narro can now generate audio narration for Hugo blog posts, with synchronized sentence highlighting in the browser. The alignment problem turned out to be more interesting than expected.
A walkthrough of Chartfold, a Python tool that loads your medical records into SQLite and exposes them to Claude via MCP for structured analysis, visit prep, and ad-hoc queries.
The problem isn't too much code. It's code without purpose.
A retrospective on three years of building R packages and writing papers for masked series system reliability, and what comes next.
dapple is a terminal graphics library with one Canvas API, seven pluggable renderers, and eleven CLI tools for displaying images, data, video, math, and more.
A walkthrough of Posthumous, a self-hosted dead man's switch that monitors periodic check-ins via TOTP, progresses through escalating alert stages, and triggers automated actions if you stop responding.
A guided tour through my open-source ecosystem: encrypted search theory, statistical reliability, Unix-philosophy CLI tools, AI research, and speculative fiction. How the projects connect and where to start.
Observation functors in maskedcauses: composable functions that separate the data-generating process from the observation mechanism, enabling mixed-censoring simulation and verified Monte Carlo studies.
pagevault turns any file into a self-contained encrypted HTML page. No backend, no JavaScript libraries, no external dependencies. Just AES-256-GCM and the browser's built-in Web Crypto API. The interesting part is making it work at scale.
The maskedcauses R package for MLE in series systems with masked component failures, built on composable likelihood contributions and validated through simulation.
AlgoGraph is an immutable graph library for Python with pipe-based transformers, declarative selectors, and lazy views.
A database-first bookmark manager with hierarchical tags, content caching, and NLP auto-tagging. Part of the Long Echo toolkit.
A tool that converts source code repositories into structured, context-window-optimized Markdown for LLMs, with intelligent summarization and importance scoring.
A C++20 sparse spatial hash grid for N-dimensional spatial indexing with O(1) insertions, O(k) neighbor queries, and 60,000x memory reduction over dense grids.
EBK is a comprehensive eBook metadata management tool with AI-powered enrichment, semantic search, and knowledge graphs. Part of the Long Echo toolkit.
A virtual POSIX-compliant filesystem using content-addressable DAG storage with SHA256 deduplication.
An immutable-by-default tree library for Python with composable transformations, pipe-based pipelines, and pattern-matching selectors.
A C++ library for composable hash functions using algebraic structure over XOR, with template metaprogramming.
A generic R framework for composable likelihood models. Likelihoods are first-class objects that compose through independent contributions.
An R package that gives hypothesis tests a consistent interface. Every test returns the same structure. You can write generic code that works across all of them.
An R package for specifying hazard functions directly instead of picking from a catalog of named distributions. You write the hazard. It handles the rest.
An R package that treats MLEs as algebraic objects. They carry Fisher information, compose through independent likelihoods, and propagate uncertainty correctly.
An R package that treats probability distributions as algebraic objects. They compose through standard operations. The algebra preserves distributional structure.
