The byte-order fallacy: Rob Pike's post on endianness
Rob Pike's post argues that assuming the native byte order in code often causes portability bugs, especially in C and C++ serialization, and advocates handling endianness explicitly.

What happened and what to do
Rob Pike's post argues that asking what the native byte order of a machine is usually leads to wrong or misguided code, and recommends handling byte order explicitly. The text explains why assuming endianness in serialization code in C and C++ often causes portability bugs when data crosses architectures, networks or files.
In practice, a company can review its serialization modules and binary protocols, defining a fixed byte order for each data format and applying it through explicit read and write functions, instead of implicit conversions via pointer casts. Automated tests across different architectures and header validation in collection pipelines reduce the risk of data being silently corrupted between systems.
How the consultancy can help
Diagnosis of serialization and binary data exchange points, with a proposal for explicit byte order, testing across multiple architectures, and implementation of the fixes in collection and integration modules.
