A real-life social app where users broadcast ("holler") where they'll be and when — e.g. "I'm going to be at the farmer's market at 2pm" — and friends can simply show up if they feel like it. There are no invitations, no RSVP requirements, and no schedule coordination, removing the friction of organizing plans and of making or waiting for excuses. Currently iOS-only, with an Android app in development.
A collection app that bundles many standard playing card games (Solitaire, Hearts, and others) with no subscriptions or ads, including P2P online play through a simple service that connects players, plus bot opponents built from heuristics for some games and small neural nets for others.
A game framework for vibing games, which the card games app is authored in, with about a dozen game prototypes in progress on it.
A full port of Spectromancer, a game the author owns the rights to, rebuilt on the author's game framework.
An urban tree mapping platform that aggregates public tree data from city sources, with a data explorer and a new landing page being worked on for SEO. Current work focuses on data quality: vetting municipal sources and leveraging aerial photography to drive QA on tree records.
A project of the author's (pytrilogy under the trilogy-data GitHub org) that the urban tree mapping work has been used to stress test.
Warp is a declarative DSL and engine for creating music, inspired by Tidal Cycles but without the functional bits and with a stronger focus on melody and harmony.
A no-configuration instant database designed for front end developers, letting them get a database running without setup.
A simple web app that tracks the local ferry system, scans and holds ferry tickets locally on the device, and displays a large, easy-to-scan barcode for ferry workers, replacing physical ticket passes.
A coffee roasting class for home roasters that starts with open fire traditional Ethiopian styles, then shifts to covered pots, and introduces dedicated roasting machines.
A hands-on repair of the refrigerator's ice maker, using AI to help diagnose the appliance; it is the third time performing this repair.
This is a multiplayer AI music-generation party game. Players join a shared screen from their phones, submit their verses from a set of helper prompts, and hear those ideas turned into short generated rap battle performances. It also offers a non-shared-screen mode intended to be played globally with friends and strangers.
A web project at mergi.dev built as the author's response to the same pull-request review frustrations discussed in the parent comment.
This is an API that a text-based LLM can use to make paintings. Built as an experiment, it explores what an LLM chooses to paint when told to paint unprompted, reveals the weaknesses LLMs exhibit when painting, and examines how fixing those weaknesses can strip away soul and 'happy little accidents' from the resulting paintings.
A modern web app for the Analytic Hierarchy Process (AHP), a structured decision-making framework. It models a decision by organising it into a goal, criteria, and alternatives; uses pairwise comparisons to assign weights to the criteria and then the alternatives; and produces a ranking of the alternatives by preference.
A web-based todo list app implementing the Grit task management approach, based on the original grit CLI app and whitepaper. It builds a DAG of tasks where each task node can receive annotated data (traits) indicating whether the task is actionable. The author has used it daily for about a year.
This system provides real-time computer vision telemetry from cameras installed in a barn, using computer vision to monitor activity from the camera feeds.
This is a browser-based image annotation and review tool for detection and categorization tasks, built as a simplified clone of CVAT and LabelStudio, with plans to eventually expand it into an end-to-end solution.
SMS alert service for Kalshi markets that sends notifications about market movements, including upset alerts, big trades, and alerts for specific teams. Currently running a private beta with sign-up via the @OddsLineSMS handle on X.
This app is an RSS reader with social features built on AT Protocol, letting users repost and star articles, with the goal of fixing the web and countering depressive social media.
A natural language intelligence layer for contacts that lets users query their network in plain language (e.g., 'Pull everyone I know who works at a Series A healthtech in the Bay Area who also went to Stanford for undergrad') and returns either structured or unstructured results. Supports large-scale data, automatically enriches contacts with up-to-date data, delivers fast and accurate results, and integrates natively with Gmail and Google Calendar.
AuthProxy is an open source embedded integration-platform-as-a-service with an embedded connector marketplace for connecting to third-party systems and a proxy that handles credentials automatically. It has been in development for a couple of years and is currently being used to build an MCP gateway for internal tooling.
This is a markdown reader for the terminal that renders large headings via the kitty graphics protocol. It loads the file into scrollback and uses Apple Events to jump between sections instead of re-rendering, so reading feels like paging through a PDF in the terminal. It currently runs on Ghostty on macOS and may expand to other terminals supporting the kitty graphics protocol.
The AT1C Protocol is a framework that positions AI agents as inheritable entities owned by people rather than corporate assets, arguing that agents should serve humanity instead of controlling it. It frames self-ownership as a foundational principle so that fleets of agents do not become 'zombie corporations' in bankruptcy cases, under the motto 'Humans first.'
A native macOS AI-harness app that lets AI agents access a user's Apple-ecosystem data without handing them the account keys.
A native macOS app that runs each MCP server once for every client on the Mac, storing credentials in the Keychain and logging every call.
A native macOS app, soon to be released, that provides better visibility into a fleet of AI agents and offers a higher-level layer for interacting with them.
A personal Google Docs clone built to serve as the editor for the author's blog. Development drew on the author's prior Google Docs team experience via an extensive architecture-and-tradeoffs Q&A, and was implemented through five ChatGPT resets on Astra to get a feel for the model. The project is still a work in progress, with a first blog post and a project writeup planned.
A Nand2Tetris part 1 implementation carried out in Verilog, yielding an emulated computer that can run programs written in the Hack assembly language; part 2 of the course remains to be done.
Web app for playing Magic: the Gathering games locally in the browser, powered by the MTG Forge Java rules engine compiled to WebAssembly using GraalVM's new WebAssembly support.
