• Is there a structured source of Holland Code (RIASEC) data available?

  - by Arian Kulp

  I'm trying to put together some career-related resources and I need access to the Holland Codes/RIASEC that classifies interests and skills to occupations. I can find many sites that already do this, but I can't find raw data in a structured format. Is anyone aware of a source for this. It can be commercial with licensing fees, though free would be nice! Thanks!

• iPhone plist data, large amounts of text and return key?

  - by user278342

  Basicly iv built my app using a plist. But with the data there is a few times when I need to press return and start a new line. The return key doesn't work in the plist. If I did it the older way it would be \n\n but that doesn't work either. Is there a obvious way I'm overlooking? Or will it be a case off just pressing the space bar allot? Thanks

• Does this data structure have a name? Sort of a "linked matrix"?

  - by Bob

  Let's say I wanted similar functionality to a doubly linked list but needed a matrix instead so that each node was structured like this: public class Node { Node Up, Down, Left, Right; object Value; } Is there a name for such a structure? I've looked through this Wikipedia listing of data structures but didn't see anything similar. Unless I just missed it.

• Can't get the JSONP workin' with WCF Data Services...

  - by SevilNatas

  What am I missing here? It seems from all that I read and watched, exposing JSON from a WCF Data Service should be as easy as adding the '[JSONPSupportBehavior]' directive in front of the Service Class. Problem is VS2010 doesn't recognize 'JSONPSupportBehavior'. Is there a reference I am missing? Seemed like, from alll the articles, it was supportted outta the box. TIA S.

• What is a 'better' approach to query/save from server: DTO or Wcf Data Services?

  - by bonefisher

  From my perspective, the Data Services and their query approach is useful when querying simple object graphs from your server-side domain model. But when you want to query complex dependencies I couldn't create anything good out of it. The classic DTO approach is fine-grained and can handle everything, but the downside is that you have to create Dto classes for every type of server-request which is time consuming and you have to synchronize the Dto type with your domain entity/business logic.

• If I create a transient property in the model, isn't this managed by core data then?

  - by mystify

  Just to grok this: If I had a transient property, lets say averagePrice, and I mark that as "transient" in the data modeler: This will not be persistet, and no column will be created in SQLite for that? And: If I make my own NSManagedObject subclass with an averagePrice property, does it make any sense to model that property in the xcdatamodel file? Would it make a difference if I would simply create a property in my subclass and not model that in the entity? (I think: yes, it doesn't matter at all ... but not sure)

• Which data structures and algorithms book should I buy?

  - by Hei

  I know C and C++ and I have some experience with Java, but I don't know too much about Algorithms and Data Structures. I did a search on Amazon, but I don't know what book should I choose. I don't want a book which put its basis only on the theoretic part; I want the practical part too (probably more than the theoretical one :) ). I don't want the code to be implemented in a certain language, but if is in Java, probably I would happier. :)

• Excel macro to change external data query connections - e.g. point from one database to another

  - by Rory

  I'm looking for a macro/vbs to update all the external data query connections to point at a different server or database. This is a pain to do manually and in versions of Excel before 2007 it sometimes seems impossible to do manually. Anyone have a sample? I see there are different types of connections 'OLEDB' and 'ODBC', so I guess I need to deal with different formats of connection strings?
