Escape Analysis changes the rules for performance critical code

The last few days its been dawning on me how Escape Analysis changes the rules on performance critical code.

Its a big deal. Short lived objects become nearly free to use. Convenience rules. If you need to tuple-ize 2 Ints, then stick them in a List, to pass through an API, only to immediately unpack back to the Ints on the other side: go ahead. Dont worry. Those objects probably will never be created; they’re conceptually there.

Get back to what you ought to be doing: Abstracting and Composing.

    Hey All,

    My company, Hooked Media Group, is hosting a webinar on April 15th. Thought you all would be interested.

    The webinar is for the first 50 developers and will give a look into its latest addition to our product, Yoo-Mee.
    The goal of Yoo-Mee is to make your games social by allowing your players to interact with each other and receive immediate results and gratification through winning prizes, fun gifts, and cash. You get additional monetization for your games and better hooks to keep your players coming back. (Yoo-Mee works with existing game platforms.)

    Plus One lucky developer wins an iPad just for attending!

    Please email us at by April 14th 9pm EST (6pm PST) to get in on it!
