The CRUD Anti-Pattern in REST APIs

Last Update: 24.08.2018. By Jens in Newsletter

Software patterns come and go. As do the anti-patterns. Things you should not do they proved to be bad decisions before. One of the new anti-patterns is the “CRUD Mapping in REST APIs”.
In this pattern, we create an API that represents 1-to-1 our data model and we blindly map our internal data structure to the outside.


Some fun with a legacy app and a lesson I learned

Last Update: 23.08.2018. By Jens in Newsletter

Yeah, this morning I did have some fun with another legacy app. Like the one from the stone age, it is closing 10 years soon. And the guy, solely working on it, wasn’t a proficient dev so to say. He did get the stuff done but lacked a lot and had no real interest in progression. But he was nice :-)

Think like a startup

I think there are many parallels between a startup and a single dev career. We can learn a lot from the startup world and apply it to our own business or career. Take the first step every startup takes. Choosing an audience. The audience is the people actually buy from the startup. Replace buy now with hiring you and you got the career equivalent.


Programming sucks, I quit

Sick of deadlines? Sick of project managers, boss, customers or whatever? Coding was once a dream of yours and now it drags you down. Each time you even think about it? Dreading Mondays? Thinking, why am I doing this shit?


Devs are like moths...

Somehow complexity attracts devs like light attracts moths. They can’t resist, we can’t resist.

How to implement custom parameter mapping in Spring MVC

Last Update: 06.08.2018. By codeboje in Spring MVC | Spring Boot

In this tutorial, we will discuss HandlerMethodArgumentResolver which is being used to resolve the arguments of the public MVC methods (handler methods). To understand this feature in depth, we will look at different out of the box method argument resolvers and how we can a write custom argument resolver. We will take an example of resolving the hostname (domain) of the server.
