Chuck Moore, creator of Forth, gives his annual Fireside Chat at Forth Day 2011 at Stanford. He talks about his multi-core GreenArrays chip design and demonstrates code running on it.

Chuck Moore, inventor of Forth, presents GreenArrays' 144-core asynchronous chip at Strange Loop 2013. He explains how idle cores draw almost no power and how tight code minimizes energy use.

Andrew Kelley, creator of Zig, presents practical data-oriented design techniques for shrinking memory footprint and making programs cache friendly. He ends with a case study of how these ideas sped up the Zig compiler.

Mike Acton of Insomniac Games argues that a program's purpose is transforming data, and shows how common C++ approaches work against that in performance-critical game development. He covers cache behavior, data layout and the limits of compilers.

Kate Gregory argues at CppCon 2015 that C++ should be taught without starting from C: no char* strings, printf or raw arrays at first, with references before pointers.

Noel Rappin's MountainWest RubyConf talk introduces Smalltalk to Ruby programmers. He compares the two languages' object models, blocks, 1-based arrays, simple syntax and live programming environment, and walks through sample code.

Aaron Hsu shows how to manipulate and transform tree data in APL using arrays and inverted tables instead of pointers. He claims much smaller code, better performance and easier parallelisation.
