Benchmark Just for fun, I tried to run a FFT program from the IBM Ninja (Numerically Intensive Java) package. After implementing a few more native methods, it ran, but to my surprise it ran about as fast as under JDK 1.4 (with Sun's Hotspot VM). Not bad for totally unoptimized code ;-) The cfft.java source that I ran can be viewed here, the resulting executable (in a zip) can be found here and I've updated the project snapshot. For the array package, follow the Ninja link. 11:28:37 AM    Comments

J# released Yesterday, Microsoft released J#. When I first looked at it yesterday, I was happy to find that they fixed the huge flaw that existed in beta 2. In the final version they have made java.lang.Object and java.lang.String aliases for System.Object and System.String. So they no longer require a "VerifierFix" to convert System.Object references to java.lang.Object references. Even so, they've decided to remove the AllowPartiallyUntrustedCallers attribute from the J# runtime libraries. Unfortunately, the rest of the story isn't so positive. In only an hour of trying to compile my Java code, I already encountered three bugs in the compiler and one in the runtime. So I remain very sceptical about the quality of this product. 10:34:38 AM    Comments
