Writing about what I build

A living reference for writing posts — thumbnails, code, tables, alerts, footnotes, images, audio, video, and YouTube embeds.

How Ken Perlin's gradient noise creates infinite terrain, clouds, and fire — and why Simplex improved it thirty years later.

A frontend engineer's guide to the architecture behind GPT — self-attention, positional encoding, and the encoder-decoder split.

Render infinite geometry on a fullscreen triangle — SDFs, sphere tracing, and the shader loop that replaced polygon soup.

How to ship a markdown blog with zero database, full SEO, and static export — the same stack powering mahdi.is-a.dev.

Loss surfaces, learning rates, momentum, and Adam — the optimization loop that makes neural networks actually learn.

Lessons from building NPUI — tokens, primitives, and the gap between Figma and production.

How React 18 schedules updates, keeps the UI responsive during heavy renders, and what useTransition actually buys you.

The data structure behind PostgreSQL, SQLite, and MySQL indexes — balanced trees, page alignment, and why O(log n) isn't enough.

From Figma's design engine to Cloudflare Workers — why WASM is becoming the portable bytecode layer of the web stack.

How distributed systems agree on a log when nodes fail — terms, heartbeats, and why Paxos stayed in papers while Raft got textbooks.

Why implicit flow died, how PKCE protects public clients, and the token flow every React app should implement.

Git isn't a filesystem with history — it's a content-addressed object database with labels. Once you see the DAG, everything clicks.

Building Analytick taught me that you can have real-time dashboards and respect user privacy — if you design constraints in from day one.
