What Keeps My Brain Caffeinated!
Writing to organize, to express, and to remember my thoughts!
P.S. I like using the “—” just as much as the next AI — so if you spot one in my text, there is a good chance that it is actually me.
Radiation Principles & Modeling, Explained with a Teapot and a Dragon
A brief, non-textbook tour of thermal radiation — absorption, reflection, transmission, the radiative transfer equation, the methods people use to solve it, and why ray tracing won. With interactive figures you can play with.
Triangular Arbitrage in Cryptocurrency Trading: A Weekend Project
How a sudden imbalance across three crypto order books can be turned into a loop of trades that ends with more than it started with — and the weekend bot I built in 2015 to hunt for it: order books, the algorithm, and the implementation.
Particle–Cell Operations Optimization: Algorithm, GPU & CUDA
How we cut the cost of particle–cell coupling in a multiphysics CFD code — first by changing the algorithm, then by moving it to the GPU — and the challenges along the way.
Building a Farsi Font for MS-DOS
How a missing decent Farsi font for a FoxPro project sent a high-schooler deep into C, pointers, and interrupts: designing 8×16 glyphs on grid paper and writing a right-to-left text-rendering engine for MS-DOS.
Physics-Informed AI for ODT Simulations
Teaching Fourier neural operators the dynamics of One-Dimensional Turbulence, scenario by scenario: what should a surrogate of a stochastic simulation learn — a realization, or the statistics? With interactive results and code on GitHub.
One-Dimensional Turbulence (ODT) Model
An introduction to the ODT model: how reducing turbulence to one dimension with stochastic triplet maps makes high-fidelity simulation affordable, and where the model is used, from combustion to atmospheric flows.
