Oh yes, Christmas! It’s almost that season of the year again. And to shorten the time between the 1st of December and Christmas Eve’, I thought about a bit more interesting advent calendar than one, that only has chocolate in it. This electronic advent calendar offers a riddle that you can create for a loved one or a friend and give it to them so they can try to solve it before Christmas arrives. It offers a clue every day and it presents all unlocked clues on a website that runs on the device itself. The only two things it needs to work is a power supply and a WiFi network it can connect to. And the best thing is: It is really simple to build and it can be re-used every year and it can also be used for other occasions (for example Valentine’s Day)!

Some time ago I wrote an article about how to get started with Windows 10 App development. This article will introduce you to Mac-Apps and will guide you through the process of programming one with Xamarin and C#.
Easy to follow video included at the end of the article.
Our last series was a big success and we decided to take it a step further with an Advanced Programming series, which will start in Dec. 2016. But for today I want to give you a quick tip for faster coding in IntelliJ IDEA! Continue reading Programming Basics – Addendum: IntelliJ QuickTip
Welcome to the last part of the programming basics series! In this series we’ll cover what exceptions are and how you deal with them.
If you’ve made all the examples, that are featured throughout the series, you might have encountered something like this:
This particular runtime error is caused by a wrong user input. It’s not caused by faulty code. Errors like this usually crash your application and a user has to restart it, in order to continue using it. In this part we’ll cover how to deal with such errors.

In this part we’ll discuss the most important concept in an object oriented language: Objects. So far you’ve already learned how to write a single class and you’ve put all your functionality into a single class. But we’ve used objects in our examples already and in this part you’ll learn what objects are and how you can use them!
This part will teach you, how to compare values and control the flow of your program. It will also teach you, how to repeat a part of your program for a defined number of times, which is very useful for tasks like processing user input or printing out data.
This is a very long article. I didn’t plan to make it this long, but I ended up writing a lot about this topic. I recommend you to split it into half after the ‘Large choices’ section and take a break. However, let’s get started!
So far you’ve learnt what methods and variables are and how to use them. In the case of variables you have also seen, how to get a user’s input and store it. If you want to store multiple inputs of the same type, for example numbers for a calculator, you’ll have to create different variables for each input, right?
In this part you’ll learn, how to store multiple values into one variable (sort of).
