Creatures with an innate need to solve problems, like octopuses and software developers, will look for problems to solve. Invite the development team to be a part of solving the business problems, and provide octopuses in captivity with puzzle boxes.

The glyphs in the latin alphabet are based on shapes that we evolved to recognize, not the figures our hands evolved to draw. Code should also always be easier to read than it was to write.

It is not always possible to write pure functions. Still, the properties of pure functions can help us write testable code.

Don't let frameworks interlace with the domain code. Keep them separate and working with the codebase won't require super powers.

Unit tests are the playground where code learns to behave. If the code is both easy to test and easy to use, it has shown to be reusable.

Design the code so that as little as possible needs to change when the world changes.

Conditionals in the code can come from rules in the domain, or from how we constructed the solution. Make sure to know the differance.

Verbose and descriptive naming can be ugly, but if the code is messy it is better to show that in the names. Then the names can be a tool for further re-design.

What does too many stakeholders do to a piece of code?

Ensemble programming does with developers what the machine learning model random forest does with decision trees. The combination is far better than the parts, if independent enough.

It is easy to forget what you once did not know. Be kind to new developers and create an environment for learning.

This is a meta text about how this site is build using Jekyll.

Learning to refactor instead of rewriting preserves the domain knowledge build into the old codebase while it can keep making money. The skill of continuous improvement is important for developers, and might be neglected in a "rewrite" culture.

Being good at things nobody should ever have to do is a tricky thing. This is a text about wishing for a better world, also when you don't yet have the skills needed to perform well in that world.

Get the benefits from abstractions by turning each signature into a curiosity barrier. When looking at the signature, a developer should know what the piece of code does, without needing to read the implementation.

Languages and frameworks will be part of a larger context. Consider the existing environment when choosing a language or framework.

Code never written, code never read, code never changed and code telling a story

A cognitive tool in shape of a list of things that often go wrong when writing code. Nice to have when you get stuck.

We have to practise new skills in a setting where everything else is easy. Getting to a point where the sustainable way to write software is done by reflex, also on the easier tasks.

Test Driven Development (and unit testing in general) is easier when some things are avoided or encapsulated. Here are four problems faced when unit testing and their solutoins.

A list of aspects to consider when getting to know a new software project and assessing how easy it will be to work with.

Our mind also has ergonomics. Software interior design is about designing our code, and our systems around it, to make our work easier.

Three benefits from doing test first, one test at the time are: specific feedback, design guidance and finding the right amount of tests.

How Theory of Constraints leads us to move the verification step in front of the production step, and keep shrinking the batch size.

In test driven development the tests, even before they even test something, guides our steps. The trick is to take really small steps, and let code and tests evolve together.

When you fear the codebase it creates the code smells of 'Braces, belt and duct tape' and 'Every line has to be read'. Use common design principles to build trust in the code again.

This text has one reason to exist. I want you to write smaller and simpler units of code. I want each unit of code to have only one reason to exist.

Use a linter for your code! And fix all(!) errors and warnings. Your brain will thank you.
