changedetection-io-osint-processor

Best and simplest tool for website change detection, web page monitoring, and website change alerts. Perfect for tracking content changes, price drops, restock alerts, and website defacement monitoring—all for free or enjoy our SaaS plan!

ci-monitoring-simulation

Calibrated simulation and detectors for MES-embedded carbon-intensity monitoring of energy anomalies in machining-style processes. Characterizes the adaptive-baseline inertia blind spot and proposes an event-anchored + residual-CUSUM detector that closes it. Reproducible: code, raw sweep data, and figure scripts.

modpack-changelogger

A powerful and customizable Python tool to generate a changelog between two Minecraft modpacks in modrinth.mrpack or curseforge.zip format.

farchive

Local content-addressed archive with locator-scoped history for opaque bytes.

idfva

This model generates investigation polygons which are used to estimate and store incremental erosion and deposition volumes along the path of a debris flow at user- defined resolution. The user will need: 1) a .LAS or .TIF of topographic change, 2) a DEM of the AOI, and 3) a shapefile (polyline) of the debris flow path of interest. Each incremental volume is georeferenced and stored within a shapefile attribute associated with a catchment area and distance from outlet for analysis.

changeos
