Part I: WebSockets for Real-Time Web and IoT Applications
Have you ever wanted to display your real-time sensor data on a webpage that can be viewed on any device with a modern web browser? How about a web page that serves as a dashboard for controlling and monitoring your embedded device in real-time? With WebSockets, you can do exactly that! In this article, we will briefly review what a WebSocket is, how it works, its benefits, and dive into a system-monitoring, dashboard-type application tutorial.

MQTT: The Go-To Protocol for Distributed IoT and Tutorial
Imagine you have to deploy a dozen various devices throughout a factory floor. These consist of Linux PCs, low power embedded devices, a mobile phone app, simple sensors, and a remote database. Some devices are connected through Ethernet, while other more remote devices utilize a cell network to occasionally phone home. The problem you now have is, how do I get these devices communicating with each other in real time? MQTT is an ISO standard protocol used to solve this problem.

Detecting Stack Overflows on an Embedded System
Stack overflows can be one of the most difficult bugs to squash. An overflow is often hidden in a cryptic, non-static error state. Sometimes the application runs without issue. Sometimes it may hard fault and reset the hardware without warning. It may be overwriting data unbeknown to application designer. The worst error state is the dreaded heisenbug: an error that seems to vanish when you go looking for the cause.
