All of my existing tutorials are being updated over the next few weeks with some small but very nice changes.
These changes are all inspired by my own experience of teaching. Firstly, all articles within tutorials will now have learning outcomes - what you are expected to know by the end of the article. Secondly, I am adding an "Over to you" section to many tutorials that allows you to try out some tasks based on what has been covered in the article. Thirdly I am now working on actively adding downloadable versions of all code samples across my website - this will include tutorials as well as pages like ZPE. This, again, will take a while for me to finish.
