Can't wait to read a copy. The title is great. I knew exactly what this was about before I clicked through. I've also enjoyed your blog over the past few months, especially your post on the Eytzinger Layout [1], which we've implemented for TigerBeetle's new deterministic LSM-forest [2]. I can also understand your decision to write the examples in C++ given all the legacy code that's out there and given the easy access to std lib examples which are often not optimal. However, if I may make one suggestion it would be to take the extra time now to rewrite the examples in Zig — it's a clearer, simpler, newer language that makes sense for high performance coding for the next 10-20 years. It has a great approach to SIMD intrinsics and shares many of the same performance values as your book. For example, the std lib ships with SoA that can be used to generate SoA layouts at comptime. As an orthogonal language, it's also brilliant for book examples, notably very readable, and also guaranteed to compile on the first attempt—it will make the examples more engaging and accessible, to bring the cool performance ideas across cleanly to your readers, without abstraction overhead, unnecessary complexity or usability issues. From a community point of view, I think that this change would also find you a very engaged, supportive and concentrated systems community right from the get go.
