From the post:
In line with the learning theme that HadoopSphere has been evangelizing, we are pleased to introduce a new feature named FlipBooks. A Hadoop flipbook is a quick reference guide for any topic giving a short summary of key concepts in form of Q&A. Typically with a set of 4 questions, it tries to test your knowledge on the concept.
Curious what you think of this concept?
I looked at a couple of them but four (4) questions seems a bit short.
With the caution that it was probably twenty (20) years ago, I remember the drill software for the Novell Netware CNE program. Organized by subject/class as I recall and certainly a lot more than four (4) questions.
What software would you suggest for authoring similar drill material now?
