Dalvik VM Internals

To anyone who is interested in Android, I would highly suggest that you check out this video if you haven't already, called "Dalvik VM Internals".

The video was probably published a long time ago already, but it shows just how much work went into the Dalvik VM by Dan Bornstein and others who worked on the project with him. Particularly, it really explains why it's necessary to think how code will be executed on a machine, even when writing in a high-level language such as Java, which is something C++ gurus have also been emphasizing for years.

Luckily, I do most of my work in C ;-) but I do periodically try to rewrite chunks of software in lower-level languages to mitigate certain overhead. That would involve, for example, converting pure Java or C++ image processing code to C or ASM. The topics covered in this Video do a good job at explaining ways to implement the features of higher-level languages essentially in machine code.

Very good presentation.
