We will have two short presentations this month, one by Adam Jones on the Accelerate framework, and another one by Robert Boone about the open source vfrReader PDF library.
Description: The Accelerate Framework is a collection of C APIs for vector and matrix math (BLAS and vecLib), digital signal processing (vDSP), and image processing (vImage). It provides a generic API which optimizes the binary for each specific processor's specialized math instruction sets. For instance the NEON SIMD instruction set in ARM Cortex 8 and 9 (Apple A4, A5+) allows single instruction 64 or 128 bit data operations (like multiplying two vectors as one operation). For large data sets the performance improvements can be staggering.
Bio: Adam is currently a mechanical engineer, looking for a more challenging field. He has been doing iOS development on the side for the past two years, with a long history of programming for fun and research.
vfrReader PDF library
Description: We will go through a brief tour of the PDF libraries available currently, and then review the vfrViewer application. We will perform a simple modification of vfrViewer, which will be an interesting demonstration of what this library can do.
Bio: Robert began his career as a student programmer building West Texas A&M's online university in PHP. He later became the system administrator and ultimately the webmaster for the university. In 2006, he joined cpanel, inc as a Perl developer. In 2012, Robert formed JRLBConsulting, where we works on client projects focusing on iOS and Ruby on Rails.
