I have a little example application which I need to deploy on a PaaS environment (Google App Engine or Open Shift). I would prefer Google App Engine as provider because it is much easier to work with it than with OpenShift. But the application uses JEE 7 and CDI, which both seem not to be supported out-of-the-box by Google App Engine. So we have OpenShift as alternative which has support for JEE 7, but is more difficult for users to setup. Your tasks are: ? Check if it is possible to make the application running on App Engine with no more extra effort than for OpenShift. The application must run with the free plan of the provider. (Alternatively, you can suggest any other provider, only it must have free registration without any expiration and the application must be run for free. Please ask me before if you have any other suggestion than GAE or OpenShift.) ? If there is no more effort, select App Engine as PaaS provider. Else select OpenShift. ? Configure the application to run on th...

We have a web server that hosts a database with the latest Great Britain OSM street map data. The server is Ubuntu Linux 14.04.1 running Apache and we use PostgreSQL Databases of osmgb (OSM data) and PostGIS. We need a web service that accepts an array of either UK Postcodes (e.g. "GU4 7EQ") or latitude and longitude coordinates (e.g. "51.2538621,-0.5277378") and calculates a route between them. The web service should be able to return the following information in JSON format: - Route (e.g. text showing turn-by-turn directions) - Polyline coordinates (coordinates that can be used to create a polyline on a map) - Distance (in both miles and kilometres) - Success flag or error message (e.g. "Cannot connect to server" or "API Key has exceeded its daily limit" etc.) Additionally we would like the API to be accessible only if a valid "API Key" is supplied in the URL. This means we need a password protected API Key management facility. ...

I'm looking for a senior software developer to build a Cordova app and its REST service in Delphi. This is supposed to be a pretty basic implementation that I will expand and complete later on, so it needs to be very clear. Basically the app will allow an user to either login or register, it will show some general information and retrieve and upload some user specific data. Please see below all details. REST Service: ============= - written in Delphi XE2 or XE5 - possibly should work with both - support for win32 / win64, I would prefer firemonkey for future Linux/Mac support - uses one of these REST implementations - please state which one you suggest and why * mORMot - currently this is my preferred way * datasnaps * other - no DB access is required at the moment as it will be added afterwards, but the REST API needs to be correctly implemented. - I will provide the API, but I'd like to receive some feedback or opinion Client App: =========== - written in Cordova + jQuery -...
