Hi @bimangunarathne

Unfortunately, unless you have downloaded your markdown files, once you delete your workspace your work is lost in the process.

To launch the course again, you can return to your terminal and run ./setup.sh again.

Hope this helps.

Thanks,

Megan

Hi Joe,

Would you be able to provide me with a few extra details about this.

– Are you running your code in the markdown file or the scratchpad?

– Have you experiencing this issue with the content file or the exercises file or both ?

– Can you send a screenshot of an example of this happening?

Many thanks,

Megan

Hi @eohara_kdb

Apologies, due to formatting issues with our editor, can I ask that you send forward a screenshot of your code instead? 🙂

We are currently working to get this issue resolved for future questions.

Many thanks,

Hi @akila

Do you mind sending me your code for instRef ? This will hopefully help me better assist you.

Thanks,

Megan🙂

Hi @lestat-jin

Thank you for this suggestion ! Our solutions are merely a suggestion for an answer so we are always open to hearing other answers.

We recognise this can be seen as an easier solution so we would be happy to add it to our notebook 🙂

Thanks,

Hi @akila

I’ve taken the below screenshot from the “Scripting and Logging” notebook in the fundamentals course.

Simply use the system”l ” command followed by the path name.

Hope this helps!

Hi @jeanluck

Can you send me your exact answer for exercise 2.2 so I can spot where you might be going wrong?

Thanks,

Thank you @unterrainer_ale for providing an example.

Hi Joe,

So ‘ : : ‘ is the generic null value in Q. If a function returns no value it actually returns ‘ : : ‘ .

Take a look at the example below, when this function is passed a parameter of 4, it returns 4.

But if we don’t pass it anything, it returns null.

Hope this helps!

Thanks,

Megan

Hi Joe,

Can you send an example of a code snippet you are trying to run in the rendered markdown file that causes this problem ? Such as this:

I may have to access your server to get a closer look.

Many thanks,

Hi @jeanluck

You currently have your select statement commentated out, are you removing this when submitting your answer?

Hi @lestat-jin

If we take a look at the format for the functional form of each (screenshot below) you can see the quote is used outside the square brackets.

So if I were to edit your answer it would look like:

allPaths:{[dir] sv'[`;dir, 'k where(k:key dir) like "[0-9]*"]}

I have removed the quote infront of dir and included it between sv and the square brackets as indicated in the documentation as this represents using each in functional form.

Let me know if this answers your question !

Thanks,

Megan

Hi @lestat-jin

` sv’… is the dyadic form of each, x f’y: https://code.kx.com/q/ref/maps/#each
When ‘ is prefix — not in an adverb position — that’s signal/throw: https://code.kx.com/q/ref/signal/

If you have any questions about this, feel free to reach out!

Thanks,

Megan
