Interesting, this seems to be a SIMD-optimized implementation of delta compression (or very similar, anyway). That's a clever idea.
edit: Apparently this isn't actually a SIMD implementation, so it's basically just a variant of delta compression with no particular advantage (or disadvantage).
Yes, I guessed that it doesn't have a negative connotation for you. That's why I mentioned it, so you could be aware of what the name brings with it in part of the world - perhaps I should have been a bit more verbose about that.
The background is that Hitler used "Hart wie Kruppstahl, zäh wie Leder, flink wie ein Windhund" (Hard as Steel from Krupp, tough as leather, fast as a greyhound) in a bunch of speeches about how to model the german youth. Additionally Krupp Stahl was using forced labour during the war.
