Test site that will be used to inform an internal database. Looking to use Rails, Postgres and Elasticsearch. One data object called "Stores" (name, address, city, state, lat, lng). Goal is to use Elasticsearch as the "GET" engine here because the eventual data set will be large and we're looking to use Elasticsearch on other areas of applications as well. After having basic syncing between the database (Postgres) and the search (Elasticsearch) in place and updating each time an object is created, updated, or deleted in Rails, the app should have an example of each of these things 1.) Get X closest places to a given lat/lng input 2.) Get all places within X meters of lat/lng 3.) Get all places within polygon bounding box It's expected that the repo will be shared privately upon completion and a short amount of time (hour max) to ensure it's set up and running properly on our local machines (macbook running 10.10) Upon successful completion, there is a lot more rails/elastic search work needed, this is more or less a test project that will serve to quicken dev time for this first app and also be a starter project for what will be a lot more.

This could be “set the Fuel Tank Pressure to 5 Bar” coded in ruby. So when the event is executed in the sequencer the sequencer calls a method in the tank object that sets the pressure to 5 Bar. 5)When the engine simulation is running the sequencer shall automatically regulate the tank and chamber pressures down by 10% per time tick 6)There is a 10% uncertainty to the regulation of the tank pressures, and you have to implement this in the ruby program. 7)If the pressure difference between the two tanks are more than 10% of the tank pressure, during a 3 seconds period the engine will explode. 8)The simulator must monitor the pressure in the tanks and display an alert the user to abort simulation if a fault arises. 9)It shall be possible to press a key on the keyboard causing the simulation to stop at any point without loosing data collected until that point. ...
