New MS Test SDK to easier setup test project. I didn't even know there are so many extensions. devblogs.microsoft.com/dotnet/introdu…

I was implementing validation function to verify that a number fits into specified round-lot. Or in other words, if dividing 2 numbers gives an integer. And I decided to write few blog posts about it. Here is the first one. duracellko.net/posts/2024/06/…

And here comes my 2nd blog post about round-lot validation. After lot of math previously this post reveals implementation of the validation function. duracellko.net/posts/2024/07/…

Update your System.Text.Json dependencies to at least 8.0.4 now 👇 github.com/advisories/GHS…

And 3rd blog post about round-lot validation is out. This one explains Decimal data type in #dotnet. duracellko.net/posts/2024/07/…

Usual answer to the question "What kinds of problems can quantum computation solve efficiently?" is "It can run computations in parallel." However, I find it inaccurate and misleading. I decided to write a series of blog post to find a better answer. duracellko.net/posts/2025/10/…

Probably almost every developer is familiar with async/await keywords. Surprisingly async/await is with us more than 15 years. It is easy to forget why it came to world. It is actually nice abstraction worth talking about it. duracellko.net/posts/2026/01/…

Quantum computing is not only about computers, but also quantum communication and networks. Today we look at secrecy using quantum cryptography. 📖 Read the full blog post: duracellko.net/posts/2026/01/…

I’ve just published a new deep dive into quantum coin flipping — a fascinating concept that blends randomness, security, and fairness in distributed systems. duracellko.net/posts/2026/01/…
