You always want to know what the ScrumMaster is doing in your team/company?  Well now it's the time you will find out.  Scrum Alliance has posted a nice article with the task of a SM.  Little remark, this list varies per company. So read it here: http://www.scrumalliance.org/articles/160-what-does-a-scrummaster-do.

You want to use Kanban or you are already using it.  But you also have used Scrum or know Scrum.  Both are the buzz words at this moment in the Agile world.  But still you don't know which one is the best in common or the best for you?  Are they related to each other? Could you easily adapt both together?  Is it easy to make a switch form one to the other?

Henrik Kniberg and Mattias Skarin from InfoQ have writen a book to clear this fog for you.  the book includes following chapters:

• Kanban and Scrum in a nutshell
• Comparison of Kanban and Scrum and other Agile methods
• Practical examples and pitfalls
• Cartoons and diagrams illustrating day-to-day work
• Detailed case study of a Kanban implementation within a Scrum organization
