• Why would a static inner interface be used in Java?

  - by Mo

  I have just found a static inner interface in our code-base. class Foo { public static interface Bar { /* snip */ } /* snip */ } I have never seen this before. The original developer is out of reach. Therefore I have to ask SO: What are the semantics behind a static interface? What would change, if I remove the static? Why would anyone do this?

• How to spot undefined behavior

  - by BlueRaja - Danny Pflughoeft

  Is there any way to know if you program has undefined behavior in C++ (or even C), short of memorizing the entire spec? The reason I ask is that I've noticed a lot of cases of programs working in debug but not release being due to undefined behavior. It would be nice if there were a tool to at least help spot UB, so we know there's the potential for problems.

• How does WCF RIA Services handle authentication/authorization/security?

  - by Edward Tanguay

  Since no one answered this question: What issues to consider when rolling your own data-backend for Silverlight / AJAX on non-ASP.NET server? Let me ask it another way: How does WCF RIA Services handle authentication/authorization/security at a low level? e.g. how does the application on the server determine that the incoming http request to change data is coming from a valid client and not from non-desirable source, e.g. a denial-of-service bot?

• Java design flaws that are unlikely to change due to backward compatibility

  - by koppernickus

  What are the Java language and standard library design flaws you are aware of? I ask only for flaws that: cannot be changed or are unlikely to change due to backward compatibility, are NOT controversial, i.e. most of programmers would agree that "this is a bug not a feature" (for example checked exceptions seem to be controversial language feature, so I wouldn't classify them as "design flaw").

• Visual Studio Question: When doing a compile/debug is VS suppose to delete existing files in the bin

  - by Greg

  Hi, Q1 - When doing a compile/debug is VS suppose to delete existing files in the bin\debug area? (for VS2008) if no then can I ask please: Q2 - My winforms checks for existance of a sqlite.db3 file and creates it if it needs to (programmatically). If the behavior I wanted was that each Compile/Debug I do is for the target Debug area to be clear, so that the program would exercise the code that builds the database file, how would I organise this? thanks

• What is the best way to format a date in JSON for Mongo DB storage

  - by Poul

  I have a date with a time. I'm using ruby, but the language shouldn't matter. d = "2010-04-01 13:00:00" What is the best way to format this date for Mongo DB? By 'best' I mean, is there a certain format I could use where Mongo would recognize it as a date and might give me more-advanced filtering optons? ie: If formatted correctly, could I ask Mongo to return all records whose month is '04'? Thanks!

• Deploy only cube schema, without processing

  - by Ken Yao

  Is there a way to only deploy cube schema, but without processing the cube. It seems in Visual Studio, when yo deploy a cube, by default, it is "Deploy and Process". The problem is processing takes so much time, and my main purpose is just writing some MDX script and see if it works well against the cube structure. It seems processing whole cube is just over kill. So I ask.
