A trivial Keynote '13 document `Index` tree

An example of a Keynote '13 Index tree, unpacked from a document bundle.

  • The document uses the default black template
  • It has two slides:
    • Slide 1 is a simple Title format slide, with title line "My title" and secondary line "My author"
  • Slide 2 is a simple bullet slide with headline "Some heading", a single bullet "Some bullet", and presenter notes "These are presenter notes." (in the default note style, which uses Avenir regular/black as the font)

Created February 17, 2014 22:07
Halide test for error behavior when ulimits prevent sufficient memory allocation
// NOTE: these setrlimit APIs are not implemented in OS X. This should only actually catch failure on Linux.
// TODO: also test overflow on output, intermediate allocations

#include <stdio.h>
#include <sys/resource.h>

size_t memory_limit_bytes = 1024*1024*128; // 128MB - plenty for Halide, not enough for buffers
