Challenges

Below you can download a small set of challenges that go with some of the playgrounds. Some people might prefer the wording of "exercises" rather than "challenges", but the intent is to give you some good concrete puzzles to try to figure out with self-created data and then double-checked using an appropriate playground. I will create more challenge documents in the future, but probably not until August 2018.

Each file is a PDF that has been zipped. When you click on the link the file will automatically download. For over 90% of you the file will then auto-decompress when on your hard drive and all you'll see is the PDF. For a small percentage of users with older computers you may need to double-click the zip file to manually unzip and reveal the PDF document.
