Heyho, I'm searching for a tool like JDepend to draw a graph for a java classfile. JDepend seams to be fine, but it's not resolving the deps from the deps (maybe I'm just missing some special options?). A direct output into .dot format or an image would be nice to have. Thanks ...

The file-structure is essentially a list of file-paths where each path is a string connected with 1 or more data-block ids (256-bit reference to the actual data-block). A data-block can be referenced by seve...

I'm currently working on building an application in CakePHP. There's a quite extensive existing data set that's conceptually a tree, but wasn't previously stored as one. What I mean by that, is there's no real relationship defined in the data. The problem I'm having is getting it to work correctly with the CakePHP tree behaviour. B...
