How to Pass the Professional Scrum Master III (PSM III) Assessment
It’s been a year and a half since I wrote my most successful blog article Professional Scrum Master I (PSM I) Exam Preparation. Since then, hundreds of people have subscribed to the site, many of whom have gone on to earn their PSM I certificate.

Scrum Guide 2013
Ken Schwaber and Jeff Sutherland, the creators of Scrum, have issued a new version of the official Scrum Guide, dated July 2013.
They have produced a video where they discuss the changes in the new Scrum Guide.

All references to the old guide mean the Scrum Guide October 2011. All references to the new guide mean the Scrum Guide July 2013
CSS and Specificity
Working on a basic MVC 3 application, I added in a jQuery UI datepicker. After getting it to work, I decided to re-size the input box. I did this by adding an entry at the bottom of the applications Site.css file as follows:
.date {
width: 100px;
}
No matter what I did, it wouldn’t work. I then decided to run the application in Chrome and use the Developer Tools provided to examine the page. I discovered that my .date entry was being superceded by a input entry earlier in the CSS file.
Research led me to this article on specificity. It appears that my .date entry is not as specific as an input[type=text] entry. The rules of specificity say that .date is worth ten points (for the class) but that input[type=text] is worth 11 points (1 point for the ‘input’ element and ten points for the [type=text] attribute.
