Quantum Computing - qubit
When I asked the question, "What makes quantum computation more powerful?" or "What kinds of problems can quantum computation solve efficiently?", the usual answer was, "It can run computations in parallel." While this is perhaps the most accurate single-sentence answer, I find it both inaccurate and misleading. A few years ago, I began my journey studying quantum computing. My background is in computer science, so my main interest was to understand the problem space that can be solved more efficiently by quantum computation. I did not study physics beyond high school, and my goal was not to delve deeply into quantum physics. In the next few blog posts, I will attempt to provide a better explanation to the question, "What kinds of problems can quantum computation solve efficiently?"
Window icon in WinUI 3
When developing a Windows application using WinUI 3, by default it displays default Windows icon in taskbar: 
Changing this icon is a little bit more complicated than in other .NET UI frameworks. In WinForms and WPF Window class has Icon property. And these frameworks have classes to work with icon objects. Universal Windows Platform application doesn't have window under control and the platform automatically sets the icon from application assets.
Round-lot validation (part 4)
In my previous blog post I was writing about round-lot validation on data type decimal in .NET. I presented that the implementation using simple division of the numbers does not return any false-negatives. It means that the function never returns false, when a value fits into a round lot. However, it can return false-positives. It means that the function may return true, when the value doesn't fit into the round-lot. I also presented a small update to mitigate false-positives, but we didn't eliminate them completely.
Round-lot validation (part 3)
Recently I was implementing a validation checking that a number entered by user fits into a configured round-lot. And I decided to write few blog posts about it. In the previous post I presented implementation of the function for data type double. And in this post I will focus on decimal data type.
Round-lot validation (part 2)
Recently I was implementing a validation checking that a number entered by user fits into a configured round-lot. And I decided to write few blog posts about it. In the previous post I described the problem and created naive implementation that didn't work in some cases. And I presented implementation that should handle those cases, but there is unanswered question about acceptedError.
Round-lot validation (part 1)
Recently I was implementing a validation checking that a number entered by user fits into a configured round-lot. For example when the round-lot is 2 then only even numbers are allowed values. Other examples would be:
Hosting both Blazor Server and WebAssembly in single website
Blazor framework supports 2 types of hosting and running of Blazor application. Blazor Server runs application on server inside ASP.NET Core application and only exchanges HTML fragments and events with client. And Blazor WebAssembly runs application completely inside web browser and in some cases does not need server at all. What if you want to use both models in the same application and run different type based on client device type.
Configure Blazor app from server
Microsoft recently release Blazor WebAssembly 3.2.0 Release Candidate. This version includes configuration of an application by appsettings.json configuration file.
Create certificate for automated build of UWP app
Visual Studio 2019 improved build of UWP applications for Windows 10. Good news is that it is possible to build the project without need for temporary certificate. This is useful for automated builds validating pull requests. When validating pull-request, I simply build the project without creating APPX package. In Visual Studio 2017 this used to fail because of missing certificate to sign the package. So I had to create a self-signed certificate. However, in Visual Studio 2019 no APPX package signing is done by default, and thus no certificate is needed.
Blazor and .NET Core 3.1.1
Few days ago updated version of .NET Core 3.1.1 was released. It includes several security fixes, so it is strongly recommend to upgrade. However, after installation I was not able to build Blazor projects with client-side Blazor. Build failed with error:
