  • Only two rules

    There are only two hard rules when doing code review with your coworkers:

    1. Keep it professional. Don’t. Get. Personal.
    2. Don’t take it personal.

    Remember that you are talking about letters and symbols in files. Nothing more and nothing less.
    You are doing this to improve the results, the software.

    You are not your code!

  • Indentation as a Complexity Metric

    If you want to measure the complexity of your software, there is a lot of software, tools and software-as-a-service offerings available. These options can seem daunting and have a lot of onboarding time (the time it takes you to understand how to use them and get meaningful results).

    If none of these things work for you, don’t despair. There is a simple way to get a high-level view on the complexity of your software. And it’s language-agnostic. It doesn’t care whether you write CSS, Ruby, Java or something else.

  • Show your work

    I wanted to add something to the topic from two days ago: Quality in the eyes of your users.

    There is a thing I did not mention. A practice that could help you and your team achieve a higher quality of your products:

    1. Show your work early and often.
    2. Improve after receiving feedback.
    3. Repeat from step 1.
  • Interfaces

    In computing, an interface is a shared boundary across which two or more separate components of a computer system exchange information. (Source: Wikipedia.org)

    You develop a web application that has a frontend for the users and a backend for the business logic and the data persistence. (This is a simplification, bear with me for a second.)
    Your frontend accesses the data from the backend through an API that the backend provides. This is the first interface. It’s right there in its name Application Programming Interface. But let’s ignore that one for another second.
    How does your frontend consume the API? Did you wrap the calls to the API in its own class in the frontend?

  • Quality in the eyes of your users

    I bet that most people reading this won’t have UAT or QA. So what could you do to still achieve quality in the eyes of your users?

    Yours users will spend more time with your software, like it and recommend it more, when they are happy using it. If we’re honest it might even be enough to make them not dislike the software. There is so much crap software out there, that people use to get their job done, that the bar is pretty low.

  • Two views on quality

    During the last months I wrote a lot about quality and how to develop high-quality software. These letters dealt with topics like linting your code, testing and documenting it.
    I also wrote about the different perspectives and motives that might exist in your team.

    But there is one view that I omitted more or less: The external view of your customers. They expect to receive and use your software. They expect it to be without bugs and to fulfill the role they “hired it for”.

  • Fundamentals

    I am an expert in writing and working with Ruby and Ruby on Rails. But today I was in a fortunate position to realise something: By now, I am language-agnostic. With one of my current clients, I am working with Node.js and Angular. There’s even some PHP in there. My client knew that I haven’t worked with any of these technologies before. Yet they wanted to have me anyway. Even for a price that was above their initial budget.
