hazard-alerter

A daily weather-hazard forecast, triggered from your phone.

  • A GitHub Actions workflow (daily_forecast.yml) that runs on demand via workflow_dispatch.
  • Triggered by an Apple Shortcut that grabs the phone's current location, extracts the ZIP code, and posts the dispatch with that ZIP as an input.

boring-log-app

An open-source field app for geotechnical boring logs.

  • Handles soil boring logs, bedrock/rock core logs, and well logs, with built-in soil classification aligned to EPA / state DEP / USGS standards.
  • Ships the full symbology library rather than a curated subset, reusing existing agency symbol assets as-is.
  • Starting with NJDEP's jurisdiction-specific symbols (well-construction, environmental), with other states to follow.
  • Offline-first for field data collection, with an office mode; a Rust/C core via FFI handles performance-critical pieces like USCS classification and DIGGS/AGS parsing, with Python on the server side for heavy validation and reporting.
  • Data model built first: a Postgres schema shaped to map onto the DIGGS standard.

coral-sea-dee2020

Reproducing a coral-based superposed epoch analysis from a 2020 Science paper on volcanic eruptions and ENSO.

  • Three parallel implementations — the original MATLAB reference, plus Python and R ports — of the Superposed Epoch Analysis (SEA) from Dee et al. 2020.
  • Tests whether El Niño-like responses follow major tropical volcanic eruptions, using the Palmyra coral δ18O record.
  • Cross-validated across all three languages to 4 decimal places, byte-verified against the paper's official supplementary materials.
  • Finding: the composite stays inside the 95% confidence band at every post-eruption lag — no statistically significant response detected.
