I'm implementing a comment control that uses an ASP.Repeater to display each comment. The comment itself is currently displayed using a table to divide up some images to display the comment in a bubble. I know that tables are supposed to be the epitome of evil for design layout, and really expensive to display for the browser, but I'm ...
I've been programming c++ for four years and java for two, I feel that I have a strong grasp of the languages them selves, although I'm no wizard in either. It seems that once I hit the 75% completion mark my code seems to be a god awful ball of spaghetti mess, sometimes to the point of unreadability. What have you done to produce good ...
What is the best way (in C++) to set up a container allowing for double-indexing? Specifically, I have a list of objects, each indexed by a key (possibly multiple per key). This implies a multimap. The problem with this, however, is that it means a possibly worse-than-linear lookup to find the location of an object. I'd rather avoid dupl...
If I am writing a library and I have a function that needs to return a sequence of values, I could do something like: std::vector<int> get_sequence(); However, this requires the library user to use the std::vector<> container rather than allowing them to use whatever container they want to use. In addition, it can add an extra copy o...
What principles do you generally follow when doing class design? ...
What is separation of concerns? What's a concern? How might one partition an app into these "different concerns"? ...
Should entities have behavior? or not? Why or why not? If not, does that violate Encapsulation? ...
When using an IoC container, is it considered good design to inject other classes into them? i.e. a persistence class ...
Are there any tips or tricks to make my classes and application designs more modular? ...
Does Information Hiding mean I should minimize the number of properties my classes have? Is that right? Do you tend to make your classes private fields with methods? ...
What are the pros/cons of using black-box reuse over white-box reuse? ...
The most basic task in an object oriented environment is executing a method on an object. To do this, you have to have a reference to the object on which you are invoking the method. Is the proper way to establish this reference to pass the object as a parameter to the constructor (or initializer method) of the calling object? If object...
Looking for some sort of tool that would allow me to layout my page visually using some sort of GUI, then generate the necessary CSS that would allow a web page to look like that. I am new to this sort of thing, so please tell me if this is even possible! ...
Normal practice is to use case studies, construct work- and data-flows, etc. But this does not necessarily create a shared vocabulary between the user/sponsor and the analyst-designer: one or the other, both normally, will have to acquire terms and views of the "internals" of the others area of expertise, and this usually leads to misund...
Table1: Everything including the kitchen sink. Dates in the wrong format (year last so you cannot sort on that column), Numbers stored as VARCHAR, complete addresses in the 'street' column, firstname and lastname in the firstname column, city in the lastname column, incomplete addresses, Rows that update preceeding rows by moving data fr...
Few years back everybody in our shop was crazy with UML. Now everybody seems to have cooled off. I am curious if there is still widespread use of UML in software projects. If so, is this usage limited to whiteboarding? Do you use it for documentation? Do you use tools to generate code from it? Related: Is UML Practical? ...
There is a lot of relativity involved in working with exceptions. Beyond low level APIs where exceptions cover errors raised from hardware and the OS there is a shady area where the programmer decides what constitutes an exception and what is a normal condition. How do you decide when to use exceptions? Do you have a consistent policy r...
In Toyota manufacturing lines they always know what path a part have traveled. Just so they can be sure they can fix it of something goes wrong. Is this applicable in software too? All error messages should tell me exactly what path they traveled. Some do, the error messages with stack trace. Is this a correct interpretation? Could it b...
I've started programming more in OO style than ever (Python). Any good web resources I could read? I need help constructing and modelling objects, relations, interfaces etc. . Not only dry theory (I've read that), but something easy to grasp (examples would be nice), do you know any site or a good book? ...
A two parter: 1) Say you're designing a new type of application and you're in the process of coming up with new algorithms to express the concepts and content -- does it make sense to attempt to actively not consider optimisation techniques at that stage, even if in the back of your mind you fear it might end up as O(N!) over millions o...
