Answering the question "What's the difference between a command and an event?" is not so obvious as it may seem. Fact vs Intent is not explaining everything. I went through the different aspects of this distinction in my new blog post. I also explain the consequences of those considerations.

A while ago I came across “Quick notes on a rant” authored by Don Syme. This rant criticizes the C# language for the lack of a few important features. The first point is "Implicitly discarding information is so 20th Century" which brings our attention to one of the sources of bugs in C# programs. Lucky me, I got the pleasure to make this kind of bug and find it later in production code, so this blog post is to save you the trouble...

In the last two posts, I’ve described 14 different code smells related to the async/await keywords. Beside the problem description, I’ve also provided info about code analyzers that can detect and report given issue. Those analyzers come from a few different packages that are not strictly devoted to the asynchronous programming area. They also contain rules from other fields with predefined severity, which might not be appropriate to your needs, or you might not be interested in enforcing them at all. Th...

Mocki to zmora wielu osób bo często trzeba napisać sporo „niepotrzebnego” kodu, który czasem (jeśli dobierzemy zły framework) jest zupełnie nieczytelny. Na domiar tego niektórzy używają pojęć mock, stub, fake, dummy. Jak się połapać w tym wszystkim? Co do czego użyć? Jak to wszystko pokonfigurować? I wszystko po to aby przetestować jakąś jedną funkcję… … no właśnie, dlatego nie piszę mocków. Unikam ich jak ognia. No ale jak to nie piszę? Bo jestem leniwy i uważam, że dobry...

Which analyzer package should I use and how to configure it to avoid most common problems related to async/await.

Working with big databases, consisting of many, many tables (like hundreds or thousands), can be really painful. Recently, this happened to me and I discovered 2 lifehacks that help me survive this hard days. Filtering tables You know the struggle when you know a part of a database table name but cannot remember the whole name? How could it be named? BasketPositions, CustomerBasketPositions or maybe PositionsOfBasket? How can you know?! Yeah, it’s the everyday struggle with huge projects! This is...

One day we decided that we don’t want to waste any more time on tasks that can be automated and we decided to start with automation of our merging process. Today’s development teams use various branching models. Ranging from the straightforward ones, such as the trunk-based model, up to a completely autonomous continuous deployment process. Many consider continuous deployment to be a utopia for lar...
