Rule of least surprise
Rule of Least Surprise says: anything ( some it system in our case) should behave in the way that causes the least surprise to people, users, us. We all love suprises we feel good about… not the biggest fans abotu those bad or negative experiences. Surprise creates confusion, bugs, and lost trust. Prefer predictability over cleverness. Think about it… when you call a function, you expect it to do what it says, not sneak in extra behavior. Silent mutations are a classic trap. Side effects are unknown to the user. Trust me, the user will NOT FIGURE IT OUT. Passing an object and having it changed behind your back. Magic…

Another clean code bullet points to remember
Some thoughts after reading a lot of stuff lately and working on totally diferent things. It is just another clean code bullet points compilation to remember or recall every know and then. I know that nobody is capable to remember about all of it all the time. God knows it cannot implemented anyways. I love how people dance cause inventing 3 layers of abstraction to avoid simplicity 🙂 Let us remember the most noble truth of them all… Common sense… Like a brain, remember to use it.

Estimations in sprints are ludicrous ?
Estimations in sprints are ludicrous ? We switched from fibonacci complexity to just plain man day. Estimating work in sprints has become a cornerstone of Agile | Scrum methodologies More and more evidence suggests it often creates more problems than it solves. On the other hand it is a nice “form” You can wrap Your work into. It is a nice template. Teams routinely face mismatches between predicted complexity and actual time investment. Exacerbated by meetings that should be an email, administrative overhead and tasks like code reviews. The Fallacy of Sprint Estimation is why complexity metrics miss but do we have anything better ? The complexity is time disconnected…

Lauers Law – why less code is better
Lauers Law – why less code is better as a very solid idea. Just remind Yourself about all those DTOs that could be a simpler one with a mapper or a dedicated if-else-tree somewhere around data transformation. It challenges developers to prioritize efficiency and elegance in their coding practices, ultimately leading to cleaner, easier to understand and more maintainable systems. The Essence of Lauer’s Law At its core, Lauer’s Law emphasizes that reducing the amount of code can lead to better outcomes. The principle suggests that if developers had twice as much time, they could create a system with half the code while maintaining or improving its quality. The idea…

Locality of Behaviour
Locality of Behaviour is a great principle that should help with maintaining the code. This is the characteristic of the code that enables a developer to only read a small portion of code to understand its function. Without the need to skip, skim, read, jump all over multiple files. I love that rule cause it DOES MAKE SENSE. I can see many places where we would benefit from it but not always do it that way because of the ‘standard’. Which, in the end, nobody knows what it is anymore cause everyone is mixing patterns, antipatterns and the number one performance metric is how fast you can deliver… maybe i…
