being a java-centric shop, they need to really understand the java
virtual machine (especially the one they are using), which means
understanding a bit of real internals - it has surprised me how many
"mini-tutorials" are required to explain such concepts; and know what
the effects of certain options behave on all the OS's the vm's are
supposed to run.
