I see your email with code went out last evening, the job to send emails runs hourly so there might have been a delay from when you messaged.
Can you confirm you received it now?

Thanks for flagging this @lestat-jin , Rian’s correction should work for you.
And I have now updated the notebook so new users will not run into this same issue, to pull the updated notebook you can navigate to Terminal and run git fetch and git pull to get the corrected notebook.

I just bounced your instance and rebooted so if you could try again now please?
The steps I followed are here btw https://learninghub.kx.com/forums/topic/kx-developer-fails-on-startup/#post-42252

Does retrying and opening in a different tab work?

@akila It seems you have set permissions on this remote process as required in exercise 3.4 so you can no longer access with hopen alone.
Try authorising with one of the users in users.txt instead for example:
hopen `::5099:jmurphy:bahrain22

@kokuyo you can restore your file by doing a git checkout on a terminal window:
– Open a new Launcher (+ in top navigation) window and select Terminal
– Run git status to see files that have changed and git diff to see code changes
– You can see the deleted code here and run git checkout on the file you wish to restore

What does uniqueOpts variable return in the console? Would you be able to share a screen shot of this with your code and result instead of code snippet too please?
I will be better able to assist if I can see your code and output example as we have some issues with code formatting on the forums due to be resolved soon https://learninghub.kx.com/forums/topic/known-forum-ux-issues-and-resolutions/

@jpandza The Blocked message is correct, the capstone has been setup such that process 5010 is restricted in that it only allowes calls to 2 APIs as detailed in the instructions.

Hi @Nicky this error can be ignored – you can open KX Developer now from the Launcher window.

Hi @Hizmy
part error indicates an something wrong with the partitions in the HDB.
I had a look at your instance and see a rogue file in the HDB directory called csvOutputPath. I removed this file.
Can you please try again?

@jeanluck to get you unblocked quickly it will be best if you can share your answers file with me in a DM or to evangelism@kx.com. Then I can better investigate what is going wrong for you as is hard to diagnose without seeing what you have ran.

@rlakkireddy Have you got kdb installed and the alias set so you can run q to invoke kdb+?

- How was kc.lic created?
- Is QHOME set?
- Can you share screenshots of the above path and variable definition?
Also FYI you can run this application on the free KX Academy sandbox – no need for you to install anything locally.

@jeanluck is your issue on 1.4/2.2 solved now? Or are you still stuck?
Thanks for letting us know and we will clarify that question by specifying we want a date partitioned table in the question.
Re. 3.5 I am not following, can you send a screenshot of the discrepancy please and we will have a look and update if needed.
Your feedback is appreciated as we aim to continuously improve the course materials. 🙂

After writing table to disk using .Q.dpft and loading into memory you should see the date column on your table. You do not need to pass the column name date as in your example, the third parameter should be the column to key on, in this case sensorId. See an example here of what that looks like: https://code.kx.com/q/ref/dotq/#dpft-save-table
Note in that example the table in memory is first deleted and then the table on disk is reloaded – only after loading from disk does date then appear when calling the table or using meta. So for exercise 2.2 you should see date appear without needing to do anything other load table into memory as long as your .Q.dpft worked correctly.
If you can get all your exercise 1 passing thats a good sign .Q.dpft worked correctly. Then use \l to load into memory.

@Mohamed This is very odd and something we haven’t been able to recreate.
What should happen upon clicking the “Launch KX Sandbox” link is a new tab will open with this link below, this link has a redirect to pull a git repo into a fully cloud hosted (on our side) environment so wouldn’t expect it to cause much load on your side.
Can you let us know what happens when you try open this link below so we can better assist?
