C9 Lectures

2010: Introductory STL (10 parts)
- microsoft/nurikabe: I open-sourced and slightly modernized my Nurikabe puzzle solver.
2011: Advanced STL (6 parts)
2012-2013: Core C++ (10 parts)

BoostCon (now known as C++Now)

2009: I am not aware of recordings for my talks "C++0x Support in Visual Studio 2010" and "The Parallel Patterns Library in Visual Studio 2010". You aren't missing anything, though.
2010: "Data Structure Visualizers in Visual Studio 2010" is irrelevant as the old visualizer machinery has been completely replaced by something much better (and documented).
2012: Regex In C++11 And Boost

tiny guitar synth in 96 chars of C

works by starting with a array filled with white noise (from /dev/urandom), then continuously modulating it with a low pass filter of the desired frequency.

this results in a sound pretty similar to a guitar with steel or nylon strings.
