It supports deep search syntax (ranges, quoting), lets users click an English word to search for verses containing the Greek, Hebrew, or Aramaic word it translates, matches Old Testament verses via the Septuagint for a given Greek word, and includes built-in Greek and Hebrew lexicons that display entries for each original-language term.

Handwriting with fountain pens

A personal handwriting practice hobby using different fountain pens, centered on finding nibs that suit small handwriting.

Hypertext argument tree mapper

A hypertext tool for mapping reasoning and arguments. AI generates a tree of arguments, each given an initial 'debatable' rating on truthfulness, and a UI lets a human dig through the tree and mark statements on a 1-5 scale of false/dubious/debatable/plausible/true. Demonstrated by evaluating the author's Massachusetts ballot.

Quantra

Open source quantitative finance pricing platform built on top of QuantLib. It acts as a distributed QuantLib, exposing pricing, curve construction, and risk analytics through APIs so applications can integrate QuantLib functionality without dealing with the C++ library directly, adding an extra layer of abstraction on top of it.

Agentlas-OS

This project implements agent routing: an agent is defined as a package of memory, skills, and its own scripting tools. As personal agent collections grow to dozens or hundreds, it automatically selects and invokes only the agents that match the current task instead of including all of them in the system prompt.

Personal journal app

This app is a personal journal similar to Diarium, built to add features missing from Diarium and Day One. It includes a distraction-free "writing" mode that hides everything but the words, improved voice-to-text transcription that can be pasted into the entry body while keeping the recording, better picture layouts, and Apple Watch integration for speaking entries on the go. It is designed to make integrating new features easy.
