Why not use GeoJson for this? You can use this instead of haversine. They have prebuilt json files for states, counties, etc. Check this out for an example of geojson in action. This is using prebuilt city files. You could just map the nearby points within the boundries of county or maybe state?

Server needs to return JSON of all the points that match the search query. These points need to be parsed into a format for the server to send to the client.

To be able to calculate the distance between points, implement this... https://github.com/kristianmandrup/haversine

It should be a gem on rubygems.org. Figure out how to use it and implement a point searching function.

When a client connects before another client is processed, the connection of the first is cut without parsing the JSON. This can be replicated by

# Terminal 1
$ ruby run_server.rb

# Terminal 2
$ telnet localhost 8000 < test.json | telnet localhost 8000 < test.json

Likely via cron jobs. Check every so often which points were created more than 6 hours ago and drop them from the table if they are old.

I suspect that I don't have my rakefile implemented correctly and that it is actually doing nothing along with the migrations... If so, they can just be deleted...

The parse_json method should handle bad input gracefully
