Installing Kubernetes on an Nvidia Jetson Cluster

We now have [a beautiful cluster assembled and running](/post/2021/5/30/infrastructure-nvidia-nvidia-jetson-cluster), but no software running on it yet. So let's get started and provision Kubernetes on top of it so we can manage our nodes easier!

Creating an Nvidia Jetson Nano Portable Cluster

[In my previous article](/post/2021/5/30/infrastructure-nvidia-nvidia-jetson-setup) I explained how we can get one single Nvidia Jetson Nano 2GB Node up and running. In this article I would love to go in more detail on how we can create a cluster.

Getting Started with Nvidia Jetson Nano Developer Kit

I recently acquired an Nvidia Jetson Nano 2GB Developer Kit, so I'd love to walk you through my process of getting it up and running!

Decode Base64 with Azure Synapse Analytics its Serverless SQL

I wanted to analyze some data in Azure Synapse Analytics, Serverless SQL. This data was coming in from my IoT Hub that I created and was being routed towards an Azure Data Lake Storage account as small JSON files. However when trying to analyze this data, it appeared that IoT Hub shows the body as Base64 encoded and T-SQL couldn't analyze it.

Creating a Dapr Project with Node.JS and the Dapr-JS SDK

Dapr is simply amazing, allowing you to interact with libraries that otherwise take a couple of hours to implement or even days depending, on your level of comfort with them. Next to that, when you would utilize libraries, you also need to take care of correct authentication, error handling, and more.

Running Dapr on Azure IoT Edge

I've been working on a large-scale project that has some interesting requirements performance wise. While having around 6+ modules, I should get a performance of around 10ms roundtrip! One container does AI inferencing within ~2ms.

Azure Project Bonsai - Physical CartPole Project

In my previous post I revisited the Bonsai platform. Now it's time to actually start preparing to put it into production! (this will become more clearer over time 😉) To start off with a spoiler: Project Bonsai - It's impressive! 😎

The Azure Project Bonsai Platform Revisited

It has been almost an entire year ago since I have visited the Bonsai platform that I covered in my [previous post](/post/2020/5/5/ai-ml-rl-introduction). Since then a lot changed on the platform, so the time has come to revisit it and see in more detail what exactly changed (on the surface of course)!

Schedule Kubernetes CronJob to restart pods automatically

For a project I needed a way to automatically schedule pods to be deleted every 3 hours. This was due to the nature of the project where we wanted a cleanup in memory due to zombie processes appearing. It's not a clean fix, but it was necessary for production to run stable while we were patching things.

Tutorial - Creating an Email Microservice with Typescript and Dapr

Once in a while a new project comes out that I am totally hyped about! [Dapr](https://dapr.io) is such a Project! In this article I would like to go in-depth on how we can quickly (< 10min!!!) create a Microservice that will send an email through a Microservice invocation mechanism!
