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,...

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, 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.

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...

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.

Kilka słów o tym, że nie zawsze idzie poprawnie wyszpiegować co siedzi w binarce. Czasami kod znacznie odbiega od rzeczywistości i to bez użycia obfuskacji.

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.

Reading time ~1 minute This will be a fast errata to the previous one. This time I will expand the oldest performance mantra: The fastest code is the one that doesn’t execute. Second to that is the one that executes once Last time I’ve forgot to mention one very important optimization. It was one of two steps that allowed me to go from 1530 to 484 seconds in the sample run.Saga Before I go further here are some link to the previous posts on the problem of calculating similarities and then...
