Firmware test automation using real embedded devices

In this talk I am going to present my approach on testing embedded firmware that using real hardware, because testing firmware in emulators drastically limits what actually gets tested and it can quickly become very tedious to mock, fake and set up environments for embedded firmware that needs to connect to cloud services. The approach I am showing is going a different route: let the firmware run on real hardware, and test its behavior. I will show how I implemented these tests using Zephyr, and AWS but this solution can be applied in any environment which cannot be run inside a test runner.

Here is how it looks like:

Cloud connectivity and protocols for the Internet of Things

This is a webinar I did for Nordic Semiconductor Tech Webinars together with my colleague Carl Richard Fosse, but it applies to everyone who wants to get an introduction to protocols to consider when developing a cellular IoT product.

It provides an overview over the important factors that need to be considered when it comes to picking the right solution for sending your products' data to the cloud.

Motivating developers with purposeful work

I work at a company where we decide on our own, when how and on what we work; I have full control over my life. We believe that working in a so-called network organization, without central leadership, is the only sensible and sustainable way to run a business. But what does that mean for managers if you no longer can assign work to your team? New skills are required and in this talk I want to give a glimpse into the future of tech-leadership and what is need from you to build a joyful workplace for team.

TDD vs. Velocity: Testing for start-ups and other organizations with fast innovation cycles

These days, when every new project is a start-up, we need to run software that is both robust (because there are customers already using it) and open for change (because we are constantly adding new features). This provides a challenge for applying TDD.

There is no half-remote team

Having remotes on the team enables you to hire for talent and not for availability. From my recent positions I learned that it is critical to encode remote work in every team members work habits-even if they are working on location. This talk highlights the issues that arise when teams or not co-located and how to deal with them.
