<p>Lately there has been a lot of excitement over the use of DTrace for bug hunting and reverse engineering purposes on platforms that support it such as Solaris. But there are a plethora of advanced tools and techniques out therefor other more common x86 based platforms, so does DTrace really add that much?In this talk that question is examined by introducing RSol, a Ruby based debugging component for Solaris in a similar vein to PyDebug for Windows. RSol allows powerful bug hunting tools to be coded quickly, and using this the pros and cons are investigated of using DTrace vs more traditional debugging techniques to achieve different goals in different circumstances. The ultimate plan is for RSol to become a suite allowing debugging and DTrace based techniques to be used together in a complimentary way.</p>
