    Hello its a me again drifter1! Another wonderful Steemtastic Year is passing by. I hope that all your dreams and passions will finally be fulfilled in the new year, and that this new year will be full of love, happiness and most importantly good health! This year was clearly something. We were in a bear-market, but could spend our hardly worked money of 2017 :P and earn money for the future, that might be 2019! After so many months it's also time for a Recap..So, let's get into a recap, where I will as always split the articles into categories!

     In this category are programming posts in C and Java that have to do with Inter-process or Inter-network communication. I use Linux for the C posts and get into everything you need to get started with Socket programming. In Java we simply get into how the Java Networking API works in some simple examples. I also started with Distributed algorithms using MPI, which is something that I want to get back to soon :)

     This category is all about maths...Here we get into all the basic and more advanced concepts of many different branches of math. I know that many of you hate and/or are scared of math, but I will try to make everything seem as simple as possible, so that you only get to know what you actually need. Through this you will be able to these advanced mathematics in Physics and mainly Game Design/Development, which needs advanced Maths/Physics if you want to will also get into how we use it in computer science or information technology Code everything on your own!

    After that we can also do Optimizations, Extensions and more if you like :)

    What's next?

    Other new "series" that are in plan are:

    • Web Development series in HTML, CSS, Javascript, php and SQL, under a new Category called "Web Dev"
    • The languages C#, Python, ... under Programming
    • Artificial intelligence -> Theory and Programming implementation, which means that this series might be a part of "Programming"
    • Parallel programming in OpenMP, CUDA, OpenCL, ..., maybe in a new category of "Parallel Programming", but we will see
    • Databases for the Web Dev series
    • Game development in Unity (that's why C# is in this list) or Unreal Engine

    And this is actually it for this article and I hope that you enjoy such Recaps!
