A nice write up on low-level optimizations on outdated architectures. Now in the world of SIMD, vector instructions and dedicated hardware it is only of historical interest. But still highly entertaining. Learning do put data in a way that is friendly to SIMD-algorithms is a similar skill that is relevant in modern times for a lot of low-level performance-critical code, as exemplified by Swiss table design [1], or internals of many machine-learning libraries.
