Why Go’s range Loop Can Slow You Down with Large Structs—and How to Fix It

In Go, using a range loop on slices of large structs implicitly copies each element, leading to significant performance loss, and modifying the loop variable does not affect the original slice; this article explains the copying behavior, benchmarks three loop styles, and offers practical guidelines to write fast and correct code.

The Semantics of nil in Swift

The article explains that Swift’s nil differs from Objective‑C’s null pointer by representing ‘no value’ for any type through optionals, details how various optionals (Bool?, String?, class?, enum?) are encoded in memory, shows the extra byte cost for Int?, and advises minimizing optional Int fields in structs, using 0 when appropriate.
