Tools for OpenStreetMap and geospatial tasks

• osmx-rs: a Rust port of OSMExpress, a fast database file format for OpenStreetMap
• osm-cli: fetch data or subscribe to edits from OpenStreetMap
• overpass-cli: use the Overpass query language to fetch OpenStreetMap data
• shapely-cli: transform GeoJSON using Python one-liners with the help of the shapely library
• usfs-to-osm and nps-to-osm: scripts to convert official USFS and NPS datasets to an OSM-compatible schema

General-purpose CLI tools

• xpath-cli: evaluate XPath expressions on XML documents using libxml2
• ngrams: computes the frequency of sequences of characters (n-grams) in a text file
• barchart: prints barcharts in the terminal, helpful for commands that output lists of numbers
• uu: show the Unicode code points, names, categories, etc of each character in a given text
• gh-log: a log command for the gh CLI to remind you what you did last week

Web development things

• postcss-minify: a CSS minifier in 50 lines of code (it's surprisingly effective)
• remark-sectionize: wrap headings and the content that follows them in <section> elements

Miscellaneous stuff

• I made some explorables with d3 and Observable, like a satellite ground track visualizer and a map tile visibility demo
• I wrote about how to use Hobby's algorithm to make nice looking Bézier splines
