For example, the Twitter for Android application that we worked with Twitter to design gives you, the 3rd party developer, a working example of how you can customize and build an application that’s both fun and highly functional.

In this post, I'll take a high-level look at how malloc is implemented on the Mac. I'll look at how memory is allocated for "tiny", "small" and "large" allocation scales, the multi-core performance improvements introduced in Snow Leopard and some inbuilt debugging features you can trigger for finding memory problems including buffer overruns.
