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...

In one of my previous post, we got familiar with the graph databases concept as the opposing approach to the aggregate-oriented, NoSQL databases. 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. Today’s one starts it and it going to present the way to install Neo4j and later is going to discuss creating simple queries.  Installing Neo4j To start our j...

Imagine the following situation: your job was to add some functionality to the application. You’ve worked on this for last couple days doing N commits. 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. Sounds familiar to you? Don’t worry, you can still move your changes!  The example Let’s say that we started a new project. We’ve ...

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...

A few days ago I showed you how to combine Nancy with Autofac and ASP.NET Core IoC. Today’s post will be related to the security and more precisely JWT authentication. Before moving further, I’d like to mention that below text is going to be the last Nancy-related one (at least for now). In a next couple weeks, we’ll explore the world of graph databases with Neo4j and .NET Core, so I hope you’re as excited as I do 😉  How does JWT authe...

For couple last days, I worked on gifty to catch up a little bit. My primal task was to introduce JWT authentication to my microservices hosted by Nancy. That’s the topic for next post but today, I’ll describe the proper steps to fully integrate Nancy with Autofac and ASP.NET Core since it’s not that obvious (at least wasn’t for me) and took me way to much time to finally do it. So, I hope that this one will help you one way or another.  Installing pa...

Last week, I finally started working on my „Get noticed” project called gifty.

The steps are:Initialize Kestrel wi...

I’m not a big enthusiast of hard-coded values in my apps, mostly because of three things. First, it’s really annoying to change their value if necessary (especially if one is used in many places). Of course, we can use some „find and replace tool” but to be honest I don’t fully trust them. Another thing is that in many cases we have absolutely no idea what do they represent. Let’s say we have the following of code:   PaymentService.Create(or...

Before starting my career I had absolutely no idea about this profession but even though I loved that! Why?

I’m a really big fan of Scott Hanselman and the way he manages his personal/work time. While watching his „soft” talk titled „Scaling Yourself” I was surprised when he described his way of answering some questions coming from all over the world (via email). He said that each of us has a limited number of keystrokes until we die so, it’s such a waste to write a dedicated email with long answer and examples in the code. Why? Because we could optimize that process and share our knowledge with other folks ou...
