Isn't this a job for the compiler? The default would be to have boundary checking, but if the compiler can prove that the index is always in range it can drop the boundary check. From the user's perspective, the boundary check i

Technically it's a rendition of white noise (“Ceci n’est pas une pipe,”). White noise is random, whilst a recording is predictable. There is also a reasonable chance the rendition is a simulation based on a pseudorandom generator.

Think about using the Despain algorithm, derived by recursively decomposing an N-point FFT into FFTs of size sqrt(N). You end up with a bunch of 4-point FFTs where the twiddle factors are rotations by multiples of pi/2, which can be i

It's fun to do a "blind tasting party". Get a bunch of friends to each bring a bottle. Maybe give a criteria, like a price range, so people don't feel obliged to impress with the price tag. All bottles are delivered to

A funky thing is that you can replace the 'N' sin/cos functions used in Fourier analysis with any set of 'N' orthogonal functions (aka basis functions). In this context, a Fourier transform is just a bunch of corre

It's particularly satisfying when a design doesn't just account for parasitic elements but uses them to advantage.
