Glasscn

A glassmorphism/Apple-inspired shadcn registry of React components that ports native Apple UI components and paradigms to the web. It also ships native components that integrate with React Native / Expo, enabling apps with nearly the same look and feel across all platforms. It can be used by pasting the URL into an AI agent to build an app.

dia (do it all) programming language

A batteries-included programming language with Rust-inspired syntax and type features and arena-based memory safety that avoids Rust-style lifetime parameters. It transpiles to C so it compiles anywhere C runs, offers a native JSX-like syntax (DSX) usable for any function with the right signature, incremental compilation with hot module reload (HMR), and effortless C interop via a bundled clang compiler (occasionally needing a short manifest to map memory safety). The standard library includes a cross-platform GUI toolkit with a prosemirror-like WYSIWYG text editor, and modular pieces such as text rendering, the event/input system, and a signals-based reactive library that can be reused independently in other contexts. Not yet open-sourced, pending base feature stability.

Virtual Diwali

A browser-based casual game and experience about Indian festivals where players walk through an old neighbourhood down to a river, light 108 oil lamps, set off crackers, and send lanterns into a sky shared by everyone. Includes a lamp that keeps burning per Indian tradition, a rooftop garden that keeps growing, and more missions planned, running without login or ads.

New Rust compiler built from scratch

A brand new Rust compiler being built from scratch with the goal of radically improving Rust compile times, applying the same approach used to create agent-built C++ compilers that compile about 4x faster than GCC and Clang. The compiler is not yet at the self-hosting stage, but early results are promising.

cppgm-extended

A C++ compiler built by teaching AI agents to write C++ compilers from scratch. After iterating on many agent-built versions, the resulting compiler compiles about 4x faster than GCC and Clang. The build process is documented in a blog series, and the project inspired the author's new Rust compiler effort.

etoku

Language-learning platform for Japanese that builds study cards from native content (TV, movies, books) the learner chooses; each card is a sentence with one unknown word or grammar point, with audio and a screenshot. Nothing is AI generated — content is taken from real native material, with a sentence analyzer that breaks sentences down into the concepts needed to understand them.

bopbop

A Chrome extension that lets Claude Code, Codex, or other agents control the user's browser, with a skill/MCP connector to link the agents to it. Built to do the same browsing tasks as browser agents faster and with fewer tokens.

Novalede

This app is an MCP-connected newspaper that turns newsletters and email into articles with the key point front and centre, so the gist of whether a message matters is immediately clear. It also picks Hacker News articles of interest and summarizes what the comments say, removing sensationalism from reactions.

Rank

Rank is a programming language designed to be comfortably written on a phone, combining ideas from BASIC and APL with array operations, words instead of special symbols, and data-first function calls. Its creator is also considering a dedicated handheld device with a physical QWERTY keyboard and multi-function keys like the ZX Spectrum had.

Exhibit

A personal apps platform where an AI agent builds small apps for users, their friends, and family, which can be run on the platform or downloaded for portability with no lock-in. It enforces a deny-by-default security policy to contain untrusted AI-generated code, and is adding API connectors to bring in user data, with self-hosting supported today and a hosted version in progress.
