good 'ole NIH in the Linux community

You could try to be less inflamatory. DTrace was hardly an original idea at Sun, either. You claim SystemTap is a "Linux-born DTrace-knockoff". By that logic, I could claim that DTrace is a Sun-born knockoff of the tracing work IBM did years ago. Sure, Sun have made some big improvements to the art of tracing, such as the D language, and a massive improvement it was too. As are some of the other innovations that have come from DTrace. But that's how the progress is made in this industry -- by building on work done by others. DTrace is not the be all and end all of tracing, and claiming that NIH is the reason behind SystemTap doesn't really help anything at the end of the day. Both DTrace and SystemTap are useful products and have their place in the world. DTrace is good enough to stand on its own technological merits, without the needless put downs aimed at SystemTap (which pretty much everyone agrees is currently lagging DTrace by some margin). You're rightfully proud of the work you've done on DTrace, but perhaps a little less hostility to the competition might be appropriate...

I'll call that bluff. What technology are you referring to, exactly? Or more concisely, in our 2004 USENIX paper, what piece of related work did we neglect? I'm eager to see what technology you're going to parade out as an example of dynamic instrumentation done "years ago" at IBM -- at least we'll be talking about concrete technology and not licensing!
