Who’s On First Browser (v2)

go-whosonfirst-browser is a web application written in the Go programming language for rendering known Who’s On First (WOF) IDs in a number of formats including HTML, SVG, PNG and GeoJSON. It uses Bootstrap for HTML layouts and Leaflet, Tangram.js and Nextzen vector tiles for rendering maps. All of these dependencies are bundled with the tool and served locally. With the exception of the vector tiles (which can be cached) and a configurable data source there are no external dependencies. It is designed to work locally and remotely with a variety of Who’s On First datasources.

The Why of the How

One of the things I’ve taken to saying in recent years is that sometimes we make mistakes because of circumstance and sometimes we make bad decisions because of reasons… so please just write those reasons down somewhere.

WOF in a Box (part 3)

The Spelunker was rebuilt on a bare Ubuntu 16.04 Linux server, following Dan’s WOF in a Box instructions and everything worked without a hitch. Along the way, I made some updates to the “fetching and indexing data” piece specifically to make things faster and easier for people who just want to work with the data as-is and don’t need to make updates.

Privatezen

The first week I started at Mapzen, in 2015, I remembering thinking I wonder if I can swap out each one of third-party services used by Privatesquare with an equivalent Mapzen service? The answer, at the time, was “No”. It was a useful reminder of the work we had set out for ourselves.

Who’s On First, Chapter Two

It means that while things are not literally “better than yesterday” – since yesterday you didn’t have to read this blog post – it means that things are hopefully better than the yesterday of the last time a service you came to depend on had to shutter its doors.
