Mark, It's true. My interpretation of Sun's documents: In the more recent versions of Java (1.4, 1.5, etc.), the runtime analysis in the -server option of Sun's Hotspot JVM is able to do several different types of optimization around potentially final and mostly final methods. The most

However, we are finding C++ an exceedingly frustrating language to work in. I won't go into the details here -- we don't need another language war -- but suffice it to say that it seems like we're spending a lot of time messing with details that aren't of interest for the research. Now

C and Java are in my opinion almost the same languages. I think the error rate and nowadays also the speed is very close. i might agree about the error rate, but speed isn't even close, in my limited experience. if you statically allocate all of your ram usage, this *might* be closer to
