A few weeks ago I gave a couple of workshops on DTrace (one all day; one half a day) designed to introduce people to using DTrace and the D language. I just posted a copy of the presentation on my weblog: http://blogs.sun.com/roller/page/ahl?entry=dtrace_boot_camp The presentation is a work in progress, but it should be helpful as it is. If you have any feedback, please let me know. Adam -- Adam Leventhal, Solaris Kernel Development http://blogs.sun.com/ahl
