I'm developing an iPhone app that uses a user account and a web API to get results (json) from a website. The results are a list of user's events. Just looking for some advice or strategies - when to cache and when to make an api call... and if the iPhone SDK has anything built in to handle these scenarios. When I get the results from ...
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. So each record should be tied to a specific version of the form. This requirement is kind of new, so the existing application was not built with this in mind. I'm looking for dif...
Is there a way to compare all information (aggregates, down to the detail level) between two OLAP cubes? For example, say I wanted to compare one cube created to work with sql server 2000 to that same cube, but migrated to run on sql server 2005/2008 - technically they should both return the same information for all dimension / measure c...
Here's a question for all you Silverlight guys. In the old days for WinForms, if your user was creating/editing some information in a DialogBox, it was easy to detect the Window closing and if the data was dirty, ask if they wanted to save. My question is, how do you approach this scenario in Silverlight where everything seems to be do...
What's the best way to embed data fields in text so they are easily retrievable, and don't affect readability (much)? For instance, I could do something like "Some instructions here, followed by @firstname:John @lastname:Smith\n", and then write code to parse out the fields. Then I could begin to work out the problems, like embedded...

The question pretty much says it all, but I'm building a compiler and am trying to decide on what sort of data structure to use for my symbol table. Considering the only functions the symbol table will need is a search and an insert I'd like to use a data structure that can do those as quickly as possible. Any suggestions? ...

Hi there! I read (twice) this very useful article: http://blogs.adobe.com/flexdoc/pdfs/modular.pdf And, I know that the best way to make a connection from my main app to my modules is through interfaces. So, my problem is, how can I implement an interface so my module can send and receive data from my main app?, cuz, I understand that...

I've got a UITableView with several entrys, and these are divided up in several sections. If I click on one of the cells, a DetailViewController is accessed. In that DetailViewController, I want to use the data from the selected cell (the cell.textLabel and the cell.detailTextLabel), but I can't access these. Is there a possibility to so...
If you search for skips lists implemented in Haskell, you won't find many. It is a probabilistic data structure needing a random number generator, meaning that any of these structures would need to run in the IO monad. Are Haskell folks staying away from these data structures because it's not possible to implement them purely? How can H...

How does the data in a database in the field get upgraded because a new version of the software is being released? For an example, consider look up data. Usually the look up data associates an ID (number) to a name (string) and then this ID is referenced in other tables instead of the the ID directly (i.e. normalized). There are other ty...
