Why is it valuable to get into the Qrator Labs partnership program?

In Qrator Labs, we firmly believe that working together brings a better result. Which is the reason why, for years, we were trying to find meaningful partnerships with all kinds of companies. They either seek to provide their existing customers with the top-notch DDoS mitigation technology developed at Qrator Labs with many additional ecosystem solutions or want to succeed the other way around. By getting their product available for Qrator Labs' customers by integrating into the Qrator anycast filtering network.

I’ll be honest: I don’t write in pure C that often anymore and I haven’t been following the language’s development for a long time. However, two unexpected things happened recently: С won back the title of the most popular programming language according to TIOBE, and the first truly interesting book in years on this language was published. So, I decided to spend a few evenings studying material on C2x, the future version of C.

Here I will share with you what I consider to be its most interesting new features.

Starting from .NET Core 2.0 and .NET Framework 4.5 we can use new data types: Span and Memory. To use them, you just need to install the System.Memory nuget package:

PM> Install-Package System.Memory

These data types are notable because the CLR team has done a great job to implement their special support inside the code of .NET Core 2.1+ JIT compiler by embedding these data types right into the core. What kind of data types are these and why are they worth a whole chapter?

If we talk about problems that made these types appear, I should name three of them. The first one is unmanaged code.

Both the language and the platform have existed for many years along with means to work with unmanaged code. So, why release another API to work with unmanaged code if the former basically existed for many years? To answer this question, we should understand what we lacked before.

This chapter was translated from Russian jointly by author and by professional translators. You can help us with translation from Russian or English into any other language, primarily into Chinese or German.

Also, if you want thank us, the best way you can do that is to give us a star on github or to fork repository github/sidristij/dotnetbook.

If someone of you has tried create angular libraries, he may face the issue with lazy loading Feature Module from node_modules. Let's dive deeper and go thru the dark water.

Creating library tools

The possibility of acquiring more profit through a chat app solution is gaining popularity than adopting to monthly plans based chat platforms

Every year there are a lot of articles dedicated to Valentine's Day. I also decided to get involved in this topic and create something original and unusual. The idea was to create a simple Android application with hearts that would have their physical models and interact with each other. Then I added text, sounds, particles and some other effects. The resulting app was working and quite original! In this article I will describe the creation process, as well as the capabilities and pitfalls of the libgdx library.

If you are working with Kubernetes environment then you probably make use of several existing templating tools, some of them being a part of package managers such as Helm or Ksonnet, or just templating languages (Jinja2, Go template etc.). All of them have their own drawbacks as well as advantages and we are going to go through them and write our own tool that will try to combine the best features.

As 2018 has come to an end, now is the time to look towards the future. We typically look out 6 to 12 months and establish topics we want to work on.

As we go we learn and our assessment of some of the topics listed changes. Thus, we may add or drop topics as we go.

We describe some initiatives as «investigations» which means our goal in the next few months is to better understand the problem and potential solutions before scheduling actual feature work. Once an investigation is done, we will update our plan, either deferring the initiative or committing to it.

As always, we will listen to your feedback and adapt our plans if needed.

What's this about

After working on different projects, I've noticed that every one of them had some common problems, regardless of domain, architecture, code convention and so on. Those problems weren't challenging, just a tedious routine: making sure you didn't miss anything stupid and obvious. Instead of doing this routine on a daily basis I became obsessed with seeking solution: some development approach or code convention or whatever that will help me to design a project in a way that will prevent those problems from happening, so I can focus on interesting stuff. That's the goal of this article: to describe those problems and show you that mix of tools and approaches that I found to solve them.
