    • update the course material

      Some of the commands listed in the lab is outdated and deprecated, I'd suggest review the content often and update it. Or at least put reference documentation in the course description so new learners can refer to up to date documentation. I'm available to discuss this further or help out.

      • Correct the link to docker-entrypoint.sh for Mongo 3.4

        There's a link the the docker-entrypoint.sh script for the Mongo 3.4 docker container. Or rather that's what's supposed to be linked. The link is actually point to the script of Mongo 3.0, which is not on Github.

        Broken Link:
        https://github.com/docker-library/mongo/blob/master/3.0/docker-entrypoint.sh

        Correct Link:
        https://github.com/docker-library/mongo/blob/master/3.4/docker-entrypoint.sh

        • fix Scala kernel

          The Scala kernel isn't working, making it difficult to get some hands on experience on labs that use the Scala kernel, eg. all of the Spark labs.

          Thank you

                    Group courses to define graduation series from foundation to expert. For example, I completed a foundation or introductory course which should be a prerequisite to a more advanced course, I should know which one to take next.

                      There is an error as it shows Yhat = lm.predict(X) and this is incorrect. must be Z

                          But acually,python can't not work and also crashed;here i download the file and cancel the(dropdown list) set ,and i upload to my box cloud,so here you can go to download in this URL (https://app.box.com/s/zkd6hlp15nr38581ew0kifswwncaacwr), and you have to check out what cloumns have and to decide to use .drop method

                          and now, when you download file finished and use df=pd.read_excel( your filepath,sheet_name=' Canada by Citizenship (2)', skiprows=range(20), skip_footer=2)
                          ) BY THE WAY,your filepath is different from me, don't forgrt to check…

                            • Advanced course paths similar to other platforms

                              We need more hands on experience and intermediate ad advanced level courses like coursera offers for free because it's quite expensive..! This platform is very different when compared to those because we have the proof to showcase our talents immediately after we finish our final test..! And all the courses are free..😊

                                • Create database/tables in Hive using ssh to systemt.datascientistworkbench.com

                                  Good Day,

                                  I ssh systemt.datascientistworkbench.com. Then I start hive using "hive" command. I try to create database/tables in hive but it says I don't have access.

                                  I see many test kind of hive databases which people have created. How can I create database/tables in hive?

                                  Please advise.

                                  Thanks.

                                  -Shakeel
