← IDEAS? What Should We Do Next?

I suggest you ...

You've used all your votes and won't be able to post a new idea, but you can still search and comment on existing ideas.

There are two ways to get more votes:

  • When an admin closes an idea you've voted on, you'll get your votes back from that idea.
  • You can remove your votes from an open idea you support.
  • To see ideas you have already voted on, select the "My feedback" filter and select "My open ideas".
(thinking…)

Enter your idea and we'll search to see if someone has already suggested it.

If a similar idea already exists, you can support and comment on it.

If it doesn't exist, you can post your idea so others can support it.

Enter your idea and we'll search to see if someone has already suggested it.

  2. Correction in Lab-String operations

    In the lab of string operations the explanation of upper method in string operations "this method converts lower case characters to upper case characters" should be present instead of "this method converts upper case characters to lower case characters"

  3. I believe the anser to the following question is wrong.

    Retrieve the elements stored at index 1,2, and 3 of 'a_list'

    I suggest the answer should be:

    A[1:4]

    ['hello', [1, 2, 3], True]

    The suggested answer int he docs is "a_list[1:3]" which only returns two elements.

  6. availability of other video format asides HD

    there should be an option for selecting our prefferred video quality of the videos in the module.
    The only option that exists right now is HD, and for some course participants like me, watching in HD format may incur heavy data fees.

  12. There's a slight mistake in a lin of code

    Hi!
    Just to let you know that in one of the code blocks in "Functions in R" lab has a missing "" in both mydata variables. Running the code returns an error. [check the big conditional function about movie watch if good rating)
    On the other hand, it's a good debugging exercise.
    Kind regards,

    Data needed to be uploaded/download may be huge. 7z format is widely used and one of the best existing formats fo far.

  17. The tutorials are not clear for a novice

    It seems that your tutorials mostly miss the mark (at least for me). I was really interested in SeaHorse, I was able to run the first regression tutorial, saw the gears spin, but don't see any results. All I can do is download the workflow. There are various modules in the workflow, but no description of what they do or why they are there. There are lots of other modules in the toolbox, but no real indication of how to use them.

  20. Feedback on support

    This is worst kind of support I have seen from IBM.

    My ticket is pending for last one and a half month. Neither my ticket is resolved nor I am getting any response from support team(Bryan chiru)

    This is highly unprofessional.
