Re: Java Scala report.

I'm very sorry gus for my late response. I closed blog. I found that using Scala, Akka, Play 2.0 or Neo4J is possible on RPi but it is totally inefficient (not enough RAM, not enough power). But I successfully wrote few programs in pure Java (simple rest servers using Jetty + Jackson + Jersey). This...

Excuse me.

Do you know why there is no new commits at https://github.com/raspberrypi/firmware/ for a month?
Is there any change of way how new firmware is distributed?
Or maybe there were some problems with latest work?

Thanks:)

Re: JavaSE Embedded 8 + JavaFX for Raspberry PI (hard float)

I gave my Raspberry Pi to one of our JVM devs so I can't test but the hardfloat JVM should be 10-20% or so faster on anything that involves system calls (graphics, I/O, etc). You may not see this on I/O microbenchmarks since - if I understand correctly - the RPi has a hardware bottleneck with ether...
