The assumptions that I have are - Representations have a definition which have its last modified date. E.g., Script that generates a JSON representation of a resource has when the script has been last modified.

I decided to test the theory that work expands to fill the time given and give myself as little time as feasible to complete my preparation for this exam. My appointment is in exactly one week and I started preparing yesterday. I have a lot of experience designing web-centric applications but not that much in the way of EJB. My goal is t...
I want to build a flowcharting application in Qt to get some practice modeling GUI applications. All it has are draggable boxes and circles that can be connected with straight lines. As this is my first GUI application, I am unsure how one typically designs such a project. Here are my two designs. 1) Build a bunch of model classes (Bo...
Hi, I'm currently implementing a Monotouch application that will eventually be ported to Monodroid. The application is just a client to an OData Web service. Nothing too fancy or performance critical. The challenge is to reuse as much code as possible. I'm aware that the UI APIs for Monotouch and Monodroid are quite different, but I'm...

I have a custom tree data class, following the standard Composite pattern. I obviously don't want the GUI and the model to be too closely tied, so the GUI should be an Observer of the model, and changes should be done through the model layer. I'm implementing observable support using C# events - so far, so good, and I have a working syst...
In old versions of tomcat (like 3.2) you can find the recomendation to serve static content in a apache web server and leave the dynamic content to the tomcat itself. At the new versions of the tomcat docs you cannot find any reference to this practice even at the mod_jk configuration tutorial. So I am wondering. Is still true that tom...

The client is responsible for presenting the data objects and providing dialogs and wizard to allow the user to update these objects (i.e. adding/editing a user). Initially I thought I'll just make the DAL objects have a universal data provider object so they can...

Application I develop requires several data sources (2 RDBMS and one file storage) to operate. I'm going to incapsulate datasources with DAL library & Business Logic layer.
