There a various tutorials showing you how to host your web applications with a couple of lines on any hosting solution. But that's it. You are able to host your application somewhere, but there are a lot of open questions. What about using an own domain? What about securing it with SSL? What about hosting multiple applications side by side yet…

After learning about gradient descent in a linear regression , I was curious about using different kinds of hypothesis functions to improve the result of the algorithm itself. So far, the hypothesis function was only a linear straight line. However, your training set may not have a linear correlation and by staying with a linear model it becomes…

Recently, I built my own course platform to teach students and professionals about web development. The courses on the platform are teaching about React and its ecosystem, but I want to generalize the platform's implementation in the future. It should be reusable for for other educational domains too. The platform launch came along with the release…

When I recently started to dive into the topic of machine learning, I had to relearn all the things I have studied about linear algebra, stochastic and calculus at school and university. I took a little refresher on matrix operations (addition, subtraction, multiplication and division) in linear algebra and learned about the different types of…

Recently I started to take the Machine Learning course by Andrew Ng on Coursera. So far, it is a blast and I am so keen to apply all my learnings in math from university. Starting right into web development after university, I never had the opportunity to apply those learnings when implementing web applications. Now, it is refreshing to see use…

MobX is used for state management in modern applications. Often it is applied in a React.js application, but it is not necessarily bound to React. In addition, it is a valuable alternative to Redux as state management solution. If you are using create-react-app as your application boilerplate, you most likely run into the questions of how to…

There is a high likelihood that there are already a multitude of articles about the new React.js 16 release. But for learning about the changes of the library myself, I wanted to read up all the new React 16 features and improvements too. I thought it would be useful if I would share briefly what I have learned along the way. In the next days, I…

I am excited to launch my course The Road to Redux . I worked on the course for the last 6 months and squeezed every of my free minutes during a workweek, weekends and holidays into it. For instance, when writing the book, I woke up two hours earlier before my 9 to 5 job to write ~750 qualitative words a day. It continued by building a platform…

Recently I was confronted with SVG in React. I had to use a logo and wanted to use playful SVG background patterns in React. By using SVG, I avoided to use other image formats which would add performance penalties to my application. The article will guide you through using SVG in React. It shows you how to use plain SVG for your application and how…
