Presentations
Introduction to Virtual Machines and Interpreters
Have you ever wondered what goes on inside the virtual machines and
interpreters that we use every day?
In this session, you'll see some of the inner workings of Python, PHP, Java, and JavaScript and learn that at the lowest level these languages really are not as different as they may seem.
Virtual Machines and Interpreters II: Inside the Java Virtual Machine
In part II of VMs and Interpreters, you'll dive into the inner workings of the Java Virtual Machines. You'll learn how your Java code is translated from Java source code to byte code and ultimately machine code.
You'll also see tools for viewing Java byte code and measuring performance changes caused by VM optimizations.
