The Place Where Modern Operations & Technology Come Together
Building an IoT App with InfluxDB Cloud, Python and Flask (Part 3)
Last year I started an IoT project, Plant Buddy. This project entailed soldering some sensors to an Arduino, and teaching that device how to communicate directly with InfluxDB Cloud so that I could monitor those plants. Now I am taking that concept a step further and writing the app for plantbuddy.com. This app will allow users to visualize and create alerts from their uploaded Plant Buddy device data in a custom user experience.
Using Visual Trace Diagnostics on Zephyr Applications
A rehearsal recording by Johan Kraft for his talk at the Zephyr Developer Summit 2021.
Five worthy reads: Internet of Behaviors - Exploring beyond the Internet of Things
Five worthy reads is a regular column on five noteworthy items we’ve discovered while researching trending and timeless topics. This week let’s welcome a new acronym to the club — IoB (Internet of Behaviors) and assess its impact. Organizations are making the best use of analytics, A/B testing, and more amazing things to map the perfect customer journey. Here comes the missing piece to building an ideal user journey: Internet of Behavior (IoB).
How Siemens uses IoT sensor data and Grafana to optimize train maintenance, capacity, and more
There’s something special about the interactions a train journey generates — the interesting views and perspectives that inspire insights and drive new thinking. Martin Klimmek, Head of Digital Development and Operations at Siemens Mobility and Haluk Tutuk, Data Platform Engineer with Periscube, are among 20 data scientists, data engineers, and DevOps engineers building the next generation of data-powered customer service for the rolling stock industry in the U.K. and beyond.
Pocket article: Undefined Behavior Sanitizer Trap on Error
This post is a brief overview on how the Undefined Behavior Sanitizer can be used to trap unintentional or error prone parts of a C program. We’re going to look at how it’s used on a desktop program, as well as a way to use it in small embedded programs!
Tracealyzer Demo and Features
A short demonstration of Percepio Tracealyzer by Dr. Johan Kraft. Tracealyzer is the premier solution for visual trace diagnostics, giving embedded software developers amazing insight into their runtime systems. This allows for easier debugging of system-level issues, finding software design flaws and for measuring software timing and resource usage. Ensure your code is reliable, efficient and responsive. If not, learn why.
GrafanaCONline IoT Day recap: Real-time streaming in Grafana 8, fun DIY projects, Grafana for trains, plants, and more
Week two of GrafanaCONline 2021 is going strong! To catch the live sessions — or to watch all the videos on demand after GrafanaCONline ends on June 17 — register here. If you didn’t get a chance to watch yesterday’s presentations, here’s what you missed from Day 4 of the conference.
How to Debug HardFaults on ARM Cortex-M MCUs
No matter your use case or how sophisticated your hardware is, faults happen on embedded devices all the time for a variety of reasons. Maybe it’s something easy like a reproducible NULL pointer dereference you hit during development or maybe it’s something more subtle like memory corruption or divide by zero faults that only exhibits themselves in zero-g, high temperature, weak magnetic field, or noisy RF environments!
Getting Started with Memfault for MCUs
Memfault recently launched a free self-service portal giving embedded developers instant access to Memfault across Android OS devices or ARM-based microcontroller devices running on bare metal or real-time operating systems (RTOS). In this recorded webinar, you'll learn what Memfault is and how you can use it for device observability at scale.
