„Obsesja stanu” to nowy anty-wzorzec #EventSourcing, z którym postanowiłem się zmierzyć! To jeden z typowych problemów, gdy tkwimy w myśleniu o obecnym stanie, tabelach, zamiast rejestrować wynik operacji biznesowej. Przeczytaj więcej o tym, jak to diagnozować leczyć!

Jakiś czas temu napisałem, że "Czy to się skaluje?" nie jest pytaniem, ale mantrą. Zdałem sobie sprawę, że obecnie skalowanie w dół, może być bardziej krytyczne niż skalowanie w górę(biorąc pod uwage ARM, serverless, edge computing). Przeczytaj więcej w najowszym artykule.

“Knowing anti-patterns is as important as knowing any other patterns. Today I tackled #PropertySourcing. It's one of the most common anti-patterns while starting to implement #EventSourcing. Read more in my latest article!

With the simple tricks, you can make your Docker image less cluttered and build faster. In my recent article, I explained practical patterns on how to do that. I showed real-world samples with .NET and NodeJS applications.

When I started my career, SQL Injection and Cross-Site Scripting were perceived as sophisticated attacks. Mature admins installed MSSQL servers with the Internet turned off, because by default, open to the world was a potential source of the attack. Setting up the firewall wasn’t even a standard. Today we have easier. By using the cloud, many things are warranted. Suppliers protect us from basic break-ins. For instance, they’re blocking DDoS attacks and many other attacks that we don’t even know existed...

This week I decided to back to the basics of Event Sourcing. I explained how to build the current state from events in: - object-oriented style in C# - functional style in TypeScript. This is an essential part of treating events as the source of truth.

🚨 Quite often, to make our code simpler, we're trying to make our code more reusable and generic. I wrote an article with a warning that "generic" does not mean "simple". I did that on the example of #CQRS code evolution. Beware and have a read!

SourceGear.Llama.Swift.Sdk, now available on NuGet, is an MSBuild project SDK for .NET 5 that allows compiling Swift, with support for calling .NET class libraries. This blog entry is a closer look at those features. Reminder: Llama is at the "proof of concept" stage, and is not production ready. In my previous Llama blog entry, I walked through a simplistic implementation of "grep" in both C# and Rust. Let's revisit that sample now in Swift.The .swiftproj file Recall that the project file for the C#...

Today I want to invert the classical pro-agile drawing. Let’s talk about the devaluation of functionality that occurs in Agile projects and the cases when Agile is not enough.

This is next post in my little series on streaming JSON objects (NDJSON) in .NET. This one discusses how to send an async stream with HttpClient.
