Just do it! Work on your certifications.

If you asked me 5 years ago if I would do any Microsoft exam, I would have told you that getting certified is something that you need to do at the start of your career. Besides that I would have told you that once your work experience and technical influence increases, you can rely on your seniority. I have to admit that for a long time I could get away with using the correct buzzwords at the correct moment supported by a certain arrogance. Continue reading

Over-The-Air device update - IoT with C#

2022-08-01 10 min read development Bas van de Sande
Developing solutions for IoT devices can be a challenging task, this can also apply for getting a device at its final destination in order to do its job. When time passes by, it is likely that either requirements or conditions are changing and that the device is not capable anymore of doing its job. In other words, it needs to be updated. This is where the real problems may start. In many cases devices are not physically accessible or there are simply too many devices in the field to do manual updates. Continue reading

Techorama Antwerp 2022, human connection

2022-05-26 5 min read general Bas van de Sande
Techorama is a conference that has long been on my list of conferences to attend, but for some reason I never went. Looking back I think I had this idea that world class conferences could only be held in the US (or in a place far-far away from home) with thousands of visitors. I was dead wrong. What the organizers understood perfectly is that in order to have a world class conference, you should offer the same smooth, convenient and rich experience with the very best speakers, but then at a smaller scale.

Register ESP32 to DPS & IoT hub - IoT with C#

2022-04-28 4 min read development Bas van de Sande
In my previous post I flashed my ESP32 with the nanoframework.net, allowing me to write C# code in Visual Studio with all bells and whistles. As life goes… the device landed in my drawer until this week where I had some time to experiment. This time I wanted to hook up the device to Azure IoT hub using the Device Provisioning Service (DPS) which brings me one step closer to my goal, performing device updates over-the-air… Continue reading

From 0 to 100 in 30 minutes - IoT with C#

2022-03-15 4 min read development Bas van de Sande
My interest for the Internet of Things (IoT) was sparked many moons ago, way before the name was born. Back in the days I wrote software for PalmOS devices, and I was intrigued by having raw processor power in my Pocket. Don’t get me wrong, back then we where talking Megahertz instead of Gigahertz and Kilobyte instead of Gigabyte. Having such limitations in processing power and memory tickled my creativity. When I had the opportunity to control hardware (gps, electronic locks etc) using the little devices I was sold. Continue reading

Running a persistent SQL Server in Docker

2022-03-05 3 min read development Bas van de Sande
In IT we always want to work with the latest and greatest, it’s in our DNA to explore new technologies. From time-to-time you get confronted with legacy technologies, robust but boring. One of such things is a piece of software I wrote more than 15 years ago for a friend. It was an application using a SQL Server database that controlled a couple of weighing terminals connected over RS232. Controlling machines is every geek’s dream. Continue reading

Note to self: localhost in kestrel is localhost

2022-02-23 3 min read technical Bas van de Sande
In one of the projects I’m involved in, I ran into a problem. In this project we are building a solution that is running on a Linux based Edge Device connected to Azure. On the Edge device, a k3s cluster hosts a number of services required by the solution. In order to be able to develop and debug on a Linux environment, I equiped my system with Hyper-V, an internal NAT switch and a fresh copy of Ubuntu. Continue reading
