Nowa feature C# - Funkcje lokalne, coś na kształt Action i Func ale w naszej metodzie.
Another quick video tutorial from me. Here, we will focus on implementing our own “SDK” responsible for handling the Facebook Graph API using C# and .NET Core (of course you can achieve the same result on the full .NET platform).
I want to get in a good habit of recording some simple tutorials from time to time using the English language, so here comes the first one about my experience with running the SQL Server on Linux. Enjoy! The first thing you need to do is to open the following website and follow the selected installation guide. For example, I’m using the ElementaryOS so I chose the Ubuntu guide. Also, make sure you’ll install the SQL Server Tools. Eventually,...
Posted on by Tomasz Grabusiński ID tokens are used in OpenID Connect to login users into applications. With regards to the OpenID Connect specification the application must validate the ID token in order to ensure the token’s integrity and authenticity.
Dawid Sibiński 0 comments .NET, C# Hello again 🙂 Visibly this is going to be my first technical post here. I hope you’ll find it useful.Windows Services Recently I came up with a need to create an application, which executes some tasks in the background based on file system’s events. “That’s easy”, one would say. “Build Windows Service app”, he would add. Sure, that was also my first idea. I think that’s very common that we want to create an application without any GUI, which pur...
Welcome to the first episode of my course “Becoming a software developer”, which is a starting point for your journey into the software development world. It also begins a first part (there will be 4 parts in total containing 4 episodes each) which is dedicated to the core concepts of object-oriented programming using the C# language.
A few days ago when I posted the information about creating a course Becoming a software developer amongst many positive comments I had received at least a few question why would I do something like this for free. In the video below (English subtitles are available) I do present my answer. And I would also like to write a few additional remarks about it.
Welcome to the first, or actually, the episode number 0 of my first online course ever named “Becoming a software developer”. o what is it all about? The goal is simple – I’ll be acting as a mentor to a friend of mine Patryk Huzarski, who would like to become a software developer.
Tworzenie aplikacji na najświeższą platformę Windows (Universal Windows Platform) nie powinno sprawiać dużych problemów nawet początkującym osobom w tym temacie. Warto jednak już od pierwszych kroków wyposażyć się w ciekawy zbiór bibliotek od Microsoftu, który uprzyjemni pracę w UWP. Zróżnicowany zestaw pomocnych elementów znacznie usprawni programowanie na platformie Windows.
Nowadays, asynchronous programming isn’t something unusual. We all know that when it comes to do some I/O operations or HTTP request, we should do it async. Why? There’re several reasons but two most important are:Efficiency. In many cases, the code might work faster. That’s because it’s not forced to wait for the result. Instead, it can work on some other stuff and then come back for the response when it’s ready. Simple is that.Comfort. Async improves the comfort of using our applications. We don’t blo...
Programowanie współbieżne – jeden z najbardziej zaawansowanych tematów programistycznych. Z jednej strony programowanie równoległe jest już standardem, z którym mają styczność (może w pewnym stopniu nieświadomie) nawet początkujący programiści. Z drugiej strony nadal tylko niewielu programistów potrafi pisać poprawny oraz efektywny kod współbieżny.
It’s been a few months already since I’ve started working for good with distributed systems using (micro)services and asynchronous processing via service bus. Many issues and question raised and one of these was how to not lose the information about commands and events being processed and even more importantly, how to notify the user once the request has completed? I’ve had to come up with some solution that seems to be sufficient (at least for now) and I’d like to share it with you.
Reading time ~4 minutes This post is an analysis of a very interesting optimization proposed by Nicholas Frechette in the comments under the previous post. He proposed to use one of the oldest tricks in performance cookbook - divide and conquer. Well, it did not turn out as I expected.Saga Before I go further here are some link to the previous posts on the problem of calculating similarities and then optimizing. This thread grew to a few post. Here are all of them:How I calculate similariti...
It’s been quite a while since I posted the latest update of the Warden project designed for monitoring the resources in general. After a lot of back-end coding and refactoring, the time has come to finally focus on the new web interface implementation. And this is where the things start to become interesting (I promise).
Visual studio simplifies creating of WCF service by providing project templates. First way to create WCF service is to use the New Web Site option and then choose WCF Service. It will create a new web site with a sample WCF service implementation linked to a .svc file, with related configuration in the web.config file. In this approach Visual Studio does not just create the core WCF project and add the needed assembly references, but it also builds the host application.
