It’s pretty funny to me when you think that you know some programming language quite well and suddenly you find out some feature, you’ve never heard before. I mean at all. That’s exactly what happened to me yesterday. Let’s see what’s that. Generics are very useful in programming since we can avoid writing similar code multiple times. But when we start to complicate them too much, it quickly reduces the legibility of the code. Of course, I don’t claim that whe...

Recently, I've been working on the task that can be summed up as: Take this ugly code and do something with it. i.e. more or less the refactoring task...

Tworzenie puli obiektów to częsta praktyka stosowana w bibliotekach serializujących. We wpisie sprawdzam, czy używanie takiego podejścia dla małego bloku pamięci jest efektywne i czy nie lepiej użyć niskopoziomowego słowa kluczowego stackalloc.

You are probably familiar with Uncle Bob’s classic: Clean Code. While Clean Code is about good engineering practices, and writing good code, The Clean Coder is more about communication aspect of developer’s work. It’s about how to behave professionally, be disciplined, and stick to good coding practices. What’s more, it demonstrates how to avoid common pitfalls in software development process. Such as underestimating time, undergo management pressure ...
