D-Bus, gRPC, and MQTT can all move information, but they solve different communication problems. The short version: Use D-Bus for structured communication between processes on the same Linux machine.https://toorun.dev/posts/c4-model-software-architecture-diagrams/Fri, 02 Oct 2026 00:00:00 +0000https://toorun.dev/posts/c4-model-software-architecture-diagrams/The C4 Model: A Practical Guide to Software Architecture Diagrams Architecture discussions often start with boxes and arrows, then stall because nobody knows what the boxes represent. Are they teams, services, processes, or source-code modules? The C4 model gives software teams a simple way to describe architecture at different levels of detail. This guide explains what it is, when it helps, and how to make a small example with a free tool.
