All the Perl examples I have found tend to be long single function programs and I find my self writing code the same way. Are there any resources or tutorials for writing maintainab...

Say, for example, today your User object contains Name : String and Email : String, but tomorrow you need to add Age : Integer and Address which consists of Country, Zip code, etc. Then you may want to create new field User.Contacts and move Email and Address to th...

The two (basic) ideas I've had are: A bunch of individual pages all with PHP includes to have the header, footer, and menu. A single main page that has the menu, header, and footer, along with an include for the mai...

My application receives strings that represent objects. I have to parse the strings to get the property values for the object I'm creating. Each object will have to know the specifics about how many attributes there are, what each attribute means, etc. However, I want to avoid having each class know about how to parse the string. I'd...
Hi, I have a 32-bit .NET assembly which PInvokes into the C layer. I want to port this assembly to 64-bit. I have read many documents related to porting to 64-bit, all of which seems to suggest that we need to take care of the alignment if we are to use structures. I had a general question related to structure alignment and wanted to c...

How would you structure the information which you maintain to keep all of the information about your projects and clients at your fingertips. We are finding that ours is becoming so large that at times we don't know for sure what we are looking for only that we know it is in the knowledge-base. We use a confluence in a classical hierarch...

Not that I have time to discuss this properly to reach a conclusion and adapt my code because the phase one (of three) of a school project is in 24hrs, but at least I need to know if I did the correct decision.

RESTful design seems to advocate flat or shallow structured representations (at least when resources are represented as XML). A resource representation should contain just the resource, which the URI identifies. I'm wondering when it is sensible to present resource's sub-resources within the parent resource? To elaborate, consider this...
