When coding prowess takes center stage, you get fired. — “The graveyards are full of indispensable persons.” — Charles de Gaulle My dad told me this quote when I was 14 years old. It shaped my mindset more than any other quote ever did. It’s a humbling statement that serves to ground us, reminding us that no matter how significant…

The less code we write, the less we will have to refactor, the less we will have to read, and the less will have to test. — I found the way we can write bug-free code: just don’t write anything. Jokes aside, we are a special breed, developers. We are paid big bucks for work that only other developers can truly understand. If this is the case, then why do we write so much? The more we…

Any fool can write code that a computer can understand. Good programmers write code that humans can understand -Martin Fowler — Programming languages are abstractions for humans. It doesn’t matter if you write code in C, Java, Python, or assembly. They are all for humans. If humans were able to understand and write strings of “0” and “1” as fast as a computer, then we wouldn’t need programming languages.

Or the check that the other SOLID principles were applied. — No, it doesn’t mean that dependencies should be inverted. The principle states that there should be no direct link between your low-level and high-level modules. In practice, the principle is the easiest of the five and Think about a car. What if a steering wheel was connected directly to the…

How granularity will improve your code resilience to changing requirements in real-world applications. — Both images above are formed from the same number of pixels, but while one looks like a bear, the other one looks more like a shocked square. It is not a difference of quantity, but one of granularity. It is easier to compose something with smaller pieces. The same logic…

Or when to extend a base class and when to compose objects. — And the number one spot for the most overlooked SOLID principle goes to… Liskov substitution. No surprises here. I’m not going to bore you with the scientific definition. In short, the principle states that all object types should be substitutable for their subtypes without changing the correct behavior. The key…

Specialize in a niche to make money. Step outside it to get the wallet to hold them. — In 1955 Raymond Kroc, a mixer salesman, opened his first franchised McDonald restaurant. He was 53 years old.
