Too much time since I wrote something here. It’s been two years. In the meantime I used more twitter than the blogs now.

A long time since I posted new content. What happened since 2018 ? I finished my mission at Qualcomm Life and started the next one at Ostrum Asset Management. I’m workin on a legacy application. Why did I choose this ? Thing is I’m really fund of DDD (Domain Driven Design). What is DDD ? It’s about modeling with code - whatever the paradigm - a point of view to obtain a correct answer.

I’ve done a BBL version of my DDD introduction talk in Qualcomm Life Paris. This one was very challenging because I had to compress a two hour talk in one hour. I’m looking forward to present it again. The slides are here. Next event, DDDEurope 2019 Amsterdam, as a visitor :).

Inheritance abuses bores me. I’m sorry to tell this, but IT teaching is often responsible.

The course usually say something like this:

When behaviour is used in several classes, then create a root class and put your code in there in a protected method. So all the children classes can reuse the behaviour.

So inheritance is solving the reusability problem.

I learnt to code this way, with a bunch of animals as examples.

I use tests frameworks all the time. Whether I do TDD or try a code sample. It’s the faster way isn’t it ?

I become a “green addict”. I feel unconfortable when I’m not seeing green dots on my test runner - or when I do not see red dots when I change code (which frightens me much more).
