I had an opportunity to speak at the AWS User Groups Wroclaw meeting. Surprisingly many people were interested in this topic (the IoT is a niche, not that popular specialty). I prepared an introduction to the Internet of Things domain covering: secure communication between physical and virtual worlds trust in distributed IoT ecosystem design and development of a sample IoT solution I explained and executed every step required to build the following system:

I had the privilege to speak at the 4Developers conference hosted at the National Stadium in Warsaw/Poland. I presented challenges in the automated management of IoT infrastructure and how to solve them. During my talk, I described the automated integration between connected Devices, Edge Gateways, and the Cloud. I covered various real-life challenges and ways to overcome them. My presentation received great feedback from those who were generous enough to provide it.

Introduction AWS IoT Greengrass is a service that you install on local hardware to analyze data and act on it in real-time. One of Greengrass’s advantages is the ability to remotely manage local applications (called Components). It seems like a great solution for many Internet of Things challenges, but without understanding how it works… Greengrass service might disturb your operations! This is a deep-dive technical post, but the conclusion is the following:

I am a huge fan of the iterative approach to building IoT products and services. I recommend leveraging the OTA (Over the Air) Firmware Upgrades to adjust deployed products to users’ needs. But how can we discover the needs of our users? Whenever I buy something online, I always get an email asking for feedback. Can you guess how many times I provided my opinion? Never. Yet, I expect that users of my IoT solutions would invest their private time to share their feedback with me.

Introduction I had the privilege to speak at the 4developers conference hosted at the National Stadium in Warsaw/Poland. LMtx at 4developers conference From the speaker’s room, I saw the grass preparation on the football field. The National Stadium is a modern facility, and I was shocked by what I saw. Three people were executing the following tasks: switching on/off lamps which provide extra light to the grass cutting the grass It does not make any sense to make people perform that simple tasks.

Disclaimer: I do not have any relation with Tesla. To write this post, I used publicly available information shared by Tesla (mainly from the 2023 Investor Day). This is my personal interpretation of those materials. Buy vs. build mindset Some time ago I created a pool on LinkedIn asking this question: Note: Buy vs. build is a very interesting topic for me. Personally, I am a huge fan of designing and building IoT solutions.
