		<description>Thanks for the pingback, Josh!

It&#039;s going to take a while for DTrace to appear on Linux, because of some silly licensing problem - a bunch of kernel work is required to support DTrace, and the Linux kernel is licensed under GPL, so the idea has to be re-implemented under GPL.

I posted some comments back on my blog about this as well.</description>

		<description>Damn, beaten by Erik.

I too was gonna pop in here to burst your bubble :D What&#039;s even better about the Mac version is that they&#039;ve made a beautiful graphical wrapper around it as well. Nice!</description>
