I like to work with git on the command line. But in some cases I prefer UI support. For example, solving merge conflicts is such a case. Git has a command mergetool, which can open a graphical tool to solve merge conflicts. But before you can use this command, you had to configure it. In this blog post I’d like ...

Object Oriented Programming (OOPS or OOPS for Object Oriented Programming System) is the most widely used programming paradigm today. While most of the popular programming languages are multi-paradigm, the support to object-oriented programming is fundamental for large projects. Of course OOP has its share of critics.

You have to change some elements, and retain others, as you redefine the context. Being outcome driven, is one element you must retain – or even elevate in importance, or you fundamentally break the system of delivery Getting Faster at Building ...

Here in Berlin, there are now two meetups dedicated to bots, and they piqued my ...

In this post I am going to explain how you can deploy ...

When I ask people to define what they mean by scaling agile, they talk about these possibilities: They have agile developers. They want agile testers. This is creating cross-functional agile teams for ...

Yesterday I gave a talk that went through all the aspects of using messages queues. I’ve previously written that “you probably don’t need a message queue” – now the conclusion is a bit more nuanced, but I still stand by the simplicity argument. The talk goes through the various benefits and use cases of using message queues, and discusses alternatives ...
