give an alternative for ibm.box.com
Hi,
could you please reconsider having your files (images and pdf's) on your server -bigdatauniversity.com- instead of ibm.box.com ?Eventually please add a pure text transcript as an alternative.
due to the company policy I have blocked any pages with file-sharing, so I can not see the images in test questions and can not view any files hosted on ibm.box.com

improve Data Science 101 - Module 1
None of the links to the reading material actually work, I tried the links for Modules 1, 2 and 3. One of the discussion topic responses in Module 1 suggests a link to Google where a sample Chapter 6 of the book is available, but the Review Questions require answers from other Chapters, e.g. the question re Walmart is not in Chapter 6 but in Chapter 1. The selection of answers to the New York Times question do not match the actual article from April 2015 (can easily be found using Google).
Overall I'd say this course is a disappointment…1 vote -
Use a Spellchecker Before Publication
In "Data Science Methodology", there are too many grammatical errors and answer errors in the reviews and exam for me to type out.
Before a class is published online, it should have at least passed a basic spell and grammar check. It looks unprofessional.
My suggestion is:
Use a spellchecker before you upload it online. Also, at least one person should go through the reviews and exams to check if everything "looks" okay.
I wanted this course to be supplemental material for my students. But the way it is now, I cannot suggest "Data Science Methodology" to them.

Allow labs to be done on cloud instead of VMware images
It would be great if I can perform hands-on-labs for Hadoop related courses on the cloud rather than have to download huge VMware images.

Session management
Hello,
New design of your website is just awesome and I appreciate your efforts. But I would like to draw your attention that session of your website is not working properly.
- After logging in, when I go to select the courses it redirects me to the login page showing that you are not logged in.
- Even when I go to update my profile the same is happening with me.
It is really very frustrating. Please do something. I understand this is a beta version so I am just trying to help you.Thank you

add an autoplay feature
It might be nice to 'autoplay' a module instead of having to click for the next video. Or possibly add a next arrow at the lower right of the video?
