Lately I have seen our development team getting dangerously close to the 'second system syndrome' type ideas while we are planning the next version of our product.

What are some possible designs to deal with frequently changing data forms? I have a basic CRUD web application where the main data entry form changes yearly.

I'm developing a few custom ant tasks that all need to initialize the same objects. I wanted to initialize those object's in a common superclass that extends from Task, in the init() method. But I see from the lifecycle of an ant task that init() gets called before the tasks child elements and attributes are set. So all of the data I ...
I am new to GUI design and am struggling a little to decide whether my intended use of inheritance is acceptable (I am familiar with the general concept of favouring composition). For example, if I have a GUI that will feature 3 JToolBars (two toolbars at the top and a status bar at the bottom) as I see it I have 2 obvious options: Si...

Say I have a number of usercontrols, each usercontrol inside a tabitem, inside a window. For example, let say this is a food collection application. Then we have tabs Fruit, Vegetables and Snacks. Each tab will show a list of food of that subject, and allow the user to add, delete, modify the food in each section. The food is stored in ...
In my system clients register through web service on a server and then communicate by peer to peer communication only among clients, without server. When client signs out, he informs server that he's leaving. But if he signs out because of any crash or unexpected situation, server will not be informed. How do you normally handle such sit...

Like the title suggests, I am looking for a good read on Java application design that leverages Spring. When I read different examples on the internet or the Spring official documentation, I had this feeling that every author out there presumes that you are good with patterns. Buzz words like DAO, Singleton and etc are used a lot. As an ...

The player can drag the blocks to 16 places on a floorplan and if done right they will see the whole castle....
I have recently started learning unobtrusive JavaScript. Using JQuery its really fun. However with this thinking of writing JavaScript code has come a real long way from traditional ways. Also adding quick onclick="fun()" is helpful sometimes and as the application grows 100% unobtrusive code "sometimes" become difficult to write. Like ...
