This is possibly one of the best written articles end-to-end I have read. Excellent job telling the story

Agreed it was well written, but kinda pointless though since they could have “solved” the problem using the existing tools in a couple lines of code without any new deps. All that content annd profiling and they missed the fact that they were using numpy wrong.

Totally out of curiosity, could you be a bit more concrete in your posted example? I can't get it to work (I'm inexperienced with numpy and I'm messing something when translating your quick example to python)

Thanks!

Yea sorry that was just pseudo code. You want it in this form:

    centers = np.array([
        [3, 3],
        [4, 4]
    ])
    point = np.array([3.5, 3.5])
    vals = centers - point
    np.linalg.norm(vals, axis=1)
