As the lockdown measures slowly ease, and we are getting back to some short of normality (at least temporarily), I was kinda reflecting on what I did the last months. I became a dad recently, and I was already 1 month at home on parental leave to help my partner and just the moment that I was supposed to return to the office the German government announced the lockdown and thankfully the company I worked for decided to ask us to work from home, so I am...
ReadJust some thoughts related to monetary rewards as a way to boost employee performance. Have you ever done an activity that you truly enjoyed until someone else wanted to pay you for the work, where you suddendly stopped enjoying the activity? Have you ever got a bonus about something you did, just to see with great dissapointment that the same activity didn't lead to a bonus the next time you performed it? Have your performance dropped after it?
ReadIn the 1st part of the tutorial for creating a CI/CD pipeline for a React app, we saw how to create docker containers for dev, testing and production enviroments. In this 2nd part we will see how to integrate a CI service like Travis CI and deploy our app to AWS.

ReadHooks have released a few months ago and the community is still playing around with them and tries to find the best patterns. At this point it doesn't seem to be one single best solution on how to completely replace state management libs, both in terms of code but also in terms of folder/file structure in the project, so here I am mostly document my journey into that process, and what works best for me.
ReadMost of the times as software engineers we are getting requirements that describe the functional scope of a feature. The tickets that we are working on usually look something like: _As user I want to be able to create an account by entering a name and an optional address so that I can start playing the game_. The ticket do not describe the non-functional requirements of the feature. For example, it is a completely different experience if the user is able to type her name quickly versus facing some short of lag:
