches—and shows how that small-edge discipline connects to “Trading Big Bags,” where structure, not bravado, determines survival.
Capital size should dictate strategy. What works for a $1,000 trader becomes reckless at $10M. The recent $17M loss on Hyperliquid shows how fragile structures — high leverage, linear contracts, and concentration — turn conviction into catastrophe. This essay breaks down why efficiency, not ego, defines survivability, and how inverse contracts, venue distribution, and leverage discipline transform outcomes.
EVs are often criticised for their manufacturing footprint, but this misses the crucial point: they have no tailpipes. In cities like London, where millions of ICE cars exhale poison daily, EVs clear the air we actually breathe. They shift emissions upstream to a few factories and power plants—sites that can be regulated and cleaned far more easily than millions of exhaust pipes. Like catalytic converters before them, EVs are not perfect, but they are a vital step in reclaiming breathable cities.
Epigenetics shows that we inherit more than DNA—we carry the echoes of our ancestors’ trauma, hunger, and resilience written into our biology. These epigenetic marks, passed across two to three generations, shape health, weight, stress, and even how we respond to the world. Yet awareness gives us agency: by confronting what we carry, we can choose healing and create a legacy of renewal for those who come after us.
Finding the cheapest ride in London isn’t as simple as picking one app. Prices fluctuate across Uber, Bolt, FreeNow, Smartzee—and even black cabs. Drawing from my time as a driver, I explore the idea of a “Ride Compass”: an app that scans all platforms, compares fares, and ensures passengers always get the best deal.
Ownership is more than paperwork. This proposal maps land titles to NFTs so the blockchain becomes the registry itself—legally recognized, programmable, and auditable—uniting code and courts for faster settlement, stronger proofs, and privacy-preserving compliance in the UK/EU.
A plastic fob once felt modern. Today, it is wasteful, clumsy, and obsolete. Digital passes stored in Apple or Google Wallets can make access smarter, safer, and more sustainable—from offices and hotels to Airbnb rentals and real estate management. The key fob solved a problem of the last century. The digital pass answers to this one.
If time is not a river or a dimension but only the distance between events, what then becomes of us? Is a life measured by years, or by the density of change it contains? This essay traces the haunting question of time—not to answer it, but to wander through its puzzles: the minus sign in the line element, the ghost of dt, antimatter’s supposed reversal, and the possibility of a physics without clocks. Time appears less as something we move through and more as something we ourselves measure—a spacing of events that refuses ever to be final.
Every year, millions of containers sail half-empty—wasting money, space, and fuel. ShipSpace reimagines global logistics as a shared marketplace, matching unused container capacity with businesses that need affordable shipping. Cheaper, fairer, greener: the future of shipping is shared.
Evil does not overwhelm the world, yet a single act of cruelty can feel larger than life—like a stain on a white shirt. Goodness is the quiet backdrop of daily life, but it gains meaning only when it resists. This essay explores the dichotomy of good and evil, the silence of the good, and the weight of responsibility that makes moral choice luminous.
