Setup Mac OS X

I'm in a hospital in Spain and my MacBook was stolen.

Now I bought a new one and need to configure it. I have an external hard drive that backup everything using Time Machine, but I don't want all the crap I had in the old one.

1. Run Software Update

Troubleshooting Production JVMs with jcmd

jcmd is a powerful new tool introduced in Java 7. Along with jstack and jps, it should be in your go-to tool for solving production problems on the JVM. (Come to think of it, with this tool you don't really need jps anymore)

Here's an example session with jcmd:

$ ssh wopr.qa.corp.local
$ jcmd -l
34739 sun.tools.jcmd.JCmd -l
