Dear community, some time ago I saw a competition on StackExchange. It was about developing a scalable Christmas tree. Everyone was allowed to use the programming language he wanted. The competition is already 5 years old, but I like the results and the basic idea. So here's a Christmas tree in ABAP (source code on GitHub via abapGit). Hope you like plain ASCII art 🙂
By the way if there is some time left during christmas time, here are a few suggestions.
Visit TechnologyRadar from ThoughtWorks. A lot of interesting things to read about and a good source for further research (e.g. Chaos Katas).
