A tutorial on how to use the Messenger component of Symfony 4 with RabbitMQ

Running tasks asynchronous is becoming vital for any large web application. An example, on which I worked, is a Facebook-like activity stream for Open Social (Drupal 8). Imagine that a personal notification based on a relation, rank, and gender has to be generated for millions of users when an event happens. Pretty complex right? Now, imagine the messages to have to be aggregated (e.g., messages like there are 5 new comments on your posts). It Read more…

A realistic plan to pay for a universal basic income in the Netherlands

Een Nederlandse versie kan je hier vinden The idea of a universal basic income (UBI) is gaining traction on the whole political sphere.

How to build a Symfony 4 API Platform application from scratch

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

My thoughts on the Google Adwords API and how to get to your first API call

tl;dr: Do NOT USE the Google Adwords API but the Google Ads API when you build your first integration. The world is a better place because Google connected us faster and more user friendlier to the internet than other options. However, as the company matured the output of the innovation efforts have stagnated. For example, the self-driving car efforts of Waymo (now part of Alphabet), which started testing since 2009, have been caught up by Read more…

Een realistisch plan om een basisinkomen te betalen in Nederland

Vertaling van het originele artikel wat in Engels geschreven was. Het idee van een universeel basisinkomen is populair aan het worden aan beide kanten van het politieke spectrum. Vooral in de Verenigde staten is er een discussie aan de gang welke wordt gevoed door voorlopers van de innovatie zoals Elon Musk en Mark Zuckerberg.
