What's on tap? And stay hydrated!

Recently when I was experimenting with Spark and Scala I encountered two patterns that I liked; Tap and Hydrate. So I decided to add them to the toolbox as LINQ extensions.

Who writes acceptance criteria?

In the past I've seen two different approaches to user story acceptance criteria writing. My current team introduced a new variant I like. And it is related to how the military works.

Going swimming with kids in the US

Several years ago Eminem was interviewed by a Swedish journalist for a TV show targeting teens in Sweden. Eminem accidentally said fuck. Immediately he stopped playing cool and apologized like a little kid for using the f-word. The interviewer just laughed ans said he could say whatever he wanted on Swedish TV.

Testing with fakes or stubs? That is the question!

I like testing with stubs. But once in a while I encounter people that rather use fakes. And that is a pattern I try to avoid.

The perfect cover letter

Recently a friend of mine applied for a new job. Since he did not know anybody at the company he realized he needed a good cover letter to get through the first filtering and get the recruiter's attention. And so he did...

IoC - good, bad and ugly

I was reading this article that is doing a pretty good job at explaining in what situations an IoC container saves the day. And even though I dislike most uses of IoC containers I've seen I have found them useful once or twice.

Appreciating garbage

I once was working with a company that complained that my code was not optimized because it used 100% of the CPU. So I asked if the user interface was responsive. And it was. So I asked if they experienced any noticeable delays in responses. They didn't. So I asked for how long the CPU was at 100%. And the answer was...
