How learning happens, and Evidence-Informed Learning Design - New knowledge acquired

When trying to master a new field it is difficult to find the right direction and resources from which to learn. I set out to learn more about the science of learning and teaching in order to create a tool (Naabu) for teachers and researchers. I read a few books [1]; dived into the scientific literature (e.g. Koedinger and Molenaar); and watched videos of online courses (Instructional Design…

Remote development with Docker and Visual Studio Code in a breeze

Remote development with Docker and Visual Studio Code in a breeze

My old setup was a dual boot desktop with Ubuntu 20.04 and Windows 10. Ubuntu is mainly for the great support for development tools like Docker and I used it because my production systems run in Linux. As a gamer and hobby game developer, Windows is a must. Recently, I decided to work in a shared office space and bought a Macbook Air with the new M1 chip. Docker for Mac is supported and the…

Maximize the number of people that are content

An article about morality: Maximize the number of people that are content

For some people, it is important to have an explicit moral compass and have a set of heuristics that can guide you through life. They want to do things that are good and that have meaning. Thinking is hard work and the need for each person to finds their own meaning in life is not practical and can lead to outcomes that are not morally optimal. I hope that publishing my moral compass and thought…

Interreflections a movie review and my thoughts on Peter Joseph - Niels van der Molen #InterReflections #PeterJoseph #RevolutionNow

He is a filmmaker but also the creator of the zeitgeist movement.For better or worse, Peter has played a major influence on the way I look at society. In hindsight, Peter clearly followed the spirit of the times from being an early adopter of the most popular conspiracy theories to being an early critic of the current capitalistic…

Publishing my thesis work - Emotion detection using sentiment analysis

Publishing my thesis work – Emotion detection using sentiment analysis

For my master thesis in “human media interaction” at the University of Twente, I worked on applying sentiment analysis technologies to emotion detection in online communities.

I am proud of this work which took 10 months of programming and writing and I felt it deserved to be digitalized from PDF to HTML. After graduating I also gave a lectureto other HMI students and there was some interest…

Exploring reactivity in Svelte JS with real-world examples #svelte #sveltejs #reactivity

So, we all saw the presentation by Rich Harris, the creator of the Svelte Javascript compiler, and are excited about implementing spreadsheet reactivity in our projects. However, even though the concept is easy to grasp when looking at simple examples implementing reactivity is sometimes not obvious when working with real data.

In the last months, I have worked hard on Wisvidsan online math…

Why can Andrew Yang win the 2020 presidency? #AndrewYang #YangGang

Even though I do come from the Netherlands I am an enthusiastic follower of the presidential elections. Furthermore, when a tech-minded startup guy runs on the platform based on a universal basic income (Freedom dividend) policy it is difficult to not to watch every interview, debate, and rally he conducts.

I first became aware of Andrew Yang from an interview with Sam Harris(unfortunately…

A good authentication example, Sapper sessions, Svelte Store

A good authentication example, #SapperJS sessions, #svelte #sveltejs Stores

For my new architecture with microservices and Svelte, a vital implementation detail is the authentication and authorization mechanisms. In the last article, there was an example of how to build the signup component and in this example, we take a look at sessions. The final result is basic account creation and authentication support with a JWT token for upstream services.

A quick glance at the…

My new web application architecture: A Svelte front-end using API Platform (micro)services

My new web application architecture: A #Svelte front-end using #ApiPlatform (micro)services

For a new project, I decided to upgrade my architecture. My previous architecture ran with single-instance SaaS build in Drupal. Meaning that every new customer would get its own Drupal installation with its own database. As I learn more about APIs with by building services with API Platform the advantages of a big monolithic application like Drupal is diminishing. Currently, I developed the…
