All say it will not work...

Snake oil salesman, too cheap, does not work, who is this guy and some more were the responses I got from devs when I was looking for feedback to a side-project of mine from peers.


Handing complexity

I believe one of the most important skills of a dev is indeed handling complexity. And it is becoming even more important as the complexity of our world still rises.

I got that questions a couple of times, so I thought I’d answer it here.

I was chatting with another dev today and he told me a story of wonderful Excel usage. It always amazes me what people dare to maintain with Excel.

The dev who created the adapter worked also on the other parts of the system before. As I joined the company, he basically handed the whole system over to me over a period of a few months, I think.
