The idea is to create a second Math.* library that merely promises 'more or less accurate results' without specifics, so that those COULD use hardware accelerated functions).[15:33:14] <surial> Alpounet: And for micro-benchmarking: Java's design is: I'll run everything slow as molasses and instrument the crap out of it, because on a modern processor, doing anything = doing it instantly. Only when I notice that a certain loop gets run all the time, will I stop the entire VM, use very smart algorithms to recompile this to whatever will run the fastest on this architecture, and then resume.[15:34:16] <surial> this is called hotspot/just in time. To do benchmarking on java, therefore, you need to use increasing loops and make a graph. The graph should be linear with a slope M, then have a peak (that's the recompile), then be linear again, but this time with a MUCH smaller slope Q. (M >lots> Q). Then you've got a more or less valid micro-benchmark.[15:35:02] <surial> the end result is that java can beat C in certain circumstances.

Never use calendar when simple millis math works just as well / better.[17:31:07] <surial> which in this case, is true.[17:31:48] <Seldon75> so, are you saying that synchronizing the block won't solve raav's comodex?[17:31:53] <surial> Seldon75: Yes.[17:32:02] <surial> It won't make one iota of difference. You can create comodexes with only a single thread.[17:32:03] <surial> Here, run this:[17:32:18] <Seldon75> wont synchronizing cause the thread to block until it can access the object being modified[17:32:37] <surial> import java.util.*; public static class Foo { public static void main(String[] args) { List<String> l = new ArrayList<String>(); Iterator<String> it = l.iterator(); l.add("foo"); System.out.println(it.next()); }}[17:32:47] <surial> that whole thing. dump it in a text file called Foo.java, and then run javac Foo.java && java Foo[17:32:50] <surial> et voila, a comodex.[17:32:59] <surial> Seldon75: no, because that has nothing to do with why the comodex is being thrown.[17:33:19] <surial> Seldon75: The comodex is thrown because, and read this carefully: *THE LIST WAS MODIFIED AFTER AN ITERATOR WAS CREATED, AND THEN YOU ACCESS THE ITERATOR*.[17:33:21] *** shaya has quit IRC[17:33:49] <Seldon75> the javadoc says This exception may be thrown by methods that have detected concurrent modification of an object when such modification is not permissible.[17:33:55] <surial> If there's no iterator, then there won't be a comodex. If there is one, and someone messes with the list after creating the iterator, regardless of synchronized or not, you get a comodex.
