  2. Should allow to login using username

    I think, it'd be easier to maintain & use the account with multiple options available. it's good that you provide multiple email options, but it'd be great if your provide to login using username. What is the use of a unique username if it can't be used instead of your email id for login? I changed my email id & was unable to login after that as your database didn't receive my other id. So, that made me lose all my progress with the previous account. Thank you!

  5. Size of slides in Video

    Hey, thanks for the courses and videos. The slides in the videos are too small to read the details even in the full screen mode. If your intention is to educate the public, why make it so difficult for us to read the slides.

  8. Support for more web browsers than just Chrome

    I was not able to access the Lab content in the R101 course when I used FireFox. Only when I used Chrome was I able to access the lab content. This is a limitation of the Cognitive Class Labs/Data Scientist Workbench. I also noticed that Seahorse only supports Chrome. I would like to see support for more browsers, and not just Chrome.

  10. update the link in DS0105EN>Mod 1> Creating an account page

    In DS0105EN>Mod 1> Creating an account, it asks us to go to datascientistworkbench.com and create an account. But if you try to do it, it redirects to the Cognitive class page. I spend a while going in circles-frustrated that I was following the steps in the video and yet not getting to the virtual Lab page...It was only when I got to the lab page that I saw that the link is now https://labs.cognitiveclass.ai/.... It might help putting a note in the "create an account" video page saying that the new link is https://labs.cognitiveclass.ai/.. This would make it…

  11. Astonished at the choice of instructor for a core course - Hadoop 101

    Hello,
    I am simply astonished at the choice of instructor for such a vital course as Hadoop 101. Asma Desai's reads at rocket speed and the narration is terribly incoherent.

    If I have to pause the video at an important instant, before I can click the pause button, she squeezes in a dozen extra words. Now I have to move the slider to a few seconds back and re-try the pause operation.

    This has contributed to an extremely annoying User experience while taking Hadoop 101.

    Please replace the Hadoop 101 course video with someone who knows how to teach. I…

  12. show the correct answer and explanation why when I get a fall for a specific review question in the final check

    Hi, I really like the courses provided by the BigData University. However, I find it is time-consuming to go back to find the answers from the previous modules when I got a fall in a review question. Therefore, I suggest you could automatically show a chat box after I click the FINAL CHECK, so that I will get the full explanation about why this option is correct and why that option is incorrect, no matter I pass the final check or fall. Many thanks. Hope I have present my suggestion clearly. If you have any question about my suggestion, please…

  13. The review question in the Demo section is incorrect

    The review question posed in the Demo section is actually one of the answers. The question can be inferred from the other answers but needs to be corrected.

  14. make notebooks file downloadable instead of running in the cloud

    it's great that you offer the notebook on the cloud. But if your connection is not good (especially in China where I currently live), it's better to download it and run it locally on your computer, especially if you use a software to open the notebook directely like Pineapple or nteract : https://github.com/nteract/nteract

    Yanick, thank you for an excellent suggestion. We do understand the desire to do hands-on labs without a connection to the internet and we are looking to address it.

  15. Not updated

    Hello,

    I'm currently doing the Hadoop 101 course. I found that the facilities for Lab is no longer accessible and the training guide for Lab is not updated. Can you guys update all the required information? Thanks.

  18. Highlight items that you are clicking on in the videos.

    I just watched my first video and I just wanted make a suggestion (as I am a video developer also) to be more clear as to where you are clicking with your mouse. In this case it was the menu on the left hand side, but windows were popping up and I had no idea why. You can perhaps add cursor effects or callouts to draw viewers attention. thanks.

    can i do that. i am giving proper references to congnitive class ai and even want to put a permanent link to courses here.

    is it ok for me to use course material for my blog?
