Dalvik VM Internals
Dan Bornstein (Google)

Dalvik — the virtual machine with the unusual name — runs your code on Android. Join us to learn about the motivation for its design and get some details about how it works. You'll also walk away with a few tips for how to write code that works well with the platform. Be prepared for a deep dive into technical details. Questions encouraged!

  • I haven't noticed Dan's imperfect presentational skills getting in the way of him presenting something not many people know (or care) about.

    FYI, Dan is the designer of the Dalvik VM which makes him the greatest authority on the subject.

  • FYI, at 28:59, that S33KRIT_INFORMA410N is "I am rather fond of muffins." in ASCII. Nice, Dan.

  • Hi Dan, First 10 min i feel torture to listen your seminar by listening your slow , everything is special, so you will become something special...

    Not every one can build virtual machines, those platforms are deserve to the peoples with something special... That is you.

  • Hi Dan, First 10 min i feel torture to listen your seminar by listening your slow pronunciation, then after 30 minutes i got impressed by the contents you are telling then i become ur fan when u started answering to the end developers after 43 minutes...

    Your presentation style is something , your seeing style ,talking style ... continued in next comment

  • lol, i live in the nearest town, Akureyri :P

  • We are working on an upgrade to JNI, which hides the C code from the Java programmer. Have a look at "Returning Control to the Programmer: SIMD Intrinsics for Virtual Machines" for the (ACM) Queue Magazine. It makes sense for google to integrate our approach into future releases of Android, so that Java programmers do not need no write C code. Dalvik VM already does some of this, but not the SIMD stuff, which is really an API add-on on top of Java.

  • he has 1000 000 registers ....
