My ridiculous optimization ventures taken to make the smoothest tower defense.
The server and client tricks that let my tower defense stay smooth with thousands of enemies, lots of units, and a lot happening at once.
Search Algorithms Through the CPU Cache
A look at linear and binary search from the perspective of your CPU's cache hierarchy, including the cases where memory access patterns outweigh Big-O.
Rust Ownership Mental Model
A practical cheatsheet for choosing references, clones, Rc, Arc, Box, and interior mutability.
Gaussian Wave Packets, Propagators, and the Semiclassical Limit
Free-particle quantum dynamics through wave packets, propagators, stationary phase, and the semiclassical limit.
Cache Lines and Memory Layout
How CPU caches work, why padding exists, and how struct layout changes throughput.
Sparse Set Internals in ECS Frameworks
How sparse sets keep add, remove, lookup, and iteration fast enough for ECS storage.
