• register-allocation

How copying a small aggregate into local variables exposes Scalar Replacement of Aggregates to LLVM, letting hot loops keep state in registers instead of repeatedly loading and storing through a pointer—illustrated with Zig/Rust reproductions and TigerBeetle's AEGIS-128L speedup.

• design-patterns
• data structure

Shows that data-structure choice must be driven by access pattern, not category: a custom bitset with SBO and virtual-mutation hashing is strongly justified for a hot-path DFS that repeatedly clones, hashes, and probes without committing, while the standard-library DynamicBitSet is the right tool for a simple one-shot debug assertion

• design-patterns
• allocator

A practical reference on Zig allocation patterns - breaking down the aware (unmanaged) vs. owning (managed) ownership models, arenas, index arenas, and other key idioms used in porcupine-zig, with real code examples and tradeoffs

• zig-io

Explains how Zig’s Io gives you most of the engineering wins of effect systems (no function colouring, swappable interpreters) without any type-level tracking — here’s how it stacks up against Scala 3 Caprese and Kyo across the full design spectrum of effects
