Hey everyone! I just put out a video on Domain-Driven Design. It’s a long one, about 20 minutes, but I really believe it’s worth your time. It took me a lot of time to make, so I hope it helps you, and I’d love to hear what you think! 🙌

Instead of pointer-chasing through B-Tree node hierarchies, this index models the key distribution using streaming piecewise linear regression with strict epsilon error bounds.

Lookups compute positions directly on the CPU ALU before a local L1 cache search, reducing memory by 99% and cutting latency by 3x.

Hey everyone!
