Well most of my friends don't get to see my work. My main gig is creating customer Java training for Oracle. For example, the main Java programming course: Java SE 7 Programming.
Well my current assignment is to create some free content for the Oracle Learning Library. So my first tutorial is out:
Java SE 7: Reviewing JVM Performance Command Line Tools
OLL Entry | Tutorial Link
The tutorial covers some of the built in command line tools included with Java 7. With the tools, you can query running JVMs and find out a great deal of information about them. So if this sounds interesting check it out.
