Why do most spreadsheets contain a hard-coded limit on the number of rows and columns?
Why are programs like Microsoft Excel, Gnumeric and OpenOffice.org Calc designed with hard-coded limits on the number of rows and columns? This seems like an archaic programming technique from when spreadsheets were considered a demanding application and dynamic memory allocation was considered "high-end". I would guess that it indicat...
Scaling singletons
After having some difficult hours mulling over some architecture issues for my server-based application, I feel I am going to have to use singletons to accomplish my goal. Purely for the following reasons (justifying my smell): I don't need to pass expensive objects deep into a call stack I can perform functions on singleton management...

Ravioli code - why an anti-pattern?

What are the pros and cons of using a Data Services Layer?
This is a discussion that seems to reappear regularly in the SOA world. I heard it as far back as '95, but it's probably been a topic of conversation long before that.

What is the relationship between a code smell and an anti-pattern?
In my mind I think that an anti-pattern is the cause, and a code-smell is just one of man possible symptons. Is this correct? For example: God class antipattern -> large class code smell Not Invented Here Antipattern -> code that should not even be there Analysis Paralysis anti-pattern -> no code smell results, but leads to bankcruptc...
Is a generic model an antipattern?
Now I have something that I have not seen it before: the database is really generic. For example: instead of a concrete type we have a generic one: device, and it relates to a custom properties table. Unfortunatelly, the model over its entities represents those tables, so the model does not talk about the business at all. At the end p...

Is this an acceptable UI design decision?
OK, while I'm on record as stating that StackExchange UI is pretty much one of the best websites and overall GUIs that I have ever seen as far as usability goes, there's one particular aspect of the trilogy that bugs me. For an example, head on to http://meta.stackoverflow.com . Look at the banner on top (the one that says "reminder --...
Initialization of components with interdependencies - possible antipattern?
I'm writing a game that has many components. Many of these are dependent upon one another. When creating them, I often get into catch-22 situations like "WorldState's constructor requires a PathPlanner, but PathPlanner's constructor requires WorldState." Originally, this was less of a problem, because references to everything needed wer...
