Cheng Lou

A zero-annotation static analysis engine for catching NaN, division by zero, and layout bugs before they ship.

A tiny Bash toolkit shows how Claude Code’s hook layer can override rigid permissions, repair dontAsk mode, and make safety decisions from live context.

A JavaScript and TypeScript engine that measures text once, then reuses cached widths to wrap and size it without leaning on the DOM every time.

How a two-phase architecture severed text measurement from the browser's synchronous layout cycle, unlocking high-performance typography for custom renderers.

A compact Modal scaffold for PyTorch that treats checkpoints, preemption, and `torch.compile` edge cases as first-class problems instead of afterthoughts.

By rendering to a single hidden framebuffer and transferring pixels to standard 2D canvases, Chenglou's zero-dependency playground bypasses a hard browser constraint.

How Cheng Lou’s experimental toolkit abandons declarative state for continuous physics, treating the browser like a low-level rendering target.

How a four-layer Transformer uses test-time compute scaling and 2D spatial embeddings to solve extreme Sudoku without learning the rules.

How a frontend pioneer stripped Denoising Diffusion Probabilistic Models down to a single PyTorch file.

How a pure TypeScript library bypasses the DOM to measure and wrap text 500 times faster.

How Cheng Lou turned the browser's layout engine into a GPU, bypassed GitHub's Markdown filters, and built a zero-JavaScript shader using pure CSS.

How a brilliant solution to React's stale closure problem became a cautionary tale about fighting the browser's event loop.

How a React pioneer built a digit classifier without neural networks, backpropagation, or a single machine learning dependency.

How a pure-TypeScript engine bypasses the DOM to turn multi-line text measurement into a blazing-fast math problem.
