Single Responsibility Principle (SOLID 1/6)

Single responsibility principle (SRP) is a good way to write better code that is easier to maintain and read. In this blog post I have written what is SRP and why you should write code applying SRP. This is the first blog post from SOLID serie. Reason to write this serie was to deeply learn what SOLID is and master it.

Software Design X-Rays by Adam Tornhill

This is a book about how to detect bad code from code base with the help of code's history from git. I was surprised how simple things and techniques book uncovered about code quality. The key point is the time. We shouldn't do just static analysis from our current code but analyze how our code has lived and progressed. Tornhill calls this behavioral code analysis. I will explain some interesting things from the book, like hotspot analysis and what are surprises in code and why they can be really expensive. After reading the book I understood how to improve code quality cost-effectively.

Always Write Unit Tests

Unit tests are my passion. I always write them and I also encourage others to write them and even have taught developers to write unit tests. But I am quite surprised how often developers don't write unit tests. There is a lot of benefits for writing unit tests. In this blog post, I will explain three main reasons why every developer should always write unit tests.

Code Review Best Practices For Reviewers (Code Review 3/3)

This is the third and last part of my code review related blog post series. Reviewing code is an important task where you can give feedback to the programmer. If you do it right, the programmer can learn something and code quality will be better. In this blog post I wrote how you can review the code better and more effectively.

Code Review Best Practices For Authors (Code Review 2/3)

Why You Should Do Code Reviews? (Code Review 1/3)

Code reviews are something I really value high. In my opinion, every software development team should do code reviews. In brief, the reason is learning and sharing knowledge and code quality. In this blog post, I will explain why.
