C or Python? Comparison of execution time for Mandelbrot image generation
Because I’ve been generating a lot of fractal images recently, I’ve found myself spending quite a bit of time sitting around waiting for programs I’ve written to finish long repetitive calculations. In particular, I’ve generated several long sequences of several … Continue reading
