Why I Reach for DuckDB When Reading Parquet from Swift or Zig

What an oversized iOS binary, a Linux linker error, and a SQL boundary teach about embedding DuckDB as the Parquet reader for languages without a mature native library.

Outcome: Reader can decide when DuckDB is the right Parquet path for a Swift or Zig project, configure the SPM and build.zig integrations correctly the first time, and avoid the binary-size and linker failures that the unconfigured path produces.

State Machines in Go, Elixir, Swift, and Zig

Why a Go retry loop ran forever because the attempt counter lived on the loop instead of the state, and what the runtime guarantees of Elixir, Swift, and Zig change about which state-machine idioms are honest in each.

Outcome: Reader can pick the right state-machine idiom for their language by recognizing which runtime guarantees the language ships, distinguish a true finite-state machine from unidirectional data flow, and avoid the cross-language mistake of treating one language's idiom as the universal pattern.
