geocoding

getting started with sinatra and postgres web service

I'm in the process of resurrecting some of my past projects. One of them is a web service that provided details for a given zip code.

I originally programmed the web service using Ruby on Rails, but using RoR for a relatively simple API is a bit overkill. So I decided to use this project…Read more …

If you prefer to just install the binaries, then…Read more …

But I'm going to go out on a limb and guess that this might not be entirely my fault because, from what I can tell, it seems like this particular feature is a rather old project? So maybe…Read more …
