A demonstration of Khinchin's constant for the continued fraction expansion of the number pi. Obviously as python has finite precision floating point, this is only an approximation, and is likely to approach an incorrect result as a grows larger.

x = y
while True:
z = floor(x)

OpenCL pseudocode to demonstrate the usual pattern of calling OpenCL
//The code that runs on the graphics card is included in the program here as a plaintext string
//It's also possible to include it as a binary, but I don't know how to do that.
const char* source=
"__kernel \n"
"void sum(__global float* source, __global float* dest, uint n) \n"
" int idx = get_global_id(0); \n"
" int iter = 2; \n"
" \n"
" while(iter < n && idx % iter == 0) { \n"
" dest[min(iter*idx,n)] = source[min(iter*idx,n)] + source[(iter-1)*idx]; \n"

Very simple converter from list of frequencies and durations to output sound wave on stdout. Pipe it through e.g. /dev/audio or aplay to actually create sound.

Visual Studio 2012 - Automatically incrementing version for C#

This requires Microsoft Visual Studio 2012 SDK and Microsoft Visual Studio 2012 Visualization & Modeling SDK, which come separately from Visual Studio 2012. Other version combinations are probably possible, and maybe compatible, but untested. The core of the method is this:

  • Add AssemblyInfo.tt to MyProject\Properties, filling out the "Your xxxxxx" sections.
  • Open up the project file (e.g. MyProject.csproj) in a text editor (e.g. Notepad++), and locate the line that defines the build targets for the language ("import project... microsoft.csharp.targets")
  • Insert the contents of MyProject.csproj there
  • Finally, if you build the AssemblyInfo.tt template within Visual Studio, make sure to set AssemblyInfo1.cs to Build Action: None in the File Properties window. This will fix any errors about duplicate definitions.
