• Good Java graph algorithm library?

  - by Nick Fortescue

  Has anyone had good experiences with any Java libraries for Graph algorithms. I've tried JGraph and found it ok, and there are a lot of different ones in google. Are there any that people are actually using successfully in production code or would recommend? To clarify, I'm not looking for a library that produces graphs/charts, I'm looking for one that helps with Graph algorithms, eg minimum spanning tree, Kruskal's algorithm Nodes, Edges, etc. Ideally one with some good algorithms/data structures in a nice Java OO API.

• How to change the coordinate origin in Flash's stage with Actionscript?

  - by Petruza

  I think I did this before but can't find the code. Flash as many other graphical frameworks use the top-left corner as the coordinate origin (0,0) because it's how the underlying memory model is by convention. But it would be really simpler for my calculations if the origin was in the center of the stage, because all the game revolves around the center and uses a lot of trigonometry, angles, etc. Is there some built-in method like Stage::setOrigin( uint, uint ); or something like that?

• Managing Java dependencies in a Grails application?

  - by Stefan Kendall

  I'm trying to adopt my development from Spring/Maven2/Tomcat -> Grails, and I'm wondering if there's an easy way to manage dependencies in grails separate from maven. Maven does a lot of the magic that grails is doing automatically (unit testing/building/etc.), so I wonder if there's a need for maven at all in grails projects. So, then, how do Grails users generally manage java dependencies? I've become accustomed to central repository dependency management, and I can't turn back at this point.

• Why use NoSQL over Materialized Views?

  - by JustinT

  There has been a lot of talk recently about NoSQL. The #1 reason why I hear people use NoSQL is because they start to de-normalize their DBMS data so much so, to increase performance, that they end up with just one table with all of their data within that single table. With Materialized Views however, you can keep your data normalized, yet have it stored as a single table view for the same reasons why you'd use NoSQL. As such, why would someone use NoSQL over Materialized Views?

• BlackBerry use of the simulators

  - by user301467

  Hallo, on the BlackBerry homepage you can download different simulators for every different model. There are a lot fo simulators there... My question is, how do you develop BlackBerry applications: do you use the simulators - can you relay on them. If an application works on the simulator, does it works 1:1 on the phone? Do you develop for every model a different UI, as the screensize is different? Thanks you very much for your replay?

  - by ssaboum

  Hi everyone, i'm trying to use Nexus + m2eclipse/maven-3 professionnally, and i've got a huge 3rd party library that needs a lot of dependencies. Is there any ways to ease my pain by uploading to Nexus this third party library with all its dependencies linked, so that anyone who would need it would just have to add the maven-dependency-tag only for this huge library ? Do i need to create the pom myself ? thank you for your help.

• Adobe Flex 4.0 vs Silverlight 4.0

  - by Jason Towne

  While this not necessarily a technical question, I believe it will help a lot of developers (including myself!). With Silverlight 4.0 and Flex 4.0 both in beta, I thought I would put out an open question to the community and see what everyone likes and dislikes about each framework and why. I've worked with Flex in the past but have decided to take another look at Silverlight with the new version being released. Thoughts anyone? Edit: Made it a community wiki. :)

• GWT ScrollTable performance problem

  - by wolfi

  Hey all, I'm having a little performance problem with the gwt (incubator) ScrollTable. It's rendering really slow. Not even when I'm loading a lot of data - it happens already with a few rows. Or is it possible that the deserializing of the data takes so long? I'm using GWT 2.0 and IE. Maybe someone has the same problem or a solution for it. Thx and Happy Easter!
