DeFlock is a tool to help you learn about Automated License Plate Readers (ALPRs) in your area.
I created this project after noticing the mass deployment of ALPRs in cities, towns, and even rural areas in the recent years. It's a massive threat to privacy, and this projects helps shed a light on this issue as ALPRs continue to be deployed to thousands of cities across the US and possibly beyond. Uses OpenStreetMap data to populate a map with crowdsourced locations of ALPRs, along with their type and direction they face. Provides OSM tags for easy reporting of ALPRs based on brand on OSM's editing site. Evemtually, this will be a native feature of the site.
A FOSS platform for analysing and visualizing large sets of documents. Designed with investigative journalists in mind but has other uses. Has a plugin system. Can be run as a server or locally (https://github.com/overview/overview-local). Designed to run as a docker container (bluh) but running it as-is shouldn't be difficult. Written in scala (wtf?) Seems to use postgres as its back-end.
