I am reading about SURBLs (known spam hosts), for purpose of classifying spam, as a batch process. Main access method seems to be via DNS lookups. I was wondering what's the usual way to do such lookups from Java code. Since this is a batch process with no strict performance requirements, I think most important feature would just be simplicity.
I have a neural network written in Java which uses a sigmoid transfer function defined as follows:
private static double sigmoid(double x)
{
return 1 / (1 + Math.exp(-x));
}
and this is called many times during training and computation using the network. Is there any way of speeding this up? It's not that it's slow, it's just that it is used a lot, so a small optimisation here would be a big overall gain.

I'm trying to extend a Java Swing component in Clojure, i.e. I want to extend a javax.swing.JComponent and add some custom methods implemented in pure Clojure in addition to all the standard inherited methods.
I've tried using "proxy" which works great if I just want a single instance (in the same way as an anonymous inner class). However I'd really like a named class so that I can generate an arbitrary number of instances.
What's the recommended way of doing this?

I have a big XML which contains around 300 elements. I need to modify 2 or 3 elements in this xml using Java. I don't want to go for conventional marshalling and unmarshalling as it involves the parsing of the whole XML. How is XPath/XSLT manipulation? I know that I can easily read the data but i need to modify the same and put in back in the same XML. The primary concern here is performance. Kindly advise

From what time I've spent with threads in Java, I've found these two ways to write threads.
public class ThreadA implements Runnable {
public void run() {
//Code
}
}
//with a "new Thread(threadA).start()" call
public class ThreadB extends Thread {
public ThreadB() {
super("ThreadB");
}
public void run() {
//Code
}
}
//with a "threadB.start()" call
Is there any significant difference in these two blocks of code?

In Java, is there any way to create an instance of any class that extends abstract class A, inside a member method of class A? Classes that extends abstract class A will return their instances with this method, but i don't want to implement same method in all subclasses with a "return this();" kind line.
