Coursera:
1) Programming Cloud Services for Android Handheld Systems: Submitted Quiz 6 and Assignment 2 in the past Sunday. The new assignment looked challenging at first after reading the README file and going through the source codes. Fortunately, code examples provided oAuth2 package that could directly use in the Gradle project. Furthermore, no effort to write CRUD methods to retrieve records from database because Spring Framework’s CRUDRespository class generates them automatically. My solution was create a Spring Controller to expose methods to receive HTTP requests from users. Then, the requests were delegated to CRUDRespository subclass to retrieve data and return it to users. Very simple!!!!

Programming:

2) Start my third AngularJS project that adds photo albums to store pictures taken in Open source Workshops and local meetup groups. This time, the project is bootstrap by Yeoman and Gulp because Matthew told me Gulp is better build system than Grunt. After using angular-gulp-generator to generate the skeleton project, I have to agree with his assessment.

I got it wrong in M101P exam and did not bother to watch the answer video. The same question appears again and I have no idea which options to choose.

All MongoDB university courses are great and I hope many people feel the same way I do.
