statistics: US States Schools Ranking

An interesting example of statistical data analysis and visualizations.
NJ is ranked 3rd in both measured rankings (quality & safety), but it is overall 2nd :)
First map chart displays only one dimension.
Also check small print on meaning of "safety", it is quite limited.

This reminds me of textbook for statistics, How to Lie with Statistics
that is now available online free, on both & Google Books. 
It is likely out of copyright, since it was first published in 1954.
It even has a page turner and a voice reader!

As the author of the book suggests, those who present data already know the tricks.
It is the rest of people who can benefit from learning how to spot them.

Azure AD B2C

Microsoft Azure AD is a very useful authentication system.
It enables integrated user management, as well as integration with 3rd party providers,
such as Facebook, Google, Outlook, Amazon, LinkedIn, Yahoo etc.
It can be used for both internal as well as public facing web and mobile applications.
And it can also synchronize with on premise Active Directory.

Azure Active Directory B2C is now generally available in North America | Blog | Microsoft Azure
