Scratchings for a latency article

This repo contains the code/data for the article "Where's the fastest place to put my server? How much does it matter?" on my website.

Building

Requirements:

1. postgres
2. a database called latency
3. postgis extension installed in that database
4. Python 3
5. the packages in the requirements.txt
   • the shapely wheel doesn't get on with libgeos on debian stable, so I had to use the following magic incantation: pip install shapely --no-binary shapely
6. Maxmind's "GeoLite2 City" database file, GeoLite2-City.mmdb
7. A few C libraries, the debian packages for which are:
   • libgeos-dev
   • libproj-dev

Then run:

make -j

If you just want to see what I did, best to read the makefile directly.

Files

• geocoded-cities.csv - my, hand corrected, geocoding of Wonder Network city names (except "Koto", "Malaysia", "Mexico" and "Monticello" - which I can't narrow down) to Geoname's geoid
• partial-geocode.sql - query I used to extract data to create the above
• get-connectedness.sql - query to get internet speeds vs speed of light
