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 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!
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.
Creating a Pub/Sub system with 100.000 subscribers and 1 publisher
I decided to do something exciting and challenging for personal growth in my Data & AI area and posed myself the hypothesis: "Can I create a system that with a few publishers but a massive amount of subscribers?" with the constraints of:
Azure IoT Edge Simulator - Easily run and test your IoT Edge application
Building an IoT Edge module is an important step for any IoT Application that requires on-edge processing to not constantly send data towards cloud (for bandwith, latency as well as processing reasons).
Creating an Internet Of Things (IoT) Edge Deployment
The Internet-Of-Things (IoT) is currently in full roll-out around the world and will only grow with the deployment of 5G, enabling new use cases and collecting more data than ever seen before. An important aspect of this is not only managing the data that you collect, but also correctly filtering and reducing the latency that you experience on-premise. It is not accepted that it takes 10 seconds round-trip from a container ship in the middle of the atlantic ocean, if you need a response for every image of a camera feed at 24fps.
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.
Creating an Azure Data Lake Gen 2 File Browser for the Web
While working with Azure Data Lake Gen 2 (ADLS Gen 2), I saw that one common ask from the people around me is to be able to interact with it through a web portal. As Microsoft we offer customers the chance already to utilize a tool called "Azure Storage Explorer" but this is a tool that is only available for on-premise systems. What I want to show here is how to create a web portal that can be used for the following use cases:
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).
Getting Tweets of multiple people on Twitter
For a new project of mine, I wanted to get the different tweets of multiple people at once and save those as a CSV and JSON for further processing. But how can we do this easily in just a couple of lines?
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).
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 Azure Functions
So I wanted to write a function for a customer that would trigger a bot. What I thought would be an easy process, turned out to be a lot of debugging and tuning to get everything working. Which is why I decided to write this post to help others get started with Azure Functions.
Getting AMQP to work in your browser
For one of my customers, I had to be able to connect to an EventHub through the browser, so how did I do this? So we know that EventHub works with the AMQP protocol, so what if we could get this working in the frontend?
