Re: [Neo4j] Oracle suing open source product developers using Java
Suryadev, the lawsuit against Google is regarding the implementation of JDK, JRE and libraries being API - compatible to Java but not attributing and licensing it with Sun/Oracle Java. It has nothing to do with anything built on top of the Java specification and clearly stating so, like any Java application (Neo4j being one). So, please stop spreading FUD to the Java community about this.

Re: [Neo4j] Oracle suing open source product developers using Java
Isn't the Oracle-Google suit against the jvm-like internals of Android, rather than the fact that the application developers use Java? Besides, afaik patents are language independent, so that won't matter much anyway. But fortunately, Neo4j isn't an American company, but European. Software patents aren't so common in the EU, nor are software patent based lawsuits. Anyway, I think you blow things way out of proportion now. Although I'd have to agree that the Oracle-suit is rather silly (they're probably hoping to get some piece of the pie by getting a license agreement with Google).

Precisely, Arjen. The likely outcome is one of the many cross licensing agreements that exist between the big software companies.

Re: [Neo4j] Use of LuceneFulltextIndexBatchInserter
I posted a question on MathOverflow http://mathoverflow.net/questions/35563/best-algorithm-to-use-for-a-bus-train-transport-route-planner and I emailed the authors of the slides, hopefully we can get some more insights into the bidirectional A* or the best algorithm to use. A lot of research has been done in this field, this describes a A* algorithm with landmarks: : http://www.optimization-online.org/DB_HTML/2008/11/2154.html Also the Dijkstra’s Algorithm On-Line: An Empirical Case Study from Public Railroad Transport paper also looks good cheers Paddy On Fri, Aug 13, 2010 at 10:06 PM, Paddy paddyf...@gmail.com wrote: Thanks Peter, Sounds good, Yes that would be a great addition to the graph-algo!
