Running CUDA on Windows Subsystem for Linux (WSL)
Running CUDA on the Windows Subsystem for Linux (WSL) is not a trivial task seeing that it requires the GPU to be available on a Virtual Machine. In this article I go in more detail how you can get your GPU working in WSL through something NVIDIA calls "Paravirtualization"

Setting up Stable Baselines with Python 3.7 and WSL 2
I've been playing around a bit with Stable Baselines lately for an upcoming project. However while playing, I encountered some issues seeing that Stable Baselines currently requires Tensorflow <= 1.14 which is only supported through Python < 3.8. Due those difficulties, I thought it would be interesting to share how I set up my personal development environment from scratch to play around with Stable Baselines.

Autonomously Landing a Lunar Lander with an Xbox Controller Robotic Arm - Part 2
In Part 1 I explained you how you can create a Robot Arm that can be mounted on an Xbox controller. In OpenAI Lunar Lander I then continued to see how we are able to train a lunar lander environment to land a lunar lander all by itself with a continuous action space.

Training the Continuous Lunar Lander with Reinforcement Learning, RLLib and PPO
For an upcoming blog post, I would like to have a robotic arm to land a Lunar Lander autonomously. In Part 1 I explained how we can build such a robotic arm already, but now we need to be able to go deeper into how we are able to train an environment in a simulation environment (before deploying it on a physical device).

Autonomously Landing a Lunar Lander with an Xbox Controller Robotic Arm - Part 1
Creating an Xbox Robot Arm is something that I've been wanting to do ever since I saw the post by Kevin Drouglazet who was able to utilize an Xbox Controller with an arm he created and was so friendly to publish the design files for (I am definitely not a hardware designer ๐ ) - thanks for that Kevin!

Getting Xbox Controller inputs through Node.js
For an upcoming Blog Post I wanted to connect my Xbox controller and start reading the input values through a simple node.js script that I could send back to an Arduino Nano. This entire process however seemed to be quite "interesting" to find suitable libraries and long-term supported solutions.

Digital Twins - Creating an Open-Source Platform
In a previous blog post I introduced the concept of creating a Digital Twin representation utilizing Dapr's Virtual Actors. Now, this was a theoretical post on how feasible this could be. Of course anything theoretical should also be put in practice, which is what I have been doing this weekend ๐.

A Multi-Language Reinforcement Learning Digital Twin Environment
One of the ideas I have been playing around with the last couple of months is the combination of Digital Twins and Reinforcement Learning. This is an experimental idea where I would love to hear your opinions about it (feel free to comment below, send me an email or reach out to me on Social Media such as Twitter / LinkedIn), and that will be refined over the coming months.

Internet Of Things - Digital Twins Explained
Looking at the history in manufacturing, we saw that many manufacturing companies were deploying statistical models on-edge (e.g. based on parameters such as temperature, pressure and speed, do we send an alert or not), having the main impact on their production volume. If they can then squeeze out this extra bit of improvement, they would thus be able to optimize this process and have a growth in production volume (and net earnings accompanied with it).

Revamping my Blog with NextJS (2020)
Due to the current COVID crisis I had some time to start revamping my blog, focusing on achieving features that were not possible before. All while still keeping the costs to a minimum (or even free). Here I would like to explain how I achieved just this, with the focus on adding the following features:

Sampling a real-time stream
A common problem when working with real-time streams is that you are unaware of the data going in there due to the vast amount of systems connected to it and producing data. Therefor it is interesting to be able to "sample" a stream, where you will connect to the stream with your credentials, wait till an event comes in and then end the connection.

Building a Minecraft Puppet Scanner with Event Hub, a NFC 522 Reader and a Raspberry PI
In Belgium we every year celebrate the coming of "Sinterklaas" on the 6th of December, a celebration for children where this mythologic figure delivers presents for all the children that behaved well that year. (see: https://en.wikipedia.org/wiki/Sinterklaas for more information). To follow this tradition, many companies hold internal events where children of the employees are invited to participate in all kinds of events. I was asked to participate in one of these events and come up with a workshop for children of all ranges - being divided in 2 groups (the very young ones, and the somewhat older ones).

Creating a throttled REST API Consumer
A common thing in Node.js is to create a REST API consumer that will perform a REST call. Due to the rise of many REST APIs, you might find yourself in the situation that you want to execute 1000s of calls (for example: Azure Cognitive Services).

How To Bind C++ Code with Dotnet Core
While you are working with compiled code, you often find yourself in the situation that every bit of performance count (just think about GPU intensive operations or even game engines). For this reason, we often turn back to coding C++ coding to be as low-level as possible (seeing that writing pure ASM is just too hard).

Dividing numbers into equal buckets or bins through Bucketization
A common practice in Reinforcement Learning is to go from a continuous space towards a discrete space. What does this mean? Take for example a range of numbers between $]-3, 3[$, if we want to represent all the numbers that fit in this range as a state then we would have $\infty$ numbers being represented or $\infty$ states.

Getting started with DotNet Core
I wanted to get started with Machine Learning, but rather than using Tensorflow, I wanted to take a different approach and use ML.NET. Now you might ask yourself: "Why use .NET if you have something such as Tensorflow in Python?". Well, my preference goes towards languages containing brackets (C#, JS, ...) rather than having pure identations (Python), making me want to try .NET Core for this.

Finding smallest and biggest number multithreaded in C++
The goal of this exercise is to create a program that generates a table with random elements in it. Once we created this table we have to start 2 threads. 1 thread will find the biggest number and the other will find the smallest number. We will then send this to a result and print these 2 numbers.

Max number with pipes in C++ and Unix
Let's say we have x children, these x children all generate a number and give this to the parent. The parent now finds the highest number and sends the children the process id of the winning child. If the winning child recognises itself then it prints that it is the winner, else they print the winning process id.

SQL - Part 4 - JOIN + Simulating Functions
When creating JOIN queries in SQL we have to realize that we are going to combine every result from the result set with the result set itself. This means that we are going to create a new result set that is the size of the power of 2 of our original result set. (So if we have 1468 records, and we join it with itself, then we will get 2155024 records = 1468^2)
