   How I Read A Pull Request

   A systematic approach to reviewing pull requests using the journalist's 5 Ws and H framework. The process covers when to review (start of day, between meetings, after submitting your own PR), what to look for based on PR intent, understanding your motivation as a reviewer, considering the author and audience, and a specific reading order: title/description first, then tests (test-driven review), followed by implementation alphabetically, and finally a big-picture pass to verify goals and overall structure.

   Ruby Can Draw Cities Now

   A developer built two open-source Ruby libraries (ruby-libgd and libgd-gis) that enable pure-Ruby GIS rendering without external dependencies like PostGIS or Mapbox. The system loads GeoJSON data, applies Mercator projection, and rasterizes it to PNG using native GD graphics bindings. Successfully tested by rendering Paris, Tokyo, New York, and Paraná with real OpenStreetMap data, it enables scriptable map generation for Rails apps, PDFs, reports, and static sites—opening new possibilities for civic tech, urban planning, journalism, and data science workflows.
