A few days ago, I watched an excellent talk by Erik Meijer called „The hacker way„. In a nutshell, he presented an opposite approach to Agile called Hacker Way which is successfully used by Facebook. The idea is very simple – continuous improvement and iteration. Instead of hours of planning and discussing whether something is possible to implement, just try to prototype this because it will probably take less time than plenty different meetings. And what if you’ll fa...

Siemanko W dzisiejszym poście pragnę nieco przybliżyć temat automatycznych testów end2end i pokazać przykładowy teścik. Jak wszyscy pracujący przy webie wiemy, że ostateczne testy wykonują zazwyczaj ludzie klikając myszką i stukając w klawiaturę. Bez względu na fakt pokrycia kodu testami jednostkowymi, które przed r...

W minionym tygodniu miałem przyjemność migracji z .NET Core’a 1.1 do mającego kilka dni wcześniej finalny release .NET Core’a 2.0. Po krótkim obeznaniu się z tematem miałem mieszane uczucia, połowa wpisów opisywała to zadanie jako mission impossible, druga jako przysłowiową bułkę z masłem..

Last night I started working on my new tech presentation which is going to consist mostly on live demos. Because of limited time (which is usually about 50 minutes) and few topics to discuss, I decided to use code snippets in my Visual Studio Code. Thanks to that, I’ll focus more on the „talk flow” rather than my typing which is not so good when I’m stressed.  Creating snippets in VSC Let’s start with creating an example C# snippet just to present the way it works....

Debugging ASP.NET Core apps in Visual Studio Code is not as simple as in „Windows version” but it’s still pretty easy to setup. So if you have ever had some troubles with that, here’s an explanation of the entire process.  Adding configuration Before configuring VSC, you need to install C# extension if you don’t have it yet. I’d say, it’s a must-have for every .NET developer working with Code since it offers lots of features like IntelliSense, useful sni...

Microservices are still pretty popular in our industry since they imply lots of benefits. However working with that kind of architecture might be annoying when it comes to commit the changes using GIT. Why? Simply because in a common approach, each microservice should be put in a separate repository. Therefore, instead of doing your typical „GIT sequence” once, you end up with few terminals where you do pretty much the same job. Fortunately, you can avoid that with no big deal. ...

In my last article, I presented how to run Aurelia unit tests inside Bitbucket pipeline. What’s quite funny (or may be scary for some of you) is that few hours after publishing, Facebook presented to me an add with „great CI tool” called Buddy. Without much thought, I navigated to the project’s site and I felt in love immediately. Why? There’s one reason – it’s dead simple...

Inspired by Piotr’s article I decided to play a little with the Bitbucket as an alternative to the GitHub. The thing that I really like about it, is that there’s no need to use any 3rd part CI tool such as TravisCI since Bitbucket offers its own build pipeline. Of course, I wanted to test it as soon as possible, so I created very simple Aurelia application using its CLI and I pushed my changes. My basic pipeline file (with the *.yml extension) presented as follows:   ...

It’s pretty funny to me when you think that you know some programming language quite well and suddenly you find out some feature, you’ve never heard before. I mean at all. That’s exactly what happened to me yesterday. Let’s see what’s that. Generics are very useful in programming since we can avoid writing similar code multiple times. But when we start to complicate them too much, it quickly reduces the legibility of the code. Of course, I don’t claim that whe...

The end of the May comes and hence the end of „Get Noticed 2017” competition. Therefore, I’m going to do a short summary which will describe things that I’m happy about together with those that I’m not. Obviously, this post also will be the last one in the GN2017 category which contains 16 articles. Wait, what?

What is a random number? Well, even if you have never read any definition, you can still answer that question pretty easy. It’s the unpredictable result of some action like throwing a dice. We just can’t predict what the next number will be. The Lucky shoot is all we’ve got. In a real world, randomness is kind of natural „thing”, but it starts to be more complicated when it comes to machines. Why? Simply because of their deterministic character...

Today’s post is going to be super easy, especially if you’re familiar with SQL, so without much explanation let’s discuss a little bit about two clauses that you might spot later in my Neo4j & Cypher series – Union and With.  UNION clause The Union clause can be used to merge the results of two queries. There are just two restrictions:the number of columns in both queries must be the samecolumn names in both queries must be the same Let’s demonstra...

As I’ve mentioned in previous posts about Akka.NET, everything that actor knows is stored in memory. While we can skip any database or IO related bottlenecks because things in memory are generally speaking very fast, we must remember that memory is not a place where you can store your data for an extended period of time and keep it. So let’s talk about persisting it.

In the previous post, we explored Neo4j dataset containing actors and movies. We also got familiar with basics of Cypher – declarative query language created for graph databases. In today’s post, we’ll find out how to create a more complex query which will consist of many relationships and nodes.  What are we going to retrieve? Let’s start with defining our task. Imagine that someone asked us to build a query which will answer the below question: I...

As I promised back then, there’s going to be a series of post dedicated to the query language designed for querying that kind of data structure called Cypher.

When the job is over you want to push your changes to the origin but soon after you spot that for the whole time you’ve worked on master/develop branch instead of the feature branch.

Almost all my career I’ve spent with relational databases (later called RDB) and more precisely SQL Server. Honestly, I’ve never complained about that. It works fine, integrating with object languages is very quick since we’ve got a lot of different ORMs (like Entity Framework or Dapper) and it’s pretty easy to learn no matter how advanced developer you are. Sounds like a perfect solution, right? I mean, think about all the companies and projects th...
